Two defects in the same path, both measured on the 1,393-agent refactor run.

1. A nested orchestrator (depth > 0) runs delegate_task synchronously by
   design: it needs its workers' results inside its own turn. But the
   sequential tool runner put every tool call under the generic 420 s
   deadline, and delegate_task was not exempt, so every batch longer than
   seven minutes returned "timed out after 420.0s" while the children kept
   running as orphans. 332 such timeouts in 234 orchestrator sessions; only
   89 nested delegate_task calls in the whole run ever returned a real result.
   The orchestrators then spent 388 h of wall time polling: 1,526 reads of
   the live transcript files, 551 list actions, 242 h of explicit sleep,
   about $4k of API turns. delegate_task is now exempt from the sequential
   deadline (the batch owns its liveness: per-child heartbeats, the stale
   monitor, delegation.child_timeout_seconds).

   Live A/B, depth-1 orchestrator dispatching a 75 s leaf with the deadline
   set to 40 s (glm-5.3-flash via Nous): main -> "Error executing tool
   'delegate_task': timed out after 40.0s", leaf result lost; branch ->
   orchestrator blocked 161 s and returned the leaf's LEAF_DONE_MARKER.

2. _parent_summary_char_budget computed the parent's context headroom from
   session_prompt_tokens, which is the running SUM of prompt tokens over
   every API call in the session. After a few hundred calls it exceeds any
   window, headroom goes negative, and every child summary collapses to the
   2,000-char floor with the full text spilled to disk. All 1,393 child
   summaries in the run were truncated this way; the orchestrator planned
   from stubs. The budget now reads the last call's prompt_tokens from
   _last_turn_usage.

Tests: delegate_task is in the exempt set and the set is narrow; budget for
a long-lived parent equals the budget for a fresh parent with the same
current prompt, and exceeds the floor.

Subject: [PATCH 002/276] fix(approval): a grep inside "$(...)" no longer trips
 the hardline "malformed payload" block

The quoted-grep scanner tokenizes from the grep's position to decide which
quoted operand is inert data. _shell_tokens_with_spans lexed from there to
the END of the top-level segment, so for a grep nested in a substitution
such as

    sed -n "$(grep -n X f | cut -d: -f1),+3p" f

it read past the closing ")" into the enclosing command, met the outer
closing double quote as an opener, ended in quote state, returned None
("malformed"), and detect_hardline_command reported the whole command as
being on the unconditional blocklist. Nothing about the command was
dangerous. In the 1,393-agent refactor run this fired 546 times across the
workers (every one a false positive; 318 of 323 retries succeeded by
rewording), and three times on the maintainer's own session in one day.

The lexer now stops at the end of the simple command it was asked to lex:
an unquoted list separator or pipe or newline, or the ")" / backtick that
closes the substitution it sits inside (tracking $(...) depth opened after
start so a nested substitution's closer is not mistaken for the outer one).
Genuinely unbalanced quoting still returns None and still fails closed;
every hardline pattern is unchanged.

Tests: six substitution shapes lex clean and are not hardline; the lexer
yields exactly the grep's own words; unterminated quoting still blocks;
rm -rf / , $(rm -rf /) and shutdown still block.

Subject: [PATCH 003/276] fix(goal): the judge only sees the goal's own
 background processes, and a pid/session wait barrier expires after 30 min

In a fan-out run the /goal loop parked for 3 h 22 min at the end on a
grandchild's poller (waiting_on_session=proc_21a6fe2369a1, 00:47 -> 04:09)
while the root itself had nothing running. Every one of the root's 7 logged
judge verdicts was WAIT on a child-owned process.

Two causes. gather_background_processes() was called with no task_id from
both goal-loop callers (CLI cli_loops_mixin, gateway run_goals), and the
registry's task_id is the CONTAINER key, which collapses to one value for
every agent in the process, so the judge's process list was every one of
~1,300 subagents' pollers. And a pid/session barrier had no ceiling: once
the judge said WAIT on a session that never exits, nothing resumed judging;
waiting_since was recorded and never read.

Now list_sessions() reports owner_task_id (the RAW spawning id the
registry already keeps for ownership checks), gather_background_processes
takes owner_task_id and both callers pass their own session id (CLI turns
register processes under self.session_id; gateway turns under
turn_ctx.session_id), and is_waiting() ages out a pid/session barrier
after _MAX_BARRIER_WAIT_S (30 min). Timed barriers keep their own deadline.

Tests: only the owning session's running processes are returned when
owner_task_id is given (unfiltered behaviour unchanged); a live barrier
older than the ceiling clears and judging resumes.

Subject: [PATCH 005/276] feat(delegation): subagents compress at an absolute
 context cap (delegation.compression_threshold_tokens, default 200K)

A delegate_task child inherits the compression threshold as a RATIO of the
model window. On a 1M-window model at the run's configured 0.85 that is an
850K-token trigger: in the 1,393-agent refactor run 1,373 of 1,375 children
never compressed once, 62% of all API calls carried >150K of context, and the
calls above 200K carried ~$10.9k of the $19.3k bill (58% of it cache WRITES,
i.e. re-sending a 300-800K prefix on every call). A sawtooth replay of the
logged calls with a 200K cap / 65K floor cuts context spend by ~49% (~$7k).

Children are brief-driven and disposable; they re-read their brief and the
files they touch, so a large window buys them little. New
delegation.compression_threshold_tokens (default 200000) is applied to the
child's ContextCompressor right after construction as the lower of it and
any global compression.threshold_tokens; the parent's own trigger is
untouched. 0 disables the subagent-specific cap. The compressor applies
threshold_tokens_cap on first window resolution, so this is byte-equivalent
to the user having set compression.threshold_tokens for the child.

Live through the real spawn path (_build_child_agent, real imports, temp
HERMES_HOME, 1M-window model): main child trigger 500,000 / branch 200,000;
parent 500,000 on both.

Tests (3): default caps a 1M child at 200K; the cap is the lower of the
delegation and global values and never raises a small-window child's
trigger; 0 disables and an already-resolved trigger is re-clamped.

 `delegation.request_overrides` works on **all three** resolution branches — direct `base_url`, named `provider`, and pure inherit — so it always takes effect. Top-level keys are API kwargs (e.g. `service_tier`); an `extra_body` sub-dict is merged into the request's `extra_body`. Explicit values merge **over** runtime- or parent-derived overrides: explicit top-level keys win, and `extra_body` is deep-merged one level, so a provider's own request personality (e.g. `thinking: {type: disabled}`) survives unless your key redefines it.

Subject: [PATCH 006/276] fix(nous): adopt a fresh agent key before the one in
 hand expires, and start the keepalive in every process that routes to Nous

The Nous agent key lives 3,599 s. In the 1,393-agent refactor run every
in-process agent learned about the hourly expiry from its own 401: 620
authentication_error 401s in the logged window (177 in one hour), each a
failed attempt the model never saw, and the credential pool benched the
sole credential for all of them at once. At 08:30 the storm took the
parent process down.

Two gaps. The proactive refresher (hermes_cli/nous_auth_keepalive.py) is
started only by the gateway and the web server; the CLI process, and every
subagent built inside it, never started it. And even with a fresh key in
the store, nothing adopted it before a request: a request went out with
whatever key the agent was constructed with until it 401'd.

Now _finalize_routing starts the keepalive (idempotent, process-wide,
daemon) whenever an agent resolves onto provider "nous", and
prepare_iteration calls _adopt_nous_key_before_expiry(): the agent key is
a JWT, its exp is read locally, and inside a 180 s skew the store is
re-read under the auth-store lock with force_refresh=False, so the
keepalive's (or a peer's) fresh key is adopted without a POST; when none
exists, ONE refresh runs there instead of N reactive ones after N 401s.
_try_refresh_nous_client_credentials no longer rebuilds the client when
the store returns the key already in hand.

Live A/B (local server: 401s any bearer but FRESH; store patched to hold
FRESH; 40 agents holding a JWT that expires in 30 s fire concurrently):
main 40 x 401 then recover, branch 0 x 401.

Tests (4): far from expiry the store is not touched; inside the skew the
store's fresh key is adopted with force_refresh=False; the same key back
from the store is not re-adopted; a real AIAgent routed to nous starts

Subject: [PATCH 007/276] fix(terminal): a foreground timeout above the cap
 runs as a tracked background process instead of being refused

`Foreground timeout Ns exceeds the maximum of 600s` was the second most
frequent tool-layer error in the 1,393-agent refactor run: 454 refusals
(285 asked 900 s, 41 asked 620, 20 asked 1800), 251 of them test-suite
invocations. Every retry was mechanical: lower the timeout (167), split into
sleeps (82) or re-send with background=true (86). The schema invited it
("set high for long tasks", max 600) while the suites take 10-30 min.

An over-cap foreground timeout is a bounded job the caller wants to wait
for. terminal_tool now runs it as a tracked background process with
notify_on_complete=true and says so in the result
(`promoted_from_foreground`, naming the requested and cap seconds, with
"do NOT re-run it"); the schema text describes the new behaviour. The
`&`/nohup/setsid and long-lived-server guidance stays a refusal: those need
the command itself rewritten, which the tool cannot do safely.

Live (real local backend): main refuses `sleep 1; echo LIVE_OK` at
timeout=900; branch returns a proc_* session with notify_on_complete and
the note, and the command runs once.

Tests: the promotion test runs a real command through the real registry and
asserts the result shape plus that it executed exactly once in the
background; `&` still refuses; schema text updated. Terminal/process suites
(27 files) 378 passed.

Subject: [PATCH 008/276] feat(delegation): a failed child of a still-running
 detached fan-out is surfaced to the parent immediately
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Batches join on the slowest sibling before ONE consolidated block re-enters
(the design: one results block per fan-out). Failure is the case that
should not wait. In the 1,393-agent refactor run every wave-1 child died in
the 08:29 401 storm; the parent learned of it at 09:36, when the batch's
"unknown outcome" block finally arrived: 66 minutes of a dead wave with
nothing running, the single largest idle gap of the run.

_run_children_parallel, for DETACHED batches only (the sync path prints a
completion line the parent is already watching), pushes ONE
type="async_delegation" event with task_failure_notice=True and a
single-entry results list when a child ends in a failure status while
siblings are still pending. Same event shape and routing fields as the
batch result, so every drain/ownership/format path treats it identically;
the batch record is not finalized and its consolidated result still
arrives unchanged. The formatter renders
"[ASYNC DELEGATION TASK FAILED — <id>, task i/n]" with the task, status,
error and live transcript path, and says the batch result is still coming.
The TUI dedup key distinguishes a notice from the final result and from a
sibling's notice.

Live through the real detached dispatch (3 children, one fails at 0.1 s,
two succeed at 8 s): notice drained at t+0.3 s, batch final at t+8.4 s. On
main the parent hears nothing until t+8.4 s.

Tests (2): the notice reaches the queue with the record's routing fields
while the record stays running, and formats as an early warning; no notice
for a finished batch; dedup key differs from the final result.
Delegation/registry/notification suites (129 files) 1,344 passed.

Subject: [PATCH 009/276] feat(file_tools): write_file says when it just
 re-sent a large file that was already on disk

In the 1,393-agent refactor run write_file carried 92.8M chars of content
(23.2M output tokens, ~$580, 20% of all output tokens). 661 of those calls
were read -> whole-file rewrite of an existing file >20k chars (24.9M
chars, ~$155): 130k-char agent/model_metadata.py, 109k
model_setup_flows.py, 107k google_chat/adapter.py, re-sent in full to
change a few lines. Meanwhile patch succeeded 4,602/4,617 (99.7%) at 1.3k
chars per call. The tool result is the only place the model reads, so the
cost signal goes there.

When an overwrite targets an existing file and both old and new content
are >=20k chars, write_file diffs them by line (difflib, autojunk off)
and, if >=80% of lines are unchanged, adds a `hint` naming the unchanged
count, the changed count, the size, and "use patch". The write itself is
unchanged and still happens; new files, small files and genuine rewrites
get no hint. 300 ms on the 119k-char model_metadata.py.

Tests (2): a 40k-char file with 2 lines changed gets the hint and is
written; a new file, a small file and a wholly rewritten file get none.

Subject: [PATCH 010/276] fix(goal): /goal <text> kicks the loop with a short
 pointer when the user's last message already carries the goal

`/goal <text>` queues the goal text as the next user turn to start the loop.
When that text is what the user just pasted (a handoff note, a plan the agent
already has), the kickoff re-sends it verbatim: in the 1,393-agent run
`/goal <2,000-char handoff>` came 16 minutes after the same note was pasted
as a message, and the agent spent 11 API calls / 6 min deciding it was a
replay, with the note duplicated in context from then on.

_goal_kick_prompt() compares the normalized goal against the LAST user
message (string or block content); when contained, the kick is a one-line
'[Goal set] Continue with the goal you were just given; there is no need to
re-read it.' Otherwise the goal text is sent as before. Both /goal <text>
and /goal draft use it.

Tests (2): a just-pasted goal (plain and block content) kicks with the
pointer; a new goal, an unrelated last message, and a goal pasted in an
OLDER turn kick verbatim.

Subject: [PATCH 012/276] fix(tools): every sandbox creator uses the shared
 container_config shaper (#76906, #87995, #84027, #100019)

The prompt backend-probe and execute_code each kept a private (key, default) table for
container_config and drifted from the terminal tool's: the probe omitted docker_network, so
under docker_network: false it started a bridge-networked container; execute_code omitted
docker_extra_args, docker_forward_env and docker_env, so a sandbox created from that path
lost the operator's settings. Both now call terminal_tool_backends._container_config_from_config.

Salvaged from #62023 by @sagitario-jpn (the probe docker_network fix), widened to the whole class.

Subject: [PATCH 014/276] fix(approval): a quoted $(...)/backtick body keeps
 its command boundaries when newlines are masked; a backtick operand is not a
 closer

Independent review of the first fix found two defects. Bounding the grep lexer
removed the old "malformed payload" floor, and that floor had been the ONLY thing
blocking a hardline command hidden after a newline inside a double-quoted
$(grep ...) substitution: _mask_quoted_newlines treated the newline as quoted
DATA and replaced it with a space, so the later command-start pass saw
`/dev/null reboot` as an operand and the public guards approved a hardline
command with no callback. A substitution body inside double quotes is
executable; the masker now recurses into $(...) and backtick bodies with a fresh
quote state so a newline there stays a command boundary. The witness now blocks
as "system shutdown/reboot" (the correct verdict), as do the ; / && / | / nested
/ backtick variants.

Second: the lexer stopped at ANY backtick as if it closed an enclosing
substitution, so a grep with a backtick OPERAND lost its operands and was
reported malformed (a new false positive). A backtick opened after the grep is
an operand substitution; only an unmatched one closes the enclosing command.

Tests: the six hardline-inside-substitution shapes block as themselves; the
public guard blocks with zero approval callbacks; the backtick operand, a data
pattern and a quoted-newline commit message stay allowed. Approval/hardline
suites: 637 passed; the one failure (real-binary sort payload probe) fails
identically on main.

Subject: [PATCH 015/276] fix(nous): pre-expiry adoption only ever swaps to a
 key for the SAME account

Independent review of the first fix found a credential-identity takeover:
_adopt_nous_key_before_expiry() called the singleton resolver
unconditionally, so an agent running on an explicitly supplied (or
pool-selected) account-A key near expiry was moved onto the logged-in
account-B key from auth.json before the A key had even failed, and the next
real SDK request went out as B. That silently changes who is billed.

The adoption now reads the `sub` claim of the key in hand and passes it as
require_account; _try_refresh_nous_client_credentials refuses any
replacement whose `sub` differs (logged at INFO, current key kept). A key
with no `sub` is not adopted proactively at all. The reactive 401 path is
unchanged, and same-account adoption (the keepalive's or a peer's fresh key)
still works.

Verified with the reviewer's own live probe (real AIAgent -> real
prepare_iteration -> real auth.json transaction -> real OpenAI SDK ->
loopback capture): explicit-account case account-A -> account-A,
adopted_fresh=False (was A -> B); same-account still adopts; 12 concurrent
near-expiry agents still 0 x 401.

Tests (2 new): a fresh key for a different account is never adopted; a key
without an account claim is left alone without touching the store.

Subject: [PATCH 016/276] fix(delegation): an interim task-failure notice never
 claims, acknowledges or dedups against the batch's final result

Independent review of the first version reproduced a final-result loss with
real dispatch, SQLite claims and the delivery consumers: the interim notice
carried the batch's delegation_id and every consumer claims and acknowledges
durable rows by that id alone. A busy parent that drained the notice first
acknowledged the FINAL result's row; the consolidated result could then
never be claimed, and would not replay after restart. The gateway's
in-memory dedup keyed on (type, delegation_id) and suppressed the final
(and every sibling notice) the same way.

The notice is now recognised as a non-durable event at both boundaries:
claim_event_delivery returns the empty token for it (is_interim_delegation_event),
the gateway preflight does not claim the durable row for it, and the
gateway dedup identity carries the task index so notices are distinct from
the final and from each other (the TUI key already did).

Reviewer's own probe re-run on this head: gateway receives
['notice', 'notice', 'final'] (was ['notice']); busy-parent case: the notice
takes no claim token, the final's claim succeeds and its row stays pending
until delivered (was: final claim None, row 'delivered' with an undelivered
result inside).

Tests (2 new): the notice is non-durable at the claim boundary; the gateway
identity separates two notices and the final into three.

Subject: [PATCH 018/276] fix(tools): truncation footers name the path the
 SANDBOX sees, not the host path (#72389, #81984, #77015)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

web_extract / browser_snapshot / delegate_task spill their full text under HERMES_HOME/cache,
which is mounted read-only into docker/modal (at /root/.hermes) and synced under ~/.hermes for
ssh/daytona/vercel — but the footer told the agent the HOST path, so read_file inside the
sandbox got 'File not found'. Translate through the existing
credential_files.to_agent_visible_cache_path (what tool_result_storage already does); local and
singularity are unchanged.

Salvaged from #72429 by @JonthanaHanh (the web_extract sites), widened to every footer.

Subject: [PATCH 021/276] fix(code-execution): remote kernels are keyed by
 their sandbox tool set (#97263)

The hermes_tools stub module a remote kernel imports is generated from sandbox_tools once,
at spawn, but the registry key was (owner, env_type, task_env_id) only: a later
execute_code call with a different tool set (skill loaded, toolset toggled) reused the
kernel and got stale stubs. The tool set is now part of the key; a different set gets
its own kernel and the over-cap eviction keeps the newest.

Subject: [PATCH 023/276] fix(delegation): summary headroom uses the
 aggregator's own prompt size; unknown usage means the static ceiling, never
 zero context

Independent review found two holes in the first fix. A parent with no usage
row yet was treated as 0 tokens used, so a 190K/200K prompt received a
384K-char dynamic summary budget instead of ~4K; the budget now returns None
(static ceiling only) when nothing is known. And under MoA the folded usage
includes advisor prompts that are not in the parent's context, over-stating
the prompt size and wrongly truncating summaries; turn_usage now records the
aggregator's pre-fold prompt_tokens as _last_prompt_size_tokens and the
budget reads that first.

Tests (2 new): unknown usage -> None; MoA-folded and unfolded parents with
the same real prompt get the same budget.

Subject: [PATCH 024/276] chore(models): OpenRouter and Nous pickers drop the
 undated deepseek-v4-flash in favor of the 0731 snapshot

The bare deepseek/deepseek-v4-flash slug is the pre-snapshot release; both
aggregators now carry deepseek-v4-flash-0731 (and Nous exposes the rolling
~deepseek/deepseek-v4-flash-latest alias). Keeping both rows in the curated
picker just duplicates the flash tier.

- OPENROUTER_MODELS (derives the nous list): drop deepseek/deepseek-v4-flash
- model-catalog.json regenerated

Deliberately KEPT: alibaba-token-plan / opencode-go / commandcode / deepseek
direct plugin fallback_models + default_aux_model (bare id is the wire slug
those providers serve), DEFAULT_CONTEXT_LENGTHS / reasoning floor / pricing
snapshot entries (manually-typed id still behaves), and the
deepseek-chat/deepseek-reasoner -> deepseek-v4-flash alias normalization.

Subject: [PATCH 025/276] fix(goal): the TUI judge also sees only its own
 session's processes; a lifted barrier resumes the loop from the idle hook

Independent review found two gaps in the first fix. The TUI/Desktop/dashboard
goal path (tui_gateway/prompt_turn.py) still passed every agent's processes to
the judge; it now filters by the session's own key like the CLI and gateway
loops. And the 30-minute barrier cap (and a pid/timer barrier lifting at all)
was only checked lazily, on the next turn, so a parked session with nothing
else arriving stayed parked. The CLI idle hook now checks the barrier every
5 s while idle and queues the goal's continuation the moment it lifts.

Tests (2 new): an elapsed timed barrier queues the continuation from the idle
hook and clears the barrier; an unparked or inactive goal is a no-op.

Subject: [PATCH 026/276] fix(goal): the judge can WAIT on delegated subagents
 (4 of 5 nudges in one run re-poked an agent that was waiting on workers)

JUDGE_SYSTEM_PROMPT allowed WAIT only for "a background process listed
below" or a stated backoff. A fan-out orchestrator's in-flight work is
delegated subagents, which are not registry processes, so when the agent
said "waiting on 4 worker batches, nothing to dispatch" the judge answered
CONTINUE ("no background process is listed to gate on"). In the
1,393-agent run 4 of 5 nudges fired 6-153 s after exactly such a turn and
each bought a status recap: 19 API calls at ~450K context, ~$4.9, and no
work a batch-complete notification would not have produced.

The judge now receives an "Active delegations: N batch(es) still running"
line (count of live async_delegation records whose parent_session_id is
this session, via the existing _session_records selector) and a WAIT
branch for it: wait_for_seconds 600-1800 when the response says it is
waiting on them with nothing dispatchable. Both goal-loop callers (CLI,
gateway) pass the count.

Live A/B with the real auxiliary judge on the run's response shape
("4 worker batches still running ... nothing else is dispatchable until
these return"): main 3/3 CONTINUE, branch 3/3 WAIT 1200 s.

Tests (2): the prompt carries the delegations line only when N > 0 and
a wait verdict parses through; count_active_delegations is scoped to the
spawning session and ignores completed records.

Subject: [PATCH 027/276] fix(goal): a delegation WAIT lifts as soon as a batch
 returns; the TUI passes the delegation count too

Independent review found the delegation WAIT was a plain timer: the batch
results arrived with 1,199 s left on a 1,200 s wait and nothing re-judged,
so integration sat unfinished until the timer ran out. The wait now records
how many batches it was set for (GoalState.waiting_on_delegations) and
is_waiting() lifts it the moment fewer are live, so the next idle tick
resumes with the result in hand. A plain timed wait (no delegations) is
unchanged. The TUI/Desktop goal path now passes the live delegation count
to the judge like the CLI and gateway do.

Live with the real auxiliary judge: WAIT 900 s with 4 live batches; one
returns -> is_waiting() False immediately.

Test: parked with 4 live, lifted at 3, plain timed wait unaffected.

Subject: [PATCH 028/276] fix(delegation): validate
 compression_threshold_tokens; state that it caps the trigger, not the payload

Independent review: a YAML `true` coerced to int 1 and gave every child a
one-token compression trigger; "200k" silently disabled the default cap.
Values are now validated: an int >= 16000 is used, 0/false/null disable on
purpose, anything else warns and falls back to the 200K default so a typo
never costs money. Config comment and docs say it caps the compaction
trigger, not a hard request-size limit.

Test: true / "200k" / 5 -> default; 0 / false / None -> disabled; valid ints
pass.

 When `base_url` points at an Anthropic-compatible endpoint — for example a path ending in `/anthropic`, an Azure Foundry Claude route, or a MiniMax `/anthropic` proxy — `api_mode` is auto-detected as `anthropic_messages` so the subagent uses the right wire format without you setting anything.

It is independent of the parent's own threshold and caps the compaction *trigger*, not the request payload. Accepted values: a token count of at least 16000, or `0` to disable the subagent-specific cap; anything else (a bare `true`, `"200k"`) is a config error that falls back to the default with a warning.
 
 `delegation.request_overrides` works on **all three** resolution branches — direct `base_url`, named `provider`, and pure inherit — so it always takes effect. Top-level keys are API kwargs (e.g. `service_tier`); an `extra_body` sub-dict is merged into the request's `extra_body`. Explicit values merge **over** runtime- or parent-derived overrides: explicit top-level keys win, and `extra_body` is deep-merged one level, so a provider's own request personality (e.g. `thinking: {type: disabled}`) survives unless your key redefines it. See [Configuration → Delegation](../configuration.md#delegation) for details.

Subject: [PATCH 029/276] fix(terminal): promotion keeps the shell-detachment
 refusal; the note only promises a notification the session can receive

Independent review: an over-cap timeout on `cmd &` was promoted, so the
tracked shell exited at once while the payload ran untracked (the exact
thing the '&' guidance exists to prevent); and the note promised a
notification even on finite sessions where async delivery is disabled and
the spawn had already cleared notify_on_complete. The detachment guidance
now runs before the promotion decision regardless of timeout, and the note
reads the spawn's actual notify_on_complete: notification wording when kept,
poll-only wording when the session cannot receive one.

Tests (2 new): '&' and nohup with an over-cap timeout still refuse; the note
matches the delivery capability.

Subject: [PATCH 030/276] fix(terminal): every Windows drive letter is a host
 cwd, not just C: (#60962)

_HOST_CWD_PREFIXES only listed C:\ and C:/, so a D:\ or E:/ working directory on a
Windows host reached docker run -w and the container started in a directory that does
not exist. The two prefix scans now go through one _is_host_cwd predicate that matches
any drive letter with either slash.

path. The warning now names the reason: 'not found on this host' vs 'denied by the
delivery policy'.

Subject: [PATCH 034/276] fix(file_tools): the rewrite hint reads through the
 task's backend, skips non-regular and oversized files, and compares in linear
 time

Independent review: the hint read the HOST path even for remote/sandbox
backends (a different file), blocked forever on a host FIFO while holding
the write lock, and used SequenceMatcher, which is quadratic on repeated
lines (a 460 KB same-line file took ~22 s). It now reads the old content via
the task's file ops read_file_raw (regular files only, correct backend),
skips files above 400 K chars, and compares line multisets (Counter
intersection, linear).

Reviewer's own probe on this head: 460 KB repeated-line file 22.3 s -> 0.0 s
(skipped), 230 KB 46 ms, remote backend gets no host-derived hint, FIFO write
returns at once.

Subject: [PATCH 035/276] fix(goal): the re-paste pointer applies only to a
 near-whole re-paste, and on every surface

Independent review: substring matching lost the selected objective (after a
message offering API or UI work, '/goal ship the API' and '/goal ship the UI'
kicked identically), and the gateway and TUI /goal paths still re-sent the
full goal. The rule now lives once in hermes_cli.goals.goal_kick_prompt:
the pointer replaces the goal only when the goal is >= 400 chars, contained
in the last user message, and >= 80% of it. The CLI reads the last user
message from its history; the gateway and TUI read it from the SessionDB
(fail-safe: goal sent verbatim).

Tests: a fragment that selects one option is kicked verbatim; a long goal
that is a minority of a longer message is kicked verbatim; all three
surfaces call the shared function.

Subject: [PATCH 037/276] fix(tools): a sandbox that cannot run commands is
 'environment unavailable', not 'File not found' (#44750)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_probe_regular_file returned 'missing' for ANY non-zero exit, so a docker container that
was still starting, paused, or otherwise unable to exec made read_file / read_file_raw /
read_file_bytes report a false 'File not found' — which the model then trusted for the
rest of the session. The probe now echoes a sentinel for a genuinely missing path and a
non-zero exit without either sentinel is reported as an environment failure with a retry
hint; search_files does the same when its existence probe returns neither marker.

Subject: [PATCH 040/276] fix(serve): Desktop-over-SSH isolated backends retire
 themselves when no client is connected (#101626)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

serve --isolated is detached on purpose (setsid/nohup, PPID 1) so it survives the SSH
channel closing, and every teardown path lived on the client. A laptop that sleeps
mid-session (dark wake reconnects the tunnel, spawns a backend, sleeps again) therefore
left a new backend behind every cycle, each one an extra writer on state.db — the
multi-writer source behind the WAL corruption incidents.

Only for backends started with --ssh-session-token-file: an ASGI wrapper counts accepted
WebSocket sessions on every dashboard route without touching the handlers; a watchdog
requests a graceful uvicorn exit (WAL checkpoint, exit 0) once no client has been
connected for dashboard.ssh_isolated_idle_grace_s (default 15 min) AND no agent turn is
running. An unreadable turn state fails closed (the backend stays up). Loopback normally
disables the WS ping, but across a tunnel the local socket stays healthy while the far
end sleeps, so these backends keep a slow ping (60s / 10 min) that a GIL-holding turn
cannot trip.

Design, client-count/turn-probe/fail-closed shape and the tunnel-ping rationale from
#101678 by @StanleyStetson; this is the slim redo on the decomposed web server (no
exclusive home lock / handover protocol — the newcomer never needs to evict an idle
incumbent once idle incumbents exit on their own).

 - `trusted_proxies` — IP addresses or bounded CIDR networks allowed to supply `X-Forwarded-Proto` and `X-Forwarded-For`. Loopback remains trusted automatically. Configure this when the TLS reverse proxy connects from another container or host. Prefer the proxy's exact IP; use a small dedicated network only when its address is dynamic. Wildcards and `/0` networks are rejected.
 - `oauth` / `basic_auth` / `drain_auth` — auth provider config read by the bundled dashboard-auth plugins. The drain secret itself is **not** set here; it's provisioned via the `HERMES_DASHBOARD_DRAIN_SECRET` env var. See [Web Dashboard](/user-guide/features/web-dashboard) for full auth setup.
 - `ws_ping_interval` / `ws_ping_timeout` — WebSocket keepalive tuning for non-loopback binds (loopback connections never ping). Raise these on high-latency links (Tailscale, distant SSH tunnels) where the 20 s defaults can manufacture spurious 1006 disconnects.
+- `ssh_isolated_idle_grace_s` (default `900`) — a Desktop-owned `hermes serve --isolated` backend reached over SSH is detached from the SSH session on purpose, so a laptop that sleeps mid-connection cannot tear it down; each dark-wake reconnect used to leave another backend holding `state.db`. The backend now retires itself once no client WebSocket has been connected for this long and no agent turn is running (a turn keeps it alive; an unreadable turn state keeps it alive too). Set high if you rely on a detached backend finishing long work after the laptop sleeps. Such backends also send a slow WebSocket ping (60 s, 10 min timeout) so a half-open tunnel is noticed.
 - `ws_orphan_reap_grace_s` — how long a WS-detached session waits before the orphan reaper collects it. Raise alongside the keepalive values if clients reconnect slowly. (`HERMES_TUI_WS_ORPHAN_REAP_GRACE_S` remains as an internal override.)
 - `ws_orphan_activity_stale_s` (default `600`) — how long a detached **running** turn's activity clock (the same clock the `agent.turn_liveness` watchdog samples: API waits, stream tokens, tool heartbeats) must be idle before the orphan reaper interrupts it. A client-absent turn that is still actively producing keeps running to completion detached — closing the laptop, backgrounding the mobile app, or a desktop update no longer cancels healthy long turns; only a genuinely wedged turn is interrupted. Set `0` to interrupt at the grace window regardless of activity (old behavior).
 - `startup_orphan_sweep` (default `true`) — the WS-orphan reap timer above is in-process, so a gateway restart (update, crash, systemd) before it fires leaves the session row open forever — phantom "active" work in `/resume` and dashboards. On every gateway boot — both the stdio TUI (`entry.main`) and the desktop/dashboard WebSocket sidecar (`handle_ws`) — rows with source `tui` / `desktop` / `subagent` whose start time **and** newest message are both older than the session TTL (`HERMES_TUI_SESSION_TTL_S`, default 6 hours) are closed with `end_reason: startup_orphan_reap`. Messaging-platform sessions (Telegram, Discord, …) are never touched, live in-memory sessions (a client that already resumed) are excluded, and swept sessions remain resumable.

Subject: [PATCH 043/276] fix(file_sync): Windows sync_back no longer drops
 remote edits (#76267)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two stacked Windows-only failures in FileSyncManager.sync_back:

1. The staging tar was a NamedTemporaryFile held open while the backend's
   bulk_download_fn reopened the same path for writing — PermissionError on
   Windows (exclusive handle). mkstemp + close + unlink in finally instead.
2. Staged member keys came from os.path.relpath and mapping parents from
   Path(remote).parent — both stringify with backslashes on Windows, so no
   staged file ever matched its POSIX remote key and every edit was skipped
   as "no host mapping". Keys are now built with as_posix(); parents with
   posixpath.dirname; the inferred host path is joined with the host's Path.

(cherry picked from commit e8cab109db, re-applied on the current file)

Subject: [PATCH 045/276] feat(docker): terminal.docker_snap_compat opt-out for
 snap-packaged Docker under AppArmor (#9730)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On hosts where Docker ships as a snap (Ubuntu cloud images / Azure VMs), the
snap's AppArmor confinement turns two sandbox hardening flags into a dead
container at start: `--init` fails with "exec /sbin/docker-init: operation not
permitted" and `--security-opt no-new-privileges` then fails every exec the
same way ("exec /usr/bin/sleep: operation not permitted"). This is snapd
LP#1908448 — not probeable from the client, and docker_extra_args cannot remove
flags we add.

`terminal.docker_snap_compat: true` drops exactly those two flags; cap-drop ALL,
the tmpfs hardening, PID limits and the privdrop caps are unchanged, and a
warning is logged at container start. Bridged everywhere the other docker_*
keys are (CLI env map, gateway env map, `hermes config set` sync, terminal_tool
env read, the shared container_config shaper, DEFAULT_CONFIG).

+### Snap-packaged Docker (AppArmor)
+
+On hosts where Docker was installed as a snap (common on Ubuntu cloud images, e.g. Azure VMs), the snap's AppArmor confinement rejects two of the sandbox's hardening flags and the container dies at start:
+
+```
+exec /sbin/docker-init: operation not permitted     # --init
+exec /usr/bin/sleep: operation not permitted        # --security-opt no-new-privileges
+```
+
+This is a snapd limitation ([LP#1908448](https://bugs.launchpad.net/snapd/+bug/1908448)), not something Hermes can probe around. Either install Docker from Docker's apt repository instead of the snap (preferred — all hardening stays on), or opt in:
+
+```yaml
+terminal:
+  docker_snap_compat: true   # drops --init and no-new-privileges; cap-drop, tmpfs, PID limits stay
+```
+
+With it on, zombie processes inside the sandbox are not reaped by an init and a setuid binary inside the container can regain privileges; a warning is logged at container start.
+
 ### Optional: Mount the Launch Directory into `/workspace`
 
 Docker sandboxes stay isolated by default. Hermes does **not** pass your current host working directory into the container unless you explicitly opt in.

Subject: [PATCH 048/276] fix(docker): teardown workers of reaper-detached
 containers are drained at exit (#86317)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

DockerEnvironment.cleanup() runs docker stop + docker rm -f on a daemon thread and
keeps the handle on the env. The idle reaper pops the env out of _active_environments
BEFORE calling cleanup(), and the atexit drain only iterated that registry — so a
detached env's worker was unreachable and died with the interpreter, leaving a
stopped (or, if the exit came fast enough, still running) labeled container behind
while the log said the environment was cleaned.

Every teardown worker is now also recorded in a module-level set in docker.py;
_atexit_cleanup joins that set after the registry pass via
DockerEnvironment.wait_for_all_teardowns (re-snapshotting each pass, since the
reaper can start a worker while the drain runs). Finished workers are dropped from
the set on each drain so it cannot grow across a long gateway life.

Mechanism from #86344 by @PRATHAMESH75; this is the slim redo — one shared set
plus one static drain hooked into the existing terminal_tool atexit, instead of a
second atexit registration in docker.py.

evals/postmortem/ turns the one-off audit behind tracking issue #103563 into
something anyone with a Hermes state.db copy (and optionally rotated
agent.log*) can run on their own fan-out:

  forensics/   common.py discovers the run tree (root = most descendants,
               compression-rollover children excluded so cost buckets stay
               disjoint), fits pricing from estimated_cost_usd, and five lanes
               recompute the OBSERVED figures: tokens (buckets, depth/duration
               shares, context reconstruction, excess-cache-write proxy, cap
               replay), logcalls (per-call cache behaviour from agent.log with
               coverage printed first; strict and loose plateau definitions
               reported separately), delegation (timeouts, orphaned children,
               polling hours, batch-join withheld child-hours, truncated
               summaries), tools (hardline blocks, foreground refusals,
               whole-file rewrites), goal_loop (nudges, parked barrier), rework
               (public-surface drop at PR open + post-open commit inventory).
               Every figure is labeled OBSERVED or MODELED.
  live_ab/     the per-PR A/Bs (real code paths, fake providers, temp
               HERMES_HOME), paths from argv.
  review_probes/ the independent /review's probes, credited and adapted; each
               reproduced a round-1 defect and the fixed head must pass it.
  run.py       runs the offline probes against one or two checkouts and prints
               PASS/FAIL side by side (--live adds the ones that spend cents).
  tests/       synthetic-DB smoke test for the lanes and runner.

On the run's DB the lanes reproduce the tracking issue's population exactly
(1,394 sessions, 93,284 calls, $19,302.59; cache_write $11,159.76) and on
main vs an integration checkout of the 13 PRs the runner shows every probe
FAIL -> PASS (two guard-only probes pass on both, noted in run.py).

The trajectories are deliberately not shipped: the DB holds 51,956 home
paths, 5,341 e-mails, private IPs, chat ids and real-shaped credentials in
tool output. The lane reports and recomputed JSON are in a secret gist
linked from #103563.

+# Post-mortem harness: forensics + live A/B for the 1,393-agent run fixes
+
+The scripts that produced every number in tracking issue #103563 and the "Independent review
+(round 2)" sections of its 13 PRs. Two halves:
+
+- **`forensics/`** reads a *copy* of a Hermes `state.db` (plus rotated `agent.log*` and git) and
+  recomputes the *observed* figures for any run: where the money went, per-call cache behaviour,
+  nested-delegate timeouts, batch-join delivery delay, tool friction, `/goal` loop behaviour, and the
+  post-open rework inventory. It needs no model calls and no network.
+- **`live_ab/`** and **`review_probes/`** exercise the real code paths of a checkout (real
+  `AIAgent`, dispatch, judge, scanner, SDK) against local fake providers to show what each fix
+  *does*. `run.py` runs them against one or two checkouts and prints PASS/FAIL side by side.
+  `review_probes/` are the probes the independent `/review` wrote; each reproduced a defect in the
+  first version of a PR and the fixed head must pass it.
+
+Everything is labeled **OBSERVED** (from usage rows / logs / git) or **MODELED** (a reconstruction or
+replay). Do not add the modeled figures to the observed ones; see §5 of #103563 for why they overlap.
+
+## Requirements
+
+- A Hermes checkout with its venv (`.venv/bin/python`). NeMo Relay is not required for the forensics;
+  it is what the run itself used for the wire captures in `live_ab/cache_prefix_wire.py`.
+- For forensics: a **copy** of `~/.hermes/state.db` (never point at the live file; `sqlite3 state.db ".backup copy.db"`
+  or `cp` while Hermes is idle) and, optionally, the rotated `~/.hermes/logs/agent.log*`.
+- For `--live` probes: real credentials in `HERMES_HOME` (they spend cents per run).
+
+## Forensics: recompute the observed numbers for YOUR run
+
+```bash
+cd <hermes-checkout>
+P=.venv/bin/python
+# 1. cost buckets, depth/duration shares, context-size reconstruction, excess-cache-write proxy, cap replay
+$P -m evals.postmortem.forensics.tokens     --db state_copy.db [--root <session_id>] [--cap 200000 --floor 65000]
+# 2. per-call cache behaviour from the logs (coverage fraction is printed first; quote nothing without it)
+$P -m evals.postmortem.forensics.logcalls   --db state_copy.db --logs "$HOME/.hermes/logs/agent.log*"
+# 3. delegation: timeouts, orphaned children, polling, batch-join delay, truncated summaries
+$P -m evals.postmortem.forensics.delegation --db state_copy.db
+# 4. tool friction: hardline false blocks, foreground refusals, whole-file rewrites, output volume
+$P -m evals.postmortem.forensics.tools      --db state_copy.db
+# 5. /goal loop: nudges, parked barrier, notification counts
+$P -m evals.postmortem.forensics.goal_loop  --db state_copy.db
+# 6. rework inventory for a large PR (git only)
+$P -m evals.postmortem.forensics.rework     --repo . --base <merge-base> --open <sha-at-open> --head <merged-sha>
+```
+
+Each writes `postmortem_out/<lane>.json` and prints a summary. `--root` defaults to the top-level
+session with the most descendants; compression-rollover children are excluded from the population so
+cost buckets are disjoint. Pricing is fitted from `estimated_cost_usd`, so dollars match what that
+Hermes recorded (an estimator, not an invoice).
+
+### Reference output (the #102117 run, `state_copy.db` of 2026-09-04)
+
+| lane | prints |
+|---|---|
+| tokens | `1394 sessions, $19,302.59`; buckets cache_write $11,159.76 · cache_read $3,587.17 · output $4,555.48; depth-2 65%; >60 min 61%; MODELED excess cache-write proxy ~$9.1k; sawtooth cap 200K: prompt volume ×0.76 (reconstructed sizes) |
+| logcalls | coverage 22,489/93,284 (24.1%); median prompt 229,648, p90 408,794, >200K 59%; hit ratio 93.9%; strict plateau 22.5% of uncached input, non-advancing 74.8%; sawtooth cap 200K on real sizes ×0.498 |
+| delegation | 266 orchestrators; 332 delegate_task timeouts in 234 sessions (all nested); 93 results carried; 242.6 h sleep after first timeout; those sessions' lifetime $4,034.69 (includes real work); summaries truncated 123/220; batch-join withheld child-hours root 233 / depth-1 300 / depth-2 52 |
+| tools | 96,855 tool calls; hardline blocks 579 (566 "malformed" class); foreground timeout refusals 475 (303 asked 900 s); `&` 185, nohup 24; write_file 8,188 calls / 92.8M chars, 661 rewrites of a file read this session >20k; patch 4,623 |
+| goal_loop | 5 nudges (2 within 180 s of a "waiting" turn); 34 batch notices; 48 bg-process notices; final barrier `waiting_on_session=proc_…` parked 201 min |
+| rework | surface at open: 1,703 names / 341 modules, 951 methods / 156, 126 test defs / 52 files; 125 post-open commits (simplify 55, review-fix 39, fix 19, …) |
+
+The two sawtooth figures differ on purpose: `tokens` replays *reconstructed* per-call sizes for all
+93k calls (×0.76); `logcalls` replays *real* per-call sizes for the 24% of calls in the logs (×0.50,
+the peak-concurrency window). The tracking issue quotes the second and says so.
+
+## Live A/B: what each fix does
+
+```bash
+# offline probes (fake providers, temp HERMES_HOME), main vs a branch or integration checkout:
+.venv/bin/python -m evals.postmortem.run --repo /path/to/main --compare /path/to/branch
+# add the probes that make real provider calls (cents):
+.venv/bin/python -m evals.postmortem.run --repo /path/to/branch --live
+# one PR only:
+.venv/bin/python -m evals.postmortem.run --repo . --only 103492
+```
+
+| probe | PR | expects on the fixed head |
+|---|---|---|

+
+## What is NOT here, and why
+
+- **The trajectories themselves.** The run's `state.db` contains 51,956 absolute home paths, 5,341
+  e-mail addresses, private IPs, chat/user ids, and real-shaped API keys and JWTs in tool output. It
+  is not publishable, and this harness is written so it does not need to be: run it on your own DB.
+- **Hand classification.** The root-cause classes of the 72 rework commits (dropped symbol vs semantic
+  drift vs compat fallout) were labeled by hand in the original audit; `forensics/rework.py` reproduces
+  the mechanical inventory that labeling started from and stops there.
+- **A single aggregate saving.** By design. Each lane prints its own number with its own caveat.
+
+## Evidence bundle
+
+The original lane reports, the independent review, and the JSON this harness recomputes on the run's DB
+are in a secret gist linked from #103563 (no trajectories; see "What is NOT here").
+
+## Provenance
+
+Forensic lanes: five parallel Hermes subagents (2026-09-04), rewritten here to take `--db`/`--root`
+instead of hard-coded paths. `live_ab/`: the primary agent's per-PR A/Bs. `review_probes/`: the
+independent `/review` subagent's probes (2026-09-05), adapted to take paths from the command line;
+their findings and the fixes are in each PR's "Independent review (round 2)" section.

+"""Shared loaders for the post-mortem forensics: point at ANY Hermes ``state.db`` (a copy, never the live

+Nothing here knows about a particular run. The root is discovered as the session with the most
+descendants unless ``--root`` is given; compression-rollover children (a child whose ``id`` the parent's
+``compaction`` metadata names as its continuation) are excluded from the tree so cost populations stay

+    ... INFO [<session_id>] agent.conversation_loop: API call #N: model=... in=<prompt> out=<out> total=... latency=..s cache=<hit>/<total>
+
+Given the rotated logs, this reproduces: prompt-size distribution, cache hit-ratio buckets, the
+"plateau" signature of a broken cache prefix (hit count stuck at the previous call's breakpoint while
+``in`` grows), the share of uncached input those plateaus explain, and the sawtooth replay of an absolute
+context cap on REAL per-call prompt sizes (the figure the tokens lane reported as -49%).
+
+    python -m evals.postmortem.forensics.logcalls --db state_copy.db --logs ~/.hermes/logs/agent.log*
+
+Coverage caveat: logs rotate; report the fraction of the run's calls that were found before quoting
+anything from this lane, and treat extrapolations as upper bounds.

Subject: [PATCH 051/276] fix: mid-turn user message no longer waits behind a
 foreground terminal command
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A message typed while the agent runs (CLI busy_input_mode=interrupt, gateway
priority redirect, ACP redirect) goes through AIAgent.redirect(). During tool
execution redirect() degrades to steer(), whose delivery rides the tool result
— so a long foreground command (a `sleep 285` CI poller, a build) parked the
user's message until it exited. The UI printed "Redirected current turn" while
nothing happened for minutes.

redirect() now also asks the tool workers to YIELD (tools/interrupt.request_yield).
The local terminal backend's wait loop honours it: the drain thread is stopped, the
still-running Popen is adopted by the process registry as a notify_on_complete
background session (ProcessRegistry.adopt_local — output so far seeds the buffer,
the registry reader continues from the pipe), and the tool returns immediately with
status "yielded_to_background" + session_id. The command is never killed; the
completion notification arrives as usual and process(poll/wait/log/kill) work on it.

Non-local backends and internal env.execute() consumers pass no yield_handler and
are unaffected; a stale yield bit is cleared with the interrupt bit per worker tid.

Subject: [PATCH 052/276] feat(skills): reddit-reading and rss-feeds bundled
 skills, multi-platform sweep guidance

Two zero-install research skills plus routing guidance, ported as ideas
(not code) from the Agent Reach skill's per-platform backend routing.

reddit-reading (skills/social-media): subreddit listings, site/subreddit
search, threads with comments, user pages. Live-verified from a datacentre
IP: www .json, api.reddit.com, old.reddit, r.jina.ai and the browser tool
all return 403 / an empty shell / a humanity check; the Atom .rss endpoints
are the only anonymous path and are throttled to ~1 request/min/IP. The
script waits out the x-ratelimit-reset window once and retries, and
switches to the OAuth API (scores, nested comments, ~100 req/min) when
REDDIT_CLIENT_ID/SECRET are present. `doctor` reports the active backend.

rss-feeds (skills/research): RSS 2.0 / RSS 1.0 / Atom / JSON Feed parsing
with UTC-normalised dates, --since/--limit, and feed discovery behind a
page URL (<link rel=alternate>, then well-known paths). Stdlib only; the
optional blogwatcher skill remains the stateful many-feed reader and now
points at this one for one-off reads.

grounded-citations gains a "Multi-Platform Sweeps" section routing
"what are people saying about X" tasks across web, Reddit, feeds, video,
code and X with per-platform attribution and coverage-gap reporting;
competitor-news-monitor references the new sources.

Tests: two invariant tests per skill (format normalisation + discovery;
anonymous 429 handling + OAuth routing/flattening), no network. The
reddit test caught a real bug: the feed footer's "/u/author" leaked into
post bodies.

+# RSS Feeds Skill
+
+Reads any RSS 2.0, RSS 1.0/RDF, Atom, or JSON Feed URL into a clean, date-sorted list of
+entries, and discovers the feed behind an ordinary page URL (`<link rel="alternate">` or
+the usual `/feed`, `/rss.xml`, `/atom.xml` paths). Standard library only, nothing to
+install. It does not fetch full article bodies — pass an entry's link to `web_extract` for
+that.
+
+## When to Use
+
+- "What's new on <blog/site>", "latest releases of <GitHub repo>", "recent posts in
+  <subreddit>", "read this feed", "does this site have an RSS feed".
+- Building a recurring digest with `cronjob_manage` (feeds are cheaper and more stable than
+  scraping the HTML front page every run). For a persistent read/unread database across
+  many feeds install the optional `blogwatcher` skill; this skill is the zero-install read.
+- Anything where a structured list of `title / link / date / author / summary` beats a
+  rendered page: podcasts, changelogs, YouTube channels, newsrooms, forum categories.
+
+## Prerequisites
+
+None. Python 3.10+, network access to the feed host.
+
+## How to Run
+
+Run through `terminal` with the skill-relative script path:
+
+```bash
+python3 scripts/feed.py read https://hnrss.org/frontpage --limit 10
+python3 scripts/feed.py read https://simonwillison.net/            # page URL → discovers the feed
+python3 scripts/feed.py read URL --since 2026-09-01 --json          # only newer entries, machine-readable
+python3 scripts/feed.py discover https://example.com/               # list candidate feed URLs
+```
+
+## Quick Reference
+
+| Source | Feed URL pattern |
+|---|---|
+| GitHub releases / commits / tags | `https://github.com/OWNER/REPO/releases.atom`, `…/commits/BRANCH.atom`, `…/tags.atom` |
+| Subreddit / Reddit search | `https://www.reddit.com/r/NAME/.rss`, `https://www.reddit.com/search.rss?q=…` (1 req/min anon; see `reddit-reading`) |
+| YouTube channel | `https://www.youtube.com/feeds/videos.xml?channel_id=UC…` |
+| Hacker News | `https://hnrss.org/frontpage`, `https://hnrss.org/newest?q=TERM` |
+| arXiv category | `https://rss.arxiv.org/rss/cs.CL` |
+| Substack / Medium / WordPress / Ghost | `SITE/feed`, `medium.com/feed/@user`, `SITE/rss/` |
+| Podcasts | the show's RSS URL from its hosting page (`discover` finds it) |
+
+Output fields per entry: `title`, `link`, `published` (UTC ISO 8601), `author`, `summary`
+(HTML stripped, ≤ 2000 chars). Entries are sorted newest-first.
+
+## Procedure
+
+① If you only have a site URL, run `read` on it directly; the script discovers the feed
+and reports which URL it used (`discovered_from`). Use `discover` when you want to choose
+between several advertised feeds (comments feed vs posts feed, per-category feeds).
+
+② Bound the request: `--limit` for "latest N", `--since YYYY-MM-DD` for "since last
+check". For a cron digest persist the last-seen `published` value and pass it as
+`--since` next run.
+
+③ For full text, hand the entry `link` to `web_extract`; feed summaries are frequently
+truncated or the first paragraph only.
+
+④ Cite the entry `link`, not the feed URL, when the result feeds a report
+(`grounded-citations`).
+
+## Pitfalls
+
+- A 200 response with HTML means the URL is a page, not a feed; the script falls through
+  to discovery automatically, but a site with no `<link rel="alternate">` and none of the
+  common paths reports `no feed found` — check the site's footer or `/sitemap.xml` before
+  concluding there is none.
+- Reddit feeds share Reddit's anonymous throttle (about one request per minute per IP).
+  Chain them through `reddit-reading`, which waits out the window, when you need more
+  than one Reddit call.
+- Dates: RSS `pubDate` is RFC 822 and Atom uses ISO 8601; the script normalises both to
+  UTC. Feeds that omit dates sort to the bottom and are dropped by `--since`.
+- Some feeds are Cloudflare-fronted and 403 non-browser clients; `blocked-page-recovery`
+  handles that class.
+
+## Verification
+
+`python3 scripts/feed.py read https://github.com/NousResearch/hermes-agent/releases.atom
+--limit 1` prints one entry with a `releases/tag/` link and a `[atom]` format tag;
+`discover https://simonwillison.net/` prints an `/atom/` URL.

+# Reddit Reading Skill
+
+Reads Reddit content — subreddit listings, site or subreddit search, full threads with
+comments, and user activity — from a server or headless machine where the normal routes
+are dead. It does not post, vote, or log in as a user. Idea credit: the per-platform
+backend routing in [Agent Reach](https://github.com/Panniantong/Agent-Reach).
+
+## When to Use
+
+- "What is r/LocalLLaMA saying about X", "find Reddit threads on Y", "summarise this
+  Reddit thread", "what has u/someone posted lately".
+- Any `reddit.com` URL the user shares. `web_extract`, `browser_navigate` and the
+  `.json` endpoints all fail from server IPs (403 or a "Prove your humanity" wall);
+  this skill is the working path.
+- Not for posting, voting, messaging, or anything needing a user login.
+
+## Prerequisites
+
+None for the anonymous path. For anything beyond a handful of calls per task, create
+a free Reddit "script" app at https://www.reddit.com/prefs/apps and put the two values
+in `~/.hermes/.env`:
+
+```
+REDDIT_CLIENT_ID=...
+REDDIT_CLIENT_SECRET=...
+```
+
+The script picks the OAuth backend automatically when both are set (~100 requests per
+minute, scores, comment nesting, `num_comments`). Without them it uses Reddit's Atom
+feeds, which are the only unauthenticated endpoints still served to non-residential IPs.
+
+## How to Run
+
+Run every command through `terminal` with the skill-relative script path:
+
+```bash
+python3 scripts/reddit.py doctor                                  # which backend, current rate-limit window
+python3 scripts/reddit.py sub LocalLLaMA --sort hot --limit 15
+python3 scripts/reddit.py search "hermes agent" --sub LocalLLaMA --sort new
+python3 scripts/reddit.py thread https://www.reddit.com/r/x/comments/abc123/slug/ --limit 40
+python3 scripts/reddit.py user spez --limit 10
+python3 scripts/reddit.py --json search "topic"                  # machine-readable
+```
+
+## Quick Reference
+
+| Need | Command | Anonymous | OAuth |
+|---|---|---|---|
+| Subreddit front page | `sub NAME --sort hot\|new\|top\|rising [--time week]` | ✔ | ✔ |
+| Search all of Reddit | `search "q" --sort relevance\|new\|top\|comments` | ✔ | ✔ |
+| Search one subreddit | `search "q" --sub NAME` | ✔ | ✔ |
+| Thread + comments | `thread URL --limit N` | ✔ top-level only, no scores | ✔ nested, scores |
+| User posts/comments | `user NAME` | ✔ | ✔ |
+| Backend + rate limit | `doctor` | ✔ | ✔ |
+
+## Procedure
+
+① `doctor` once per task if you have not called it this session — it tells you which
+backend is live and how many seconds remain in the anonymous window.
+
+② Plan your calls before making them. Anonymous Reddit allows roughly **one request per
+minute per IP**; the script sleeps until the window resets on a 429 and retries once, so
+a five-call plan costs about five minutes. Prefer one `search --sub` over several `sub`
+listings, and read one thread rather than the whole listing.
+
+③ For "what is the community saying" questions, read the thread bodies (`thread`) rather
+than stopping at titles; the listing only carries the first ~300 characters of each post.
+
+④ Cite the permalink (`url` field), not the listing page, when the result feeds a report.
+`grounded-citations` registers these URLs like any other source.
+
+⑤ If the user needs sustained Reddit access (monitoring, more than ~10 calls), stop and
+ask them to add the OAuth credentials rather than grinding through the throttle.
+
+## Pitfalls
+
+- `www.reddit.com/…/.json`, `api.reddit.com` and `old.reddit.com` return 403 or an
+  empty "Welcome to Reddit" shell for datacentre IPs. Do not fall back to them; do not
+  spoof a browser User-Agent (also 403).
+- `r.jina.ai` and the `browser_navigate` tool hit the same block ("blocked by network
+  security" / humanity check). `blocked-page-recovery`'s Wayback route can still recover
+  an **old** thread that was archived; it cannot fetch fresh ones.
+- Anonymous thread feeds only contain the post plus top-level comments (Reddit caps the
+  feed at a handful of entries); scores and reply nesting are OAuth-only.
+- Reddit's `limit` on feeds is advisory — expect 5–25 entries regardless of what you ask.
+- Never paste `REDDIT_CLIENT_SECRET` into a chat or log; the script reads it from the
+  environment only.
+
+## Verification
+
+`python3 scripts/reddit.py doctor` prints `anonymous_feed: ok` and an
+`x-ratelimit-reset` value; `sub announcements --limit 1` returns one entry with a
+`reddit.com/r/announcements/comments/` URL. With credentials set, `doctor` prints
+`active_backend: oauth` and `thread …` output shows numeric scores.

+`web_search`. Fan out across source types, collect in parallel, then synthesise
+with every claim attributed to the platform it came from:
+
+| Source type | Route | What it adds |
+|---|---|---|
+| Open web | `web_search` → `web_extract` | official docs, articles, announcements |
+| Community discussion | `reddit-reading` (`search`, `thread`) | real user experience, complaints, workarounds |
+| Blogs / releases / changelogs | `rss-feeds` (`read`, `discover`) | dated primary posts, version history |
+| Video | `youtube-content` | walkthroughs, demos, talks |
+| Code | `terminal` with `gh search repos` / `gh search issues` | implementations, open bugs |
+| X/Twitter | `xurl` (needs API access) | announcements, developer chatter |

+
+# RSS Feeds Skill
+
+Reads any RSS 2.0, RSS 1.0/RDF, Atom, or JSON Feed URL into a clean, date-sorted list of
+entries, and discovers the feed behind an ordinary page URL (`<link rel="alternate">` or
+the usual `/feed`, `/rss.xml`, `/atom.xml` paths). Standard library only, nothing to
+install. It does not fetch full article bodies — pass an entry's link to `web_extract` for
+that.
+
+## When to Use
+
+- "What's new on &lt;blog/site>", "latest releases of &lt;GitHub repo>", "recent posts in
+  &lt;subreddit>", "read this feed", "does this site have an RSS feed".
+- Building a recurring digest with `cronjob_manage` (feeds are cheaper and more stable than
+  scraping the HTML front page every run). For a persistent read/unread database across
+  many feeds install the optional `blogwatcher` skill; this skill is the zero-install read.
+- Anything where a structured list of `title / link / date / author / summary` beats a
+  rendered page: podcasts, changelogs, YouTube channels, newsrooms, forum categories.
+
+## Prerequisites
+
+None. Python 3.10+, network access to the feed host.
+
+## How to Run
+
+Run through `terminal` with the skill-relative script path:
+
+```bash
+python3 scripts/feed.py read https://hnrss.org/frontpage --limit 10
+python3 scripts/feed.py read https://simonwillison.net/            # page URL → discovers the feed
+python3 scripts/feed.py read URL --since 2026-09-01 --json          # only newer entries, machine-readable
+python3 scripts/feed.py discover https://example.com/               # list candidate feed URLs
+```
+
+## Quick Reference
+
+| Source | Feed URL pattern |
+|---|---|
+| GitHub releases / commits / tags | `https://github.com/OWNER/REPO/releases.atom`, `…/commits/BRANCH.atom`, `…/tags.atom` |
+| Subreddit / Reddit search | `https://www.reddit.com/r/NAME/.rss`, `https://www.reddit.com/search.rss?q=…` (1 req/min anon; see `reddit-reading`) |
+| YouTube channel | `https://www.youtube.com/feeds/videos.xml?channel_id=UC…` |
+| Hacker News | `https://hnrss.org/frontpage`, `https://hnrss.org/newest?q=TERM` |
+| arXiv category | `https://rss.arxiv.org/rss/cs.CL` |
+| Substack / Medium / WordPress / Ghost | `SITE/feed`, `medium.com/feed/@user`, `SITE/rss/` |
+| Podcasts | the show's RSS URL from its hosting page (`discover` finds it) |
+
+Output fields per entry: `title`, `link`, `published` (UTC ISO 8601), `author`, `summary`
+(HTML stripped, ≤ 2000 chars). Entries are sorted newest-first.
+
+## Procedure
+
+① If you only have a site URL, run `read` on it directly; the script discovers the feed
+and reports which URL it used (`discovered_from`). Use `discover` when you want to choose
+between several advertised feeds (comments feed vs posts feed, per-category feeds).
+
+② Bound the request: `--limit` for "latest N", `--since YYYY-MM-DD` for "since last
+check". For a cron digest persist the last-seen `published` value and pass it as
+`--since` next run.
+
+③ For full text, hand the entry `link` to `web_extract`; feed summaries are frequently
+truncated or the first paragraph only.
+
+④ Cite the entry `link`, not the feed URL, when the result feeds a report
+(`grounded-citations`).
+
+## Pitfalls
+
+- A 200 response with HTML means the URL is a page, not a feed; the script falls through
+  to discovery automatically, but a site with no `<link rel="alternate">` and none of the
+  common paths reports `no feed found` — check the site's footer or `/sitemap.xml` before
+  concluding there is none.
+- Reddit feeds share Reddit's anonymous throttle (about one request per minute per IP).
+  Chain them through `reddit-reading`, which waits out the window, when you need more
+  than one Reddit call.
+- Dates: RSS `pubDate` is RFC 822 and Atom uses ISO 8601; the script normalises both to
+  UTC. Feeds that omit dates sort to the bottom and are dropped by `--since`.
+- Some feeds are Cloudflare-fronted and 403 non-browser clients; `blocked-page-recovery`
+  handles that class.
+
+## Verification
+
+`python3 scripts/feed.py read https://github.com/NousResearch/hermes-agent/releases.atom
+--limit 1` prints one entry with a `releases/tag/` link and a `[atom]` format tag;
+`discover https://simonwillison.net/` prints an `/atom/` URL.

+:::
+
+# Reddit Reading Skill
+
+Reads Reddit content — subreddit listings, site or subreddit search, full threads with
+comments, and user activity — from a server or headless machine where the normal routes
+are dead. It does not post, vote, or log in as a user. Idea credit: the per-platform
+backend routing in [Agent Reach](https://github.com/Panniantong/Agent-Reach).
+
+## When to Use
+
+- "What is r/LocalLLaMA saying about X", "find Reddit threads on Y", "summarise this
+  Reddit thread", "what has u/someone posted lately".
+- Any `reddit.com` URL the user shares. `web_extract`, `browser_navigate` and the
+  `.json` endpoints all fail from server IPs (403 or a "Prove your humanity" wall);
+  this skill is the working path.
+- Not for posting, voting, messaging, or anything needing a user login.
+
+## Prerequisites
+
+None for the anonymous path. For anything beyond a handful of calls per task, create
+a free Reddit "script" app at https://www.reddit.com/prefs/apps and put the two values
+in `~/.hermes/.env`:
+
+```
+REDDIT_CLIENT_ID=...
+REDDIT_CLIENT_SECRET=...
+```
+
+The script picks the OAuth backend automatically when both are set (~100 requests per
+minute, scores, comment nesting, `num_comments`). Without them it uses Reddit's Atom
+feeds, which are the only unauthenticated endpoints still served to non-residential IPs.
+
+## How to Run
+
+Run every command through `terminal` with the skill-relative script path:
+
+```bash
+python3 scripts/reddit.py doctor                                  # which backend, current rate-limit window
+python3 scripts/reddit.py sub LocalLLaMA --sort hot --limit 15
+python3 scripts/reddit.py search "hermes agent" --sub LocalLLaMA --sort new
+python3 scripts/reddit.py thread https://www.reddit.com/r/x/comments/abc123/slug/ --limit 40
+python3 scripts/reddit.py user spez --limit 10
+python3 scripts/reddit.py --json search "topic"                  # machine-readable
+```
+
+## Quick Reference
+
+| Need | Command | Anonymous | OAuth |
+|---|---|---|---|
+| Subreddit front page | `sub NAME --sort hot\|new\|top\|rising [--time week]` | ✔ | ✔ |
+| Search all of Reddit | `search "q" --sort relevance\|new\|top\|comments` | ✔ | ✔ |
+| Search one subreddit | `search "q" --sub NAME` | ✔ | ✔ |
+| Thread + comments | `thread URL --limit N` | ✔ top-level only, no scores | ✔ nested, scores |
+| User posts/comments | `user NAME` | ✔ | ✔ |
+| Backend + rate limit | `doctor` | ✔ | ✔ |
+
+## Procedure
+
+① `doctor` once per task if you have not called it this session — it tells you which
+backend is live and how many seconds remain in the anonymous window.
+
+② Plan your calls before making them. Anonymous Reddit allows roughly **one request per
+minute per IP**; the script sleeps until the window resets on a 429 and retries once, so
+a five-call plan costs about five minutes. Prefer one `search --sub` over several `sub`
+listings, and read one thread rather than the whole listing.
+
+③ For "what is the community saying" questions, read the thread bodies (`thread`) rather
+than stopping at titles; the listing only carries the first ~300 characters of each post.
+
+④ Cite the permalink (`url` field), not the listing page, when the result feeds a report.
+`grounded-citations` registers these URLs like any other source.
+
+⑤ If the user needs sustained Reddit access (monitoring, more than ~10 calls), stop and
+ask them to add the OAuth credentials rather than grinding through the throttle.
+
+## Pitfalls
+
+- `www.reddit.com/…/.json`, `api.reddit.com` and `old.reddit.com` return 403 or an
+  empty "Welcome to Reddit" shell for datacentre IPs. Do not fall back to them; do not
+  spoof a browser User-Agent (also 403).
+- `r.jina.ai` and the `browser_navigate` tool hit the same block ("blocked by network
+  security" / humanity check). `blocked-page-recovery`'s Wayback route can still recover
+  an **old** thread that was archived; it cannot fetch fresh ones.
+- Anonymous thread feeds only contain the post plus top-level comments (Reddit caps the
+  feed at a handful of entries); scores and reply nesting are OAuth-only.
+- Reddit's `limit` on feeds is advisory — expect 5–25 entries regardless of what you ask.
+- Never paste `REDDIT_CLIENT_SECRET` into a chat or log; the script reads it from the
+  environment only.
+
+## Verification
+
+`python3 scripts/reddit.py doctor` prints `anonymous_feed: ok` and an
+`x-ratelimit-reset` value; `sub announcements --limit 1` returns one entry with a
+`reddit.com/r/announcements/comments/` URL. With credentials set, `doctor` prints
+`active_backend: oauth` and `thread …` output shows numeric scores.

Subject: [PATCH 053/276] docs(skills): reddit-reading spells out that no login
 is needed and OAuth is app-only

The default backend needs no Reddit account, login, cookie or API key; the
optional upgrade is a free 'script' app registration using the app-only
client_credentials grant, never a user login. Said in the skill's
Prerequisites (with a comparison table), Procedure, Pitfalls, the runtime
doctor/thread notes, and a delimited .env.example block.

Subject: [PATCH 055/276] fix(toolsets): merge MCP tools when alias collides
 with static toolset
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If an MCP server registers itself under the same name as a built-in
toolset (e.g. an MCP "homeassistant" running alongside the built-in
`homeassistant` toolset), `get_toolset()` returned the static definition
early and the MCP tools were silently shadowed — they got registered
into `mcp-homeassistant` but never surfaced when the agent looked up
`homeassistant`.

Detect the collision via the registry alias (`alias_target` starting
with `mcp-`) and merge the two tool lists. The description is annotated
so the source is visible in `/toolsets info`.

get_toolset() and document the alias/collision behaviour.

Subject: [PATCH 059/276] fix(ssh): isolate prompt backend probes from file
 sync

The prompt-time backend probe built a normal SSHEnvironment just to run a
one-line `uname`. That constructor detects the remote home, creates the
~/.hermes tree, force-uploads every sync file and snapshots a login session;
when the throwaway object was later garbage-collected, __del__ -> cleanup()
ran sync_back() and `ssh -O exit` against the ControlMaster socket the
agent's real environment shares (keyed by user@host:port).

Add an internal probe_only construction path for SSH: an isolated,
same-length ControlMaster socket (keyed by the instance's session id), no
remote dir setup, no FileSyncManager, no session snapshot. The probe now
tears its own connection down explicitly on success, non-zero exit and
exception, without replacing the probe result when cleanup fails. Normal
SSH callers and non-SSH backends are unchanged.

Salvaged from #77933 onto the facade/sibling layout (the probe body moved to
_run_backend_probe, _create_environment to tools/terminal_tool_backends.py).

Subject: [PATCH 060/276] refactor(ssh): drop probe-only bookkeeping the probe
 never reads

- probe_only is consumed inside __init__ only; no instance attribute.
- _sync_manager is assigned only on the probe branch, after the connection is
  up, so a normal SSHEnvironment whose constructor fails still behaves exactly
  as before (its __del__ cleanup does not reach the shared socket teardown).
- _remote_home has no reader on the probe path; not assigned.
- prompt_builder passes probe_only=True unconditionally: which backends honor
  it is the builder table's decision, not a caller-side env_type check.
- Tests trimmed to the probe_only contract: the cleanup-raises case was green
  on main (pre-existing try/except), the socket-name length and double-cleanup
  assertions covered pre-existing behaviour.

 reconnect interrupt claims

Re-scope #98106 onto the activity-based orphan policy from #100504. Keep timer ownership across callbacks and continuations, serialize reconnect paths against interrupt claims, and avoid recursive eager-resume locking. Leave cleanup polling armed when concurrent cold reuse is rejected.

Subject: [PATCH 062/276] refactor(tui-gateway): one _reattach_refusal helper
 for the live-identity/interrupt-settling guard

The 4007/4009 guard the salvaged fix added to prompt.submit, session.activate,
_resume_live_unpersisted and _resume_reuse_live_locked was the same six lines
four times. One helper in session_lifecycle.py (next to _cancel_ws_orphan_reap,
whose contract it mirrors) so the next reattach path cannot drift from the others.
Behaviour unchanged; the 19 race tests cover all four call sites.

Subject: [PATCH 063/276] perf(tui-gateway): session.activate builds its
 payload outside _session_resume_lock

The salvaged fix correctly put the activate guard + transport rebind under the
process-wide resume lock, but it dragged _live_session_payload in with them. The
Desktop passes omit_messages=true (cheap), the Ink TUI does not: every TUI session
switch then read the full persisted history from the profile DB while holding the
lock that serializes every resume, disconnect and reap Timer.

Extract _rebind_live_transport from _live_session_payload; activate does guard +
rebind under the lock (the part that must be atomic with grace expiry) and builds
the payload after releasing it.

 _rebind_live_transport

_resume_live_unpersisted hand-rolled the same transport + viewers + reap-cancel
sequence _rebind_live_transport now owns. Route it through the helper; the
stdio case (no current transport) keeps cancelling the reap as before.

Subject: [PATCH 065/276] refactor(tui-gateway): _rebind_live_transport lives
 with the reattach contract in session_lifecycle

It is lifecycle logic (detached sentinel, reap cancel) and its siblings
_reattach_refusal / _cancel_ws_orphan_reap are already there; server.py is the
facade and gets no new definitions. Also trims the _claim_or_reuse_live comment
to point at where the reap cancel now happens.

waiting for a slot. Reserve a foreground slot, drain foreground first,
and fail background slot-wait quietly.

Fixes #102281.

Subject: [PATCH 070/276] fix(desktop): consume foreground spawn marks and log
 only real slot waits

Follow-ups to the #102496 salvage in the Electron main process:

- pendingForegroundSpawns leaked: promoteInFlightLocalSpawn marked the key
  even when the pool entry already existed (the common click path), and
  nothing consumed it. After that backend was reaped, the next dial for the
  key - normally 10 s roster hydration - spawned as foreground and sat in the
  reserved slot. Mark only when no entry exists yet; spawnPoolBackend consumes
  the mark before any early return (remote route included) so it never
  outlives the dial.
- The "waiting for a free local slot" log fired for a foreground request that
  was granted the reserved slot immediately (condition was queuedCount > 0
  after request()). The request now reports `queued`; log only then.
- One promotePoolEntry() and one logPoolSpawnFailure() replace three copies of
  the promote snippet and two copies of the background/foreground log branch;
  spawnPoolBackend reads entry.spawnPriority instead of a second opts channel;
  isBackgroundSlotWaitTimeout is an instanceof check (same process as the
  class, no duck typing).

Subject: [PATCH 071/276] fix(desktop): tag the route probe of a user open as
 foreground too

Every user open first probes its route (sharedPrimaryRoute /
isAttachedSharedRemote) with getConnection / getConnectionFor, and only then
dials the secondary. With #102496 only the second dial carried
priority: 'foreground', so main started (or joined) the spawn as a background
slot wait on the probe and the click still waited out the probe's 20 s
RECONNECT_ATTEMPT_TIMEOUT_MS before promotion kicked in. Thread the priority
into both probes; the activation doors (ensureGatewayForProfile /
ensureGatewayForAgent) pass 'foreground' explicitly.

Also drop the renderer-side isBackgroundSlotWaitTimeout + the try/catch whose
two branches both rethrew: Electron rebuilds IPC rejections as a plain Error,
so name/silent/priority never reached the renderer and the helper was dead.

Test: gateway-spawn-priority.test.ts asserts every dial of a foreground open
carries the tag and an untagged open never does (red on the #102496 head).

Subject: [PATCH 072/276] fix(desktop): clear an unconsumed foreground spawn
 mark when the dial settles

spawnPoolBackend() is not on every dial path: a primary route (startHermes),
a registry remote scope (connectRegistryBackend), a reused primary SSH
backend, or a guard rejection all settle the claim without requesting a
slot, so a foreground mark set for that dial stayed in pendingForegroundSpawns
and would have upgraded the next background hydration spawn of the same key.
applySpawnPriority() now returns the cleanup; both IPC handlers run it in a
finally around the claim. The mark is also taken right before the slot
request instead of at function entry, so the remote branch never consumes it.

Subject: [PATCH 074/276] fix(desktop): status bar shows for every install,
 including ones that hid it under the old key
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The whole-bar preference lived at `hermes.desktop.statusbarVisible`. For a
stretch (d399c164 → 120e465c) the atom's fallback was `false`, so any
install that launched in that window persisted a hidden bar the user never
chose, and flipping the fallback back to `true` only helped fresh stores.

Move the preference to `hermes.desktop.statusbarVisible.v2` and do not seed
it from v1: every existing install comes back to "on" once on update, and a
hide made afterwards persists under the new key. Fresh installs are on by
default as before.

Subject: [PATCH 075/276] feat(desktop): approval-mode zap shows on the status
 bar by default

Whether dangerous commands run unasked is state worth seeing at a glance,
so the approval pill (yolo lightning) leaves STATUSBAR_HIDDEN_BY_DEFAULT.

Existing stores were seeded with it hidden, so the hidden-set key moves to
`hermes.desktop.statusbarHidden.v2`, seeded from v1 minus `approval-mode`:
other customizations survive, the zap appears once on update, and hiding
it again persists under the new key.

Subject: [PATCH 077/276] fix(sessions): compacted display history keeps
 protected-tail copies in original chronological order

_dedupe_display_generations chose the right representative row per logical
message but sorted the survivors by that representative's id. A protected-tail
copy written into a newer compaction generation has a higher id than messages
emitted after the original, so include_compacted reads came back as C, A, B.
Anchor the sort on the logical message's first-ever row id instead.

Salvaged from #93869 (the tui_gateway half of that PR is superseded by #100504
and #104137); the code moved from hermes_state.py to hermes_state_messages.py
since, so the change is re-applied to its new home with the PR's regression
test verbatim.

Subject: [PATCH 078/276] feat(openrouter): per-model
 provider_routing.models.<id> overrides

`provider_routing.models.<model-id>` now takes the same only/ignore/order/sort/
require_parameters/data_collection keys and overlays the flat provider_routing
values whenever the agent is on that model. Resolution lives in the one
chokepoint every request path already uses (_provider_preferences_for_agent),
so CLI, gateway, TUI/Desktop, cron, /model switches, fallback activation and
delegated children on another model all honour it with no per-surface plumbing.
Matching is spelling-tolerant, sharing _canonical_model_variants with
agent.reasoning_overrides.

The OpenRouter profile's speed-tier pin no longer overwrites an explicit user
`only` on the BASE gpt-6-astra slug: the pin exists to keep default routing off
flex/fast, and a user pin is the stronger intent (only: [openai] stays [openai]
instead of becoming [openai, azure, azure/us]). Tier slugs (-fast/-flex) keep
owning `only`.

Live A/B (config only: {gpt-6-astra: [openai], claude-fable-5.1: [anthropic]}):
main sent {"sort":"price"} for fable and OpenRouter served it from Azure; with
this change it sends {"only":["anthropic"],"sort":"price"} and Anthropic serves it.

Schema proposed in #24495 (samplesabotage) and #100711 (Artemonim); this is a
slim chokepoint implementation of that design.

+### Per-model overrides (`models`)
+
+Pin a different provider set per model. Keys under `models` are model ids; each entry takes the same
+`sort` / `only` / `ignore` / `order` / `require_parameters` / `data_collection` keys and overrides the
+flat value for that model only. Anything you don't set per model falls through to the flat defaults.
+

+  models:

+```
+
+Matching is spelling-tolerant like `agent.reasoning_overrides` (`claude-fable-5.1` / `claude-fable-5-1`,
+with or without the `openrouter/` prefix). The override follows the model the agent is *currently* on, so
+`/model` switches, fallback activation, cron jobs, and delegated subagents on another model each get their
+own pins. Edit `config.yaml` directly for these keys: model ids contain dots, which `hermes config set`
+reads as path separators.

Subject: [PATCH 079/276] fix(delegate): subagents never inherit the 1h
 prompt-cache tier

A delegated child copies the parent's prompt_caching.cache_ttl. The 1h tier
is priced for a person who steps away between turns (2x write vs 1.25x for
5m); a subagent calls every few seconds for minutes and is gone, so it paid
2x on every tool result and never collected the retention. Live measurement
(Sep 5, 40 concurrent Fable 5.1 children via OpenRouter, 1h markers on the
wire): cache writes billed at $20/M against $12.51/M for the same run at
5m, ~60% of a write-dominated bill.

_apply_child_cache_ttl runs right after child construction: 1h -> 5m,
5m stays, disabled stays disabled, parent untouched. Tests: unit (markers
on the wire drop ttl; parent's 1h layout still differs) and the real spawn
path with cache_ttl: 1h in a temp HERMES_HOME.

Subject: [PATCH 080/276] fix(memory): refuse batch that would empty a
 non-empty store (#103419)

apply_batch() committed an empty USER.md/MEMORY.md as a normal
successful write when a consolidation batch removed the last entry.
Refuse all-or-nothing with live entries so background consolidation
keeps at least one entry; a deliberate wipe stays a manual file edit.

path's name. "profile" → "store" in the error since MEMORY.md is not a profile.

Subject: [PATCH 088/276] test(update): pin the refused-receipt shape the
 stop_reason clause exists for

update_contract writes {"outcome": "refused", "stop_reason": <code>} with no
exit_code; that is the one production receipt where the stop_reason clause in
_receipt_looks_unfinished is load-bearing. The previous negative control used
exit_code=1, which the exit_code branch already catches. Docstring reworded:
a KeyboardInterrupt never lands on a success receipt (the boundary finalize is
a no-op once the inner path finalized).

Subject: [PATCH 089/276] refactor(update): name the success invariant in
 _receipt_looks_unfinished; one predicate contract

The tail clause was correct only by ordering (exit_code != 0 there meant
exit_code is None). Name what it encodes: a stop_reason counts only when
nothing vouched for success. Same truth table. The three literal-dict tests on
the predicate collapse into one parametrized contract; the handoff-exit test
binds to COMMAND_BOUNDARY_STOP_REASON instead of re-spelling it.

Subject: [PATCH 090/276] fix(process): drop OOMPolicy from systemd-run --scope
 argv

OOMPolicy is a service-unit property; systemd-run --user --scope
rejects it with 'Unknown assignment: OOMPolicy=kill'. The availability
probe therefore always failed in supervised Linux gateways, making
restart-safe cron worker dispatch (systemd scope) permanently
unavailable and falling back to in-cgroup workers.

MemoryMax + MemoryAccounting remain; OOMPolicy adds nothing for a
transient scope (no service manager to act on the OOM event).

The spawn_local systemd test asserted the property was present; it now
asserts the invariant the fix establishes (no OOMPolicy= on a transient
scope), so a reintroduction fails here instead of on older systemd hosts.

 Portal rejects the provider object

Portal decides routing centrally per model and returns HTTP 400 on any
caller-supplied `provider` object (live-confirmed). Drop the five "OpenRouter or
Nous Portal" claims from the provider-routing page and say plainly that the
setting is ignored on Portal now that the profile no longer forwards it.

Subject: [PATCH 097/276] fix(desktop): stop double-quoting expandRemotePath
 fragments in the SSH spawn path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

expandRemotePath() returns an already-quoted shell fragment
("$HOME"'/path'), but three call sites wrapped its output in shq()
again: the withRemoteUpdateMutex python argv, the reservation/lock/
owner_file assignments in buildSpawnCommand, and the identity values in
buildOwnedStaleTerminationCommand.

The remote shell strips only one quoting layer, so python received a
mutex path with literal quote characters in it (creating a directory
literally named ' in $HOME), and the payload's mkdir "$reservation"
loop spun on a path that can never exist. Every Desktop SSH backend
spawn hung until the connect timeout, retried, and left an orphaned
flock queue behind; stale-owner cleanup always printed REFUSED for the
same reason.

The regression test parses the composed command with a real sh — the
same parse the remote login shell performs — and requires the mutex
path and the payload's reservation paths to come out fully expanded.

Both files are 0 bytes, nothing in the tree references them, and the leading
and trailing `'` are part of the filenames. They are the fingerprint of the
double-quoted mutex path in `withRemoteUpdateMutex()`: the path reaches Python
with its shell quotes still attached, so it is treated as CWD-relative and
`os.makedirs()` materialises the whole absolute path under whatever directory
the process happened to be in. Running
`apps/desktop/electron/remote-lifecycle.test.ts` from `apps/desktop`
reproduces it on the spot.

They were swept in by a `git add .` in 36620578f0, an unrelated menu-label
commit.

This only removes the committed artifact. The generator is a separate concern
already covered by open PRs (#99189, #96187, #96260) and issues (#99133,
#96212, #96188); those repair the quoting but none of them deletes these two
files, so the litter would survive whichever one lands.

Subject: [PATCH 099/276] test(desktop): tighten the real-sh mutex quoting test

Review follow-ups on the #96187 cherry-pick: skip on win32 like the
sibling tests that shell out; reuse the file's `exec` helper; one temp
root so a failing second mkdtemp cannot leak the shim dir; quote the
shim's redirect target; guard the payload-prefix sentinel so a renamed
loop marker can never make the test execute the real spawn payload;
drop the lockMetadata fields the assertions never read. Move the
mutexPath contract into withRemoteUpdateMutex's doc comment instead of
a third inline restatement.

Subject: [PATCH 101/276] fix(delegation): number delegation batches per
 conversation, not per process
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`format_batch_tag` handed out `set N` ordinals from one process-wide table,
so every conversation on a shared backend and every child's nested fan-out
advanced the same counter. A user's second wave of 15 lanes rendered as
`[set 20 · 13/15]`, which reads like 20 batches were spawned.

Scope the ordinal table by the parent conversation (`parent_agent.session_id`)
and thread the parent through the three render sites (batch header,
completion lines, child tree-line prefix via the shared session_ref). The
first fan-out in a conversation is `set 1`, the next `set 2`; sibling
conversations and nested child batches no longer inflate it.

Invariant test proven red on origin/main, green with the fix.

Subject: [PATCH 102/276] fix(tools): read_file dispatch honors the advertised
 2000-line default when the model omits limit

#76996 raised DEFAULT_READ_LIMIT, the read_file_tool signature and the schema
default from 500 to 2000, but the registry dispatch handler `_handle_read_file`
kept its own literal `args.get("limit", 500)`. Since models omit `limit` on most
reads, every dispatched read still stopped at 500 lines with `truncated: true`,
so the default flip never reached production traffic.

All three sites now read the single DEFAULT_READ_LIMIT constant, so the schema,
the Python default and the dispatch fallback cannot drift again.

Live probe (registry.dispatch on a 1500-line file, no limit): before 501 lines /
truncated=true; after 1501 lines / truncated=false.

Subject: [PATCH 103/276] fix(mem0): lazy-import _read_mem0_json to avoid
 ImportError during plugin load

The plugin loader pre-registers empty shells in sys.modules before
executing any submodule. When _setup.py ran 'from . import _read_mem0_json'
at module level, Python found the empty parent shell (init not yet executed),
so the import failed silently. This left _setup.py partially loaded and
post_setup undefined, causing 'cannot import name post_setup' during
hermes memory setup mem0.

Move the import inside the three functions that use it, matching the
late-import pattern __init__.py already uses for post_setup.

Fixes: hermes memory setup mem0 crashing with ImportError

Subject: [PATCH 104/276] test(mem0): setup module keeps post_setup when
 discovery imports the package first
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The plugin loader execs sibling modules before the package __init__, so a
module-level `from . import _read_mem0_json` in _setup.py failed against the
empty parent shell and the whole module silently dropped out — every later
`hermes memory setup mem0` died with "cannot import name 'post_setup'".
The test loads mem0 through the real discovery path from a cold sys.modules
and asserts the cached _setup module exposes post_setup (red on base).

Also maps the contributor email for #103078 credit.

Subject: [PATCH 105/276] fix(cli): refuse to persist a truncated JSON reply as
 profile description

hermes_cli/profile_describer.py's aux-LLM response parser is documented as
"lenient, never raises": when the reply doesn't parse as JSON via
_extract_json_blob, it falls back to treating the WHOLE raw reply as plain
prose and persists it (truncated to 280 chars) as profile.yaml's
description.

That fallback exists for models that ignore the JSON-output instruction and
just answer in prose -- reasonable. But it doesn't distinguish that case
from a reply that DID start out as the requested JSON object and was cut
off mid-object by the aux model or transport. _extract_json_blob requires a
matching closing brace, so a truncated object (no `}` at all, or one cut
off mid-string) returns None just like plain prose does, and the fallback
then persists the raw JSON fragment verbatim: literal leading `{`, `\n`
escapes, a sentence chopped mid-word (#104067).

Fix: when parsing fails, check whether the reply (after the existing
code-fence strip) still looks JSON-shaped (starts with `{`). If so, it's a
malformed/truncated structured reply, not prose -- refuse it and return
ok=False instead of persisting the fragment. Only fall through to the
raw-text-as-prose fallback when the reply never looked like JSON to begin
with, so genuinely prose-only aux replies keep working exactly as before.
Also logs one INFO line on the refusal path, per the issue's note that the
silent fallback made this undiagnosable.

Update (review feedback from @jerrygooch): profile_describer._FENCE_RE was
case-sensitive, so an uppercase ```JSON fence wasn't stripped -- stripping
left "JSON\n{..." which doesn't start with "{", so a truncated response
under that fence variant still fell through to the prose fallback and got
persisted, defeating the fix for that case. Added re.IGNORECASE to
_FENCE_RE, aligning it with kanban_specify._FENCE_RE (which already used
re.IGNORECASE), and added a regression test for the uppercase-fence case.

Added tests/hermes_cli/test_profile_describer.py coverage: a truncated
object cut off mid-sentence (the real-world shape from the issue), one cut
off right after the opening brace, the same truncation under a ```json
fence, the same truncation under an uppercase ```JSON fence, and a
regression guard that a genuine plain-prose reply still hits the existing
lenient fallback unchanged.

Fixes #104067

Subject: [PATCH 106/276] test(profiles): two invariants for the truncated-JSON
 refusal, comment trimmed to the why

Parametrized refusal test (bare/fenced/uppercase-fenced truncated objects) asserts
profile.yaml is byte-identical afterwards; one prose test keeps the lenient
fallback contract. Replaces five near-duplicate tests from #104075.

Subject: [PATCH 107/276] fix(slack): drop markdown_text from native task-card
 appendStream payload

chat.appendStream rejects a request carrying both markdown_text and
chunks with `cannot_provide_both_markdown_text_and_chunks`, so every
native task-card update failed and each turn silently downgraded to the
plain-text fallback message (#87743). The chunks are the native
rendering; the gateway caller keeps its own editable-text fallback rail
for when the native call itself fails, so the markdown_text field was
both rejected and redundant.
Fixes #87743

Subject: [PATCH 108/276] test(evals): wire-contract A/B harness for Slack
 chat.*Stream payloads

Replays the native task-card rail and the text-stream rail through the real
slack_sdk AsyncWebClient against a local aiohttp receiver that enforces the
documented markdown_text/chunks mutual exclusion. Local contract proof, not
Slack live: records outgoing bodies before/after #87743.

Subject: [PATCH 109/276] fix(gateway): stop printing sys.maxsize as an
 iteration ceiling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rebase of the existing fix onto current main: the god-file split that
was in flight when this PR opened has landed, moving both original
call sites out of gateway/run.py into gateway/run_busy.py and
gateway/run_turn.py, which is why this PR showed a merge conflict.
Also folds in a third call site (see below) that a competing PR
(#102845, closed by its author in favor of this one) identified after
this PR first opened.

Three user-facing gateway status lines render "iteration N/M" from
AIAgent.get_activity_summary()'s api_call_count / max_iterations pair:
the long-running heartbeat (run_turn.GatewayTurnMixin.
_run_agent_notify_long_running), the busy-session acknowledgment
(run_busy.GatewayBusySessionMixin._compose_busy_ack_message), and the
gateway-timeout diagnostic message shown to the user when a run is
force-timed-out for inactivity (run_turn.GatewayTurnMixin.
_run_agent_timeout_result). AIAgent.max_iterations defaults to
sys.maxsize (unlimited tool-calling iterations for a top-level session
-- see run_agent.py), so all three printed the literal
9223372036854775807 as the denominator, e.g.:

  ⏳ Working — 3 min — iteration 2/9223372036854775807, receiving stream response

That reads as a bug rather than "unbounded" and is meaningless to a
user.

Add _format_iteration_progress() to gateway/run.py, a small shared
formatting helper: once the configured max_iterations is at or above
sys.maxsize, it renders "iteration N" alone and omits the denominator;
a genuinely finite budget (e.g. a subagent's delegation.
max_iterations: 250) still renders "iteration N/M" as before. All
three call sites now go through it. The gateway-timeout diagnostic
message's own operator-facing logger.error() call keeps the raw
resolved value for diagnostics -- only the two user-facing diag_lines
built from it are reformatted.

Added tests/gateway/test_format_iteration_progress.py (the helper's
own unit tests: unbounded default, above-sentinel values, finite
budgets, and graceful handling of a missing/malformed max_iterations),
tests/gateway/test_gateway_timeout_iteration_progress.py (both
diagnostic-message branches, unbounded and finite, plus the heartbeat
call site exercised end to end through its async polling loop), and a
new regression test in tests/gateway/test_busy_session_ack.py::
TestBusySessionAck::test_status_detail_omits_denominator_for_unbounded_max_iterations
that exercises the busy-ack call site end to end with the real
sys.maxsize default and asserts the sentinel never reaches the
rendered text.

Defect 1 in the original report (a direct_result tool's raw output
occasionally becoming the user-visible reply) is left for a separate
change -- the reporter frames it as an open core-level design question
("a per-turn suppression option... would fix the class for all
plugins"), not a drop-in fix, and it touches reply composition rather
than status-line formatting.

Part of #102806 (defect 2: the iteration-ceiling display; defect 1 is a separate change).

Subject: [PATCH 110/276] refactor(gateway): iteration-progress formatter lives
 in agent/session_activity, tests trimmed to the invariant bar

The salvaged helper was appended to the gateway/run.py facade; new behaviour
belongs in a topical sibling. agent/session_activity.py already owns the
activity-snapshot contract the three render sites read from, so the formatter
moves there as format_iteration_progress and the three call sites import it at
module level instead of late-importing the facade.

Tests trimmed to the salvage bar (<= 2 invariant tests per fix): one
parameterized contract on the helper (unbounded/None hide the ceiling, a real
budget keeps N/M) plus the contributor's end-to-end busy-ack test through the
real render path. The per-site heartbeat/timeout tests exercised the same
helper through mocks and are dropped; evals/gateway_status_render/
iteration_ceiling_ab.py drives all three real render sites with a real AIAgent
for before/after evidence (3 sentinel leaks on main -> 0).

Related: #103109 (same fix, same target module; credited in the PR),
#102845 (third render site, closed by its author in favour of #102817).

Subject: [PATCH 112/276] fix(webhook): only webhook-signature commits a
 delivery to the Standard Webhooks path

GitLab (lib/gitlab/web_hooks.rb, app/services/web_hook_service.rb) sends
webhook-id and webhook-timestamp on EVERY delivery and adds webhook-signature
only when a signing token is configured. Selecting the HMAC path on any
webhook-* header would 401 every legacy X-Gitlab-Token install the moment it
upgrades to GitLab 19, so only the signature header selects the path; id and
timestamp then travel with it and the validator still fails closed when either
is missing. svix-* keeps its existing any-header selection.

Tests trimmed to the invariant bar: one parameterized contract (whsec_ and raw
secrets accept; wrong secret, tampered body and stale timestamp reject) plus the
GitLab legacy-token coexistence contract. evals/webhook_auth/standard_webhooks_ab.py
drives a real aiohttp WebhookAdapter on a dedicated loopback port with real
signed requests for before/after evidence.

Related: #47849 (HwangJohn, cherry-picked here), #92024 (earlier salvage of
#47849), #102080 and #103167 (same alias fix, same target).

Subject: [PATCH 113/276] fix: route deferred update notice through cprint to
 avoid ANSI garbling

The deferred update notice ("N commits behind") was rendered via
console.print which writes ANSI escapes directly to stdout. Under
patch_stdout (active in the interactive CLI), the StdoutProxy strips
ESC bytes, leaving visible [1;33m...[0m artifacts.

Fix: render Rich markup to an ANSI string via a captured Console, then
route through cprint (which uses prompt_toolkit ANSI parser) to
bypass the StdoutProxy mangling.

This is the same class of bug as #2262 (fixed by #2448 for agent._print_fn
and display.py), but the _defer_update_notice callsite in banner.py was
not covered by that fix.

Fixes #83969

Subject: [PATCH 114/276] fix(banner): deferred update notice keeps
 prompt_toolkit routing; drop dead console arg; PTY harness

Follow-up on the cherry-picked fix: _defer_update_notice no longer takes the Rich console it
can never safely use (the notice always lands after patch_stdout owns stdout), the unit test
asserts the contract at prompt_toolkit's boundary (an ANSI fragment reaches
print_formatted_text, with no raw ESC/markup in the visible text) instead of patching our own
cprint, and evals/cli_deferred_notice.py drives the real CLI under a Linux PTY with a FIFO-gated
update cache to A/B the late-notice cases (garbled on base, clean after).

Subject: [PATCH 116/276] fix(anthropic): DeepSeek thinking replay contract for
 third-party proxies

Third-party Anthropic-compatible relays serving a DeepSeek thinking model
(deepseek-r/v4/pro/flash) follow the same replay contract as DeepSeek's
native /anthropic endpoint: strip signed thinking blocks, preserve
unsigned ones. Previously these sessions hit the generic third-party path
and lost ALL thinking blocks, breaking cross-turn reasoning coherence.

Detection is model-name based (vendor prefixes stripped), gated on the
existing _is_third_party check so direct Anthropic traffic is untouched.

Subject: [PATCH 117/276] test(anthropic): trim DeepSeek proxy replay tests to
 two invariants + local wire probe

Fold the adapter-level unsigned-preservation case and the name-detector matrices
into one parametrized invariant (thinking family keeps unsigned only; non-thinking
DeepSeek and unrelated models still take the generic third-party strip) plus the
native-endpoint immutability guard. Add evals/anthropic_proxy_thinking_replay.py,
a real-AIAgent probe against a synthetic local Anthropic-compatible relay used for
the before/after wire check.

Subject: [PATCH 119/276] fix(codex): masked "invalid_prompt: Request blocked."
 replay rejection reaches the replay-strip recovery
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The ChatGPT Codex backend answers a rejected encrypted-reasoning replay with the
same bare 400 {code: invalid_prompt, message: "Request blocked."} it uses for
genuine blocks. classify_api_error bucketed it as format_error, so the one-shot
repair that already exists for invalid_encrypted_content (disable replay, strip
cached codex_reasoning_items, retry once) never ran and the turn aborted.

Classify exactly that envelope from provider openai-codex — SDK 400 body, SSE
``error`` frame, or the ``response.failed`` text — as invalid_encrypted_content
while keeping format_error's abort-and-fallback hints, so the only behavioural
delta is turn_recovery's replay strip, which still requires cached reasoning
items. A block with nothing to strip aborts exactly as before; other providers,
other messages/codes and the #18028 safety refusals are untouched.

evals/codex_masked_replay_review.py drives a real AIAgent (codex_responses)
against a synthetic local Responses server for the before/after check.
Refs #92353, #92357, #94077.

Subject: [PATCH 121/276] fix(gateway): expand @ references before the reply
 pointer so quoted text stays literal

Follow-up to the truncation removal: with the full reply text in the prepared message, a
`@file:`/`@url:` reference inside the *quoted* message reached the context-reference expander
and read a local file on the replier's behalf (the old 500-char slice hid this for long
quotes; short quotes were already exposed on main). Expansion now runs on the new message
text only; the reply pointer is prepended afterwards.

 With this setup, a group message like `@research_bot @ops_bot summarize this` is processed by `research_bot` and `ops_bot` only. Other Hermes bots in the group stay silent, even if the message is a reply to one of their earlier messages or would otherwise match a shared wake word.
 
+Group conversation text and media captions retain all mentions, including the receiving bot's own handle. Each turn also includes the bot's Telegram username and whether the original message explicitly mentioned it. This preserves multi-bot addressing without treating replies, wake words, or open-group messages as explicit mentions. Slash commands still use the normal command-trigger cleanup.
+
 Set `exclusive_bot_mentions: false` only for legacy groups where explicit mentions should not override reply and wake-word triggers.
 
 To operate several profiles, run the gateway command once per profile. For example:

Subject: [PATCH 123/276] fix(telegram): strip our handle only as sole
 addressee; keep the identity line session-stable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two corrections on top of the mention-preservation pick:

- Stripping our own trigger handle from every group message was replaced by never stripping
  it in groups, which broke the pre-existing contract that `@bot 2` answers a pending clarify
  prompt and `@bot ok` approves (the intercepts match the exact stripped text). Strip only when
  no other participant is named; when other bots/users are mentioned the text is kept verbatim
  so `@research_bot , @ops_bot …` no longer arrives as `, @ops_bot …`.
- The addressing block carried a per-message fact ("explicitly mentions you: yes/no") inside
  `channel_prompt`, which is part of the cached-agent signature: a mention turn followed by a
  reply turn rebuilt the AIAgent (prompt-cache miss) every time the shape flipped. Keep only
  the username line, byte-identical for the life of the session.

Tests rewritten to pin both contracts (sole-addressee stripping; identical channel_prompt and
agent signature across a mention turn and a reply turn).

 With this setup, a group message like `@research_bot @ops_bot summarize this` is processed by `research_bot` and `ops_bot` only. Other Hermes bots in the group stay silent, even if the message is a reply to one of their earlier messages or would otherwise match a shared wake word.
 
-Group conversation text and media captions retain all mentions, including the receiving bot's own handle. Each turn also includes the bot's Telegram username and whether the original message explicitly mentioned it. This preserves multi-bot addressing without treating replies, wake words, or open-group messages as explicit mentions. Slash commands still use the normal command-trigger cleanup.
+Group conversation text and media captions keep every mention when the message names other participants too (`@research_bot , @ops_bot are you both listening?` reaches `research_bot` verbatim); when this bot is the only one addressed, its own handle is still stripped so short answers such as `@hermes_bot 2` keep working. Group turns also carry the bot's own Telegram username in the per-channel context so the model can tell which retained mentions are for it. Slash commands still use the normal command-trigger cleanup.
 
 Set `exclusive_bot_mentions: false` only for legacy groups where explicit mentions should not override reply and wake-word triggers.

Subject: [PATCH 125/276] test(fallback): keep the two persisted-config
 invariants; PTY harness for the picker error path

Trim the salvaged suite to the behaviour contracts: a picker exception or Ctrl+C leaves
config.yaml's model exactly as snapshotted (parametrized), and an absent active_provider
stays absent through snapshot+restore. The mock-dispatch tests (asserting calls into our own
helpers) are dropped. evals/cli_fallback_add_picker_error.py drives the real
`hermes fallback add` under a Linux PTY into an ordinary picker OSError and checks the
persisted model: stranded on base, restored after.

+"""Drive the real ``hermes fallback add`` under a Linux PTY into an ordinary picker error.
+
+Run from the checkout with the project Python. No provider requests are sent: the picker
+target is a saved custom provider with ``discover_models: false``. The auth store is made
+unreadable AFTER the provider menu renders (the pre-picker snapshot has already happened), so
+the canonical picker writes the temporary primary route to config.yaml and then fails inside
+``deactivate_provider`` with a plain ``PermissionError`` -- not ``SystemExit``.
+
+The invariant under test: config.yaml ``model`` must equal the pre-picker primary afterwards.

Subject: [PATCH 127/276] docs+test(models): Gemini 3.7/3.8 Flash in the Gemini
 and Vertex guides; curated Google Flash pickers must bill via the official
 snapshot

Follow-up to the salvaged contributor commit: the Gemini and Vertex guide model
tables now list both Flash generations the pickers offer, and an invariant test
ties the OpenRouter/Nous curated google/gemini-*-flash entries to (a) a Google
official-docs pricing row on the direct Gemini and Vertex routes and (b)
membership in the direct gemini/vertex picker lists. Red on main
(gemini-3.7-flash -> unknown), green with the contributor commit.

Subject: [PATCH 128/276] fix(nous): route anthropic/* over chat/completions by
 default (nous.anthropic_wire)

Portal serves anthropic/* on two routes. The native /v1/messages wire, which
Hermes has used since 02d5e230858, re-writes the previous turn's prompt cache
on 14-20% of consecutive calls in concurrent tool loops; the chat/completions
route does not. Measured 2026-09-06, 20 concurrent sessions x 6 tool calls on
Fable 5.1, same account, same hour, same first-party pin:

  Nous /v1/messages          180 pairs, 25 stuck (13.9%); 3 earlier 40-session
                             runs 15.0 / 17.3 / 20.2%; unchanged by the pin
  Nous /v1/chat/completions  320 pairs (2 runs), 0 stuck
  OpenRouter direct, pinned  161 pairs, 0 stuck

"stuck" = cache_read on call k+1 equals cache_read on call k instead of
call k's prompt size: the last write was not visible, the turn (~28K) was
written twice. Every stuck pair had byte-identical system, tools and
per-message shas, so it is not client-side mutation. At $10-20/M for
cache writes that is 15-20% of a fan-out's write bill.

The cause is inside the portal's native route (every element of its
outgoing request reproduces clean from outside; NousResearch/api#227
carries the diagnostics). Until it is fixed, anthropic/* rides
chat/completions. nous.anthropic_wire: native opts back in. Cost of
chat: prior-turn thinking travels as OpenAI-style reasoning fields, and
cache_control scopes are translated by the portal's adapter.

Tests: new test_nous_anthropic_wire_default.py reads the knob through the
real config loader in a temp HERMES_HOME and through
resolve_runtime_provider (both settings); the existing native-wire
contract suite selects native via an autouse fixture so the wire keeps
working for the flip-back. Live: a real AIAgent on this branch,
provider=nous + anthropic/claude-fable-5.1, dispatches to
chat/completions with the session_id intact.

+### Nous Portal: which wire carries Claude
+
+Nous Portal serves its `anthropic/*` models on two routes: OpenAI-compatible `/v1/chat/completions` and the native Anthropic Messages wire `/v1/messages`. `nous.anthropic_wire` picks one:
+
+```yaml
+nous:
+  anthropic_wire: chat     # default. "native" = the Anthropic Messages wire
+```
+
+`chat` is the default for now. The native wire is the better transport (signed thinking blocks pass through unchanged, native `cache_control` scopes), but in concurrent tool loops it currently re-writes the previous turn's prompt cache on 14–20% of consecutive calls, which is 15–20% of a fan-out's cache-write bill; the chat route measured 0 on the same test. Set `native` to opt back in (for example once the portal-side fix has shipped). Only `anthropic/*` models are affected; everything else on Nous already uses chat/completions.
+
 ## When does it take effect?
 
 - **CLI** (`hermes chat`): next `hermes chat` invocation.

Subject: [PATCH 130/276] fix(auxiliary): ResourceExhausted spellings reach the
 payment/quota fallback gate

The compression/aux fallback ladder decides "payment error" via
_is_payment_error(), which only knew the spaced "resource exhausted". NVIDIA NIM
and gRPC-style wrappers serialize the same quota signal as ResourceExhausted /
RESOURCE_EXHAUSTED / resource-exhausted, so a 403/429/status-less body carrying
it re-raised instead of walking the configured fallback_chain, and compression
fell to the lossy emergency path. Add the three separator variants to
_PAYMENT_KEYWORDS (same status gate, no broader "exhausted" matching).

evals/auxiliary_resource_exhausted.py drives the real call_llm/async_call_llm
against two local OpenAI-compatible listeners (nvidia profile primary, named
custom fallback) for the before/after check. #85649

 - **Unchanged** → safe to pull upstream changes, copy the new bundled version in, record the new origin hash.
 - **Changed** → treated as **user-modified** and skipped forever, so your edits never get stomped.
 
+Generated runtime caches inside a skill (`__pycache__/`, `.pytest_cache/`, `.mypy_cache/`, `.ruff_cache/`, and a `.pyc` sitting next to its `.py`) are not part of the hash, so running a skill's helper script never marks it user-modified or hides it from `hermes skills list-modified` / `diff`.
+
 The protection is good, but it has one sharp edge. If you edit a bundled skill and then later want to abandon your changes and go back to the bundled version by just copy-pasting from `~/.hermes/hermes-agent/skills/`, the manifest still holds the *old* origin hash from whenever the last successful sync ran. Your fresh copy-paste contents (current bundled hash) won't match that stale origin hash, so sync keeps flagging it as user-modified.
 
 `hermes skills reset` is the escape hatch:

A background delegate_task call used to be ONE async unit: the runner joined on
every child and a single consolidated message re-entered the conversation when
the SLOWEST finished. Fifteen independent PR reviews therefore waited on the
fifteenth before the parent could act on the first.

Each task now carries an optional `group`. `_units_of` partitions the call's
children into units — one per distinct group, one per ungrouped task — and each
unit is dispatched to the async registry on its own, so its results re-enter the
conversation as soon as THAT unit is done. Tasks that must be compared or merged
share a group and still return together.

Capacity is unchanged: every unit of one call joins the first unit's pool slot
(`slot_key` in `async_delegation._dispatch`), so splitting never consumes more of
`delegation.max_concurrent_children` than the call did. Unit ids suffix the
call's id (`deleg_xxxx-1`, `-2`, …) so live transcripts stay under one dir; the
completion block names the group and notes that sibling units report separately;
`active_task_count` counts a unit's own tasks.

 ## Batch Mode Details
 
-When a top-level agent provides a `tasks` array, Hermes returns one background handle, runs the subagents in parallel, and posts one consolidated result after every child finishes. An orchestrator subagent waits for its batch in the current turn so it can synthesize the results.
+When a top-level agent provides a `tasks` array, Hermes returns one background handle and runs the subagents in parallel. Results come back **per completion unit**, not once at the end:
+
+- A task **without** a `group` is its own unit: its result re-enters the conversation the moment that subagent finishes, so five independent PR reviews land as five messages and the agent acts on each without waiting for the slowest one.
+- Tasks that share a `group` string wait for each other and return as **one** consolidated message (use this when the parent must compare or merge their outputs).
+
+```json
+{"tasks": [
+  {"goal": "Review PR #101 ..."},
+  {"goal": "Review PR #102 ..."},
+  {"goal": "Benchmark approach A ...", "group": "bench"},
+  {"goal": "Benchmark approach B ...", "group": "bench"}
+]}
+```
+
+The dispatch handle lists each unit (`units[].delegation_id`, `group`, `task_indexes`); unit ids are the call's id suffixed `-1`, `-2`, …, and every unit of one call shares a single slot of `delegation.max_concurrent_children`, so grouping never changes capacity accounting. An orchestrator subagent waits for its whole batch in the current turn so it can synthesize the results.
 
 - **Maximum concurrency:** 3 tasks by default (configurable via `delegation.max_concurrent_children` or the `DELEGATION_MAX_CONCURRENT_CHILDREN` env var; floor of 1, no hard ceiling). Batches larger than the limit return a tool error rather than being silently truncated.
 - **Thread pool:** Uses `ThreadPoolExecutor` with the configured concurrency limit as max workers
 - **Progress display:** In CLI mode, a tree-view shows tool calls from each subagent in real-time with per-task completion lines. In gateway mode, progress is batched and relayed to the parent's progress callback
-- **Result ordering:** Results are sorted by task index to match input order regardless of completion order
+- **Result ordering:** Within a unit, results are sorted by task index to match input order regardless of completion order; `TASK i/N` labels index the whole call
 - **Cancellation:** Follow-up messages do not cancel a top-level background batch. `/stop` or closing/resetting the owning session cancels its active children. Synchronous orchestrator children still follow their parent's interrupt state
 
 Synchronous single-task delegation from an orchestrator runs directly without thread pool overhead.

Subject: [PATCH 135/276] fix(desktop): cascade a sash drag through sibling
 panes past their floors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A sash drag used to stop the moment its seam partner hit its min size, so a
row of panes behaved like unrelated boxes: growing the Browser tile could not
take space from Chat once the pane between them was at its floor. The drag
now plans the whole run from the pointerdown sizes — the partner donates
first, then its next visible sibling, and so on — and commits once on
release (fixed zones get px overrides, the flex run gets weights).

A reverse drag after a cascade stays local to the seam. Release only folds a
tool zone that THIS gesture took to its floor, so an unrelated rail already
resting there (a minimized Terminal) no longer cancels the Files/Chat commit.

Salvaged from #103166 (Jerry Gooch), trimmed to the sash-drag change; the
width/height lock feature, zone-body context menu and the restored-tool CSS
floor are held as separate decisions.

Subject: [PATCH 136/276] fix(desktop): restore drag previews before the
 release commit folds a zone

When a sash drag folds a tool zone to its rail, the store commit re-renders
only the wrappers whose style prop changed; the flex sibling the gesture
had pinned to `flex: 0 1 <px>` kept that inline preview and could not grow
into the freed space. Restore every captured style attribute before the
commit, on every release path.

Subject: [PATCH 138/276] fix(desktop-update): acknowledge Windows progress
 completion

A delayed browser could miss the 900ms terminal event and spin forever after the updater exited. Retain terminal delivery until the page acknowledges it, bound unavailable-client teardown and failed requests, and preserve a truthful final display.

Fixes #103747. Builds on OutThisLife and Teknium detached handoff work in #83634 and the #75895 quiet-window design. Continues Axl Ibiza Windows update investigation (#60233, #94107, #100763), including source/review contributions carried by merged #93353 and #85170. Existing #102373, #103140, #95719, #97299 and #103632 retain their separate scopes.

Subject: [PATCH 140/276] fix(desktop-update): drop the dead WinForms pump from
 the ack wait

Publish-UiEvent only enters the delivery-wait loop under $script:UiServer,
and Show-ProgressWindow returns before the WinForms card is built whenever
the browser shim is up, so $script:Ui is always null there. The DoEvents
call could never run; the 50ms sleep loop is the whole wait.

Subject: [PATCH 141/276] fix(tui): drive /heartbeat firing from the
 session-owner process (#102056)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

/heartbeat is parsed by the slash-worker process, which starts its own
heartbeat watchdog thread there — but that process never runs turns, so
the queued prompt is armed-but-dead (countdown froze at ~0s, no turn ever
injected). Mirror the existing /loop driver: poll for due heartbeats in
the per-session notification poller and re-enter the live session through
_run_prompt_submit as a plain user turn, preserving alternation and prompt
caching.

(cherry picked from commit 23ae971075f2d8156642f4c268dd010510a7af41)

Subject: [PATCH 142/276] fix(tui): heartbeat ticks share the /loop idle poll
 and rewind when no turn starts

Folds the /heartbeat driver into the existing /loop poll slot (one cadence, one
try/except table) and closes the consumed-tick gap: a dispatch that raises OR is
refused by _admit_prompt_turn (returns False) releases the session claim and rewinds
the persisted fire via HeartbeatManager.abandon_fire(), so the tick stays due for
the next poll instead of advancing fire_count with no turn. abandon_fire refuses to
overwrite a pause/resume/clear that landed between claim and dispatch (mirrors
LoopManager.abandon_tick). Tests use the real SessionDB under a temp HERMES_HOME and
drive the poller loop itself; docs note the TUI/Desktop surface.

Rollback-on-failure idea credited to jerrygooch (#104011, 51df1ed4d04 / 283fa972169);
the driver placement is Halldrix's (#102118). Reported in #102056 / #103044 (Vksh07).

Subject: [PATCH 148/276] fix(update): credit launchd ai.hermes.gateway in
 fleet reconciliation (#103679)

The restart phase records macOS LaunchAgent labels (ai.hermes.gateway).
match_runtime_outcomes used a substring check for "hermes-gateway", so a
successful Desktop update on the default profile always tripped
"Planned runtimes the restart phase never touched" and exited 1.

Use the exact systemd/launchd/s6 matcher for both plan reconciliation
and abort-recovery so the two cannot drift.

Subject: [PATCH 152/276] fix(gateway): honor server retry_after for
 flood-capped sends instead of plain-text fallback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Flood-capped / rate-limited sends (Telegram FloodWait, Weixin bare RuntimeError)
were not honored as retryable when retry_after was absent, so _send_with_retry
fell through to the truncating plain-text fallback, which re-entered the server
ban and dropped the message tail — silently burning the turn with no delivery.

Three changes to _send_with_retry:
1. Route rate-limit checks through _is_rate_limited_error (single wrapper over
   classify_send_error) so rate limits are treated as transient even when the
   platform omits retry_after.
2. Reclassify rate-limit per retry attempt, not just the initial send, so the
   in-loop break/continue reflects the CURRENT attempt (covers transient->flood
   and rate-limited->formatting transitions).
3. Never take the truncating plain-text fallback for a rate-limited send — return
   the typed failure so the delivery ledger owns redelivery after the cooldown.
   And when retries exhaust on a rate-limited / retry_after-carrying failure,
   return BEFORE sending the delivery-failure notice: the notice send would land
   inside the same flood penalty and re-enter the ban ([0, 189, 378, 378] -> 3
   sends, no 4th). Ordinary exhausted network errors keep the existing notice.

Honors server retry_after (when present) as the backoff delay instead of the
default exponential schedule.

Rebased onto current main (was 5163 commits behind, CONFLICTING) and folded in
reviewer feedback. Regression coverage in tests/gateway/test_send_retry.py:
rate-limit classifier, rate-limited-without-retry_after retries & succeeds,
rate-limited exhaustion returns a typed failure with no fallback and no notice
inside the active flood penalty, and failure-kind transitions between attempts.

Subject: [PATCH 154/276] fix(gateway): cap the inline server retry_after wait;
 return the typed failure past 60s

Review follow-up on the salvaged #100072 flood handling. Honouring retry_after
is right, but sleeping it verbatim in _send_with_retry would pin the send
coroutine for a long penalty (a 97-minute FloodWait once froze inbound on
every platform, #91969 -- the Telegram adapter already fails closed at 5s for
the same reason and hands the wait to this loop). Past 60s the typed failure
goes back to the delivery ledger, which owns redelivery after the cooldown.
The six classifier tests collapse into one parametrized contract.

Subject: [PATCH 155/276] refactor(gateway): drop the unreachable post-loop
 rate-limit guard; trim tests to the contracts

A rate-limited error classifies as network above and the retry loop only breaks
on a non-transient, non-rate-limited error, so the fallback-path guard could
never fire. Tests: the classifier delegator's vocabulary tests were a
change-detector; two rate-limit loop tests were subsumed by the exhaustion
contract (3 sends, no notice, no fallback).

Subject: [PATCH 156/276] fix(verify): refuse compose recipes against a project
 with running containers

Fixes #103567.

`hermes verify`'s compose recipe (`agent/verify/recipes.py::_detect_compose_recipe`)
unconditionally runs `docker compose build` + `docker compose up` against any
directory containing a `docker-compose.yml`, with no check for whether that
directory is already a live deployment. On an image-hash change, `docker
compose up` replaces the running containers -- destroying any state stored
on a container-local path or anonymous volume (not a bind mount).

This caused a real incident: several kanban workers each ran `hermes verify`
as routine self-verification against a workspace that was simultaneously a
live compose deployment; each invocation auto-built and auto-upped the
project; the container carrying a live state DB was replaced (state lost,
recovered from a periodic guard backup after a ~98 minute outage). Nothing
in verify's output indicated it was about to touch live containers.

Implemented the issue's "at minimum" suggested fix: before running any
phase for a `kind == "compose"` recipe, check for running containers via
`docker compose ps --status running` (read-only, never mutates anything).
If any are found, refuse outright with a clear message naming the running
containers, without ever invoking the real `build`/`start` commands as
subprocesses. The refusal surfaces through the exact same PhaseResult/
VerifyResult contract every other phase failure uses (a synthetic failed
"build" phase), so `hermes verify`'s existing JSON/text reporting requires
no special-casing.

The check is best-effort: when `docker compose ps` itself can't run (docker
not installed, or some other environment issue), the function returns None
(not an empty list) and verify proceeds normally rather than blocking on an
unrelated environment gap -- matching how every other recipe kind already
behaves when its own tooling is unavailable. The guard is scoped strictly
to `kind == "compose"`; every other recipe kind (Node, Python, Go, Rust,
Java, Makefile) is completely untouched and never even probes docker.

Verified directly: constructed the exact reported scenario (a compose
Recipe, `docker compose ps` returning running container names via a mocked
subprocess.run) and confirmed run_verify() returns a failed result with a
single synthetic phase, no build/start subprocess ever spawned. Also
verified: no running containers proceeds normally (the real build phase is
attempted); the docker-unavailable case proceeds normally rather than
blocking; and a non-compose recipe never even calls the guard function.

Added 5 regression tests to the existing
tests/verify/test_environment_and_runner.py, following its established
Recipe/run_verify/tmp_path test pattern. Verified as a genuine regression:
reverted just the guard block and confirmed the primary refusal test fails
(the guard's protective behavior is gone) -- a second test that would have
gone on to actually invoke `docker compose build` as a real subprocess
without the guard was interrupted rather than left to run against a
sandbox with no docker daemon, since the first test's failure already
conclusively demonstrates the regression.

24/24 pass in the modified test file; 21/21 pass across two additional
related verify test files (no regression).

Subject: [PATCH 157/276] fix(verify): refuse compose build/up when the
 live-container probe cannot answer

Review follow-up on the salvaged #103577 guard. Fail-open on a hung or failing
`docker compose ps` reopened the #103567 window: containers may be live and
unobservable, and `docker compose build` would fail against the same daemon
anyway, so refusing loses nothing. Only a missing docker binary falls through.
The guard now also runs only when a mutating phase (build, or start without
skip_start) is selected. Tests collapsed to three contracts: refusal spawns
nothing mutating (running / timed out / failed probe), fall-through (none
running / docker absent), guard skipped for non-mutating phase selections.

Subject: [PATCH 158/276] refactor(verify): one honest return type for the
 compose live-state probe (str | None)

The helper returned container names OR a synthetic pseudo-name so the caller
would refuse; on a hung daemon that rendered as "already has running
container(s) (<docker compose ps timed out ...>)". It now returns the refusal
reason or None, and the caller prints the reason as given.

Subject: [PATCH 159/276] fix(email): send IMAP ID only when the server
 advertises the capability
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

_send_imap_id() sent RFC 2971 ID unconditionally after login (a
163/NetEase requirement). Servers without the extension can react badly:
Purelymail answers with an untagged '* BYE Unknown command.' and closes
the connection, which imaplib cannot surface at the call site — the
failure appears one command later as 'IMAP connection failed: command:
SELECT => Unknown command.' and the adapter retries forever.

Gate the ID send on the server's advertised capabilities
(imap.capabilities, populated by imaplib at connect), keeping the
existing exception handler for servers that advertise ID but reject it.
Ports PR #39861 to the current plugin layout, as requested by the
hermes-sweeper review there.

Fixes #39856

Subject: [PATCH 161/276] test(relay): the OpenAI-stream e2e no longer
 deadlocks when Relay's finalizer has not started yet

Relay's producer is pumped by the consumer thread's own event loop (ManagedLlmStream.__next__ -> run_until_complete), so the finalizer can only START inside a consumer next(). The harness blocked the consumer in _count_chunk waiting for the finalizer to start; when the loop had not reached it yet by the final chunk, that wait could never be satisfied and expired at 5 s. Reproduced ~1 run in 6 locally with a thread dump (consumer parked in Event.wait, no other thread anywhere near Relay); it took two unrelated PRs red in CI the same day (#103476, #103486).

The hook now forces the ordering only when the finalizer has already started (that is the race under test), releases it otherwise, reports whether the race was forced, and the two tests repeat the stream until it was, asserting the invariant on every run. 15/15 green; with 74de0fd4fe's agent/ change reverted the tool-call test still fails 3/3, so it keeps guarding what it pins.

Subject: [PATCH 162/276] test(relay): force the finalizer-before-consumer
 ordering deterministically by pumping the stream's own loop

Independent review showed the retry version was a scheduling lottery: under a
forced consumer-first schedule (provider generator held at the terminal chunk
until the consumer took it) both tests failed after 12 attempts with correct
production code. The reviewer also demonstrated the deterministic alternative;
this adopts it. At the chosen chunk the hook releases the finalizer and pumps
the stream's OWN event loop (stream._loop.run_until_complete over a
to_thread wait) until the finalizer has completed, then hands the chunk to the
consumer: a real happens-before on every schedule. A schedule probe's gate on
the provider generator is released first so the pump can reach EOF. The retry
helper and the race-forced plumbing are gone; each test runs once.

Adverse consumer-first schedule (reviewer's probe plugin): 3/3 pass (was 0/3).
Normal schedule: 6/6. Production fix 74de0fd4fe reverted: tool-call test still
fails, so the guard is intact.

Subject: [PATCH 163/276] fix(agent): honor Retry-After on retryable 5xx

Retryable server errors can carry provider cooldowns just like 429 responses. Parse Retry-After from response headers or structured error bodies before falling back to jittered backoff, and cover HTTP 524 behavior with runtime regression tests.

Subject: [PATCH 164/276] fix(agent): parse nested retry_after bodies and emit
 long 5xx cooldowns

Salvage follow-ups on #88236 (krunkosaurus):

- Some providers nest the cooldown as body["error"]["retry_after"] (the
  same unwrap _extract_rate_limit_context already uses); only the top-level
  shape was read, so those errors silently fell back to jittered backoff.
- A 5xx Retry-After can reach the 600s cap; that wait was buffered
  (replayed only on terminal failure), leaving the user silent for
  minutes. Long provider cooldowns now emit immediately, mirroring the
  zai_coding_overload_long path. Jittered waits keep the old buffering.

Test widened with the nested-body parametrize row; proven red when the
unwrap is neutralized.

Subject: [PATCH 165/276] fix(agent): normalize zero-cooldown semantics, dedupe
 test driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

/simplify-code pass on the Retry-After salvage stack:

- compute_error_backoff now decides "no usable cooldown" exactly once:
  a parsed 0.0 (retry-after: 0, or an HTTP-date in the past, which the
  shared parser clamps to 0) is treated as absent instead of falling
  through an accidental falsy check — prevents a hot-loop retry and
  keeps the sentinel semantics uniform (is None / is not None at all
  four sites).
- Comment corrected: the sibling unwrap lives in
  extract_api_error_context, not _extract_rate_limit_context.
- Test driver deduped: one _retryable_error factory + one _drive_once
  shared by the 429 and 524 tests; added the over-cap (3600 → 600) and
  no-cooldown fallback rows requested in the #103722 review.

Mutation checks: nested-unwrap neutralized → nested row red; cap
removed → over-cap row red; restored → all 298 green.

Subject: [PATCH 166/276] test(agent): pin the emit-vs-buffer gate from both
 sides

The simplify reviewers flagged that every cooldown parametrize row was
> 60s, so the emit branch was never asserted against its buffered
complement. _drive_once now records which surface the status went
through, and a 30s row asserts short cooldowns keep the buffered line.
Mutation-checked: flipping the threshold fails the four emit rows.

Subject: [PATCH 167/276] refactor(email): fold #92979 review findings into the
 IMAP ID gate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two shape fixes from the review of #92979, no behavior change:

- Read imap.capabilities directly instead of the getattr(...) or ()
  fallback — a real imaplib.IMAP4 always sets the attribute in
  _connect() (raising if the server sends no CAPABILITY), so the
  default branch only existed for a MagicMock(spec=["xatom"]) that no
  production path produces. Drop the test that pinned it.
- Trim tests to the invariant bar: the four mock tests duplicated what
  test_email_imap_id_protocol.py proves on the wire (real imaplib, real
  socket, command order), and the phase parametrize (startup vs poll)
  exercised the same single _send_imap_id call site twice. Keep the
  three id_mode cases through the poll path.

42 tests pass; mutation check: guard removed -> the absent-ID case
fails with the #39856 SELECT error, restored -> green.

Subject: [PATCH 168/276] fix(compression): defer local preflight after native
 checkpoint

A native Responses compaction checkpoint is opaque ciphertext; the rough
preflight estimator counts it as text (5.17M chars -> ~1.29M tokens against
a 204K trigger) and fires local compression on a request whose real prompt is
~116K. Arm the existing one-response real-usage latch when a replayable
checkpoint is captured (build_assistant_message) or restored into a fresh
agent (_hydrate_from_history), honor it in the post-tool gate and idle
compaction, and require non-empty encrypted_content for a checkpoint.

Squash of the author's source commits from #100642 (0e3c234ea0, 771e1b3365,
bb1505a119) plus the fdf140c81d test refresh, re-based onto current main by
patch application. Source delta is byte-identical to the PR head d6ce3e236d.

Fixes #100611

Subject: [PATCH 171/276] eval(native-compaction): real-AIAgent A/B probe for
 checkpoint preflight false-trigger

Fake local Responses SSE server plays the Codex backend; scenarios cover live
capture (CLI same-object history and gateway reloaded history), SessionDB
close/reopen restore into a fresh agent, and the over-threshold negative where
local compression must still fire after real usage arrives.

+"""A/B probe: does a freshly captured / restored native compaction checkpoint false-trigger
+local compression on the next preflight? (#100611)
+
+Runs the REAL ``AIAgent`` turn loop (``run_conversation``) against a local fake OpenAI
+Responses SSE server that plays the ChatGPT Codex backend role (``provider="openai-codex"``
+→ ``api_mode="codex_responses"``, ``is_codex_backend=True``). No mocks on the agent path
+except a counting wrapper around ``_compress_context`` (a real summarizer call would need
+a second LLM; the question under test is *whether it fires*, not what it writes).
+
+Scenarios (all deterministic, no network beyond 127.0.0.1):
+
+1. ``capture``  — turn 1 returns a ``compaction`` output item carrying N chars of
+   ciphertext plus real usage below threshold; turn 2 in the SAME agent must reach the
+   provider without local compression.
+2. ``restore``  — the turn-1 transcript is written to a real ``SessionDB``, the DB is
+   closed/reopened, a FRESH ``AIAgent`` resumes it; its first turn must reach the provider
+   without local compression (idle pass armed too).
+3. ``over_threshold`` (negative) — same as ``capture`` but the provider's real usage after
+   the checkpoint is ABOVE the local threshold; local compression MUST still fire once real
+   usage arrives (the deferral is one request, not a disable).
+
+Usage (from a checkout root, venv python)::
+
+    python evals/native_compaction/ab_checkpoint_preflight.py --out /tmp/result.json

Subject: [PATCH 172/276] feat(desktop): session import view for foreign
 coding-agent transcripts

Browse the backend host's foreign CLI session logs, preview a bounded read-only
transcript, and continue a copy in Hermes under the selected profile. Reuses the
hermes_cli.foreign_sessions parsers and the portability validator/writer;
imports are transactional and deduplicated on the recorded origin.

Subject: [PATCH 173/276] fix(desktop): skip inaccessible logs during foreign
 session discovery

One unreadable or rotated log must not hide the rest of the list; discovery
tolerates OSError from resolve()/stat() per entry and reuses the stat result.

Subject: [PATCH 174/276] refactor(desktop): import-session entry is a sidebar
 nav row; browser module named as a foreign_sessions sibling

- Sidebar: the entry joins SIDEBAR_NAV (same chrome, active state, data-tour
  handle as the other rows) instead of a one-off Button below the rail;
  i18n moves to sidebar.nav['session-import'].
- Reuse common.retry / common.refresh / common.back instead of duplicating them
  under sessionImport in six locales.
- hermes_cli/foreign_session_browser.py -> foreign_sessions_browser.py so it
  sorts as a sibling of the foreign_sessions module it extends.

Subject: [PATCH 175/276] fix(cli): blank user turn no longer crashes foreign
 session discovery

_first_user_line indexed splitlines()[0] on a whitespace-only user message
(image-only / tool-only turn) and raised IndexError, which aborted the whole
CLI picker and the desktop session.foreign.list RPC. partition("\n") yields
"" for blank text and the loop moves on to the first real user line.
Reported first in #92290.

Subject: [PATCH 176/276] refactor(cli): one foreign-log walker for the CLI
 picker and the desktop browser

hermes_cli.foreign_sessions._walk owns discovery (glob per source, per-entry
OSError tolerance, symlink-escape and regular-file checks, newest first); the
CLI listing and the desktop browser's candidate rows both consume it instead of
carrying two scans of the same directories.

Subject: [PATCH 178/276] feat(nous): anthropic_wire=auto decides a session's
 wire from its first response

Portal will serve anthropic/* from more than one upstream (OpenRouter
passthrough today; GMI/Vertex once it is back online). The native Messages
wire is the better transport but is only safe where the upstream keeps
prompt-cache routing sticky: measured false on the OpenRouter path (14-20% of
consecutive calls re-write the previous turn; #104284 moved the default to
chat), untested on GMI. Hermes cannot see the upstream in the request, only
in the response: OpenRouter stamps `provider` (chat wire) and mints
`gen-<unix>-<rand>` ids; GMI/Vertex returns Anthropic-native `msg_...` ids
and no provider.

`auto` therefore starts every session on chat (correct on both upstreams),
classifies the first response, and switches that session to native only
when the upstream is GMI AND `agent/nous_wire.py::GMI_NATIVE_WIRE_CLEARED`
is True. The switch is scheduled at response time and applied at the start
of the next iteration (turn_iteration_prep), so nothing is rebuilt while a
response is being consumed; it goes through switch_model so the client,
cache policy and _primary_runtime stay consistent. One decision per session,
call 1 only; unknown upstream never switches; a failed switch logs and stays.

GMI_NATIVE_WIRE_CLEARED is False: until the 20x6 concurrency probe
(evals/postmortem/live_ab) is clean on a GMI-served anthropic/* id on the
native wire, `auto` behaves exactly like `chat`. Flipping it is the whole
rollout once GMI is measured. Default stays `chat`.

Tests (17): classifier on real Portal response shapes from both wires and
both upstreams; chat for openrouter/unknown, GMI gated on the flag; one
decision per session, call 1 only, explicit chat/native never auto-switch,
other providers/models untouched, switch failure swallowed and final;
record_response_usage on a real AIAgent invokes the hook once.

Live (auto, real Portal, Fable 5.1): arm A, real classification
(OpenRouter today) - stays on chat through a tool loop and a second turn,
cache 97-99%. Arm B, classifier forced to gmi with the flag on - call 1 on
chat, switch applied before call 2, calls 2-3 on the native wire in the
same session, tool result and both turns correct, cache 97-99%. An earlier
shape that switched inside the response path broke call 1 (SimpleNamespace
has no .content); the scheduled apply is why.

+"""Nous Portal ``anthropic/*`` wire selection when ``nous.anthropic_wire`` is ``auto``.
+
+Portal serves Claude two ways and Hermes cannot tell which from the request: an OpenRouter
+passthrough (today, for every ``anthropic/*`` id) or GMI/Vertex (planned once GMI is back). The
+native Messages wire is the better transport, but on the OpenRouter path it re-writes the previous
+turn's prompt cache on 14-20% of consecutive calls in concurrent tool loops (measured 2026-09-06;
+NousResearch/api#227), so the session must ride chat/completions there. On GMI that is untested,
+and until it is measured ``auto`` never promotes to native.
+
+The upstream IS visible in the first RESPONSE: OpenRouter stamps ``provider`` (chat wire) and
+mints ``gen-<unix>-<rand>`` ids; GMI/Vertex responses carry neither. So ``auto`` starts every
+session on chat (safe on both upstreams), reads the first response, and switches the session to
+native only when the upstream is GMI and native has been cleared for GMI. One decision per
+session, at call 1, before there is a cache to lose; later calls never flip.
+
+``classify_upstream`` is pure and unit-tested; ``maybe_switch_wire_after_first_response`` is
+the single hook, called from the usage recorder.

+`auto` is for when the Portal serves the same model from more than one upstream. A session starts on chat, Hermes reads which upstream answered the first call, and switches that session to native only when the upstream is one where native is known to be clean (the switch happens between calls, so no in-flight response and no warm cache is lost). Today no upstream is cleared, so `auto` behaves exactly like `chat`; it exists so the flip can be made from a measurement rather than a config change.

From: Teknium <127238744+teknium1@users.noreply.github.com>
Date: Sun, 6 Sep 2026 03:49:14 -0700
Subject: [PATCH 184/276] fix(tui): publish session.control.update on every
 control mutation path; drop the Desktop-only heartbeat driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- /goal and /loop are command.dispatch built-ins (never reach the slash worker), so the
  worker-branch publish never fired for the most common typed commands and the structured
  card stayed stale until the next turn. The publish helper now lives beside _snapshot_control
  in methods_session_control.py and is called from both slash paths plus the end of the turn
  tail — after the goal judge / loop tick evaluation, which mutate state AFTER message.complete.
- session.control skips the duplicate emit for dispatcher-backed actions (still exactly one
  update per mutation).
- Removed tui_gateway/desktop_heartbeat_driver.py, the entry/ws hooks and the hermes_cli lock
  rework: #104224 drives /heartbeat from the existing per-session poller for every TUI client.
- test_session_control.py: dropped presentation-shaped cases, added the publication invariants
  (both slash paths, unknown dispatch publishes nothing, real _run_prompt_submit turn publishes
  post-judge). 3/3 new tests fail on the contributor backend.

Subject: [PATCH 185/276] fix(desktop): queue goal-resume continuation when
 busy; wipe session controls on gateway switch

- session-control-goal.tsx: a 'send' dispatch against a busy session now
  parks the kickoff on the composer queue (the backend already resumed the
  goal) instead of reporting continuationFailed. Shared helper
  queueKickoffIfSessionBusy() extracted from slash.ts so both paths agree.
- gateway-switch.ts: wipeSessionListsForGatewaySwitch clears
  $sessionControlBySession (runtime-id keyed; new backend re-mints ids).
  Dead resetSessionControlAfterGatewayRebind removed; clearSessionControl
  now called from the session delete path beside clearQueuedPrompts.
- session-control.tsx: read/hydration failures use controlUnavailable copy,
  not actionFailed.
- i18n: heartbeatDueWaitingForIdle added to ja/ru/zh-hant; new
  continuationQueued/continuationBusy/controlUnavailable in all locales.

Subject: [PATCH 186/276] test(desktop): trim session-control suites to
 behaviour contracts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

session-control.test.tsx 1277→381 lines (32→8 cases): legacy-vs-structured
precedence, action dispatch, send continuation (idle + busy-queue), failure
banner, heartbeat countdown. store/session-control.test.ts 648→472 lines
(26→16): ordering/stale-token invariants, method-not-found downgrade, and a
gateway-switch wipe test replacing the removed rebind seam tests; the
setTimeout-spy 'no timer' test dropped.

Subject: [PATCH 188/276] fix(delegation): a crash mid-unit keeps the children
 that already finished
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since #104299 a background delegate_task call is split into completion units
(one per `group`, one per ungrouped task). A multi-child unit still joined on
all its children before anything was written durably, so an owner crash
between the first and last child lost the finished work and replayed the whole
unit as "outcome unknown" — the restart-granularity gap that #104233 (Xipong's
#76228/#76229 direction) solved with a second row per child.

Each finished child of a detached unit is now recorded on the unit's OWN row
(`record_unit_child` → result_json {results, partial}) as its future lands;
the real result overwrites it at finalize. `recover_abandoned_delegations`
replays recorded children with their real summaries and marks only the
unfinished ones unknown, naming the count. No new rows, no new consumer shape.
`task_indexes` is persisted so recovery knows a split unit's members.

Subject: [PATCH 189/276] perf(prefix-cache): pin session-start workspace
 snapshot across compaction rebuilds

- pin session-start workspace snapshot (_frozen_workspace_snapshot) on first build so dynamic git probes don't churn Tier 2 during compaction rebuilds in active coding sessions
- replay pinned snapshot across rebuilds when cwd matches; re-probe only on cwd switch
- honor coding_context invariant that workspace is a session-start snapshot, preventing prefix-cache divergence at offset ~4,662
- add invariant tests covering workspace snapshot pinning across git mutations and cwd transitions
- addresses upstream prompt divergence identified in #103326

Subject: [PATCH 190/276] fix(prefix-cache): drop the workspace pin at session
 boundaries; bind session cwd for /context
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The pin from the previous commit lives in _SESSION_STATE but nothing cleared it, so a CLI
/new, /resume or /branch (same AIAgent, reset_session_state + _invalidate_system_prompt)
replayed the previous session's git snapshot into the new session's prompt. Clear it in
reset_session_state next to the other session anchors; one invariant test (red without it).

The TUI/Desktop session.context_breakdown RPC ran the prompt builder on the RPC thread
with no session cwd bound, so it re-probed against the backend's cwd and overwrote the
session's pin — one /context between compactions restored the divergence this fix removes.
Bind the session context around the build like the live rebuild in server.py does.

Also: trim _coding_parts' docstring to the WHY, drop the isinstance/len guard on a value only
this function writes, and remove the tests' assertions on the private pin shape.

-    context tier — ahead of the entire volatile band.  Since #98426 the builder runs
-    again at every compaction boundary, so re-probing here re-emits different bytes on
-    any session whose repo moved (a commit, one edited or untracked file), pushing the
-    prefix-cache divergence point in front of skills, memory and the timestamp line and
-    making #98426's byte-equality keep-prompt fast path unreachable in a coding session.
-    It also contradicts the block's own "snapshot at session start" wording and the
-    freeze ``coding_context`` documents.  So the first build pins the bytes on the agent,
-    keyed by the resolved cwd (one gateway serves many cwds, and the per-turn terminal
-    scope can move it), and later rebuilds replay them instead of shelling out again.
-    A resumed process has no pin and legitimately re-snapshots at its own session start.

Subject: [PATCH 191/276] evals(postmortem): cache concurrency probe, the
 instrument behind #104284/#104421 and api#227

N concurrent real AIAgent sessions on a growing tool loop; per-call cache_read /
cache_creation / response id / upstream / prefix shas; consecutive pairs classified
ideal / stuck / collapse. argparse (--provider nous|openrouter|anthropic, --wire,
--pin, --settle, --ttl, --model); wire defaults to what Hermes would pick. Summary
JSON carries bad pairs with both response ids. Smoke-run against Nous from the repo
path (picked chat via nous_api_mode; 6/6 ideal).

+
+The instrument behind #104284 / #104421 and NousResearch/api#227. N concurrent real `AIAgent`
+sessions run the same growing tool loop against a route; every call's cache_read / cache_creation,
+response id, upstream provider and prefix shas are logged, and consecutive pairs are classified
+`ideal` / `stuck` (previous write not visible: routing) / `collapse` (whole context re-written).
+
+```bash
+# ~$50 per 20x6 arm on Fable 5.1 at the 5m tier
+python -m evals.postmortem.live_ab.cache_concurrency_probe --repo . --provider nous --workers 20 --calls 6 --out /tmp/p.jsonl
+python -m evals.postmortem.live_ab.cache_concurrency_probe --repo . --provider nous --wire native --workers 20 --calls 6 --out /tmp/p.jsonl
+python -m evals.postmortem.live_ab.cache_concurrency_probe --repo . --provider openrouter --pin anthropic --workers 20 --calls 6 --out /tmp/p.jsonl
+```
+
+Reference results (2026-09-05/06): Nous native wire 13.9% stuck (14–20% over 4 runs, unchanged by the
+portal's provider pin or a 2 s settle); Nous chat wire 0/320; OpenRouter pinned 0/161; OpenRouter
+unpinned 9.8% collapse. Use this to clear a new upstream before flipping
+`agent/nous_wire.py::GMI_NATIVE_WIRE_CLEARED`. `--ttl 1h` reproduces the 2× write price
+(#104168). The `.summary.json` carries the bad pairs with both response ids for the provider's logs.

+"""Live prompt-cache concurrency probe: does a route keep cache routing sticky under a fan-out?
+
+Runs N independent Hermes ``AIAgent`` sessions concurrently, each the same ~8-step tool loop whose
+context grows 6K -> ~240K, and records for EVERY API call: prompt / cache_read / cache_creation /
+output tokens, the response id, the upstream provider when the route reports one, and a sha of the
+system prompt, tools and every message, so client-side prefix mutation can be ruled in or out.
+
+A consecutive pair (call k, k+1) in one session is classified:
+  ideal     cache_read(k+1) == prompt(k)            the previous call's write was read back
+  stuck     cache_read(k+1) == cache_read(k)        the previous write was NOT visible: routing
+  collapse  cache_read(k+1) <  50% of cache_read(k) the whole conversation was re-written
+  (pairs whose system sha changed are compaction/aux calls and are excluded)
+
+Results that motivated hermes-agent #104284 / #104421 and NousResearch/api#227 (2026-09-05/06,
+Fable 5.1, 20 sessions x 6 calls unless noted):
+  nous, native /v1/messages         13.9% stuck (4 runs 14-20%)     -> chat is the Nous default
+  nous, /v1/chat/completions         0 / 320 pairs
+  openrouter direct, pinned anthropic 0 / 161 pairs
+  openrouter direct, unpinned (40x8)  9.8% collapse
+  2 s settle before every call        no change (not a race)
+
+Usage:
+  python -m evals.postmortem.live_ab.cache_concurrency_probe --repo . --provider nous \
+      --workers 20 --calls 6 --out /tmp/probe.jsonl [--wire chat|native] [--model ID] \
+      [--pin anthropic] [--settle 2] [--ttl 5m]
+  providers: nous (Portal creds from HERMES_HOME), openrouter (OPENROUTER_API_KEY or --api-key),
+             anthropic (ANTHROPIC_API_KEY or --api-key)
+Cost: ~$50 per 20x6 arm on Fable 5.1 at the 5m tier. Every run starts from the real Hermes request
+path; the only patch is a read-only wrapper on the SDK stream that records usage and headers.

Subject: [PATCH 192/276] fix(state): coordinate SessionDB teardown with active
 writers

The #102827 corruption is pure zero holes -- frames lost across a WAL
generation. SessionDB.close() produces exactly that when it runs against a
file another live handle is still writing: PRAGMA wal_checkpoint(PASSIVE),
then the connection close that lets SQLite unlink -wal/-shm. The dangerous
event is a physical close overlapping any other live physical lifetime for
the same path, so both sides of it are closed here.

Late write vs. close: a cron watchdog timeout only stops waiting, and
ThreadPoolExecutor.shutdown(wait=False) cannot interrupt a worker already
inside run_conversation. The agent and its registry reference are now held
until that worker's Future completes, so its last frames land before any
checkpoint.

Close vs. open: the per-path barrier now COUNTS admitted teardowns. A path
can own several closes at once -- the current generation's final release and
a retired generation's drain are admitted independently under the registry
lock, and the per-path mutex only serializes teardowns that already entered
it. With one bare event per path, a releasing thread descheduled between
generation removal and the mutex let the next teardown to settle remove and
signal the shared event: close_all() returned over a pending close and
acquire() published a replacement writer on top of a handle still inside
checkpoint/unlink. _TeardownBarrier tracks event + pending count,
_admit_teardown_locked registers each close in the same lock section that
removes the generation, and only the last settled teardown lifts the
barrier. Physical I/O stays outside the registry lock and unrelated paths
still progress independently.

The auto-archive sweep called release_or_close in its finally while the
import was local to a different function, so every eligible sweep raised
NameError, the outer except Exception swallowed it at debug level, and the
borrowed registry reference was never returned -- a holder leak that pins a
retired generation open. The helper is now bound in the calling scope.

Remaining in-process writable SessionDB() call sites (trace upload, the
API-server profile cache, the web-server writable paths, startup schema
reconcile) go through the canonical registry acquire/release_or_close, and
gateway maintenance borrows pinned handles instead of iterating an unpinned
snapshot.

Regressions: overlapping final releases of the current and retired
generations in both orderings with the first paused before the lifecycle
mutex, teardown-error settlement, an unrelated-path control, and refcount
assertions for the auto-archive sweep on success, on failure, across
repeated sweeps and with auto-archive disabled.

Fixes #102827

Subject: [PATCH 193/276] refactor(cron): detached-worker teardown as a sibling
 module, no guards around a real Future

The deferral helpers from the previous commit were appended to the cron/scheduler.py facade and
carried ~70 lines of fallbacks (getattr/callable checks, result() waits, a teardown_registered
flag) for hypothetical Future doubles; the only producer is _cron_pool.submit, always a real
concurrent.futures.Future whose done()/add_done_callback() cannot raise. Also drops the
_finalize_cron_session_db passthrough. Behaviour unchanged; the test now asserts the
finalize+teardown contract on the real Future instead of a patched wrapper.

Subject: [PATCH 194/276] refactor(state): fold the speculative-open retry into
 acquire's loop; keep real inode-swap tests

- acquire(): the discard-and-recurse path becomes one more iteration of the existing wait loop;
  the two inline 'with lifecycle_lock: _teardown(db)' copies reuse _teardown_generation, and the
  type-narrowing asserts go away with the recursion. release() reads generation.path directly.
- Restore the real os.replace inode swaps in test_state_db_file_identity.py and the registry tests:
  those files carry no windows_only marker so they never run on Windows, and the monkeypatched
  predicate stopped exercising the stat->identity->halt path anywhere.
- Drop the auto-archive change and its 4 tests: on main the sweep gets a bare SessionDB and
  db.close() already releases a registry-shared handle, so the described NameError leak only
  existed on this branch's earlier head. trace_upload: acquire(None) already defaults.
- Trim the barrier tests to the invariant pair (retired drain must not lift a pending current
  teardown; replacement not published before the last close settles) plus the raising-close
  settlement; comments say the WHY once.

Subject: [PATCH 197/276] refactor(bot-mode): re-authorize message_agent on
 staged snapshots without copying the agent

The salvaged fix ran the injector against a copy.copy(agent) whose
tools/valid_tool_names pointed at the staged pair, wrapped in a blanket
try/except. A shallow copy of a live AIAgent (locks, DB handle, in-flight
attribute writes from the late-binding thread) is a workaround for the gate
mutating in place, and the except turned any failure into a silently
published snapshot WITHOUT message_agent.

Extract the gate as tools.bot_mode_dm.message_agent_authorized(agent) (the
same predicate ensure_message_agent_tool already used), and have the
snapshot builder append message_agent_tool_schema() to the staged list
directly when it passes. No copy, no swallow; same tests, same live
behaviour (compaction / between-turns / resume keep the tool; ordinary
sessions scrubbed).

Subject: [PATCH 198/276] fix(browser): make the real-profile attach daemon
 reapable (#100855, salvage #103284)

The `hermes-real-profile` agent-browser daemon (the attach lane for consented
real-profile browsing) ran with plain `_build_browser_env()`: no
`AGENT_BROWSER_SOCKET_DIR`, so it lived in agent-browser's default dir and no
reap path could see it. A wedged daemon + headless Chrome survived 47h across
two gateway restarts (#100855), and on macOS the genuine Chrome binary it held
made "Chrome won't open" for the user.

Give the attach lane the same contract every other lane already has:
`_prepare_session_socket_dir()` (per-session socket dir + `owner_pid` claim)
and `_agent_browser_command_env()`, and add the named dir to the orphan
reaper's scan. The existing `_reap_socket_dir` then applies its owner-liveness
and start-time-fingerprint rules unchanged; the daemon is listed as tracked so
the untracked-idle escape hatch never fires under a live user (per-task `rp_*`
sessions drive it over `--cdp`, so its own dir shows no activity). The daemon-side idle
timeout is NOT inherited: Chrome is launched by Hermes, not the daemon, so a
self-exiting daemon would leave Chrome holding the copy dir while the next
attach re-runs the snapshot overlay over it.

When a reaped daemon's Chrome (Hermes-launched, own process group) still
holds the copy dir, `_real_profile_cdp` re-attaches to it instead of running
the snapshot overlay over a live profile. DevToolsActivePort outlives a
crashed Chrome and its port can be recycled, so the file's browser id must
match `/json/version` before it is trusted; an attach failure on a live
Chrome fails closed rather than overlaying.

Tests: attach/get/close commands carry the reaper-visible socket dir and
owner_pid and no idle timeout; a dead-owner real-profile daemon is reaped by
`_reap_orphaned_browser_sessions`; a surviving Chrome is re-attached, never
overlaid (all red on main).

Subject: [PATCH 200/276] fix(tools): keep truncated search_files output pure
 JSON
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When results were truncated, search_files appended the pagination hint
as plain text after the serialized payload ("{...}\n\n[Hint: ...]"),
so the tool result was no longer parseable JSON — downstream tool-message
handling on providers strict about tool-content formatting could reject
or mishandle it, contributing to 400 upstream errors in sessions with
truncated search output (#90322).

Move the hint into the payload as a structured _hint field, matching the
existing _omitted/_warning side-channel convention in the same function.
The model-facing guidance (explicit next offset) is unchanged.

Fixes #90322

Subject: [PATCH 201/276] test: update cross-tree search hint assertion to the
 structured _hint field
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to the pure-JSON search_files fix: the credential-filter test
in tests/agent/ also asserted the old appended '[Hint: ...]' text — the
local run covered tests/tools/ only, so CI slice 7 caught it. The _hint
field is present and correct in the CI failure output itself; only the
assertion syntax was stale.

Subject: [PATCH 202/276] test: trim #90322 regression to one invariant, drop
 the hint-splitting workaround
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The credentials test no longer has to strip trailing text before json.loads;
the new file keeps the single behaviour contract (truncated output round-trips
through json.loads and carries the next offset) — the existing TestSearchHints
cases already cover offset arithmetic.

Subject: [PATCH 204/276] perf(file-ops): run rg natively for search_files on
 local POSIX hosts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

read_file already bypasses the backend shell on a local POSIX environment
(_read_file_native); search_files still paid two bash spawns per call — the
`test -e` existence probe and `set -o pipefail; rg ... | head -n N` — plus one
per zero-match probe. Measured on macOS against the repo's tools/ tree:
content search 85 ms → 15 ms, no-match search (three probes) 179 ms → 44 ms,
file-name search 73 ms → 12 ms; raw `rg` argv is ~15 ms, so the remainder was
transport.

Same gate and kill switch as reads (_native_read_enabled: LocalEnvironment,
not win32, HERMES_NATIVE_FILE_READ=0 disables). The argv builders and
_parse_search_output are unchanged and shared: _run_rg_native shlex-splits
the already-quoted words, streams stdout and stops after fetch_limit lines
like `head` would, and reports exit 0/1/2 (124 with partial output on
timeout) so the parser sees the shell contract. grep/find fallbacks, remote
backends, Windows and the multi-root cd form keep the shell path.

Two shell-observer tests in test_search_zero_match_and_multipath pin the
shell lane explicitly; they assert on command text, not behaviour.

Subject: [PATCH 205/276] fix(file-ops): native rg runner honours deadline and
 /stop while rg is silent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The first version checked the deadline only after a line arrived, so an rg
that produced nothing for 60 s (huge tree, no hits yet) pinned the caller
past the timeout and ignored the interrupt flag that the shell path honours
via _wait_for_process. Drain on a daemon thread; the waiter owns deadline

survives the return. Probe: silent 10 s process, timeout=2 → 2.0 s / 124;
interrupt at 0.5 s → 0.5 s / 130; zero stray processes afterwards.

Subject: [PATCH 206/276] refactor(file-ops): drop the _native_rg_enabled
 alias, build the files-lane rg command once

_native_rg_enabled was a pass-through to _native_read_enabled (a wrapper with
no behaviour); call the gate directly and note in its docstring that it
covers search too. The rg --files invocation was assembled twice (argv list
for the native lane, string for the shell lane) with room to drift; build the
command string once and hand it to either transport.

Subject: [PATCH 207/276] refactor(file-ops): one _run_rg_bounded owns the
 native-vs-shell transport choice
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three call sites each repeated `if native: _run_rg_native(...) else: _exec(... | head -n N)`.
The choice now lives in _run_rg_bounded; callers pass the words, the bound, and the
one thing the native lane cannot express (a cd prefix → native_ok=False). The grep/find
pipeline keeps its explicit shell form because of the column cap.

Test file: one module-scoped LocalEnvironment instead of thirteen (~0.8 s each).

Subject: [PATCH 208/276] fix(file-ops): reuse _kill_process_group_posix in the
 native rg runner
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A bare os.killpg/signal.SIGKILL trips the Windows-footgun lane (the module is
imported on Windows even though the native lane never runs there). The local
environment already has the POSIX group killer with the TERM→KILL escalation
and setsid-escapee sweep; use it.

Subject: [PATCH 212/276] refactor(gateway): verdict helpers live in
 run_shutdown; keep the early failure return; dedupe test setup

- _exit_with_failure_verdict / _resolve_gateway_exit_verdict move out of the
  run.py facade into run_shutdown.py, which already owns _restart_via_service
  and GATEWAY_SERVICE_RESTART_EXIT_CODE (no alias import needed).
- The running-shutdown tail keeps its early `return False` on a failure verdict,
  as on main, so a failure exit does not first drain cron/MCP; the helper still
  re-checks it for the startup-abort path.
- The three start_gateway tests share one _patch_aborted_startup helper.

Subject: [PATCH 213/276] fix(cron): skip stale-error re-arm while another
 process holds a live fire_claim

Multi-process schedulers sharing one jobs store (gateway + Desktop serve tabs)
re-armed a job every tick while a long run in another process was still
heartbeating its fire_claim, producing claim-fight churn and killing the live
run (brain, 2026-09-02). Treat a fresh fire_claim as 'running elsewhere'.

Subject: [PATCH 215/276] refactor(cron): one FIRE_CLAIM_TTL_SECONDS for
 claiming, one-shot re-arm, and stale-error recovery

The TTL was three copies of the literal 300 (claim_job_for_fire default,
rearm_oneshot, and the new stale-error guard). Hoisted so the three lanes
cannot drift; incident narrative in the guard comment cut to the WHY.

Subject: [PATCH 219/276] refactor(agent): trim the watchdog phase split to
 what the tests pin

- Explicit-vs-implicit idle timeout detection uses env_float with a sentinel
  instead of a hand-rolled parse (unset and unparseable both mean implicit).
- _on_event writes the agent-level timestamps only when there is no
  request-local watchdog state; with state present they were dual bookkeeping
  nobody read (the snapshot prefers the state).
- _abort_request keeps main's close-then-retire order: the reorder had no
  test teeth and is a separate concern from #90449.

 codex watchdog timestamps

With a request-local watchdog state on every codex request, agent._codex_stream_last_event_ts / _last_progress_ts had no remaining reader; the state-None snapshot only runs for non-codex requests where no watchdog consults it.

Subject: [PATCH 224/276] refactor(auth): positive store-identity check for the
 clone strip; drop the save kwarg
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The alias check re-implemented most of _is_same_auth_store (#101356) inline, but
that helper answers False on a samefile() OSError — on the strip path that would
fail OPEN. Resolve identity positively (same resolved path, or samefile says so)
and treat any error as "refuse"; three lines instead of the inline stat dance.
The `preserve_symlinks=False` save path (raw os.replace) bypassed atomic_replace's
EXDEV/Windows fallback to defend against a path swap no concurrent writer performs
on a directory this process just created — removed with its mock-injected test.
Tests kept: shared-store invariant [symlink|hardlink] and two fail-closed variants.

Subject: [PATCH 226/276] fix(desktop): assistant rows whose text persisted to
 sidecars no longer vanish on rehydrate (#68321)

Field-level reproduction (2026-09-02, v0.21.0, in the issue thread): an
assistant row with content length 0 whose user-visible response exists
only in reasoning / reasoning_content / codex_message_items renders
live, then disappears from the transcript after a session/profile
switch-back. DB intact - the row is still there on every re-read; only
the rehydrated render loses it. Six independent confirmations across
macOS and Windows since 2026-07-22; all prior fixes (#68329 envelope
normalization, closed implemented_on_main; #77644 mid-turn reconcile;
#101470 compaction-display projections) addressed adjacent producers,
not this one.

Two producers in toChatMessages hydration, both pinned by the new
chat-messages.reasoning-survival.test.ts (fails 9/9 on current main):

1. codex_message_items never read. Responses-API turns can persist with
   `content` empty while the reply the user saw lives only in the
   message-items sidecar ({type:'message', role:'assistant', phase,
   content:[{type:'output_text', text}]}). The live stream painted that
   text; hydration ignored the sidecar, so the rehydrated bubble came
   back blank - and the blank chatMessageText at the same role-ordinal
   then made reconcileResumeMessages drop the cached row's parts
   (sameText/extension/isLiveTailRow all fail), erasing the reply on
   every switch-back. Fix: codexMessageItemText() extracts
   non-commentary assistant output_text as the bubble's text when
   content and reasoning produced no parts. Persisted content still
   wins when present; commentary narration is never promoted.

2. the zero-parts drop. An assistant row hydrating to no parts at all
   returned early and vanished from the transcript entirely - the
   "all assistant messages gone; user messages remain" shape. Fix: a
   wholly empty assistant row (display_kind != 'hidden') paints a
   _(assistant response not persisted)_ placeholder instead of
   disappearing. Hidden scaffolding rows keep dropping as designed
   (pinned by a test).

Also adds codex_message_items to the SessionMessage type (the gateway
has shipped it since the branch-copy lane; the type never declared it).

Verification (native Windows, node 24.17):
- new file: 9 passed (fails 9/9 without the hydration changes)
- src/lib full dir: 1243 passed
- reconcile suites (utils + resume-structural-parts): 115 passed
- streaming/timeline reasoning-part suites: 25 passed
- tsc --build tsconfig.json: clean

Fixes #68321

Subject: [PATCH 229/276] refactor(desktop): keep the codex_message_items
 hydration fallback; drop the placeholder half

- The placeholder ("assistant response not persisted") is removed: it turned a
  wholly-empty persisted row into TEXT, which in reconcileResumeMessages could
  replace a text-only live stream row at the same ordinal until the turn
  settled. The sidecar fallback alone covers the #68321 field repro.
- Phase filter matches the backend (codex_responses_adapter _OutputScan._message):
  commentary AND analysis are reasoning-channel narration, not the reply.
- Tests trimmed to the two contracts that are red on main; six that passed on
  main (pre-existing reasoning-part behaviour) are gone. File renamed for what
  it now covers.

Subject: [PATCH 235/276] fix(desktop): keep the ssh session token in the v2
 connection registry (#103795)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`persistSshConnectionToken()` writes the per-serve session token adopted for
an SSH connection onto its v2 registry entry, but the registry never read it
back: `normalizeRegistry()` rebuilt an `kind === 'ssh'` entry from
`normalizeSshConfig()` alone, which describes only the DIAL (host, user, port,
keyPath, remoteHermesPath, remoteProfile). The sibling remote/cloud branch
preserves `entry.token`; the ssh branch did not.

The token therefore survived only in the mtime-keyed in-process cache. On the
next cold read — an app restart, or any process that re-parses
connections.json — it was silently dropped, so `resolveRemoteBackend()`
decrypted an empty value and dialed with `reuseToken = ''`. That fails the
`Boolean(reuseToken)` clause of remote-lifecycle's `reusable` gate, so a
HEALTHY owned backend was classified not-reusable, reaped by `cleanupStale()`
and respawned on a new port behind a new tunnel — while the renderer kept
dialing its cached `wsUrl?token=` at the old credential and got 403 forever.

`normalizeConnectionInput()` had the same omission: `saveRegistryConnection()`
resolves the surviving envelope via `resolvePersistedRemoteToken()` and passes
it in, but the ssh branch dropped it, so a plain label rename wiped the live
backend's reuse credential and re-armed the same loop.

Both branches now carry the token exactly the way the remote branch does.
There is no auth-mode choice on an ssh entry that could invalidate the
envelope, so no drop condition is needed.

Fixes #103795

Subject: [PATCH 238/276] fix(desktop): a cross-profile or stale project filter
 no longer empties the sidebar (#96246)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The sidebar's persisted project filter is a membership whitelist over tree node
ids. Ids that the active profile's tree does not resolve (picked in another
profile, or left over after a project was deleted / an update rebuilt the tree)
used to filter every row out — headers rendered, zero sessions, until Local
Storage was cleared. Narrow the persisted filter to ids the live tree resolves;
dead ids are inert, never fatal. Memo-only, never written back.

Salvage of #96269 (three commits: fix + two lint passes, folded).

Subject: [PATCH 240/276] refactor(desktop): one live-filter resolver; keep the
 Home row rule from #102465

#96269 and #102465 fixed the same blank-sidebar symptom with the same
"narrow the persisted filter to ids the live tree names" mechanism.
resolveLiveProjectFilter (the earlier PR) is the single resolver; the
duplicate sanitizeProjectFilter is removed. What #102465 adds beyond it stays:
detached rows file under NO_PROJECT_ID, so filtering to Home keeps Home's rows.

Subject: [PATCH 244/276] fix: legacy Bot Mode section in SOUL.md no longer
 taxes every session or shadows the live roster

Older desktop builds appended a frozen "## Messaging other agents" section (roster
included) to SOUL.md. Since the server started injecting the live section into Bot Chat
sessions, that copy did two wrong things: every CLI/TUI/messenger session paid ~600 tok
for a bot-only protocol, and in Bot Chat itself the probe went silent when SOUL carried
the heading, so bots saw the stale roster instead of the live one.

- load_soul_md strips the legacy section at read time (covers un-migrated profiles and
  the ambient-home edge cases the same way the SOUL isolation fix does)
- bot_mode_probe drops the SOUL-carries-heading suppression; a SOUL-era stored Bot Chat
  prompt now counts as legacy and is upgraded once (stamped, so it cannot loop)
- config migration v41 rewrites SOUL.md across the default + every profile once

Subject: [PATCH 246/276] refactor(mcp): keep the passive status RPC, drop the
 SDK contract and reason codes

mcp.servers.status now rides the shared _mcp_rpc decorator (profile scope, 4064,
5024 with the real message) instead of a hand-rolled try/finally with a blanket
except. Drop the _MCPConnectErrorText str subclass and reason taxonomy: the
existing status/error fields already carry the state, and a whitelist on the RPC
keeps error text out of the wire. The Desktop connections.health contribution
contract is held back until its consumer plugin is public. Tests trimmed to the
scope invariants (per-profile runtime visibility, scoped shutdown clears only its
own status, launch runtime never leaks into another profile).

Subject: [PATCH 248/276] fix(compression): anchor codex app-server preflight
 on reported usage

The codex_app_server runtime bypasses the conversation loop, so the
usage-anchored context accounting captured there never ran: agent._usage_anchor
stayed None forever. Every preflight estimate therefore fell back to the rough
mirror-transcript heuristic, which is deliberately never compacted on this
runtime (_record_codex_app_server_compaction preserves the mirror), so it grows
monotonically while the real thread may be tiny or freshly compacted. With
compression.codex_app_server_auto=hermes that estimate alone tripped the
threshold and fired thread/compact/start on nearly every turn of a long-lived
session (#100381).

Mirror the main loop's post-response capture: _record_codex_app_server_usage
now snapshots the reported thread usage into agent._usage_anchor (base prompt
+ completion exactly as the provider counted them, with estimation confined to
messages appended since). A usage-less turn keeps the previous anchor, and the
post-compaction invalidation site is unchanged.

Subject: [PATCH 249/276] feat(compression): usage anchor survives DB reloads
 and process restarts (salvage #99585)

The usage anchor (real usage.prompt_tokens + delta estimate of what was appended since)
identified the priced transcript by id() of the last message, so it was None on EVERY
gateway turn (history is re-read from the DB each turn) and in every fresh process
(--resume, desktop per-turn serve). Those are exactly the surfaces where the bytes/4
estimate then fired local compression against payloads the provider priced far under
threshold (#99421, #104462).

- agent/usage_anchor.py owns the anchor: content fingerprint instead of id(), persisted on
  the session row (model_config._usage_anchor) via set_usage_anchor(), restored on the first
  resumed turn while the durable transcript still matches, cleared with the row on
  compaction / codex-native rewrite / session reset.
- Callers repointed from model_metadata (the compat table follows).

Design and persistence slot from #99585 by @686f6c61; re-authored against the Sep 2026
layout (the branch predates the model_metadata / agent_init split).

+An anchor = provider usage at capture + a snapshot of the transcript position it priced:
+``base_count`` (len(messages) at capture; the reply is not yet appended and is covered by
+``completion_tokens``, so the delta walk skips an assistant row at that index), ``base_last_role``
+and ``base_last_fp`` (content fingerprint of the last priced message; compaction, splices and
+rewinds replace it → anchor fails closed → full estimation until the next real reading).
+
+The fingerprint (not ``id()``) is the identity: the gateway re-reads the transcript from the DB
+every turn and a resumed session runs in a fresh process, so object identity is never stable
+across the surfaces where the estimate mattered most (#99421, #104462). The anchor also persists
+on the session row (``model_config._usage_anchor``) so a restarted process can restore it; a
+restored anchor is honored only while the durable transcript still matches its fingerprint.

Subject: [PATCH 250/276] refactor(compression): every compaction gate asks
 real usage first; rough estimates only decide whether to wait
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two parallel "real usage" mechanisms fought each other: the usage anchor (real + delta) and the
compressor's rough/real projection (should_defer_preflight_to_real_usage with
last_rough_tokens_when_real_prompt_fit / _pending_request_rough_tokens / note_request_rough_estimate
baselines). The projection stored an anchored, real-scale figure as its "rough" baseline, so a
rewind that invalidated the anchor produced phantom growth and a spurious compaction (#103391).

Now there is one authority:

- Post-tool gate (turn_preflight.compress_after_tool_results): anchored figure first (the raw
  last_prompt_tokens ignored the tool results just appended), then real, then rough.
- Gateway hygiene (run_turn._hmwa_hygiene_plan): real session count, else the anchor persisted on
  the session row, else rough.
- Preflight / pre-API gates: an anchored figure is never deferred. A whole-context rough estimate
  over threshold waits ONE request for the provider's real count instead of compressing on a guess
  (first request, rewind/edit-resend, reloaded history without a persisted anchor).
- The wait is one request, never a disable: a provider that omits usage
  (note_usage_less_response, #2153 class), a real reading already over threshold, a rough figure
  past the whole window, and provider-proven overflow all compress immediately; the post-compaction
  latch (#36718 / #104192) is unchanged.
- Projection baselines and their bookkeeping deleted (-101 LOC in context_compressor); the fixtures
  that scripted whole-history estimates now state the fact they relied on (provider omits usage).

Fixes #103391 (closes #103397 by construction — the baseline it repaired no longer exists).

Subject: [PATCH 251/276] fix(compression): opaque encrypted_content costs 0 in
 every local token estimate

Codex Responses reasoning and compaction items carry ciphertext the provider prices by its own
token count, never by bytes; a single native compaction checkpoint is ~5M chars, which the
bytes/4 estimator turned into ~1.29M "tokens" against a 204K threshold (#100611). #104192 deferred
that decision for one request; this removes the mis-pricing at the source so the preflight
estimator and the tail-budget walk agree (a mismatched size class protects blob-heavy rows as
"small" and compaction re-fires). Only real usage prices these items, and the usage anchor carries
that price forward.

evals/native_compaction/ab_checkpoint_preflight.py: preflight estimate after checkpoint
1,292,413 -> 58 rough tokens; the over-threshold negative arm still compresses.

Subject: [PATCH 252/276] docs+evals(compression): token-accounting replay
 harness and developer-guide section (#104462)

evals/token_accounting/replay_gates.py runs the REAL AIAgent turn loop against a local fake
chat-completions server with scripted usage.prompt_tokens, in three shapes (CLI same-object
history, gateway JSON-reloaded history, SessionDB close/reopen + fresh agent) x two arms
(transcript 3x threshold by bytes/4 while real usage is under; transcript tiny while real usage is
over). Acceptance: no gate fires when real usage is under threshold regardless of estimate
inflation; every gate fires once real usage is over.

origin/main 5f406d88ea: cli/gateway/restore inflated all FAIL (1 local compaction each on the
estimate). This branch: 6/6 PASS, anchor restored in the fresh process.

+"""Token-accounting replay: do the compaction gates follow the provider's REAL usage or the
+local ``bytes/4`` estimate? (#104462)
+
+Runs the REAL ``AIAgent`` turn loop against a local fake OpenAI chat-completions server whose
+``usage.prompt_tokens`` is scripted per request and deliberately disagrees with the transcript
+size. The only patch on the agent path is a counting wrapper around ``_compress_context``
+(the question is *whether* a gate fires, not what a summarizer writes).
+
+Shapes (each runs several turns):
+
+* ``cli``      — same history list objects across turns (CLI REPL).
+* ``gateway``  — history JSON round-tripped before every turn (fresh dict identities, as the
+                 gateway re-reads the transcript from the DB each turn).
+* ``restore``  — turn 1 persisted to a real ``SessionDB``, DB closed/reopened, a FRESH
+                 ``AIAgent`` resumes (desktop per-turn ``serve`` / CLI ``--resume``).
+
+Scenarios per shape:
+
+* ``inflated``  — transcript ~3x the threshold by bytes/4, provider reports real usage well
+                  UNDER threshold. No gate may fire (positive arm).
+* ``deflated``  — transcript tiny by bytes/4, provider reports real usage OVER threshold.
+                  Local compression MUST fire once real usage is known (negative arm).

 system** that runs inside the agent's tool loop with access to accurate,
 API-reported token counts.
 
+#### Token accounting: real usage decides, the estimate only decides whether to wait
+
+Every compaction gate (turn-start preflight, idle, pre-API pressure, post-tool)
+asks the **usage anchor** first (`agent/usage_anchor.py`): the provider's last
+`usage.prompt_tokens` plus a rough estimate of ONLY the messages appended since
+that response. The anchor identifies the priced transcript by a content
+fingerprint, so it survives the gateway re-reading history from the DB every
+turn, and it is persisted on the session row so a fresh process (`--resume`,
+desktop per-turn `serve`) restores it while the durable transcript still
+matches. Compaction, session reset and codex-native compaction clear it.
+
+Without an anchor (first request, rewind/edit-resend) a whole-context rough
+estimate over threshold **waits one request** for the provider's real count
+instead of compressing on a guess (`should_defer_preflight_to_real_usage`).
+The wait is one request, never a disable: a provider that omits usage, a real
+reading already over threshold, a rough figure past the whole window, or a
+provider-proven overflow all compress immediately.
+
+Opaque provider blobs (`encrypted_content` on Codex reasoning / compaction
+items) contribute 0 to every local estimate; only real usage ever prices them.

Subject: [PATCH 254/276] refactor(memory): keep the spill, drop
 registration-trust rework

The prefetch spill is the fix; the is_builtin registration flag and duplicate-
instance rejection defended against a provider naming itself "builtin", which no
live path can do (only a test fixture does). Restore the name-based check and the
four test files that only changed for the new kwarg; keep two spill invariants.

Subject: [PATCH 255/276] feat(ci): public-surface diff vs base (dropped public
 names, methods, test defs), advisory on PRs

The Sep 2026 whole-codebase refactor (PR #102117) opened with 1,703 public
top-level names dropped across 341 modules, 1,000 public/dunder methods in
166, and 126 `def test_` deleted in 52 files. Reviewers found ~30 of the
names by hand; the rest surfaced as post-merge rework: 10 commits restoring
symbols and facade re-exports, 6 restoring tests, and a qwen OAuth break
that passed import smoke because the caller used `module.attr`. Every one
was catchable in seconds; nothing ran the check because it did not exist.

scripts/ci/check_public_surface.py: AST diff of modules present on both
sides of merge-base..HEAD. Public top-level names (defs, classes,
assignments, imported/re-exported names), public and dunder methods of
top-level classes, and `def test_` counts per tests/ file. Deleted modules
and deleted test files are visible decisions and are not flagged; private
names are not flagged. Advisory (exit 0, prints the report) by default;
--strict exits 1 so a refactor brief or a CI lane can gate on it. Wired
into lint.yml as an advisory PR step next to the compat-pointer check.

Replayed on the refactor PR at open (63279301bcb..022785a541) it reports
exactly the figures above in 18 s; on this branch vs main it reports 0.

Test: a throwaway git repo with drops, private drops, a move-with-re-export,
a lost test def and a changed non-source module; asserts the exact report
and the advisory/strict exit codes.

+"""Public-surface diff against a base ref: dropped public names and dropped test functions.
+
+The Sep 2026 whole-codebase refactor (PR #102117) opened with 1,703 public top-level names dropped
+across 341 modules, 1,000 public methods in 166, and 130 ``def test_`` deleted in 54 files.
+Reviewers found ~30 of the names by hand; the rest surfaced as post-merge fixes (10 commits
+restoring symbols/re-exports, 6 restoring tests, plus a qwen OAuth break that went past import
+smoke because the caller used ``module.attr``). Every one of those was catchable in seconds with
+this script; nothing ran it because it did not exist.
+
+Rules (deliberately narrow, no allowlist file to maintain):
+- A PUBLIC top-level name (function, class, module-level assignment, re-exported import) or a
+  public/dunder method of a module present on BOTH sides may be moved and re-exported or
+  deprecated, never silently removed. A deleted MODULE is not a drop here (that is a visible
+  decision; ``check_doc_paths`` territory).
+- A ``tests/**`` file present on both sides must not end with fewer ``def test_`` than it started
+  with. Deleting a whole test file is, again, a visible decision and not flagged.
+
+Advisory by default (prints the report, exit 0). ``--strict`` exits 1 on any finding so a
+refactor brief or a CI lane can make it a hard gate. Runs in ~30 s over the whole tree.

Subject: [PATCH 256/276] fix(ci): check_public_surface refuses unresolvable
 refs and does not flag methods extracted into an in-module base class

Independent review: a nonexistent base ref under --strict reported zero
drops and exited 0 (a mis-fetched CI job would look clean); the script now
verifies both refs and the merge-base and exits 2 otherwise. And a method
moved from a class into a mixin/base defined in the same module that the
class still derives from was reported as removed although the attribute
still resolves; public_methods now collects the methods REACHABLE on each
class through its in-module bases. Replay of #102117 at open: 1,703 names /
341 modules and 126 test defs / 52 files unchanged; methods 1,000 -> 951
(the 49 were in-module mixin extractions, i.e. the false positives).

Test: unresolvable ref -> exit 2 in both modes; a method extracted into an
in-module base is not reported.

Subject: [PATCH 257/276] ci(lint): deepen the shallow checkout before the
 public-surface diff; the step is advisory and never fails the job

The round-2 change made check_public_surface refuse to report a clean diff
without a merge-base (exit 2). That correctly exposed that the lint job's
depth-1 checkout plus a depth-1 fetch of the base has NO merge-base, so the
advisory step had been silently reporting 0 drops on every PR. The step now
deepens both sides until a merge-base exists and carries continue-on-error so
an advisory check can never block the Windows-footguns job it rides in.

 Memory providers are single-select — only one is active at a time, chosen via `memory.provider` in `config.yaml`.
 
+If a provider also loads as a general plugin, general discovery owns its lifecycle hooks. The memory loader supplies hooks only as a fallback until that same plugin source loads successfully through general discovery. Repeated provider loads replace the fallback hook group; distinct callbacks within the group are preserved. This does not deduplicate hooks from different plugin sources or change provider activation.

Subject: [PATCH 259/276] refactor(plugins): own dual-kind hook fallback in the
 ledger mixin

Move the general-vs-memory hook ownership logic out of the memory collector into
PluginLedgerMixin (_drop_fallback_hooks / _register_fallback_hook) so the collector
and the loader each call one manager method instead of reaching into manager privates.
Hoist hashlib to module scope. Trim the new suite to the three invariant cases
(run-once across load orders, distinct sources not suppressed, re-exported register).

Subject: [PATCH 260/276] feat(logging): the API call line carries cache write
 count, the provider's response id, and the serving upstream

Diagnosing the 1,393-agent run's cache misses took a state.db join and a live
probe because none of the three were on the one line we log per call:

  write=<n>    cache_creation tokens; a write costs 50x a read, so this is the
               money, and "read stuck, write large" on consecutive lines is a
               routing miss visible without a probe
  id=<id>      the provider's response id (Anthropic msg_..., OpenRouter/Nous
               gen-...): what a provider needs to look a request up
  upstream=<n> who actually served, when the route reports it (OpenRouter's
               `provider`); how we learned GMI was not serving

Fields are appended to the existing line and omitted when absent, so every
existing parser (evals/postmortem, the two cache_prefix probes) keeps
matching; the forensics parser reads them when present.

The streamed chat path fabricated `id="stream-<uuid>"` and dropped the
chunks' id/provider on the floor; it now keeps the first chunk's id and
provider, falling back to the fabricated id only when the stream never sent
one. Nothing depended on the prefix.

Live (Nous, Fable 5.1, both wires): chat -> `write=3759
id=gen-1788727882-... upstream=Anthropic`; native -> `id=gen-1788727891-...`
(the Anthropic Message object's id was already real). Tests: fields present
and omitted, prefix unchanged; forensics parser reads new and old lines.

Subject: [PATCH 262/276] feat(compression): per-image token cost learned from
 the provider's own usage (#70328, supersedes #70463)

A flat per-image constant (1500 in the trigger estimator, 1600 in the tail-budget walk) is wrong in
both directions: a screenshot costs ~1,100 tokens on one provider and 4,000+ on a local mmproj
model. In a GUI loop on a 64K window the estimate sat at ~20K while the real prompt passed 80K,
so compaction never fired and the provider rejected every request (#70328).

The provider prices every image exactly on the request that carries it, so the cost is
observable from usage alone, with no vendor formula: with a fresh usage anchor, the residual
between the next real prompt_tokens and anchor + text-only delta is the price of the N images
that delta introduced.

- agent/image_token_cost.py: calibrate_from_usage() runs in record_response_usage before the new
  anchor is captured; the learned value (EMA, plausibility-banded) is kept per model@host in
  ~/.hermes/cache/image_token_costs.json and bound per turn through a ContextVar.
- estimate_messages_tokens_rough, _content_length_for_budget (tail walk) and gateway hygiene all
  read the same bound value, so trigger and walk agree; the per-message memo now caches text
  tokens and image COUNT so a recalibration re-prices cached rows.
- One flat default (1500) remains only until the first vision turn; the duplicate 1600 is gone.

evals/token_accounting/ab_image_cost_calibration.py (real AIAgent, fake provider pricing images
at 4,000, one screenshot per turn, 64K window): main learns nothing (1500) and the tail walk
under-prices its own protected tail by 56.5%; this branch learns 4,374 after one vision turn
and the walk's error is +8.5%.

Subject: [PATCH 263/276] fix(chat-completions): strip name from tool-result
 messages for strict providers

The Chat Completions schema has no `name` field on `role: tool` (only on
the long-removed `role: function`), but Hermes carries the tool name over
onto the result message. Permissive providers ignore it; strict ones
(aki.io) reject the whole payload with `contains item with unknown key
name`, which breaks every tool call in the session.

Follow-up to the review on #51365:

- The strip now goes through the copy-on-write `mutable_msg()` path in
  `convert_messages()`, preserving the identity/copy-on-write contract
  instead of mutating `msg` in place.
- `handle_max_iterations()` hand-builds its summary payload and calls
  `chat.completions.create()` directly, bypassing the transport, so it
  leaked `name` even with the transport fixed. It now mirrors the same
  role-qualified removal, next to the existing tool_name/codex_*/timestamp
  strips.

The removal is role-qualified: `name` stays on user/assistant messages,
where it is schema-valid.

Regression coverage on both paths; both tests fail without the fix.

Subject: [PATCH 264/276] fix(agent): stale-call watchdog prices images at the
 learned per-image cost, not base64 length (salvage #76471)

estimate_request_context_tokens (the stale-stream / non-stream watchdog and Codex TTFB floor
estimator) did len(str(payload)) // 4 over the wire payload, so one native screenshot read as
~100K tokens and selected the 1200s giant-conversation floor while the provider's real prompt
was ~2K (#63871, #76411). Image content parts on both wire shapes (Chat image_url / Responses
input_image) now cost the per-image price learned from provider usage (agent/image_token_cost,
bound per turn; worker threads inherit it via copy_context); base64-looking STRINGS stay text
and tool schemas mentioning image are not images.

A/B, one 300KB screenshot: main estimate 100,545 -> codex floor 1200s / stale 300s; now 2,025
-> floor 0s / stale 180s.

Design and boundary (structured parts only, tools/instructions opaque, plain data-URL strings
stay text) from #76471 by @crdesign8; re-authored to reuse the learned cost instead of a second
fixed constant, and trimmed to 2 invariant tests.

Subject: [PATCH 265/276] fix: gpt-6 Astra on Codex OAuth gets the 85%
 compaction autoraise

Codex OAuth caps gpt-6-astra at the same 272K window as gpt-5.4/5.5/5.6,
so the global 50% trigger compacted at ~136K. Extend the existing
codex_gpt55_autoraise gate to any slug containing "astra" (minus the
opt-in -900k picker variants, which already unlock the wider window).
Other routes (OpenAI direct, OpenRouter) keep the user threshold.

 ## Behavior details
 
-- **Idle-only.** A heartbeat never interrupts a running turn. If the agent is busy when the tick comes due, it fires at the next idle poll.
+- **Idle-only.** A heartbeat never interrupts a running turn. If the agent is busy when the tick comes due, it fires at the next idle poll. In the gateway, an idle watched session wakes proactively; no new inbound message is needed.
 - **Missed ticks coalesce.** If the session was busy (or the process wasn't running) through several intervals, you get **one** heartbeat turn, not a backlog. The timer re-anchors on every fire.
 - **User messages win.** A queued user message always takes priority; the heartbeat waits for the input queue to drain.
 - **Cache-safe.** The injected prompt is an ordinary user message. No system-prompt mutation, no toolset change.

Subject: [PATCH 269/276] docs(kanban): name the legacy-attachments cutoff
 (#35395) in the type comment

Desktop AGENTS.md requires a compat fallback to be 'tied to an identified
older runtime' so a future cleanup knows when it can be deleted. The
original comment said only 'older backend plugins'; name the actual
boundary: backends before #35395 (May 2026) omit the attachments key.

Review follow-up on the salvage of #104529.

Subject: [PATCH 272/276] refactor(plugins): share the hook-token release
 between runner and start-failure paths

The identity-guarded token pop appeared twice (the runner's finally and the
new worker-start except); a future edit to one copy would silently reintroduce
the sticky-token class. Hoist into a local closure called from both sites, and
extend the _run_hook_callback_bounded docstring with the new skip reason.
Behavior-preserving follow-up on #104651.

Subject: [PATCH 273/276] fix(agent): tolerate schema-valued "type" keys in the
 watchdog payload estimator (#104793)

The image-part membership test in _payload_chars() ran on every dict in
the request, so a tool JSON Schema with a parameter named "type" (its
value is the sub-schema dict) or a multi-type value like
["string", "null"] raised TypeError: unhashable type before the
request reached the provider. Guard the membership test with
isinstance(str): structured "type" values are payload data, not
content parts, and keep the legacy walk for them.

Subject: [PATCH 274/276] refactor: share CLI goal commands across interactive
 surfaces

Keep parsing, contracts, gates and persisted goal mutations in one dispatcher. Adapters retain authorization, rendering and scheduling; TUI drafting resolves the target session profile off the RPC reader. Document ACP as unsupported rather than implying a goal loop exists.

-Works identically on the CLI and every gateway platform (Telegram, Discord, Slack, Matrix, Signal, WhatsApp, SMS, iMessage, Webhook, API server, and the web dashboard).
+The classic CLI, TUI, Desktop, dashboard chat, and messaging gateway use one shared `/goal` command handler. This includes draft/show, inline contracts, wait/unwait, quality gates, and the clear/stop/done aliases. Desktop goal controls use the same handler, too. ACP does not currently advertise or implement `/goal`.
+
+`/goal draft <text>` both creates the goal and starts its first turn, including when drafting is unavailable and Hermes falls back to a free-form goal. `draft` is a whole-word subcommand: `/goal drafting docs` keeps `drafting docs` as the literal objective without calling the draft model.
+
+Messaging platforms retain their access rules: `/goal gate add` requires an explicitly configured gateway admin; listing, removing, and clearing gates remain available for recovery. Rendering and turn scheduling are surface-specific, but command parsing and persisted goal changes are shared.
