Under #92021 the scanner no longer emits critical agent_config_mod /
hermes_config_mod findings for bare mentions - the migration script's
legitimate references now score as informational _ref findings and the
verdict is "safe" with zero modification-intent findings. Tighten the
assertion accordingly (verdict must be safe, not merely non-dangerous)
and swap the known-false-positive set to the new _ref ids.
The skills-guard-v1 scanner flagged ANY mention of AGENTS.md / CLAUDE.md /
.cursorrules / .clinerules as critical/persistence. Any critical finding
forces a dangerous verdict, and community installs cannot be overridden
with --force — so legitimate meta-skills that merely DISCUSS agent config
files (authoring guides, setup docs, cross-references) were permanently
blocked. Three popular community skills were hit in the wild.
skills-guard-v2 scores the persistence category in three tiers:
- Mechanical persistence (shell redirection or sed -i targeting an agent
config file) stays critical -> dangerous. An unambiguous write path.
- Modification language in imperative position (verb at line/bullet start
within 80 chars of the filename) is high -> caution. Regexes cannot
separate "Edit AGENTS.md to inject instructions" from descriptive prose,
but imperative verbs are the shape real instructions take. Caution keeps
the install confirmable instead of irreversibly blocked.
- Bare references drop to low/informational for auditability without
driving the verdict.
The verb-proximity shape matches the existing convention in
tools/threat_patterns.py, and the tiering mirrors how allowed_tools_field
was already handled. The pattern id agent_config_mod is preserved so
plugin_guard.CODE_EXEMPT_PATTERN_IDS stays valid; hermes_config_mod /
other_agent_config get parallel _shell / _ref splits fixing the whole bug
class. SCANNER_VERSION bumps to v2 so cached v1 dangerous verdicts are
invalidated and re-scanned on next install attempt.
* fix(execute_code): limits line teaches spillover — big stdout is saved, not lost (follow-up to #97043)
* fix(execute_code): drop the editorializing tail from the limits line (maintainer review)
* refactor(execute_code): integrate kernel persistence into the core description (712 -> 654 tok/call, -8%)
* fix(execute_code): honest interpreter note — Hermes's own python is the common case; project venv only when VIRTUAL_ENV/CONDA_PREFIX is active
Drives the REAL session.resume -> _make_agent -> AIAgent path (eager_build)
through tui_gateway.server.handle_request against a real seeded state.db in
an isolated HERMES_HOME — no mocks. Three scenarios from the live report:
deleted provider falls back to default, renamed provider heals, and a legacy
canonical Bot Chat (no follow_profile_config marker) follows the profile's
current config.
A/B verified: all 3 FAIL on origin/main with the reported
"resume failed: Unknown provider '<name>'"; 3/3 pass with the salvaged
fixes + backfill.
Bot Chats created before the follow_profile_config marker existed carry no
contract in model_config, so they would stay pinned to a stale stored
provider until deleted — the exact shape of the live reports (#89497,
#94818). Mirror the plugin's own identity rule (the profile's session
titled exactly 'Bot Chat') as a legacy fallback in
_stored_session_runtime_overrides, matching the room-plumbing legacy
'Group:' title fallback.
Follow-up to the salvaged #90343 (@curator8888) and #96111 (@lorzl).
Bot-Mode canonical chats (the ONE forever DM per bot) and room plumbing
sessions are plugin-owned scratch conversations. They are now created with
an explicit follow_profile_config contract, persisted in the session row's
model_config, so session.resume rebuilds from the member profile's CURRENT
config instead of restoring the stored model/provider pin from an old row.
That stale pin is what left bot DMs stuck on a dead provider (e.g. 'out of
Nous credits' after the profile was switched to ollama-cloud) while the
same bot worked fine in rooms — the mirror image of the room-plumbing bug
(#89497 class). Normal 1:1 user chats keep the stored-runtime restore:
opening an older chat must show the model it actually used.
- tui_gateway/methods_session.py: accept follow_profile_config on session.create
- tui_gateway/server.py: persist the marker in the row; skip stored-runtime
overrides on resume when present
- apps/desktop/src/plugins/hermes-bots/plugin.js: send the contract from
createCanonicalChat and ensureGroupChatSession
- tests: backend override + row-persist coverage; desktop source-contract
coverage for both session kinds
Room member sessions in Bot Mode are per-member scratch conversations
inside a group chat. session.resume restored their stored model/provider
pin from the row's model_config, so a room bot stayed stuck on whatever
provider was pinned when the row was first written — even after the
profile was switched. Every room message then failed on the stale
provider (e.g. 'out of Nous credits' after switching a profile from
Nous to ollama-cloud) while the same bot worked fine in DMs.
Add an explicit room_plumbing contract:
- session.create accepts room_plumbing: true, persisted in model_config
- _stored_session_runtime_overrides() returns {} for marked rows, so a
room session always rebuilds from the member profile's CURRENT config
- hidden + 'Group:' title shape is kept as a legacy fallback for rows
created by older desktop builds that never sent the marker; hidden
non-room chats keep the stored-runtime restore
- Desktop Bot Mode sends room_plumbing: true when creating the hidden
per-member room sessions
Fixes#89497
A session row persists the provider identity a chat actually used. When that
provider is later renamed or removed (e.g. a custom_providers:/providers:
entry deleted, or a provider renamed oldone->newone), Desktop/TUI resume
restores the stale name into agent init and dies with:
agent init failed: Unknown provider '<name>'
while the CLI resumes the same session fine with the configured default.
- runtime_provider: add is_routable_provider() (full resolution chain:
built-in -> providers: -> custom_providers: -> models.dev)
- _stored_session_runtime_overrides: heal a non-routable provider via
canonical_custom_identity (base_url -> model -> configured provider),
drop to the configured default when unrecoverable, and clear the stale
base_url after healing so a dead endpoint cannot override the registry URL
- _start_agent_build: gate deferred-resume overrides on provider routability;
when the stored provider is gone, prefer the model the user picked for THIS
session, else the configured default
- tests: is_routable_provider cases, heal/fallback round-trips, gate checks
Refs #75128
Test-pollution class: runtime_provider is usually imported lazily (inside
switch_model's resolution path), so its first import in a pytest worker can
happen while a test has hermes_cli.config.load_config patched. The
module-level from-import then bound the MagicMock permanently — after the
patch exited, every later caller in the process silently read the dead
test's config. Live victim: MoA aggregator context-length resolution
(resolve_runtime_provider -> AuthError 'Unknown provider custom:example'),
making TestMoAContextLength::test_moa_custom_context_configures_compressor_threshold
fail whenever it shared a process with
TestLocalOllamaModelDiscovery::test_switch_model_on_current_ollama_custom_endpoint_keeps_base_url.
Fix: load_config / get_compatible_custom_providers / normalize_extra_headers
become late-bound delegates resolving hermes_cli.config attributes at call
time. Both patch targets (config.load_config and
runtime_provider.load_config) keep working. Regression tests pin the
late-binding property and fail if the delegates revert to from-imports
(sabotage-verified).
Live on both providers (verified 2026-08-28 against openrouter.ai/api/v1/models
and inference-api.nousresearch.com/v1/models) but absent from both curated
picker lists. Adds the entry directly below qwen3.8-max per newest-first
family ordering, an explicit 1M DEFAULT_CONTEXT_LENGTHS entry (new family
slug would otherwise fall through to the generic qwen 131072 catch-all —
same class as #69881), and regenerates model-catalog.json.
Scoped rollout: only the named providers touched. Pricing snapshot skipped
(both routes bill via official_models_api live pricing). Reasoning floor
already fires via the qwen3 prefix entry (180s, verified).
Check both resolved and unresolved path parts so a symlinked named
profile (e.g. profiles/dev -> /mnt/data/dev) is still detected.
Also use _ensure_cron_dir for output_dir in ensure_dirs() for consistency.
Simplify-code Phase 2 finding (medium severity).
Replace #96637's inline active_profile_homes() closure with #96508's
module-level _existing_profile_homes() filter (testable in isolation).
Widen _ensure_cron_dir from 3 to 12 mkdir sites across cron/ so every
directory creation fails closed for deleted named profiles, not just
the 3 originally protected. Add _is_named_profile_path() that checks
'profiles' in path parts (works for subdirs like cron/output/<job> and
scripts/ that the original parent.name heuristic couldn't reach).

_call_llm_impl applied auxiliary_max_tokens_param whenever
fast_compression_cap was non-None — but _compression_fast_lane_controls
passes an explicit caller max_tokens straight through, so a compression
call that set its own cap had the param force-injected onto providers
where _build_call_kwargs deliberately omits it (ZAI vision hard-400s on
max_tokens; GPT-5/Copilot require max_completion_tokens). Pre-fast-lane
main omitted the param for that exact call shape (verified via
subprocess pinned to the pre-PR base).
Gate the forced param on 'max_tokens is None' so it applies only to caps
the certified lane itself produced — the same guard the fallback path
already uses.
Regression test pins the pre-PR wire shape. Mutation-checked.
_run_protected_sync_provider_call propagates the forward-progress hook to
its daemon worker but not the new _aux_dispatch/_aux_provider_response
timing hooks (both threading.local). When compression takes the protected
path — the common case, since the summary call runs under
aux_interrupt_protection with a hard-cancel source — provider_dispatch_ms
and time_to_first_progress_ms were silently absent from telemetry.
Also collapse the two byte-identical save/restore context managers
(aux_progress_hook, _aux_timing_hook) onto one _aux_thread_local_hook
implementation so the propagation semantics can never drift between the
progress and timing slots.
Regression test drives _run_protected_sync_provider_call with both timing
hooks installed and asserts the worker-thread notifies reach them.
Mutation-checked (reverting the propagation fails the new test).
Post-review hardening on the attempt-ownership commit:
- Write-time re-validation: the entry staleness check in
_restore_compressor_attempt_state runs before the durable-cooldown DB
I/O, so a fallback could claim the compressor in that window and the
stale setattr loop would still clobber its state. The in-memory writes
now re-validate AND execute under _COMPRESSOR_ATTEMPT_LOCK — the same
lock claims are taken under. The DB rollback stays outside the lock
(safe: the dangerous direction requires a prior claim, which the entry
check rejects). Both the quality reviewer and the lead's independent
pre-verification converged on this window.
New deterministic test: TestMidRestoreClaimRace (claim injected
between entry check and write via instrumented deepcopy).
- Documented gen-0 semantics on _claim_compressor_attempt: per-compressor
all-or-nothing, never mixed with gen>0 on one instance (reviewer
finding 2, verified unreachable — comment hardens against future
confusion).
Dropped after verification (reviewer finding 3): resetting
_SUMMARY_ROUTE_CONSUMED on pin_summary_route exit — the echo lives in
the worker thread's COPIED context (propagate_context_to_thread) and
dies with it; a probe confirmed the next attempt's context is clean.
Resetting it would break digests running after the with-block.
Follow-up to #96634 (stall-fallback retry, #78981) addressing
donovan-yohan's post-merge adversarial review. The stall path detaches a
timed-out primary worker (fence cancel wins; future stays on the pool)
and immediately runs the fallback against the SAME ContextCompressor,
creating two verified races:
1. Late-primary snapshot restore: the detached primary's unwind called
_restore_compressor_attempt_state with the PRIMARY's pre-attempt
snapshot. Landing after the fallback's commit it rolled
_previous_summary/cooldown/provenance/telemetry back to pre-primary
values, silently discarding fallback-owned state.
2. Shared _compression_cancelled_check: the late primary's `finally`
cleared the callback the fallback had just installed, so the
fallback's F4 cancellation consult read None.
Fix: a monotonic per-compressor attempt generation claimed under one
module lock (_claim_compressor_attempt). Snapshot restores carry their
claiming generation and no-op when stale; the cancelled-check set/clear
moves into owner-stamped helpers (_install_compression_cancelled_check /
_clear_compression_cancelled_check_if_owner) so only the installing
attempt can clear it. The commit fence keeps owning COMMIT admission;
the generation owns compressor-ATTRIBUTE writes — two boundaries.
Legacy callers (attempt_generation=None) and slotted third-party
compressors (generation 0) keep the historical unconditional behavior.
Secondary review items:
- Lean chunk digests during a stall-fallback retry now follow the
summary onto the pinned healthy route: take_pinned_summary_route()
echoes the consumed route into a context-local
_SUMMARY_ROUTE_CONSUMED, and _build_chunk_digests passes
attempt_summary_route_kwargs() (non-consuming) to call_llm. The pin's
single-use contract for the SUMMARY call is unchanged — the
main-model retry still never re-issues the pinned route.
- Worker re-run repeating pre-compression callbacks: documented as an
accepted limitation on _retry_compression_on_fallback_chain
(built-ins idempotent; resuming mid-pipeline would couple the retry
to host callback ordering).
Tests (tests/agent/test_compression_attempt_ownership.py, 10 cases):
deterministic interleavings for both races (late-primary restore
no-ops + preserves fallback state; stale finally cannot clear the
fallback's callback), legacy/slotted compatibility, digest route
follow + context-locality of the consumed echo. Mutation-checked:
reverting only the two prod files to origin/main fails the suite;
restored stack green (21 passed incl. the original #78981 suite).
The one red in the wider sweep
(test_silence_cannot_approach_double_idle_timeout) is pre-existing on
clean origin/main — verified independently.
resolve_compression_fast_lane and _compression_config_claims_fast_lane
each hand-parsed the same four config fields (provider, model,
reasoning_effort, max_output_tokens) with copy-pasted normalization and
int-coercion. Extract _fast_lane_config_fields() as the single source of
truth for both.
This also fixes a real inconsistency the duplication hid: certification
checked the literal string 'none' while _get_task_extra_body routes
reasoning_effort through parse_reasoning_effort, which treats 'false',
'disabled', and YAML boolean false as disabled too. A user writing
reasoning_effort: false got reasoning disabled but silently lost the
fast-lane cap. Certification now delegates to parse_reasoning_effort so
the two predicates can never disagree.
Regression test: every disabled-spelling certifies; empty/real efforts
do not. Mutation-checked (reverting to the literal check fails the new
test).
_compression_fast_lane_controls unconditionally did body = dict(extra_body)
before the early-return guard. Move the copy below the guard so non-
compression auxiliary calls (vision, title_generation, etc.) return the
original extra_body reference without a shallow copy.
The contributor's PR description notes this commit was deliberately
omitted as obsolete. Removing the planning doc that was accidentally
included via cherry-pick.
PR review (andrexibiza, post-a69a9c351d) caught the one operator-facing
surface the identity change missed: the example config still promised
the profile-scoped ID is NOT sent and described the 30-day rotating
HMAC. Rewritten to state the stable install_id is transmitted as-is,
matching the sender, wizard, and docs A.2. Swept the repo for further
stale references: none remain (the HMAC text in relay-shared-metrics.md
A.2/A.3 is the intentional decision record).
Three-reviewer pass (reuse/quality/efficiency) on the guard file:
- Drop dead `agent._interrupt_requested = False` setup: the
`_record_streamed_assistant_text` chain only consults
`_stream_writer_superseded()` (stream-writer TLS token), never
`_interrupt_requested` — verified by reading both call sites.
- Deduplicate the two trace-callback blocks into one
`_count_writer_statements` helper using the house idiom
(`statements.append` — 9 existing uses in tests/test_hermes_state.py)
instead of a mutable-dict counter closure; failure messages now dump
the captured SQL for direct diagnosis.
Dropped after verification: reviewer suggestion to flip xfail to
strict=True — its premise ("the fix PRs already remove the markers")
is wrong: #92166/#95380 predate this file and cannot remove markers
they don't contain, so strict=True would redden main's CI the moment
either merges. strict=False + follow-up marker removal is the
deliberate no-red-window ratchet.
Efficiency reviewer: no material findings (GC delta 0.06 on the ratio,
36.9MB peak, sqlite trace API stable since 3.14, dir convention OK).
Re-verified post-fold: 3x main runs (2 passed, 2 xfailed), flip checks
on both fix branches still pass with --runxfail.
Pattern B (O(N²) rebuild-per-delta in hot paths) has no lintable
signature, unlike Pattern A's ASYNC ruff gate: `s += frag` is quadratic
in a hot loop and harmless elsewhere. The only durable prevention is
behavioral — pin the scaling SHAPE of each known hot path and fail CI
when it regresses.
New tests/perf_guards/test_pattern_b_scaling.py, three guards:
1. Streamed-text accumulation (fix in flight: #92166)
Self-normalizing ratio: time at 16k deltas over 4k deltas.
Linear ≈ 4x, quadratic ≈ 16x; main measures 9.6x → strict bound 7.0.
xfail on today's main, PASSES on the #92166 branch (verified).
2. list_sessions_rich statement count (fix in flight: #95380)
Deterministic — counts writer-connection SQL statements via sqlite
trace callback, zero timing. Bounded-constant guard xfails on main
(measured N+1: 26 stmts / 12 sessions), PASSES on #95380 (verified).
A second, weaker budget guard (≤4·N+8) passes TODAY and catches a
regression from N+1 to N·M immediately.
3. Tool-call fragment assembly (#92242 shape)
Ratio guard on the buffered-parts accumulator model; sized so the
small case takes ≥3ms (sub-ms bases jitter on CI runners).
Flake hardening: min-of-K timing, ratio thresholds with ≥2x separation
from both measured-good and measured-bad, operation counts preferred
over timing. 10/10 identical outcomes across repeated local runs.
The xfail markers are the ratchet contract: each names its fix PR and
must be removed when that PR merges, flipping the guard to enforcing.
* refactor(code-execution): retire kernel_mode — session kernels always on for local runs (remote per-call is a tracked gap, not a mode)
* test(code-execution): env-filtering probes use reset=true — kernel env is frozen at spawn, so env rules are only observable on a fresh kernel
* test(code-execution): kernel-aware fixes for mode/pythonpath suites — reset=true on frozen-at-spawn probes, per-test kernel disposal, abort-after-capture fake Popen
* test(code-execution): strict-mode cwd is a behavior contract (staging tmpdir, not session cwd) — kernel stages in hermes_kernel_*, per-call in hermes_sandbox_*
Product-owner decision, 2026-08-27: the analytical need is stable
cross-window identity (retention curves, longitudinal install
behaviour), which the rotating pseudonym destroyed by design. The
feature has not shipped - zero consented users, zero production
transmissions - so identity semantics can change without breaking any
promise made to a user; existing (dev-only) consent windows carry
forward unchanged.
Removed in full rather than weakened in place:
- shared_metrics_identity.py (salt generation/rotation, HMAC-SHA256
derivation, payload substitution) and its 19-test file.
- The sender's derivation step. _freeze_identity keeps its validation
role (unreadable/non-object/id-less payloads still reject rather than
block the queue) and now records the raw install_id in
sent_install_id; _body rewrites the payload's install_id from that
frozen column, keeping byte-identical resends anchored to one
recorded value.
Consent surface updated in the same change: the setup wizard now states
plainly that packages carry the stable profile-scoped install ID (a
random UUID, no personal information, reset by deleting the
shared-metrics directory). No consent was ever collected under the old
wording in any shipped build.
Docs A.2/A.3 rewritten as decision records rather than silently
edited: A.2 records what is transmitted now and states the
consequences plainly (indefinite cross-package correlation is the
designed behaviour); A.3 records why rotation existed and why its
removal was accepted. The main-body "must not reuse the persistent
local identifier by default" escape hatch is exercised, not deleted:
that paragraph required exactly this product decision, which has now
been made. A.6's deletion note updated: install_id is now itself the
lookup key, so a future delete-on-request needs only a service-side
API, not a mapping.
Tests: the two privacy assertions invert deliberately
(test_the_stable_install_id_is_transmitted_as_is and the e2e wire
variant); freezing/byte-identical-retry coverage unchanged. Staging
E2E script now asserts transmitted == install_id.
258 targeted tests pass; ruff + footguns clean; both staging E2E
harnesses green with the raw id observed on the wire (202s).
The English bundle on the parent left the other locales to fall through.
Ship them the same way kanban does, using core's nouns, so a language
switch no longer paints the Bots rail in English.
Deleting the Bots home deleted the dead end that "Select a Bot or group
first." was apologizing for: with nothing selected the center is now an
ordinary session and + works there. The refusal still stands for the cases
that remain — a group room, and a selected row too orphaned to route.
Ownership of an empty transcript is per session and is not known until each
plugin has loaded its own data — which is why the slot mounts contributors
rather than resolving a claim up front. Taking only contributions[0] then let
a plugin that DECLINES a session suppress the one that owns it: silently,
permanently, and only for the users whose installed plugins happen to
register in that order.
Every registration is mounted and answers for itself. Declining is free; two
claiming one session render both, a visible conflict instead of a silent drop.
The composer subscribed to $sessionStates while isBotChatSession reads the
scope set — and, to resolve a live id to the stored one it is filed under,
$sessionTiles too. It stayed roughly right only because $sessionStates
republishes per streaming token, so the stale answer was overwritten within a
frame. A quiet session had no such luck.
Adds useStoresSelector beside useStoreSelector for the general case: a scalar
whose inputs span several stores, recomputed when any notifies, still
re-rendering only when the scalar changes.
The migration, its commit marker, and the rollback around it are all still
live in data.ts, but the suite covering them went out with the vm/regex
harness and was never ported — leaving only the happy-path commit ordering
asserted incidentally by bot-delete.
Nine cases: the sole-local topology gate (and the two refusals — multi-source,
and a batch where any one profile has no local route), the marker rule that
makes v2 authoritative (committed, markerless, crash-window), and the three
failed-commit paths (roll back to the last committed generation, clear both
keys when there is none, survive a failed cleanup).
migratedLocalRoutes is module-private, so where the old suite asserted the
map's size this one asserts what the map is for: no route adopted, nothing
written. Mutation-checked — dropping the marker rule fails three of them.
The adopt branch runs a full extra round-trip past the point every sibling
open in createCanonicalChat is probed at — registry miss, mint, title
conflict, re-consult — so it is the likeliest of them to land after the user
has clicked another bot, and it was the only one that navigated unguarded.
Adopting the winner still settles identity, which is always correct to
return; only the workspace steal is gated.
cronjob(action='run', prompt=...) context was silently dropped when the
manual run forwarded to the gateway (#96010 follow-up): POST
/api/jobs/{id}/run took no body. The forward now sends {prompt} in the
request body; the api_server validates it (length cap + strict injection
scan, same as stored prompts) and trigger_job stamps it as a transient
manual_run_prompt alongside manual_run_at. run_one_job consumes the stamp
for that single fire and mark_job_run clears it, so it never persists
into the job definition or later scheduled fires.
Ports 7c91079 onto the split modules — it landed on main in plugin.js, which
this branch deletes.
Every roster click resolved the bot's canonical Bot Chat by name and opened
it as a tab. Nothing records a tab close (this plugin keeps no closed set;
core's tile bucket only forgets), so a Bot Chat the user had closed came back
beside every newer thread on every bot switch. A click is now "go to this
bot": when the bot's workspace already holds tabs, the one the user last had
active is fronted and no chat is resolved or opened. The forever-chat opens
only when the bot has nothing open, or on the explicit ask — a new "Open Bot
Chat" row-menu item.
The claim such a click records carries only the fronted tab, so the reclaim
listener skips it and cannot resurrect the closed chat. focusExistingBotTab
is feature-detected, so an older shell keeps opening the canonical chat.
Dropped from the port: the Bots home "Open chat" button, a surface this
branch removes. The .mjs test is replaced by a real one — its two
source-reading cases become a render of the menu item in bot-row.test.tsx
and, for the reclaim guard, the claim-shape invariant the guard reads.
Stubbing usePluginI18n there also means the row's localized labels render as
text in tests instead of empty.
Keeps plugin.js and its new .mjs test deleted. main's closed-chat fix
(7c91079) landed in both; it is a real behaviour change, so the commit that
follows ports it onto the split modules rather than dropping it with the
files. Its core half — focusWorkspaceOwnerSessionTile and the
host.focusOpenWorkspaceSession verb — merged cleanly and is used as-is.
/simplify-code reuse finding: _write_marker reimplemented the
mkstemp->write->os.replace pattern that utils.atomic_write_text already
provides as the repo's shared atomic-text-write helper (and the shared
version adds fsync + cross-device/busy-file fallbacks).
Follow-up to the #95605 salvage, closing the review findings:
- _copy_alias no longer swallows OSError silently: it warns (a leftover
alias symlink is the exact #95541 crash shape) and reports failure.
- Alias staging uses mkstemp (unique names) so concurrent ensures
(update + doctor --fix) can never promote a truncated interim copy.
- The anchor marker is written LAST and atomically (write-then-rename):
it now asserts the whole layout (anchor + aliases) is complete, so a
partially-materialized alias set can never read 'active' in doctor —
the next ensure retries the install instead.
- /.hermes-runtime/python/ store marker is derived from
managed_uv._RUNTIME_DIR_NAME instead of a hardcoded string.
