Slim rework of despotak's modified-keypad fix in #97290. Mirror existing
non-keypad mappings for modified keypad keys, including lock-state variants,
so Alt+keypad Enter reaches the existing newline handler rather than leaking
[57414;3u into the draft. Preserve installed twin mappings before consulting
pending aliases, matching first-writer-wins registration.
Replace the source PR's keyed branch ladder with a format table and verify
parser parity plus real buffer insertion with two invariant tests. Document
keypad multiline support in English and Chinese.
Live PTY: the exact doubled leak after a real collapsed paste reproduces on
main; all 21 editor cases pass with the fix, including ordinary Enter and
legacy Alt+Enter controls. Whitespace also reproduces on main: adjacent
characters are not the root cause.

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.
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.
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.
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.
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.
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.
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.
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%.

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.
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).
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.
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.
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.
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.
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.
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.
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).
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).
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.
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).
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
feat(delegation): a failed child of a running detached fan-out is surfaced immediately, as a non-durable notice (66 min dead wave; review-found final-result loss closed)
#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.
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).
