In-process delegate_task children (and cron runs fired from a worker) inherit
the dispatcher worker's HERMES_KANBAN_TASK via os.environ. Three readers still
gated on the bare env var instead of is_dispatcher_owned_worker_context():
- agent/turn_finalizer.py: a child exhausting ITS iteration budget recorded
`timed_out` against the parent's task and released the parent's claim.
- tools/kanban_tools.py::inject_new_comments_from_env: a child polled operator
notes addressed to the worker, steered itself with them, and advanced the
shared per-task watermark so the worker never saw them.
- agent/title_generator.py::_kanban_task_title: a child's session was titled
after the parent's card.
Each now uses the single identity predicate. Dispatcher-owned workers are
unchanged (existing #87096 tests still pass).
Fixes#112817
format_session_db_unavailable consumes the now-pinned cause table but its own
two fallbacks (no recorded cause; network-drive gloss) still printed a bare
`hermes doctor`. Same class; one test covers both fallbacks.
Also: spell the corrupt action as plain concatenation instead of an f-string
with escaped braces, and fix the finalizer comment to state the invariant
(final_response is never rebound) rather than describe a local that no longer
exists.
hermes_state_user_copy.py is the one table feeding the CLI banner, gateway
warning and TUI/Desktop RPC errors, and its action strings were still bare
(`hermes doctor --fix`, `hermes gateway stop`, `hermes sessions recover`).
Substitute {profile_arg} once in describe_storage_failure so those surfaces
get the same pin as the turn explainer.
Also keep final_response unbound in the turn_finalizer error fallback: it
feeds the external-memory sync and the background-review gate, which must
still see an empty response on a persistence-failed turn. One test binds the
fallback (explainer stubbed empty) and the untouched final_response.
gateway/run_notifications.py::_send_session_db_warning_notifications already
computed profile_arg but left `hermes doctor` (fts_index branch) and
`hermes gateway restart` (default branch) bare; agent/turn_finalizer.py had a
bare `hermes doctor` in the error fallback used when the explainer produced
no text. Same class as the previous commit. Also reflows the explainer
strings so continuation lines break at clause boundaries.
The turn-end file-mutation verifier only sees write_file/patch receipts. It
asserted "N file(s) were NOT modified this turn" whenever a call had failed,
which is wrong when the file was in fact changed afterwards through a path
that leaves no receipt (terminal redirect, execute_code) or when the
successful retry used another spelling of the same path (relative vs
absolute, separator/case variants on Windows): the state dict was keyed on
the model's raw `path` argument, so the pop never matched.
- Header now says what the recorder knows: "N file edit(s) FAILED this turn",
and asks the user to confirm what actually landed.
- Failure entries carry the task-resolved, normcase'd on-disk identity plus a
(mtime_ns, size) snapshot; a later success clears every entry with the same
identity regardless of spelling.
- At turn end `_file_mutations_still_failed` re-stats each target and drops
entries whose file changed since the failed call, so a receipt-less
mutation no longer produces a false footer.
- `tool_executor` passes the effective task id so relative paths resolve the
way the file tools resolved them.
Kept the deliberate first-error-per-path semantics (the pinned test says why);
did not add an "unverified" bucket for receipt-less non-error results, since
the built-in tools always return a receipt on success and it would only add
noise.

An interrupted turn left `finalize_turn` with a diagnostic `final_response`
("Operation interrupted: waiting for model response") and no failure, so the
result said `completed=True` — the only producer that did; `turn_recovery`
and `codex_runtime` already return `completed=False` for an interrupt and the
gateway stream gate documents that contract. `completed` now also requires
`not interrupted`.
The API server then hard-coded the terminal status: the session chat stream
emitted `assistant.completed {completed: true, interrupted: false}` and
`run.completed` for every turn that did not raise, and `/v1/runs` booked any
non-`failed` result as `completed` — including an interrupt that did not come
through `/stop` and a turn that ran out of iteration budget. Automation that
reads the run status or the terminal event saw unfinished work as delivered,
and `partial: true` could sit next to `completed: true` in one payload.
`api_server_runs.terminal_run_status()` is now the single mapping for both
surfaces: interrupted -> `cancelled`, failed/partial/`completed=False` ->
`failed` (with `turn_exit_reason` and the fallback text as `output`),
otherwise `completed`; the terminal event is always `run.<status>` and a
late `pending_steer` rides on every terminal status instead of only on
`completed`.
CLI exit codes (`-q` quiet mode, `-z` one-shot) are deliberately unchanged
here: `hermes -z` returning 0 whenever text was produced was a stated design
choice (093f567f0d) and scripts depend on it, so that flip needs a
maintainer decision.
Fixes the gateway/producer half of #111770; slimmer redo of #111785 by
@KoNit-K (same mapping idea, one helper instead of three ladders).

Squashed integration of the user-facing message audit for this surface set.
Full per-finding receipts: /tmp/ux-audit/lanes/*-receipt.md (campaign artifacts).
Hook callbacks are gated per (hook, callback, call identity). Two hooks
on the tool-loop path fired without any identity, so concurrent terminal
calls in one turn, or overlapping turns, still collapsed onto a single
gate key and the second invocation was skipped as if a callback had hung.
transform_terminal_output now forwards the tool_call_id bound in the
approval context around dispatch (only when set); transform_llm_output
forwards the turn_id already in scope. Payloads are additive: the
dispatcher withholds unknown fields from narrow-signature callbacks.
The corruption explainer filled `{db_path}` from `_default_db_path()`, the
process default. A Desktop `serve` backend launched on the root home hosts
named-profile sessions whose SessionDB is `profiles/<name>/state.db`, so the
operator was told to inspect/repair a different profile's database. Pass the
agent's own `_session_db.db_path` from the turn finalizer; the process
default remains the fallback for agents without a bound store.
Reported in #105887.
On BASE the #95514 stream-recovery rebound final_response inline, before
the tail-closing / persist-override / micro-compaction / _persist_session
calls inside the guarded persist try-block, so a raise in any of them left
the caller with the streamed text (cleanup_errors reported the failure).
HEAD's _close_transcript_tail returned the recovered value only on normal
completion; an exception in the same block dropped it and the user-visible
answer regressed to the pre-recovery '' (then rewritten by the explainer).
Split the helper into _drop_transcript_scaffolding / _recover_final_from_stream
/ _close_transcript_tail and rebind final_response in the guarded step as soon
as it is computed, restoring BASE ordering. Adds a regression test.
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
Move the structural clone from the four call sites (auto review, codex
runtime, CLI /refine, gateway /refine) into AIAgent._spawn_background_review,
which every review path — immediate, idle-queue deferred, requeued — passes
through. Callers can no longer forget it, and the private helper is no longer
imported across hermes_cli/ and gateway/ package boundaries.
Tests now bind the real chokepoint (capturing at _spawn_background_review_now)
so they still fail if the clone is removed.
Detect same-inode cp via a generation stamp, halt FTS repair, and divert
unwritten transcripts to sessions/<id>.jsonl plus the gateway pending spool.

- Preserve streamed assistant text in Desktop UI when message.complete delivers empty text.
- Prevent destructive hydration in Desktop useMessageStream over rendered text on empty completion.
- Recover stream buffer in finalize_turn when final_response is empty on healthy turns.
- Unify in-place blank assistant repair, watermark clone resolution, non-blank concurrent winner adoption, and batch row appends into a single atomic guarded SessionDB transaction.
- Synchronize canonical committed content to live in-memory messages dicts and preserve all-or-nothing rollback semantics on persistence failure.
Independent review caught a compaction authority the gate missed:
post-turn micro-compaction (turn_finalizer -> _micro_compact) absorbs the
oldest exchanges into a rolling summary with no pre-compress checkpoint
hook in its path, and both compression.checkpoint_required and
compression.micro_compact could be enabled together — assistant evidence
could vanish into a summary the checkpoint filter later excludes, without
ever reaching the durable provider.
- agent_init: checkpoint_required forces micro-compaction off (warned),
mirroring the native-compaction suppression
- turn_finalizer: defense-in-depth guard at the call site (attribute is
plain mutable state a future path could flip on a live agent)
- behavioral regression test with a sabotage control (gate off proves the
harness reaches the call site; gate armed proves zero calls)
- docs + config example mention the suppression; stale v1 test header fixed
Review-pass follow-up on the load-time durability stamp:
- hermes_state.py: import the marker from agent.context_compressor instead
of a third synced literal (hermes_state already imports agent.* at module
level; only run_agent is circular). Old comment claimed otherwise.
- agent/turn_finalizer.py: replace the raw "_db_persisted" string at the
fill-empty-tail pop site with the shared constant (was outside the drift
guard).
- agent/conversation_compression.py: the no-op progress check now falls back
to a marker-insensitive comparison (_strip_marker_for_comparison). Loaded
rows are stamped at materialization time while compress() output is
marker-swept, so a semantically-identical no-op copy on a cold-resumed
session would previously compare unequal and take the progress branch.
Raw == still runs first so engine-returned list subclasses keep their
__eq__ semantics.
- test_marker_constant_in_sync extended to turn_finalizer + identity
assertions; new test_noop_progress_check_is_marker_insensitive
(mutation-checked: fails when the helper is neutered).
'database disk image is malformed' contains the word 'disk', so
classify_persistence_error bucketed SQLITE_CORRUPT / SQLITE_NOTADB
failures as 'disk' and the turn-completion explainer told users to
free disk space for a structurally damaged state.db (the #77386-family
misdiagnosis, reproduced in the v0.20.0 malformed-DB incident report).
- hermes_state: new 'corrupt' bucket in PERSISTENCE_ERROR_CAUSES,
matched via _DB_CORRUPTION_MARKERS BEFORE the locked/disk buckets
- run_agent: explainer text for 'corrupt' points at hermes doctor and
explicitly says freeing space will not help
- cron explainer-variant suppression picks the new variant up
automatically (it iterates PERSISTENCE_ERROR_CAUSES)
Adds a bounded fallback path in turn_finalizer.py that always records
a terminal timed_out outcome via _record_task_failure (CAS receipt path)
when the iteration budget is exhausted, regardless of whether the normal
fallback paths (interrupted/failed/anomalous exit_reason) were eligible.
Previously, a kanban worker whose budget was exhausted but whose turn was
interrupted, failed, or exited with an anomalous reason would silently
leave its task in an ambiguous lifecycle state — the dispatcher would
eventually detect it as a crashed or protocol-violation worker, but the
failure was not bounded and could take a full tick cycle to reconcile.
The CAS invariant in _end_run (WHERE ended_at IS NULL) guarantees
idempotence: if another path already closed the run, the call is a no-op.
Extracted the inline kanban-budget-exhausted recording into a shared
helper function (_record_kanban_budget_exhausted) used by both the
existing iteration_limit_fallback path and the new bounded fallback path.
Closes#87096
Refresh-loss interrupt is cooperative, so a stalled writer could still flush after another process reclaimed the conversation. Carry the holder into append_message / append_messages_batch and reject the write in the same SQLite transaction when the lease row is missing, expired, or owned by someone else.
Own the surrogate-crash class at three chokepoints instead of leaf sites:
- finalize_turn scrubs final_response once where model text leaves the
conversation loop — covers oneshot stdout (#80366), NIM/any-provider
responses (#19819), and every delivery consumer of the turn result.
- _sanitize_gateway_final_response scrubs at the gateway chat-surface
boundary — Telegram utf16_len (#55309) and Signal formatting (#55143)
can no longer see a lone surrogate; raw-text surfaces keep passthrough.
- run_conversation walks the fully-built api_kwargs with
_sanitize_structure_surrogates so tool descriptions (session_search,
#50959) and every other request-body leaf are JSON-encodable before
any provider sees them.
Regression tests pin all three chokepoints plus helper semantics.
Cherry-picked alongside #79240 (TheophilusChinomona) and #80374
(rainbowgore) whose commits precede this one with authorship preserved.
An enterprise deployment hit sustained SQLite write-lock contention on a
shared multi-gigabyte state.db (gateway + CLI processes writing
concurrently). Turns correctly failed closed with
session_persistence_failed, but the only user-facing wording claimed the
disk was full and the gateway rendered a generic failure.
The fast-fail semantics are deliberate and unchanged. This adds a pure
classifier (locked / disk / unknown) applied where the SQLite error is
still visible, threads the cause through the turn-completion explainer,
and stamps a machine-readable failure_reason
(session_persistence_failed:<cause>) plus a guaranteed non-empty error on
the result for downstream surfaces. The cron scheduler's explainer-text
suppression now matches every cause variant so refined wording cannot
leak into scheduled-job deliveries.
When the CLI streams a response token-by-token, it marks the response as
already displayed and skips re-printing after the tool loop. This means any
content appended by a transform_llm_output plugin fires after streaming — the
appended text is in the final response and stored in history, but never shown
to the user.
Fix by tracking the pre-transform response in finalize_turn() and including it
in the result dict as pre_transform_response. The CLI then checks whether the
response was transformed and, if so, prints only the appended suffix.
Previously the already_streamed branch was a no-op pass. Now it detects
post-stream plugin additions and outputs them without re-printing the streamed
body.
Phase 8 of the Hermes Agent token leak mitigation plan
(ralplan-hermes-token-leaks.md §3.9). Adds a boolean kwarg
`skip_background_review` (default False) to AIAgent.__init__ that
suppresses the end-of-turn _spawn_background_review fork.
Each background review fork instantiates a new AIAgent with its own
~15K input tokens + up to 8 LLM iterations, accumulating ~30K tokens
per event in the worst case. On cron sessions there is no
human-in-the-loop benefit from the review (no skill-creation pressure,
nobody curating MEMORY.md), so the cost is pure waste.
The end-of-turn guard now reads:
if (final_response and not interrupted
and not getattr(self, "skip_background_review", False)
and (_should_review_memory or _should_review_skills)):
skip_memory=True already disables the memory-review trigger; this
flag is the explicit single-switch off for both review paths.
Defaults to False, so behavior is unchanged for gateway/CLI callers
that omit the kwarg.
Tests: 5 new unit tests in tests/agent/test_skip_background_review.py
covering the default value, flag persistence, the gate short-circuit,
the gate fall-through, and a source-text assertion that the cron
scheduler sets the flag to True (separate commit).

The micro-compaction defrag pass (_defrag_rolling_summary) rewrites the
newest MICRO marker's content and pops _DB_PERSISTED_MARKER from the
LIVE dict in place — the same in-place pop class finalize_turn's fill
site was fixed for in #75170. Without invalidation the bounded
flush-scan cursor identity-skips the rewritten marker row and the
defragged rolling summary never reaches state.db (resume rehydrates a
stale summary).
The compressor holds no agent reference, so the pop site raises
_flush_scan_cursor_invalidated and the finalize_turn micro-compaction
block consumes it, setting agent._db_flush_scan_prefix = None.
The module-scope pop sites (context_compressor.py:175/224) operate on
fresh copies — identity-breaking by construction — and need no flag.
Follow-up to #75170 (fix-the-class sweep of _DB_PERSISTED_MARKER
in-place pops).
The bounded flush-scan in _flush_messages_to_session_db_unlocked skips
the identity-matched prefix of its previous snapshot, on the documented
assumption that no code path pops _DB_PERSISTED_MARKER from a live dict
in place. finalize_turn's pure-tool-call-tail fill is exactly that path:
it pops the marker so the filled content gets re-persisted — but the
cursor then skips the row anyway, so the delivered final response never
reaches state.db and /resume replays content="" (the #43849/#44100
class resurfacing via the perf cursor). Invalidate the cursor at the
pop site so the filled row is re-examined.
Disk-full / ENOSPC / SQLITE_FULL on first-message session persist used to be
swallowed as a debug log while prompt.submit still returned streaming, so the
send vanished with no error. Re-raise those failures, return a real RPC error,
and stamp session_persistence_failed turns with error so clients get a terminal
error frame.
Phase 2 review findings on the salvage branch:
C1 (critical): batch and micro summary markers share
COMPRESSED_SUMMARY_METADATA_KEY, and compress() never reset micro state.
After micro absorbed exchanges 1..k, a batch compaction summarizing
1..m (m>k) could fire; the next micro pass's supersede then dropped the
batch marker (whose content the stale rolling summary does NOT contain)
and archive_and_compact immediately made the loss durable. Defrag had
the same hazard: it rewrote "the newest marker" even if that was a
batch marker. Empirically confirmed with a probe (batch marker content
destroyed in one pass).
Fix, three parts:
- Micro-created markers now carry MICRO_COMPACT_MARKER_KEY; supersede
and defrag only ever touch micro-tagged markers. Rehydration in
_resolve_compact_cursor tags the marker it absorbs (containment
proof), which safely covers adopting a batch marker as the new
rolling base after a reset.
- compress() success path resets micro rolling summary/cursor state so
a stale summary can never claim cumulativeness over a batch marker.
- Regression tests for both directions plus the reset.
W4: _splice_micro_compact_result no longer strips _db_persisted stamps
from surviving messages. Micro archives in place under the SAME session
id (unlike batch's child-session rotation, #57491), so surviving stamps
are accurate; stripping them meant an archive_and_compact failure left
every previously-persisted message unstamped and the next append-only
flush re-inserted them all as duplicate active rows.
W5: finalize_turn micro gate now checks agent._persist_disabled —
persistence-isolated fork agents (background review) must not burn an
aux call per review turn, and must never archive_and_compact the
canonical session rows if their compressor ever gains a DB binding.
W1: _serialize_one_exchange now delegates to _serialize_for_summary
(was a ~70-line near-verbatim copy; one serializer, one place to fix).
S4: _find_one_exchange boundary guard rejects only assistant/tool
boundaries (the actual alternation hazard) instead of requiring user —
a stray mid-list system/injected message can no longer wedge the
cursor forever.
5 new regression tests; 38 micro/prune tests, 400 compression-suite
tests, 61 finalize/persist tests pass; ruff clean.
tests/run_agent/test_proactive_prune_loop_wiring.py builds agents with a
MagicMock compressor; getattr(mock, '_micro_compact_enabled', False)
returns a truthy auto-attribute, so the hook called _micro_compact on the
mock and spliced its (empty-iterating) return over the transcript —
wiping all messages before persist (CI slice 7/8 failure).
Gate now requires _micro_compact_enabled is True, a callable
_micro_compact, and a non-empty list result before touching messages.
Same hardening protects production plugin context engines that don't
subclass ContextCompressor.
Batch compaction pauses a session for one large summarization once the
window fills. Micro-compaction spreads that cost out: after each completed
turn, `finalize_turn` folds the single oldest un-absorbed exchange
(assistant message plus its tool results) into a rolling summary, so the
work happens in small increments during post-turn idle time instead of one
long stall.
Mechanics:
- a cursor tracks the first message not yet absorbed, recovered from the
transcript's last summary marker when in-memory state is unavailable;
- protected head and tail windows are never touched, so the system prompt
and recent turns stay verbatim;
- the absorbed span is replaced by a marker carrying the usual
`_compressed_summary` metadata, so resume, handoff and `/compress`
treat it exactly like a batch summary;
- `archive_and_compact` keeps the session DB in step, otherwise the
append-only flush would leave the original rows active and a resume
would double-load both summary and originals;
- when the rolling summary itself passes a token threshold it is
defragged: re-summarized in one shot and the cursor jumps to the tail;
- an exchange the summarizer can't handle is retried a bounded number of
times, then skipped, so one poison exchange can't stall every turn.
Keep only the newest summary marker. The rolling summary is cumulative, so
each marker already contains everything the previous ones held; leaving them
stacked near-duplicate copies of the same text, each with its own heading and
end-marker scaffolding, and the transcript grew on every turn instead of
shrinking. Measured over six turns on a 12-exchange conversation with tool
output: 4104 -> 4797 tokens before, 4104 -> 2572 after.
Off switch: `compression.micro_compact: false` (default on).

The on_turn_complete() observation hook is the engine's post-turn signal,
so it should receive the completed turn's canonical token usage when the
host has it, not a hardcoded None. Per @johnnykor82's #41918 contract: the
engine uses prompt/completion + cache_read/write/reasoning buckets to judge
how large/expensive the selected context was before the next select_context().
- conversation_loop.py: stash the most recent provider response's usage_dict
(the same canonical shape fed to update_from_response) on the agent as
_last_turn_usage; reset to None at turn start so turns that never reach a
provider response (early failure / interrupt) forward None, not a stale
prior turn's usage.
- turn_finalizer.py: forward agent._last_turn_usage instead of usage=None.
- context_engine.py: document the usage param contract on the ABC hook.
- tests: cover both ends through the real finalize_turn path — completed turn
forwards the full canonical bucket set intact; no-response turn forwards None.

Adds the post-turn observation verb as the companion to select_context():
an optional, no-op-default on_turn_complete() called once after the
assistant/tool loop finishes, with the finalized transcript snapshot. Lets
an engine ingest/index/summarize the completed turn to inform the next
select_context(). Wired via _notify_context_engine_turn_complete() from
turn_finalizer.finalize_turn(); fail-open, base no-op short-circuited so
non-implementing engines (incl. the built-in compressor) pay nothing.
This is the request-assembly + observation pair from #41918; with this
commit the PR fully subsumes #41918's two hooks (prepare_request_messages
-> select_context, on_turn_complete) rather than only the selection half.

Follow-up to the #54805 cherry-pick (skill guard rules):
- turn_context.py: snapshot_preflight_display_tokens gets a
getattr+callable guard (SimpleNamespace compressor doubles / plugin
context engines lack the ContextCompressor-only method) and the
snapshot value is type-pinned to a real int (bool excluded) before
arming the rollback — MagicMock compressors return truthy Mocks.
- turn_finalizer.py: interrupted pinned 'is True', the
_turn_received_provider_response read pinned 'is not True' (MagicMock
auto-attrs are truthy), and the compressor rollback method call gets a
getattr+callable guard. Rollback stays display-only: it never touches
_ineffective_compression_count or any durable guard, and preserves the
-1 post-compaction sentinel.
