The staleness fix (f9b1fd799) bolted two wall-clock dicts (_changed_at,
_pulled_at) onto a client that already scattered per-document state
across six parallel dicts (_files, _push_diagnostics, _pull_diagnostics,
_published, _published_version, _first_push_seen) — eight maps kept in
sync by hand.
Collapse all of it into one _DocState per path, and use the LSP document
version as the freshness token instead of clocks:
- didChange bumps doc.version; stored push/pull results carry the
version they describe (push_version from the server's echoed version,
or the current version at receipt for servers that don't echo one;
pull_version captured at request send so an in-flight pull that a
didChange races past is stale on arrival).
- fresh == tag >= version. Invalidation is implicit in the bump — no
store-clearing, no clock comparisons, no race windows.
- _has_fresh_push/_has_fresh_pull helpers dissolve into two one-line
_DocState methods; diagnostics_for(fresh_only=True) becomes a
three-liner.
Semantics are unchanged from f9b1fd799 (same tests pass, one test
updated off private internals); net -15 lines.
Slow language servers (tsserver on large projects especially) publish
diagnostics long after an edit. The client's wait/report path had three
holes that together surfaced the PREVIOUS edit's errors as if they were
current ("ghost diagnostics"), sending the agent chasing errors it had
already fixed:
1. open_file only cleared the diagnostic stores on first open — on the
didChange path (every subsequent edit) stale push/pull entries
survived.
2. wait_for_diagnostics' predicates were satisfiable by that leftover
state (`path in _published`, `path in _pull_diagnostics`), so the
"wait" often returned instantly with old data.
3. diagnostics_for merged the stale push store unconditionally, so even
a fresh clean pull got the old error merged back in.
Fix: anchor freshness on a per-file didChange timestamp.
- Pull results record their request send-time and are dropped when a
didChange raced past them; the pull store is invalidated on every
change, not just first open.
- wait_for_diagnostics now returns bool (fresh data vs timeout), only
counts pushes published at/after the change (and version >= ours when
the server echoes versions), and accepts an explicit timeout — the
user's lsp.wait_timeout config now actually controls the inner wait
budget instead of only the outer thread-join.
- diagnostics_for(fresh_only=True) excludes stores that predate the
latest change; all manager report paths use it.
- On timeout the manager returns [] ("no data") instead of stale
state, logs a WARNING via eventlog, and does NOT mark the server
broken — slow is not dead.
- seed-on-first-push no longer marks the file published, so the TS
seed push can't satisfy a waiter.
Tests: new "stale" and "slow_push" mock-server scripts model the slow
tsserver, plus client- and service-level regression tests
(tests/agent/lsp/test_stale_diagnostics.py).
test_deepseek_still_strips_signed_thinking passed model='k3' with the
DeepSeek base URL — that only held because bare 'k3' wasn't classified
as Kimi family yet. With k3 now correctly classified, the kimi-family
model-name path (deliberate: proxied endpoints preserve thinking,
#13848/#17057) keeps the blocks. Use a real DeepSeek slug for the
DeepSeek behavior, and add an explicit invariant test that Kimi-family
slugs (named and bare) keep thinking on foreign gateway hostnames.
Follow-up widening for salvaged PRs #67115, #67685, #67620:
- _PROVIDER_MODELS: add kimi-k3 atop kimi-coding / moonshot / opencode-go
curated lists (kimi-coding-cn covered by cherry-picked #67620)
- setup.py _DEFAULT_PROVIDER_MODELS: kimi-k3 for kimi-coding(-cn) + opencode-go
- model_metadata: align DEFAULT_CONTEXT_LENGTHS kimi-k3 entry to 1,048,576
(matches endpoint-scoped override, models.dev, and OpenRouter live metadata)
- anthropic_adapter: classify the bare Coding Plan slug 'k3' (and k3.x/k3-*)
as Kimi family so adaptive thinking applies on proxied endpoints
- moonshot_schema: is_moonshot_model matches bare 'k3' so tool-schema
sanitization runs on the chat-completions path
- contributor mappings for githubespresso407, datachainsystems, Punyko8
Tests: 582 passed across 11 targeted files; hermetic E2E verifies picker
order (kimi-k3 first), no dupes, and 1M context resolution.
Kimi K3 ships with a 1M-token context window (verified against
platform.kimi.ai/docs/overview) but was falling through to the generic
'kimi': 262144 catch-all. Added 'kimi-k3': 1_000_000 before the catch-all
so longest-key-first substring matching resolves K3 to 1M while older
Kimi models still hit the 256K default.
Added matching test_kimi_k3_context_1m test covering native,
vendor-prefixed (kimi/, moonshotai/), and older model fallback.
Kimi Coding serves K3 under the bare slug 'k3', but users can also
configure or select the public-facing aliases 'kimi-k3' and
'kimi-k3-cot'. The endpoint-scoped 1M context window was only keyed
on the bare 'k3' slug, so selecting 'kimi-k3' fell through to the
generic 'kimi' catch-all (262k).
Extend the guard in _endpoint_scoped_context_length to also recognize
'kimi-k3' and 'kimi-k3-cot', while keeping the endpoint check that
limits the 1M value to https://api.kimi.com/coding (legacy Moonshot
endpoints still fall back to 262k). Update the existing test to cover
all three aliases.
Fixes: context window limited to 262k when using kimi-k3 via kimi-coding.
* fix(desktop): preserve interim assistant text wiped at message.complete
When the agent emits interim text (commentary alongside tool calls, or the
attempted final answer before a verify-on-stop nudge), all UI surfaces
streamed it live but then wiped it at message.complete — keeping only the
final response. The user saw text appear during inference, then disappear.
This is the complete fix across all three layers: agent core, gateway
transport, and all UI surfaces (desktop + Ink TUI).
The verify-on-stop and pre_verify paths flagged the assistant's attempted
final answer as _verification_stop_synthetic, suppressing it from both
state.db and the UI. The user only saw the terse post-verification reply.
Now the assistant response is real content: it's persisted to state.db and
emitted as an interim message via _emit_interim_assistant_message(force_display=True)
before the verification loop runs. Only the synthetic nudge messages keep
the synthetic flags. The turn finalizer drops nudges from live history and
compares content (not just role) to avoid duplicating a published candidate.
Message sequence repair collapses verification candidates in the
consecutive-assistant merge.
Wire agent.interim_assistant_callback both at construction (_agent_cbs())
and per-turn (defense-in-depth), emitting a new message.interim event with
{text, already_streamed}. Gated on display.interim_assistant_messages
(default true). Cleared in the finally block so a stale closure can't
fire on a later turn.
Add message.interim to the GatewayEventName union (apps/shared) and a
typed payload to the TUI's GatewayEvent discriminated union.
The TUI already had the segment-anchoring machinery (flushStreamingSegment +
finalTail) but had no handler for message.interim. Added recordInterimMessage
+ interimBoundaryIndex to seal segments mid-turn, and updated
recordMessageComplete to only dedupe segments after the interim boundary.
Replaced the fragile sealed-set approach with a proper interimBoundaryPending
state flag on ClientSessionState. finalizeInterimAssistantMessage finalizes
the streaming bubble in place (or creates a standalone one), rotates the
stream ID so next deltas create a new bubble, and sets the flag. When the
final text equals an already-sealed interim, they stay as distinct messages.
Extracted mergeFinalAssistantText() as a pure function in chat-messages.ts,
used by both completeAssistantMessage and finalizeInterimAssistantMessage.
Split the bidirectional dedup predicate: reasoning is a restatement only when
the final FULLY covers it. A short final ("Done.") no longer swallows a
longer reasoning block that merely starts with it.
Honor display.interim_assistant_messages (default true) across all layers:
the tui_gateway gates the callback, the desktop wires it to a nanostores
atom via use-hermes-config. Updated hermes_cli/config.py and
cli-config.yaml.example comments to document the Desktop behavior.
_split_segment_tokens now accepts posix=False and _find_ad_hoc_match tries
both posix modes so ad-hoc verification scripts with Windows backslash
paths are matched correctly. (response_previewed forwarding from #53553
is not included — our emit-interim + persist approach makes it unnecessary
since the attempted answer is now surfaced before the verification loop.)
- tsc: clean (desktop + TUI + shared)
- vitest desktop: 73/73 pass (7 interim-sealing + 5 mergeFinalAssistantText + 4 config atom)
- vitest TUI: 83/83 pass (4 new message.interim tests)
- python: 390 tests pass (340 tui_gateway + 33 verification/finalizer + 6 config gating + 3 evidence + 8 continuation budget)

* fix: prefix-match interim streamed content to avoid benign duplicate bubbles
_interim_content_was_streamed used exact equality (streamed == visible_content),
so a final response that was the streamed text plus a trailing delta — or a
partial stream before the verify nudge fired — failed the match and left
_response_was_previewed false. The turn then showed two bubbles (interim +
identical final) instead of settling the interim in place.
Relax to a prefix check (visible_content.startswith(streamed)) in both the
core match and the desktop's settle-in-place gate. The TUI already used
prefix matching via finalTail. The reverse direction (streamed longer than
final) is intentionally not matched — that could suppress a needed resend
in the gateway path where already_streamed=True calls on_segment_break().
* test(desktop): add partial-stream-then-nudge dedup edge case
Third edge case for the interim-sealing dedup: model streams part of its
answer via message.delta, verify nudge fires, interim seals the streamed
prefix, then the final response is the same text plus a trailing delta.
Asserts one bubble (not two) containing the full final text.
Acceptance protocol #2 — covers all three dedup edges:
1. interim == final (existing)
2. interim = strict prefix of final (existing)
3. partial-stream-then-nudge (this commit)

- The #44861 stale-cache guard invalidated any cached value that differed
from the static table, which would have discarded legitimate
probe-derived windows larger than the table. Treat the table as a
FLOOR: only drop under-reporting cache entries.
- Update probe test fixtures that predated the 4.6+ 1M table flip
(opus-4-6 fallback expectations 200K -> 1M).
Bedrock models resolved their context window from a hardcoded table
(BEDROCK_CONTEXT_LENGTHS) keyed by longest-substring match. AWS ships
new model versions faster than the table tracks, so a new model like
claude-opus-4-8 (1M-token window) silently matched the older
"anthropic.claude-opus-4" entry and got capped at 200K — wasting 80%
of the available context.
Bedrock exposes the real window nowhere in metadata: get-foundation-model
omits it, Converse usage metrics omit it, CountTokens is unsupported on
several models. The only authoritative source is the ValidationException
raised when a prompt exceeds the window:
"prompt is too long: 1300032 tokens > 1000000 maximum"
Length validation runs before inference, so an oversized request is
rejected immediately and cheaply (no tokens generated, no input
processed). This adds probe_bedrock_context_length(): pad a request just
past a tier, parse the reported maximum, return it. get_bedrock_context_length()
now probes first and falls back to the static table only when the probe
can't run (missing creds, network error, unparseable error). The static
table stays as a safety net.
get_model_context_length() caches the probe result per model+region, so
the network cost is paid once, not every turn. probe=False / empty region
disables probing for offline/display paths — backward compatible with the
single-arg callers.
Verified E2E against live Bedrock (eu-central-1): claude-opus-4-8 resolves
to 1000000. Unit tests cover error parsing, unparseable errors, missing
client, probe-beats-table, and table fallback.
BEDROCK_CONTEXT_LENGTHS was missing entries for current 1M-context Claude
models, and the resolution path in get_model_context_length() short-circuits
to that table (step 1b) before DEFAULT_CONTEXT_LENGTHS is ever consulted, so
the catalog's correct values could never apply on Bedrock:
- claude-fable-5 (no entry at all) fell through to
BEDROCK_DEFAULT_CONTEXT_LENGTH and reported 128K for a 1M model.
- opus-4-7 / opus-4-8 substring-matched the generic 'anthropic.claude-opus-4'
key and reported 200K.
- opus-4-6 / sonnet-4-6 had explicit 200K entries predating their 1M windows.
The practical symptom: the agent compresses context prematurely (at ~128K or
~200K of a 1M window) on every Bedrock-hosted current Claude model.
Fixing the table alone is not enough for existing installs: a previously
persisted 128K/200K value in the context-length cache wins at step 1 and
masks the corrected table forever. Step 1 now reconciles Bedrock-context
cache hits against the static table (the table is authoritative for Bedrock
— there is no live probe to reconcile against), invalidating stale entries
so existing users converge to the right window without manual cache surgery.
Tests cover the new table entries (incl. inference-profile and versioned ID
forms), the 128K-default regression for Fable, the stale-cache invalidation
path, and that pre-4.6 models keep their 200K entries.
_normalize_bedrock_model_name stripped ("us.", "global.", "eu.", "ap.",
"jp.") before the pricing lookup, but AWS Bedrock's Asia-Pacific
cross-region inference profiles are prefixed "apac." (and Australia
"au."), not "ap.". A bare "ap." never matches an "apac.*" id
(str.startswith stops at the 'a' where "ap." expects '.'), so
"apac.anthropic.claude-*" and "au.anthropic.claude-*" fell through with
the prefix intact, missed the bare "anthropic.claude-*" pricing key, and
every Asia-Pacific / Australia Bedrock session priced as "unknown" — no
cost estimate or tracking for two whole geographies, while us./eu./global.
worked.
Add "apac." and "au." to the strip list (mirrors the same fix landing in
bedrock_adapter.is_anthropic_bedrock_model via #46297, which covers the
prompt-caching capability gate but not this duplicated cost-lookup copy).
Extends the existing cross-region pricing test to cover apac./au.; without
the fix it fails with scoped == None for "apac.".
is_anthropic_bedrock_model() strips a regional prefix before checking for
"anthropic.claude" to route Claude through the AnthropicBedrock SDK path
(prompt caching, thinking budgets) instead of the Converse path. The prefix
list was missing "au." and "ap." does not match "apac.", so AU/APAC Claude
inference profiles silently lost prompt caching. Add "apac." and "au.".

Addresses hermes-sweeper review on PR #66167:
1. _convert_content_to_converse() still emitted {"text": part} directly
for plain-string items inside a content list (as opposed to
{"type": "text"} dicts), bypassing _safe_text() entirely. A
whitespace-only string item (e.g. [" "]) could still reach Bedrock
as a blank block. Now routed through _safe_text().
2. tests/agent/test_bedrock_adapter.py::TestEmptyTextBlockFix asserted
the pre-fix behavior (whitespace -> literal space " "), contradicting
the new _safe_text()/_EMPTY_TEXT_PLACEHOLDER behavior added in
4618095a. Updated assertions to expect the non-whitespace placeholder,
plus added a regression test for the list-string-item case above.
Bedrock Converse rejects text content blocks that are empty OR
whitespace-only (ValidationException: "text content blocks must
contain non-whitespace text"). The prior fix attempt substituted a
single space (" ") for missing content -- but a lone space IS
whitespace, so it was rejected by the exact same validation rule it
was meant to satisfy. This caused a deterministic, unrecoverable
retry-loop failure once any blank/whitespace assistant, tool, or user
turn entered history (most commonly via context-compaction rewriting
a turn to a blank string).
Adds _safe_text()/_EMPTY_TEXT_PLACEHOLDER ("(empty)") and applies it
everywhere a blank text block could reach the wire: user/assistant
content conversion, tool results, the assistant-empty-turn fallback,
and the first/last-message user-alternation padding. System-prompt
blocks are the one exception: blank parts are dropped entirely rather
than placeholder-filled, since a system prompt block should never
carry meaningless placeholder text.
Adds tests/agent/test_bedrock_empty_text_blocks.py (11 tests, was
already present uncommitted -- codifies the exact failing history
from issue #9486 and asserts no blank block ever reaches Bedrock).
Verified against the actual failed request dump from this session
(27-message payload) -- replaying it through the fixed converter now
produces zero blank/whitespace-only blocks.
The Bedrock static context table only had entries up to the 4-6
generation and capped all Claude models at 200K. Newer model IDs
(opus/sonnet 4-7, 4-8) silently inherited 200K via the generic
"anthropic.claude-opus-4" / "...-sonnet-4" substring fallback,
contradicting the native Anthropic table in model_metadata.py which
already maps these to 1M.
Map opus/sonnet 4-6/4-7/4-8 to 1_000_000 on Bedrock. Haiku 4.5,
sonnet 4.5, legacy Claude 4 and 3.x stay at 200K (no 1M window).
Add opus-4-8 coverage and haiku/sonnet-4-5 200K guards.
Update TestBedrockContextLength to assert the corrected values from
BEDROCK_CONTEXT_LENGTHS:
- test_claude_opus_4_6: 200_000 -> 1_000_000 (1M GA for Opus 4.6)
- test_claude_sonnet_versioned: 200_000 -> 1_000_000 (1M GA for Sonnet 4.6)
- test_inference_profile_resolves: 200_000 -> 1_000_000
(us.anthropic.claude-sonnet-4-6 resolves to Sonnet 4.6's 1M value)
Also adds three new test cases that document Anthropic's published
context windows explicitly and guard against future regressions:
- test_claude_opus_4_7: asserts 1_000_000 and cites the models overview
- test_claude_sonnet_4_5_is_200k: asserts 200_000 and cites the
April 30, 2026 release note retiring the 1M beta for Sonnet 4.5
- test_claude_haiku_4_5_is_200k: asserts 200_000 for Haiku 4.5
All 178 tests in test_bedrock_adapter.py pass after the change.
Adds current-gen Claude Opus pricing rows on Bedrock keyed to Anthropic's
published list price, which commercial Bedrock on-demand mirrors. Also
corrects the existing Opus 4.6 row: it carried Claude-3-era Opus pricing
($15/$75); Opus 4.5+ list at $5/$25 with cache write 1.25x / read 0.1x.
The AWS Price List API had not published these SKUs machine-readably as
of 2026-07, so these are commercial-list snapshots pending an
authoritative machine source.
Reapplied from PR #62327 (commit authored under a placeholder identity,
so cherry-pick was not usable; sonnet-5 row from that PR already landed
via #67932).

_find_tail_cut_by_tokens aligns cut_idx away from tool-call/result
boundaries (_align_boundary_backward), and both tail anchors re-align after
moving it. The final statement then raised the result to head_end + 1 so
compression always claims at least one message — without that floor the
caller's compress_start >= compress_end guard turns the pass into a no-op
that re-runs forever.
That raise discarded the alignment. When the floor landed inside a tool
group, the parent assistant(tool_calls) fell in the summarised region while
its tool results started the tail, and _sanitize_tool_pairs dropped those
orphans outright — so the tool output was neither summarised nor kept. It
vanished. That is exactly the silent loss _align_boundary_backward's own
docstring says the alignment exists to prevent.
Two back-to-back tool calls are enough to trigger it on default settings
(protect_first_n=3):
system, assistant(call_1), tool, tool, assistant(call_2), tool
aligned cut = 4 (keeps call_2's group together)
returned cut = 5 (floor overrode it)
summarised region = [assistant(call_2)]
tail = [tool(call_2)] -> orphan -> dropped
Sweeping every well-formed block layout up to length 6 (21840 transcripts),
5623 of them — 26% — split a call/result pair this way.
Re-align FORWARD after applying the floor. Forward, never backward: pulling
back would hand return the message the floor just claimed and reopen the
no-op loop. Sliding forward instead moves the cut past the end of the group,
so the whole call/result pair is summarised together and nothing is
orphaned. The same sweep reports 0 violations after the change, and the
progress guarantee is pinned by its own test.
grok-4.5 is xAI's newest release (their versioning is non-monotonic:
4.5 > 4.20) and is the model xAI's own docs use for the server-side
x_search tool. Users who explicitly pinned x_search.model keep their
choice; everyone else picks up the new default via the config
deep-merge — no _config_version bump needed.

- hermes_cli/config.py: DEFAULT_CONFIG x_search.model + comment
- agent/reasoning_timeouts.py: 300s stale-timeout floor entry for

- docs: x-search.md en + zh-Hans (config sample + troubleshooting)
- tests: default-model assertion + timeout-floor positive case
Kimi's Anthropic-compatible endpoints (api.moonshot.cn/anthropic,
api.kimi.com/coding) implement the adaptive thinking contract — they
accept thinking.type=adaptive + output_config.effort (all of low,
medium, high, xhigh, max verified live) and return thinking blocks, and
the replay-validation 400s that originally motivated dropping the
parameter (#13848) no longer occur.
_supports_adaptive_thinking() now returns True for Kimi-family models,
so they get thinking={type: adaptive, display: summarized} +
output_config.effort via ADAPTIVE_EFFORT_MAP instead of nothing, and
the blanket drop of the thinking parameter for Kimi-family endpoints is
removed. MiniMax and other non-adaptive third parties keep the manual
budget_tokens path; Claude behavior is unchanged.
The per-message ephemeral context prompt re-renders every turn, and
any byte change (Discord auto-thread rename, reset notes, voice
channel state) both breaks the provider prompt-cache prefix at the
head of every request and changes the gateway agent-cache signature,
forcing a full agent rebuild per message. Pin the rendered block per
session keyed by a hash of exactly the fields it renders, so only a
real input change (rename, topic edit, /sethome, redact_pii flip)
re-renders; deliver one-shot per-turn facts (auto-reset note,
first-contact intro, voice-channel changes) on the current user
message via the api_content sidecar instead of the system prompt; sort
get_connected_platforms for byte-stable ordering.
_manage_thinking_signatures treated every Kimi-family endpoint with the
#13848-era contract: strip signed Anthropic thinking blocks from replayed
history, assuming the upstream cannot validate Anthropic signatures.
Live probing shows that contract is outdated for the whole Kimi family:
- Kimi For Coding (api.kimi.com/coding) issues AND validates its own
thinking signatures (K3+): both verbatim and content-mutated signed
blocks replay with HTTP 200;
- Moonshot's Anthropic surface (api.moonshot.cn/anthropic) accepts signed
blocks the same way (200 on both verbatim and mutated);
- every other harness that replays signed blocks to KFC (Claude Code, pi,
Kilo Code) round-trips fine.
Stripping signed blocks there silently discarded the model's prior
chain-of-thought in multi-turn conversations — e.g. a two-turn recall
probe loses the reasoning between turns while the text answer survives
(agent.log: turn-2 input ≈ turn-1 input + a few dozen tokens instead of
+thinking). With this change, the same probe recalls the exact hidden
values from turn-1 thinking (+230 tokens on turn 2).
So: on _is_kimi_family_endpoint, keep signed and unsigned thinking blocks
unchanged on replay — one uniform rule for the whole Kimi family, no
/coding-vs-Moonshot split. DeepSeek keeps the #16748 contract (strip
signed, preserve unsigned). Third-party and direct-Anthropic behavior is
untouched.
Add tests/agent/test_anthropic_kimi_signed_thinking_replay.py pinning the
unified behavior (Kimi /coding + Moonshot keep signed and unsigned) and
the unchanged neighbors (DeepSeek strips, direct Anthropic keeps).
Background-review forks share the live parent's session_id for prompt-cache
warmth but are _persist_disabled — they can never write to the transcript.
Without this, every review fork on an active session would (a) trip a false
cross-agent overlap warning against the parent's real turn, sending the
#64934 route investigation the wrong way, and (b) pop the parent's in-flight
slot at its own persist, making a real overlap right after a review go
unreported. Both legs now skip persist-disabled agents symmetrically.
+2 tests.
note_turn_start kept its in-flight marker on the agent object, but the
gateway caches agents per routing key (_agent_cache) while transcripts
are owned by session_id — and switch_session (/resume from a second
surface, CLI-continuity rebinding, async-delegation pinning,
topic-binding tip-walks) maps multiple routing keys onto one session_id
without any cross-key check. Two keys mapped to one session run
concurrent turns on two different agent objects, so the per-agent
tripwire could never fire for exactly the dispatch route #64934 is
waiting to identify.
Add a module-level session_id-keyed in-flight registry alongside the
per-agent marker. Same philosophy as the original tripwire: log-only,
takes ownership on overlap, under-reports rather than double-reports
(a same-agent overlap warns once, not twice). The persist-time clear
pops the session id stamped at turn start, so a mid-turn compression
rotation of agent.session_id cannot strand the slot.
The ineffective-compression counter is not durable; when it is the sole
reason the gate is blocked there is nothing in the DB that could unblock
it, so re-reading the guard rows on every gate check for the rest of the
session is pure waste. Guard test pins the no-DB-touch behavior.
Follow-up on the salvaged #64511 commit:
- _automatic_compression_blocked() now refreshes durable guard state
(cooldown + fallback streak) when — and only when — the in-memory
snapshot says blocked, then re-evaluates. The should_compress()
pre-gates (preflight/turn paths) consult this before ever reaching
compress_context, and a stale fallback streak has no expiry timer, so
without a gate-level refresh a cleared durable row could never unblock
a prebound agent. The unblocked hot path pays no DB reads.
- A refresh that finds no durable cooldown row no longer clears a live
local cooldown whose DB persist FAILED (_cooldown_persist_failed):
an empty row is not evidence another agent cleared it, and honouring
it would reopen the #11529 thrash window. A successful durable
round-trip (record or read) makes the DB authoritative again.
- Guard tests for both directions (red on the pre-fix code), including
a hot-path test asserting the unblocked gate never touches the DB.
Follow-up hardening on top of the salvaged #66637 commits:
- _insert_real_user_anchor could place the restored human turn directly
next to user-role scaffolding (index-0 insert before a leading synthetic
user turn, or a scaffolding-only transcript), breaking the strict
alternation contract (#55677). Restoration now merges into trailing
scaffolding (anchor text leads, synthetic flags cleared) and appends
after a user-role compaction summary instead of inserting adjacent.
- _is_real_user_message now also rejects user-role compaction summaries
(the compressor pins the summary to role=user when the tail opens with
an assistant turn), so a summary can no longer satisfy the human-anchor
check and skip restoration.
- _latest_user_task_snapshot reuses the same real-user predicate, so the
deterministic task snapshot can no longer anchor on todo snapshots,
truncation notices, or background-process reports.
- The Historical Task Snapshot rewrite keeps the section terminated with
a blank line; the previous replacement consumed the boundary newlines,
gluing the next '## ' heading mid-line and deleting all later sections
on the next iterative compaction.
- Drop _length_continuation_synthetic (no producer anywhere).
- AUTHOR_MAP entry for enzo-adami.
The first LLM call of every gateway turn gets ~0% provider prompt-cache
hit rate (in-turn calls: 97-99%) because the bytes sent for a turn's
user message are not the bytes replayed next turn: memory-prefetch and
pre_llm_call context are injected into the API copy only, the #48677
persist override writes cleaned content to the DB row, and
get_messages_as_conversation sanitize/strips user and assistant content
on load. Any of these diverges the request prefix at that message and
re-prefills everything after it — measured 27.9s for the first call vs
2.4-5.8s cached at a median ~156k-token context.
Persist what you send: a nullable messages.api_content column stores the
exact content string sent to the API when it differs from the clean
stored content, and replay substitutes it verbatim (no sanitize, no
strip). The injection composition lives in one helper
(turn_context.compose_user_api_content); the turn prologue stamps its
output onto the live user message, the api_messages build sends the
stamped bytes, and every outgoing copy pops the field so it never
reaches a provider. The crash-resilience user-turn persist moves after
prefetch/pre_llm_call so the user row is written once with its final
sidecar; _ensure_db_session stays before preflight compression (session
rotation needs the parent row under PRAGMA foreign_keys=ON). The
current-turn index trackers are re-anchored after compaction rebuilds
the message list, in-place preflight compaction backfills the stamp onto
the already-inserted row, and gateway replay forwards the sidecar only
when the replay pipeline did not rewrite the content. Rewrite paths that
would leave stale bytes (historical image strip, merge-summary-into-
tail, consecutive-user repair merge, stale-confirmation redaction) drop
the sidecar; the chat-completions transport and the max-iterations
summary path strip it defensively. codex_app_server and MoA turns are
excluded from stamping because their wire bytes differ from the
composition. A missing or dropped sidecar degrades to today's behavior
(one cache-boundary miss), never to wrong content.
Extract the inline pure-tool-call tail check to a named helper using
flatten_message_text (canonical content extraction). Fix a SQLite
durability regression: the incremental tool-call persist
(conversation_loop.py:4990) stamps _DB_PERSISTED_MARKER on the assistant
row, so the next _persist_session flush skips it — the filled content
reaches the in-memory transcript but NOT the durable store, and /resume
reloads content="". Pop the marker so the next flush re-writes the row.
Tests pass, ruff clean.
`finalize_turn` guarantees the invariant "delivered final_response =>
assistant row in transcript" (#43849 / #44100) for recovery paths that
return a response without appending a closing assistant message. It
enforces it by checking only the tail's ROLE:
if _tail_role != "assistant":
messages.append({"role": "assistant", "content": final_response})
A tail that is a *pure tool-call turn* — `assistant(tool_calls=[...])`
with no text of its own — satisfies that check while carrying none of the
delivered answer. The append is skipped and the response is never
persisted, so the durable transcript ends at an assistant row the user
never saw as the reply. On the next turn the model replays the user
backlog and re-answers it: exactly the symptom the block was added to
prevent, just reached through a different tail shape.
Observed with the real finalizer: with messages ending
`user -> assistant(content="", tool_calls=[t1])` and
`final_response="Here is your answer."`, the persisted transcript keeps
`content=""` and the answer is absent.
Fill that row's empty content instead of appending. This keeps the
invariant without disturbing the tool-call structure and without creating
an assistant->assistant pair. A tail tool-call row that already carries
model text is left untouched, so no model output is ever overwritten.
Adds regression tests for both: the empty tool-call tail is filled, and a
tool-call tail with existing text is not clobbered.
Direct-Anthropic requests used a single shared _anthropic_client, and the
stale/interrupt watchdog closed + rebuilt it from the poll (stranger) thread
at four sites (non-streaming stale/interrupt, streaming stale/interrupt).
Closing a client whose TLS socket a worker thread was still reading released
the FD from a stranger thread; the kernel recycled it under a live SSL BIO,
which then wrote a 24-byte TLS record into an unrelated SQLite header
(cron/executions.db), bricking every cron on the profile. Same shape as the
OpenAI-only #29507 fix, but the Anthropic path never got the owner-thread
contract.
Extend the #29507 ownership contract to Anthropic: build a per-request client
(_create_request_anthropic_client), register it with the request-client
holder tagged by kind, and route _close_request_client_once by kind — a
stranger thread only shuts the request client's sockets down
(_abort_request_anthropic_client), while the owning worker performs the SDK
close (_close_request_anthropic_client). The shared _anthropic_client is now
never closed from inside a request (streaming or non-streaming), including the
worker retry-cleanup sites, since each attempt builds a fresh request client.
The #28161 no-hang guarantee is preserved: the poll-thread socket abort
unblocks the worker immediately.
Salvages the approach from #51688 (@raymondyan-zhijie), reimplemented onto
current main (non-streaming dispatch was refactored into
_dispatch_nonstreaming_api_request; streaming grew _cancel_current_stream_attempt
and worker retry-cleanup sites). Tests updated to the request-local mechanism
(incl. replacing a banned source-reading test with a behavior test) plus new
regression coverage proving the watchdog aborts the request client and never
touches the shared client.

Builds on the salvaged typing_status_text plumbing (PR #62007): instead
of a static 'is thinking...', Slack's assistant status line now updates
live as the agent works — 'is running pytest tests/…', 'is reading
docs/api.md…' — and reverts to the static text between tool calls.
Mechanics:
- agent/display.py: build_status_phrase() derives a <=49-char present-
tense phrase from the existing _TOOL_VERBS table (+ 'is using <name>'
for plugin/MCP tools; None for _thinking).
- base adapter: supports_status_text capability flag + set_status_text()
per-chat store, cleared when the typing loop winds down.
- Slack adapter: send_typing() renders the live phrase when set, falling
back to typing_status_text then 'is thinking...'.
- gateway/run.py: progress_callback stashes the phrase on tool.started
and clears on tool.completed. Rendering rides the existing
_keep_typing refresh cadence — zero additional Slack API calls, no
rate-limit exposure. Works with tool_progress: off (Slack default);
the callback is now armed whenever the adapter supports status text.
- display.live_status config (full|verb|off, default full): 'verb' hides
argument previews for shared/customer-facing channels.
Also fixes a latent crash in the cherry-picked from_dict: malformed
non-dict 'extra' sections broke typing_status_text resolution (uses the
already-coerced extra dict).
Design notes: status text is a side-effect display channel only — never
enters the transcript, no prompt-cache impact. Lifecycle guarantees from
the stuck-status fix family are preserved (per-thread tracking,
clear-on-finish via existing stop_typing paths). Related: #45109
(closed; same direction via lifecycle states), #59010/#51363 (native
task cards — complementary, larger scope).
Re-applied against v0.18.2. Upstream now covers the OpenAI-path stall watchdog
(cross-turn give-up breaker #58962) and the tool-batch deadline, so those are
dropped. Two gaps remain:
- Bedrock streaming had NO liveness watchdog and was excluded from the #58962
breaker (it returns before _check_stale_giveup). Add an on_event hook to
stream_converse_with_callbacks (fires per yielded event = true wire-level
liveness), drive a stale timer from it, and wire Bedrock INTO the existing
breaker: entry _check_stale_giveup, _bump_stale_streak on stall, raise to end
the call (invalidate_runtime_client can't abort the in-flight botocore stream,
so the streak escalates across turns like the OpenAI path), and reset the
streak on success.
- local providers still got float('inf') stale timeout (watchdog disabled) — give
a finite ceiling (HERMES_LOCAL_STREAM_STALE_TIMEOUT, default 900s).
- tests: on_event per-event + swallow; Bedrock stall bumps streak + aborts;
pre-elevated streak aborts at entry; success resets streak.

Follow-up to the salvaged #66609 (4 primary readers) and #41604 (context
files): two more jobs.json readers rejected a BOM'd file —
- hermes_cli/backup.py _count_cron_jobs: a BOM made the count None,
silently disabling the post-update cron-loss auto-restore safety net
- agent/curator_backup.py _backup_cron_jobs_into: BOM broke the job
count (spurious parse_warning) and propagated the BOM into snapshots
Both now read utf-8-sig; curator snapshots are written BOM-free so
rollback restores a file load_jobs can read. AUTHOR_MAP entry added
for deacon-botdoctor.
Tests: BOM'd-live-file auto-restore + BOM'd snapshot count/BOM-free copy.
