Consolidates #4162 + #3944. Aux path: skip the reasoning-disable inject for
routes that 400 on it via _route_rejects_reasoning_extra — hostname-matched
OpenAI / Azure OpenAI / Azure AI Foundry (+ provider aliases openai*/azure*/
azure-foundry/azure-ai*) and OpenRouter Anthropic mandatory-reasoning; keep it
for local/OpenRouter-non-anthropic/other reasoning routes (#4161). Agent path:
rely on the existing agent.reasoning_config={enabled:False} + _build_api_kwargs()
(route-correct per provider profile) rather than re-injecting a generic disable
on top of it; only MiniMax reasoning_split is added (unchanged from master).

Resolve custom provider API keys from the matched config snapshot and pass them through session hydration plus streaming fallback context-length probes. This prevents authenticated /v1/models endpoints from falling back to the default 256K window and clobbering larger persisted session metadata.
Codex caught a regression: the contributor's _runtime_preferred_base_url preferred
the runtime base_url for ALL non-custom providers, which would clobber an explicit
providers.<id>.base_url override pointing at a different host/port (LM Studio at a
LAN IP, an OpenRouter mirror). Now only prefer the runtime URL when it's the SAME
scheme+host+port as the configured one (the #3895 /v1-dedup case is path-only on
the same host); a genuinely different configured endpoint wins. Added
_same_base_url_endpoint() + 2 regression tests (different-endpoint preserved,
same-endpoint normalization).
Extract _build_partial_message() shared by cancel_stream() and the new
_snapshot_and_append_partial_on_error(); the two provider/exception error paths
in _run_agent_streaming now snapshot accumulated text/reasoning/tool_calls under
STREAMS_LOCK and append a _partial assistant message instead of discarding it.
Closes#3929.

* fix(session): retire stale truncation watermark on new committed turn (#3831)
retry_last / undo_last / the Edit-truncate handler set truncation_watermark
to suppress the *replaced* tail from the append-only state.db merge.
Session.save() deliberately never auto-clears it (#2914), but nothing retired
it when the user then sent a genuinely NEW turn either — so it froze at the old
edit boundary. A frozen watermark then dropped post-watermark state.db rows
whenever the sidecar was later reconstructed empty (recovery/reconcile),
permanently losing the turns sent after the edit (state.db still had them).
Retire a POSITIVE watermark to None once the new user turn is COMMITTED to
session.messages — at the success-merge (3 sites), eager-checkpoint, error/
recovery materialization, and cold-load repair commit points. Not at chat-start:
in deferred mode the new row isn't in messages yet, so a merge in that window
would resurrect the replaced tail (the max-sidecar guard hasn't risen past the
old boundary). Once committed, max_sidecar_timestamp rises past the replaced
tail and the merge suppresses it without the watermark, so retiring is safe.
Cleared to None, never 0.0 — 0.0 is the truncate-to-empty sentinel (#2914) that
must keep blocking all state replay, so the clear is falsy-gated.
Closes#3831
* chore(changelog): clarify watermark-retirement timing to commit-time
Greptile review noted the original phrase "retires the watermark at the
start of a new user turn" was timing-imprecise. The retirement actually
fires when the new turn is durably committed to session.messages —
at the agent-result merge, the eager user-message checkpoint, or the
cold-load recovery commit. Reword for accuracy; semantics unchanged.

* test(#3831): add regression tests for the two inline watermark-clear paths (greptile P2)
Cover the error/cancel materialization path (_materialize_pending_user_turn_before_error)
and the eager first-turn checkpoint path (_checkpoint_user_message_for_eager_session_save),
which inline the falsy-gated watermark clear instead of calling the tested helper.
The error path is precisely the #3831 failure mode (recovery/reconcile after a
crash), so a dedicated regression test closes that gap. Both assert a positive
watermark clears to None while the 0.0 truncate-to-empty sentinel (#2914) is
preserved.

* fix(bg_task): unsubscribe SessionChannel on header-write failure (Codex deep-review catch) + regression test
* test: realign on-subscribe-recovery anchor to subscribe_to_session_channel after leak fix
* CHANGELOG: bg_task trio as v0.51.340 LD (HELD pending independent review)
* bg_task trio: apply 3 independent-review (greptile) fixes
1. start_session_turn now threads the session PROFILE model defaults
(_read_profile_model_config) into the wakeup model-resolve, so a brand-new
session with an empty model falls back to the profile default not global
DEFAULT_MODEL. Updated the white-box spy test signature accordingly.
2. /api/session/stream omits the Connection header (HTTP/1.1 keep-alive
default) to match the #3103 long-lived-SSE pattern.
3. Reaper now prunes _LAST_EMIT_TS for collected sessions so the coalesce
timestamp map can't grow one permanent entry per session forever.
nesquena APPROVED the PR; these are the 3 non-blocking greptile suggestions.
* test: realign _start_session_turn adapter stub lambda to new profile-defaults signature
* fix(streaming): make per-token inline-thinking extraction linear (#3633 follow-up)
Codex post-merge perf catch on #3633: _parseStreamState() and
syncInflightAssistantMessage() call _extractInlineThinkingFromContent on the
FULL accumulated assistantText on EVERY streamed token. The #3633 rewrite made
that a full char-by-char walk, so cost was O(n^2) over a stream — a Node harness
measured ~88s (no-tag) / ~103s (leading <think> block) for 2000x100-char tokens,
which would freeze the main thread on long reasoning-model responses.
Two fixes (Python api/streaming.py + JS static/messages.js twin, line-for-line parity):
1. Fast path: if the text contains no complete thinking opener AND (when
streaming) its tail is not a prefix of an opener, return unchanged without the
char walk — two cheap substring scans. Handles the common no-tag case.
2. Bulk-skip plain trailing content: track the next complete opener via
str.find/indexOf (_next_inline_thinking_opener / _nextThinkingOpener); once no
opener remains ahead, append the remainder and stop instead of walking it
(streaming still suppresses a trailing partial-opener prefix). Handles the
leading-block-then-long-answer case.
Result: ~88s/103s → ~0.5s/0.9s (Python), ~0.18s/0.21s (JS). All behavioral cases
(persist + streaming, code-awareness, position-aware unclosed, leading whitespace)
verified unchanged in both twins. Added a per-token streaming perf regression test
and wired _nextThinkingOpener into the node driver harness.
Co-authored-by: rodboev <rodboev@users.noreply.github.com>
* fix(streaming): perf bulk-skip must respect code context for partial-opener tails
Codex catch on the perf fix: the no-complete-opener bulk-skip suppressed a
trailing partial opener (e.g. '<thi') unconditionally during streaming, but a
partial opener INSIDE inline-backtick / fenced / indented code must stay visible
(master parity). Now, when streaming and the tail is a partial opener, fall
through to the code-aware char walk (bounded — a partial tail is a transient
single token) instead of bulk-skipping; only a PLAIN-text partial opener is
suppressed as a forming block. Added _text_tail_is_partial_opener /
_textTailIsPartialOpener (Python + JS parity) + regression tests for the
inside-code vs plain partial-tail cases.

* fix(streaming): normalize inline thinking extraction across live and persisted turns (#3599)
# Conflicts:
# api/streaming.py
# static/messages.js
# static/ui.js
* fix(streaming): code-aware inline-thinking extraction + position-aware unclosed handling
Codex deep-review caught two regressions in the leading-only -> full-scan
rewrite (both silent data-mangling on the persist/reload path):
1. Code-span unawareness: the scanner only protected triple fences, so a
literal <think> in an inline single-backtick code span or an indented
(>=4-space/tab) code block got silently extracted into reasoning. Added
_inline_thinking_indented_code_at + inline-backtick tracking (Python +
the JS twin _thinkingIndentedCodeAt), so all three code contexts now keep
thinking tags visible.
2. Unclosed-tag truncation: any unmatched open tag moved the trailing prose
into reasoning. Now position-aware — a LEADING unclosed block (cut off
mid-thought) is still reasoning (#3455 intent), but an unclosed tag AFTER
visible content stays visible so literal typed tags don't truncate prose.
Gated partial handling on the previously-unused options.streaming param
(live streaming keeps 'still thinking' behavior; persist/reload does not).
Updated 2 tests that pinned the buggy behavior + added 4 regression tests
(inline-backtick, indented-code, mid-body-unclosed-visible, leading-unclosed-
extracted). Updated the node driver harness to include the new helper.

* fix(streaming): recognize fenced code blocks indented 1-3 spaces
Codex round-3: a fence indented 1-3 spaces is valid Markdown but the fence
detector only matched at column 0, so a literal think tag inside such a fence
(not 4+-space indented code either) was still extracted. Both detectors
(_inline_thinking_fence_marker_at / _thinkingFenceMarkerAt) now walk back over
up to 3 leading spaces to a line start. Added backtick + tilde indented-fence
regression tests.

* fix(streaming): O(n) inline-thinking scan + merge separate reasoning on reload
Round-4 Codex deep-review caught two real issues in my own fixes:
1. PERF (O(n^2)): the indented-code check (_inline_thinking_indented_code_at /
_thinkingIndentedCodeAt) scanned to line boundaries at EVERY character index,
plus the leading check sliced+stripped the whole prefix per unclosed tag. On
long no-newline content this was quadratic (~8.4s @ 200k, called repeatedly
on the streaming path). Replaced with incremental O(1)-per-iteration line
state (_line_is_indented_code / _lineIsIndentedCode evaluated only at line
starts) + a seen_nonspace flag. 200k now extracts in ~55-140ms.
2. RELOAD reasoning-drop: renderMessages() seeded the shared extractor with ''
so a message with BOTH an inline <think> block AND a separate m.reasoning
payload showed only the inline part — the separate payload was dropped
because the !thinkingText worklog resolution was then skipped. Now seeds with
the message's direct reasoning (m.reasoning_content||m.reasoning||...) so the
two MERGE (deduped); separate-only reasoning is preserved without promoting
it into visible prose.
Python + JS twins kept line-for-line parity. Added merge + perf + reload
regression tests; updated the reload structure test and the node driver harness
for the renamed helper.

* fix(streaming): revert reload reasoning-seed; keep O(n) perf fix
Codex round-4 finding #2 (seed renderMessages' inline extractor with
m.reasoning so a separate payload merges) turned out to VIOLATE a deliberate
architectural invariant pinned by test_issue2565 +
test_sprint42: the reload content-extraction path must NOT touch
m.reasoning/m.reasoning_content — reasoning metadata is owned exclusively by
the Worklog Thinking Card path (_worklogReasoningTextFromMessage /
_assistantReasoningPayloadText), never conflated with inline-content
extraction (which would risk promoting provider reasoning into final-answer
prose). Reverted the ui.js seed to the PR's original `thinkingText` arg.
The inline+separate merge is still a genuine extractor capability (exercised
by the live streaming path via liveReasoningText) and is covered by a unit
test, just not invoked from the reload render path by design.
The O(n) perf fix (finding #1) and the code-awareness + position-aware
unclosed handling (rounds 1-3) are all retained.
Co-authored-by: rodboev <rodboev@users.noreply.github.com>
* fix(streaming): only lstrip extracted content when a leading block was removed
Codex round-5 catch: the extractor unconditionally lstripped the final content
(.lstrip() / .replace(/^\s+/,'')) even when NO thinking block was extracted, so
an assistant reply that legitimately starts with an indented code block or blank
lines lost its leading whitespace on live display, reload, and persistence. This
was a real regression vs master (master returned non-thinking content unchanged).
Now track leading_removed (set only when a LEADING thinking block/prefix is
actually extracted) and lstrip only in that case. Mid-body / no-thinking content
keeps its exact leading whitespace. Python + JS twins kept in parity; added
backend regression tests (indented-first preserved, leading-blank preserved,
leading-think still strips).
Co-authored-by: rodboev <rodboev@users.noreply.github.com>
* fix(streaming): reconnect restore prefers raw inflight accumulator
Codex round-6 CORE catch: on reconnect, the single-live-message restore used
(_liveInflightAssistant.content || ''). Because the PR now splits a leading
unclosed <think> into empty content, restoring from the split content dropped
the open tag — so a later </think> token leaked into the visible reply and
corrupted the live accumulator. Restore from
(_fullInflightAssistant || _liveInflightAssistant.content || '') so the raw
open tag survives reconnect and the accumulator stays correct. Added a
reconnect-restore regression test.

* fix(#3401): resolve 4 deep-review regressions (inline-think, reconnect-dup, neon skin, busy-gate worklog)
Deep review (Codex diff-vs-master + live-browser drive) of the live-to-final refactor
surfaced 4 regressions vs master that the rewritten suite no longer guarded:
1. Inline <think>…</think>answer reasoning vanished — _assistantReasoningPayloadText
used $-anchored regexes so a leading think block + visible answer extracted nothing
and the Thinking card never rendered. Removed the 3 $ anchors to match the
(non-anchored) display stripper. Live: inline-think thinking-only turn now renders.
2. (CORE) reconnect/reload duplicated the live reply — _rememberRunJournalCursor advanced
a closure-local seq but never wrote INFLIGHT[activeSid].lastRunJournalSeq, so a reload
replayed the journal from after_seq=0 over restored lastAssistantText. Now mirrors the
cursor onto INFLIGHT + schedules a throttled persist.
3. Neon skin silently broke — PR deleted the :root[data-skin="neon"] CSS but left Neon in
the picker. Restored the neon CSS block from master.
4. Settled tool-worklog rebuild gated purely on !S.busy — dropped every prior settled
turn's worklog when renderMessages re-ran during an active stream (switch-back to an
in-progress session). Restored master's !S.busy || (S.toolCalls && S.toolCalls.length).
Live: busy re-render now preserves tool cards (4→4, was 4→0).
Live-verified all 4 + confirmed #3709/#3592 invariants still hold (1 thinking card, none
below footer; distinct siblings preserved). + tests/test_issue3401_deep_review_fixes.py (7).
* test(#3401): realign 3 stale source-shape assertions to the deep-review fixes
Fix commit changed two source literals that existing stage tests scanned for:
- test_live_activity_timeline.py (x2): split anchor 'if(!S.busy){' → the restored
'if(!S.busy || (S.toolCalls&&S.toolCalls.length)){' guard (fix 4).
- test_run_journal_frontend_static.py: 'after_seq=0' not in source — fix 2's comment
contained that literal; rephrased the comment to 'the zero floor (after_seq of 0)'.
Intent of all three assertions unchanged; only the matched string updated. No code
behavior change.

* fix(#3315): surface compression-exhausted/no-final-answer turns as errors (#3316)
When Hermes Agent exhausts context compression in a long tool-heavy turn, the
streamed result can end on a tool result / assistant(tool_calls) turn with no
final assistant answer. WebUI was finalizing that as a completed response.
Now _session_lacks_final_assistant_answer() + _agent_result_terminal_failure()
classify these as terminal failures and surface an apperror instead. The
compression session-id migration + pre-compression snapshot now run BEFORE the
terminal-failure return (ordering bug from the prior hold) so state stays
consistent when exhaustion fires after the agent rotated session_id.

## Release v0.51.266 — Release IH (stage-r16)
One agent-authored APPROVED fix + two un-held streaming/SSE fixes.
### Fixed
| Issue/PR | Author | Fix |
|----------|--------|-----|
| #3635 (#3637) | @nesquena-hermes (nesquena APPROVED) | Composer profile chip reads `S.activeProfile` again — a #3331 regression keyed it on the loaded session's profile, so opening a cross-profile session made the chip disagree with the dropdown checkmark and misrepresent where the next message routes. #3331's project/session-op scoping is unaffected. |
| #3587 (#3605) | @rodboev | Reasoning persists to the correct intermediate assistant message in multi-turn tool flows. The index only advanced in `on_interim_assistant` (suppressed for contentless tool-call messages) → post-tool reasoning was mis-attributed; it now also advances at the `on_tool` boundary, guarded against over-increment. **(un-held — finding resolved)** |
| #2660 (#3558) | @franksong2702 | Session-event SSE no longer wakes every tab across profiles and never drops a relevant refresh — profile attached when known, root/`default` aliases stay unscoped, and the `maxsize=1` queue falls back to unscoped refresh-all on a profile-mismatch coalesce. **(un-held — both findings resolved)** |
### Gate
- Full pytest suite: **7770 passed, 0 failed**
- ESLint: CLEAN · ruff: CLEAN · browser-smoke: CLEAN
- Codex (regression): **SAFE TO SHIP** — chip matches dropdown/routing (no #3331 scoping regression), reasoning-index advance composes with the agent's tool/interim callback ordering, session-events coalesce safely with no dropped refresh and no profile data leak (`/api/sessions` still server-side filtered).

| #3432 (#3532) | @franksong2702 | Normalize the recall-prefill terminal `user` turn so WebUI doesn't send adjacent `user` roles to strict chat templates (Mistral/Gemma/Jinja). `_normalize_prefill_messages_before_user_turn()` in both `streaming.py` + `gateway_chat.py`; drops only the terminal user tail, preserves assistant/system/mid-list context. **Rebased onto master** (was CONFLICTING). |
| #2558 (#3516) | @rodboev | "Reveal in file manager" now translates container workspace paths (`/workspace`) back to the host mount path for Docker deployments (traversal-safe via `safe_resolve` + sibling-prefix guard). |
### Changed
| Issue/PR | Author | Change |
|----------|--------|--------|
| (#3539) | @Lyr-GW | Completed the Chinese (Simplified) `zh` localization (MCP controls, tool-list pagination) with all interpolations preserved, and the language dropdown now applies the locale **instantly** on change. |
### Review fix absorbed (Codex)
#3539 also added an `allowed=['en','zh']` filter to the Settings language dropdown, which dropped the 9 other shipped locales (it/ja/ru/es/de/pt/ko/fr/tr) — and since save falls back to `en` when the select has no matching option, an existing user of those locales would be **silently reset to English** on a Settings save. Removed the filter (dropdown enumerates all `LOCALES` again, matching master); partially-translated locales fall back per-key to English at render. + regression test `test_issue3539_language_dropdown_all_locales.py`.

## Release v0.51.261 — Release IC (stage-r11)
Live Todos panel via an explicit `todo_state` SSE contract.
### Fixed
| Issue/PR | Author | Fix |
|----------|--------|-----|
| #3373 follow-up (#3454) | @v2psv | The Todos side panel now tracks `todo` tool state **live during an active run** instead of staying stale until settle / rolling back on a mid-stream reload. A dedicated `todo_state` SSE event sends a full, redacted, idempotent snapshot on todo-tool completion (no more truncated `tool_complete.preview`); the same `api.todo_state` parser feeds live + cold-load; live snapshots persist into INFLIGHT so reload/reattach restores the panel; cold-load vs INFLIGHT reconciled by timestamp (incl. the `coldTs===0` compressed-session edge); legacy reverse-scan kept as fallback for old servers. |
### Gate
- Full pytest suite: **7692 passed, 0 failed**
- ESLint: CLEAN · ruff: CLEAN · browser-smoke: CLEAN
- Codex (regression): **SAFE TO SHIP** — verified the new `todo_state` SSE handler composes with existing dispatch (no double-subscribe), INFLIGHT persistence is cleared on terminal/cancel (composes with discard_session + turn-journal), timestamp reconciliation can't let a stale local snapshot win, redaction holds, the legacy reverse-scan fallback still works with no double-render, and the `models.py` change is todo-scoped (no CLI-classification interaction).

## Release v0.51.259 — Release IA (stage-r7)
Two ship-ready @rodboev bug-fixes from today (the clean subset of the prioritized 6).
### Fixed
| Issue | Fix |
|-------|-----|
| #3582 | **Edge-TTS playback no longer has a ~31s delay / playback error** — `_handle_tts` streamed audio without `Content-Length` on an HTTP/1.0 server; audio is now buffered and sent with an exact `Content-Length`. |
| #3583 | **CLI-bridge message reconstruction strips orphaned `tool_calls`** (assistant `tool_calls` with no matching `tool` response, left by an aborted bridge) so the next request no longer 400s on strict providers. |
### Held back from the 6-PR batch (Codex regression gate caught a real defect in each)
- **#3586/#3603** (`is_cli_session_row` reclassification) — CORE: messaging rows become non-CLI, but the sidebar open path only imports when `is_cli_session`, so opening a Discord/Telegram session shows a transient stub and the next send 404s on `/api/chat/start`. Needs a client import-gate fix + live verify. **Held.**

- **#3587** (intermediate reasoning) — `on_interim_assistant` is suppressed upstream for contentless tool-call assistant messages (`run_agent.py:3834`), so advancing the reasoning index there never fires at tool-call boundaries → mis-attribution. **Held.**

## Release v0.51.257 — Release HY (stage-r5)
Two rebased ★★★ fixes.
### Fixed
| Issue | Author | Fix |
|-------|--------|-----|
| #3546 | @rodboev | **"Refresh Models" on a provider card no longer returns "Error: Not found".** Sent `POST /api/models/refresh` but no route matched (404). Added the route, wired to the existing `invalidate_provider_models_cache(provider_id)`. |
| #3548 | @franksong2702 | **Credential self-heal no longer writes to a dead `SessionDB` handle.** A credential-refresh evicted/closed the cached agent, but the retry rebuilt a new agent from kwargs still holding the old closed `SessionDB` → persistence silently targeted a dead handle. Per-request `SessionDB` construction centralized + refreshed on the retry. |
### Dropped from this batch
- **#2660** (session-event SSE profile scoping) — the Codex regression gate found **two SILENT dropped-refresh bugs** the scoping introduced: (1) the `maxsize=1` subscriber-queue coalescing overwrites a pending profile-A event with a profile-B event → A-tabs filter B out and never refresh for the A change; (2) renamed-root/`default` alias mismatch (backend `_profiles_match` treats them equal, the client filter uses a literal `!==`). A dropped refresh (stale sidebar) is worse than the extra refreshes the PR removes. Held with `changes-requested` + repros + the fail-safe fix (coalesce to unscoped on a profile mismatch; normalize root aliases).

## Release v0.51.256 — Release HX (stage-r4)
Performance — bound WebUI memory growth & idle CPU on large installs.
### Fixed
| Issue | Author | Fix |
|-------|--------|-----|
| #3506 | @nesquena-hermes (reported w/ profiling by @djenttleman) | On a large install (~615 sessions / 40k messages / 454 MB state.db) the WebUI process climbed ~100 MB → ~1.5 GB RSS over days and held high idle CPU. Three root causes fixed: (1) `session_lifecycle._sessions` grew unbounded → new `discard_session()` drops the entry at agent-eviction boundaries, only when no in-flight commit / no uncommitted memory work (retry invariant preserved); (2) cache caps now operator-tunable (`HERMES_WEBUI_AGENT_CACHE_MAX` default 50→25, `HERMES_WEBUI_SESSIONS_MAX`); (3) GatewayWatcher computes a cheap fingerprint before the expensive per-session `MAX(messages.timestamp)` projection and only re-projects on change. |
### Rebase + review notes
- Rebased onto current master; the code diff was verified **byte-identical to the nesquena-APPROVED head** at rebase time (only CHANGELOG re-resolved).
- The Codex regression gate then surfaced **two correctness gaps** the approval didn't catch, both fixed here with regression tests:
1. **Watcher fingerprint missed same-count transcript rewrites.** `/retry`,`/undo`,`/compress` (`SessionDB.replace_messages`) rewrite messages with new timestamps but can leave `message_count` unchanged → stale sidebar `last_activity`. Fixed with a **per-session** grouped message aggregate (`id, count, user_count, MAX(timestamp)`) over the same non-excluded sessions (a global MAX would miss a rewrite of an older, non-newest session); cron/webui stay excluded so idle churn still doesn't re-project.
2. **LRU agent-cache eviction could close a live worker's agent** (`popitem(last=False)`, liveness-blind — pre-existing, but the lower 50→25 cap made it more likely). Eviction now snapshots `ACTIVE_RUNS` session_ids (before the cache lock — no nested lock) and skips live sessions, deferring (temporarily exceeding cap) rather than closing a live agent.

## Release v0.51.247 — Release HO (stage-q19)
Backend correctness fix.
### Fixed
| Issue | Author | Fix |
|-------|--------|-----|
| #3505 | @franksong2702 | **Reasoning effort is coerced to a level the active model/provider actually supports** before each request, instead of being sent verbatim and rejected. `openai-codex` `gpt-5` no longer gets `max` (→ `xhigh`); `o1`/`o3`/`o4` clamp to `low`/`medium`/`high`. Coercion only steps *down* (never escalates); `none`/unset preserved. The capability filter is applied across heuristic / models.dev / Copilot / LM Studio paths. |
This is the narrow, correct fix for the detection gap that #3431 tried to address by removing the chip-visibility gate (which we shelved). The chip-visibility gate is **untouched** (Codex confirmed) — `get_reasoning_status`/`_applyReasoningChip` still hide the chip for unconfirmed models.
### Review fix absorbed (Codex + self-flagged)
The first cut **dropped** a configured effort for *unrecognized* models, because capability detection returns `[]` for both "known-unsupported" and "simply-unknown" (custom providers, aggregator-rewritten ids, new releases) — that's a behavior change vs master (which sent it verbatim) and would silently disable reasoning. Fixed: an **empty** capability set now **preserves** the configured effort (provider stays the final authority; worst case = the same rejected request master already produces, i.e. no regression). Known-bad clamps return *non-empty* filtered sets, so they still degrade correctly. Nathan chose this "preserve-for-unknown" behavior. + regression test.

## Release v0.51.237 — Release HE (stage-q8)
Phase 3 MEDIUM-ring pick (3-factor framework): a real concurrency/state-consistency fix from a regular contributor (@franksong2702, ★★★ 38 merges). The hardest review of the sweep — the dual gate caught **two** silent data-loss bugs across two review rounds.
### Fixed
| PR | Author | Fix |
|----|--------|-----|
| #3475 | @franksong2702 | Cancelling a live turn immediately after send now reliably stops the worker and settles the session to a cancelled state (was: spinner over a blank page). `cancel_stream()` falls back to the live active-run registry (`ACTIVE_RUNS`) + session agent cache when `STREAMS` has already detached, so the worker still receives `interrupt("Cancelled by user")`. `/api/session` reports run-journal active state from the live registry instead of trusting a persisted `active_stream_id`. |
### Pre-release dual gate caught TWO silent data-loss bugs (both fixed + regression-tested)
The PR's refactor moved `agent.interrupt()` ahead of the partial-text/reasoning/tool-call snapshot, and that snapshot was no longer under `streams_lock`:
1. **Codex round 1** — the worker's `finally` (which pops `STREAM_PARTIAL_TEXT`/`STREAM_REASONING_TEXT`/`STREAM_LIVE_TOOL_CALLS` under `STREAMS_LOCK`) could clear those buffers the instant `interrupt()` wakes it, so a cancelled turn **silently lost its already-streamed text**. (Opus reviewed the original and said ship — it assumed the snapshot was still lock-protected; the stale comment claimed so but the code wasn't. Verified against the actual code → Codex was right.)
2. **Codex round 2** — my first fix only snapshotted on the `STREAMS`-present path; the detached `ACTIVE_RUNS`-only path (the case this PR adds) still lost text. Fixed by hoisting the snapshot above the `if stream_present` branch so it runs unconditionally under the lock.
Both fixes have regression tests **verified to fail against the buggy versions** (`test_cancel_preserves_partial_text_when_interrupt_pops_buffers` + `test_cancel_preserves_partial_text_on_detached_active_run_path`).

## Release v0.51.235 — Release HC (stage-q5)
Single fix in the data-sensitive transcript-merge path, with a Codex-found MUST-FIX applied.
### Fix
| PR | Author | Fix |
|----|--------|-----|
| #3468 | @jasonjcwu | `_find_current_user_turn` returns the **last** matching user turn instead of the first, so post-compression `result_messages` (which carries the full history) no longer replays the entire conversation when the user repeats a similar question (137-msg session → 89 duplicate replays). |
### Pre-release review caught a CORE issue (fixed before ship)
Codex's regression gate found that a naive last-match could be overridden by a **synthetic `role:"user"` continuation prompt** (the agent loop injects "Continue"/empty-recovery nudges — verified at `conversation_loop.py:1763/4183/4356`) that only *substring*-matches the user text — anchoring the merge **past** the real turn and dropping the assistant/tool output in between. Applied the fix: track **strong** (exact `_looks_like_current_user_turn`) and **weak** (substring) matches separately and return `last_strong → last_weak → fallback`. The real turn (strong) always wins over a later synthetic continuation (weak).
Opus reviewed the original and said ship; the applied fix is strictly safer than what it reviewed.

* Release v0.51.230 (stage-p14): extract <think> to m.reasoning #3455 + LLM Wiki last-writer (#1257)
Salvage of #3455 (@gsurenull): dropped the stale api/config.py bits (MiniMax-M3 +
SCHEMA_VERSION 3->4 — both already on master via #3374). Kept the two genuine fixes:
(1) _splitThinkFromContent persist-path extraction of inline <think> blocks into
m.reasoning (fixes 30-50% session bloat for reasoning-only providers like MiniMax-M3);
(2) LLM Wiki status Last-writer 3-tier fallback (was always 'Not available' since #1257).
Added 9 Node-driven think-split regression tests (data-loss guards: content-before/after
preserved, unclosed blocks intact, lookalike tags not extracted).
* fix(#3455): renderer-matching think extraction + wiki symlink/bounded-read guards (Codex review)
Codex review of stage-p14 found 3 SILENT bugs, all fixed:
(1) DATA-LOSS: _splitThinkFromContent's Pass-2 whole-body scan extracted a CLOSED literal
<think>...</think> from visible prose/code (e.g. inside a fenced code block) into m.reasoning,
emptying it — more aggressive than the renderer (which only strips LEADING blocks). Removed
Pass 2; extraction now matches _streamDisplay semantics (leading-only, loop captures
consecutive leading blocks). +fenced-code regression test.
(2) PRIVACY: _llm_wiki_last_writer followed symlinked .md pages resolving OUTSIDE the wiki
(is_file follows symlinks), leaking external frontmatter. Now requires resolved path under
wiki_root. +symlink-containment regression test.
(3) CONTRACT/PERF: replaced full read_text() with bounded line-by-line reads (frontmatter
block only / capped log-heading scan), never page bodies.
* fix(#3455): think-split is leading-single (renderer-matching) + fix 2 stale source-match tests
Codex re-review finding #2: looping consecutive leading blocks diverged from the renderer
(_streamDisplay/_parseStreamState strip ONE leading block). Now extracts exactly one leading
block. Also updated 2 tests that asserted pre-split implementation strings:
test_live_stream_tokens_persist (content:assistantText -> content:split.content, invariant
preserved) and the consecutive-blocks test. NOTE: Codex finding #1 (client-only split doesn't
persist server-side) is a separate architectural decision pending Nathan.
* feat(#3455): split inline <think> server-side before s.save() so persisted file is compacted (Codex #1)
Codex finding #1: the think-split was client-only, so the SAVED session file still
carried inline <think> blocks (bloat) — the fix only compacted the browser copy.
Added _split_thinking_from_content (api/streaming.py), a server-side twin of the JS
helper with identical leading-only/single-block semantics, applied to the final
assistant message before s.save() (extended the existing reasoning-persist block).
Merges with on_reasoning-stream reasoning. +8 backend-parity regression tests covering
the mid-body-code-block data-loss guard, unclosed-intact, single-leading, none-content.
* test: update 3 save-path source-assertion tests for #3455 server-side think-split
The backend think-split (api/streaming.py reasoning-persist block) changed the literal
code shape + grew the pre-save block, breaking 8 source-assertion tests that anchor on it:
- test_sprint42: assert _rm['reasoning']=_reasoning_text -> now _merged_reasoning/_existing_reasoning
+ _split_thinking_from_content present (intent preserved: reasoning persisted before save).
- test_pr1318 (6) + test_pr1341: re-anchored the locator from the changed 'if _reasoning_text
and s.messages:' line to the stable 'Persist reasoning trace in the session' comment marker;
bumped the 1341 byte-distance limit 15000->16000 (the test self-documents bumping on legit
pre-save growth). All behavioral invariants (reasoning persisted + context fields before save)
unchanged.

* fix: respect profile toolset/skill config on WebUI streaming worker (#3294)
The streaming agent runs on a detached worker thread that does not inherit
the per-request thread-local profile context (set from the hermes_profile
cookie on the HTTP handler thread). On that worker, the ambient get_config()
resolves via get_active_profile_name() which falls back to the process-global
_active_profile (usually 'default'). A session under a non-default profile
with an empty platform_toolsets.cli therefore loaded the DEFAULT profile's
full toolset list, inflating a tools-disabled profile's prompt from ~400 to
~15K input tokens.
Add api.config.get_config_for_profile_home() — a race-free direct disk read
of an explicit profile home's config.yaml (no shared-cache mutation), which
defers to get_config() when the requested home matches the ambient path so
in-memory test overrides are preserved. The streaming worker now resolves
_cfg from the session's own profile home, fixing toolsets, prefill context,
and fallback chains in one place.

* fix: reject cross-script drifted auto-generated session titles (#3293)
The title-language mismatch guard only knew two states: German (de) or empty,
and _title_language_mismatch early-returned False whenever the user start
wasn't German. So an English conversation whose LLM-generated title came back
in Chinese / Spanish / Russian sailed through and persisted with
llm_title_generated=true. The German case was the only one covered because
that's the one prior report it was built for.
Generalize from a German-specific binary to a language-agnostic cross-script
check. Add _script_counts() + _dominant_script() (cheap, dependency-free
Unicode-block classification: latin / cjk / cyrillic / arabic / hebrew / greek
/ devanagari). _title_language_mismatch now rejects a title that introduces a
substantial amount (>=35% of alphabetic chars, min 2) of a script different
from the conversation start's dominant script — so short titles that embed a
borrowed Latin technical term still trip, while an English title with a single
foreign place-name does not. The legacy German->English same-script heuristic
is preserved verbatim.
Kept api/streaming.py ASCII-only (the test_title_generation_source_has_no_cjk_
literals guard) — all CJK examples live in the test file, not the source.

* fix: prune orphaned imported-CLI sidecars from the WebUI sidebar (#3238)
When a CLI/agent session is opened in WebUI it gets a WebUI-owned sidecar
(webui/sessions/<id>.json + _index.json row) so it can render and reopen;
all_sessions() then returns it independently of the agent state.db. If the
user later deletes that session from the CLI / local Hermes storage, nothing
pruned the sidecar — the merge loop only overlays CLI metadata when a matching
state.db row exists and otherwise continues, so the stale row lingered in the
sidebar indefinitely (there is no WebUI delete affordance for CLI rows).
Add api.models.agent_session_row_exists(): an exact, uncapped existence probe
against the state.db sessions table. The sidebar merge loop now drops a row
that is_cli_session_row + not WebUI-native + absent from cli_by_id + whose
state.db row is genuinely gone, and calls prune_session_from_index() so
_index.json self-heals.
The state.db probe is deliberate: get_cli_sessions() caps at
CLI_VISIBLE_SESSION_LIMIT (20), so a still-existing session can fall out of
that window and look deleted — pruning on cli_by_id absence alone would delete
live sessions. WebUI-native rows with a CLI ancestor are never pruned, and any
probe error degrades to keep-the-row so a transient failure can't lose data.
Closes#3238

* fix: count pin quota by visible session lineage
* docs(changelog): v0.51.222 — backend bugfix batch (#3293 title drift, #3238 sidecar prune, #3288 pin lineage)
* fix(pins): forks count as own pin lineage, not collapsed to parent (#3288 Codex follow-up)
Codex review of the batch found a pin-limit UNDERCOUNT: _session_row_lineage_root_id
followed any parent_session_id to the root, but /api/session/branch creates
independent visible fork sessions that also carry parent_session_id (session_source=
'fork'). Two pinned forks of the same parent collapsed to one quota lineage, letting
a user exceed pinned_sessions_limit with no 400. Fix: a fork returns its own id as
its lineage root (it's a separately-visible session); only compression/continuation
rows still collapse to a shared root. Adds a regression test with two pinned forks +
the parent counting as three distinct lineages, and confirms the existing
pre-compression-snapshot collapse case still passes.
* test(pins): update #2508/#2821 source-match tests for #3288 lineage rename
#3288 replaced the raw-session-id pin counter (pinned_ids set) with a
visible-lineage counter (pinned_lineage_ids via _visible_pinned_lineage_ids over
persisted_rows/candidate_rows). Two pre-existing source-string-matching tests
asserted the OLD implementation literals (pinned_ids = {, _session_field(existing,
session_id...), len(pinned_ids) >=). Updated both to assert the new mechanism while
preserving the invariants they actually guard: snapshot computed BEFORE LOCK (no
all_sessions()-inside-LOCK deadlock), quota filtering via the shared
_session_counts_toward_pin_quota helper, and the limit/400 guard. Behaviour
unchanged; these were implementation-detail assertions, not behaviour tests.

Consecutive user turns (session-context prefill + actual message) made models
with strict chat templates (Mistral, Gemma via llama.cpp) reject the request
with a Jinja 500. Move the platform/delivery context (connected platforms, home
channels, scheduled-task delivery hints) from _webui_session_context_message
(a prefill user message) into _webui_delivery_context_prompt, appended to the
ephemeral system prompt. Session framing stays in _webui_surface_context_prompt.
Context is preserved — just role-alternation-safe. Closes#3276.
Co-authored-by: aether-agent <aether-agent@users.noreply.github.com>
_merge_display_messages_after_agent_result shared one _emitted set between
context-backfill rows and the visible-display backbone; _message_identity
ignores timestamps, so a second identical visible user turn was suppressed as
already-emitted. Now the display backbone is always appended in order; a
separate _context_inserted set + the _display_id_set guard dedupe only the
spliced-in context rows. Adds a regression test with two identical visible
user turns + a context-only gap.
Backfill model-context turns into the visible transcript before saving the
latest reply while keeping hidden [context compaction] markers out of the
visible transcript, so sidebar/header message counts no longer collapse a
compacted gateway session to a 2-message conversation. Resolves the
transcript-loss regression the v0.51.197 Codex gate flagged on the original.

Closes#3106. Adds /api/session/title/regenerate endpoint + session-action
menu item. Preserves chronology (touch_updated_at=False), guards read-only
and imported sessions, syncs to state.db when Insights sync enabled.
Maintainer refinement (Opus SHOULD-FIX): scope the is_imported guard to the
regenerate action only instead of broadening the shared _isReadOnlySession()
helper, which also gates rename/pin/archive/move/fork. Matches the backend
403 guard. Test updated to assert the scoped shape.
The default-only context_length guard compared model.default to the session
model with exact string equality. But model.default and the session model can
be stored in equivalent-but-different shapes (bare 'claude-opus-4.8',
provider-prefixed 'anthropic/claude-opus-4.8', or '@anthropic:claude-opus-4.8').
An exact compare wrongly treats the actual default model as non-default and
drops its configured context_length cap for provider-prefixed configs.
Add api/routes._model_matches_configured_default(session_model, cfg_default,
provider) that normalizes all three shapes, and use it at all 6 guard sites
(routes resolver + the 5 api/streaming.py sites: live-usage snapshot, persistence
_skip_cc_cl, persistence fallback _apply_cfg_ctx, SSE-done _dropped_stale_cap_sse,
SSE fallback _apply_cfg_ctx). Imported function-scoped in streaming to avoid the
routes<->streaming module-level circular import. 10 helper unit tests + a
behavioral test that a prefixed default still receives its cap.

The threshold-rescale block runs unconditionally after the fallback and
references _skip_cc_cl/_cc_cl, which were only defined inside 'if _cc_for_save:'.
On the no-compressor path (fresh agent / interrupted stream) that raised
UnboundLocalError (caught by test_issue1857_usage_overwrite). Hoist both inits
above the block (no-op rescale when no compressor). Also widen the #1318
source-assertion test to accept the widened fallback gate (still asserts the
falsy-check invariant).
Co-authored-by: allenliang2022 <allenliang2022@users.noreply.github.com>
Codex regression gate (+Opus, both independently) found the default-only guard
dropped the stale compressor cap but two sibling paths stayed inconsistent:
1. Per-turn persistence: fallback resolver only ran when context_length was
falsy, so a previously-persisted stale 232K survived forever on non-default
sessions. Now also runs when _skip_cc_cl, and rescales threshold_tokens to
the recomputed real cap (or clears it).
2. Terminal SSE 'done' payload: re-emitted the stale compressor threshold, so
messages.js overwrote S.lastUsage and the indicator reverted on stream end.
Now rescales threshold to the resolved window when the stale cap was dropped.
Added 3 source-structure regression tests pinning both fixes; bumped the brittle
test_pr1341 distance limit 13000→15000 (+ noted it should become structural).
Co-authored-by: allenliang2022 <allenliang2022@users.noreply.github.com>
The default-only guard corrected context_length to the real per-model cap
(e.g. 1M for claude-opus-4.7-1m) but left threshold_tokens pointing at the
ContextCompressor's stale value (computed from the global 232K cap → 197.2k
@ 85%). UI then showed 'auto-compress at 197.2k / 1M' which is misleading.
Rescale threshold_tokens by the real/orig ratio so the displayed trigger
reflects the actual window (e.g. ~850k @ 1M).
NOTE: this only corrects the SSE display payload. The real auto-compress
trigger lives inside ContextCompressor in hermes-agent (agent_init.py:1446
constructs it with the global cap). A full fix requires a parallel change
upstream — tracked separately.
_live_usage_snapshot() runs on every metering tick (~10x/sec while streaming).
The #3256 default-only guard recomputed get_model_context_length() there on
every tick for non-default models, which does a config read + potential
metadata/network probe — freezing claude-opus-4.7-1m streams while the default
model (4.8) stayed fast (guard not triggered for it). Resolve the real cap at
most once per stream via _real_ctx_cache. Backend-only, no frontend changes.
Re-applies cb0065eb + b34311b3 (context_length default-only guard) which were
dropped by the upgrade reset to v0.51.185. Fixes 4.7-1m context window showing
as stale global cap (232K) instead of real 1M metadata. Backend-only: touches
api/routes.py + api/streaming.py, zero frontend/render changes.
Instead of using len(visible_after)-1 (which points to the last visible
message and gets pushed behind the render window as more turns accumulate),
find the last [CONTEXT COMPACTION] marker in s.messages and compute the
anchor from visible messages before it.
This keeps the compression reference card at the correct boundary even
after 50+ subsequent turns have scrolled the render window past the old
anchor position.
Fixes a bug where the assistant's output message appeared to disappear
after automatic context compression because the reference card was placed
at the wrong position.
When API server runs append messages directly to state.db, reconcile WebUI sidecar sessions with those canonical rows across API responses, model-facing streaming context, and active browser refresh.
Add append-only state.db merge helpers, metadata-only counts for refresh polling, and regression coverage for API visibility, context incorporation, and frontend refresh behavior.
