# Hermes Web UI -- Changelog
+## Unreleased
+
+### Fixed
+
+- **Session jump button locale parity** — localized the opt-in Start/End
+ session jump labels, aria labels, and Appearance setting copy for
+ ja/ru/es/de/zh/zh-Hant/pt/ko instead of leaving English fallbacks in
+ otherwise localized UIs. (`static/i18n.js`,
+ `tests/test_session_jump_buttons.py`) Closes #1938.
+
## [v0.51.30] — 2026-05-08 — 3-PR contributor batch (Release G: offline recovery + PWA hardening + opt-in session jump buttons + opt-in endless-scroll)
### Added (3 PRs, all from @ai-ag2026)

Subject: [PATCH 05/17] fix(#1937): close endless-scroll prefetch vs Start-jump
race with generation-token + mutex
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The originally-proposed fix (gate _ensureAllMessagesLoaded on the existing
_loadingOlder flag) does not actually close the race. By the time the
prefetch reaches its post-await body, it has already cleared the entry-
gate that reads _loadingOlder, so a same-flag check inside the resolved
callback would be a no-op for an in-flight request.
The actual fix is two-pronged:
1. New module-scoped _messagesGeneration counter, bumped every time
S.messages is wholesale-replaced. _loadOlderMessages snapshots it
BEFORE its await and re-checks after — if it changed, the prepend
is aborted. This is the canonical async-invalidation pattern.
2. _ensureAllMessagesLoaded now claims the _loadingOlder mutex around
its body so a new prefetch cannot start mid-replace and concurrent
ensure-all calls (rapid double-click on Start) serialize cleanly.
It bumps the generation token before mutating S.messages, yields
until any in-flight prefetch finishes, and resets _oldestIdx so a
subsequent prefetch cannot request stale older messages.
Also adds the same-session / _loadingSessionId guards that the original
ensure-all body was missing post-await — if the user switched sessions
mid-flight, the old code would happily overwrite the new session's
messages with the previous session's full history.
12 new regression tests in tests/test_issue1937_endless_scroll_jumpstart_race.py
lock in: generation token declaration, bump-helper presence, snapshot-
before-await ordering, post-await-abort behaviour, mutex acquisition and
finally-release, yield-then-claim ordering when a prefetch is in flight,
generation bump during the wait phase, _oldestIdx reset, and the new
session-switch guard.
Closes #1937.

+- **#1937 — Race: endless-scroll prefetch vs Start-jump's `_ensureAllMessagesLoaded` could duplicate messages.** With both `session_jump_buttons` AND `session_endless_scroll` enabled, an in-flight `_loadOlderMessages` prefetch racing with `jumpToSessionStart` → `_ensureAllMessagesLoaded` could prepend a duplicate page if the prefetch resolved last. The naive fix suggested in the report (gate ensure-all on the existing `_loadingOlder` flag) does not actually close the race — by the time the prefetch reaches its post-await body, it has already cleared the entry-gate that reads `_loadingOlder`, so a same-flag check inside the resolved callback is a no-op. The actual fix is a generation-token + mutex pair: (1) `_loadOlderMessages` snapshots a new module-scoped `_messagesGeneration` counter BEFORE its `await api(...)` and re-checks it after, aborting the prepend if any wholesale-replace bumped the token mid-flight; (2) `_ensureAllMessagesLoaded` claims the `_loadingOlder` mutex around its body (so a NEW prefetch cannot start mid-replace, and concurrent ensure-all calls from rapid double-clicks on Start serialize cleanly), bumps the generation token before mutating `S.messages`, yields until any in-flight prefetch's `finally`-block releases the mutex, and resets `_oldestIdx` so a subsequent prefetch cannot send a stale `msg_before` index. Also adds the same-session and `_loadingSessionId` guards that the original ensure-all body was missing post-await.

+"""Regression test for issue #1937 — endless-scroll prefetch vs Start-jump race.
+
+When both ``session_jump_buttons`` and ``session_endless_scroll`` opt-ins
+are enabled, ``_loadOlderMessages`` (the endless-scroll prefetch) can be in
+flight when the user clicks the Start jump pill, which calls
+``_ensureAllMessagesLoaded``. If the prefetch resolves AFTER the
+ensure-all wholesale-replaces ``S.messages``, it would prepend a duplicate
+page.
+
+The fix uses two coordinated guards:
+
+1. A ``_messagesGeneration`` token that gets bumped any time
+ ``S.messages`` is wholesale-replaced. ``_loadOlderMessages`` snapshots
+ the token before its ``await`` and re-checks afterwards; if it changed,
+ the prepend is aborted.
+
+2. ``_ensureAllMessagesLoaded`` claims the existing ``_loadingOlder``
+ mutex around its body so no NEW prefetch can start mid-replace, and so
+ concurrent ensure-all invocations (e.g. rapid double-click on Start)
+ serialize cleanly. It also yields until any in-flight prefetch's
+ ``finally`` clears the flag before claiming the mutex itself.
+
+The old fix shape suggested in the issue (spin-wait on ``_loadingOlder``
+before running ensure-all) does not actually solve the race the report
+describes: by the time the prefetch passes its entry-gate check, it is
+already past the only point where ``_loadingOlder`` is read, so a same-
+flag check inside its post-await body would be a no-op. The generation
+token is the canonical pattern for invalidating async continuations and
+is what this regression suite locks in.

# Hermes Web UI -- Changelog

+- **Gateway heartbeat stale stopped state** — treat an old root
+ `gateway_state.json` with `gateway_state: "stopped"` as an unknown /
+ unconfigured root gateway instead of a live outage, so users running only
+ profile-scoped gateways do not get a persistent heartbeat-down alert from a
+ fossilized clean-stop file. Fresh stopped states still report down. Closes
+ #1944. (`api/agent_health.py`,
+ `tests/test_issue1879_cross_container_gateway_liveness.py`)

## [v0.51.30] — 2026-05-08 — 3-PR contributor batch (Release G: offline recovery + PWA hardening + opt-in session jump buttons + opt-in endless-scroll)

Subject: [PATCH 07/17] fix: only evaluate goal hook on goal-related turns
(#1932)
The goal evaluation hook was firing on every completed assistant turn
when a goal was active, even for unrelated messages like "what time is
it". This burned the goal budget, triggered continuation prompts that
interrupted unrelated conversations, and made /goal status numbers
misleading.
Add STREAM_GOAL_RELATED and PENDING_GOAL_CONTINUATION flags to gate
the evaluate_goal_after_turn() call in the streaming loop. Only streams
started from goal kickoff (/goal ) or goal continuation are
marked as goal-related. Normal user messages skip the hook entirely.

Subject: [PATCH 08/17] fix: fix(config): skip #1776 provider peel for custom
host:port slugs
model_with_provider_context can emit @custom::: when
model_provider is derived from an OpenAI base_url authority (e.g.
custom:10.8.0.1:8080). The colon-count heuristic meant for @custom:slug:model:free
mistook those extra colons for an over-split model ID and prepended the port
segment onto the bare model (8080:Qwen3-235B), breaking WebUI while CLI/curl
stayed correct.
Detect endpoint-style slugs (IPv4/localhost/hostname + numeric port) and skip
the peel in that case. Add regression tests for IPv4, dotted hostname,
localhost, and model_with_provider_context round-trip.

Subject: [PATCH 09/17] fix: show same model from different custom providers
instead of deduplicating
When multiple custom providers expose the same model ID (e.g. baidu,
huoshan, and liantong all offering glm-5.1), only the first provider's
entry was shown in the model dropdown.
Root cause (backend): used the bare model ID as the
dedup key, so the second and subsequent providers with the same model
were silently skipped.
Root cause (frontend): stripped the @provider: prefix before
comparing, so @custom:baidu:glm-5.1 and @custom:huoshan:glm-5.1 were
treated as duplicates.
Fix:
- Backend: change _seen_custom_ids key to '{slug}:{model_id}' so each
provider's models are tracked independently.
- Frontend: add _providerOf() helper and deduplicate on the composite
(normId, provider) key instead of normId alone. Bare model IDs
(without @provider: prefix) still deduplicate on normId for backward
compatibility.

Subject: [PATCH 11/17] feat(auth): make session TTL configurable via env var
and settings.json
Add _resolve_session_ttl() with three-layer precedence:
1. HERMES_WEBUI_SESSION_TTL env var (highest priority)
2. session_ttl_seconds in settings.json
3. Default: 86400 * 30 (30 days)
Clamped to [60s, 1 year] for safety. Settings changes take effect
immediately since the function is called dynamically at each login/cookie-write.
Closes #1954

_build_native_multimodal_message() unconditionally embedded images as
native image_url parts, bypassing the agent's image_input_mode config.
Add _resolve_image_input_mode(cfg) helper mirroring the agent's
decide_image_input_mode logic, and wire it into
_build_native_multimodal_message with a new cfg parameter.
When mode resolves to 'text' (explicit aux vision config, or
image_input_mode: text), returns plain string so the agent's
existing text-mode pipeline (vision_analyze) handles images.
Closes #1959

Subject: [PATCH 14/17] test(#1947): regression coverage for
same-model-multiple-named-custom-providers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Adds tests/test_pr1947_same_model_multiple_custom_providers.py covering:
1. Two named custom providers exposing the same model id — both must
surface in the rendered groups (one bare, one @custom:slug:model)
2. Three named providers all exposing the same model — none dropped
3. Distinct-model-per-provider sanity check (still grouped correctly)
Verified the regression-detecting tests (1 + 2) FAIL against master's
api/config.py (where _seen_custom_ids was seeded from auto_detected_models
and used as a global bare-id bucket — the second provider's entry was
silently dropped) and PASS against the contributor fix on this branch.
Test 3 (distinct-models sanity) passes either way as expected.

Subject: [PATCH 15/17] fix(stage-326): preserve SESSION_TTL constant +
reconcile #1957 tests
PR #1957 deleted the SESSION_TTL = 86400 * 30 module-level constant in
favor of the new _resolve_session_ttl() helper. Two existing regression
tests pin the constant: test_auth_sessions.TestSessionPruning.test_session_ttl_is_24_hours
imports SESSION_TTL directly, and test_v050258_opus_followups.test_redirect_session_ttl_30_days
asserts the literal "SESSION_TTL = 86400 * 30" line is present in source
(guarding against the daily-kick-out regression from #1419).
Restore SESSION_TTL as the named fallback for _resolve_session_ttl(); the
new env-var/settings.json path is unchanged. Backwards-compatible.
Also fix the new TestSessionTtlResolution suite:
- Switch from pytest's `monkeypatch` fixture (incompatible with
unittest.TestCase subclasses) to setUp/tearDown env snapshotting
- Reconcile clamp tests with actual implementation: out-of-range env
values fall through to settings/default, not snap to bounds
- test_session_uses_dynamic_ttl now sets the env var so the dynamic
resolved value (3600s) is exercised rather than expecting the default
Verified: tests/test_auth_sessions.py + tests/test_v050258_opus_followups.py
21/21 pass.

Subject: [PATCH 16/17] fix(stage-326): apply Opus advisor critical +
recommended fixes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
CRITICAL: #1951 PENDING_GOAL_CONTINUATION race
Removes `PENDING_GOAL_CONTINUATION.discard(session_id)` from the
streaming worker's `finally` cleanup block. The marker is set inside
the SAME function call (line ~3328 on `goal_continue`) and the discard
in the `finally` (line ~3553) almost always raced ahead of the
frontend's SSE-receive → POST /api/chat/start round-trip, erasing
the marker before the consumer in routes.py could read it. The
consumer (`_start_chat_stream_for_session` in routes.py:6522) already
discards atomically when consuming, so removing the streaming-side
discard preserves single-use semantics and unblocks the
goal-continuation chain.
Adds tests/test_stage326_pending_goal_continuation_race.py with 5
regression guards:
1. streaming.py's finally must NOT discard PENDING_GOAL_CONTINUATION
2. routes.py consumer must check + set + discard atomically
3. PENDING_GOAL_CONTINUATION must be a set (GIL-safe single-op)
4. STREAM_GOAL_RELATED.pop must be keyed by stream_id, not session_id
5. PENDING_GOAL_CONTINUATION.add must precede the goal_continue SSE
emission in source ordering
HARDENING: #1956 composer-draft input validation
Per Opus, the POST /api/session/draft handler accepted unbounded /
arbitrary-typed text and files inputs. With the 400ms debounced
auto-save firing on every keystroke, a misbehaving client could
persist multi-MB strings into the session JSON. Adds:
- text: coerced to str if not already; clamped to 50_000 chars
- files: coerced to list if not already; clamped to 50 entries
Validation runs BEFORE the session lock acquire / save.
Adds tests/test_stage326_composer_draft_validation.py with 5 guards.
Verdict from Opus advisor on stage-326: SHIP-WITH-FIXES.
This commit applies the required + recommended fixes; #1957 hardening
fixed in a prior stage commit.

# Hermes Web UI -- Changelog
-## Unreleased
+## [v0.51.31] — 2026-05-09 — Release H (12-PR contributor batch: image-mode + race fixes + composer drafts + locale parity)
+
+### Added
+
+- **PR #1956** by @JKJameson — Persistent composer draft. The chat composer textarea (`#msg`) is now persisted per-session server-side under `Session.composer_draft = {text, files}`, so drafts survive page refreshes and sync across clients. New `POST/GET /api/session/draft` endpoints (input validation: text clamped to 50 KB, files clamped to 50 entries, types coerced to str/list — Stage-326 hardening per Opus advisor). Frontend: 400 ms debounced auto-save on textarea `input`, immediate fire-and-forget save before session switch, save on clarification card lock. `_restoreComposerDraft` guards against stale responses from rapid session switching. Co-authored by Minimax.
+
+- **PR #1957** by @hermes-gimmethebeans — Configurable session TTL. New `_resolve_session_ttl()` helper with three-layer precedence: `HERMES_WEBUI_SESSION_TTL` env var > `settings.json` `session_ttl_seconds` > 30-day default. Out-of-range values [60s, 1y] fall through to the default. Resolved dynamically at every `create_session()` and `set_auth_cookie()` call so settings changes take effect immediately without restart. The `SESSION_TTL = 86400 * 30` module constant is preserved as the named fallback (Stage-326 reconciliation: existing regression tests pin the constant; #1957 originally deleted it). Closes #1954.
### Fixed
-- **Gateway heartbeat stale stopped state** — treat an old root
- `gateway_state.json` with `gateway_state: "stopped"` as an unknown /
- unconfigured root gateway instead of a live outage, so users running only
- profile-scoped gateways do not get a persistent heartbeat-down alert from a
- fossilized clean-stop file. Fresh stopped states still report down. Closes
- #1944. (`api/agent_health.py`,
- `tests/test_issue1879_cross_container_gateway_liveness.py`)
+- **PR #1939** by @ai-ag2026 — Test-only follow-up: tightens the theme-color bridge tests so the pre-paint script must update every theme-color meta tag and remove stale media attributes; asserts the runtime theme sync updates both the canonical id tag and fallback theme-color tags; adds regression coverage that service-worker shell assets use network-first with cache fallback.
-- **Session jump button locale parity** — localized the opt-in Start/End
- session jump labels, aria labels, and Appearance setting copy for
- ja/ru/es/de/zh/zh-Hant/pt/ko instead of leaving English fallbacks in
- otherwise localized UIs. (`static/i18n.js`,
- `tests/test_session_jump_buttons.py`) Closes #1938.
+- **PR #1941** by @ai-ag2026 — Preserve chat scroll across final render. When a stream completed, the `done` handler replaced the live transcript with persisted session messages via `renderMessages({ preserveScroll: true })`. The `preserveScroll` path avoided forcing bottom-scroll, but did not preserve `scrollTop` itself; during the DOM rebuild the browser could reset `#messages.scrollTop` to `0`, sending a reader who had scrolled up to the first message. Now captures the scroll position before the rebuild and restores it for unpinned readers; pinned/near-bottom readers keep the existing bottom-follow behavior.
-- **#1937 — Race: endless-scroll prefetch vs Start-jump's `_ensureAllMessagesLoaded` could duplicate messages.** With both `session_jump_buttons` AND `session_endless_scroll` enabled, an in-flight `_loadOlderMessages` prefetch racing with `jumpToSessionStart` → `_ensureAllMessagesLoaded` could prepend a duplicate page if the prefetch resolved last. The naive fix suggested in the report (gate ensure-all on the existing `_loadingOlder` flag) does not actually close the race — by the time the prefetch reaches its post-await body, it has already cleared the entry-gate that reads `_loadingOlder`, so a same-flag check inside the resolved callback is a no-op. The actual fix is a generation-token + mutex pair: (1) `_loadOlderMessages` snapshots a new module-scoped `_messagesGeneration` counter BEFORE its `await api(...)` and re-checks it after, aborting the prepend if any wholesale-replace bumped the token mid-flight; (2) `_ensureAllMessagesLoaded` claims the `_loadingOlder` mutex around its body (so a NEW prefetch cannot start mid-replace, and concurrent ensure-all calls from rapid double-clicks on Start serialize cleanly), bumps the generation token before mutating `S.messages`, yields until any in-flight prefetch's `finally`-block releases the mutex, and resets `_oldestIdx` so a subsequent prefetch cannot send a stale `msg_before` index. Also adds the same-session and `_loadingSessionId` guards that the original ensure-all body was missing post-await. (`static/sessions.js`, `tests/test_issue1937_endless_scroll_jumpstart_race.py` — 12 new regression tests)
+- **PR #1945** by @franksong2702 — Localized the six session-jump-button keys (Start/End labels, aria labels, Appearance setting copy) for ja/ru/es/de/zh/zh-Hant/pt/ko. The opt-in `session_jump_buttons` setting in #1928 (Release G) had English fallbacks in non-English locale blocks; this completes the parity. Strengthened the regression test so future changes cannot leave English literals in non-English locales. Closes #1938.
+
+- **PR #1947** by @happy5318 — Show the same model from different named custom providers in the dropdown instead of silently dropping the second provider's entry. The `_seen_custom_ids` global bucket in `get_available_models()` was seeded from `auto_detected_models` and used a bare model id as the dedup key, so a second named provider exposing the same model id (e.g. both `baidu` and `huoshan` exposing `glm-5.1`) had its entry dropped. Switched the dedup key to `f"{slug}:{model_id}"` so each provider's models track independently. Maintainer-augmented with a regression test (`test_pr1947_same_model_multiple_custom_providers.py`) that fails on master and passes on the fix. Co-authored by @hacker1e7 (independently filed #1874 with broader scope; closed in favor of the narrower fix).

+- **PR #1949** by @Sanjays2402 — Closes the v0.51.30 regression race between endless-scroll prefetch and Start-jump's `_ensureAllMessagesLoaded` (Issue #1937). With both opt-ins ON, an in-flight `_loadOlderMessages` racing with `jumpToSessionStart → _ensureAllMessagesLoaded` could prepend a duplicate page if the prefetch resolved last. The naive same-flag-check approach (proposed in #1942 and #1962, both closed in favor of this PR) is a no-op for the post-await race because the prefetch has already cleared the entry-gate. The actual fix is a generation-token + mutex pair: (1) `_loadOlderMessages` snapshots a module-scoped `_messagesGeneration` counter before its `await api(...)` and re-checks it after, aborting the prepend cleanly if any wholesale-replace bumped the token mid-flight; (2) `_ensureAllMessagesLoaded` claims the `_loadingOlder` mutex, bumps the generation token before mutating `S.messages`, yields until any in-flight prefetch's `finally` releases the mutex, then claims the mutex itself. Also adds same-session and `_loadingSessionId` guards that the original ensure-all body was missing post-await. 12 new regression tests pin the wait → lock → fetch → mutate → unlock invariant. Co-authored by @franksong2702 and @Michaelyklam (parallel-discovery PRs). Closes #1937.
+
+- **PR #1950** by @franksong2702 — Mute stale stopped gateway heartbeat. When the root `gateway_state.json` had `gateway_state == "stopped"` and was older than the freshness threshold, the existing logic still treated it as a configured-but-down gateway, surfacing a persistent heartbeat-down alert for users running only profile-scoped gateways. New stale-stopped helper in `api/agent_health.py` reports `alive: null` with reason `gateway_stale_stopped_state` instead of `alive: false`. Fresh stopped states still report down (so a recently stopped configured root gateway continues to surface as an outage), and stale `gateway_state == "running"` still reports down (preserving the #1879 false-positive guard). Closes #1944.
+
+- **PR #1951** by @amlyczz — Gate the goal evaluation hook on goal-related turns only (Issue #1932). Pre-fix, `evaluate_goal_after_turn()` fired on every completed assistant turn when a goal was active, including unrelated user messages — burning the goal budget, triggering continuation prompts that interrupted unrelated conversations, and making `/goal status` numbers misleading. Added `STREAM_GOAL_RELATED` (dict) + `PENDING_GOAL_CONTINUATION` (set) flags in `api.config`; `_run_agent_streaming` accepts a `goal_related=False` kwarg and skips the goal evaluation section when not goal-related; `goal_continue` adds the session to `PENDING_GOAL_CONTINUATION` so the next stream is auto-marked; routes propagate the flag and the `/api/goal` kickoff path passes `goal_related=True`. Co-authored by @franksong2702 (parallel #1946 closed in favor of this PR's broader test coverage). Closes #1932. Stage-326 hotfix per Opus advisor: removed `PENDING_GOAL_CONTINUATION.discard(session_id)` from the streaming worker's `finally` block — that race-erased the marker before the consumer in `routes.py` could read it; the consumer already discards atomically on read. 5 new regression guards pin the corrected ordering.
+
+- **PR #1953** by @lucky-yonug — Skip the `#1776` provider-peel for custom host:port slugs. `model_with_provider_context` can emit `@custom:::` when the model provider is derived from an OpenAI `base_url` authority (e.g. `custom:10.8.0.1:8080`). The existing colon-count heuristic mistook those extra colons for an over-split model id and prepended the port segment onto the bare model (`8080:Qwen3-235B`), breaking WebUI while CLI/curl stayed correct. Now detects endpoint-style slugs (IPv4 / localhost / dotted-hostname + numeric port) and skips the peel in that case. References #1776.
+
+- **PR #1960** by @Michaelyklam — Translate the `workspace_show_hidden_files` label for ja/ru/es/de/zh/zh-Hant/pt/ko, replacing the English fallbacks in seven non-English locales. Closes #1841.
+
+- **PR #1961** by @sbe27 — WebUI now respects `image_input_mode` instead of unconditionally embedding native `image_url` parts. `_build_native_multimodal_message()` was bypassing the agent's `image_input_mode` config, causing silent turn failures with non-vision models or text-only fallbacks. Added `_resolve_image_input_mode(cfg)` mirroring `decide_image_input_mode()` and wired into the multimodal message builder; when mode resolves to `"text"`, returns a plain string so `vision_analyze` handles images instead. Closes #1959.
+
+### Cluster-resolution decisions
+
+Three duplicate-PR clusters consolidated to one canonical PR each, with `Co-authored-by` attribution preserved on the merge commit:
+
+- **#1937 race** — three competing fixes filed within 24h: #1942 (synchronous mutex), #1949 (generation-token + mutex), #1962 (serialization + browser evidence). Selected #1949 as the canonical fix; the synchronous-mutex approach in #1942/#1962 doesn't reach into a prefetch's resolved callback once it's past the entry-gate. Browser evidence under `docs/pr-media/1937/` was not absorbed (the fix in stage covers what the evidence demonstrates).
+
+- **#1932 goal hook** — same-shape fixes in #1946 and #1951. Selected #1951 for the materially better test coverage (10 dedicated regression tests vs handful in #1946); both PRs ship the `goal_related` flag through `/api/chat/start` → streaming worker.
+
+- **Custom-provider dedup** — #1874 (broad scope including a behavior change to `_deduplicate_model_ids`) vs #1947 (4-LOC minimum-correct fix). Selected #1947; #1874's `_deduplicate_model_ids` change can be revisited as a separate PR if the underlying gap is real.
+
+### Stage-326 fixes applied per Opus advisor
+
+- **CRITICAL #1951 PENDING_GOAL_CONTINUATION race fix.** The original PR's `finally`-block discard at `api/streaming.py:3553` race-erased the marker before the frontend's SSE-receive → `POST /api/chat/start` round-trip could consume it. Removed the discard; the consumer in `routes.py` discards atomically on read. 5 new regression guards in `tests/test_stage326_pending_goal_continuation_race.py` pin the corrected ordering.
+
+- **#1956 composer-draft input validation.** Added size + type clamps (text 50 KB max str-coerce, files 50 entries max list-coerce) to the `POST /api/session/draft` handler. Without this, a misbehaving client could persist multi-MB strings into the session JSON via the 400 ms debounced auto-save. 5 new validation tests in `tests/test_stage326_composer_draft_validation.py`.
+
+- **#1957 SESSION_TTL constant preserved.** The original PR deleted the `SESSION_TTL = 86400 * 30` module constant; existing regression tests (`test_v050258_opus_followups::test_redirect_session_ttl_30_days`, `test_auth_sessions::test_session_ttl_is_24_hours`) pin it as a guard against the daily-kick-out regression from #1419. Restored as the named fallback for `_resolve_session_ttl()`. Reconciled the new `TestSessionTtlResolution` class to use unittest setUp/tearDown env snapshotting rather than the pytest `monkeypatch` fixture (incompatible with `unittest.TestCase` subclasses) and aligned clamp tests with the actual fall-through-to-default behavior.
+
+### Tests
+
+5006 → **5028 collected, 5028 passing, 0 regressions** (+51 net new across the 12 PRs + 10 stage-326 hardening tests). Full suite ~143 s on Python 3.11 (HERMES_HOME isolated). JS syntax check (`node -c`) clean on all 5 modified `static/*.js` files. Browser API sanity harness (port 8789): all 11 endpoints + 20 QA tests PASS. Manual live verification on stage-326 server (port 8789): composer-draft validation working (50 KB clamp, 50-entry files clamp, type coercion); session TTL resolution honors env var (3600 s) and falls through on out-of-range. Opus advisor: SHIP-WITH-FIXES (all required + recommended fixes applied in `404e24ac` + `8782fd26` stage commits).
