Record resolved_model on assistant messages as _usedModel, expose used_model
in the usage SSE payload, and render model chips in transparent and settled
turn footers while suppressing duplicates when gateway routing already shows
used_model.
The suite failed 6 tests (test_sprint12 default-model, test_issue1538 Nous
catalog, test_issue1567 picker capacity/symmetry) whenever it ran on a box that
exports HERMES_MODEL (e.g. inside a live Hermes agent session where HERMES_MODEL
is the agent's runtime model). Root cause: get_effective_default_model() in
api/config.py treats HERMES_MODEL / OPENAI_MODEL / LLM_MODEL as the
highest-priority default-model source — above the isolated test config — so a
runner-exported value overrode the sandbox config and polluted the model
picker/catalog (e.g. injecting "opus-4.8" and breaking the @nous: prefix
invariant / default-model readback).
Fix: scrub the three model-selection env vars at conftest module level (before
any product module imports, covering in-process tests) and again in the
out-of-process test_server subprocess env, and add them to the per-test
_scrub_provider_env helpers in the two Nous test modules. The isolated config /
HERMES_WEBUI_DEFAULT_MODEL is now authoritative regardless of the runner env.
Verified: with HERMES_MODEL=opus-4.8 set, the full suite goes from 6 failed to
0 failed (13550 passed); non-vacuity confirmed (disabling the scrub reproduces
the failures).

* feat(extensions): token-v1 proxy->sidecar auth boundary
Mint a per-extension secret core injects (X-Hermes-Sidecar-Token) on every
proxied request; sidecars validate it. Closes the hole where a loopback sidecar
port is reachable by any local process and cannot distinguish a proxied request
from a direct one.
- api/extension_sidecar_auth.py: per-extension token lifecycle (atomic mint,
re-read-verified so an unpersisted token is never injected, per-request
mtime-cached read for live rotation, path-escape-safe)
- manifest proxy_auth negotiation: absent=legacy, token-v1=enforce, unknown=fail-closed
- proxy: inject token, strip inbound + response x-hermes-*, auth-off posture
(loopback-only local_unprotected, else 503), fail-closed when token unavailable
- consent-time auth_required in status payload; mint-on-consent
- docs/EXTENSIONS.md proxy_auth section
- 7 new tests (26/26 green)
* fix(extensions): address Codex+Fable gate on token-v1 (6 findings)
- align token-module extension-id grammar with core _EXTENSION_ID_RE (was
narrower -> legally-named ext consented then 503'd forever)
- resolve token dir dynamically (mirror _extension_state_dir) -> real test
isolation, no import-time STATE_DIR cache
- cross-process mint: O_CREAT|O_EXCL no-clobber claim (was os.replace clobber)
- rotation cache keyed on full fingerprint (ino/dev/mtime/ctime/size) +
re-fingerprint after read -> same-size/mtime replacement no longer stale
- validate token format on read (url-safe, 16-256) -> malformed file can't
leak via a ValueError echoed in a 502
- consent fails 503 when token can't be provisioned (was silent-swallow ->
persisted consent then 503 forever)
- rename status auth_required -> posture enum (protected|local_unprotected):
nothing is blocked for loopback, so 'required' was misleading
- panels.js: render local_unprotected warning on the consent row (+ CSS)
- docs: token-path resolution order, 401-vs-503, explicit 'legacy' acceptance
- tests: route-level token-injection+response-strip test; fix illusory isolation
in token-module test; 27/27 green
* fix(extensions): close 2 token-mint races (Codex re-gate round 2)
- mint via temp-file + atomic os.replace (not O_CREAT|O_EXCL) so the final
path is never observed empty/half-written — a concurrent loser can no longer
read an empty token file and 503
- single _stable_read helper (fingerprint-read-refingerprint, bounded retry on
mid-read change) used by BOTH ensure_token and current_token — a token that
changes during the read is never returned or cached stale
- stress-verified: 20 concurrent first-mints converge on 1 persisted token; 27/27
* fix(extensions): atomic no-clobber token publish via os.link (Codex re-gate round 3)
os.replace fixed empty-file exposure but still clobbered cross-process: two
processes could both write+replace and a reader between them got a token no
longer on disk -> 401. Switch to the repo's TOCTOU-safe os.link create-or-fail
idiom (session_recovery.py:627): write temp -> link into place (fails if a
winner already published) -> loser drops its temp and reads the winner via
_stable_read. Proven: 16 concurrent PROCESSES converge on 1 persisted token,
all matching disk. 27/27 tests green.
* fix(extensions): resolve Frank+Greptile #6331 review — token-v1 fail-closed when auth off (consent+resolution), token-v1-only proxy_auth/posture status fields, fullmatch ext-id validator
* fix(extensions): finish Frank and Greptile sidecar review

* fix(webui): keep the content search from evicting the user's working set
/api/sessions/search?content=1 walks EVERY session and pulls each one through
get_session(), which inserts it into the SESSIONS LRU and marks it
recently-used. On any install with more sessions than sessions_cache_max
(default 300), a single search therefore flushes the whole cache and refills it
with sessions the user is not looking at — the classic buffer-pool
scan-pollution problem. The sessions actually open in the UI are exactly the
ones evicted, and the search is keystroke-debounced, so it repeats while typing.
A scan reads each session exactly once, so nothing it touches has earned
"recently used". get_session_for_scan() reuses a resident session without
promoting it, and reads a cold one straight from disk without caching it. It
returns None rather than raising, since a scan skips what it cannot open.
This is a correctness fix for cache behaviour, not a latency fix. The
multi-second searches that led here were contention, not scan cost: a trivial
/api/profiles took 9.2s in the same window, and a full read+parse of ~1700 real
sessions measures ~4s total.
test_sessions_search_depth_validation patched api.routes.get_session. With the
search reading through the scan accessor it now patches get_session_for_scan —
left unfixed, two of its cases fail and the third passes vacuously against an
empty result set.
Validation:
pytest tests/test_issue4765_sessions_lru_eviction.py
tests/test_sessions_search_depth_validation.py -> 13 passed
Both added eviction tests fail on the pre-fix accessor (verified by revert):
the working set drops from 4/4 to 0/4 resident after one scan.

* feat(terminal): broadcast output to every viewer instead of one shared queue
TerminalSession.output was a single queue.Queue read destructively by the SSE
handler. Two tabs/windows viewing the SAME session each open their own
EventSource, so two _handle_terminal_output handlers competed on that one queue:
every PTY chunk was delivered to exactly one of them. Each tab saw a disjoint
half of the byte stream, and only one ever received terminal_closed.
Output now fans out, mirroring StreamChannel/SessionChannel: each SSE consumer
subscribe()s its own queue (seeded with a bounded backlog so a first/late attach
still replays the recent scrollback, preserving the old buffer-until-first-
consumer behaviour), and put_output broadcasts to all subscribers. A slow
viewer's queue drops its own oldest chunk (drop-oldest, isolated per subscriber)
so one lagging tab can't starve another. The handler unsubscribes in a finally
so the subscriber list can't grow.
Stacked on the terminal fd-leak fix (same file).

Add an opt-in setting to hide Transparent Stream's per-event timestamp chips while keeping the response footer time visible, for users who found the per-event chips noisy. Thanks @rodboev. Closes#6099.
Recover checkpointed core background processes and rebuild PROCESS_SESSION_INDEX on WebUI startup, so an ordinary terminal(background=True, notify_on_complete=True) proc_* completion that outlives a WebUI restart can still wake its original session.

allow_values: [""] would brick an OIDC-only deployment (every callback 403s).

* fix(reasoning): gate reasoning_effort ladder to GLM-5.2+ on native zai
Z.AI's API (docs.z.ai) defines reasoning_effort as GLM-5.2+ exclusive, but
hemes-webui advertised the full 6-level ladder for all 7 GLM models because
_candidate_supports_reasoning has an unconditional glm token match and
_filter_reasoning_efforts_for_provider had no ZAI branch. Six of seven catalog
models (glm-5.1, glm-5, glm-5-turbo, glm-4.7, glm-4.5, glm-4.5-flash) showed a
selector whose values the endpoint silently ignores, and GLM-4.7 (forced thinking
that cannot be disabled per Z.AI docs) showed a 'none' option with no effect.
Add a ZAI branch to _filter_reasoning_efforts_for_provider mirroring the existing
OpenAI/Gemini/Anthropic ceiling pattern: strip the whole ladder for pre-5.2 GLM
models and for the forced-thinking GLM-4.7 family; preserve the full ladder for
GLM-5.2+ (whose accepted values match VALID_REASONING_EFFORTS exactly). The gate
is scoped to the native zai provider only (aliases glm/z-ai/z.ai/zhipu all
resolve to zai); aggregator providers are untouched because they route through
their own routers, not Z.AI's native endpoint.
The glm family-detection heuristic in _candidate_supports_reasoning is unchanged
— GLM models DO support the thinking on/off toggle at the family level; this fix
is specifically about the reasoning_effort intensity ladder.
State layer: agent.reasoning_effort config + UI dropdown options derived from
resolve_model_reasoning_efforts. Invariant: UI options and coercion now agree
and match Z.AI's per-model docs (max offered only for GLM-5.2+, none never
offered for forced-thinking models). Out of scope: the thinking:{type:...}
request-field translation lives in the external agent/gateway layer.
* fix(reasoning): close ZAI coercion gap + harden test assertions
Address Greptile review on #6219 (round 1):
1. Vacuous test assertion (test_glm_5_2_preserves_none_sentinel): the 'or'
fallback made the assertion always-true, so a regression stripping 'none'
for GLM-5.2 would go undetected. Rewrote to inject 'none' via the raw source
(mocking _resolve_model_reasoning_efforts_impl) and assert it survives — the
test now genuinely exercises the preservation branch.
2. Coercion gap for non-max stored levels on pre-5.2 GLM: the existing
'if ceiling and raw not in ceiling' guard treats an empty ceiling as 'no
rule' (preserving the configured effort verbatim per #3505), so a stored
'high'/'medium'/'low' for glm-5.1/glm-4.5/glm-4.7 on native zai was forwarded
to Z.AI unchanged and silently ignored — contradicting the PR's stated
UI/coercion agreement invariant.
Root cause: the ZAI gate returns [] to mean 'known-empty' (no
reasoning_effort at all), but the coercion path treated all [] as
'ambiguous/unknown, preserve verbatim'. Fixed by extracting the ZAI decision
into _zai_glm_reasoning_efforts_supported (True/False/None sentinel) shared by
both the filter and coercion, then special-casing the known-False result in
coerce_reasoning_effort_for_model to return '' (send no field). The #3505
preserve-verbatim behavior for genuinely-unknown models on non-zai providers
is unchanged.
Added 10 regression tests (all fail before the coercion fix, pass after):
- All 6 levels (max..minimal) coerce to '' for each pre-5.2 GLM + glm-4.7
- All 4 aliases (glm/z-ai/z.ai/zhipu) resolve through the same coercion gate
- GLM-5.2 preserves all 6 levels verbatim
- Regression guard: unknown model on custom: provider STILL preserves verbatim
State layer: agent.reasoning_effort config + the value forwarded to Z.AI.
Invariant now fully holds: UI offers no options for pre-5.2 GLM AND coercion
sends no reasoning_effort field for any stored level on those models.
* fix(reasoning): preserve ZAI GLM 4.5-5.1 thinking toggle when effort ladder empty
Address nesquena-hermes round-2 review on #6219: returning [] for the effort
ladder on sub-5.2 GLM models hid the entire reasoning chip in the composer
(static/ui.js:4932 treats empty supported_efforts as 'no reasoning control at
all'), silently regressing the working thinking on/off toggle for GLM-4.5/4.6/
5.0/5.1 users. Per Z.AI's own docs, those models accept the thinking
{type:enabled|disabled} toggle even though they do not accept the
reasoning_effort intensity ladder.
Fix decouples thinking-toggle capability from the effort ladder:
Backend (api/config.py):
- Refactor _zai_glm_classification returns one of 'effort' (GLM-5.2+), 'thinking'
(GLM-4.5 up to but not including 5.2), 'forced' (GLM-4.7 family), or None
(non-zai / non-GLM). Single source of truth shared by all three consumers.
- _zai_glm_reasoning_efforts_supported now wraps classification for the coercion
contract (unchanged behavior).
- _zai_glm_thinking_toggle_supported returns True for 'effort' or 'thinking',
False for 'forced', None otherwise.
- get_reasoning_status gains a supports_thinking_toggle field = bool(supported)
OR (zai_thinking is True). Non-zai providers default to bool(supported_efforts)
so their chip-visibility behavior is unchanged.
Frontend (static/ui.js):
- New _currentReasoningToggleSupported state var (default undefined = treat as
true so legacy responses without the field do not newly hide the chip).
- _applyReasoningChip shows the chip when hasEffortLadder OR toggleSupported.
Empty efforts + toggle=True keeps the chip visible with just the None/On
control (the existing _applyReasoningOptions already shows 'none' when the
ladder is empty). Empty efforts + toggle=False (GLM-4.7 forced) hides it.
- Profile-transition and fetch-failure resets now pass
supports_thinking_toggle:false alongside the empty efforts so the chip hides
during the unknown-state window, matching the prior reset contract.
Tests (30 new):
- _zai_glm_classification parametrized across all three tiers + aliases + defer
- get_reasoning_status supports_thinking_toggle per tier (GLM-5.2 both, GLM-4.6
toggle-only, GLM-4.7 neither, non-zai defaults to effort capability)
- Frontend _applyReasoningChip behavior via node driver: empty efforts +
toggle=True stays visible, toggle=False hides, effort ladder alone is
sufficient, absent field keeps prior behavior
State layer: agent.reasoning_effort config + supports_thinking_toggle field in
/api/reasoning + composer chip visibility. Invariant: the chip is hidden ONLY
when the model supports neither the effort ladder nor the thinking toggle
(GLM-4.7 forced, or genuinely non-reasoning models); GLM-4.5-5.1 retain the
working On/None control they had before the round-1 effort gate.
* fix(reasoning): make ZAI thinking toggle two-way + force GLM-4.7 stored none
Address nesquena-hermes round-3 review on #6219 — two SILENT gaps in the
thinking-toggle path, plus a click-handler sibling I found while auditing.
Gap #1 — ONE-WAY toggle for GLM-4.5/4.6/5.0/5.1 (api/config.py:4247,
static/ui.js:4902, static/index.html:757):
The round-2 fix kept the chip visible for thinking-tier models but the only
rendered dropdown option was 'None' (the HTML had no Default option, and
set_reasoning_effort rejected empty effort with 400). So a GLM-4.6 user could
turn thinking OFF but never back ON — worse than the original bug.
Fix:
- set_reasoning_effort now accepts empty effort as 'clear the override' (removes
agent.reasoning_effort so the provider default takes effect). Invalid values
still raise ValueError.
- static/index.html gains a <div data-effort=''>Default</div> option.
- _applyReasoningOptions always shows both Default ('') and None alongside the
effort ladder, so a thinking-tier model (empty ladder + toggle=true) renders
an operable Default+None two-state control.
- Click handler (ui.js:5106) checks option presence (if(opt)) not truthiness
(if(effort)) — the old check silently ignored data-effort='' clicks, which
would have left the Default button dead even after the HTML/backend changes.
Gap #2 — GLM-4.7 not forced when 'none' stored (api/config.py:3984, :3857):
When GLM-4.7 had agent.reasoning_effort=none configured, coercion preserved
'none' via the early return at line 3985, so streaming built disabled reasoning
for a model that forces thinking on regardless. Separately, when the raw
capability source listed 'none', resolve_model_reasoning_efforts reattached it
to GLM-4.7's supported_efforts (['none']), leaking an 'off' option to the UI
for a forced-thinking model.
Fix:
- coerce_reasoning_effort_for_model checks _zai_glm_classification == 'forced'
BEFORE the generic 'none' early-return, coercing stored 'none' to '' (default
= thinking on) for forced models.
- resolve_model_reasoning_efforts returns [] early for forced-tier models,
skipping the 'none' reattachment entirely.
Tests (17 new):
- Gap #2: coerce('none', glm-4.7) -> '', regression guard that non-forced GLM
still accepts 'none'; resolve does not reattach 'none' for forced but DOES
for thinking-tier; end-to-end get_reasoning_status for forced+stored-none.
- Gap #1 backend: set('') clears the key (no raise), set('garbage') still
raises, all 7 valid levels still save.
- Gap #1 frontend: three new node-driver tests asserting the dropdown exposes
both Default and None for thinking-tier (two-state), Default+None+ladder for
effort-tier, and the off->on->off round trip keeps both visible throughout.
- Updated test_reasoning_show_hide.test_set_reasoning_effort_rejects_invalid to
reflect the new contract (empty accepted, garbage rejected).
Regression gate: gap#2 coerce tests fail without the forced-tier check (3
failures); gap#1 backend test fails with 'ValueError: effort is required'
without the empty-acceptance change. 219 passed, 1 pre-existing skip across
the full reasoning + chip + config-cache surface.
State layer: agent.reasoning_effort config + supports_thinking_toggle field +
composer dropdown options. Invariant: the thinking toggle is now genuinely
two-way for GLM-4.5-5.1 (Default=on, None=off, both always visible) and
GLM-4.7 forced-thinking never offers 'none' in any path (coerce, resolve,
status, or UI).

* feat(core): add registerHermesSessionOpenHandler + renderTranscript extension hooks
- registerHermesSessionOpenHandler(fn): register a handler that fires on
session open. Return {cancel:true} to prevent navigation.
- renderTranscript(container, messages, opts): render messages into any
DOM container using core's renderMd pipeline. Skip tool messages.
- Wire _hermesNotifySessionOpen into loadSession: pre-load guard at top,
post-load notification at end for extensions to hook into.
- Follows existing registerHermesTtsEngine extension registration pattern.
This gives extensions like chat-tiling a sanctioned API instead of DOM
hacking to intercept and render session transcripts.
* fix: address 3 gate-fail blockers from PR #5508 review
Fixes the three core issues identified by nesquena-hermes code review:
1. XSS sink in renderTranscript (boot.js)
- Fallback to textContent when window.renderMd is unavailable
- innerHTML exclusively for successful renderMd output
2. Stale _loadingSessionId reset in cancel branch (sessions.js)
- Remove premature nulling of _loadingSessionId
- Cancel path simply returns without touching loading-guard state
3. Pre-open veto bypasses profile/import side-effects (sessions.js)
- Move cancellable preload hook to start of _openSidebarSession,
before external session import and profile switching
- Pass internal _preloadNotified flag to skip duplicate preload
in loadSession while retaining post-load notification
Closes#5508 gate-fail items.
* fix: use module-level flag instead of call argument to avoid test regression
The _preloadNotified approach broke test_static_sessions_js_switches_profile
before_opening_all_profiles_row because it changed the loadSession call
signature from loadSession(sid, loadOpts) to loadSession(sid, Object.assign(...)).
Switch to a module-scoped boolean _hermesSessionOpenAlreadyFired set by
_openSidebarSession before calling loadSession, checked by loadSession's
pre-hook guard. The call signature stays unchanged.
Test 2 (test_load_session_rearms_stream_on_every_early_return) also passes.
* fix: compact pre-hook comment to keep loadSession within test window limits
* fix: replace global _hermesSessionOpenAlreadyFired flag with per-call opts._preloadNotified
The module-level boolean introduced in 381fa0ef had two problems:
1. ReferenceError on direct loadSession() calls — the flag was undeclared
when called outside _openSidebarSession, breaking saved-session restore.
2. Never reset after first sidebar open — all subsequent direct calls
silently skipped the cancellable preload handler.
Per the maintainer's review (PR #5508), replace the global with a per-call
option _preloadNotified passed by _openSidebarSession via Object.assign.
This keeps the call signature stable for existing tests and eliminates
the stale global state leak.
Test adjustments:
- test_issue1611: widened loadSession call literal assertion
- test_session_channel_option_x: body slice 14000→15000 to accommodate
the slightly longer function body

3. Add functional test_extension_session_hooks.py — actually drives the
new hook registration, preload-veto, transcript rendering, and
_preloadNotified bridge in Node (13 tests, all green).
* Remove unused pytest import
Removed unused import of pytest from test file.
* fix: address 2 gate-blocking veto-ordering defects (PR #5508)
Blocker 1 (CORE): cross-profile retry now passes _preloadNotified:true
so the pre-hook doesn't re-fire after destructive side-effects already
ran (stream teardown, message clear, profile switch). A {cancel:true}
on that second fire was stranding the UI profile-switched with a
cleared transcript.
Blocker 2 (SILENT): closeMobileSidebar() was called synchronously
BEFORE _openSidebarSession()'s veto guard in three places (tap-to-open,
child-session, lineage-segment). A {cancel:true} still closed the
sidebar out from under it. Removed the three premature calls; moved
a single closeMobileSidebar() inside _openSidebarSession AFTER the
veto guard so it only runs when the open actually proceeds.
Added 3 regression tests asserting {cancel:true} leaves NO side-effect.
* CHANGELOG: extension session-open handler + renderTranscript API (#5508)

* fix(transparent-stream): drop stale final-answer prefix row in multi-segment settle (#5749 follow-up)
A turn with interim assistant messages (prose interleaved with tool calls)
could show the beginning of the final answer TWICE after watching it stream:
once as a settled anchor-scene prose row (the live-token accumulator's last
throttled snapshot) and once as the real assistant segment. The duplicate
persisted until reload.
Root cause: #5758 suppresses the accumulator row only when it sits "after the
last tool row", but _completeSettledAnchorSceneForTurn appends the settled
per-message tool rows AFTER the projected live rows — those re-list tools that
ran EARLIER in the turn, pushing the boundary past the final segment's
accumulator so the guard never fired. The stale prefix snapshot then survived
into the persisted scene and rendered above the settled answer.
Fix: judge final-segment eligibility against the LIVE projection's own
chronology — a live-prose row belongs to the final segment iff no PROJECTED
tool row follows it. Pre-tool narration that happens to prefix the final
answer stays protected (existing #5758 regression tests still pass), and a
new regression test pins the multi-segment shape.
Verified end-to-end by replaying the captured run journal of an affected
session through the real SSE live handlers in headless Chromium: duplicate
before (answer prefix visible twice after settle), gone after; fresh-reload
rendering unchanged.
Rollback: revert this commit; behavior returns to pre-fix (duplicate prefix
row after live-settle of multi-segment turns).

* feat: expose msg_limit ceiling via /api/session metadata, frontend reads dynamically (#6177)
Backend exposes _MAX_MSG_LIMIT as _msg_limit_max in every /api/session
response. Frontend reads it dynamically, falling back to _MSG_LIMIT_MAX
for older servers. This removes the hand-mirrored coupling between the
two layers.
Removed test_msg_limit_ceiling_drift.py since the mirror pattern that
required the drift guard is replaced by dynamic metadata.
This is the standalone metadata-decoupling piece from #6206,
without the clamp/paging that already shipped in exp-v0.52.98 via #6152/#6154.
* fix(session): declare _msgLimitMax at module scope + CHANGELOG + gate fixes (#6214 follow-up)
The submitted PR used _msgLimitMax at two read sites (boundedReloadLimit in
_ensureMessagesLoaded, useBeforePaging in _loadOlderMessages) but never declared
it and read it before assignment -> undefined on cold load -> full-transcript
fetch every load (regression) + implicit global. Declared `let _msgLimitMax =
_MSG_LIMIT_MAX;` at module scope so the reload-width paths always read a defined
value (the static fallback) until the server's _msg_limit_max lands.
Also: defined the ceiling globals in the two inline node-harness tests that copy
_ensureMessagesLoaded's body (test_cross_session_message_load_isolation,
test_session_unread_dot_on_visit), updated the source-string assertion in
test_webui_external_refresh_frontend, and added 3 decoupling tests (backend field
present, module-scope declaration + fallback, both paths read the live ceiling)
replacing the deleted drift-guard.
Gate: Codex adversarial SAFE TO SHIP (executable probes: cold-load fallback,
mixed-version omission, live update, cross-session isolation, over-ceiling bare
refresh, msg_before row preservation). Full sharded suite green.

* fix(routes): clamp GET /api/session msg_limit to a server-side ceiling
Memory: ?msg_limit= had no upper bound — a client could request
msg_limit=1000000 (or the frontend's msg_limit=9999 outline-jump path) and
force the server to assemble and serialize an unbounded message payload. The
frontend's real pagination grows windows by ~30 at a time (initial load 30,
load-older +30, msg_before paging 30), so only the outline-jump and
pathological/hostile cases ask for huge values.
Add _MAX_MSG_LIMIT (500) and clamp at the query-parse site
(max(1, min(int(_msg_limit), _MAX_MSG_LIMIT))). The ceiling is generous — far
above any legitimate visible-row window — so real pagination is unaffected. The
existing _messages_truncated signal already covers the clamped case: when the
request exceeds the ceiling, _message_window_for_display returns
_messages_offset > 0 and the client learns more rows exist (load-older still
works). The bare no-msg_limit path is intentionally unchanged — it is the
documented "give me everything" escape hatch used by branch/undo/jump-to-start
flows that need the full transcript for correct global indices.
Test: tests/test_session_msg_limit_ceiling.py — the ceiling constant is
reasonable (100..2000), an over-ceiling request is clamped and signals
truncation, and legit sizes (5/30/60/100) are unaltered. Existing window/tail
tests (19) unchanged.
Contract Routing
- Task type: memory-bound fix (unbounded msg_limit request payload).
- Touched areas: GET /api/session query parsing (api/routes.py).
- Relevant public docs: AGENTS.md, CONTRIBUTING.md, docs/CONTRACTS.md.
- State layer mutated: none (read-only endpoint response shaping).
- Contract change (additive): ?msg_limit=N is now clamped to _MAX_MSG_LIMIT=500.
Compatibility: the only frontend caller above the ceiling is outline.js's
msg_limit=9999, which now receives up to 500 rows + _messages_truncated=true
(load-older still works). All other callers (30/60) are unaffected. The bare
no-msg_limit path is unchanged.
Release note: GET /api/session now caps ?msg_limit at 500 rows server-side,
bounding the worst-case payload for oversized requests.
Model Used: builtin:zai-coding-plan/GLM-5.2 (ZCode agent).
* fix(frontend): route msg_limit-heavy paths around the server ceiling
PR #6152 clamps GET /api/session ?msg_limit= to a max of 500 server-side. Two
frontend paths relied on unbounded msg_limit and silently broke for sessions
> 500 visible rows:
1. outline.js _jumpToMessage sent msg_limit=9999 as a "give me everything" hack
so it could scroll to any message by absolute index (msg-user-<rawIdx>).
Clamped to 500, the target row's DOM id doesn't exist for early messages in
long sessions, and the jump silently no-ops (line 119 `if (r)` is falsy).
Fix: drop msg_limit=9999 — use the bare messages=1 path, which #6152 left
unbounded precisely for callers that need the full transcript. This restores
exact pre-#6152 behavior for outline jumps.
2. sessions.js _loadOlderMessages grows msg_limit by +_INITIAL_MSG_LIMIT each
load (30 -> 60 -> ... -> 500 -> clamped). Past 500 the server returns the
same clamped tail, olderMsgs shrinks to 0, and endless-scroll / "Load
earlier" silently stalls — the head becomes unreachable. Fix: once the grown
requestedLimit meets/exceeds the new _MSG_LIMIT_MAX mirror (500), switch the
primary fetch to msg_before paging (a fixed _INITIAL_MSG_LIMIT backward page
keyed off _oldestIdx) — the same bounded paging the existing race-fallback
uses, so the head stays reachable for arbitrarily long transcripts. The
response is handled by the existing prepend path (tailMatches is naturally
false for a page, so the !tailMatches branch reuses the fetched data).
Added _MSG_LIMIT_MAX = 500 constant in sessions.js mirroring backend
_MAX_MSG_LIMIT, documented as kept-in-sync.
Verification: node --check passes on both files; the backend window-contract
tests (test_session_tail_payload, test_session_message_window_renderable_tail,
19 tests) still pass. No JS test harness exists in this repo (vanilla JS,
manual browser verification per TESTING.md) — manual verification needed: open a
> 500-message session, (a) click an outline entry for an early message and
confirm it scrolls+flashes, (b) scroll up past 500 loaded rows and confirm
"Load earlier" keeps producing older messages without stalling.
Contract Routing
- Task type: frontend follow-up to a backend memory fix (#6152).
- Touched areas: outline jump-to-message (static/outline.js), endless-scroll /
load-older (static/sessions.js _loadOlderMessages).
- Relevant public docs: AGENTS.md, CONTRIBUTING.md, docs/CONTRACTS.md.
- State layer mutated: client-side S.messages (the active-session transcript),
same as the existing load-older path. No backend state change.
- Scope boundaries: does not weaken the #6152 clamp. The bare messages=1 path
(outline) was intentionally left unbounded by #6152; the msg_before paging
path (load-older) is bounded by _INITIAL_MSG_LIMIT and never hits the ceiling.
Release note: fixes outline jump-to-message and endless scroll silently
breaking on sessions longer than 500 messages after the server-side msg_limit
ceiling (companion to #6152).
Model Used: builtin:zai-coding-plan/GLM-5.2 (ZCode agent).
* test(frontend): update static-source assertion for refactored _loadOlderMessages fetch
The static-source test test_session_message_loads_keep_explicit_longer_timeouts
asserted the exact multi-line shape of the _loadOlderMessages fetch strings.
The #6154 refactor wrapped them in a useBeforePaging ternary (tail-growth vs
msg_before paging), reindenting them — the contract the test guards (both
fetches keep timeoutMs:120000 for large state.db loads) is preserved, but the
literal source shape changed, so the assertion failed on shard 0.
Updated the assertions to match the new source shape while keeping the test's
intent: assert each fetch URL + its {timeoutMs:120000} survive in sessions.js.
Model Used: builtin:zai-coding-plan/GLM-5.2 (ZCode agent).
* test(msg-limit): stopgap drift guard for _MSG_LIMIT_MAX === _MAX_MSG_LIMIT
Reviewer guidance (#6154 round-2): the stopgap drift-test belongs in THIS PR
(#6152) because _MAX_MSG_LIMIT is defined here. The frontend _MSG_LIMIT_MAX
mirror lives on #6154 (not master yet), so the assertion SKIPS when the JS
constant is absent and activates automatically once both branches land on master.
The guard: extract _MAX_MSG_LIMIT from api/routes.py and _MSG_LIMIT_MAX from
static/sessions.js via regex; assert equality when both present. If they drift,
load-older silently stalls at the wrong value (the exact regression #6154 fixed).
Retired by #6177 (metadata-exposure), which removes the mirror entirely.
Verified: on this branch the cross-check SKIPS (_MSG_LIMIT_MAX absent, as
expected — #6154 not landed) and the backend-existence test PASSES. Extraction
logic confirmed correct against simulated match (500==500 passes) and drift
(999!=500 fails) cases.
Model Used: builtin:zai-coding-plan/GLM-5.2 (ZCode agent).
* fix(session): prevent silent row-loss in msg_limit ceiling paging (gate follow-up)
Adversarial review of #6152/#6154 reproduced two silent row-loss regressions in
static/sessions.js; both fixed here, plus a stale source-string assertion update
and the CHANGELOG entry:
1. _loadOlderMessages: gate the suffix-continuity heuristic on !useBeforePaging so
a raw-row-heavy msg_before cursor page whose visible text repeats the current
tail can't be misclassified as the cumulative tail and wholesale-replace it
(previously dropped 470 of 940 rows). msg_before pages are always prepended.
2. loadSession same-session refresh: only apply the width-hint msg_limit when it
is <= _MSG_LIMIT_MAX; above the ceiling the backend would clamp and silently
shrink an already-loaded >500-row transcript to the last 500. Over-ceiling
reloads now use the bare full-transcript path (no msg_limit / no expand_renderable).
3. tests/test_webui_external_refresh_frontend.py: update the reloadLimitParam
source assertion to the boundedReloadLimit form.
Re-gate: Codex adversarial SAFE TO SHIP (940/940 rows retained on cursor paging,
1000/1000 on refresh, no seam duplication, small sessions still use the fast tail
window); targeted + sessions/pagination/regression suites green.

* test: fix two node-harness tests broken by the boundedReloadLimit change
- test_issue3162_ensure_messages_loaded: replace the brittle fixed 4500-char
window (which the boundedReloadLimit lines pushed the carry-forward past) with
robust brace-balance function-body extraction.
- test_cross_session_message_load_isolation: define _MSG_LIMIT_MAX=500 in the node
harness env; _ensureMessagesLoaded now references it, and an undefined value made
boundedReloadLimit=null -> the fetch URL dropped msg_limit/expand_renderable and
mismatched the ordered api() harness -> stall/timeout.
