Codex SILENT finding: the new 'if not target.exists(): return {}' guard ran
BEFORE the ambient-resolver short-circuit, so a matching ambient profile home
whose directory does not physically exist (fresh install / monkeypatched cfg)
returned {} instead of deferring to get_config() — breaking in-memory overrides
and changing the default-profile missing-home path. Move the guard below the
ambient short-circuit; add a regression test (matching-but-nonexistent ambient
home still defers to get_config()).
CI failed on shard 2 across ALL python versions (deterministic, not a flake):
test_list_profiles_prefers_matching_isolated_default_home did
mock.patch('hermes_cli.profiles.list_profiles', ...), whose string target forces
a REAL import of hermes_cli — not installed on the WebUI CI path (bundled agent
absent) -> ModuleNotFoundError. Passed locally only because hermes_cli is
importable here. Per the never-import-agent/hermes_cli-in-a-WebUI-test rule:
inject a stub hermes_cli + hermes_cli.profiles into sys.modules so
list_profiles_api()'s internal
resolves to the stub at the WebUI boundary. Verified: all 24 tests pass with
hermes_cli import BLOCKED (CI simulation).
The reload-based state-dir tests (importlib.reload(api.config) with mutated env)
leaked recomputed STATE_DIR/SESSION_DIR globals + stale references into later
tests in the full sequential run -> 17 spurious failures in cancel/stream/
health/state-isolation suites (all green in isolation). Restoring env + reloading
couldn't fully undo it (fixture/monkeypatch teardown ordering + other modules
holding by-value STATE_DIR refs). Rewrite the 3 tests to import api.config in a
fresh SUBPROCESS under the target env and read STATE_DIR from stdout — truly
isolated, can't pollute the test process. Same assertions (HERMES_HOME-derived
default, unset->platform default w/ cross-check, STATE_DIR override precedence).
Opus flagged a real upgrade gap on the #4449 state-dir contract folded into
#4454: a deployment that relocated HERMES_HOME to a non-default base WITHOUT
setting HERMES_WEBUI_STATE_DIR sees WebUI state move to $HERMES_HOME/webui on
upgrade (empty app at the new address). Add (1) README note documenting the
move + how to keep the old location, and (2) two backward-compat regression
tests pinning the invariants: HERMES_HOME-unset stays at the platform default
(normal installs don't relocate), and HERMES_WEBUI_STATE_DIR takes precedence.
The /api/profiles handler re-imported _is_isolated_profile_mode locally inside
handle_get, which made the name function-local for the ENTIRE handle_get scope
-> the earlier use at the /api/projects branch (routes.py:8000) hit
UnboundLocalError (F823), failing 6 test shards + lint. It's already a
module-level re-export (routes.py:429), so the local re-import is redundant;
removing it lets every in-function use resolve to the module global. Also drop
an unused 'from pathlib import Path' in the new #4449 state-dir test.

Codex SHIP-WITH-FIXES: non-done terminal paths (apperror/cancel/stream-error
finalize) didn't clear _STREAM_WAS_HIDDEN, so a stale wasHidden=true could be
inherited by a later same-sid reconnect -> spurious notification. Make each
entry stream-owned ({streamId, wasHidden}) so a stale entry from a prior stream
is never trusted (reconnect keeps state only when streamId matches; done reads
via the owned entry), and add _clearStreamHidden(activeSid, streamId) on the
apperror/cancel/finalize-fallback terminal paths (belt-and-suspenders).
A background tab's SSE is throttled by Chromium, so the stream 'done' event
arrives late (after the user returns, document.hidden=false) and the
response-complete notification was suppressed by the live visibility check.
Track per-stream whether the tab was hidden at ANY point during the stream
(_STREAM_WAS_HIDDEN, set at attach, OR'd by one idempotent visibilitychange
listener, read+cleared at done) and pass forceHidden accordingly.
sendBrowserNotification bypasses ONLY the live visibility gate on forceHidden,
still honoring the user's notifications-enabled setting — so a watched stream
stays silent (matches Slack/Discord/Gmail/Claude) but a backgrounded one
notifies. Correct fix for the #4416 root cause; supersedes #4421's always-fire
approach (which would also fire when the tab was never hidden).

Gate-found (Opus SHIP-WITH-FIXES; Codex SAFE — split resolved by reading the
contract: no dropped-turn, but a real transient start-race flicker). #4424
removed the _sendInProgress guards entirely; that re-opened the #2689 start-race
SYMPTOM for the one session mid-send (a /api/sessions poll landing during the
/api/chat/start round-trip would blank the just-sent bubble + queue a spurious
force-reload). Re-add the guard SCOPED to sid===_sendInProgressSid only, in both
_reconcileActiveSessionIdleStateFromList and _purgeStaleInflightEntries — a
long-hung session has _sendInProgress===false so it still gets unstuck (#4354),
only the in-flight start window is protected. Also fixes Opus's test-masking
finding: test_inflight_send_start_race now strips JS comments before asserting +
requires a real , so a comment can't green-light the #2689 guard, and
adds coverage for the reconcile path.

for health/background-wakeup/agent-cache consumers. Add a 'not in STREAMS'

The pre-session toolset comment pushed the #2518 provenance comment past the
test_issue2518 4000-char window assertion. Trim the comment to one line and
widen the test window to 5000 (the fallback block it actually guards is well
within range; newSession() has legitimately grown).
Gate-found: staged _pendingSessionToolsets could leak into a later New Chat
started from an existing session (newSession forwarded it whenever it was an
array; loadSession never cleared it). Gate the forward on !S.session and clear
the staged value when a real session loads. +2 regression tests.

Codex gate caught that the new load_pool() path runs under the process-default

Without it a multi-profile client sees+seeds the default profile's pool

Codex CORE findings on the fingerprint: (1) default busy timeout could stall
/api/sessions ~10s on a locked state.db; (2) COUNT(*) forced a full messages
table SCAN (~16-22ms/refresh on 200k rows). Fix: open file:...?mode=ro with
timeout=0.05 + PRAGMA busy_timeout=50 (returns fast, falls back to stat stamp on
lock), and use index-only MAX(rowid) per table (no COUNT, no scan). Verified:
EXPLAIN shows SEARCH not SCAN, 0.36ms on 200k msgs, 0.16ms while EXCLUSIVE-locked.
Fingerprint shape is now (sessions_max_rowid, messages_max_rowid); regression
tests updated.
Codex root-cause consult confirmed: the CLI-session cache (_CLI_SESSIONS_CACHE,
5s TTL) and session-list cache were keyed on (st_mtime_ns, st_size) of state.db
+ WAL sidecars. Under WAL-mode writes those stamps collide (same mtime-ns bucket
+ WAL frame size after checkpoint), serving a stale cache -> freshly-committed
gateway/CLI session intermittently absent from /api/sessions (the recurring
test_gateway_sync flake AND a real up-to-5s sidebar delay for gateway writes).
PRAGMA data_version is NOT usable here (fresh per-request connection always
reports its own initial value, never advances — verified). Fix = a cheap
content fingerprint (COUNT/MAX(rowid) over sessions+messages) read on a fresh
connection, which DOES advance on every commit and is immune to mtime
granularity. Wired into _sqlite_file_stat_cache_key (models) + the routes-layer
source stamp. + 3 regression tests + corrected the earlier false root-cause
comments.
Codex completeness finding: show_previous_messaging_sessions is a third
visibility setting in the /api/sessions cache key (bypasses messaging dedupe)
with the same stale-cache bug. Added it to the invalidation tuple.
ROOT FIX (product bug): POST /api/settings never invalidated the session-list
cache, so toggling show_cli_sessions/show_cron_sessions could serve a stale
sidebar for up to the cache TTL when the settings-file mtime stamp collided with
a cached entry. The handler now clears the cache directly on those toggles. This
is also the root cause of the recurring test_gateway_sync CI flake (session
absent from /api/sessions right after the visibility toggle).
DEFENSE-IN-DEPTH: cleanup_test_sessions fixture now resets show_cli_sessions to
default BEFORE each test too, not only in teardown.
FLAKE FIX (test infra): bump 31 node-subprocess correctness-harness timeouts from
10s -> 30s across 23 test files. Node spawn + V8 warmup under parallel CI shard
load can exceed 10s, causing TimeoutExpired flakes (e.g. test_1325 on #4445).
Only real node subprocess.run() sites changed — mock signatures, HTTP urlopen,
and deliberate timeout-behavior tests (test_api_timeout, timeout=0/1/2) untouched.
Display-only sidebar fix (does not mutate archived state; rows reappear with
show-archived). Chosen as the interim #4293 fix since the backend-cascade
alternative #4423 was bounced for a fork-archival mutation bug.

Codex re-gate found two issues in the uncapped-read fix: (1) open_anchored_fd
opens blocking O_RDONLY, which HANGS on a workspace FIFO/special file swapped in
at a regular-file path; (2) the non-regular fstat branch returned without
closing the fd (leak). Fix: lstat the symlink-resolved target BEFORE any open to
skip non-regular leaves (no blocking open on a FIFO), and close the fd on the
non-regular fstat branch. Adds a threaded FIFO-no-hang regression test.
Codex regression gate found that routing workspace reads through
read_file_content() introduced a 400KB MAX_FILE_BYTES cap not present on master
(Path.read_text), so a large but legitimate workspace file raised ValueError ->
caught -> None -> the rollback diff falsely reported it as DELETED. Replace with
an uncapped anchored O_NOFOLLOW read (safe_resolve_ws + open_anchored_fd +
S_ISREG fstat check) that keeps the symlink-escape protection but has no size
cap. Adds a >400KB regression test (RED on the capped path, GREEN with the fix).

Codex regression gate found that _session_model_identity_matches normalized
only the @provider:model form, not provider/model (slash). A session stored as
'deepseek/deepseek-v4-1m' resolving to bare 'deepseek-v4-1m' was treated as a
model change -> the 256k fallback bypassed the accept-guard and clobbered the
persisted 1M window (the same #4248 bug on slash-qualified IDs). Mirror the
slash-aware split already used by _model_matches_configured_default. Adds a
route-level regression + unit test for the slash shape.

A user prompt that exists only in Hermes state.db (no sidecar copy) and falls
chronologically BEFORE a newer sidecar message tail was being appended after the
tail (or skipped) by merge_session_messages_append_only — losing or mis-ordering
it on load. The merge now inserts such a state.db user message at its correct
chronological position via _insert_state_message_chronologically, with a
role-aware tie-break for equal timestamps. Append-only invariant + dedup
(seen_content_keys) preserved.
Deterministic-ordering guard (maintainer add, addresses Codex review): on an
equal-timestamp collision the insert no longer lands at a slot whose left
neighbour shares the message's role — it advances past the same-role
equal-timestamp run, so an already-answered earlier turn can't be re-ordered
into user,user,assistant. (The agent core merges adjacent users before send, so
this was benign in practice, but the guard keeps the merged transcript correctly
ordered regardless.) +1 same-second multi-turn regression test, toothless-checked.

Multi-container Docker deploys died at startup with 'could not create
hermes_agent.egg-info: Permission denied'. docker_init.bash stages the :ro
hermes-agent-src into /tmp/hermes-agent-build to avoid EROFS, but rsync -a/cp -a
preserve mode bits — a source mounted 555 left the staged copy 555, so
setuptools couldn't write egg-info next to the package. chmod -R u+w the staged
tree after the copy (error_exit on failure) so the build dir is genuinely

Follow-up to #4385/#4388: that fix stopped stale cron sidecars from being
treated as CLI rows, but get_cli_sessions() still re-projected the same cron
run from Hermes state.db with a hardcoded archived: false after all_sessions()
omitted the hidden sidecar — so an archived run reappeared on refresh.
- New _state_projection_sidecar_metadata(sid) helper returns UI-owned title +
archived flag from the WebUI sidecar (load_metadata_only), degrading
gracefully to {title:None, archived:False} on any miss.
- Both state.db-projection paths (standard CLI + cron fallback) now use it and
carry the archived flag onto the projected row (was hardcoded False), so an
archived cron/tool/API run stays hidden regardless of which path surfaces it.
Title-preference behavior (#1486 rename persistence) is preserved.

- Hamburger button: 32x32 -> 44x44 tap target (iOS HIG minimum), SVG icon
20 -> 24px. flex-shrink:0 preserved; spacer keeps the title centered.
- Edge-swipe-to-open-sidebar: edge zone 28 -> 80px, trigger 72 -> 64px, max
vertical 48 -> 56px; removes the _isPwaStandalone() gate in
_onPwaSidebarSwipeStart so the gesture works in a normal mobile browser, not
only the installed PWA. Still _isDesktopWidth()-blocked, touch/pen-only,
interactive-target-excluded, and requires horizontal intent (dx>=64 &&
dx>|dy|*1.5), so scroll/tap won't trigger it.
Known tradeoff (Nathan-approved ship-as-is): in mobile BROWSER the 80px left
edge zone overlaps iOS Safari's back-swipe; degrades gracefully (PWA, the
primary mobile target, has no back gesture).
Verified live at 390x844: hamburger renders 44x44 + tap opens sidebar; a
left-edge swipe opens the sidebar in a non-PWA context. 66 existing mobile/
swipe/titlebar tests pass.

Paused/disabled cron jobs are partitioned out of the active list into a
collapsible 'Paused (N)' <details> section so they don't drown the active
jobs. _cronList stays the single source of truth — only the render is split,
so openCronDetail / _cronNewJobIds / detail-refresh are untouched. Reuses the
already-translated cron_status_paused label (zero new i18n keys). Collapsed
state persisted in localStorage.
Maintainer polish on absorb: wrapped both localStorage read/write in try/catch
(repo convention — a storage throw in private mode must not dump the cron
sidebar into the error banner) + added the CHANGELOG entry.

The A3 flake (test_sessions_response_backfills_imported_messaging_source_metadata
failing with StopIteration on a sharded CI run while passing in isolation +
sequentially) had two compounding causes, both fixed:
1. ROOT CAUSE — show_cli_sessions setting leak across shard-ordered tests.
33 gateway_sync tests flip show_cli_sessions=True but only ~30 reset it,
and cleanup_test_sessions didn't reset it. Under pytest-shard ordering a
test could run with the setting in an unexpected state, so its session was
occasionally absent from /api/sessions. cleanup_test_sessions now resets
show_cli_sessions to its default (off) after every test, the same way it
already resets last_workspace.
2. SYMPTOM — bare next(generator) with no default raised an opaque
StopIteration (read as a mystery flake) instead of a diagnosable failure
when the session was absent. The 5 bare next() call sites over /api/sessions
results now use next(..., None) + an explicit assertion naming the missing
session, so any future isolation regression fails clearly instead of
masquerading as a flake.
No production code change; tests + fixture only.
Two coherent fixes for the #4346 transcript-virtualization scroll-jump
cluster, shipped together (contributor-approved) because both touch
static/ui.js + the same virtualization test file and interact (the
cache-reset path uses the per-role default from #4367). Both only run when
the default-OFF experimental "Virtualize long transcripts" setting is on.
#4367 — per-role virtual scroll height estimates:
Replaces the flat 140px unmeasured-row estimate with per-role fallbacks
(user 120 / assistant 160 / tool_call 400 / default 140) via
_messageVirtualDefaultHeightForRole + _messageVirtualRoleForEntry, so
tool-call rows (which measure 500-2000px) aren't under-counted before
measurement. Additive + backward-compat (opts.roleForIdx optional → flat
default when absent). The two sibling offset calculators route through the
per-role defaults too.
#4368 — anchor-based scroll compensation during measurement:
Adds _compensateScrollForMeasurementDelta (capture anchor + scrollTop →
render → re-pin scrollTop by the anchor row's measured delta; null/missing/
<2px guards; programmatic-scroll flag managed) wrapping
renderMessages({preserveScroll:true}) in _scheduleMessageVirtualizedRender,
plus a 150ms scroll-active guard deferring measurement refresh while the user
scrolls, and session-switch cleanup of the three scroll-settle globals.
Maintainer note: combining the two required the test harness for
test_clear_height_cache_resets_scroll_settle_globals (#4368) to also eval
_messageVirtualDefaultHeightForRole + define MESSAGE_VIRTUAL_DEFAULT_ROW_HEIGHTS
(#4367), since the combined _clearMessageVirtualHeightCache resets the estimate
via the per-role helper. Both PRs' test sets retained.

A stale sidecar with is_cli_session=true could make an archived
cron/tool/API session resurface in the Sessions tab on refresh. The
session loader now treats explicit cron/tool/api source metadata as
non-CLI even when the sidecar claims is_cli_session, and preserves cron
identity when the archive/materialization fallback creates a session.

Adds WebUI controls to manage the messaging gateway lifecycle without a
terminal. _handle_gateway_lifecycle routes start/stop/restart to the
existing platform-aware `hermes gateway {action}` CLI via a list-argv
subprocess (no shell), scoped to the active profile, with bounded
timeout/error handling and a status-card refresh. Auth + CSRF gated;
profile name charset-validated; stdout/stderr never leaked to the client.
Maintainer hardening (warm-up SHOULD-FIX): added _GATEWAY_ACTION_LOCK, a
server-side single-flight guard. The client disables its button in-flight,
but a scripted authed client could otherwise fire overlapping
start/stop/restart calls and spawn concurrent gateway subprocesses. A
non-blocking acquire now returns 409 on contention (mirrors the self-update
_apply_lock pattern), released in finally. Added a regression test
(toothless-checked: without the lock the 2nd action spawns a subprocess +
returns 200).
Cross-platform: delegates to the mature hermes_cli gateway subcommand
(systemctl/launchctl), pathlib paths, PYTHONUTF8=1 + BROWSER=echo in env.

The inline PDF preview rendered only page 1, so multi-page documents
looked clipped. loadPdfInline now renders every page (capped at MAX_PAGES=20
for memory) sequentially into a scrollable .pdf-preview-body, shows the page
count in the header, and appends a "Showing the first N of M pages" notice
(pdf_truncated, 13 locales) when the PDF exceeds the cap.
Robustness: renderPage(i) attaches each canvas only AFTER its render
promise resolves, and a per-page failure is caught and skipped
(`.then(()=>renderPage(i+1)).catch(()=>renderPage(i+1))`) so one corrupt
page can't halt the preview or surface an unhandled rejection. XSS-safe
(esc(fname), t() with numeric args).
