Add readyState !== CLOSED (2) guards to all EventSource.close() calls across
messages.js, sessions.js, panels.js, and terminal.js. Chromium reports
net::ERR_ABORTED when close() is called on an already-closed EventSource,
polluting the console during normal lifecycle transitions (session switch,
panel close, stream teardown).
Key hotspots:
- closeLiveStream() double-close via onerror → _closeSource chain
- _closeSessionEventsSSE, _gatewaySSE.onerror missing try/catch
- _kanbanStopPolling, terminal close handlers
20 close() calls guarded across 4 files, no structural changes to stream
lifecycle.
"Reply with selection" no longer appends the selected text straight into
the composer. It now adds a named chip ("Context N") to a row above the
message box (composerSelectionChips). Chips can be renamed (double-click,
esc()-escaped) or removed (x); multiple stack. On send(),
_flushSelectionBlocksToComposer() materializes pending blocks into the
composer as **Name:** + markdown-quoted text, then the normal send path
runs unchanged on composer.value.
Regression-safety:
- _flushSelectionBlocksToComposer early-returns when no blocks are pending,
so send() is byte-identical for anyone who never uses the feature.
- loadSession() AND newSession() both clear pending blocks before replacing
S.session, so chips never leak across a sidebar switch OR a New Chat
(the New Chat clear + its regression test were added per Codex review).
- chip name/text rendered via esc(); XSS-safe.
Verified live (headless CDP drive): add/render/remove/rename, flush
produces correct markdown, empty-flush no-op, session-switch clears,
injected <img onerror=...> chip-name escaped (not executed).

Ships @dso2ng's fix: /api/session now reconciles stale CLI source flags
against the state.db WebUI-origin row, and _isExternalSession() refuses to
classify an explicit WebUI-source session as external — so a WebUI-native
transcript with a stale sidecar isn't force-reloaded like an imported one.
Rebased onto master (contributor's net code-diff applied; byte-identical to
PR head). CHANGELOG stamped v0.51.474.

Sidebar vanished during resilient/slow session loads. Preserve sidebar
fields on resilient loads + add an opt-in api() retry so a slow /api/sessions
shows a retryable error state instead of an empty sidebar.
Maintainer fixes for the 3 review-blocking SILENT regressions:
- Restore read_only / is_read_only / gateway_routing to the sidebar response
allowlist, so read-only (imported CLI + Claude Code) sessions keep their
rename/action-menu/swipe suppression and the gateway model label renders.
(gateway_routing_history intentionally NOT sent — the label reader prefers
the latest gateway_routing, and the full history would bloat each row.)
- Scope-tag the session cache (active profile + all-profiles flag). When a
/api/sessions refresh fails right after a profile switch, the catch path now
clears the stale rows and shows the error state instead of re-rendering the
PRIOR profile's sessions.

* Release PL (v0.51.451): show named-profile external sessions in the all-profiles list (#4067, #4065)
All-profiles session enumeration now scans across profiles only when the
request explicitly asks (all-profiles view); cross-profile import resolves
to the active profile's state.db for unqualified requests (foreign id -> 404),
mirroring the #3982/#3991 detail/export profile-scoping gate.
Co-authored-by: rodboev
* gate fix (Codex CORE + Opus): close cross-profile leak on the import_cli refresh/existing-session branch
The already-imported branch of _handle_session_import_cli forced allow_all_profiles=True
whenever the globally-stored session carried a profile, with no active-profile visibility
gate — so an unqualified request from profile A could read/refresh a session imported under
profile B's live state.db (both advisors reproduced the foreign-transcript leak). Now gated
exactly like the /api/session detail + export endpoints: unqualified requests require
_session_visible_to_active_profile; explicit all_profiles requires a matching profile.
+ 3 regression tests.
* gate fix (Codex SILENT, re-gate): thread source_filter into the all-profiles CLI scan (models.py:4113)
The all-profiles branch keys its cache on source_filter but called
_load_cli_sessions_uncached without it, so /api/sessions?all_profiles=1 with a
source filter returned every-source sessions under a filtered key. + regression test.

* stage-3629: scope gateway watcher to active profile (profile-keyed registry), rebased onto master
* stage-3629: + stop-race-safe subscribe() (Codex CORE) + regression test
Codex caught a TOCTOU between get_watcher() and subscribe(): a watcher reaped as
subscriber-free during a concurrent profile switch left a late subscriber's queue
without the None sentinel -> SSE loop hangs open (keepalives, no events). Opus
independently found the same race (rated follow-up). subscribe() now checks
_stop_event under _sub_lock after appending and self-enqueues the sentinel.
test_subscribe_after_stop_gets_sentinel_immediately pins it.
* stage-3629: + reconnect gateway SSE to new profile on switch (Codex CORE #2)
Second Codex finding: after a profile switch this tab's _gatewaySSE stayed
subscribed to the PREVIOUS profile's watcher (switchToProfile never restarted it;
the probe reattach is gated on !_gatewaySSE which is false while the old ES is
open). switchToProfile() now calls startGatewaySSE() after S.activeProfile is set
— it closes the old ES + reconnects with the new profile cookie, self-gating on
_showCliSessions.
* Release PF: scope gateway watcher to active profile (#2848)
rodboev's #3629, re-pushed to fix both bounce findings (client SSE reconnect +
singleton→profile-keyed registry). Two Codex CORE races caught + fixed inline:
(1) stop/subscribe sentinel race, (2) tab's own SSE staying on the old profile
after switch. Codex SAFE + Opus SHIP (architecture) + gateway-watcher tests green.

* fix: bound paginated session tails by visible messages
* fix(#4070): always merge state.db tail rows (drop the stale-tail timestamp shortcut)
Deep-review finding: the sidecar-only timestamp shortcut returned the sidecar
verbatim whenever state.db had no strictly-newer rows, but a state.db row
at-or-before the sidecar's newest timestamp (recovery / edited-in-place /
missing-timestamp) is still absent from the sidecar -> the paginated tail
diverged from the full merge path (empirically 3/6 adversarial cases). Always
run the cheap in-memory append-only merge; the real latency win (skipping the
lineage-parent DISK load) is preserved.

* fix(#4070): keep matching trailing tool-result row in paginated window
Codex ship-gate finding: _message_window_for_display pulled end_idx back to the
last renderable (user/assistant) row, dropping a trailing role:tool result row
even when it's the result of the newest assistant tool-call. The renderer
rebuilds tool cards from these rows (CLI-origin / empty S.toolCalls path,
static/ui.js resultsByTid), so the card lost its result snippet. Now extend
end_idx forward through trailing tool rows whose tool_call_id matches a tool-call
present in the window; orphan trailing tool rows (no match) are still skipped to
preserve the visible-row budget. +2 regression tests.

Opus gate nit: _max_message_timestamp was only called by the removed

api/models.py for its real callers.

* fix(#3714): preserve live turn on scroll-rebuild even with zero streamed text
Opus ship-review residual (now fixed, not deferred): the live-turn re-attach

turn showing only Activity/tool/worklog blocks with no streamed text yet (mid
tool-call) would not be preserved — scrolling up into history on a >80-row
transcript mid-stream could blink those live-only blocks for a frame. Broaden
the gate to also restore when the preserved turn has MORE structural blocks than
the rebuilt (lagging-S.messages) turn. Hoisted the _structuralCount helper above
the gate; whole-turn-vs-segment restore logic unchanged.

The #4151 focus hook reopened both global sidebar streams on `focus` with a
bare `startGatewaySSE()`. But `startGatewaySSE()` is NOT idempotent — it begins
with an unconditional `stopGatewaySSE()` (sessions.js:3778), which closes the
live gateway EventSource, cancels its poll fallback (`stopGatewayPollFallback`),
and resets `_gatewayProbeInFlight` / `_gatewaySSEWarningShown`.
So on a transient blur shorter than the 1s debounce — where the blur-close
timer is cleared on the following focus and the stream was never torn down —
the focus handler still dropped and reconnected the gateway on every
window-switch, cancelling its fallback and resetting probe/warning state. That
is the exact thrash the debounce exists to prevent, in the multi-window PWA
scenario this PR targets. (`ensureSessionEventsSSE()` is already idempotent via
`if(_sessionEventsSSE) return`, so the session-events stream was unaffected;
only the gateway churned. greptile P1.)
Guard the reopen on the gateway actually being closed: `if(!_gatewaySSE)
startGatewaySSE()`, mirroring the session-events idempotency. A sustained blur
(timer fires → both streams closed) still reopens the gateway on focus; a
transient blur leaves the still-open gateway untouched. Verified with a
blur/focus/timer harness (transient → no teardown/reconnect; sustained → close
then reopen; CLI-disabled → stays closed) and a new regression guard
`test_focus_reopen_does_not_thrash_the_gateway_stream`.

Two side-by-side PWA standalone windows saturate the browser's per-origin
HTTP/1.1 connection limit, causing 'Request timed out' toasts to cycle every
~30s. The idle-SSE close added in #3992/#3996 keys off the Page Visibility API
(visibilitychange / document.hidden), but a PWA standalone window does not
reliably fire visibilitychange when it loses focus to another window of the
same app -- document.hidden only flips on minimize. So both windows stay
'visible', each holds its two global sidebar SSE streams (session-events +
gateway) open, 2x3 = 6 hits the connection cap, and subsequent fetch() calls
(the 30s background polls) queue behind the saturated pool and time out.
The two global sidebar streams now also close on a sustained window blur (gated
on document.hasFocus(), the signal visibilitychange misses) and reopen --
catching up the session list -- on focus, via a shared _sidebarSseBackgrounded()
predicate and a debounced _installSidebarSseFocusHook().
The per-session live stream (messages.js startSessionStream) is intentionally
left visibility-only: it carries live bg_task_complete toasts and
server_turn_started live-view that an unfocused-but-visible window must still
receive (the OS-notification path is gated on document.hidden, so the in-app
toast is the only completion signal a visible-unfocused window gets). Closing
it on blur would regress the multi-window live-view UX.

Production fixes (Tamaz-sujashvili, reviewed sound by maintainer):
- loadSession clears S.busy/S.activeStreamId as soon as metadata confirms no active_stream_id, before the async message-load gap (idle session no longer shows streaming chrome).
- Snapshots the live turn before wiping msgInner + seeds INFLIGHT, restores on the active-stream return path (timer/trace survive switch-back).
Re-anchored the 2 brittle regression tests per maintainer review: test_..snapshots.. now anchors on the unique 'Loading conversation...' marker (was matching the no-space 'Session not available' error path); test_..restores.. now asserts the LIVE Phase 2a restore (after loadInflightState) instead of the unreachable Phase-2b/1184 branch. CHANGELOG stamped v0.51.384 (MW).
Opus advisor found a key-space asymmetry: _pruneLineageReportCacheToVisibleSessions
built visibleKeys from RAW rows via _sidebarLineageKeyForRow, but the render loop
keys the lineage-report cache by _sidebarLineageKeyForRow on the COLLAPSED row,
which can differ when collapse merges segments. On a malformed/edge chain the
expanded row's cache could be evicted every payload and re-fetched ~every 5s
(partial regression of the bug #4020 fixes). Fold the collapsed rows' cache keys
into the visible set too, mirroring the _resolveSessionIdFromSidebarLineage
precedent, behind a defensive try/catch.
docs(changelog): stamp #4020+#4055 as v0.51.373 (Release ML)
currentSid is snapshotted before the awaited /api/session fetch; if the user
clicks a healthy session while a boot-time restore is in flight and that boot
load then fails non-404, _clearStuckSessionOnBoot(sid, null) would wipe the
healthy session's localStorage/URL. Guard the catch block on
_loadingSessionId !== sid (a newer load superseded this one) — re-arm the active
stream and bail before any self-heal/DOM mutation. Protects both the non-404 and
404 inline self-heal paths. + regression test.
On 401, api() redirects to /login and returns undefined. The browser
navigates away immediately, so this code rarely runs. But even if it
did, clearing localStorage on transient auth expiry is wrong — it wipes
the saved session id and sends users to empty state after re-login.
Keep the self-heal in the catch-block else branch for non-401, non-404
errors (400/403/500/network) which genuinely trap the user on recurring
boot failures. 401 has no such property because the redirect already
breaks the retry loop.
Greptile: 'Keep the if (!data) early-return clearing-free (its old
behavior), and only call _clearStuckSessionOnBoot() from the else
branch of the catch.'
(#4028 follow-up)
The api() function returns undefined on 401 (redirects to login) rather
than throwing. So the 401 path exits via the if(!data) guard at line ~988,
not through the catch block — the e.status===401 branch inside the catch
is dead code (#4028 follow-up).
Greptile flagged that currentSid===sid also fires on same-session
force-reloads (e.g. background poll). If the server returns a transient
500 or network error, currentSid===sid is true — the helper wipes
hermes-webui-session from localStorage and resets the URL, even though
the session still exists on the server.
Limit the self-heal to boot-time failures only (!currentSid), where the
stored session ID is definitely stale. When currentSid is set (already
viewing a session), a non-404 failure could be transient and wiping
localStorage is unnecessarily destructive.
The 404 inline self-heal (line 932) already uses this tighter guard,
so this brings the non-404 path into alignment.
When loadSession() fails during boot with a non-404 error (401, 400,
500, network), the session ID stays stuck in localStorage and the URL,
causing repeated failures on every page refresh.
The 404 path already had inline self-heal (clears localStorage + URL).
This extends it to all error cases:
- Added _clearStuckSessionOnBoot() helper to consolidate the self-heal
logic for non-404 errors.
- On 401 redirect (api() returns undefined): clears the stuck session
ID and shows a more informative message.
- On other non-404 errors: clears the stuck session ID and shows a
better error message distinguishing auth failures from other errors.
Preserves the guard that prevents clearing localStorage when clicking
into a *different* dead session while already viewing a healthy one.
Adds a server-side run-journal live snapshot (_run_journal_live_snapshot) returned
in GET /api/session as runtime_journal_snapshot, so a FRESH client (another device,
or a tab with no in-memory snapshot) opening an in-progress session immediately sees
the already-streamed assistant text + tool cards rebuilt from the server. Composes
with the existing _replay_run_journal cursor path (seeds lastRunJournalSeq so replay
resumes from the snapshot cutoff, not duplicating it) and keys tool cards by the same
5 id aliases (tid/id/tool_call_id/tool_use_id/call_id) as #3763 so SSE replay replaces
rather than duplicates snapshot cards. Payload values truncated; redaction test added.

Two distinct timeout causes, both surfacing as the client's 30s 'Request timed
out' toast with no server-side signal:
A) /api/session/move acquired the per-session agent lock with a bare unbounded
'with _get_session_agent_lock(sid):'. The streaming thread holds that same
lock during checkpoint saves; on slow file I/O (WSL/DrvFs) the move could
block past the client abort. Now acquires with timeout=5 and returns HTTP 503
on contention (lock kept, not dropped, since s.save() still races the writer).
B) /api/projects/delete unlinked every assigned session via get_session()+save()
— O(N) full-messages reserialize. For an actively-streaming session we now
clear project_id on the LIVE CACHED Session object under LOCK (the streaming
thread persists it on its next save — the worker always does a final save at
turn completion) instead of issuing a competing s.save(); falls back to a
direct save when not cached. Non-streaming sessions unchanged.
Also guards the '+ New project and move' shortcut (sessions.js) against the new
503 so it shows a toast instead of an unhandled rejection, keeping the #2551
authoritative refetch in both the success and catch paths.
Adds tests/test_issue3746_session_move_delete_timeout.py (behavioral lock-timeout
test + structural guards for both handlers + the frontend 503 guard). Widened the
#2551 new-project-refetch test's fixed byte-window to a block-scoped search so the
try/catch wrap (which preserves the refetch) doesn't trip a brittle offset assertion.

1. start_session_turn now threads the session PROFILE model defaults
