Without this check, switching browser tabs while a stream is running
causes finalizeThinkingCard() to operate on the wrong session's
thinking card DOM — the card belongs to the stream that started it,
not the session currently displayed in the tab. The guard ensures
finalize only runs when the live assistant turn's session matches
the current session.

Follow-up to v0.50.249 / PR #1365 absorbing Opus SHOULD-FIX #2.
Originally reset out of #1365 because the reviewer flagged it as
out-of-scope; brought back per follow-up guidance that
correctness-improving changes should ship even when out of scope.
The clarify SSE health timer at static/messages.js:1715 was an
unconditional 60s force-reconnect, not the 'no event in 60s' detector
its comment claimed. Now actually a stale-detector that tracks
lastEventAt on initial+clarify event arrivals; only reconnects when
the gap exceeds 60s. Under healthy conditions the timer never fires.

Replaces the 1.5s HTTP polling loop for clarify with a Server-Sent Events endpoint at /api/clarify/stream that pushes clarify events to the browser instantly. Mirrors the approval SSE pattern from v0.50.248 (#1350) including all the correctness lessons:
- Atomic subscribe + initial snapshot under clarify._lock
- _clarify_sse_notify called inside _lock for ordering guarantees (no notify-out-of-order race)
- Notify passes head=q[0].data (head-fidelity, not the just-appended entry)
- resolve_clarify also calls notify after pop so trailing clarifies surface immediately (no stuck-clarify bug)
- Empty-state notify with None,0 after pop-empty so frontend hides the card
- 30s keepalive comments, _CLIENT_DISCONNECT_ERRORS handling
- Bounded queue (maxsize=16) with silent drop on full
- Frontend: EventSource with automatic 3s HTTP polling fallback on onerror

Adds a 'storage' event listener for the hermes-webui-session localStorage key. Idle tabs auto-load the new active session and re-render the sidebar; busy tabs show a toast and do not interrupt the active turn.

When a session's compression lineage spans multiple segments (linked via _lineage_root_id from api/agent_sessions.py), the sidebar previously rendered each segment as a separate top-level row. Adds _collapseSessionLineageForSidebar() that groups by lineage root and keeps only the most recently active tip per group, with a _lineage_collapsed_count marker for future UI affordances.

- api/streaming.py SSE payload now falls back to agent.model_metadata.get_model_context_length when compressor doesn't supply context_length (mirrors the session-save fallback shipped in v0.50.247).
- api/streaming.py also falls back to s.last_prompt_tokens to avoid using the cumulative input_tokens counter.
- static/ui.js tracks rawPct separately from pct and shows '(context exceeded)' tooltip when rawPct > 100 instead of misleading '100% used (0% left)'.
- static/messages.js clears 'Uploading...' composer status after upload completes.

Pre-release Opus review caught three correctness bugs in the original
PR #1350 SSE wiring beyond the snapshot/subscribe race:
A) **Notify-ordering race (MUST-FIX A):** _approval_sse_notify took _lock
only for the subscriber-list snapshot, then released it before
put_nowait. With two parallel submit_pending calls, T2's notify
could fire before T1's, leaving the UI showing pending_count=1 while
the server actually had 2 queued.
C) **Trailing approval lost (MUST-FIX C):** _handle_approval_respond
never called _approval_sse_notify after popping. With parallel
tool-call approvals (#527), a second approval queued behind the one
being responded to was invisible until the next event ever fired —
in practice, the agent thread parked on it would appear hung.
D) **Payload showed tail not head (MUST-FIX D):** payload built from
the just-appended entry instead of queue[0]. /api/approval/pending
returns the head; SSE returned the tail. Diverging contracts.
Fix:
- Split into _approval_sse_notify_locked (caller holds _lock, no
internal locking) and _approval_sse_notify (convenience wrapper).
- submit_pending: call _locked variant inside the queue-mutation lock,
passing queue_list[0] as head.
- _handle_approval_respond: call _locked variant inside the pop lock,
passing the new head (or None/0 if queue is empty).
- Restore fallback poll to 1500ms (was bumped to 3000ms; degraded-mode
parity with v0.50.247 is more important than save 1.5s of polling).
New regression tests in tests/test_pr1350_sse_notify_correctness.py:
- test_second_submit_pending_sends_head_not_tail (D)
- test_respond_to_first_pushes_second_as_new_head (C)
- test_respond_to_only_pending_pushes_empty_state (C edge)
- test_pending_count_is_monotonic_under_contention (A)
Updated test_approval_sse.py to pin the new contract:
- _approval_sse_notify_locked(session_key, head, total)
- 1500ms fallback interval
Total: 3411 tests passing.

Replaces the 1.5s HTTP polling loop with a Server-Sent Events endpoint
at /api/approval/stream that pushes approval events to the browser
instantly. The backend uses a thread-safe subscriber registry
(_approval_sse_subscribers) with bounded queues to prevent memory
leaks from slow clients. Frontend uses EventSource with automatic
fallback to 3s HTTP polling on SSE error.
- Backend: subscribe/unsubscribe/notify lifecycle in api/routes.py
- New route: GET /api/approval/stream?session_id=
- submit_pending() now calls _approval_sse_notify() after queue append
- Frontend: EventSource with onerror -> _startApprovalFallbackPoll()
- 30s keepalive comments, _CLIENT_DISCONNECT_ERRORS handling
- 42 new tests (static analysis + unit + concurrency)

Frontend companion to backend fix in v0.50.246 (#1341 + a5c10d5).
Default context window to 128K when usage.context_length is falsy.
Show '(est. 128K)' label when using the default.
Use input_tokens as fallback for last_prompt_tokens.

From PR #1338. Already independently APPROVED by nesquena before being absorbed into v0.50.246.
CHANGELOG entries from this PR were dropped during squash (the v0.50.245 section is already
shipped); they will be re-added under [v0.50.246] in the release commit.

release: v0.50.243
Batch release of 2 PRs.
- #1301 — fix: remove PRIMARY chip badge + add Claude Opus 4.7 label
Drops the chip-projected configured-model badge added in #1287 (chip
width 235px → 164px). Adds Claude Opus 4.7 label entries so the picker
no longer renders "Claude Opus 4 7" (missing dot).
Independently reviewed and approved by nesquena (commit c0bbd23).
- #1297 (@franksong2702) — fix: preserve cron output response snippets
Fixes#1295. /api/crons/output now preserves the ## Response section
when a large skill dump appears in the prompt section; falls back to
file tail when no marker exists.
Tests: 3254 passed, 2 skipped, 3 xpassed.
Independently reviewed and approved by nesquena (commit b262e4d).
Reverts the global assistant serif rule and removes the Calm theme that were shipped in v0.50.240 PR #1282. Pure deletion; 3252 tests passing. Override on independent review per Nathan.
The post-stream renderMd() in static/ui.js only handled #, ##, ### — lines starting with #### through ###### fell through and emitted as literal text after streaming finalized.
Extend the heading replacer chain to cover h4-h6, ordered longest-first, so ###### cannot be partially captured by the shorter ### rule. Add the matching .msg-body h4/h5/h6 CSS rules (and data-font-size variants) so the new tags inherit the same visual rhythm as h1-h3.
Adds 3 node-driven tests in test_renderer_js_behaviour.py pinning all six heading levels and the longest-first replacer order.
Closes#1258

B1: fix stored XSS in MCP delete button — replace inline onclick with
data-mcp-name attribute + event delegation (panels.js)
B2: fix zip/tar-slip via startswith prefix collision — use
is_relative_to(); track actual extracted bytes instead of trusting
member.file_size (upload.py)
B3: add NVIDIA NIM endpoint to _OPENAI_COMPAT_ENDPOINTS and
_SUPPORTED_PROVIDER_SETUPS so provider is reachable (routes.py,
onboarding.py)
H1: add terminalResizeHandle element to index.html and return it from
_terminalEls() so resize-by-drag works (index.html, terminal.js)
H2: fix dead get_terminal() branch — return None for dead terminals
instead of always returning term (terminal.py)
H3: replace os.environ.copy() with a safe allowlist in PTY shell env
so API keys are not exposed inside the terminal (terminal.py)
H5: make model dedup deterministic — sort groups by provider_id
alphabetically before first-occurrence assignment (config.py)
H7: add pid regex validation before OAuth probe; constrain key_source
to a closed set of safe values (providers.py)
M8: add double-run guard for cron run-now — reject if job is already
tracked as running (routes.py)
Addresses reviewer feedback on #524 — the compress affordance was only
reachable via hover (desktop). Mobile users can now tap the context ring
button to toggle the tooltip and access the compress button.
- CSS: add .ctx-tooltip-active class with opacity + pointer-events
- JS: tap-to-toggle handler on ctxIndicator with outside-click dismiss
- aria-hidden toggled correctly for accessibility
