Two related 'jump back' classes where a reader who is following the live stream
gets stranded mid-transcript, both verified live (OLD stranded the viewport
470-580px from bottom; FIX lands at 1px).
1. Content-grew-beneath-a-pinned-viewport (static/ui.js scroll listener).
While streaming on a tall transcript (especially on mobile, where chunks land
fast), new content increases scrollHeight under a stationary viewport. The
reader never scrolled (top did not move up, _messageUserUnpinned is false), but
bottomDistance crosses the nearBottom threshold, so the code fell through to
_scrollPinned=false, killing auto-follow mid-stream. The follow writer and the
scroll listener then fought frame-by-frame; the viewport stalled while content
kept growing and was progressively stranded. Fix: in the !_messageUserUnpinned
branch, when the viewport did NOT move up and auto-follow is on, keep the pin
and re-snap to the true bottom via _setMessageScrollToBottom() instead of
unpinning. The genuine scroll-away fallthrough is unchanged.
2. SSE-recovery follow-restore (static/messages.js). _handleStreamError (SSE
drop), the Task-cancelled apply + fallback paths, and the reconnect-stream-dead
cleanup all push/replace S.messages then renderMessages({preserveScroll:true}).
preserveScroll's restore path keys on the pre-render snapshot's bottom-distance,
which during a live stream can read large (content grew under a followed
viewport), so it yanked a following reader up to a stale historical position on
a process restart / SSE drop / cancel. Fix: capture follow-intent
(_isMessagePaneNearBottom) BEFORE mutating S.messages, and after the recovery
render, scrollToBottom() if the reader was following — so they see the
interruption/cancellation notice in place. Readers who scrolled up to read
history are left where they were.
Structural source-lock tests in tests/test_sse_recovery_scroll_stranding.py;
behavioral A/B verified via Playwright on a local source build.
test_error_reconnect_path_can_restore_from_journal anchored on the exact string
setComposerStatus('Reconnecting — but the first status was changed to a template
literal `Reconnecting… (1/${_retryDelays.length})` for the staged-probe counter,
so that single-quoted anchor no longer exists (ValueError: substring not found in
CI shard 2). Re-anchor on the block's stable entry point _reconnectAttempted=true;
(unique in source) and widen the window to 1100 chars; the st.active /
st.replay_available / Restoring stream / _runJournalReplayParams() assertions are
unchanged.

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.

* fix(#3401): resolve 4 deep-review regressions (inline-think, reconnect-dup, neon skin, busy-gate worklog)
Deep review (Codex diff-vs-master + live-browser drive) of the live-to-final refactor
surfaced 4 regressions vs master that the rewritten suite no longer guarded:
1. Inline <think>…</think>answer reasoning vanished — _assistantReasoningPayloadText
used $-anchored regexes so a leading think block + visible answer extracted nothing
and the Thinking card never rendered. Removed the 3 $ anchors to match the
(non-anchored) display stripper. Live: inline-think thinking-only turn now renders.
2. (CORE) reconnect/reload duplicated the live reply — _rememberRunJournalCursor advanced
a closure-local seq but never wrote INFLIGHT[activeSid].lastRunJournalSeq, so a reload
replayed the journal from after_seq=0 over restored lastAssistantText. Now mirrors the
cursor onto INFLIGHT + schedules a throttled persist.
3. Neon skin silently broke — PR deleted the :root[data-skin="neon"] CSS but left Neon in
the picker. Restored the neon CSS block from master.
4. Settled tool-worklog rebuild gated purely on !S.busy — dropped every prior settled
turn's worklog when renderMessages re-ran during an active stream (switch-back to an
in-progress session). Restored master's !S.busy || (S.toolCalls && S.toolCalls.length).
Live: busy re-render now preserves tool cards (4→4, was 4→0).
Live-verified all 4 + confirmed #3709/#3592 invariants still hold (1 thinking card, none
below footer; distinct siblings preserved). + tests/test_issue3401_deep_review_fixes.py (7).
* test(#3401): realign 3 stale source-shape assertions to the deep-review fixes
Fix commit changed two source literals that existing stage tests scanned for:
- test_live_activity_timeline.py (x2): split anchor 'if(!S.busy){' → the restored
'if(!S.busy || (S.toolCalls&&S.toolCalls.length)){' guard (fix 4).
- test_run_journal_frontend_static.py: 'after_seq=0' not in source — fix 2's comment
contained that literal; rephrased the comment to 'the zero floor (after_seq of 0)'.
Intent of all three assertions unchanged; only the matched string updated. No code
behavior change.
* docs(changelog): v0.51.294 — Release JJ (stage-3401, #3401 live-to-final redesign)

PR #2347 hoisted the inline state object to a `state` variable so the
auto-compression handler could share it with appendLiveCompressionCard.
Behavior is identical — same setCompressionUi() dispatch, same calm
compression-card path — but tests/test_run_journal_frontend_static.py
pinned the literal substring `setCompressionUi({` to verify the call
site. Relax the assertion to accept either inline (`{...}`) or hoisted
(`state`) argument form. Both forms route through the same compression
card path; the over-specific substring was the bug.
