rfind for the Phase-2 INFLIGHT branch (idle-reset added an earlier if(INFLIGHT[sid]){);
and test_load_session_attaches_sse_before_auxiliary_work now asserts each auxiliary call
individually (the old contiguous syncTopbar();renderMessages();appendThinking();loadDir
literal was legitimately broken up by the new restoreLiveTurnHtmlForSession insertion +
renderMessages(preserveScroll) arg — all calls still run after attachLiveStream). Behavior unchanged.
test_issue3306 _load_session_clear_block (4000->6500) + test_issue_new_chat_draft_restore
body window (4000->6500): #3899's idle-reset + live-turn-snapshot blocks pushed the
carry-forward snapshot + destructive S.messages clear past the old fixed windows. Behavior
+ ordering unchanged; windows widened to contain them.
#3899's new idle-reset added an EARLIER if(INFLIGHT[sid]){ block in loadSession, so
4 test_regressions tests' src.find('if(INFLIGHT[sid]){') grabbed the wrong (idle-cleanup)
occurrence instead of the Phase-2 restore branch → switched to rfind (the substantive
branch). And the idle-cleanup comment changed from 'discard any browser-side inflight'
to 'reset browser-side streaming flags' → re-anchored test_frontend_drops_inflight_cache
on the new comment + nested if(!activeStreamId){...if(INFLIGHT[sid]){ form (behavior
preserved + enhanced). No production code changed.
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).
_captureWorklogDetailDisclosureState stamps state._sid; _restoreWorklogDetailDisclosureState
skips restore on sid mismatch. Cross-session isolation no longer depends solely on the
sessions.js #msgInner wipe invariant — a future change to that loading-placeholder
behavior can't silently replay one session's collapse state onto another.
panels.js _autosaveAppearanceSettings (6309) + _applySavedSettingsUi (7837) read
auto_scroll_follow from a settings/body object — use !==false (default True) for
consistency with boot.js + the checkbox render, so a future partial-body refactor
can't silently default the True setting OFF. The .checked reads (6223/8170) keep !!
(a real bool).
scrollToBottom now calls _settleMessageScrollToBottom(false, true); renderMessages
captures scrollSnapshot when (preserveScroll || (!_autoScrollFollow && _messageUserUnpinned)).
Updated the 4 change-detector assertions in test_tars_scroll_reset_regressions.py +
test_issue1690_scroll_completion.py to the new strings; behavioral intent unchanged.
1. _settleMessageScrollToBottom(force, explicit): when explicit (End-button /
scrollToBottom), late-layout settling runs even with Auto-follow OFF — the
setting only suppresses AUTOMATIC follow, not a deliberate jump. The RO + 2s
fallback guards now bail on (!_autoScrollFollow && !explicit). scrollToBottom()
passes explicit=true; the automatic scrollIfPinned() path stays guarded.
2. renderMessages now captures the pre-wipe scrollSnapshot when (Auto-follow off
&& user unpinned) too, so the non-preserve restore lands the reader where they
were instead of receiving a null snapshot (no-op).
The keys shipped only in en+zh; added it/ja/ru/es/de/zh-Hant/pt/ko/fr/tr/pl so the
Settings → Appearance auto-follow toggle isn't English-only outside those two.
Codex found that with Auto-follow OFF the #3920 ResizeObserver settle + 2s fallback
+ the non-preserve render path still force-scrolled to bottom (the setting was
incomplete vs the scroll machinery shipped in #3920). Fixes:
1. RO settle guard (ui.js:3153): bail when !_autoScrollFollow.
2. 2s static fallback guard (ui.js:3186): bail when !_autoScrollFollow.
3. non-preserve render fall-through (ui.js:8653): when Auto-follow off AND the user
has unpinned, restore the scroll snapshot instead of scrollToBottom() — also
closes the send() race (renderMessages runs before S.activeStreamId is set).
A fresh session load (not unpinned) still lands at the bottom. Explicit
user-initiated scrollToBottom() (End button) is untouched.
Per maintainer decision, auto_scroll_follow defaults TRUE (sticky-bottom: follow
new output while streaming, scroll-up unpins and is respected) — matching Codex
CLI / Claude Code. The PR shipped it default-False.
Default-mismatch bug fixed (would have shown the True default as OFF for existing
users with no saved value):
- boot.js settings path: !!s.auto_scroll_follow -> s.auto_scroll_follow!==false
- boot.js no-settings fallback: false -> true
- panels.js checkbox render: !!settings.auto_scroll_follow -> !==false
Resolved the config.py + panels.js merge conflicts (kept both the Transparent
Stream setting and auto_scroll_follow). Added test_issue4006_auto_scroll_follow_default.py
pinning the True default across config/boot/panels + the follow-gate references.
The 2 failing assertions pinned the removed implementation (const passes=[0,16,80,180]
setTimeout fan-out + _settleMessageScrollToBottom(true) in scrollToBottom). Updated to
assert the new behavior contract: ResizeObserver on #msgInner + 2s static fallback +
force=false so the observer runs. Behavioral intent (settle survives late markdown
growth; sync write before settle scheduling) preserved.
Codex SHIP-ONLY-WITH-FIXES (3 real issues; Codex+Opus disagreed on #1, stricter wins):
1. CORE — .messages lost overflow-anchor:none, reopening the #1360 (d21c9720) streaming-scroll-anchor regression. Restored it (native anchoring stays OFF; the RO does the settle). Opus had judged this removal acceptable; took Codex's stricter call.
2. SILENT — the ResizeObserver observed #messages (the scroll container, fixed by flex layout, never resizes) instead of #msgInner (.messages-inner, the growing transcript node) → callback would never fire. Now observes #msgInner.
3. SILENT — stale RO callbacks mutated the global _settleRO, which could disconnect a newer active observer after settle re-entry. Now instance-owned: close over const ro, only clear the global when _settleRO===ro.
3 maintainer-review items the contributor hadn't addressed:
1. (blocking) restored .session-list overflow-anchor:none — the PR accidentally reverted the deliberate Firefox sidebar fix (2dfe765b); only the on-topic .messages removal is kept.
2/3. _settleFinalScroll was dead code + the promised 2s static-content safety timeout was missing — wired _settleFinalScroll(token) via a single 2s top-level fallback after _settleRO.observe(el), declared _settleFinalTimer + cleared it in _cancelBottomSettle and at settle re-entry.
Opus final gate caught that the staged re-implementation placed the
window._showThinking===false gate in _worklogReasonNodeFromText, which has
ZERO callers — so live/settled reasoning rows (built by _syncWorklogReasonFromAnchor
and _appendWorklogReason) were never actually hidden, and removeThinking swept
data-worklog-reason-source=reasoning which the real rows (data-worklog-anchor-reason=1)
don't carry. The string-match tests passed against the dead function = green-suite blind spot.
Fix:
- Gate _syncWorklogReasonFromAnchor (live + settled): when _showThinking===false, remove any
existing reasoning row and bail before building.
- Gate _appendWorklogReason (settled rebuild): return null when _showThinking===false.
- removeThinking + the settled-rebuild cleanup now sweep BOTH data-worklog-anchor-reason=1
(the real attribute) and the legacy data-worklog-reason-source=reasoning.
- Re-anchor the tests to assert against the real render functions + the correct attribute.
