Opus advisor review of stage-375 flagged that the protected-bracket set including `<` and `>` caused tables containing comparison operators across adjacent columns to mis-collapse: `| x < 5 | y > 10 |` matched `< ... >` as a bracket pair and stashed the inner pipe, producing one cell instead of two.
Real LLM table output uses angle brackets as comparison operators far more often than as content-grouping pairs, so the safer default is to NOT treat them as a matched pair. Dropped `<` from the opener class and `>` from both closer classes.
Three regression tests added (`TestComparisonOperatorsAcrossColumns` class): `< … >` across columns, `<` alone, `>` alone.
PR #2428's iterative _protectPipes regex introduced two issues we caught during stage assembly:
1. The negated character classes [^)\]}'>] added `'` as a stop character. That breaks cells containing string-literal pipes like `('a'|'b')` (Python type-union examples) — they would still mis-split. Dropped the apostrophe-stop.
2. The literal `}` inside the regex character classes confused the brace-counting extractFunc driver in tests/test_renderer_js_behaviour.py, breaking all 45 existing node-driven renderer tests. Rewrote both brace literals as hex escapes (\\x7b and \\x7d) — semantically identical at the regex-engine level but the JS source carries no bare brace glyph.
Also added tests/test_issue2428_table_pipe_protection.py with 9 regression tests covering single-pipe, multi-pipe-in-brackets, apostrophes-with-pipes, and the KaTeX \$...\$ guard.
Opus advisor on stage-371 caught three issues during pre-release review:
1. RTL salvage missed KaTeX math (display equations + inline LaTeX), diff
blocks, CSV tables (column order must read left-to-right regardless of
chat direction), and .skill-file-path. The first salvage commit only
covered pre/code/kbd/samp/tt and tool-call bodies. Added a second
force-LTR block covering: .katex, .katex-block, .katex-display,
.katex-html, .katex-inline, .diff-block (+children), .csv-table-wrap,
.csv-table (+children), .skill-file-path. Severity: KaTeX is the most
user-visible gap — any user rendering math under RTL would see flipped
equations.
2. Quota chip @media (max-width:1400px) hide rule conflicted at exactly
1400px with the existing @media (min-width:1400px) .messages-inner
rule — chip was hidden AT the wide-desktop boundary where it should
first appear. Changed to (max-width:1399.98px). Visually verified at
1400px: chip now correctly visible there.
3. Dead .icon-btn.provider-quota-chip selector — chip never has icon-btn
class. Removed.
Test added: test_rtl_math_and_tables_stay_ltr (pins the 4 new LTR
surfaces). Also removed dead code in test_rtl_code_blocks_stay_ltr
(unused code_block variable).
Per stage-fix protocol: SHIP-with-followup applied on the stage rather
than the source PR, since #2409 is already merged-into-stage and
nesquena-approved. Stage-371 review-bypass batch path still holds.
PR #2367 added settings_tab_plugins to English only. The locale-parity
tests (test_chinese_locale.py, test_japanese_locale.py, etc.) require
every English key to exist in all 10 other locales. CI failed on 5 of them.
Adds the key to all 10 non-English locales with translations:
- it: Plugin, ja: プラグイン, ru: Плагины, es/de/pt/fr: Plugins (loanword),
zh: 插件, zh-TW: 外掛, ko: 플러그인
Co-authored-by: mccxj <mccxj@users.noreply.github.com>
Adds data-i18n attributes to all settings sidebar menu items
(Conversation, Appearance, Preferences, Plugins, System) so they
respect the user's selected locale.
Also adds missing settings_tab_plugins key to English locale.
Replace the earlier frontend-reset approach with a backend side-channel
approach that preserves the queue (event, data) tuple shape.
Problem (Opus catch):
- Live SSE frames emitted by _sse() in api/streaming.py:2296 carried no
'id:' field. Only journal-replay frames (via _sse_with_id) emitted IDs.
- Frontend's _lastRunJournalSeq cursor stayed at 0 during live streaming.
- Mid-stream error → reconnect-to-replay arrived with after_seq=0.
- Server replayed every journaled event from seq 1.
- assistantText (closure-scoped) had accumulated all live tokens already
→ double-rendered output.
Fix:
- api/config.py: STREAM_LAST_EVENT_ID: dict = {} module-level dict.
- api/streaming.py put(): capture journal event_id, write to
STREAM_LAST_EVENT_ID[stream_id]. Keep queue tuple as (event, data).
- api/routes.py _handle_sse_stream: read STREAM_LAST_EVENT_ID[stream_id]
at emit time, use _sse_with_id when set.
- api/streaming.py finally block: pop STREAM_LAST_EVENT_ID for cleanup.
Why side-channel instead of 3-tuple:
- Earlier attempt (queue tuple → (event, data, event_id)) broke 4 existing
tests: test_cancel_interrupt, test_sprint42, test_sprint51,
test_issue1857_usage_overwrite. These all unpack 'event, data = q.get()'.
- Frontend-reset approach (reset assistantText before replay) broke 3
other tests: test_smooth_text_fade, test_streaming_markdown,
test_streaming_race_fix. _wireSSE must NOT reset accumulators because
legacy reconnect doesn't replay events; only journal-replay does.
Side-channel preserves both invariants:
- Queue contract stays (event, data) — legacy consumers unbroken.
- Frontend accumulators stay alive on _wireSSE — legacy reconnect unbroken.
- Live SSE emits 'id:' so the journal cursor advances correctly.
6 regression tests added in test_stage364_opus_live_sse_event_id.py.
1 existing test (test_run_journal_streaming_static.test_streaming_journals_sse_events_before_queue_delivery) updated to be tuple-shape-agnostic.
Test results:
- Full pytest: 5713 passed, 10 skipped, 1 xfailed, 2 xpassed, 0 failed
- Previously-failing 5 tests: ALL PASS
- 6 new regression tests: ALL PASS
Opus advisor caught that the new run-journal replay path could double-render
when the live stream errors mid-stream:
- Live SSE frames emitted by _sse() in api/streaming.py:2296 carry no 'id:'
field. Only _sse_with_id() (used in _replay_run_journal at routes.py:5853)
emits IDs.
- During live streaming, EventSource.lastEventId stays empty, so the frontend's
_lastRunJournalSeq stays at 0.
- If the server dies mid-stream, the error reconnect handler opens replay with
after_seq=0 — server replays every journaled event from seq 1.
- assistantText accumulator (closure scope in messages.js) carries over from
the live phase. The token handler unconditionally appends d.text. Double-
rendered text.
Fix: reset assistantText, reasoningText, liveReasoningText, segmentStart, and
set _smdReconnect=true before opening the replay EventSource. Next live token
clears assistantBody.innerHTML to match the reset accumulator.
4 regression tests added in test_stage364_opus_replay_doublerender_fix.py.
Revert-fix verification confirms 3/4 tests fail against reverted code.
This is the TWO-LAYER catch in action: agent self-verified the producer→
consumer chain works end-to-end (Step 3 in agent-side-empirical-verification.md
PASSED for #2283), and Opus independently caught a separate frontend coupling
issue. Both checks required and both fire.
