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.
fix: clarify cancelled chat turn status (Jordan-SkyLF)
Conflict resolution on api/streaming.py:4549-4567 (the cancel-handler
ownership guard). Both this PR and the already-shipped PR #2136 add a
guard at the same site against stale stream writebacks, from different
angles:
- PR #2136 (HEAD): _stream_writeback_is_current(_cs, stream_id) — strictly
dominates by checking the active_stream_id token equality.
- PR #2151: 'worker won the race' check via (active_stream_id != stream_id
and not pending_user_message), with _emit_cancel_event = False to suppress
the terminal cancel event.
Resolution merges both: keep #2136's strictly-stronger condition for skip
detection, and adopt #2151's _emit_cancel_event = False semantic so the
cancel event isn't emitted in addition to skipping the writeback (when
client may have already received the successful done payload).
55/55 tests pass across cancelled-turn-status + stale-stream-writeback +
the four cancel/data-loss sibling test files.
