Opus pre-release advisor caught 4 issues in stage-255 (#1390 + #1405):
1. MUST-FIX: api/rollback.py path-traversal — _checkpoint_root() / ws_hash /
checkpoint did NOT normalize Path() / "../escape", so an authenticated
caller could read or restore from another allowlisted workspace via
../<other-ws-hash>/<sha>. New _validate_checkpoint_id() regex-guards
with ^[A-Za-z0-9_-][A-Za-z0-9_.-]{0,63}$ and rejects . and .. literals.
Both get_checkpoint_diff and restore_checkpoint validate.
2. SHOULD-FIX: redact_session_data perf cliff — the new api_redact_enabled
toggle in #1405 called uncached load_settings() per string, recursed
across messages[] and tool_calls[]. For a 50-message session: hundreds
of disk reads per /api/session response. Now read once at the top and
thread _enabled through via private kwarg.
3. SHOULD-FIX: voice-mode wrong-session TTS — the patched autoReadLastAssistant
fires globally; if the user navigated to a different session between
sending and stream completion, TTS would speak the wrong session\\s reply.
New _voiceModeThinkingSid closure captures S.session.session_id at
thinking-time; _speakResponse bails to _startListening() on mismatch.
4. NIT: rollback._inspect_checkpoint had bare Exception in the except tuple
alongside specific catches, swallowing everything. Now (TimeoutExpired,
OSError) only.
6 regression tests in test_v050255_opus_followups.py. Full suite: 3587 passed,
2 skipped, 3 xpassed.
- Point 4 (security): _resolve_workspace now validates against known workspaces
from workspaces.json to prevent arbitrary path write via restore endpoint
- Point 5 (voice mode): bail out of voice mode on not-allowed, service-not-allowed,
and audio-capture errors instead of infinite retry loop
- Point 1 (locale coverage): added ~40 new English keys as placeholders with
TODO:translate comments in zh, zh-Hant, ko, ru, es, de, pt locales
- Point 2 (test fix): tightened test regex to anchor on branch-indicator class
to avoid collision with _sessionLineageKey helper
- Point 3 (test fix): accept both inline and parentEl variable forms for
body.appendChild pattern in pinned indicator test
All 6 previously failing tests now pass.
