ROOT FIX (product bug): POST /api/settings never invalidated the session-list
cache, so toggling show_cli_sessions/show_cron_sessions could serve a stale
sidebar for up to the cache TTL when the settings-file mtime stamp collided with
a cached entry. The handler now clears the cache directly on those toggles. This
is also the root cause of the recurring test_gateway_sync CI flake (session
absent from /api/sessions right after the visibility toggle).
DEFENSE-IN-DEPTH: cleanup_test_sessions fixture now resets show_cli_sessions to
default BEFORE each test too, not only in teardown.
FLAKE FIX (test infra): bump 31 node-subprocess correctness-harness timeouts from
10s -> 30s across 23 test files. Node spawn + V8 warmup under parallel CI shard
load can exceed 10s, causing TimeoutExpired flakes (e.g. test_1325 on #4445).
Only real node subprocess.run() sites changed — mock signatures, HTTP urlopen,
and deliberate timeout-behavior tests (test_api_timeout, timeout=0/1/2) untouched.
Constituent PRs:
- #1768 (@franksong2702) serialize Anthropic env fallback reads. Closes#1736.
- #1778 (@Michaelyklam) preserve CLI session tool metadata. Closes#1772.
- #1779 (@Michaelyklam) reset model picker on session switch. Closes#1771.
AUTO-FIX: Opus stage-310 caught a regression in the new !hasSessionModel
branch — it dropped the deferModelCorrection guard that the parallel
else-branch keeps. Fired spurious /api/session/update POSTs against
imported/read-only CLI sessions whose model field reads 'unknown' (the
exact surface #1778 introduces in this same release). Wrapped the new
branch's _persistSessionModelCorrection call + state mutation in
if(!deferModelCorrection). Added test_sync_topbar_does_not_persist_correction_while_model_resolution_deferred
regression test covering both empty and 'unknown' fast-path interaction.
