Sanitized runtime evidence for issue 23702
Head: 29ce300674cd6e5ea2b183c8bde4e3ad10a2a4cd
Base: ef92441313
Capture UTC: 2026-10-22T21:15:09.915104+00:00
Trace source: isolated worktree .t3/userdata/logs/server.trace.ndjson
Read-only capture; no tests, browsers, servers launched or stopped.

Timeline supplied by lead: browser disconnected 21:09:42 UTC; watcher restarts 21:09:23 and 21:10:01; new server ready 21:10:08; startup backfill complete 21:10:11.
Restarts and startup backfill excluded from idle periodic claims. Restart shortens uninterrupted patched-process observation; do not describe 21:09:42–21:14:42 as five uninterrupted minutes of one process.

Measured interval: 2026-10-22T21:10:11Z through 2026-10-22T21:14:42Z (271 seconds).
Filter: case-insensitive span name contains ThreadPullRequestServiceV2.synchronize OR branchPullRequest OR listPullRequestsByHead.
Matching spans: 0
Counts: {}
Total completed trace records starting within interval: 854

Final listener check:
LISTEN 0      511    127.0.0.1:14162 0.0.0.0:* users:(("node-MainThread",pid=1507623,fd=23))
Final established/other TCP sockets involving port 14162:
ESTAB 0      0      127.0.0.1:48672 127.0.0.1:14162 users:(("node-MainThread",pid=1502416,fd=33))

Initial capture 21:11:51 UTC likewise showed LISTEN pid=1507623 and no TCP sockets involving port 14162.

Reported deterministic test evidence (not executed by this capture agent):
Red commit 1e1b2b9ea9: does not sweep branch pull requests while no client is connected; after TestClock.adjust ten minutes expected [] and got 10 calls.
Patched head: all 6 focused tests green (reported by test author).

Visual matrix: empty, 0/0. No visual differences or platform-specific changes.
Foreground positive control is separate, to be produced by lead after idle capture.
No shared quota delta attributed to this change.
Sanitization: only span timestamps, names, success markers, aggregate counts and local listener metadata retained; no SQL, payloads, tokens, auth, or conversation content.

FRICTION evidence | watcher restarts interrupt initial idle window | count only post-startup 21:10:11 onward and disclose 271-second uninterrupted interval.
