- claude process: run stdout/stderr reads without ct; rely on
kill-on-cancel closing the pipes to unblock them — previously
ReadLineAsync(ct) could hang, stalling task slots and shutdown
- task runner: terminal db writes (task_runs, MarkDone, MarkFailed,
SetLogPath) now use CancellationToken.None; RunOnceAsync catches
OCE and finalizes the run row so ContinueAsync can resume
- task repository: GetNextQueuedAgentTaskAsync is now a single
UPDATE ... RETURNING statement — closes TOCTOU window where two
loop iterations could dispatch the same queued task
- queue service: dispose CancellationTokenSource in slot-completion
ContinueWith to stop leaking wait handles
- git service: register ct.Kill(processTree), drain reads without ct,
always reap via WaitForExitAsync(None) — no more git zombies on
cancelled worktree ops
- worktree manager: branch name uses full task id (dashes stripped)
instead of 8-char prefix, eliminating collision risk
