executors.<x>.tier_defaults maps a model to the tier used when no label sets one;
a tier:<name> label sets it explicitly and tier:none drops the tier argument.
- A run whose item leaves In Progress is killed, gets a [worker] cancel comment,
frees its terminal slot and serialize group and keeps its thread id; if the
kill fails the slot stays taken and the cancel is retried next tick.
- Transient retries are the same logical round: they do not count toward
max_rounds_per_thread and do not trigger a max-rounds rebuild.
- New project setting max_progress_rounds (default 12): after that many
consecutive [progress] rounds the item goes to Waiting (answerer) with a note.
- retry/rebuild markers are consumed only after the run launched, so a failed
start no longer leaves an In Progress item that is never picked again; a
rebuild is no longer reported as a retry.
- State is saved after every finished round and every launched run.
- Failure classification: transient patterns only look at the tail, and an
exit-0 failure is logic (never retried) unless the tail shows a transient error.
- First-line tag: tolerate BOM and a leading code fence / rule line.
- Start comment notes when a handoff summary was attached.
- Executors and relay helpers get an environment without any configured
Plane token / webhook secret (design 8: executors hold no Plane credentials).
- Windows runner: Set-Location -LiteralPath, and a failed cd writes exit=97
instead of running the agent in the wrong directory.
- schtasks launch: escape apostrophes and pass the script path as \"...\" so
paths with spaces survive PowerShell 5.1 native quoting.
- State and heartbeat files are written temp + fsync + rename.
- Tests for the above plus codex run/resume command shapes and unique run dirs.
One tick polls in-flight runs, posts results, classifies the first line and
moves state/assignee; failures get a structured note with transient retry and
backoff, timeouts are killed and handed over, resume failures and long threads
rebuild with a handoff summary. Then the lowest Todo items are dispatched within
terminal concurrency and serialize groups, and a heartbeat is written.
CLI: tick, new, show, comment, state, assign, smoke, check-config.
