Recovery: `gitreins task complete` killed between status flip and tier2 verdict

Problem class: gitreins-tier2-judge-midrun-kill-recovery Applies to: gitreins co-harness v0.12.x, main 813996b, Python repo (terminal-jail) Symptom: gitreins task list shows the task complete, but there is no .gitreins/history/<date>/<hash>/verdict.json; usage.jsonl has two tier2 token entries (the completed guard run + the killed judge run); the board row is still pending.

1. Root cause

gitreins task complete is two operations with a durable write in between, and only the first is guarded by the task record:

# gitreins/cli.py :: cmd_task_complete
task = tm.complete(args.id, force=force)   # <- writes status=complete + completed_at to .gitreins/tasks.yaml
print(f"Completed: {task.id} → {task.status}")

print("\nEvaluating...")
llm = LLMClient()
judge = Judge(llm, workdir)
result = judge.evaluate_task(task)         # <- long: Tier 1 guards + Tier 2 agentic eval (LLM)
print(result.summary)

_persist_result(workdir, task, result)     # <- writes .gitreins/history/<date>/<hash>/verdict.json

TaskManager.complete() (engine/task_manager.py) flushes the task to YAML immediately. The verdict is only written after the entire guard + tier2 run finishes, by VerdictPersister.persist() (engine/persist.py), where

entry_dir = <workdir>/.gitreins/history/<UTC date>/<sha256(task_id:evaluated_at)[:8]>/verdict.json

If the foreman process (or the tool timeout wrapping it) dies after the YAML write and before _persist_result, the repository is left in a split-brain state:

Artifact	State
`.gitreins/tasks.yaml`	`status: complete`, `completed_at: <ts>` ✅
`usage.jsonl`	tier2 tokens already spent (1 completed guard run + 1 killed judge run)
`.gitreins/history/<date>/.../verdict.json`	missing ❌
board row	still pending (lifecycle close is keyed on the verdict)

The lifecycle/board is keyed on the verdict, so a task that is "complete" in YAML but has no verdict is not closeable. Re-running gitreins task complete does not fix this: the status flip is already durable, and depending on version/harness the second call either aborts or (as in 0.12.0) silently re-runs the whole guard+tier2 pipeline and can write a duplicate verdict. The missing piece is only the verdict, so re-run only the judge.

Secondary race (know it exists)

engine/job_store.py + cli.py::_cmd_judge_worker save the job record as complete before calling _persist_result:

job["status"] = "complete"
job["finished_at"] = time.time()
save_job(job)                # durable "complete"...
_persist_result(wd, task, result)   # ...but verdict not yet written

A kill in that window produces a complete job with no verdict. Re-running the worker for that job id is a no-op (if job["status"] != "running": sys.exit(0)), so recovery must dispatch a fresh judge --async (new job id), not re-run the old one.

2. Exact fix (runbook)

Run from the repo root. Replace TASK_ID (e.g. T1).

Step 0 — establish the signature

TASK_ID=T1

# task is complete-flipped
grep -A5 "id: ${TASK_ID}$" .gitreins/tasks.yaml

# there is no verdict for it yet
find .gitreins/history -name verdict.json 2>/dev/null | grep -c . || true

# the duplicate tier2 spend
grep -c '"tier": *"tier2"\|tier2' usage.jsonl 2>/dev/null || true

Step 1 — do not call `gitreins task complete` again

The status flip already happened. A second task complete re-runs guards + tier2 (extra tokens) and can duplicate the verdict. Re-run the judge instead.

Step 2 — confirm there is no live judge job

The disk-backed job store is ~/.local/share/gitreins/jobs/ (overridable with GITREINS_JOB_DIR). In 0.12.x the CLI judge --status needs a job id; there is no "list" verb. Enumerate and check pid liveness:

python - <<'PY'
import glob, json, os
d = os.environ.get("GITREINS_JOB_DIR", os.path.expanduser("~/.local/share/gitreins/jobs"))
def alive(pid):
    if not isinstance(pid, int) or pid <= 0:
        return False
    try:
        os.kill(pid, 0); return True
    except ProcessLookupError:
        return False
    except PermissionError:
        return True
live = []
for p in sorted(glob.glob(os.path.join(d, "job-*.json"))):
    j = json.load(open(p))
    if j.get("status") == "running" and alive(j.get("pid")):
        live.append((j["id"], j.get("task_id"), j.get("pid")))
print("live jobs:", live or "NONE")
PY

If you know a job id from the killed run's Async job dispatched: <id> line, poll it:

gitreins judge --status <job-id>   # exit 0 complete / 1 error / 2 running

Do not start the recovery while a live judge for the same task is still running.

Step 3 — re-run only the judge, asynchronously (the fix)

gitreins judge "$TASK_ID" --async
# -> Async job dispatched: job-<hex>
#      poll:    gitreins judge --status job-<hex>

The async worker loads the already-complete task, runs Tier 1 + Tier 2, writes the job result, and then persists the verdict exactly like a synchronous run (_cmd_judge_worker → _persist_result). It survives the foreman exiting.

Step 4 — poll to completion

JOB=job-<hex>
until gitreins judge --status "$JOB"; do
  rc=$?
  [ "$rc" -eq 1 ] && { echo "judge ERROR (see $(gitreins judge --status "$JOB" 2>&1 | sed -n 's/^Log: //p'))"; exit 1; }
  sleep 5
done
# exit 0 == PASS/complete ; exit 2 == still running ; exit 1 == error/not found

If --status ends in error, read the worker log at $GITREINS_JOB_DIR/<job-id>.log and dispatch a fresh judge --async after clearing the cause. If a completed job has no verdict on disk (secondary race), do not re-run the same job id — it is a no-op; dispatch a fresh judge --async.

Step 5 — confirm the verdict exists

# filesystem storage -> file is on disk
find .gitreins/history -name verdict.json -newermt '-1 hour' -print -exec cat {} \;

# git storage (default) -> verdict is committed on the `gitreins` orphan branch
git ls-tree -r --name-only gitreins -- .gitreins/history | grep verdict.json
gitreins report | head

With the default history.storage: "git", persist() writes the entry under .gitreins/history/<date>/<hash>/ and then commits it to the gitreins branch; the working-tree copy can disappear on checkout, so use gitreins report / git show as the source of truth. With storage: "filesystem", the file stays exactly at .gitreins/history/<date>/<hash>/verdict.json.

Step 6 — reputation hygiene before closing the lifecycle

The judge's RED-proof can rewrite tracked VFS/graph state. Every judge run (sync or async) must be followed by:

git checkout -- .vfs/graph/edges.jsonl
git diff HEAD --stat        # must be empty before the board commit

Then close the lifecycle normally (board row → board commit → push). Do not commit with a dirty judge-authored diff.

3. Hardening (optional, prevents recurrence)

Make task complete idempotent w.r.t. the verdict. In cmd_task_complete, before evaluating:

python from engine.persist import VerdictPersister if task.status == "complete" and VerdictPersister(workdir).list_verdicts(task_id=task.id): print(f"Already complete with a verdict: {task.id} — nothing to do") return if task.status == "complete": print(f"Task {task.id} is already complete but has no verdict.") print(f"Recover with: gitreins judge {task.id} --async") sys.exit(2)

Persist before marking the job complete. In _cmd_judge_worker, call _persist_result(...) before job["status"] = "complete"; save_job(job), so a kill never leaves a complete job without a verdict.
Wrap the long Tier 2 phase in --async. The harness should always call gitreins task complete (or its judge phase) under gitreins judge <ID> --async and poll, rather than running a foreground judge that a tool timeout can kill at an arbitrary point.

4. Verification (reproduced in this environment, gitreins 0.12.0)

A scratch repo was driven through the exact failure and recovery.

Reproduce the split-brain state (kill task complete mid-run; here Tier 1's pytest sleeps, giving a kill window after the YAML flip):

$ gitreins task complete T1 &   # killed -9 ~5s later
$ cat .gitreins/tasks.yaml
  status: complete
  completed_at: '2026-09-21T07:34:57.007205+00:00'
$ find .gitreins/history -name verdict.json
  (none)
$ gitreins task list
  ● T1                   Demo complete task

Recover with only the judge:

$ gitreins judge T1 --async
Async job dispatched: job-724baa2beebc47668688150c01e9664a
  task:    T1
$ gitreins judge --status job-724baa2beebc47668688150c01e9664a
Status:   running      -> exit 2
...
$ gitreins judge --status job-724baa2beebc47668688150c01e9664a
Status:   complete
Result:   PASS ✓
  ✓ First criterion: verified in README
                                           -> exit 0

Verdict written (filesystem storage, matching the on-disk signature in the report):

$ find .gitreins/history -name verdict.json
.gitreins/history/2026-09-21/02924e8c/verdict.json
$ python -c "import json;d=json.load(open('.gitreins/history/2026-09-21/02924e8c/verdict.json'));print(d['task_id'], d['passed'])"
T2 True

Verdict written (default git storage):

$ git ls-tree -r --name-only gitreins -- .gitreins/history
.gitreins/history/2026-09-21/bfc80ff4/verdict.json
$ gitreins report
  ✓ T1                       2026-09-21
     Demo complete task
Storage: git (.../.gitreins/history)   Total entries: 1

Exit-code contract confirmed: judge --status returned 2 while running, 0 on complete, and 1 for a missing/errored job. Re-running judge --run-job <completed-job> printed already complete — nothing to do (exit 0), confirming the secondary race must be recovered with a fresh --async dispatch.

Anti-pattern confirmed: a second gitreins task complete T2 did not error in 0.12.0 — it re-ran the full guard+tier2 pipeline and produced a second verdict.json. This is why the recovery must re-run only the judge.

Recovery: `gitreins task complete` killed between status flip and tier2 verdict

1. Root cause

gitreins task complete is two operations with a durable write in between, and only the first is guarded by the task record:

# gitreins/cli.py :: cmd_task_complete
task = tm.complete(args.id, force=force)   # <- writes status=complete + completed_at to .gitreins/tasks.yaml
print(f"Completed: {task.id} → {task.status}")

print("\nEvaluating...")
llm = LLMClient()
judge = Judge(llm, workdir)
result = judge.evaluate_task(task)         # <- long: Tier 1 guards + Tier 2 agentic eval (LLM)
print(result.summary)

_persist_result(workdir, task, result)     # <- writes .gitreins/history/<date>/<hash>/verdict.json

entry_dir = <workdir>/.gitreins/history/<UTC date>/<sha256(task_id:evaluated_at)[:8]>/verdict.json

If the foreman process (or the tool timeout wrapping it) dies after the YAML write and before _persist_result, the repository is left in a split-brain state:

Artifact	State
`.gitreins/tasks.yaml`	`status: complete`, `completed_at: <ts>` ✅
`usage.jsonl`	tier2 tokens already spent (1 completed guard run + 1 killed judge run)
`.gitreins/history/<date>/.../verdict.json`	missing ❌
board row	still pending (lifecycle close is keyed on the verdict)

Secondary race (know it exists)

engine/job_store.py + cli.py::_cmd_judge_worker save the job record as complete before calling _persist_result:

job["status"] = "complete"
job["finished_at"] = time.time()
save_job(job)                # durable "complete"...
_persist_result(wd, task, result)   # ...but verdict not yet written

2. Exact fix (runbook)

Run from the repo root. Replace TASK_ID (e.g. T1).

Step 0 — establish the signature

TASK_ID=T1

# task is complete-flipped
grep -A5 "id: ${TASK_ID}$" .gitreins/tasks.yaml

# there is no verdict for it yet
find .gitreins/history -name verdict.json 2>/dev/null | grep -c . || true

# the duplicate tier2 spend
grep -c '"tier": *"tier2"\|tier2' usage.jsonl 2>/dev/null || true

Step 1 — do not call `gitreins task complete` again

The status flip already happened. A second task complete re-runs guards + tier2 (extra tokens) and can duplicate the verdict. Re-run the judge instead.

Step 2 — confirm there is no live judge job

python - <<'PY'
import glob, json, os
d = os.environ.get("GITREINS_JOB_DIR", os.path.expanduser("~/.local/share/gitreins/jobs"))
def alive(pid):
    if not isinstance(pid, int) or pid <= 0:
        return False
    try:
        os.kill(pid, 0); return True
    except ProcessLookupError:
        return False
    except PermissionError:
        return True
live = []
for p in sorted(glob.glob(os.path.join(d, "job-*.json"))):
    j = json.load(open(p))
    if j.get("status") == "running" and alive(j.get("pid")):
        live.append((j["id"], j.get("task_id"), j.get("pid")))
print("live jobs:", live or "NONE")
PY

If you know a job id from the killed run's Async job dispatched: <id> line, poll it:

gitreins judge --status <job-id>   # exit 0 complete / 1 error / 2 running

Do not start the recovery while a live judge for the same task is still running.

Step 3 — re-run only the judge, asynchronously (the fix)

gitreins judge "$TASK_ID" --async
# -> Async job dispatched: job-<hex>
#      poll:    gitreins judge --status job-<hex>

Step 4 — poll to completion

JOB=job-<hex>
until gitreins judge --status "$JOB"; do
  rc=$?
  [ "$rc" -eq 1 ] && { echo "judge ERROR (see $(gitreins judge --status "$JOB" 2>&1 | sed -n 's/^Log: //p'))"; exit 1; }
  sleep 5
done
# exit 0 == PASS/complete ; exit 2 == still running ; exit 1 == error/not found

Step 5 — confirm the verdict exists

# filesystem storage -> file is on disk
find .gitreins/history -name verdict.json -newermt '-1 hour' -print -exec cat {} \;

# git storage (default) -> verdict is committed on the `gitreins` orphan branch
git ls-tree -r --name-only gitreins -- .gitreins/history | grep verdict.json
gitreins report | head

With the default history.storage: "git", persist() writes the entry under .gitreins/history/<date>/<hash>/ and then commits it to the gitreins branch; the working-tree copy can disappear on checkout, so use gitreins report / git show as the source of truth. With storage: "filesystem", the file stays exactly at .gitreins/history/<date>/<hash>/verdict.json.

The judge's RED-proof can rewrite tracked VFS/graph state. Every judge run (sync or async) must be followed by:

git checkout -- .vfs/graph/edges.jsonl
