The validator pattern-matches *TOKEN* as credential-shaped and rejected
both contexts, failing every task on the new harnesses. The env var name
is fixed by Claude Code, so deliver the thinking budget via the
settings.json env map in init.sh instead (jq-merge preserves apiKeyHelper
from the minimax/oauth layer).

Probes 7-9 (2026-05-08) all "succeeded" but with empty diffs because
AR-14a fell back to fork main: "WARNING: /workspace/reference/main/.git
not found; using fork main (may be stale)". The reference clone python
loop printed "Cloning git@..." but never "Cloned main successfully" —
no error visible either.
Most likely cause: full-history clone (post-3087ad7) is hitting some
silent failure mode (auth, fs perms, OOM, timeout). With capture_output=True
the git clone's own output was hidden.
Add explicit logging:
- python3 -u (unbuffered stdout)
- pre-loop "reference_branches loop: N entries"
- post-clone "clone returncode=N"
- always-print stdout (last 1KB) and stderr (last 1KB) from subprocess
- explicit chmod return code check
- post-clone .git existence assertion
Next probe will tell us EXACTLY what's failing.

Probe 7 (2026-05-08) finally surfaced the actual push error:
! [remote rejected] HEAD -> task-9dc266b5 (shallow update not allowed)
Cause: REFERENCE_BRANCHES handler clones with --depth 1, AR-14a then
fetches upstream-ref --depth 1. The agent's task branch is a single
commit on top of a single shallow commit — no ancestry visible. Gitea
rejects shallow pushes server-side.
Fix:
- Reference clone drops --depth 1 (full history)
- AR-14a fetch upstream-ref drops --depth 1 (full fetch from local-path)
- Cost: a few extra MB per task on tmpfs/PVC. Acceptable.
This unblocks AR-14a's upstream-seeding for the dogfood pipeline. The
agent's branch now has the full upstream history visible to gitea.

Three load-bearing fixes for the airouter dogfood pipeline, derived from
the 2026-05-08 batch-3 dogfood postmortem (gotchas-airouter.md items 27-30):
1. agent-repo/v1/init.sh — seed fresh task branches from
/workspace/reference/main/ (the upstream clone) rather than the agent
repo's stale main. This was THE killer for batch 3: the
agent-runtimes-agents fork has been frozen at 2026-05-04 since the
"Fork cleanup" PR, so every agent started from old state, missing
recent test files and the M16/M22 scripts to delete. The fork remains
the push remote (so finalize.sh works); only the working-tree seed
moves to the upstream reference. Falls back to fork main when the
reference clone isn't available (preserves legacy behavior). Tagged
AR-14a.
2. requires_labels on contexts/composites — airouter context + both
airouter composites declare requires_labels: [airouter] so the
dispatcher's _collect_supported_harnesses (with the matching agent-
runtimes change) advertises them only on dispatchers carrying the
airouter label. Stops the main dispatcher from claiming airouter-
labeled tasks and dying at init time. Composites that wrap label-
restricted contexts MUST redeclare their own requires_labels — no
auto-traversal of layers (kept simple).
3. agent-repo/v1/finalize.sh — AR-21 diff-against-upstream verification.
New env-var protocol:
- AGENT_EXPECTED_CHANGED_FILES (comma-separated paths that MUST
appear in `git diff <ref/main>..HEAD`)
- AGENT_FORBIDDEN_CHANGED_FILES (paths that MUST NOT appear)
finalize.sh fails the task (exit 1) if either invariant is violated;
the branch is still pushed for forensics so the operator can inspect.
Catches BOTH the false-success mode (item 30 — agent reports succeeded
but never changed the target file) AND the destructive-Write mode
(item 21 — task 4a2f2988 stripped 9 unrelated functions). Also writes
diff_verified, diff_mismatch, diff_changed_files into ci_metadata.json.
CRS pulls all three on next CP poll — no agent-runtimes image rebuild
needed for the framework parts. The matching dispatcher poller filter
ships in agent-runtimes (separate commit).
