Two silent paths in substantive_fix_cycle masked a 13-day stall:
1. Filter strips all candidates → return 0,0 with no log. With LIMIT 3
ordered created_at ASC, if the oldest 3 have no fixer-actionable tags
(e.g. eval_issues=[] from leo:skipped+domain:request_changes), the
cycle silently picks the same head-of-line every tick.
2. _fix_pr early-returns logged at DEBUG only — invisible without
fleet-wide DEBUG. Skip reasons (no_claim_files, no_review_comments,
not_open lock, worktree_failed, etc.) never surfaced in journalctl.
Patch: log skipped candidate eval_issues when no actionable rows
found (path 1); promote DEBUG→INFO for per-PR skip reasons (path 2).
Zero behavior change — observability only.
Diagnosis context: 98 PRs stuck >3d, last successful substantive_fixer
event 2026-04-24. Need journal evidence to choose between (a) one-line
fix to the cycle, (b) larger _fix_pr regression. (Ship Step 2 directive.)
Fix 4 Forgejo ghost PR bugs flagged by Ganymede:
- fixer.py GC close: DB update ran outside try/except, closing DB even on Forgejo failure
- substantive_fixer.py droppable: NO Forgejo close at all
- substantive_fixer.py auto-enrichment: DB update before Forgejo (reversed order)
- substantive_fixer.py close_and_reextract: replace manual Forgejo+DB with close_pr()
Add start_fixing() and reset_for_reeval() to pr_state.py:
- start_fixing: atomic claim + fix_attempts increment in one statement
- reset_for_reeval: clears all eval state for re-evaluation after fix
Also fixes stale line number comment in merge.py (Ganymede nit).

Gate 3 in batch-extract-50.sh: query pipeline.db for closed PRs before
re-extracting. Sources with >=3 closed PRs are skipped (zombie protection).
Cost tracking: openrouter_call() now returns (text, usage) tuple with
prompt_tokens and completion_tokens from the OpenRouter API response.
All callers updated to unpack and pass tokens to costs.record_usage().
Added missing triage cost recording. Fixed batch domain review recording
cost once per batch instead of once per PR.
