Opus was ignoring the valid tag list and generating custom tags like
schema-enrichment-slug-mismatch, which fall through to 'unknown' in
disposition logic. All three prompts (domain, Leo standard, Leo deep)
now explicitly say "do not invent new tags" alongside the valid tag list.

- Domain review → GPT-4o (OpenRouter), Leo STANDARD → Sonnet (OpenRouter),
Leo DEEP → Opus (Claude Max). Two model families = no correlated blind spots.
- Opus reserved for DEEP eval only — protects rate limit for overnight research.
- Review prompts calibrated: require per-criterion evidence, blocking-vs-observation
verdict rules. Moved from 100% rubber-stamp approval to 12% pass rate.
- OpenRouter failures classified as openrouter_failed (not rate_limited) to avoid
spurious 15-min Opus backoff.
- merge.py: pre-check PR state before merge API call (prevents 405 on re-merge).
