 - The 502 live run at `dabd9e2` was PATH NOT OBSERVABLE ON FAILURE: provider path survived provider errors but not successful-provider/later-validation failures.
 - Successful provider results now retain their factual attempted path through later reconstruction-validation failure diagnostics. This corrects only that observability seam; the next unknown remains one real `/api/cases/start` call establishing `/api/chat` versus `/api/generate`.

+## Zod 4 migration
+
+- Zod upgraded from 3.25.76 to 4.5.4. Reconstruction and direct Zod-owner suites pass, and native `z.toJSONSchema()` converts the production reconstruction schema with required closed enum constraints.
+- Zod-3-specific error-message assertions are version-independent while retaining semantic validation evidence. Production schema semantics are unchanged and no third-party JSON-schema conversion dependency was added.
+- Next unknown: whether Ollama/Qwen accepts and obeys the generated schema through `/api/chat` format.
