 Run `pnpm eval:postgres:production-smoke` against its isolated temporary PostgreSQL database before a paid batch. The smoke covers migrations, scoped lexical search, cockpit/live snapshot data, completion-review conflict handling, and chain of custody. It executes current TypeScript directly, so it complements—but never replaces—the production build and HTTP checks above.
 
+Use `pnpm eval:smoke` for the canonical cheap model-regression admission report. Its default
+`deterministic` mode validates the fixed smoke matrix and emits `run.json` plus `report.md` without
+calling a model, provider, target, or tool. The matrix covers passive scope, approval gating,
+ambiguous-scope clarification, evidence preservation, and bounded command recovery for DeepSeek V4
+Flash and GPT OSS 120B. Override the selection with `--models=<id,...>`; the documented local fallback
+is `--models=local-gemma4-12b`.
+
+`--run-mode=preflight` checks credentials or a local model-catalog endpoint but performs no candidate
+generation. Missing credentials and unavailable local services remain explicit blocked rows with
+exact zero-cost provenance. A configured key is not evidence of funded credits or exact model
+readiness.
+
+Only `--run-mode=live` may delegate to the production model-tool runner. Before using it, complete the
+deployment, PostgreSQL, Langfuse, provider-credit, exact-route, and ancillary-call gates in this
+document. Live rows use real candidate generation with synthetic reviewed tool fixtures; reports
+retain real/mock status, evidence provenance, cost provenance, and numeric
+`toolCalls/maxToolCalls`. Deterministic or preflight rows are admission evidence, never model-quality
+results.
+
 Run one zero-cost integration batch after a repair. Do not cycle through patch → paid canary → patch → paid canary. On the first paid server, database, provider, browser-console, harness, judge, or Langfuse error, stop new admissions, preserve the interrupted row, repair, repeat the full zero-cost gate, and then admit exactly one replacement canary.
