+Set `OPENROUTER_API_KEY` in the environment. `OPENROUTER_MODEL` optionally
+changes the default `openai/gpt-oss-120b:nitro`. The example host invokes curl;
+the library retains its pure boundary. Credentials pass on curl stdin and are
+excluded from artifacts. Every model request, response, candidate and lineage
+record is saved below the chosen output directory, which must be different
+for each run.

+The incumbent deliberately contains a status-filter bug. The editor sees that
+training feedback, but not the three held-out invoice inputs. The host checks
+numeric answers exactly, requires all three to pass, and rejects a deliberately
+broken prompt after evaluating it with the same live model. It also requests a telemetry mutation and checks a contamination canary.
+A provider refusal is retained explicitly; the host then tests the requested
+mutation fixture itself and records its origin. This is a small
+integration smoke test, not evidence of general self-improvement on SWE tasks.
+
+Use the resulting `accepted-package.json` with the adapter's
+[live language example](../../tinyhivemind-openhuman/examples/README.md) to
+exercise native tool completion and registration from the lowered package.
+
+Failed provider calls retain redacted response bodies in `response-N.error`
+and include a bounded, redacted stderr excerpt in the returned error. Run the
+offline regression with `cargo test -p tinyhivemind-lang --example live_self_edit`.
