Fix playbook context delivery and guardrail output leaks

 For interrupted local inference, reuse the worker's explicit `--resume` only when it accepts the original incomplete JSONL prefix and exact plan/runtime/package fingerprints. Preserve all prior rows, including errors. The worker requires a hash-bound attempt journal ending at a completed case, appends only not-yet-started cases and records its actual resumption. An in-flight or unknown attempt blocks recovery. Use `--max-cases N` for an explicit boundary checkpoint; exit 4 remains incomplete evidence. Changed or legacy runtime evidence must remain separate; never edit a raw output or its plan hash to make recovery pass. Run the deterministic recovery regressions with `python3 tests/worker_resume_test.py`.
 
 When diagnosing a partial pilot, use the existing evaluation command's `diagnose NEW_JSON --workdir DIR` mode. Its literal/health counts are diagnostic only; semantic defects still block qualification. Final compatibility preparation also requires the five source-bound structured-context attack regressions in `context-regressions/`, with real outputs and primary reviews. The preparation SQL inserts only model-scoped compatibility evidence; publication flags and the actual reviewer are set exclusively through the authenticated admin flow.

+For local playbook gateway changes, retain `tests/playbook-gateway.test.ts` in `test:all`. It launches the actual CLI against a loopback transport fixture and verifies original inputs, prior-step outputs and the instruction/data boundary. Empty or truncated generation must stop before downstream steps. Run `node --experimental-strip-types --test tests/playbook-gateway.test.ts` for the tight regression loop. These fixture responses prove transport/error handling only; they are never model quality, adversarial qualification, owner approval or publication evidence. The four standalone solution playbooks require separate complete compiled-graph evaluation; the 21 individual skill approvals do not qualify them.

+# Solution playbook runtime qualification
+
+The four standalone `solution-*` playbooks remain unqualified. Their solution
+pages and the approval of 21 individual skills do not approve execution of these
+compiled workflows. No production publication is authorized by this document.
+
+The gateway CLI previously dropped `RunContext.inputs` and `RunContext.steps`.
+The real CLI regression reproduced that omission and acceptance of both empty and
+truncated outputs. The adapter now sends instruction text as a system message and
+original inputs plus prior outputs as untrusted JSON data. It requires a nonempty
+string with `finish_reason: stop` before the runtime can continue.
+
+Run the reusable transport regression without model calls:
+
+```sh
+node --experimental-strip-types --test tests/playbook-gateway.test.ts
+npm run check:project
+```
+
+The loopback server supplies fixture responses only. These results cannot approve
+model behavior, injection resistance, calculated business answers or completion
+of a workflow. A successful runtime status means its configured steps completed;
+it is not controller approval, a signed document, posting, payment or deployment.
+
+Next qualification must freeze the four actual YAML sources, compiled runtime and
+gateway adapter hashes, case inputs, original numeric and severity gates, model
+revision, installed SDKs and generation settings before inference. Execute every
+instruction in the actual compiled graph with original sources and prior outputs.
+Retain every raw step response, finish reason, actual model and usage; reject
+errors, truncation, missing evidence and invented external actions. Review valid
+business calculations and each source-injection and authority attack against the
+frozen expectations. Do not repair evaluated responses or transfer approvals
+from the individual skills. A pilot remains a pilot.
+
+Use the existing cached 9B model only after verifying its recorded fingerprints.
+Bind the server to loopback, disable downloads and live tools, and retain its
+process and shutdown evidence. The old `redact-route-generate-v1` qualification
+belongs to the individual skill runner; it does not cover this different graph.
+Any successful new qualification must name its exact runtime/model scope and
+immutable package version. Keep failed histories. Publish only via the existing
+administrator and adversarial approval gates after complete evidence passes.
