-Boatstack is a generated content distribution. Propose changes to workflow semantics, templates, evidence rules, or generated presentation in [Intelligence Flow](https://github.com/operatorstack/intelligence-flow/tree/7d6ae9e63d7a6106ae7bf6a2a26e1257c455932b/labs/12-product-engineering-loop).
+Boatstack is a generated content distribution. Propose changes to workflow semantics, templates, evidence rules, or generated presentation in [Intelligence Flow](https://github.com/operatorstack/intelligence-flow/tree/b5f5cd69a44fdba533c0b821c55eca08c7fd6b4f/labs/12-product-engineering-loop).
 
 The Boatstack repository receives product/runtime changes through a generated pull request. Review the PR's `UPSTREAM.json`, tests, adapter diff, and context-size change; do not hand-edit generated output on `main`. `.github/workflows` is the exception: it is Boatstack's executable control plane, excluded from scheduled projection and changed only through a separate manually reviewed Boatstack PR.

Move internal operations (`check-plan`, `record-approval`, `activate-plan`), hashes, paths, tables, receipts, locks, and raw output into **Technical details**. **Exactly one primary action:** end with the action that advances or unblocks the current state; a secondary option gets one short sentence.

 The evidence supports specific failure mechanisms and guardrails. It does not establish that Boatstack is optimal, that control-theory notation proves software quality, or that one workflow dominates every team. Those are evaluation questions, so the distribution preserves measurements, provenance, gaps, and negative results.
