 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.

Repository artifacts, managed delivery state, gate receipts, and the recorded PR identity are evidence; conversation, terminal, worktree, and process observations are context only.

If state is ambiguous, stale, or invalid, name the blocker instead of choosing by recency or clearing artifacts. When an `AMBIGUOUS` block names only past deliveries the user no longer cares about, name the ignorable delivery slug(s) and offer to exclude them from ambiguity resolution; only after explicit user confirmation, add each slug with `.product-loop/bin/boatstack-helper ignore-delivery --repo . --feature <slug>` (a bounded, provenance-safe write to `workflow.ignored_deliveries` — never hand-edit config or delivery state). Any new, unlisted ambiguous delivery still pauses the workflow.
