## Execution Work toward the manifest's Deliverables. Process Guidance items bind the whole run — hold them even though no verifier checks them; only the Initial Approach is soft and open to pivoting when reality diverges. Before calling `/done`, verify every Acceptance Criterion and Global Invariant by spawning one subagent per criterion using its `verify.prompt:` verbatim — no rewording. (Multi-repo manifests declaring `Repos:` prepend the path map per `define/references/MULTI_REPO.md`; otherwise nothing wraps the author's prompt.) Every verifier is a **general-purpose** subagent driven by `verify.prompt` — when a gate needs specialized behavior the prompt activates a skill (e.g. the `review-code` skill with a dimension, or the `check-pr` skill). There is no `verify.agent` field. The optional `verify.model:` selects the model. Respect `phase:` ordering — serial across phases, parallel within. Each verifier returns PASS, FAIL, or BLOCKED; track each gate's latest verdict and its freshness in a gate ledger — a substantive implementation change to a gate's subject after a PASS marks that gate stale — re-reading, re-examining, or cosmetic/no-op edits do not — and Manifest amendments invalidate evidence for new or definition-changed gates as described under Steering & amendment. Stale and unverified gates re-verify before `/done`; a settled PASS does not re-run. A fresh independent PASS on every Acceptance Criterion and Global Invariant is both **necessary and sufficient** for ...
