Phase Close Gate
Kind: algorithm
Record: algorithms:phase-close-gate
Canonical: Algorithms
Closure: Dependencies in load order
Make completion a gated state of the plan rather than a judgment call — a phase closes only when all tasks are done, a dry reconciliation pass holds, verify is clean for the chosen scope, and the coverage graph confirms the ripple set; otherwise the loop returns to execution.
