Why: prepare a reviewable delivery window and migration contract that reduces repeated synchronization while preserving final CI and approval requirements.
Evidence: SELF precheck, document checks and read-only platform observations are preserved in .task/feature-merge-queue-policy-draft.md; runtime queue and platform trials remain NOT_RUN.
Impact: proposed policy, project entry and task record only; scripts, workflow, platform protection and guideline gitlink are not changed by this draft.
