AUTHORITY     : PHASE CHRONOLOGY / INDEX ONLY. This index MUST NOT authorize
                execution and MUST NOT independently define the current
                ingestion cursor. The cursor is defined by the canonical
                checkpoint and reported by CURRENT_PROJECT_STATE.md.
Close SHA = full authoritative commit id resolved from Git (not inferred).
