  "description": "The v6 generation of the plan identity manifest. New schema-URL generation per RFC 9.1: the v1/v2/v5 manifest shapes are frozen and a v6 plan never rewrites one. Written exactly once, as the first file of the guarded materialization sequence (shared/ledger.py materialize: manifest -> contract -> approval), it carries the A12 contract pointer that makes a plan's v6-ness discoverable even when materialization was interrupted between the manifest and the contract — the ledger then refuses execution until the contract lands and re-running materialize with the same inputs completes it. The pointer is never edited: a changed contract is a revision under contracts/, recorded through the refine amendment path.",
