Why: A LOCAL_READY receipt must permit normal target advancement without accepting a rewind or divergent target history after its observation.
Evidence: Two disposable real Git regressions reproduced erroneous successful recovery before the guard; all 18 task recovery tests pass afterward. Raw SELF receipts are in the task card.
Impact: Reject abnormal target ancestry before receipt import; preserve normal local recovery and strict delivery defaults. Correct stale implementation-stage documentation without activating the queue.

Why: an existing authorized task should not merge a moving target merely to resume local work, while new task startup and delivery remain strict.
Evidence: SELF red-green recovery and environment regressions; task, recovery, evidence and local-mode write-guard suites passed through make evidence.
Impact: add explicit LOCAL_READY and task-resume, validate worktree/card/baseline and receipt purpose, preserve schema 1 and prevent local receipts from starting or releasing tasks.
