Safety prerequisites for the P0 rollout, landed BEFORE any sync.sh change so a bad
harness change cannot strand a node. .claude/harness/VERSION (1.0.0) lets a session
detect partial rollout; .claude/scripts/force-pull-raw.sh is a hook-free git rescue
(dry-run by default; --confirm hard-resets to origin/main, saving prior HEAD to a
recovery branch).
