You cannot walk away, and you also cannot trust auto-merge
Queue the work with /automate. Default: it parks a reviewed PR and tells you if a human is required. Desktop banners are on; --notify adds webhooks. Pass --auto-merge and it squash-merges only when the seven-condition fail-closed trusted gate holds. The sixth condition re-classifies the PR head with classify-risk.sh; a high-risk or unclassifiable diff always parks, with no override. The seventh is the rules gate: rules-gate-verdict.sh parks a failing, unresolved, unstamped, or unreadable stamped gate-countable must-rule check, with no override. --trust-unprotected is the explicit escape hatch for an unprotected branch. Anything unreadable parks. It does not silently ship.
