The 2026-09-12 homepage outage slipped through because the live-fleet
Playwright suite was a manual 'MUST invoke' that deploys skipped. Wire it
into deploy.sh as the [3/3] gate: after a behavior-affecting deploy,
run tests/e2e/run.sh against the live fleet; a failure exits DEPLOY
INCOMPLETE. Add --skip-e2e as an emergency escape hatch. Update the
AGENTS.md deployment-completeness contract and flow diagram to match.
Verified: bash -n clean, --skip-e2e parsed, unknown flags rejected,
seam suite green (only the pre-existing comfyui test 73 fails).
