Operators running a packaged layout with no git checkout declare the mode explicitly with `GITEA_MCP_RUNTIME_MODE`. +3. ~~Promotion checklist script that emits the durable promotion marker fields.~~ **Landed** as `scripts/promote-stable-runtime` (read-only; emits and validates the record) plus [`../stable-runtime-promotion-runbook.md`](../stable-runtime-promotion-runbook.md). + +Post-transport-flap proof is enforced per namespace: a flap invalidates every +`gitea-*` namespace at once, and author proof never transfers to reviewer, +merger, or reconciler (`namespace_not_reproven_after_flap`). + +**Not optional (issue #615 acceptance criterion 2):** operator guide and runbooks **must** cross-link this ADR (see §6).

Issue #615 references this path. +4. LLM/operator runbooks treat kill/restart/relaunch-from-worktree as **LLM violations**; process restart is **operator-owned**. +5. Unhealthy runtime (including **stale master parity**) stops normal mutation work until operator restore/reload, promotion/rollback, or #557 bootstrap — then re-verify parity before mutating. +6.
