What is still missing for these phases:
- keeping the cutover inventory current as more surfaces move
- broader lifecycle ownership beyond the loader state machine, service-lifecycle boundary, session-owned activation state, and explicit discovery-policy, activation-policy, and finalization-policy outcomes, remaining policy gate ownership, and broad host-owned registries described for Phase 2

- compatibility plugin-registry policy now has a host-owned helper boundary in `src/extension-host/plugin-registry-compat.ts`

Why this matters for this spec:
- event work should land on top of a host-owned boundary and normalized contribution model rather than on top of more plugin-era runtime seams
- the current implementation has deliberately not started canonical bridge or stage work before those earlier boundaries were in place, including the first loader-runtime, record-state, discovery-policy, activation-policy, finalization-policy, low-risk registry-write, hook-compat, plugin-api, plugin-registry, plugin-registry-compat, plugin-registry-registrations, and service-lifecycle seams
