Restore graphless host-edge runtime and reject stale same-PID leases

Problem

The local Docker hard cut starts the container-plane Orchestrator but never instantiates the already-ratified host-edge role. The signed Shape-B receiver owns final-mile wake delivery only; it cannot supervise host model processes. LM Studio therefore has no durable owner after a restart, so MC/KB can remain reachable while semantic capability is absent.

A separate restart defect survives PID reuse: a new PID-1 Orchestrator can mistake a lease written by the previous PID-1 process epoch for its own live lease and defer heavy maintenance until TTL expiry.

Evidence correction

The original WAL-root mismatch claim is withdrawn. On merged #16218, the local plane uses Docker-owned volumes. The MC writer and in-process drainer both read AiConfig.memoryWal.dir, explicitly relocated to the persistent /app/.neo-ai-data/sqlite/memory-wal. The observed alternate-root backlog belonged to the retired pre-Docker import source, not the live target.

Chroma rebuild/version work and broader health-truth claims are separate lanes.

Fix

• Run the existing scheduler engine a second time as graphless authorityProfile=host-edge, with a distinct host-only state root.
• Enable only LM Studio supervision for P0; pin the local endpoint and selected generation/embedding models. Docker retains every graph/corpus lane.
• Keep the signed wake receiver as a separate final-mile boundary; do not reinstate Shape C.
• Treat a same-PID lease acquired before the current process start as stale, without changing the persisted lease schema.
• Replace the obsolete checkout-folder cutover instructions with a Docker-volume steady-state runbook. Checkout .neo-ai-data is an import source, never a live target.

Acceptance

• host-edge boots without asserting or opening a graph/Chroma plane.
• Its enabled authority is LM Studio only, at 127.0.0.1:1234, with the selected chat and embedding models.
• Host-edge, wake receiver, and Docker state roots are distinct.
• Same-PID previous-epoch leases are reclaimed; current-epoch and other live-PID leases remain active.
• Static/unit tests cover the authority, provider, placement, and lease boundaries.
• [L4-deferred — operator handoff needed] After the active re-embedding completes, an operator receipt proves the host-edge authority file, loaded models, and one real signed wake.

Authority

• ADR 0014: exhaustive host-edge / container-plane ownership map and the #16210 amendment.
• ADR 0019 §10.7: Docker-owned local plane placement.
• #16218: merged canonical local Compose target.
