+- Phase 8 - OpenClaw Integration. As of 2026-04-12 the T420 OpenClaw
+  helper (`t420-openclaw/atocore.py`) is verified end-to-end against
+  live Dalidou: health check, auto-context with project detection,
+  Trusted Project State surfacing, project-memory band, fail-open on
+  unreachable host. Tested from both the development machine and the
+  T420 via SSH. The helper covers 15 of the 33 API endpoints — the
+  excluded endpoints (memory management, interactions, backup) are
+  correctly scoped to the operator client (`scripts/atocore_client.py`)
+  per the read-only additive integration model.
