+# Add the ratatoskr memory-plane provider endpoint to the personal Worldtree's
+# Bifrost client allowlist, so a consumer may BIND it at session-create.
+#
+# Worldtree gates `bifrost.endpoint_url` against BIFROST_CLIENT_ALLOWED_HOSTS
+# (host:port CSV in /opt/worldtree-personal/.env). The affect plane :8390 was
+# listed during its deploy; the memory plane :8391 (ratatoskr-memory-provider
+# on nh3-dev) needs appending — otherwise POST /sessions 422s
+# (`endpoint_url must be HTTPS or match BIFROST_CLIENT_ALLOWED_HOSTS`) before
+# any handshake fires. See the eshpfi memory note `reference_bifrost_plane_wiring`.
+#
+# Idempotent + rerunnable: guards are sudo-free (live container env via the
+# docker group; backup via `test -e`); the append self-guards inside its
+# sudo bash -c; the recreate skips when the live env already carries the host.
+# Surgical: recreates ONLY worldtree-api (the validator); matrix is untouched
+# and picks up the value on its next natural redeploy. `--pull never` uses the
+# local pinned image so the recreate needs no gitea registry auth.
+#
+# CRITICAL pin-preservation: WORLDTREE_IMAGE is injected by the Worldtree CI/CD
+# at deploy time, NOT stored in .env, so a bare `compose up` falls back to the
+# compose default `:latest` — a STALE locally-cached build whose stricter config
+# validation crash-blocks startup on this instance's agent-profile drift (agents
+# reference removed LLM profile qwen3.6-35-a3b-heretic). The recreate step below
+# therefore re-derives the live pin from the untouched matrix sibling and passes
+# it explicitly. (Learned the hard way 2026-06-15 — a pinless recreate took the
+# personal API down for ~1 min until restored on the correct pin.)
