`[2026-07-13]` **A same-image redeploy does NOT reload a bind-mounted config — the ModelRegistry boot-caches it at `__init__`.** After the config was synced on-disk (infra-ops validated) and `docker compose up -d` re-ran, the reasoning-off change STILL didn't take: an unchanged image makes `up -d` a no-op (no container recreate), so the process kept serving the pre-sync config. Fix = a surgical `docker restart <container>` (same image, no pull) → the process re-boot-reads the config. **When an on-disk config change doesn't take effect, suspect the process cached it at startup; force a container RESTART, not a redeploy** (a docs-only forcing-commit also won't rebuild if docs are paths-ignored in CI). This is the config-plane sibling of the `[2026-07-06]` stale-image foot-gun.
