+- **2026-05-25 config-as-bind-mount (Worldtree #205, v0.25.2):**
+  `/app/config/` is now a bind-mounted host dir
+  (`${WORLDTREE_CONFIG_DIR:-./config}:/app/config` in compose).
+  Per-instance edits persist across image upgrades — no more
+  in-container hacks for things like rate-limit defaults or
+  per-agent profile overrides. Entrypoint shim runs as root,
+  chowns + seeds the bind dir from `/app/config-defaults/` on
+  first boot when empty, then drops privileges via `gosu` to the
+  worldtree user. Idempotent against pre-existing populated dirs.
+  Default `per_user_tokens_per_hour` raised image-side from 1M to
+  1B at the same time. Shipped after a v0.25.1 attempt that wedged
+  on a uid-mismatch in the cp+chown sequence (host bind dir was
+  root-owned, container user uid 1000 couldn't write); v0.25.2
+  fixed via root-then-drop pattern. Full thread:
