title: Update chattolib to Chatto 0.4.3 status: completed type: task priority: high created_at: 2026-07-09T15:50:04Z

updated_at: 2026-07-09T15:51:27Z

Chatto server on chat.chatto.run is now at 0.4.3. Regenerate the proto bindings from upstream, diff the API surface for breaking or additive changes, adapt the client if needed, bump chattolib to 0.4.3, run the full check + live-verify, then publish and push.

Summary of Changes

• Reran scripts/generate_pb.sh against upstream main. Regenerated Python bindings picked up the two upstream proto changes:
  • chatto.api.v1.ListRoomMembersRequest: default page size doc-comment changed from 20 to 250 (no wire/API change).
  • buf/validate/validate.proto: comment/example updates only.
• No client code changes required; every method, dataclass, and enum still matches the current server.
• Bumped pyproject.toml version from 0.4.2.post2 to 0.4.3 per the [[feedback-versioning-tracks-chatto]] policy (chattolib version tracks Chatto server X.Y.Z).
• Full check: ruff, mypy --strict, pytest (48 passed, 4 skipped) all clean.
• Live-verified against Chatto HQ (now serving v0.4.3) with the RoboChatto account: login, viewer, list_rooms, get_motd, list_roles all decode correctly.
