title: Update chattolib to Chatto 0.4.9 status: completed type: task priority: high created_at: 2026-07-12T23:46:37Z

updated_at: 2026-07-12T23:48:14Z

Chatto HQ is now serving 0.4.9. Regenerate proto bindings from upstream, diff the API surface for breaking or additive changes, adapt the client if needed, bump chattolib to 0.4.9, run the full check + live-verify, publish, and push.

Summary of Changes

Regenerated proto bindings from upstream. Delta from 0.4.3:

Additive fields

• Message.deleted_at (google.protobuf.Timestamp) — surface added to the Message dataclass and its .parse() classmethod.
• GetSystemInfoResponse.asset_cleanup (AdminAssetCleanupStatus) with a new AdminAssetCleanupHealth enum. Passes through the existing raw-dict admin_get_system_info() return; no code change needed.

Metadata-only

• Several RPCs now advertise idempotency_level: DeleteAvatar, DeleteCustomStatus, DismissNotification, Unsubscribe, GetServer. No wire change.

Server-side validation tightening

• CreateMessageRequest.attachment_asset_ids now capped at 10 items with per-item length constraints. Server-enforced; no client change.

Bumped pyproject.toml from 0.4.3 to 0.4.9. ruff + mypy --strict + pytest (48 passed, 4 skipped) all clean.

Live-verified against Chatto HQ (0.4.9): login, viewer, list_rooms, get_motd all decode correctly.
