Drift-audit Group 5 (high-severity contract drift):
- MCP read-only keys could call every write tool: the Bearer resolver
discarded api_key.scope and dispatch had no gate. Add resolve_bearer()
(returns user_id + scope) and a scope gate in the /mcp ASGI wrapper that
buffers the JSON-RPC body and rejects tools/call for any tool outside a
read all-list when scope=='read' (default-deny for unknown/new tools).
- Shared project notes/tasks panel was empty for non-owners: get_project_notes_route
now queries notes/milestones with the project OWNER's uid (mirrors the
already-fixed milestones route).
- Shared editors couldn't save/delete shared NOTES (tasks worked): the three
notes write routes now resolve via get_note_for_user, gate on can_write_note,
and write as the owner — matching the tasks routes.
- Event timezone drift: naive datetimes from the MCP date+time split are now
localized to the user's tz at a single canonical service point (create_event
/update_event), so MCP- and UI-created events agree. tz-aware inputs
(REST/CalDAV) pass through untouched.
- create_note validates status/priority (TaskStatus/TaskPriority), closing the
MCP create_task path that let out-of-enum values persist (no DB CHECK).
Tests cover resolve_bearer scope + the write-tool classifier.
