Narrow Scribe to a Claude-Code work system-of-record (milestone #194, decision note #1759). Wholesale removal per rule #22 — backend + schema half. Calendar/events + CalDAV: delete models/event, services/{events,caldav, caldav_sync}, routes/events, mcp/tools/events; strip event branches from backup (bump v3->v4), dashboard (upcoming_events), trash, recent, and the mcp server read-only allowlist + instructions. Typed entities (person/place/list): delete mcp/tools/entities; drop the notes.metadata (entity_meta) column from model/service/routes and the knowledge browse service. note_type STAYS — it also marks 'process' notes. Scheduler: event_scheduler -> recurrence_scheduler, keeping only the recurring-task spawn job (drops event reminders + CalDAV sync). Schema: migration 0069 drops the events table + notes.metadata column + orphan caldav settings rows (faithful downgrade recreates them). KEEP: recurrence.py (task recurrence), notifications task reminders, graph view, and every work surface. Frontend + plugin/docs true-up follow next.

"""drop events table + notes.metadata column (retire calendar + entity surfaces)

Revision ID: 0069

Revises: 0068

|
Create Date: 2026-07-19
|
|
|
|
The personal-assistant surfaces (calendar/events + CalDAV, and the typed
|
|
person/place/list entities that stored structured fields in notes.metadata)
|
|
were removed when Scribe narrowed to a Claude-Code work system-of-record.
|
|
This migration drops their storage:
|
|
|
|
- the `events` table (all calendar/CalDAV data)
|
|
- the `notes.metadata` (entity_meta) JSONB column — it only ever held
|
|
person/place/list structured fields. The `note_type` column STAYS: it
|
|
also distinguishes 'process' notes.
|
|
- orphan CalDAV settings rows (nothing reads them after the removal)
|
|
|
|
Downgrade recreates the table + column structure at its pre-removal shape.
|
|
The dropped data itself is not recoverable.
