- Migration 004: acknowledged_by/acknowledged_at columns on alerts,
alert_comments table (FK cascade on delete)
- POST /api/alerts/{id}/acknowledge — stamps authed user + timestamp,
returns updated alert with acknowledged_by username
- DELETE /api/alerts/{id}/acknowledge — clears ack (204)
- GET /api/alerts/{id}/comments — list in chronological order
- POST /api/alerts/{id}/comments — add comment (returns 201)
- DELETE /api/alerts/{id}/comments/{commentID} — own comments only (204)
- All alert queries now LEFT JOIN users for ack username
- Migration 003: alerts table with fingerprint UNIQUE, JSON label/annotation
columns, nullable ends_at, and indexed status/name/received_at
- POST /api/alertmanager/webhook — upserts each alert by fingerprint;
zero endsAt ("0001-01-01") stored as NULL (still firing)
- GET /api/alerts — filtered list (?status, ?name, ?from, ?to, ?limit)
- GET /api/alerts/{id} — single alert lookup
