## Work Done

### v8: Delete + Granular Restore
- [x] `DELETE /api/backups/{project}/{env}/{name}` endpoint with path traversal validation
- [x] Restore `mode` query param (full/db/wp) → passes `--db-only`/`--wp-only` to ops CLI
- [x] Delete button on every backup row in Level 2 drill-down
- [x] Restore Mode radio buttons (Full / Database only / WP-Content only) in restore modal

### v9: Multi-Select, Upload, Source Selector, URL Routing
- [x] URL hash routing — `#/backups/mdf/dev`, `#/dashboard/table`, `#/system` — browser refresh preserves location
- [x] Multi-select delete — checkboxes per row, select-all header, blue selection bar, bulk delete
- [x] Upload to offsite — purple "Upload" button on local-only backups
- [x] Restore source selector — Local/Offsite radio buttons when backup exists in both locations

## Key Decisions / Learnings

- Path traversal validation is required on delete endpoint (user-supplied filename in URL)
- Static files are volume-mounted (not COPY'd) — frontend changes don't require container rebuild
- URL hash routing lets users bookmark specific dashboard views and survive page refresh
- Granular restore (db-only / wp-only) avoids full restore when only one component needs recovery

## Pending

- Selection bar spacing CSS gap not taking effect (possible browser cache issue)
