User asked for one meter per badblocks pattern. The drawer now shows
4 meters (one per pattern: 0xaa / 0x55 / 0xff / 0x00), each split
into write (left, blue) + verify (right, green) halves so a glance
shows both which pattern is current AND whether you're writing or
verifying within it.
Backend:
- New columns burnin_stages.bb_phase (1-8) + bb_phase_pct (0-100)
via idempotent ALTER TABLE migration
- _update_stage_bb_phase() helper called from the badblocks parser
on every tick (when phase or percent changes)
- /api/v1/drives/{id}/drawer SELECT now returns the new fields
Frontend (app.js + app.css):
- _drawerRenderBadblocksMeters(phase, phasePct) computes per-pattern
fill state and emits 4-meter HTML with W/V sub-labels
- Conditional render: only shows when stage_name === 'surface_validate'
AND bb_phase is set, so historical pre-1.0.0-44 stage rows render
unchanged (single percent, no meters)
3 new tests cover the migration columns, single-tick persistence,
and overwrite-on-second-tick. Total suite: 75 tests.
Image rebuilt and tagged but NOT deployed — 4 burn-ins are running
right now and a recreate would SIGHUP them. Deploy with
`docker compose up -d` after the current batch finishes; the
migration runs at init and the meters light up for the next batch.
