Three additions to the surface_validate drawer block:
1. **Phase caption** below the meters: "Pattern 2 of 4 · Verify 0x55
· 47% within phase". Pure JS — no schema change. Makes the
visual grammar explicit without needing the operator to mentally
map phase=4 to "verifying pattern 2".
2. **Bad-block badge** in the vitals row. Green at 0, red at >0.
The number was already on the stage row but burying it in the
log felt wrong — surfacing it next to temp/speed/ETA keeps it
in eye-line during long runs.
3. **Per-pattern duration history** below the caption. New
bb_phase_history JSON column (idempotent migration) maps
{phase_num: ts}. Parser stamps the timestamp on every phase
transition (and on stage entry for phase 1). Drawer diffs
consecutive write-phase starts to derive "0xaa: 14h 22m"
for completed patterns. Once one pattern is done you can
predict the rest without leaving the drawer.
Persistence is idempotent: re-entry of the same phase keeps the
original timestamp so a transient parser reset doesn't blow away
history. JSON parse failures fail gracefully (no row rendered).
The drawer's surface_validate area now leads with a row of operator
vitals computed from data already in the response:
- Temp: drive temperature with cool/warm/hot colour (≥48 red, ≥42 yellow)
- Speed: live MB/s, NULL until second progress sample arrives
- Elapsed: time since stage started_at
- ETA: extrapolated from overall progress; suppressed under 0.5%
to avoid the "47 days remaining" artefact early in pattern 1
Live MB/s comes from a new bb_mbps column on burnin_stages, computed
in the badblocks parser as (delta_overall_pct / 800) * size_bytes / dt.
Skipped on phase transitions (per-phase pct resets) and sub-second
samples (noisy).
Drawer endpoint now passes drive.temperature_c through; JS stashes
the latest drive object in _DRAWER_LAST_DRIVE so the burn-in renderer
can pull it for the vitals row without changing call signatures.
Tightened table CSS in this same session is unrelated and shipped
already in earlier rounds via the bind-mounted app.css.
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.
Three low-severity findings from Codex on the 1.0.0-37 split:
1. Trim dead package-level imports in routes/__init__.py — only
`poller` was actually used; auth/burnin/mailer/settings_store
were the exact shadowing footgun the absolute sub-router
imports work around. Reword the comment block to match.
2. Thread `operator` through smart_start + smart_cancel.
Previously the JS client sent it but the server ignored it;
add audit_events rows (smart_test_start / smart_test_cancel)
so the field is actually meaningful.
3. New tests/test_routes_resolution.py — guards two historical
regressions: /api/v1/burnin/export.csv must register before
/{job_id} (FastAPI int-coerce 422 trap) and the mailer
back-compat shim `from app.routes import _fetch_drives_for_template`
must keep importing. Plus a sub-router enumeration test that
catches missed include_router calls in future splits.
Largest routes/ slice yet — drives.py (8 endpoints) and burnin.py
(4 endpoints). Drives helpers live in _drives_helpers.py so the
dashboard SSE handler in routes/__init__.py and mailer.py can both
keep using them via re-export.
routes/__init__.py shrinks from 815 → 163 LoC; only the dashboard /
and /sse/drives stream remain there. Routes split is now functionally
complete: 12 files, ~1800 LoC distributed by feature.
