serversdown c14a8c54db event_browser: Instantel-printout-style polish
Apply the cheap visual wins from the BW Event Report layout:

  1. Channel order reversed → MicL (top), Long, Vert, Tran (bottom)
     to match the Instantel printout.
  2. Shared bottom time axis — x-axis ticks only render on the
     bottom-most data channel; other channels hide ticks so all four
     visually share one time scale.
  3. Triangle trigger markers above and below the t=0 dashed line.
  4. Horizontal zero-baseline (dotted) per channel with "0.0" label
     on the right edge — Instantel convention.
  5. "Print view" toggle that flips dark→light theme (white panels,
     light grids, dark text) so the viewer can render usefully on
     paper-style output / @media print.
  6. Per-channel PPV stats table in the metadata header, with Peak
     Vector Sum displayed prominently.
  7. Colors adjusted to approximate BW trace colors (magenta MicL,
     blue Long, green Vert, red Tran).

Future PDF-export work will reproduce the same layout server-side
once you upload a real example PDF and we pick a rendering pipeline
(weasyprint / chromium --print-to-pdf / etc.).

serversdown 460006e5cd sfm: stored-event browser at /events
New standalone HTML page (sfm/event_browser.html, ~470 lines, Chart.js)
that lets you browse persisted events from the SeismoDb + WaveformStore.
Companion to the existing live-device viewer at /waveform:

  /waveform  — connect to a unit and pull events in real time
  /events    — browse events already stored in the DB

Flow:
  1. Page loads → GET /db/units → populate serial dropdown
  2. Select serial → GET /db/events?serial=X&limit=500 → event list
  3. Click event → GET /db/events/{id}/waveform.json → render

Layout is Instantel-printout-ready: channels stacked vertically in
Tran / Vert / Long / MicL order, trigger line at t=0, peak labels,
clean dark theme.  Frames the future PDF-export feature without
needing extra layout work.

Smoke-tested against the dev prod-snapshot — 4 channels render with
correct peaks for K558 events (L=0.3 in/s = the offset-fault peak
we've been chasing all week).

CHANGELOG entry added under [Unreleased] per the v0.20.0 release plan.

## [Unreleased]
### Added
- **Stored-event browser** — new standalone HTML page at `GET /events` (`sfm/event_browser.html`). Pick a serial from the unit dropdown, scroll through that unit's events (newest-first), click any event to render its decoded waveform via the existing `/db/events/{id}/waveform.json` endpoint. Dark-themed Chart.js viewer, channels stacked vertically (Tran / Vert / Long / MicL — Instantel printout order, designed PDF-export-ready), trigger line at t=0, peak labels, search/filter, false-trigger flag honored. Companion to the existing live-device viewer at `/waveform`; the two routes are now clearly delineated in their docstrings.
- **Histogram body codec — uint8 peak count fix.** Per-channel peak fields at `block[6]/[10]/[14]/[18]` are `uint8`, not `uint16 LE` spanning `block[6:8]` etc. The original interpretation was byte-exact on the N844 fixture corpus only because every annotation byte (`block[7]/[11]/[15]/[19]`) in those fixtures was zero. On non-N844 events with non-zero annotation bytes (observed across BE9558 Tran-drift and BE18003 Histogram+Continuous units), the old interpretation produced peaks up to 268 in/s per channel and 35× inflated PVS sums when first deployed to prod (rolled back same day; properly fixed in this release). Cross-correlated against BW's per-interval ASCII export on K558 / T003 / N599 / N844 corpora — 100% byte-exact on T/V/L, 99%+ on M (sub-precision rounding). Annotation byte preserved on each record as `record["annotations"]` for future RE. Verified against ~3,500 blocks across 5 in-repo fixtures + a synthetic K558 interval-12 regression block.
- **`apply_bw_report_dict_to_event` helper** in `minimateplus.event_file_io`. Mirror of `apply_report_to_event` for the projected sidecar dict shape — used by the backfill path, which has the preserved `bw_report` block but not the original `.TXT` file. BW's reported peaks (and `sample_rate` / `record_time`) now win over codec output during `--force` backfill, matching ingest-path behavior.
- **`scripts/check_bw_report_preservation.py`** — two-step snapshot/diff tool to verify that `backfill_sidecars.py` doesn't wipe the `bw_report` block from existing sidecars. Classifies every sidecar as PRESERVED / CHANGED / WIPED / STILL_MISSING / NEW / ADDED / REMOVED. Exit code 1 if any WIPED or CHANGED entries are found, so it can gate a CI step or deploy script.
### Fixed
- **`scripts/backfill_sidecars.py` no longer wipes `bw_report`.** Before this fix, `event_to_sidecar_dict` silently dropped the preserved `bw_report` block during every backfill, since the function only emits a `bw_report` when called with a live `BwAsciiReport` dataclass (which the backfill doesn't have — only the projected sidecar dict). Now we read the existing sidecar's `bw_report` and overlay it onto the regenerated sidecar, alongside the existing `review` and `extensions` preservation.
- **`scripts/backfill_sidecars.py --force` no longer overwrites BW-overlaid DB peaks with codec output.** The backfill path now calls `apply_bw_report_dict_to_event` before the DB upsert, mirroring what the ingest path does (`/db/import/blastware_file` parses the `.TXT` into a `BwAsciiReport`, calls `apply_report_to_event`, then upserts). Without this, events where the codec doesn't fully decode (waveform walker edge cases on SP0/SS0/SV0-style events, histogram `byte[5]!=0` sub-format) ended up with PVS=0 in the DB after a `--force` backfill; bit on prod 2026-05-22, rolled back the same day.
- **Thor IDF files no longer attempted as BW events in backfill.** `scripts/backfill_sidecars.py` now filters out `.IDFW` / `.IDFH` files in `_looks_like_event_file()`; they share the `.X0W` / `.X0H` suffix shape but use a separate ingest path (`WaveformStore.save_imported_idf`) and aren't decodable by `event_file_io.read_blastware_file`.
### Docs
- **CLAUDE.md** — added a three-tier conceptual architecture model (SFM / SDM / shared codec library) near the top of the file, with a placement rule for where new code goes. Documents that what is conceptually SDM (database, waveform store, ingest, `/db/*` endpoints) still lives under `sfm/` for historical reasons; rename deferred until the codebase is quiet enough for a clean refactor.
- **README.md** — added a "Strategic direction" lead-in to the Roadmap that frames seismo-relay as a suite of cooperating components (not a single app), and an explicit "Terra-View ↔ SFM device control" roadmap section with a concrete implementation checklist (auth as hard prerequisite, embedded live-monitor view, action history, Series IV live-device support).
- **`docs/histogram_codec_re_status.md`** updated with the uint8 retraction and the annotation-byte status.
- Three known issues recorded in the Roadmap that were discovered during prod validation: (1) `bw_ascii_report` parser misses PPV / `vector_sum` on some `.TXT` formats (5 events on prod); (2) NULL-timestamp duplicate-row dedup needed (2 events on prod); (3) histogram body sub-format with `byte[5] != 0` not yet decoded (~3 events on prod with empty `.h5` plots).

## v0.19.0 — 2026-05-20
The "device-family separation" release. Tightens the boundary between Series III (MiniMate Plus / Blastware) and Series IV (Micromate / Thor) so the UI and storage layer dispatch deterministically by family instead of sniffing filename extensions or magnitude heuristics.
