## v0.17.0 — 2026-05-17
The "field rescue + DB management" release. Hardened against units that are stuck in a runaway call-home loop, and added an operator-facing path for purging bogus events that those same units dump into the DB before recovery. All work in this release was driven by the BE9558H incident (full incident log + recovery procedure at `docs/runbooks/wedged_unit_recovery.md`).
### Added — wedged-unit recovery toolkit
A toolkit for breaking the call-home loop on a misbehaving unit whose firmware is too busy to keep up with normal request/response handshakes. Tested in production against BE9558H (16 May 2026) — a unit with a stuck-triggered Long-axis geophone that had been call-homing the office BW ACH server every 30 seconds for hours. Endpoints layered from "single attempt" to "siege mode" to suit different contention levels:
- **`GET /device/events/storage_range`** — SUB 0x06 probe. POLL + one read; ~2s. Returns first/last event keys and an `is_empty` flag. Use to triage whether a unit has stored events without invoking the slow `count_events()` 1E/1F chain (which choked on BE9558H's corrupted event chain).
- **`GET /device/events/index`** — SUB 0x08 probe. POLL + one read; ~2s. Returns the lifetime event counter (does NOT decrement on erase — use `storage_range` for "right now" state).
- **`POST /device/events/erase`** — full erase sequence `0xA3 → 0x1C → 0x06 → 0xA2` (confirmed 2026-04-11, see the protocol reference). Resets event keys to `0x01110000`. Caller's responsibility to disable ACH first if the underlying trigger condition will re-fill the buffer.
- **`POST /device/rescue`** — one TCP session, short connect+recv timeouts: POLL → disable ACH (compliance config write) → erase events → close. Designed for race-loop usage when the device is busy in another session. 503 on connect-refused, 502 on protocol failure, 200 on full sequence success.
- **`POST /device/stop_monitoring_blind`** — fire-and-forget Stop Monitoring (SUB 0x97), TCP-only. Dumps `SESSION_RESET + POLL_PROBE + SESSION_RESET + POLL_DATA + 0x97 × repeat` and closes without reading any S3 response. The full POLL preamble is required — write commands without it are silently ignored by the device's protocol parser (false-positive surface area that bit the first version of this endpoint). Use when the device's firmware can't keep up with full request/response but might process inbound bytes at its own pace.
- **`POST /device/stop_monitoring_spam`** — server-side hammer loop, duration-bounded. Open TCP → write the same blind payload → close → repeat as fast as possible until `duration_s` elapses. Configurable `connect_timeout` (default 500ms) and `repeat` (frames per session). Reports `sent_ok`, `connect_failed`, `write_failed`, `rate_attempts_per_s`. Clamped to 5min duration.
- **`POST /device/stop_monitoring_slow_drip`** — opposite of spam. Open ONE TCP session, drip the wake handshake + stop frames at `interval_s` (default 3s) for `duration_s` (default 120s, max 10min). Each drip is ~23 bytes — well under any UART FIFO size. Opportunistically drains any inbound bytes the device sends back; `bytes_received > 0` in the response strongly suggests the device has started talking and the session is healthy. **This is the endpoint that saved BE9558H.** Spam mode had been overrunning the device's UART FIFO; slow drip stayed under it.
- **Six rescue scripts** under `scripts/` — thin bash wrappers around the endpoints, default `SFM_BASE_URL=http://localhost:8200` (direct, not via Terra-View proxy whose 60s timeout would cut off the longer endpoints):
- `rescue_device.sh` — race-loop wrapper for `/device/rescue`
- `blind_stop.sh` — race-loop wrapper for `/device/stop_monitoring_blind`
- `spam_stop.sh` — single-call burst hammer
- `slow_drip.sh` — single-call held-session drip
- `watch_unit.sh` — passive periodic reachability check (every N min, logs to file), useful for unattended overnight monitoring of a wedged unit
- **`docs/runbooks/wedged_unit_recovery.md`** — symptoms, quick-reference recovery procedure, the modem-layer mechanism (Sierra Wireless serial-port mode-flipping is the real failure mode — not the device firmware), and a table of "why simpler approaches don't work" so the next incident skips the dead ends.
### Added — operator event DB management
Endpoints powering Terra-View's new `/admin/events` page (v0.12.0). Designed for purging bogus events from a unit that's been forwarding them in bulk (e.g. a stuck-triggered seismograph dumping hundreds of junk events before it's recovered).
- **`DELETE /db/events/{event_id}`** — hard-delete one event row. Also unlinks the associated blastware binary (`.AB0*`), `.a5.pkl`, `.sfm.json` sidecar, and `.h5` clean-waveform files via the WaveformStore. Returns the per-file removal status. 404 if the event doesn't exist.
- **`POST /db/events/delete_bulk`** — filter-based or id-list-based bulk delete with safety rails:
- Filters (`serial`, `from_dt`, `to_dt`, `false_trigger`) combine with AND; same semantics as `GET /db/events`. `ids` is an additional inclusion list. Refuses to run with no filters (would wipe the whole table — raises 422).
- `confirm` must be `true` to actually delete. Otherwise returns a dry-run summary (`status: "dry_run"`, `matched: N`, `sample_serials: [...]`).
- `max_rows` (default 10,000) caps how many rows can be deleted by-filter in one call. If exceeded, returns `status: "too_many"` with a hint to narrow or raise the cap. Bypassed when only `ids` is supplied.
- **`_cleanup_event_files(row)`** helper in `sfm/server.py` — best-effort `unlink()` of all four sidecar paths derived from the row's `blastware_filename`. Logged at WARN if a path exists but unlink fails; the DB row deletion still proceeds.
- **`SeismoDb.delete_event(id)` and `SeismoDb.delete_events_bulk(...)`** in `sfm/database.py` — both return the deleted row dict(s) so callers can do file cleanup. `delete_events_bulk` raises `ValueError` if no filters are supplied.
### Changed
- **Default protocol recv timeout dropped from 30s → 10s** in `_build_client()`. The unit usually responds in well under a second over cellular; 10s leaves comfortable headroom for retransmits while failing reasonably fast when a unit is wedged. The two endpoints that perform full 5A waveform downloads still pass `timeout=120.0` explicitly so multi-minute event transfers are unaffected.
- **`_build_client()` now accepts an optional `connect_timeout`** (TCP-only) so rescue / race-loop endpoints can fail fast on busy modems without affecting the protocol-level recv timeout.
### Fixed
- **`GET /device/monitor/status` returned HTTP 500 + uncaught traceback when the device was unresponsive**. The retry-on-`Exception` inner block let the second `client.poll()`'s `ProtocolError` propagate out of the handler. Now wrapped in proper try/except — returns 502 with `{"detail": "Protocol error: No S3 frame received within 10.0s ..."}` on timeout, 502 on connection errors, 500 only for genuinely unexpected exceptions.
### Migration
No schema changes. No data migration required.
If you've been running a previous version against a wedged unit and accumulated bogus events, the new `/admin/events` page in Terra-View v0.12.0 (or direct `POST /db/events/delete_bulk` with `confirm: true`) is the cleanup tool. Watcher state on the upstream DL2 PC does NOT need separate cleaning — the watcher's `sfm_forwarded.json` keys on file sha256 and won't re-forward the same files.
### Pairing
This release pairs with **Terra-View v0.12.0**, which adds the `/admin/events` UI that consumes the new bulk-delete endpoints, the bulk false-trigger flagging on `/unit/{id}`, and the field-deployment workflow that uses the same `series3-watcher` → SFM ingest path as before.
---
## v0.16.1 — 2026-05-14
### Fixed
- **`record_type` always "Waveform" for forwarded events.** `read_blastware_file()` hardcoded `ev.record_type = "Waveform"` regardless of the file's actual type. The watcher-forward pipeline (the main BW ACH ingest path) compounds this by parsing files from a tmp path with a `.bw` suffix, so even a filename-based fallback inside the parser still wouldn't see the original extension. Now:
1. New `derive_record_type_from_filename(filename)` helper in `minimateplus/event_file_io.py` derives the type from the LAST character of the filename's extension (V10.72+ AB0T scheme: `H`=Histogram, `W`=Waveform, `M`=Manual, `E`=Event, `C`=Combo). Falls back to `"Waveform"` for old S338 firmware (3-char extensions ending in `0`) and any unrecognized suffix.
2. `read_blastware_file()` now calls the helper with its `path.name` so direct callers (the `--dry-run` path in `scripts/import_bw.py`, tests, ad-hoc scripts) get the right value automatically.
3. `WaveformStore.save_imported_bw()` overrides `ev.record_type` with the **original** filename's derived type after parsing (the tmp file inside the parser doesn't carry the original extension). This is the path the live watcher-forwarder hits, so the DB column now reflects the actual event type going forward.
Events ingested before this fix are stuck with `record_type="Waveform"` in the DB; a one-off backfill (`UPDATE events SET record_type = ... WHERE blastware_filename LIKE '%H'`) would fix them retroactively if desired. Terra-view's event modal also derives client-side from the filename, so the UI already shows the correct type for old events even without the backfill.
---
- Created a comprehensive runbook (`wedged_unit_recovery.md`) detailing the recovery process for units stuck in a call-home loop, including symptoms, recovery steps, and explanations of the failure mode.
- Added `blind_stop.sh` script to send stop-monitoring commands in a tight loop for unresponsive devices.
- Introduced `rescue_device.sh` script to disable Auto Call Home and erase events from a busy device.
- Implemented `slow_drip.sh` script to send stop-monitoring frames at a slow rate to prevent UART overrun.
- Developed `spam_stop.sh` script to rapidly send stop-monitoring commands to a device.
- Created `watch_unit.sh` script for passive monitoring of device reachability, logging results over time.
Pre-v0.16.1 (commit aac1c8e), every event ingested through
read_blastware_file got record_type="Waveform" regardless of actual
type because the field was hardcoded. New ingests derive correctly
from the AB0T filename scheme (H/W/M/E/C). Existing rows still hold
the wrong value.
This script walks the events table, derives the correct record_type
from each row's blastware_filename, and bulk-updates rows that differ.
Idempotent + dry-run by default.
Usage:
python -m scripts.backfill_record_type --db bridges/captures/seismo_relay.db
python -m scripts.backfill_record_type --db bridges/captures/seismo_relay.db --apply
Terra-view's event-detail modal already derives the record_type
client-side from the filename for display, so operators see the
correct type in the UI even before this backfill runs. This script
brings the DB column in line with what the UI is already showing —
matters for reporting and any downstream consumer that reads the
column directly.
The BW ACH ingest path was inserting every event with
record_type="Waveform" regardless of the actual type because
read_blastware_file() had `ev.record_type = "Waveform"` hardcoded, and
the live watcher-forward path parses files from a tmp path (suffix
".bw") that doesn't carry the original extension.
V10.72+ MiniMate Plus firmware encodes the event type as the last
character of the AB0T extension scheme (H=Histogram, W=Waveform,
M=Manual, E=Event, C=Combo). This change:
1. Adds derive_record_type_from_filename() public helper in
minimateplus/event_file_io.py
2. Uses it inside read_blastware_file() so direct callers (the
--dry-run path of scripts/import_bw.py, tests, ad-hoc scripts)
get correct types automatically
3. Overrides ev.record_type in WaveformStore.save_imported_bw()
using the ORIGINAL filename (source_path.name) — required
because the parser sees only the tmp file
Old S338 firmware (3-char extensions ending in `0`) and any
unrecognized suffix fall back to "Waveform".
Existing DB rows ingested before this fix are stuck with
record_type="Waveform" — a one-off SQL backfill would fix them
retroactively if desired. Terra-view's event modal also derives
client-side from the filename, so the UI already shows the correct
type for old events even without the backfill.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
The "BW ACH ingestion" release. Paired with series3-watcher v1.5.0,
every Blastware ACH event (binary + _ASCII.TXT report) lands in
SeismoDb with device-authoritative peaks, project metadata, sensor
self-check, and ZC/Time-of-Peak data — without depending on the
still-undecoded waveform body codec.
Bumps pyproject.toml + minimateplus/event_file_io.py TOOL_VERSION
to 0.16.0. README banner + CHANGELOG entry summarise the work
that landed across commits cdfe4ad..f83993a on this branch.
The series3-watcher v1.5.0 fix taught the WATCHER to look for BW
ACH's _ASCII.TXT report alongside each binary. But the SFM
SERVER's import endpoint only knew about the legacy <binary>.TXT
naming when building its TXT lookup table.
Effect: even though the watcher correctly shipped both files in
the multipart POST (and logged "+ <name>_ASCII.TXT attached"),
the server's reports dict was keyed on the wrong name, so
report_bytes resolved to None for every event. Without the
report, save_imported_bw fell back to broken-codec peak values
and no project info — exactly the same symptom as before the
watcher fix landed, just for a different reason.
Fix: when stripping the ".TXT" suffix, also recognise the
"_ASCII" trailer and reconstruct the binary's filename by
converting the last "_" back to ".". Register the report under
BOTH possible binary names so the subsequent lookup matches
whichever convention the operator's BW installation uses.
ACH convention (Blastware ACH):
binary T003L2G6.0E0H + report T003L2G6_0E0H_ASCII.TXT ✅
Manual export (operator clicks Save As Text in BW):
binary M529LK44.AB0 + report M529LK44.AB0.TXT ✅
Both for same event (e.g. ACH + operator manual save):
register under both names; binary lookup wins ✅
Smoke-tested against the four real fixture filenames in the
project archive. Full SFM suite still 62 pass.
For the user's situation: pull, restart, and the NEXT re-forward
pass (after deleting watcher state file again if needed) will
hit this code path, parse the report correctly, apply the
overlay onto the Event, and the upsert path will land
authoritative peak values + project info in the DB.
Two compounding bugs caused forwarded events to land in the DB with
broken-codec peak values (~10 in/s saturation on every channel) and
no project info, even when the watcher correctly paired a BW ASCII
report with the binary.
Bug 1: save_imported_bw built the sidecar JSON with the report's
authoritative peak / project values via event_to_sidecar_dict(
bw_report=...), but never overlaid those onto the in-memory Event
that flows to db.insert_events(). So the DB row got peak_values
from read_blastware_file()._peaks_from_samples() — which runs the
still-undecoded waveform body codec assuming raw int16 LE and
produces ±32K-shaped noise (= ±10 in/s at Normal range) regardless
of the actual signal. The sidecar JSON had the truth but the DB
columns (which the webapp queries for fast filter/sort) lied.
Bug 2: insert_events' IntegrityError handler only refreshed the
filename/filesize/a5_pickle/sidecar columns when a duplicate
(serial, timestamp) was seen. Peak values, project info,
sample_rate, record_type stayed locked in at whatever the FIRST
insert wrote. So even after Bug 1 was fixed, the historical
events in the DB (already inserted with broken-codec peaks) would
never get their values corrected, because a re-forward would just
hit IntegrityError and skip the field refresh.
Fix 1 (minimateplus/event_file_io.py + sfm/waveform_store.py):
- New apply_report_to_event(event, report) helper folds the BW
report's device-authoritative fields onto the Event in-place:
per-channel PPV, peak vector sum, mic PSPL→psi, project /
client / operator / sensor_location, sample_rate, record_time.
- save_imported_bw() calls the helper right after parsing the
report. The Event that flows to insert_events() now carries
correct values.
Fix 2 (sfm/database.py):
- insert_events()'s IntegrityError UPDATE now refreshes every
device-authoritative column from the new data: tran_ppv,
vert_ppv, long_ppv, peak_vector_sum, mic_ppv, project, client,
operator, sensor_location, sample_rate, record_type, plus
the existing filename/filesize/a5_pickle/sidecar fields.
- Preserves: id, waveform_key, session_id, created_at (immutable
/ FK fields), and false_trigger (operator review state).
End-to-end simulation verified:
- Step 1: import without report → DB has ±10 in/s peaks, no project
- Step 2: re-import WITH report → upsert path fires, DB now has
device-authoritative 0.005 in/s peaks + sensor_location
- Step 3: operator sets false_trigger=1, re-import again → flag
preserved, peaks remain correct
For the user's situation: deleting the watcher state file forces a
re-forward of all events. Each re-forward now pairs with its
_ASCII.TXT, applies the report onto the Event, and the upsert
refreshes the DB row. No DB nuke needed.
Full SFM suite: 62 passed, 44 skipped.
Previous query_units() only joined on ach_sessions, which is created
exclusively by the live ACH server. The BW-importer path
(/db/import/blastware_file → WaveformStore.save_imported_bw →
SeismoDb.insert_events) populates `events` but never creates an
ach_sessions row. Consequence: every serial whose events flowed in
through the series3-watcher forwarder was invisible to
/db/units (and therefore to the SFM webapp's fleet overview / units
list), even though the events were correctly populated in the
events table with proper serial attribution.
Rewrite query_units() to aggregate from BOTH tables and union the
serials:
- total_events / last_event_at come from `events` (every ingest path)
- last_session_at / total_monitor_entries / total_sessions
come from `ach_sessions` (ACH-only),
0 when no sessions exist for the serial
- last_seen = max(last_event_at, last_session_at)
Verified on the user's actual prod DB after the
repair_unknown_serials run: /db/units now returns 24 serials instead
of 2. All 3,257 watcher-forwarded events become visible in the
fleet overview without any further DB surgery.
The /db/import/blastware_file endpoint was bucketing every
forwarded event into serial='UNKNOWN' in the DB. WaveformStore
correctly decoded the serial from the BW filename and saved
files to <store>/<serial>/<filename> (e.g.
.../BE17353/S353L5KC.DR0H.h5), but the endpoint code called
db.insert_events(serial=_serial_from_event(ev)) — and
_serial_from_event was a stub that always returned None,
falling back to "UNKNOWN".
Effect on the user's prod server: 3,039 events forwarded across
24 distinct units, ALL inserted under serial='UNKNOWN'. The
on-disk waveform store + sidecars + HDF5s were fine, but the
SFM webapp's /db/units only showed the two original manually-
uploaded serials because every forwarded row had its serial
column zeroed to UNKNOWN.
Fix:
- WaveformStore.save_imported_bw() now surfaces the decoded
serial on the returned `rec` dict (rec["serial"]).
- The import endpoint uses rec["serial"] as the authoritative
fallback when the operator hasn't supplied a serial_hint query
parameter. Order of precedence:
query string `serial` → rec["serial"] → _serial_from_event(ev) → "UNKNOWN"
- Response payload now includes `serial` per file so the watcher
log lines (or any future caller) can see which unit each event
was attributed to.
Recovery for existing DB rows:
scripts/repair_unknown_serials.py walks the events table looking
for rows with serial='UNKNOWN' and re-attributes each one to the
serial decoded from blastware_filename. Updates the row in place
unless the target (serial, timestamp) already has a row, in which
case the UNKNOWN duplicate is deleted. Idempotent. Default
dry-run; pass --apply to commit.
Verified on the user's actual DB (dry-run):
UNKNOWN rows scanned: 3039
Updated to real serial: 2602
Deleted (duplicate of an
already-correct row): 437
Unresolved (bad filename): 0
After running the repair, /db/units will show all 24 units
correctly populated.
The four operator-supplied note fields in BW's Compliance Setup →
Notes tab (Project / Client / User Name / Seis Loc) have
USER-EDITABLE LABELS — an operator can rename them in BW's UI to
"Building:", "Site Address:", "Inspector:", or anything else, and
the ASCII export writes those literal labels verbatim. The
previous label-normalisation map approach (just added in commit
6a7e8c6) was fragile: it could only match label spellings we'd
enumerated in advance. An operator using "Site:" instead of
"Seis Loc:" would have their sensor location silently dropped.
What IS reliable: BW always writes the 4 user-notes lines
contiguously, in the same order, between the "Units :" line and
the "Geo Range :" line of the export. So parse them by POSITION:
position 1 → project
position 2 → client
position 3 → operator
position 4 → sensor_location
The original labels BW wrote are preserved in a new
`BwAsciiReport.user_note_labels` dict (canonical slot → literal
label string) so terra-view can render them as the operator named
them.
Removes the `_OPERATOR_LABEL_MAP` / `_normalise_label_for_lookup`
helpers and the elif-by-normalised-label branch in `parse_report`.
Replaces with a small state machine that flips on the "Units" line
and flips off on the "Geo Range" line.
Tests:
- Default-label fixtures (waveform + histogram) still populate
correctly, with operator's labels captured.
- Synthetic custom-labelled exports ("Building:" / "Site Address:" /
etc.) populate the right slots by position.
- Histogram-specific "Seis. Location:" works.
- Lines outside the Units→Geo Range range are ignored even if
they look like user notes (defensive against malformed exports).
- Partial blocks (fewer than 4 lines) leave later slots None.
- Extra lines beyond 4 are dropped (5th slot doesn't exist).
26 tests in test_bw_ascii_report.py (was 33; net drop reflects
parametrised label tests collapsed into 6 focused position tests).
Full SFM suite: 62 passed, 44 skipped.
Pairs with series3-watcher v1.5.0 which fixes the filename pairing
so the report reaches this parser in the first place.
Blastware writes the operator-supplied fields with different label
spellings across firmware versions and recording modes — most
notably "Seis. Location" on histogram exports vs "Seis Loc:" on
waveform exports. Previous parser only matched the latter, so
every histogram event silently lost its sensor_location field.
Replace the four hardcoded `key.rstrip(":") == "X"` branches with
a single `_OPERATOR_LABEL_MAP` dispatch table keyed by normalised
label (lowercase, trailing colon/period stripped, internal
whitespace collapsed). Adds these variants on day 1:
project: "Project:" / "Project"
client: "Client:" / "Client"
operator: "User Name:" / "User Name"
sensor_location: "Seis Loc:" / "Seis. Location" / "Seis Location"
/ "Sensor Location" / "Seis Loc"
To absorb future BW label drift, add a one-line dict entry — no
new elif branch.
14 new tests cover:
- Each label variant routes to the correct field (parametrised)
- Case-insensitive matching ("seis loc" / "SEIS LOC" / "SeIs LoC")
- Whitespace-collapse ("Seis Loc" with double-space)
- End-to-end parse of a real histogram fixture from
example-events/histogram/ — sensor_location ('Loc #1 - 2652 Hepner...')
populates correctly even though the file uses "Seis. Location"
Total bw_ascii_report tests: 19 → 33. Full SFM suite still green
(69 passed, 44 skipped — pre-existing skips for h5py-dep tests).
Pairs with series3-watcher v1.5.4 (which fixes the filename pairing
so histograms actually reach this parser in the first place).
Blastware's ACH writes a per-event ASCII report (.TXT) alongside each
event binary, containing the rich derived per-channel fields BW
computes (PPV, ZC Freq, Time of Peak, Peak Acceleration, Peak
Displacement, Peak Vector Sum + time, sensor self-check Pass/Fail,
monitor-log timestamps). None of this lives in the BW binary itself.
When the watcher daemon forwards both files to /db/import/blastware_file
in one multipart POST, we now:
- Pair binaries with their .TXT partners by filename match
- Parse the report into a structured BwAsciiReport
- Land the rich fields in a new top-level `bw_report` block of the
sidecar JSON
- Overlay the report's peaks/project_info/timestamp/sample_rate/
record_time/total_samples/pretrig_samples onto the canonical
sidecar fields (the report values are device-authoritative; the
BW-binary STRT-derived values had bugs like reading the 0x46
record-type marker as rectime)
This unblocks the monthly-summary review workflow — events become
sortable/filterable by peak, location, project, etc. — without
depending on the still-undecoded waveform body codec.

### Added
- **Layered event storage architecture.** Each event now lands as four
files in the per-serial waveform store, each with a clear role:
- `<filename>` — the Blastware-readable binary (BW file). Untouched.
- `<filename>.a5.pkl` — the raw 5A frames (regenerative source).
- `<filename>.h5` — clean per-channel waveform arrays in physical
units (in/s for geo, psi for mic) plus event metadata (HDF5 with
gzip compression). This is the canonical format for downstream
analysis tools.
- `<filename>.sfm.json` — the modern review/metadata sidecar (peaks,
project, source provenance, review state, extensions).
SQLite (`seismo_relay.db`) is the searchable index over all four.
- **Plot-ready waveform JSON (`sfm.plot.v1`).** The `/device/event/{idx}/waveform`
and `/db/events/{id}/waveform.json` endpoints now return samples in
physical units with explicit time-axis metadata, peak markers, and
per-channel unit hints — no more guessing the ADC-to-velocity scale
client-side. The webapp waveform viewer was rewritten to consume
this shape.
- **In-app waveform viewer accuracy fix.** The standalone SFM webapp
viewer was scaling geophone amplitudes by `geoAdcScale / 32767`
(≈ 6.206 / 32767), where `geoAdcScale = 6.206053` is the device's
*in/s per V* hardware constant — not the ADC-counts-to-velocity
factor. This silently scaled every plot ~38% too low for Normal-range
geophones (the correct full-scale is 10.0 in/s, or 1.25 in/s for
Sensitive). Conversion is now done server-side using the geo_range
from compliance config; the client just plots.
- New `sfm/event_hdf5.py` module: `write_event_hdf5()`,
`read_event_hdf5()`, plus a plot-JSON helper.
- Backfill script extended to also emit `.h5` for existing events.
### Dependencies
- Added `h5py>=3.10` and `numpy>=1.24` for the HDF5 storage layer.
- Added `python-multipart>=0.0.7` (required by FastAPI for the
`/db/import/blastware_file` endpoint introduced in this release).
- Added `waveform_key` and `event_timestamp` columns to `CachedEvent` and `CachedWaveform` for integrity verification.
- Implemented logic to flush the cache when a mismatch in (waveform_key, event_timestamp) is detected during event and waveform updates.
- Enhanced `set_events` and `set_waveform` methods to check for mismatches and trigger cache eviction as necessary.
- Introduced a new `LiveCache` class to manage in-memory caching of live device data, separating it from the server logic for better testability.
- Added tests to verify the correctness of cache invalidation logic, particularly for post-erase key reuse scenarios.
- Updated web application to include a "Force refresh" toggle, allowing users to bypass the cache and re-fetch data from the device.
