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.
test: add regression tests for v0.14.x SUB 5A protocol fixes
refactor(logging): change warning logs to debug for less verbosity in write_blastware_file
### 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.
test: add regression tests for v0.14.x SUB 5A protocol fixes
refactor(logging): change warning logs to debug for less verbosity in write_blastware_file
## v0.13.0 — 2026-05-01
### Fixed
- **SUB 5A bulk waveform stream — over-read bug for events ≥ 2 sec.**
`read_bulk_waveform_stream` was walking the chunk counter past the actual
end of the event, picking up post-event circular-buffer garbage that
corrupted reconstructed Blastware files for any waveform > ~1 sec. The
loop now extracts the event's `end_offset` from the STRT record at
`data[23:27]` of the probe response and stops the chunk walk when the next
counter would step past it. Verified against three BW MITM captures
(4-27-26 + 5-1-26): 2-sec event drops from 37 over-read chunks to 7
bounded chunks; 3-sec drops to 9; non-zero-start "event 2" drops to 9.
### Added
- `framing.bulk_waveform_term_v2(key4, end_offset, last_chunk_counter)` —
computes the corrected SUB 5A TERM frame's `(offset_word, params)` per the
formula confirmed across all 3 BW captures. Not yet wired into
`read_bulk_waveform_stream` (the legacy TERM is still used to preserve the
existing `blastware_file.write_blastware_file` frame-structure expectations);
available for the next iteration that switches to BW's 0x0200 chunk step.
- `framing.parse_strt_end_offset(a5_data)` — extracts the event-end pointer
from the STRT record in an A5 response payload.
Adds a new CapturingTransport wrapper in minimateplus.transport that mirrors
every TX/RX byte to two raw .bin files using the same on-wire format as
bridges/ach_mitm.py, so the resulting captures are byte-for-byte compatible
with the existing Blastware MITM captures and load directly in the Analyzer.
A new "Download" tab in seismo_lab.py lets the user connect to a device over
TCP or serial and run connect / list-keys / download-events while the wrapper
saves raw_bw_<ts>.bin (our TX) and raw_s3_<ts>.bin (device TX) into a
seismo_dl_<ts>[_<label>]/ session directory. On completion, the panel hands
both files to the Analyzer and switches tabs, mirroring the UX of the
existing Bridge capture flow.
Previously every Blastware connection auto-created files.
Now TCP mode works the same as serial mode:
- Start Bridge: proxy listens and forwards silently, no files written
- New Capture: opens raw_bw/raw_s3 files; pipe threads write to them
- Stop Capture: flushes and closes files, fires Analyzer callback
- No connection = no file; multiple captures per bridge session work correctly
https://claude.ai/code/session_014NczSHUz9uTzCAf4cVASTJ
Brings back the protocol-exp BridgePanel design:
- Single bridge session stays up; New Capture / Stop Capture create
labelled raw-file segments on demand (no files created at bridge start)
- Capture history listbox shows all segments; double-click reloads in Analyzer
- On capture complete: Analyzer auto-populates and runs analysis
TCP mode integrated into same tab (Serial/TCP radio toggle):
- Each incoming Blastware connection is automatically a capture segment
- Session appears in history list; Analyzer wires up live on connect
- Stop Capture disconnects current TCP session
https://claude.ai/code/session_014NczSHUz9uTzCAf4cVASTJ
Removes the separate 'TCP Capture' tab and folds TCP MITM capture directly
into the existing Bridge tab. A Serial/TCP radio selector at the top swaps
the connection fields (COM ports vs. listen port + device host:port) while
keeping the same Start Bridge / Stop Bridge / Add Mark buttons, capture
checkboxes, log dir, and live log — identical UX for both modes.
https://claude.ai/code/session_014NczSHUz9uTzCAf4cVASTJ
New 'TCP Capture' tab in seismo_lab.py: listens on a configurable local
port for an incoming Blastware connection, transparently forwards all
traffic to the real seismograph device, and saves both directions to
raw_bw_<ts>.bin / raw_s3_<ts>.bin in the same format the Analyzer already
understands. Session start wires up Analyzer live mode automatically via
the same on_bridge_started callback as the COM-port bridge.

Add 0x5A (BULK_WAVEFORM_STREAM) and 0xA5 (BULK_WAVEFORM_RESPONSE) to
SUB_TABLE so they display with real names instead of UNKNOWN_5A/A5.
Revert S3 checksum validation to checksum_valid=None (the original
intentional behavior). Large S3 frames (A5 bulk waveform, E5 compliance
config) embed inner DLE+ETX sub-frame delimiters; the trailing 0x03 of
the last inner delimiter can land where the parser expects the SUM8
checksum byte, causing false BAD CHK on every valid A5 frame.
protocol.py _validate_frame documents and ignores exactly this issue.
https://claude.ai/code/session_014NczSHUz9uTzCAf4cVASTJ
parse_s3 had the S3 terminator logic inverted vs the real S3FrameParser
in framing.py. It was terminating on DLE+ETX and treating bare ETX as
payload, which caused every bare 0x03 to be swallowed — bundling multiple
real S3 frames into one giant body until a DLE+ETX sequence happened to
appear. Result: 583-byte POLL_RESPONSE 'frames' containing many real
frames concatenated, all showing BAD CHK.
Fix: mirror S3FrameParser exactly —
- Bare ETX (0x03) = real frame terminator
- DLE+ETX (0x10 0x03) = inner-frame literal data (A4/E5 sub-frames),
appended to body and parsing continues
https://claude.ai/code/session_014NczSHUz9uTzCAf4cVASTJ
Frame 0 is always the probe; frames 1+ are always data (waveform ADC
chunks, compliance config, compliance continuation). Gating on
classify_frame() at fi>0 produces false positives: ADC binary data
can coincidentally contain b"STRT\xff\xfe", causing frames 1 and 5
to be silently dropped from the body (confirmed from live capture on
event key=01110000). Remove all type-based filtering; include every
frame unconditionally with the standard index-based skip amounts.
Add classify_frame() which categorises each A5 frame by content:
terminator — page_key == 0x0000
probe_or_strt — contains b"STRT"
metadata — contains compliance-config ASCII markers
(Project:, Client:, Standard Recording Setup, …)
waveform — binary-heavy (< 20% printable ASCII), i.e. raw ADC data
unknown — fallback
Update write_blastware_file() body loop: frame 0 (probe) is still
always processed; frames 1+ are only included when classify_frame
returns "waveform". Metadata frames (compliance config block with
Project:/Client:/etc.) and any stray STRT-bearing frames are skipped
with a warning/debug log. Terminator frame handling is unchanged.
Adds temporary print() diagnostics so each frame's classification is
visible in the server log to aid debugging.
