Reverse-engineered the full Blastware 4-frame sequence for SUB 1A:
A (probe): offset=0x0000, params[7]=0x64
B (data req 1): offset=0x0400, params[2]=0x00, params[7]=0x64 → bytes 0..1023
C (data req 2): offset=0x0400, params[2]=0x04, params[7]=0x64 → bytes 1024..2047
D (data req 3): offset=0x002A, params[2]=0x08, params[7]=0x64 → bytes 2048..2089
We were only sending A+D and getting 44 bytes (the last chunk).
Now sends B, C, D in sequence; each E5 response has 11-byte echo header
stripped, and chunks are concatenated. Devices that return all data in
one frame (BE18189 style) are handled — timeouts on B/C are skipped
gracefully and data from D still accumulates.
Total expected: 0x0400 + 0x0400 + 0x002A = 0x082A = 2090 bytes.

BE11529 sends the compliance config (SUB 1A / E5 response) as a stream
of small frames (~44 bytes each) rather than one large frame like BE18189.
Changes:
- read_compliance_config(): loop calling _recv_one() until 0x082A bytes
accumulated or 2s inter-frame gap; first frame strips 11-byte echo header,
subsequent frames logged in full for structure analysis
- _recv_one(): add reset_parser=False option to preserve parser state and
_pending_frames buffer between consecutive reads from one device response;
also stash any extra frames parsed in a single TCP chunk so they are not lost

The heuristic offsets for trigger/alarm levels were causing struct unpack
errors. These fields require detailed field mapping from actual E5 captures
to determine exact byte positions relative to channel labels.
For now, skip extraction and leave trigger_level_geo/alarm_level_geo as None.
This prevents the '500 Device error: bytes must be in range(0, 256)' error.
Once we capture an E5 response and map the exact float positions, we can
re-enable this section with correct offsets.

Adds full support for reading device compliance configuration (2090-byte E5
response) containing record time, trigger/alarm levels, and project strings.
protocol.py:
- Implement read_compliance_config() two-step read (SUB 1A → E5)
- Fixed length 0x082A (2090 bytes)
models.py:
- Add ComplianceConfig dataclass with fields: record_time, sample_rate,
trigger_level_geo, alarm_level_geo, max_range_geo, project strings
- Add compliance_config field to DeviceInfo
client.py:
- Implement _decode_compliance_config_into() to extract:
* Record time float at offset +0x28 ✅
* Trigger/alarm levels per-channel (heuristic parsing) 🔶
* Project/setup strings from E5 payload
* Placeholder for sample_rate (location TBD ❓)
- Update connect() to read SUB 1A after SUB 01, cache in device_info
- Add ComplianceConfig to imports
sfm/server.py:
- Add _serialise_compliance_config() JSON encoder
- Include compliance_config in /device/info response
- Updated _serialise_device_info() to output compliance config
Both record_time (at fixed offset 0x28) and project strings are ✅ CONFIRMED
from protocol reference §7.6. Trigger/alarm extraction uses heuristics
pending more detailed field mapping from captured data.
Sample rate remains undiscovered in the E5 payload — likely in the
mystery flags at offset +0x12 or requires a "fast mode" capture.

Confirmed 2026-04-01 against Blastware event report for BE11529 thump
event ("00:28:12 April 1, 2026", PVS 3.906 in/s).
models.py:
- Timestamp.from_waveform_record(): decode 9-byte format from 0C record
bytes[0-8]: [day][sub_code][month][year:2BE][?][hour][min][sec]
- Timestamp: add hour/minute/second optional fields; __str__ includes
time when available
- PeakValues: add peak_vector_sum field (confirmed fixed offset 87)
client.py:
- _decode_waveform_record_into: add timestamp decode from bytes[0:9]
- _extract_record_type: decode byte[1] (sub_code), not ASCII string
search; 0x10 → "Waveform", histogram TBD
- _extract_peak_floats: add PVS from offset 87 (IEEE 754 BE float32)
= √(T²+V²+L²) at max instantaneous vector moment
sfm/server.py:
- _serialise_timestamp: add hour/minute/second/day fields to JSON
- _serialise_peak_values: add peak_vector_sum to JSON
docs: update §7.7.5 and §8 with confirmed 9-byte timestamp layout,
PVS field, and byte[1] record type encoding; update command table;
close resolved open questions.

- _decode_serial_number: read from data[11:] not data[:8] — was returning
the LENGTH_ECHO byte (0x0A = '\n') instead of the serial string
- _extract_peak_floats: search for channel label strings ("Tran" etc) and
read float at label+6; old step-4 aligned scan was reading trigger levels
instead of PPV values
- get_events: add debug=False param; stashes raw 210-byte record on
Event._raw_record when True for field-layout inspection
- server /device/events: add ?debug=true query param; includes
raw_record_hex + raw_record_len in response when set
- models: add Event._raw_record optional bytes field
- minimateplus/transport.py: add TcpTransport — stdlib socket-based transport
with same interface as SerialTransport. Overrides read_until_idle() with
idle_gap=1.5s to absorb the modem's 1-second serial data forwarding buffer.
- minimateplus/client.py: make `port` param optional (default "") so
MiniMateClient works cleanly when a pre-built transport is injected.
- minimateplus/__init__.py: export SerialTransport and TcpTransport.
- sfm/server.py: add `host` / `tcp_port` query params to all device endpoints.
New _build_client() helper selects TCP or serial transport automatically.
OSError (connection refused, timeout) now returns HTTP 502.
- docs/instantel_protocol_reference.md: add changelog entry and full §14
(TCP/Modem Transport) documenting confirmed transparent passthrough, no ENQ
on connect, modem forwarding delay, call-up vs ACH modes, and hardware note
deprecating Raven X in favour of RV55/RX55.
Usage: GET /device/info?host=<modem_ip>&tcp_port=12345
