sfm/database.py (new)
- SeismoDb class: three tables keyed by unit serial number
- ach_sessions: one row per ACH call-home
- events: one row per triggered event, deduped by (serial, waveform_key)
- monitor_log: one row per monitoring interval, deduped by (serial, waveform_key)
- WAL mode, per-request connections, silent dedup via UNIQUE constraint
- Query helpers: query_events(), query_monitor_log(), get_sessions(), query_units()
- false_trigger flag on events for future review UI / report filtering
bridges/ach_server.py
- Import SeismoDb; create shared instance at startup pointed at
bridges/captures/seismo_relay.db
- After each call-home: insert_events() + insert_monitor_log() + insert_ach_session()
- DB failures logged as warnings, never abort the session
sfm/server.py
- Import SeismoDb; lazy singleton via _get_db()
- New DB read endpoints: GET /db/units, /db/events, /db/monitor_log, /db/sessions
- PATCH /db/events/{id}/false_trigger for manual review flagging
CLAUDE.md / CHANGELOG.md
- Document DB schema, SFM DB endpoints, architecture decision (unit-keyed only)
- Version bump to v0.11.0

Add full decode pipeline for 0x2C partial records from the device's event
list, representing continuous monitoring intervals where no threshold was
crossed. These records appear interleaved with full triggered events in the
browse walk and were previously ignored.
minimateplus/models.py
- Add MonitorLogEntry dataclass: key, start_time, stop_time, serial,
geo_threshold_ips, raw_header, duration_seconds property
minimateplus/protocol.py
- read_waveform_header() now returns (data_rsp.data, length) — full payload
including the record-type byte at position 0 — instead of the sliced header.
Callers that need the old slice use raw_data[11:11+length] as before.
minimateplus/client.py
- Add _decode_0a_partial_header(): auto-detects 9-byte (sub_code=0x10) vs
10-byte (sub_code=0x03) timestamp format, handles 1-byte inter-timestamp
gap, extracts serial via BE anchor and geo threshold via Geo: anchor.
- Add get_monitor_log_entries(skip_keys=None): browse walk (1E → 0A → 1F),
decodes partial records, skips full records and already-seen keys.
minimateplus/__init__.py
- Export MonitorLogEntry
bridges/ach_server.py
- After get_events(), call get_monitor_log_entries(skip_keys=seen_keys) and
save new entries to monitor_log.json in the session directory.
- Add _monitor_log_entry_to_dict() helper.
- Include monitor log keys in downloaded_keys for state persistence.
CLAUDE.md / CHANGELOG.md
- Document 0x2C partial record layout (timestamp format, ASCII metadata
region, 1-byte gap edge case) confirmed from 4-11-26 MITM capture.
- Version bump to v0.10.0; update What's next.

Listens for inbound unit connections, connects upstream to a real Blastware
ACH server, and forwards bytes bidirectionally while saving both directions to
raw_bw_<ts>.bin and raw_s3_<ts>.bin in the existing capture format.
Used to capture the 4-11-26 Blastware ACH session that confirmed the erase-all
protocol (SUBs 0xA3/0x1C/0x06/0xA2) and the event deletion wire sequence.
Usage:
python bridges/ach_mitm.py --bw-host 127.0.0.1 --bw-port 9999 --listen-port 9998
Point the unit's call-home destination at this machine:9998.
Point this proxy's --bw-host/port at the upstream Blastware ACH server.

State format (ach_state.json):
- Replace event_count with downloaded_keys (set of hex strings) + max_downloaded_key
- Key-based tracking correctly handles delete-then-re-record: after device erase the
count drops to 0, but new events have new (or recycled) keys
Browse pre-check:
- list_event_keys() walk before get_events() to bail early when nothing is new
- get_events() called with skip_waveform_for_keys= for already-seen keys, so repeat
call-homes only download waveforms for genuinely new events
--clear-after-download flag:
- After saving new events, calls client.delete_all_events() (0xA3→0x1C→0x06→0xA2)
- On success: resets downloaded_keys=[] and max_downloaded_key="00000000" so the
next session starts fresh (device counter resets to 0x01110000 after erase)
Post-erase key-reuse detection:
- Device counter resets to 0x01110000 after any erase; new events reuse old keys
- If max(device_keys) < max_downloaded_key, the device was wiped externally
(Blastware, manual) — seen_keys is discarded and all device keys treated as new

Event model uses peak_values (not peaks) and project_info (not direct fields).
PeakValues fields are tran/vert/long/micl/peak_vector_sum (not transverse etc).
ProjectInfo fields accessed via ev.project_info.project etc.
Also fix ev.timestamp serialization: use str() instead of .isoformat() since
Timestamp is a custom dataclass, not datetime.

calibration_date, aux_trigger, setup_name etc. don't exist directly on
DeviceInfo — they live in DeviceInfo.compliance_config (ComplianceConfig).
_device_info_to_dict now accesses them via cc = d.compliance_config.
Log line updated to show serial/firmware/model/event_count instead.

socket.accept() on Windows blocks indefinitely and ignores KeyboardInterrupt.
Setting a 1-second timeout on the server socket causes the accept loop to wake
up every second and re-check, so Ctrl-C is handled within ~1 second.

- Session directory and log file are now created ONLY after startup() succeeds.
Internet scanners and dropped connections no longer litter the output folder.
Raw bytes are buffered in memory until startup succeeds, then flushed to disk.
- Add --allow-ip IP flag (repeatable) to allowlist specific source IPs.
Connections from un-listed IPs are rejected immediately (socket closed, no log).
If no --allow-ip flags are given, all IPs are still accepted (original behavior).
Usage: --allow-ip 63.43.212.232 --allow-ip 152.1.2.3

_decode_event_count: read uint16 BE at offset 10 (confirmed 2026-04-10 from
live BE11529 event index — data[10:12]=0x0006=6, matches device LCD).
Previous uint32 at offset 3 always returned 1 regardless of event count.
ach_server.py: use device_info.event_count (already fetched during connect())
instead of calling count_events() separately. This saves 2*N round-trips and
avoids the 1F linked-list walk which was overcounting on some devices.
count_events() kept as fallback when connect() is skipped (--events-only).

- Replace all Unicode arrows/checkmarks (-> [OK] [FAIL]) in ach_server.py
and client.py log calls — Windows cp1252 console can't encode them
- Fix DeviceInfo attribute: serial_number -> serial
- Fix _device_info_to_dict key: serial_number -> serial
- Demote count_events 1E/1F per-key log lines from WARNING to DEBUG
(they were flooding the console on devices with many stored events)
- FileHandler now opens with encoding='utf-8' so session log files
can hold any characters without codec errors

ach_server.py:
- Add ach_state.json per-unit state tracking (keyed by serial number)
- count_events() before any download; skip session if no new events since last call-home
- Download only events beyond the previous high-water mark (all_events[last_count:])
- --max-events N safety cap for first-run units with many stored events
- state_path and max_events wired through AchSession constructor and serve()
client.py (_decode_monitor_status):
- Revert monitoring flag to section[1] == 0x10 (was incorrectly changed to section[6])
- Fix battery/memory offsets to section[-10:-8], [-8:-4], [-4:] (no trailing checksum byte)
- Both confirmed by full byte diff of all 144 0xE3 data frames in 4-8-26/2ndtry capture

minimateplus/transport.py:
- Add SocketTransport(TcpTransport) — wraps an already-accepted inbound
socket; connect() is a no-op; everything else inherited from TcpTransport.
Enables the ACH server to reuse all existing protocol/client code without
any changes.
bridges/ach_server.py:
- Minimal inbound ACH server — listens on port 12345, accepts call-home
connections from MiniMate Plus units, runs the full BW protocol:
startup handshake → get_device_info → get_events(full_waveform=True)
- Saves device_info.json + events.json + raw_rx_<ts>.bin + session log
per connection to bridges/captures/ach_inbound_<ts>/
- raw_rx.bin is byte-compatible with existing Analyzer tooling
- Taps transport.read() to capture raw S3 bytes alongside parsed output
- Each connection runs in its own daemon thread
- Clearly distinguishes push vs pull protocol in the startup log

Adds a production-safe headphone-splitter mode:
- Device bytes tee'd to both --upstream (primary/prod) and --mirror (new server)
- Only primary server responses are returned to the device
- Mirror connect/write failures are non-fatal and logged; prod is unaffected
- New raw_mirror_<ts>.bin capture file alongside raw_client/raw_server
Three modes: standalone (capture only), bridge (one upstream), splitter (two).
Default listen port changed to 12345 to match project ACH setup.

- bridges/ach_bridge.py: transparent TCP bridge that MITMs the MiniMate Plus
call-home connection — forwards to real ACH server while logging all frames
to raw_client/raw_server .bin files compatible with parse_capture.py;
standalone capture mode for lab use without a real server
- bridges/serial_watch.py: RS-232 serial monitor with live S3 frame parsing;
taps the line between MiniMate and modem (RV50/RV55); captures raw bytes,
.log and .jsonl; --ack-ok mode auto-replies to AT commands; fixed fatal
indentation bug in the original that silently prevented any data capture
- seismo_lab.py: new "Serial Watch" fourth tab (SerialWatchPanel) wrapping
serial_watch.py functionality; COM port picker with refresh, baud config,
ack-ok toggle, colour-coded live frame log (teal frames / yellow ctrl /
blue AT), raw .bin capture auto-fed into Analyzer tab on stop

- bridges/tcp_serial_bridge.py: increase default boot_delay 2s → 8s to
cover MiniMate Plus cold-start time (unit wakes from RS-232 line
assertion but takes 5-10s to be ready for POLL_PROBE).
- sfm/server.py: add _run_with_retry() — on TCP connections only, retries
once on ProtocolError. Serial timeouts are not retried (usually a real
fault). Confirmed behaviour: unit wakes purely from RS-232 line voltage,
no software wake-up frame needed.
