- Added `CallHomeConfig` model to represent the Auto Call Home settings.
- Introduced methods in `MiniMateClient` for reading (`get_call_home_config`) and writing (`set_call_home_config`) the call home configuration.
- Updated `MiniMateProtocol` with new commands for call home operations (SUB 0x2C for read, SUB 0x7E for write, and SUB 0x7F for confirm).
- Created API endpoints for retrieving and updating call home settings in the server.
- Enhanced the web interface with a new "Call Home" tab for user interaction with call home settings.
- Implemented JavaScript functions for reading and writing call home configurations from the web app.
Ports the intelligent-caching branch concept to a plain Python in-memory
implementation — no SQLAlchemy, no extra DB table, no new dependencies.
_LiveCache (threading.Lock + dicts) caches:
- device info: indefinite, invalidated by POST /device/config
- events: keyed by (conn_key, device_event_count); count-probe fast path
(~2s poll+count_events) avoids full downloads when nothing is new
- monitor status: 30-second TTL, invalidated by monitor start/stop
- waveforms: permanent per (conn_key, event_index)
All four cached endpoints accept ?force=true to bypass the cache.
Removes sfm/cache.py (SQLAlchemy experiment, now superseded).

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

Introduces sfm/cache.py — a SQLite-backed cache (via SQLAlchemy) that
sits between the SFM REST endpoints and the device, eliminating redundant
cellular downloads for data that doesn't change.
Cache behaviour by data type:
- Device info / compliance config: cached until a config write occurs;
POST /device/config now calls mark_config_dirty() to force a fresh read
on the next /device/info call.
- Event headers + peak values: cached permanently (append-only). On
subsequent calls to /device/events, the server does a fast count_events()
(~2s) instead of a full download (~10-30s); only new events are fetched
from the device and merged into the cache.
- Full waveforms (raw ADC samples): cached permanently — immutable once
recorded. Repeated requests for the same waveform return instantly with
zero device contact.
- Monitor status (battery, memory, is_monitoring): 30-second TTL; auto-
invalidated on start/stop monitoring commands.
All endpoints gain a ?force=true param to bypass the cache when needed.
New endpoints: GET /cache/stats, DELETE /cache/device.
Adds requirements.txt listing fastapi, uvicorn, sqlalchemy, pyserial.

section[6] is the monitoring flag (was wrongly section[1] — section[1] is always
0x00 in both states). Battery and memory fields use relative-from-end offsets
(section[-11:-9], section[-9:-5], section[-5:-1]) instead of absolute positions,
which broke when the payload grew by 3 bytes in monitoring mode.
Confirmed from full byte diff of 142 0xE3 frames in 4-8-26/2ndtry capture.
SFM start_monitoring now polls /device/monitor/status every 5s for up to 60s
instead of a fixed 25s delay (unit runs ~40s on-device sensor check before
confirming monitoring state).
Also corrects stale 1C→6E response anomaly claim in protocol reference — no
exceptions to the 0xFF−SUB rule are known.
- Introduced new SUBs for monitoring status, start, and stop commands in protocol.py.
- Implemented read_monitor_status, start_monitoring, and stop_monitoring methods in MiniMateProtocol class.
- Added new API endpoints for monitoring status retrieval and control in server.py.
- Enhanced the web application with a monitoring panel, including battery and memory status display.
- Created a new Python script to parse SUB 0x1C response frames for monitoring status.
- Documented the monitoring status response format and field locations in markdown and text files.
Two improvements to eliminate the ~2-min-per-event wait and unnecessary
full-event-list download when only one event is requested:
1. protocol.py: pass timeout=10.0 to _recv_one in the 5A chunk loop.
Device responds within ~1s per chunk; 10s gives a safe 10x buffer.
End-of-stream detection (raw_bytes=1) now fires in 10s instead of 120s,
cutting ~110s of dead wait per event.
2. client.py: add stop_after_index parameter to get_events(). When set,
iteration stops immediately after the target event is collected — no
further 0A/1E/0C/5A/1F cycles for events the caller doesn't need.
3. server.py: pass stop_after_index=index to both /device/event/{idx}
and /device/event/{idx}/waveform endpoints so a single-event request
only downloads that one event.
