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.
