_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
