Decode errors now log to stderr instead of crashing the entire
API response. This prevents a single malformed message from hiding
all subsequent messages in the same query.
decode_sniff_msg() dispatches to type-specific decoders:
- change: 4-byte flags bitmask → card insert/eject/reset/timeout
- fidi: 1-byte Fi/Di index → decoded values
- atr/pps: raw hex value
database.py now decodes all message types, not just tpdu.
Pure Python, no dependencies. Decodes raw TPDU bytes into
structured JSON: CLA bitfield, INS->name via APDU_SPEC table,
P1/P2 field breakdown, body extraction, SW name lookup.
~40 command types, 40+ SW codes, known FID notes.
database.py: _row_to_message() calls decode_message() for tpdu
messages, adding 'decoded' field to API responses.
Decoding happens at query time, not storage time — no schema
migration, all past sessions get decode retroactively.
Add simtrace2-pysniff-server CLI — HTTP API for simtrace-analyser PWA.
Two capture modes: GSMTAP UDP listener (compatible with simtrace2-sniff)
or direct SIMtrace2 hardware capture. SQLite storage with sessions +
messages tables. REST API with CORS.
server/ sub-package: database.py, capture.py, server.py, __main__.py
README updated with server usage section.
pyproject.toml: simtrace2-pysniff-server script entry added.
