Project scaffold (uv, pyproject.toml CalVer 2026.5.10, ruff, pytest, mypy
strict config, MIT, README, .gitignore protecting any .pca / panel keys).
Library primitives (src/omni_pca/):
- crypto.py AES-128-ECB + per-block XOR seq pre-whitening, session-key
derivation (CK[0:11] || (CK[11:16] XOR SessionID))
- opcodes.py Byte-exact PacketType (12), v1 MessageType (104),
v2 MessageType (83), ConnectionType, ProtocolVersion
- packet.py Outer Packet dataclass with encode/decode
- message.py Inner Message + CRC-16/MODBUS, helpers for v1/v2
- pca_file.py Borland LCG XOR cipher, PcaReader, .pca + .CFG parsers
(KEY_PC01 = 0x14326573, KEY_EXPORT = 0x17569237 — fixed
from initial typo; verified via test_keys_match_decompiled)
- __main__.py CLI: 'omni-pca decode-pca <file> --field {host,port,...}'
PII opt-in via --include-pii
49 tests pass, 1 skipped (live fixture). Ruff clean.
