EL6695 8-byte bidirectional exchange with per-byte verification
- 8B PDO config: ULINT-sized payload, no 0x1A01 diag PDO on SM3
(device rejected SM3=8 with diag assigned: 'size not allowed, min/max 0xa')
- twin_layout_blob_sized(): single 64-bit mapping entry for 8B payloads
- Ticker: per-byte XOR 0x5A transform in 8B mode so TwinCAT can verify
every byte individually (1KB path unchanged, const-guarded)
- TwinCAT automation scripts: deploy with RPC retry, LinkVariables-based
whole-array relink (element links only carry 1 byte), ADS watch, diag
- Docs: 8B design, verification methodology, test report
