User-reported: the decoded CNTR (0x1830A44E41 ≈ 104 billion) cannot be the real counter — the OTA platform shows ~200 for that card. Root cause: per TS 102 225 Table 2 note 1, when SPI indicates ciphering the whole block from CNTR through the secured data (CNTR, PCNTR, RC/CC/DS, secured data) is ENCRYPTED. Only CPI, CPL, CHI/CHL, SPI, KIc, KID and TAR travel in the clear. Our decoder parsed the ciphertext bytes as if they were the real CNTR/PCNTR/RC and presented them as such — misleading (the true values are only recoverable after 3DES decryption with the card's keys). Fix: - _decode_secured_packet: emit 'ciphered': True when SPI1.b3 is set (wire hex values kept for reference); docstring documents the ciphered block. - _decode_response_packet: accepts ciphered (command SPI2.b5, PoR ciphering) and flags the response likewise; database context now carries por_ciphered from the ENVELOPE so the GET RESPONSE PoR inherits it. Standalone SMS-SUBMIT PoRs carry no SPI — state unknowable, defaults to False (documented). - Frontend: CNTR/PCNTR/RC-CC-DS labels get "(encrypted)" when the respective packet is ciphered (command, response, and ENVELOPE response renderings). Tests: +4 TestSecuredCiphering (ciphered flagged, unciphered plain CNTR e.g. 200, response flag, PoR-via-context). 348 total. Version 1.18.0, SW cache simtrace-analyser-v26.
