Dangerous Things

Three components, all bench-validated to varying depths: - applet/: CSA Aliro v1.0 Java Card applet for J3R180. AUTH0 + AUTH1 expedited-standard flow end-to-end green via PC/SC bench reader (aliro-bench-test). Userland AES-256-GCM and HMAC-SHA-256 layered on top of J3R180's primitives because the card lacks both natively. P-256 curve params seeded explicitly per J3R180's quirk. - harness/: Python orchestrator (aliro-trustgen, aliro-personalize, aliro-bench-test) for trust-bundle generation, card personalization via PersonalizationApplet, and PC/SC AUTH0+AUTH1 transactions. 126 pytest cases passing. - reader/STM32CubeExpansion_ALIRO_V1_0_0/: ST X-CUBE-ALIRO V1.0.0 with our NFC10A1 port (NUCLEO-U545RE-Q + X-NUCLEO-NFC10A1, ST25R200 shared with NFC09A1). nfc10-only/ project, NFC10A1 BSP shim, ALIRO_TRUST_OVERRIDE include into vendor's provisioning.c, and an ALIRO_APDU_TRACE wrapper around demoTransceiveBlocking. Boots, detects the J3R180, completes SELECT + AUTH0; AUTH1 currently fails with RFAL ERR_PROTO (0xB) — under investigation, see docs/plans/2026-04-20-nucleo-nfc10a1-port.md and bench-notes/. Excluded: x-cube-aliro.zip vendor archive, harness/.venv, build dirs, generated aliro_trust.h (contains private reader scalar), all PEMs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
