Dangerous Things 782074f6ae Initial snapshot: Aliro applet, harness, Nucleo NFC10A1 reader port
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.
