* feat(storage): add the encrypted vault, PIN keys, lockout, session and ↵cirakg10 days1-0/+60
| | | | | | | | | | | | | | migrations Records are one ByteArray each: a readable TLV header plus an encrypt-then-MAC box whose aad binds the entry ID and the header. The device key seals unlocked entries and pending items; a random master key, wrapped under a PBKDF2 PIN key, seals locked ones. Wrong PINs are counted before the check, with delays on the trusted clock and an uptime fallback. Bytes.toUtf8 validates UTF-8 first, because the native conversion crashes on invalid input.

* feat(crypto): add SHA-512, HMAC, PBKDF2, HKDF, AES-256 records and self-testcirakg10 days3-0/+228
| | | | | | | | | | | | | | | | - Sha512: FIPS 180-4 in Monkey C (no native SHA-512), rotations inlined with precomputed masks; constants derived from the primes, not typed. - Hmac: RFC 2104 over SHA-1/256/512 (native HMAC only supports SHA-256). - Kdf: resumable PBKDF2-HMAC-SHA256 job with calibration bounds (2,000-200,000 iterations) and HKDF-SHA256. - Aes: CBC with PKCS#7 over the native cipher; AES-256 chosen. - SealedBox: encrypt-then-MAC records (HKDF-split keys, length-prefixed aad, constant-time tag check before decryption). - SelfTest: known-answer tests for every primitive at start-up. - Bytes (wipe, constant-time equal), Clock (2038-safe widening, trusted clock), Jobs (bounded steps against the watchdog, timer runner).

* feat(app): add minimal watch app with smoke test and per-size iconscirakg10 days1-0/+50
The M0 placeholder app: AppBase entry point, home screen with name and version, debug-only diagnostics (start-up time, memory) and a unit test that runs in the headless simulator. Builds with strict type checking and zero warnings for all 72 products; icons.jungle gives every product a launcher icon of its exact size. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
