Merge pull request #665 from Foundation-Devices/casa-crypto-account-export

This commit adds a new feature to Foundation's Passport hardware wallet that exports two cryptographic public keys for Casa wallet registration: the master extended public key and a separate Casa-specific key derived at path m/45'. The key…

New key-export surface: two public keys (master + m/45' derived) are now exported togetherSensitive material is public-key/chain-code only; no private keys are exportedExport channels remain QR and microSD, unchanged from prior Casa export behavior

Merge pull request #669 from Foundation-Devices/add-native-unchained-connect-wallet

This commit adds support for the Unchained wallet to the Passport hardware wallet. Most of the change is normal feature code, but it also introduces a new way to feed already-encoded data into the QR encoder and tightens up the encoder so …

New unsafe FFI function `ur_encoder_start_raw` added with documented safety preconditionsUR type string is validated (length, charset, UTF-8) before use in encoderEncoder now tracks a `started` flag and returns empty output if not started, reducing use-after-free/misuse risk

Merge pull request #655 from Foundation-Devices/sft-7320-entropy-hardening

This firmware update hardens the way Passport generates random numbers. Previously, a failing or stuck hardware random-number generator could silently produce weak or repeated values, which is dangerous for creating secret keys. The patch …

Fail-closed RNG error handling: persistent seed/clock errors now trigger a fatal handler instead of returning potentially weak valuesST-recommended seed-error recovery (RM0433 section 34.3.7): clear SEIS and flush 12 discard words, with bounded retry attemptsDuplicate and zero-value rejection in rng_try_sample to avoid returning stuck or invalid RNG output
