bugfix: detect RNG_SR_SEIS and RNG_SR_SECS, retry safely, and fail closed on persistent faults

This update fixes how the COLDCARD hardware wallet's random-number generator (RNG) handles rare hardware faults. Previously, the device could silently continue using weak or repeated random numbers if the RNG reported a seed error. Now it …

Why it was queued
defensive validationcryptography-sensitive pathauthentication path
AI analysis · Low 42/100

This commit adds a new user-facing verification step for BIP-322 'Proof of Reserves' messages on the COLDCARD hardware wallet. Before signing a proof-of-reserves transaction, the device now asks the user to import or type the original human-readable message, checks that it matches the cryptographic hash embedded in the transaction, and shows it on screen for approval. This is a security-hardening feature: it closes a gap where the user might otherwise sign a proof without seeing what message they are actually attesting to. The commit itself is defensive and does not appear to introduce an obvious vulnerability, but it is a partial implementation (marked with TODOs) and the change is large enough that bugs in the new input paths could affect signing safety.

AI analysis · Informational 21/100

This commit makes a small user-interface change in the COLDCARD firmware for BIP-322 proof-of-reserves signing. When the user chooses to type in the human-readable message manually, pressing Cancel on the empty text-entry screen now returns to the signing flow instead of aborting the entire operation. The change is accompanied by new tests that verify the device rejects empty or wrong messages with clear failure screens. There is no direct evidence in the commit that this fixes an exploitable security vulnerability; it appears to be a usability improvement to prevent accidental cancellation.

This commit adds support for BIP-322 Proof of Reserves signing on COLDCARD hardware wallets. It lets users prove they control certain Bitcoin addresses by signing a special non-spending transaction, without actually moving funds. The change also allows transaction version 0 only for these proof-of-reserve transactions, and blocks it for normal payments to prevent potential misuse.

This commit only adds a single line to a test file. It checks that when a user adds a BIP-39 passphrase to create a temporary seed, the COLDCARD device displays the passphrase back to the user on screen. This is a test-only change and does not modify the firmware itself. It is not a security fix or vulnerability.

AI analysis · Informational 23/100

This change makes the COLDCARD hardware wallet display the user's BIP-39 passphrase on the device's own screen after it is applied. This is a deliberate UX change, not a hidden bug. It could slightly increase the risk that someone physically near the device (or a camera) sees the passphrase, but it only appears after the user has already entered it and only on the local screen. The commit does not introduce a remote or software vulnerability.
