1// verify_passkey.mjs — enrol a passkey and unlock with it, end to end.
2//
3// Drives the REAL unlock and Settings UI in Chromium, with a CDP *virtual
4// authenticator* standing in for a platform authenticator (Touch ID / Windows
5// Hello). The flow:
6//
7// create an identity → enrol a passkey from Settings → lock →
8// unlock with the passkey button → assert the app is unlocked
9//
10// and it checks the sealed passphrase blob is written under the account's own
11// namespace (accounts.js prefixes every daimond-* key; the primary keeps the
12// raw name).
13//
14// LIMITATION — the WebAuthn PRF extension must be honoured by the virtual
15// authenticator for the full unlock to run. Chromium's virtual authenticator
16// supports PRF (via hmac-secret) for a ctap2 + resident-key + user-verification
17// device, which is how it is configured below (with a couple of option
18// fallbacks across Chromium versions). Where a given build does NOT surface
19// PRF, enrolment reports it and writes no blob; this script then FALLS BACK to
20// asserting the capability probe and the UI paths, and says so, rather than
21// failing a test the engine cannot support. A written blob means PRF worked and
22// the lock/unlock round trip is asserted in full.
23//
24// Exits non-zero on any hard failure.
