fix(pin): the work after a PIN and the change queue run in steps

2026-10-27T00:01:18+00:00

After a correct or new PIN, promoting pending entries and applying waiting "Require PIN" changes ran in the event of the last PBKDF2 step; 16 waiting changes tripped the watchdog on the Forerunner 70. ChangeQueue.LockJob now does it in steps while the PIN screen shows "Checking...", saves what it did to the results and refreshes the glance after Set PIN too. The list title decrypted every waiting change at each start. Queue items are now [action, box] (aad OTPW-Q-2 + action code), so they are counted without decrypting; 0.9.0 items are still read. A replacement is checked when it arrives and its material is sealed apart (qm.). Large buffers are wiped and UTF-8-checked in pieces (Jobs.Wiper, Bytes.utf8Prefix, SealedBox.openKeep/sealKeep). "Phone changes" reads behind "Reading...", and Confirm all / Reject all act only on the changes shown. Storage full no longer stops the app at the PIN. Found by the review of b8addc8/096b5a4 and a new make watchdog test; the diff was reviewed again and its findings fixed. fr70: make lint, make test (176), make watchdog (19 cases at two steps per event), make screenshots pass; list_locked and list_reset goldens show "Results ready (menu)".

feat(storage): add keyed secret fingerprints to record headers

2026-10-19T23:51:05+00:00

An 8-byte HMAC of kind, type and secret (key derived from the device key) in header tag 13 lets imports find duplicates of locked entries while the watch is locked. Vault gains anyHeader() and storage(). Co-Authored-By: Claude Opus 5.5

feat(storage): add the encrypted vault, PIN keys, lockout, session and migrations

2026-10-19T13:27:37+00:00

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.
