feat(pin): exactly 4 digits, entered on the 4th digit

2026-10-25T11:46:42+00:00

The keypad has no OK key; the 4th digit submits, so a tap that also arrives as START can no longer submit a partial PIN (the likely cause of "Wrong PIN" before the code opened). PINs set by earlier versions still unlock and are then replaced by a 4-digit one. Opening an entry ignores a second request from the same tap. A Require PIN sent from the phone while the watch is locked now applies at the next PIN instead of waiting for Confirm all. The linter skips .claude. Co-Authored-By: Claude Opus 5.5

feat(glance): show the favourite code in the glance (opt-in)

2026-10-21T01:55:10+00:00

With "Show the favourite code in the glance" on, the glance shows the code of the first favourite TOTP or Steam entry without the PIN, with a countdown bar. The glance can't open the vault, so the About scan seals that entry under "g" (device key, aad OTPW-GL-1) after every change, and removes it when the option is off or no entry qualifies; the glance also reads the option itself. HKDF moves to its own module so the glance loads only the crypto it needs (37 % of its 64 KB). Manage entry gains "Mark as favourite (glance)" and "Remove favourite", queued for locked entries like the other changes. Lines are inset on round screens so the Instinct 3's curved glance corner doesn't cut them. Co-Authored-By: Claude Opus 5.5

feat(settings): add the Add OTP, Add code and Manage entry forms with a PIN queue for locked entries

2026-10-20T16:36:54+00:00

The full phone settings form (README 10.2) and its processing (10.3) as one resumable job: Import, Add OTP, Add code, Manage, then the About fields. Forms are applied only when their switch is on, cleared afterwards (secret first; only the secret after a problem), deduplicated by keyed hash, and report into their Result field and the results screen. - Add OTP validates per README 10.4; Add code runs the real encoder (CodeCheck, a job for 2D codes) and caches 2D codes on the way in. - Manage entry: edit, move, require/drop PIN, replace, counter, delete. Changes to locked entries are sealed under "q" and applied only after the PIN is entered under "Phone changes" in the menu. - About: catalog (800 characters max), version, storage use. - "Encrypt names" now applies to new and existing entries.

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(ui): add the list, OTP detail, PIN entry, menu, info screens and glance

2026-10-19T20:28:09+00:00

List with live codes and countdowns, adaptive rows and lazy headers; OTP detail with ring or bar, next code and HOTP next; PIN keypad or button selector with create, unlock, change, lockout display and pending promotion; native menu; glance with the entry count; self-test after the first frame; option properties with defaults. Codes are computed one per timer event, apart from drawing, for the watchdog. A UI-test build (uitest.jungle) starts with fake entries, PIN 123456 and a frozen clock. 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.
