* docs: user guide, known limitations and M8 results; bump to 0.8.0v0.8.0cirakg8 days1-1/+1
| | | | | | | 0.8.0 is the release candidate: 1.0.0 is tagged after the on-watch checklist (docs/TESTING.md). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* test(build): add make watchdog, the glance memory budget and the glance ↵cirakg8 days2-0/+218
| | | | | | | | | | | | | | | screenshot - make watchdog (in make ci): a stress build encodes, packs, turns into runs and draws the largest code of every 2D symbology at two steps per event on the Forerunner 255S and 70; it fails on a watchdog trip, and the last code left on the screen must decode (bitmap path on the 70). - make memtest checks the glance (DIAG glance, budget 70 % of 64 KB). - screenshots.sh launches the app again after the flow and compares the glance with the favourite's code (glance_code.png on 7 watches); the About goldens show 0.8.0.

* feat(glance): show the favourite code in the glance (opt-in)cirakg8 days21-53/+425
| | | | | | | | | | | | | | | 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 <noreply@anthropic.com>
* fix(codes): bound every 2D encoding step under the watchdog; draw large ↵cirakg8 days9-771/+2040
| | | | | | | | | | | | | | | | | | | | | | | | | | | | codes from runs M6's step sizes were estimates, only exercised with small codes. With the largest inputs the app accepts, every 2D encoder tripped the watchdog on the Forerunner 255S (and the biggest steps were far over the 768 KB watches' limit), so a large code added from the phone would have stopped the app during settings processing at every start. - QR: resumable segmentation, Reed-Solomon, interleaving, function patterns and final mask; mask scoring on rows and columns packed 16 modules per word (same penalties, checked against the per-module rules). - Reed-Solomon: resumable field tables and generator, encoder shifting with native slice. - Data Matrix, Aztec, PDF417: resumable encodation, stuffing, compaction, placement and build; Data Matrix's grid as a byte array (90 KB -> 35 KB); PDF417 refuses text that can't fit the screen before compacting. - Cache format 2 with 16-bit sizes (wide PDF417 was cached wrong); packing in steps; codes drawn as runs, and from a bitmap painted in steps when a frame can't draw all runs. - The job runner does two steps per tick on 768 KB watches; gen_products --check verifies each product's watchdogCount fits that. - CodeView renews full brightness (AMOLED) or the backlight (MIP) for up to a minute from its single ticker; a tap restarts the minute.

* perf(import): keep parsed items packed and the pasted text oncecirakg8 days6-51/+177
| | | | | | | | | | | | | | A parsed import item with its Entry took about 760 bytes as objects on the Forerunner 255S; packed into one Codec ByteArray it takes about 110, and the importer unpacks one item per store step (wiping the packed secret). Aegis group names are resolved when unpacking, so no step repacks all items. The JSON is parsed from the untrimmed text's bytes and the string is dropped; an incomplete part is saved from those bytes. The form hash is computed before the importer copies the text. The peak of a 100-entry import on the 255S falls from 56 % to 45 %. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* feat(settings): add the Add OTP, Add code and Manage entry forms with a PIN ↵cirakg8 days15-111/+1997
| | | | | | | | | | | | | | | | | | | | queue for locked entries 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.

Google Authenticator exports deferred. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* feat(storage): add keyed secret fingerprints to record headerscirakg9 days4-1/+53
| | | | | | | | 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 <noreply@anthropic.com>
* feat(ui): add the list, OTP detail, PIN entry, menu, info screens and glancecirakg9 days20-16/+2541
| | | | | | | | | | | | 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.

* perf(crypto): XOR PBKDF2 blocks as 32-bit words and step 100 iterationscirakg9 days3-76/+76
| | | | | | | | 200 byte-wise iterations in one event tripped the 120,000-bytecode watchdog on the Forerunner 255S profile. Word-wise XOR makes PBKDF2 2.3x faster (22 ms per 1000 iterations in the simulator). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* feat(storage): add the encrypted vault, PIN keys, lockout, session and ↵cirakg10 days12-0/+1605
| | | | | | | | | | | | | | migrations 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.

| | | | | | | | Base32 accepts any case, spaces, hyphens and missing padding, and reports the exact position of a bad character. TOTP uses 64-bit time, so codes stay correct after 2038. Steam Guard is a separate, optional code type. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* feat(crypto): add SHA-512, HMAC, PBKDF2, HKDF, AES-256 records and self-testcirakg10 days10-0/+923
| | | | | | | | | | | | | | | | - Sha512: FIPS 180-4 in Monkey C (no native SHA-512), rotations inlined with precomputed masks; constants derived from the primes, not typed. - Hmac: RFC 2104 over SHA-1/256/512 (native HMAC only supports SHA-256). - Kdf: resumable PBKDF2-HMAC-SHA256 job with calibration bounds (2,000-200,000 iterations) and HKDF-SHA256. - Aes: CBC with PKCS#7 over the native cipher; AES-256 chosen. - SealedBox: encrypt-then-MAC records (HKDF-split keys, length-prefixed aad, constant-time tag check before decryption). - SelfTest: known-answer tests for every primitive at start-up. - Bytes (wipe, constant-time equal), Clock (2038-safe widening, trusted clock), Jobs (bounded steps against the watchdog, timer runner).
