test(build): add make watchdog, the glance memory budget and the glance screenshot

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

- 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.

fix(codes): bound every 2D encoding step under the watchdog; draw large codes from runs

2026-10-21T01:55:01+00:00

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.

build(lint): validate resource XML against the SDK schema and cross-check the settings form

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

tools/check_resources.py checks every resource file against the SDK's resources.xsd and that settings, properties and strings agree. Adds the pure-Python, MIT-licensed xmlschema to the dev image. Co-Authored-By: Claude Opus 5.5

test(codes): compare Aztec with aztec_code_generator, decode it and its screenshot
