PORTING-BACKLOG.md

Porting backlog — Phase 1 (WebGPU), r185

Generated from research/data/files_r185.json vs src/examples.json.

214 in r185 · 198 ported · 13 excluded · 3 deferred · 0 TO PORT — Phase 1 complete.

Checkboxes are the source of truth; the counts above are hand-updated. After a wave, re-tick with node scripts/tick-backlog.mjs — anything present in src/examples.json is ported.

Category is a FIRST GUESS from the slug — the porting agent confirms it and may place the example elsewhere. Slugs drop the webgpu_ prefix and kebab-case.
