  "message": "[set] Insert coverage intersections by bitmap word\n\nCoverage format 2 now reads intersection results a word at a time, but\nstill inserted every selected glyph separately. Add an internal\nword-at-a-time set insertion path and use it when the output sink is an\nhb_set_t, preserving the generic per-glyph fallback for other sinks.\n\nThis removes another about 121M instructions from Noto Nastaliq\ndependency construction. The compile-only run now takes about 226ms\ntask-clock / 229ms elapsed and 2.83B instructions, over 2,000x faster\nthan the original 7:44.77 run.\n\nDependency graphs match the original output for Noto Nastaliq, Noto\nSans Duployan, Gulzar, Iran Nastaliq, Noto COLRv1, Amiri, and Source\nSerif Variable Roman.\n\nTested with: meson test -C build\n\nAssisted-by: OpenAI Codex \u003ccodex@openai.com\u003e\n",
