PhotoCraft scorecard

Generated by cargo xtask scorecard from perf/budgets.toml, perf/baseline.json, crates/io/tests/corpus.rs, scorecard/*.toml and the source tree. Do not edit by hand: change the sources and regenerate (CI runs cargo xtask scorecard --check). Checklist statuses are verified against the code; numbers here supersede estimates elsewhere.

Performance

Budgets: perf/budgets.toml (targets from #209, #210, #211). Numbers: the committed baseline (perf/baseline.json, full run), updated only by cargo xtask perf --update-baseline. The nightly perf-nightly workflow runs cargo xtask perf on a fixed macOS runner and fails on a broken enforced budget or a p50 regression over 15 % against a baseline from the same machine class. "Over budget" rows are targets the code doesn't meet yet: they are reported, and only their regressions fail.

Baseline: 2026-10-05, commit f5d2bcb54a, Apple M4 Pro (48 GB), GPU Apple M4 Pro, macOS 15.6; load average 224.90 / 226.31 / 196.03 (1/5/15 min) at the start of the run.

Workspace and UI

Settings that do nothing: 46 of 149 (target 0, #204). Counted by the prefs audit (xtask/src/scorecard.rs): a Preferences field counts as read when code outside the prefs model (prefs.rs except its impl Session blocks; tests excluded; the schema-driven dialog never names a field) accesses section.field, or .section and .field in the same file, or calls a section method that reads self.field. It is a heuristic lower bound: a generic name can look read when it isn't.

Unread: general.color_picker, general.beep_when_done, general.resize_image_during_place, general.always_create_smart_objects_when_placing, general.animated_zoom, general.zoom_resizes_windows, interface.dynamic_color_sliders, workspace.auto_collapse_icon_panels, workspace.auto_show_hidden_panels, workspace.enable_floating_document_window_docking, workspace.enable_narrow_options_bar, tools.enable_flick_panning, tools.vary_round_brush_hardness_on_hud, tools.show_transformation_values, file_handling.image_previews, file_handling.save_in_background, file_handling.ignore_exif_profile_tag, file_handling.maximize_psd_compatibility, performance.cache_levels, performance.legacy_compositing, scratch_disks.disks, cursors.brush_preview_color, units_and_rulers.type_units, units_and_rulers.column_width, units_and_rulers.gutter, units_and_rulers.print_resolution, plug_ins.show_extension_panels, plug_ins.allow_scripts_to_connect, plug_ins.generator_enabled, type_.smart_quotes, type_.missing_glyph_protection, type_.show_font_names_in_english, type_.text_engine, type_.font_preview, type_.recent_fonts, enhanced_controls.scrubby_slider_acceleration, enhanced_controls.touch_gestures, enhanced_controls.zoom_with_trackpad_pinch, raw_defaults.color_space, raw_defaults.bit_depth, raw_defaults.resolution, raw_defaults.sharpen_for, raw_defaults.open_as_smart_object, raw_defaults.apply_auto_tone, integrations.allow_agent_control, integrations.control_port.
