UI.22 The icon library: one drawing for every command, option and shell function in the eight apps, kept as data, the same in every layout and app

Owner 2026-11-09: "we need to create an entire library of icons (a task) that covers all of the application options, so that our icons are consistent regardless of the layout/app." What exists: app-workspace-icons.js holds 114 drawings on a 32-unit grid; about 270 specialist tools had no drawing by the 2026-11-05 count; the shell bar, More menu, panel tabs, status bar, menus and dialogs still use Bootstrap Icons (bi-*) and each app draws some of its own, so one command looks different from layout to layout and app to app. This row makes the library its own thing: (1) an inventory tool (tools/icons/inventory.mjs) reads every app's command registry, its toolbar, menu and toolbox definitions, the shell's bar buttons and panel tabs, Settings and the layout blocks, and writes docs/icons/INVENTORY.md: every command or option id, its apps, its drawing key or "missing"; nothing is drawn before the list exists; (2) the library in its own public repo (getcadcraft/icons, Apache-2.0, like every shared library): one SVG source per icon on the 32 grid with the five fills and two strokes as classes, names.json (key, name, aliases, the commands that use it), and a build that packs the set into app-workspace-icons.js, a sprite for the site and the add-ons kit, and the gallery data for UI.23; a hand edit of the packed file is refused by a check; (3) the drawings, under the UI.13 rules, in batches by app with the owner's look at each batch on the review sheet; shared verbs (move, copy, rotate, trim, offset, measure, zoom, undo) drawn once for every app; the shell's own set (home, find, help, settings, sun and moon, full screen, offline, problems, team, lessons, the AI and the panel buttons); (4) a lint in the release freeze: a registered command without a drawing, a drawing without a name, or a bi-* class left in shell or app chrome fails it; (5) the count in the release note (UI.18) comes from the inventory, never typed. Each app's own drawings are migrated or retired by its session.
