Building a shape out of simpler ones meant drawing the result point by
point. The Vector Art tab now selects several shapes at once and
combines them with a boolean operation into one ordinary shape.
- Ctrl/Cmd+click in the tab and Ctrl or Shift+click in the shape list
add a shape to the selection. Shift stays pan in the canvas.
- A COMBINE block in the inspector offers Union, Subtract, Intersect
and Exclude. Subtract removes every upper shape from the lowest one.
- The result replaces the lowest selected shape and keeps its name,
colours, stroke and place in the order. It is one undo step.
- Curves are flattened to 0.2 canvas pixels, a circle gets about 48
points. Open lines and single shapes cannot be combined, the buttons
are off and a hint gives the reason. An empty result is rejected.
- Delete now removes every selected shape, and the selection drops
shapes that no longer exist.
- The geometry comes from clipper2-ts 2.0.1, pinned. It has no
dependencies and speaks even-odd directly. Only the engine module
is imported, the bundle grows by 55 kB instead of 110 kB.
Findings:
- clipper2-js was tried and dropped. It pulls in Angular 15 with a
high npm audit finding and no fix.
- Pixi finds holes by containment, not by even-odd depth. An island
inside a hole would be drawn as a hole again. Result rings are
emitted outer ring before its islands, and a test mirrors Pixi's
rule.
- A depth sort turned out to be dead code in a counter-check and was
removed. A pixel check in 47h stayed green without the subtract
and now checks both colours.
Tests:
- ./check.sh: 134 files, 1986 tests, exit 0 (before 133 / 1968)
- npm run build: exit 0
- GM_STEPS=47, freshly seeded: ALL PASSED, 44 checks (before 39)
- 18 new unit tests, 5 new e2e checks in block 47h
- Five counter-checks bite, originals restored and verified with cmp
- Check sum 1222 in README and wiki, calculated (1217 + 5)

Tooling:
- Prettier as the single formatting authority (110 columns, single quotes,
measured against the existing style); Markdown excluded because table-cell
padding turns the README glossary into 1000-character lines.
- Type-aware ESLint ending in eslint-config-prettier, so a rule always means
"this is a bug", never "this looks different".
- .editorconfig and an `npm run check` that runs typecheck, lint, format and
tests in one go.
Findings fixed on the first run: three more duplicate imports, four
String(unknown) calls (parameter types narrowed instead of casts), two dead
initialisers, two redundant casts, a console.log for a real error. Two
warnings were false here and are disabled with a reason in place.
Tests 132 -> 269:
- node-catalog.test.ts covers every node with a run(), with a guard that fails
when a new node has no row.
- behavior-events.test.ts covers the ten event nodes through a running World,
checking timing rather than existence.
- Input's state machine (press/release/releaseAll) is reachable without DOM
events now; the DOM handlers are thin adapters.
Compare fell back to == without a configured operator although the schema
default is <; aligned.
