soma: gesture layer, drawer component, full audit fixes across 26 components
Gesture Layer:
- Gesture.base(), Gesture.drag(), Gesture.resize() — shared pointer tracking
- VelocityTracker with ring buffer, staleness check, projection
- 52 tests (velocity + gesture integration)
- setPointerCapture deferred until moveBuffer exceeded (prevents click stealing)
Drawer Component:
- 8 parts: Provider, Trigger, Content, Overlay, Handle, Title, Description, Close
- Gesture.drag() integration for swipe dismiss
- Snap points (fractional + px), fadeFromIndex, handle tap-to-cycle
- Modal/non-modal/non-dismissible modes
- Logical directions (start/end) RTL-aware via soma presentation
- CSS custom properties (--drawer-progress, --drawer-offset-x/y)
Architecture:
- T1: 219 files migrated from $soma/ alias to relative paths
- T2: 35 wrappers — noop replaced with () => {} inline
- Translation system: componentLangs + common.buttons.* + idlangref constants
- COMPONENT_GUIDE.md + README.md fully updated to reflect current patterns
- contracts.ts: case-normalized registerContract/assertContract
Audit Fixes (P0 critical):
- DI1/PO1/TO1: 'provider' → 'root' in parts/contract/super
- TB1: data-table attr on wrapper
- CH1/SW1/NF4: hidden input rendering fixes
- SP2: panel cleanup on unmount
- RG1: roving tabindex fallback to first item
- CO1: aria-labelledby on collapsible content
Audit Fixes (P1 high):
- SafePolygon integrated in dropdown-menu SubProvider + tooltip
- 9 langs.ts files with idlangref constants
- Dialog: aria-label removed (WCAG 2.5.3), handleOpen/Close guards
- Stepper: count decrement + private, aria-label on List
- ToggleGroup: roving tabindex in multiple mode
- Select: pure aria-activedescendant (no mixed focus), label registry
- NumberField: startValue respects min, scrubber commit on pointerup only
- Toolbar: element-based focus tracking (not index)
Audit Fixes (P2 medium):
- A6: timer/listener cleanup in 6 components
- A12: getDirectionalKeys in 4 components
- A10: DOM queries scoped to root in 3 components
- Dropdown-menu: typeahead + Home/End in SubContent, activate() pattern
- Checkbox: PrimitiveLabelAttributes, getAriaChecked helper, stale value cleanup
- Pagination: reactive page clamping, Set-based computePageRange
- Scroll-area: thumbSize zero-guard, mount flash prevention
- Splitter: collapse/expand respects adjacent constraints, immediate pointer capture
5 issues remain (design decisions): stepper registry, table sub-row IDs,
tags-input ARIA model, tags-input paste, toast exit animation.
