The combined `/test/soma/forms` page covered three separate components
(Switch, Checkbox, RadioGroup) in one route. Each deserves its own demo
page — matching the convention of every other component having a
dedicated `/test/soma/{kebab}` route, and letting the permutation runner
actually exercise them (the runner navigates per morfo-kebab, not per
merged page, so the combined demo left the 3 morfos SKIPPED).
## New demos
- `/test/soma/switch` — basic + disabled variants. `data-perm-step="0"`
toggles the basic switch. Axes: `dir, disabled`.
- `/test/soma/checkbox` — basic + indeterminate + group variants. Steps
0-2 toggle the first checkbox + first two group items. Seeds
`?perm.checked=true` / `?perm.value=a,b`. Axes: `dir`.
- `/test/soma/radio-group` — active + disabled variants. Steps 0-2 select
each option. Seeds `?perm.value=option-2` / `?perm.orientation`.
Axes: `dir, orientation`.
Each demo reuses the CSS from the original combined page (via `:global`
selectors for `data-switch`, `data-checkbox`, `data-radio-group-item`).
All three have `aria-label` on the Provider — the DEV-mode A4 warning
added in batch 10 of audit 2026-04-21 requires it.
The combined `/test/soma/forms` page is kept in place (pre-existing
integration demo showing composition); future batches may decide
whether to drop it or repurpose it.
## Coverage delta
- Before: 63/66 demos · 131 variants · 202 steps.
- After: 66/66 demos · 139 variants · 228 steps. (smoke: 68 routes)
Coverage complete — every morfo now has at least one instrumented demo
under the permutation runner.
## Verification
- `npm run check`: 0 errors in new demo files.
- `npm run smoke`: 68/68 routes (was 65).
- `npm run morfo:check`: 66/66 morfos.
- `npm run perm:check`: 66/66 demos · 228 steps · 139 variants.
