Close the Phase 1b debt: the "## Handoff 2026-05-14" blocks embedded at
the top of arts/README, arts/adom/README and arts/format/README move to
docs/process/handoffs-2026-05.md, so the layer references read as
timeless. Same mechanical pattern already applied to the UIX READMEs in
41c3b0f9.

Add `raf(callback, node?): ActiveDomFrameCleanup` to the ActiveDom surface —
a one-shot animation frame that returns an idempotent **disposer** (the same
`() => void` shape as `listen` / `observe*`), so an `$effect` can
`return dom.raf(...)` and Svelte cancels the pending frame on teardown. It
wraps the existing `requestFrame` / `cancelFrame` (which already resolve the
instance's `targetWindow` — iframe / popup / happy-dom safe), adding no new
scheduling logic. New `ActiveDomFrameCleanup` type exported from the barrel;
`raf` also implemented on the disabled-dom stub (throws, like `requestFrame`).
Why: the doctrine is "all DOM activity via ActiveDom". `listen`/`observe*`
already returned disposers; the animation frame was the gap — `requestFrame`
exposes a raw numeric handle (per-call bookkeeping + leak risk), and layout
components were falling back to the GLOBAL `requestAnimationFrame`, which
targets the wrong window in iframe/popup contexts (the exact bug getWindow/
getDocument fix elsewhere). `raf` closes it.
Migrated the 3 raw `requestAnimationFrame` sites the Words audit surfaced —
words-block-gutter (reposition), words-bubble-menu + words-slash-menu
(overlay position) — to `dom.raf(...)`. Bubble/slash keep their `tick()`
fallback for no-rAF environments.
Documented the decision + rationale as a dated Backlog entry at the end of
`src/arts/adom/README.md` (and listed `raf` in the API + imperative-actions
sections). Notes the kept distinction: `raf` is for layout frames, NOT the
`$timer` lifecycle scheduler; low-level requestFrame/cancelFrame stays for
consumers that already hold the handle (drawer/slider/splitter/floating/
focus-scope). Remaining raw rAF in other eidos components (tabs-indicator…)
left for when those are touched — flagged in the backlog.
Gates: npm run check 1 error (pre-existing grafito, not adom/Words) · soma
words + adom 479/479 · prettier clean · browser smoke: gutter repositions,
bubble menu positions, no console errors.

Toggle as the eidos pilot: subdirectory layout (recipe + Svelte wrapper +
types + index + README) replacing the flat CSS-only form. Pattern is
documented in eidos/components/README.md and the toggle README.
Shared types live in eidos/lib/types.ts. First export is `Size` (8 values
xxs..xxl + full); components narrow with `Extract<Size, ...>` per the
per-component-subset doctrine. No `Eidos` prefix on types — module path
already conveys the layer.
API doctrine:
- soma stays compound (Toggle.Provider) for symmetry with multi-part
- eidos exports both default + Provider so single-part components
accept both `<Toggle>` (ergonomic) and `<Toggle.Provider>`
(compound-style consumers)
SoundChannel eager-init fixes the autoplay race: AudioContext is created
+ resumed synchronously on the first user gesture (capture-phase
listener registered in the constructor), avoiding the previous race
where the first emit() scheduled the resume in a microtask outside the
gesture window.
Demo page (web/routes/toggle/+page.svelte) restructured so the live
preview renders ALWAYS above the tablist — Sema-tab Play buttons can
fire on the real toggle. Motion preview amplifies scale ×8 visually
only; doctrinal values stay in the <dl>.
Conventions 7-13 added to src/docs/sema-implementation-guide.md
covering: directory structure, wrapper composition, no Eidos prefix,
soma compound vs eidos flat, iconOnly sr-only body, sound eager-init,
docs-preview amplification.
CLAUDE.md gets a session hand-off block listing where things stand and
next concrete steps (migrate switch/collapsible/dialog/drawer/popover/
toast/avatar; wire topbar sound mute to masterGain; rename theme
tokens to drop the success/warning/danger fallback aliases).
