Architectural correction. Morfo was importing Svelte runes, $adom, and
$uix/sema — all violations of "morfo is pure declarative DNA". The
runtime that interprets a CompiledMorfo lives where it executes: soma.
Move:
- src/uix/morfo/runtime.svelte.ts → src/uix/soma/runtime.svelte.ts
- src/uix/morfo/runtime.svelte.test.ts → src/uix/soma/runtime.svelte.test.ts
Rename (consistent with the move; "soma's runtime", per the doctrine
"morfo declares, soma executes"):
- class MorfoRuntime → SomaRuntime
- createMorfoRuntime() → createSomaRuntime()
- type MorfoRuntimeSources → SomaRuntimeSources
- error prefixes [morfo-runtime] → [soma-runtime]
Sema is now genuinely ornamental:
- ActiveUix.semantic returns EngineSemantic | undefined (no longer
throws when no engine is configured). Components in SSR / headless
tests / audio-disabled environments stay functional.
- SomaRuntime.trigger() skips the emit step AND the target-resolution
check when no engine is present — only requires a DOM target when
something will actually be emitted.
- Soma.semantic getter returns | undefined too (was non-optional).
Consumers updated:
- src/uix/active-uix/active-uix.svelte.ts — imports createSomaRuntime
from $soma; semantic getter returns | undefined
- src/uix/active-uix/types.ts — interface SomaRuntime, semantic | undefined
- 8 providers (toggle, switch, collapsible, dialog, drawer, popover,
toast, avatar) — type SomaRuntime, import path $soma
- src/uix/soma/index.ts — re-exports createSomaRuntime + types
- src/uix/morfo/index.ts — drops the runtime re-exports (morfo is pure)
- src/uix/sema/signal.ts — JSDoc reference updated
- src/uix/soma/core/soma.svelte.ts — semantic getter | undefined
Test added: SomaRuntime.trigger() succeeds without a semantic engine
(skips emit + target check, runs handler directly).
Docs aligned to the new shape:
- active_architecture.md — runtime locations, sema as ornamental
- soma/SOMA_ARCHITECTURE.md, soma/README.md — name + import paths
- morfo/README.md — file listing now flags morfo as PURE TS, points
at soma/runtime.svelte.ts for the interpreter
- sema/README.md — SomaRuntime references
- README.md — root architecture diagram
- CLAUDE.md — hand-off note
Tests 218/218 green. npm run check holds at the 39-error baseline.

Deleted 60 obsolete documents that no longer reflect the active-uix
state:
- 47 per-component audit logs (*-audit.md, audit_N.md, AUDIT.md)
- 5 global soma audits (AUDIT_1, codex_audit, soma-audit-04-20/21,
audit-prompt template)
- 5 closed studies (soma/study, morfo/study, morfo/DESIGN, morfo/
PROVIDER_STUDY_2026-04-23, uix/CONTINUITY_2026-04-24)
- 2 superseded refactor proposals (refactor_claude, refactor_code)
- 1 stale bug log (form/BUG-onchange-onblur-hang — repro path
src/routes/test/sium/kitchen-sink no longer exists)
Updated the remaining operational references to drop dead links and
reflect the post-cleanup architecture:
- src/uix/README.md — rewritten links section, dropped pointers to
terra/air/CONTINUITY/refactor docs, updated adom/dom paths
- src/uix/active_architecture.md — header now dated 2026-05-08, lists
the major shifts since 2026-04-26 (provider inheritance dropped,
eidos in production, doctrina parte IV, sound eager-init); pendings
section reflects the eidos migration roadmap; "see also" purged of
deleted files
- src/uix/morfo/README.md — file tree updated (removed DESIGN/study,
added compile/runtime/PERMUTATION_RUNNER); see-also pruned
- src/uix/sema/README.md — SoundChannel section now describes the
eager-init pattern (constructor-time, not lazy); pointer to
sema-implementation-guide added
- src/uix/soma/README.md — drops terra/air mentions, declares the
actual dependency direction (eidos -> soma, not the reverse)
- src/uix/soma/SOMA_ARCHITECTURE.md — §15 rewritten as "Estado actual
y deuda histórica" reflecting Provider-inheritance-drop; demo path
updated to web/routes/
- src/uix/soma/COMPONENT_GUIDE.md — A23 dates section now points to
$libs/days (no external/dates façade); demo paths swapped from
/test/soma/* to web/routes/
- src/uix/morfo/PERMUTATION_RUNNER.md — paths swapped to web/routes/
with a relocation note
- CLAUDE.md — Refactor Documents section replaced with Reference
Documents pointing to per-layer READMEs
npm run check holds at baseline (39 pre-existing errors, none new).

## Slider thumb misalignment
`SliderThumbProvider.thumbStyle` used `translate(50%, -50%)` for both LTR
and RTL. For LTR that pushed the thumb RIGHT by half its width from the
`left: X%` anchor — visible symptoms in the time-picker / time-range-picker
demos:
- thumb never reached `left: 0` (centre at value=0 was offset by
thumbWidth/2)
- thumb overshot the track on the right edge at value=max
- drag felt off by the same amount throughout
Fix: use `translate(-50%, -50%)` for LTR (thumb centre aligns with anchor)
and keep `translate(50%, -50%)` for RTL (anchor is `right: X%`, thumb must
shift right by half its width to centre-align). Matches the logic already
used by `SliderTickProvider` which chose `tx = isRtl ? '50%' : '-50%'`.
Browser probe confirms: value=0 now centres at 0%, value=30/59 at ~50.8%,
style attribute reports `translate(-50%, -50%)` in LTR.
## soma README documents morfo
Added §4b "Morfo — contrato declarativo cross-layer" covering: why morfo
exists (6-place drift without it), how providers consume it
(`createAttrs(morfo)` + `registerContract(morfo)`), the mandatory
`as const satisfies Morfo` authoring pattern for literal-typed inference,
the 3-layer validation pipeline (schema / assertContract / morfo-check),
and the boundary (what does NOT go in morfo — props, prose, langs, state
machines, visual recipes). Updated the §4 structure listing so
`attrs/create-attrs.ts` shows the new signature.

Naming coherence across the part layer: the root part's `kebab` field now
matches its `name: 'Provider'`. The `createAttrs` special case still emits
`data-{component}` (no suffix) for the provider part — the DOM contract is
unchanged, only the authoring name changes.
Affected:
- createAttrs special-case: 'root' → 'provider'
- 66 morfos: kebab 'root' → 'provider'
- 77 soma provider files: `attrs.root` → `attrs.provider`, constructor
part arg 'root' → 'provider'
- Docs: A2 rule rewritten, morfo/README, soma/README example updates
- Test / schema / morfo-check: updated for new kebab
Toolbar fix: remove `itemsVersion` counter and per-item `$effect` blocks
that called `notifyItemsChanged()`. The pattern was an A30 violation —
each item's $effect read `ref.current`/`disabled` and wrote back to the
provider, which cascaded through `firstTabStop` → per-item `props`
$derived → DOM reattach → effect re-run, triggering
`effect_update_depth_exceeded` on page load. `isTabStop` now uses
`untrack` around the DOM walk so per-item `props` derivations only
depend on `lastFocusedElement`.
Verification: 7/7 morfo tests, 65/65 smoke, 66/66 morfo-check, no effect
loops detected across any demo page.

Explains why soma wraps Svelte runes instead of using them directly:
compiler magic limitation, cross-class composition need, migration path.

soma — new headless component system replacing terra:
- Provider base class with opt-in context injection
- Reactive system (state, readableActive, writableActive)
- Attrs system (createAttrs, contracts, helpers)
- Props system (mergeProps with on-prefix detection, no hardcoded event list)
- DOM utils (consolidated core, focus/, env)
- Keyboard, events, CSS, ID, config modules
- Layers: scroll, observers, visually-hidden, arrow, portal, text-selection,
dismissal (merged escape+dismissible), presence, focus-scope
- Collapsible component as first soma validation
air components:
- Pagination, Editable, PinInput (air-native), RatingGroup (air-native),
Stepper, FileUpload wrappers over terra
- Terra defaultContent refactor for children snippet pattern
- Avatar, Meter, Progress, Separator migrated to air-native
- Reactive utilities extracted to $lib/util/reactive (shared)
- $soma and $reactive aliases added
Architecture:
- soma is independent: no imports from terra or $lib/util/reactive
- Terra exports deprecated for migrated components
- README fundacional documenting all design decisions
