Per the doctrine update in GUIA §13: eidos for multi-part components
exposes BOTH a flat default that auto-composes Provider/Trigger/Content
AND the compound parts for advanced cases. Soma + morfo remain the
universal composable foundation underneath.
Why: with the previous "compound only" rule for multi-part, eidos
collapsible was a pure pass-through that added nothing operational —
the consumer wrote the same import + same shape as soma. The flat
default makes eidos earn its layer by collapsing the 90% case to a
single call:
// 90% case — flat ergonomic
<Collapsible bind:open>
{#snippet trigger()}Show details{/snippet}
<p>Body content.</p>
</Collapsible>
// Advanced — compound (parts in different subtrees, multi-trigger,
// conditional content)
<header><Collapsible.Provider bind:open>
<Collapsible.Trigger>Show</Collapsible.Trigger>
</Collapsible.Provider></header>
<aside>
<Collapsible.Content>...</Collapsible.Content>
</aside>
The architectural virtue: if the flat doesn't fit, a developer drops
to soma + morfo and composes freely. No vendor lock-in in the visual
layer; eidos is the design system convention, soma is the universal
primitive.
Files:
- src/uix/eidos/components/collapsible/collapsible.svelte (NEW): flat
default that auto-composes Provider + Trigger + Content via a
`trigger` snippet for the toggle label and `children` for the body.
- src/uix/eidos/components/collapsible/types.ts: adds
`CollapsibleFlatProps = SomaCollapsibleProps & { trigger?: Snippet }`.
- src/uix/eidos/components/collapsible/index.ts: exports `default`
(flat) plus named `Provider`/`Trigger`/`Content` (compound).
- src/uix/eidos/components/collapsible/{trigger,content,provider}.svelte:
fixed children destructuring so snippets propagate cleanly to soma
(was previously spreading $props() blindly which can lose snippet
bindings in Svelte 5).
- src/docs/GUIA_IMPLEMENTACION_SEMAUIX.md: NEW §13 "Doctrina del API:
soma compound, eidos opinionado" formalises the two-shape rule and
the architectural virtue (soma+morfo as universal foundation).
Renumbered §13/§14 → §14/§15.
- web/routes/collapsible/+page.svelte: live preview now uses the flat
form; eidos snippet shows the flat shape; soma snippet keeps the
compound shape; Notes tab updated.
- src/uix/eidos/components/collapsible/README.md: rewrote API section
with both shapes + the "if neither fits, use soma+morfo" escape.
Tests 218/218 green. npm run check baseline 39.

The collapsible demo only rendered the eidos snippet, which made the
"compound shape is the same" doctrinal point invisible: a reader
couldn't see that soma and eidos expose the same multi-part API,
differing only in import path and what each layer guarantees.
Now both code blocks stack in the Live tab:
- soma: includes the `<script>` boilerplate (`let open = $state(false)`)
to make the headless/structural-only nature explicit
- eidos: same shape, different import, no setup boilerplate (consumer
binds open directly with `onOpenChange={handleChange}` for the demo
trace)
Per doctrine §10, only single-part components (toggle/switch) get a
flat default export — multi-part keeps compound on both layers, so the
two snippets share shape. That's correct. The DIFFERENCE is the import
path, the visible boilerplate, and what each layer adds (soma:
structural contract; eidos: same surface + recipe CSS).

Two real bugs reported on the collapsible demo:
1. **Dark mode broken across all migrated components.**
- The docs site layout sets `document.documentElement.dataset.theme =
'light'|'dark'` — those are the selector names the docs CSS uses.
- The eidos themes (themes/base/{light,dark}.css) only respond to
`[data-theme='base-light'|'base-dark']`. Different namespace.
- Result: docs grays swap in dark mode but eidos doctrinal palette
(primary/secondary/neutral/affirm/fulfill/risk/threat/loss) stays
in light values, so component text renders dark on dark.
- Fix: each eidos theme now accepts BOTH selectors. `[data-theme=
'base-light'], [data-theme='light'], :root { ... }` and equivalent
for dark. Existing consumers that use `base-*` keep working; the
short `light/dark` aliases handle the docs site convention.
2. **Collapsible trigger jumps from center to left when expanded.**
- The preview-stage uses `display: flex; justify-content: center;
align-items: center;` — natural for buttons/switches that don't
grow.
- `Collapsible.Provider` is `display: block` so it shrink-fits its
content as a flex item. Closed = trigger-width (centered visually);
open = trigger + content width (longer, so the visual center
anchors trigger at the left edge).
- Fix: collapsible demo overrides the preview-stage style with
`justify-content: flex-start; align-items: flex-start` and wraps
the provider in a `max-inline-size: 32rem` panel. Disclosure
ergonomics need anchor-left + grow-down, not center.
- Also swapped the body's `--gray-50` (docs site token) for
`--color-surface-raised` + `--color-content-primary` (eidos
doctrinal tokens) so the panel inherits the dark-mode swap.
npm run check holds at the 39-error baseline.

Third component migrated to the eidos wrapper subdirectory pattern,
following the new "check air baseline first" discipline.
Air baseline recovered from commit 0a391408^:
- air/components/collapsible: 3 wrappers (Provider/Trigger/Content)
with `class` passthrough, `bind:open`, `onOpenChange`, manual
`air.interaction.play('expansion', enter|exit)` perceptual emit.
- No size, intent, color, or chevron slot.
Migration decisions (presented BEFORE coding per scope-approval rule):
- Two doctrinal events (`expand` + `collapse`, both emerge family,
sequence='pre', no intent — emerge is transitional). Replaces air's
manual `air.interaction.play` with `runtime.trigger('expand'|
'collapse')` which atravieses visual + sound + vibra channels.
- No intent/color/size — air didn't have them and disclosure is
non-evaluative per guide §3.1.
- Multi-part API: Provider + Trigger + Content (no flat default per
doctrine §10).
Files:
- src/uix/morfo/components/collapsible.ts: scope expanded to ['soma',
'sema'], events array added with two emerge events.
- src/uix/soma/components/collapsible/collapsible-provider.svelte.ts:
runtime.events handlers `expand`/`collapse` mutate state; toggle()
fires runtime.trigger(next ? 'expand' : 'collapse').
- src/uix/eidos/components/collapsible/{collapsible.css,
collapsible-provider.svelte, collapsible-trigger.svelte,
collapsible-content.svelte, types.ts, index.ts, README.md}.
- src/uix/eidos/components/collapsible.css (legacy flat) deleted.
- src/uix/eidos/index.css: import path updated to subdirectory.
- web/routes/collapsible/+page.svelte: full interactive testbed with
tabs (Live, Soma, Morfo, Sema, Eidos, Notes) mirroring switch's
structure. Sema tab shows per-channel signature cards for both
expand and collapse events.
Disciplina formalizada en CLAUDE.md hand-off + memory entry: "Check
air baseline first" before any future eidos migration. Switch shipped
without this check and lost ResponsiveProp<Size> (regression). Don't
repeat with collapsible/dialog/drawer/popover/toast/avatar.
npm run check holds at the 39-error baseline. Tests 218/218 green.
