The Driver's ask: one folder per BUNDLE with its ELEMENTS inside, bundles sorted by capability, highest
first. The rail listed every element flat under its own capability, so a bundle's elements were
scattered (gospel-resources' five screens sat in three sections). Now each capability section (5 → 1)
holds the bundles whose HIGHEST capability it is, in name order; a bundle with several elements is one
folder (country-posters, gospel-resources, my-upg-100-list, regions-dashboard, cities-internet), and a
single-element bundle is shown as its element. Composites keep their folded composition trees.
StudioTree identifies a plugin's row by a `canonical` flag rather than "depth 0", so auto-reveal opens
the bundle folder above an element chosen by URL or restored tab. New folder icon; 'elementsCount' and
'elements' in all 11 studio catalogues.
check:studio-rail (headless, gates:post) runs the studio's real rail code on the built manifest and
asserts the layout and one canonical node per plugin (21 bundles, 33 elements); it fails on the previous
rail. Also: poster.json:dpi is declared identical on purpose in check:i18n-never-translated (a unit
symbol kept as-is by project decision), which had turned that gate red on main.
rega's :dir(rtl) mirror for VerticalTabsLayout (5e7f73d0) compiled into
the studio, but nothing set the direction, so the studio stayed
left-to-right in Arabic. The studio now sets dir from the language
list's own dir flag, as doxa-maps-spa does.
The Explorer tree's own CSS assumed left-to-right: indentation, indent
guides, the active-row bar, the part count and the slim-rail activity
icons used left/right properties. They now use logical properties
(padding-inline, inset-inline-start, border-inline-start,
margin-inline-start), so they mirror, and a closed twisty points toward
the start of the line.
Checked at 1280x900: in Arabic the rail sits on the right, the active
bar on its right edge, the guides on the right, and doxa-simple-map
still renders its map; in English the geometry is unchanged (rail 0..256,
stage from 268).
Choosing a language in the studio translated the plugins it mounts but
left the studio itself in English: the title, the count, the filter box,
Collapse all, the section names, Copy embed, the loading and error
messages, and the rail's own Collapse button and aria labels.
The studio's strings now live in library/i18n/locales/<lc>/studio.json
for all 11 locales, held to key parity by check:i18n-parity like every
other catalog. The studio has no vue-i18n instance, so it looks strings
up directly (locale, then English, per key). The Explorer tree takes
them through a `strings` prop. VerticalTabsLayout gains an optional
`labels` prop for its five words; hosts that do not pass it keep the
English defaults, so doxa-maps-spa is unchanged until it opts in.
Verified by switching the studio through every language its switcher
offers (en, es, fr, pt, ar, ru): no English left in the studio chrome.
Technical names (CAP n, element tags, tier machine names in tooltips)
stay as they are.
The studio's rail was hand-rolled vertical tabs stretched into a tree.
It is now an Explorer tree modelled on the VS Code Explorer, keyboarded
per the WAI-ARIA tree pattern:
- CAP 5 -> CAP 1 sections with sticky headers; one-line rows with the
name and a muted element tag; twisty on the left; indent guides.
- Composites fold; their parts hang beneath, one level at a time, each
part opening the plugin's one canonical entry.
- A filter box on top shows matches together with the path to them.
- One view action, Collapse all.
- Auto-reveal: opening a plugin by click, URL hash or remembered tab
scrolls its row into view and opens its section.
- Arrow keys walk the tree, Right/Left open, close and move between
parent and child, Enter opens, a letter jumps to the next name.
- The slim rail becomes an activity bar with one icon per section.
- Fold state is remembered per page.
The tree lives in plugin-designs/plugin-studio/src/StudioTree.vue and
fills VerticalTabsLayout's new #rail slot, so the layout still owns the
collapse toggle, mobile drawer and slim strip. The alias, depth and
branch row fields added to the layout earlier today are removed again:
nothing else used them.
The studio host now has a default height (85vh, min 480px), as
doxa-maps-spa does. Pasting the published embed snippet into a plain
page mounted a complete studio 0px tall. A page's own height or
--plugin-studio-height still wins.
The studio gates that click tabs by text now also match tree rows.
Rebuilt the plugin-studio bundle and re-baked its SRI.
