an exclusionary rule, made structural. a plugin does not render a screen: it
contributes panels and says how they are arranged, and the shell renders
WorkspaceView around them.
web/panels.ts appRegistryMetas — at least one panel
web/layout.ts defaultLayout — how they are arranged
both required the moment web/ exists, and missing either is refused at discovery
by name and with the reason. tested:
probeplug: has a web/ directory but is missing web/layout.ts.
Every plugin route renders a Workspace: contribute panels and a layout,
not a screen.
there is deliberately no way to export a component. one that could would be free
to render a bare div, a full-page form, or its own navigation, and the platform
would become a shell hosting strangers' layouts rather than one application.
non-compliance is not so much refused as unrepresentable — there is nowhere to
put a screen.
the shell registers <prefix> and <prefix>/:section, exactly as the core screens
do, so a plugin's sections stay addressable and cmd-clickable, and panels read
useParams independently rather than passing state between themselves.
appTypes.allowed is pinned to that plugin's own keys, so a persisted layout
naming something else falls back instead of rendering another plugin's panel
inside this screen.
the example plugin is rebuilt to model it — two panels, a layout, one of them
calling its own /api/example/ping through useClient — because the reference
implementation is what everyone copies.

the last piece. installing a plugin now brings its UI with it.
a bundler cannot follow import(runtimeString), so which plugins have a frontend
cannot be answered from the database at render time — it has to be written into
source first. Plugins.gen.tsx is that file: concrete imports, generated from
what is installed, gitignored because it describes THIS machine.
App.tsx keeps its core routes and gains one map. the wildcard hands the whole
subtree to the plugin's own router, which react-router nests natively.
serving moved to build/ in production. the html import is bundled once when the
module graph loads and can never change after, which is precisely why a plugin's
frontend needed a restart; Bun.build measures ~900ms for a 25MB bundle, so an
install can just rebuild. development keeps the html import, because that is
what gives HMR and bun --watch restarts on every source change anyway.
verified end to end against a running server, no restart at any point: install
regenerated the module, rebuilt the bundle (chunk hash changed), and the
plugin's own markup was in it; /example and /example/deeper both served; disable
took it back out of both the module and the bundle and 404'd the api; enable put
it back.
three things worth recording because they were found rather than reasoned:
the shell output is named after the ENTRYPOINT — index.gen.html, not index.html
— and naming: { entry: '[name].[ext]' } does not change it because [name] is
'index.gen'. found as a 503 on the first boot after the switch.
App.tsx already destructured a `plugins`, from useServerSettings — the DEAD
plugin system that scans a directory which does not exist and always returns [].
it silently shadowed the import. the new one is `installedPlugins` and says why.
seedAppRegistry takes plugin panels as an argument rather than importing them:
officerdev is a dependency of the shell, so importing upward would invert that.
756 pass, same 10 pre-existing failures.
