M4 of design/library-scanner-plugins-implementation-plan.md, plus WP6.2.
WP4.1 — SourceToggles and ProvidersCard merge into Library/Sources.tsx. They
were two cards because they were two different things: scanners were compiled
into the host, plugins were an afterthought. After the extraction they are the
same thing — the host reports ONE list of sources whose ids match whether they
came from a built-in scanner or the plugin replacing it — so one surface is both
simpler and the only honest presentation. Each row carries its toggle, a
running/stopped badge for plugin sources, an entry count, filter, settings and
an uninstall that offers to remove the games too. An "Add a source" rail lists
uncatalogued library plugins with a "Detected" badge; `detected` is deliberately
tri-state, so only a POSITIVE probe badges — an entry with no probes for this
platform is unknown, and calling that "not installed" would be a lie.
The settings drawer (SourceSettings.tsx) renders a generic form from the
plugin's own JSON Schema over GET/PUT /__config, through the existing
session-gated /plugin-ui/<id>/ proxy — zero new host surface, and the browser
never learns the plugin's port or secret. It flattens allOf branches (effect
nests a checked schema's annotations there, so a form reading only the top level
silently loses every title and default) and falls back to a JSON editor when any
field is a shape it cannot express — partial rendering would be worse than none,
because a field missing from the form is a setting the operator cannot change.
WP4.2 — uiPlugins() now excludes category "library", which covers both the
sidebar and the mobile overflow since they share the selector. The
/plugins/$pluginId/$ route still resolves, so existing deep links keep working;
library plugins are just not advertised.
WP4.3 — LibraryGrid groups role:"launcher" entries into a rail above the grid,
and the empty state points at the sources surface rather than leaving a bare
grid (after extraction, "no games" is the expected first-run state).
WP6.2 — a migration banner offering one install per still-built-in scanner whose
plugin is catalogued. One button per scanner, never a single "migrate
everything" and never a silent auto-install: installing code stays an explicit
operator act, and per-scanner is what makes it safe to repeat (the claim
suppresses the built-in idempotently, so a half-finished migration is a valid
state).
WP4.4 — i18n en+de (kept under the existing "Game sources" label rather than
minting a third "Plugins"), Storybook stories for the sources card in three
states, the launcher rail and the banner. Gates: orval regen, tsc clean, vite
build clean, check-i18n green at 595 messages for both locales.
Still owed: the browser click-through (the store's Tabs-theme bug shipped
through green types and lint), and an AppShell nav story — that one needs the
plugins query mocked, which does not exist in this Storybook setup yet.
