- Updated `IMediaSourceCatalog` to support user-added media sources, allowing dynamic editing and management of sources.
- Removed the `UrlListSource` class as its functionality is now integrated into the new catalog structure.
- Enhanced `CollectOptions` to default `RequireProxy` to true, ensuring stricter handling of proxy requirements.
- Improved error handling in `ParseError` to include a `Subject` field for better context on failures.
- Adjusted dependency injection to reflect changes in media source management, removing old source registrations.
- Introduced background proxy checks to ensure a more robust proxy pool management during collection processes.
These changes streamline the media collection process and improve the overall user experience by providing clearer error reporting and more flexible source management.
The scaffolding domain existed to prove the shell end to end before there was
anything real to put in it. There is now, so it goes - as CLAUDE.md promised it
would.
Gone: the two sample parsers, ITextParser, ParsedRecord, the parser catalog,
ParseViewModel and ParseView, their tests, and the settings key that remembered
which parser was last used. ParseError.LineNumber becomes Index, since for a
listing "line 42" was simply untrue, and the error keys move from Parse.Error.*
to Collect.Error.* now that parsing is not a concept here.
Kept: IParser<,>, ParseOutcome, ParseProgress and ParseError. The streaming
contract was always the general part - it was only ever the text-shaped closure
of it that was scaffolding.
Rendering the dashboard caught two keys that were referenced but never added
during the rename: the XAML was repointed and the resources were not. The parity
test could not see it, because it compares the two files against each other and
a key absent from both is consistent. That gap now has its own test, which reads
every {l:Loc} in the XAML and checks it resolves - a screenshot is too late and
too manual a way to find a missing string.

Third step: the collector becomes wireable. Both catalogs coexist for exactly
this one step, so ParseViewModel and every existing test stay green while the
new domain is proven.
IMediaSource reuses the closed-generic trick ITextParser used, and for the same
reason - the container cannot resolve an open generic as IEnumerable<T>, so
adding a source stays a one-line registration. Its input is a MediaQuery rather
than text, because a source that walks a paginated listing needs an endpoint and
a cursor, not a string.
Sources discover; they do not download. That split is why UrlListSource lives in
the domain with no network at all, and why everything hard about fetching lives
in one place instead of once per source.
The catalog takes an explicit default id. Left to alphabetical order the landing
source would be the network one, so the app would open behind the proxy gate
before the user had asked for anything.
The runner decouples discovery from downloading with a bounded channel - a
listing of two hundred thousand items must not materialise because the workers
are slower than the source - and owns its workers, waiting for them even when
cancelled. Without that a stopped run keeps writing to the store after the page
has said it stopped.
The own-service listing is read leniently: the service on the other end is the
user's own and should not have to be rewritten to match a schema we invented, so
both a bare array of addresses and an object with items and a cursor work.

Greenfield skeleton for a parser desktop app. The domain is deliberately a
placeholder — IParser<TIn,TOut> plus two sample parsers — so the shell is
runnable and verifiable end to end before real logic lands.
Layers run one way: Core (no Avalonia, no IO) <- Infrastructure <- UI <- Desktop.
UI is a class library rather than the exe so headless tests build real views
without dragging in Program.cs, Serilog or the container.
Adaptive layout is built from what Avalonia actually offers, since it has no
AdaptiveTrigger or media queries: ResponsiveLayout observes Visual.Bounds and
projects a breakpoint onto both an attached property and :compact/:medium/
:expanded pseudoclasses, with 24px hysteresis so dragging a window edge cannot
make the layout flap. Pane state lives in the view model because a style setter
loses to a local value permanently; styles own only the visual variance.
Stack notes worth remembering: Avalonia.ReactiveUI is deprecated in favour of
ReactiveUI.Avalonia, and ReactiveUI 24 runs on the Primitives engine (RxVoid,
ISequencer, Signal<T>) and no longer self-initialises. Avalonia.Headless.XUnit
12.x requires xUnit v3. InvariantGlobalization must stay false or Semi.Avalonia
throws in its static constructor.
102 tests across three projects, including headless guards for the two failures
that are otherwise completely silent: a stylesheet whose selectors match nothing,
and a light palette too low-contrast for cards to read.
