- 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 pool now warms up from what the previous run learned instead of starting
cold every launch. Startup probes the remembered proxies first, stops as soon
as ProxyMinimumLive of them answer, and writes the survivors to
proxies.state.json after the warm-up and again on shutdown. Only proxies that
ever answered are stored: the feed republishes a few thousand dead addresses
every five minutes, and "was dead an hour ago" says almost nothing.
Remembered state is a hint, not a verdict. A restored proxy sorts first in the
warm-up queue but is not counted live until it answers in this session -
otherwise a launch a week later would report live proxies it had never spoken
to, the warm-up would skip the very entries it exists to re-check, and the
parser gate would open on week-old evidence.
That gate is the other half: a parser declaring RequiresNetwork will not run
while the pool has nothing live. The Parse page disables the run button and
shows a banner that leads to the Proxies page. Parsers that work on pasted text
are never gated - they have nothing to route, and blocking them would make the
app useless whenever the public lists are down. Two new settings cover the
escape hatch and the target: "allow network parsers without a proxy" and how
many live proxies to find at startup.

The pool was empty until someone pressed Refresh, which also meant the parser
would have had nothing to work with. A ProxyPoolLoader now fills it once at
launch; startup does not await it, because blocking on a public list being
reachable would be the wrong trade, and it never throws. The proxy page joins
the same operation rather than starting a second download, so it reports the
outcome whether it is opened during the load or long after.
That change surfaced a worse bug underneath. The first run still loaded zero
entries with no error logged at all, which turned out to be the feed source
never being asked: options said UseFeed=False and Protocols=None. Neither is
reachable from the UI — both are default(T).
The cause is that AppSettings kept its defaults on property initialisers, and
the source-generated deserialiser does not run them. Reflection-based
deserialisation of "{}" keeps them; the generated context does not. So a
settings.json written before a setting existed came back with default(T) for it:
the proxy feed switched off, the protocol filter empty, the probe timeout zero
and the probe URL blank — and the app looked like the network had failed.
Defaults now live on primary constructor parameters, which STJ applies for
absent JSON members on both paths, so an older file upgrades cleanly. The
regression test writes a settings file from before the proxy settings existed
and asserts each one comes back at its default. ToProxyOptions also treats an
empty protocol filter as "all", since a hand-edited file that matches nothing is
the least useful possible reading of it.
Also quietens IHttpClientFactory to Warning: four Information lines per request
buried everything the app said, and a proxy sweep makes thousands of them.
