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.

Strings move into Localization/Strings.resx plus a Russian satellite. XAML uses
a {l:Loc Key} markup extension that yields a binding through the localizer's
indexer rather than a resolved string, so changing the language raises
PropertyChanged for the indexer and every caption in the app re-reads at once.
Resolving strings once at load would have been simpler and would have needed an
app restart to take effect.
Three places where this is more than a string swap:
Russian has three plural forms, so counted messages are assembled from .One /
.Few / .Many keys via Localizer.Plural instead of "{0} records" with an English
plural glued on. "1 запись", "3 записи", "7 записей".
Enum captions in pickers go through LocalizedOption<T>. A value converter would
resolve the caption once and never notice a language change; the wrapper keeps
identity on the enum value so the selection survives, while the label follows
the localizer. It needed a non-generic base for DataTemplate x:DataType, since
Avalonia 12 compiles bindings by default and cannot infer one for an open
generic.
Text originating in the domain would otherwise have stayed English under a
Russian UI — the screenshots showed exactly that. AvParser.Core still knows
nothing about languages: ParseError now carries a Code and Arguments, and the UI
translates Parse.Error.{Code} with a fallback to the English message. Parser
names work the same way (Parser.{id}.Name falling back to DisplayName), which
keeps "add a parser = one registration line" true — an untranslated parser shows
its own name rather than a missing-key marker.
Both .resx files are generated from one table so a key cannot exist in one and
be missing from the other, and the tests assert that, plus no blank translations
and identical {0} placeholder sets — a translation that drops a placeholder
throws at runtime rather than merely reading oddly. A headless test switches
language on a live shell and asserts the rendered text changes without the tree
being rebuilt.

The parser will need to move between proxies, so this adds the module it will
sit on: pluggable sources, a pool that hands proxies out and learns from the
outcome, three rotation strategies, and a page to drive it.
Sources are IProxySource implementations. The public proxifly/free-proxy-list
feed is fetched as the combined all/data.json through jsDelivr and filtered
locally — one conditional request beats four per-protocol ones that can disagree
mid-publish — and cached for the five minutes upstream takes to regenerate. A
feed that is down keeps serving its last payload rather than emptying the pool.
The user's own list lives in proxies.custom.json beside the settings, takes a
pasted blob, and names the lines it could not parse instead of quietly dropping
them.
Both knobs the pool exposes are settings, as asked: rotation is Sticky (default,
the only one that keeps site sessions coherent), RoundRobin or WeightedRandom;
liveness is either a parallel sweep of the whole pool or a probe at hand-out
time. Free lists are a few percent alive, so skipping verification entirely
means mostly waiting on timeouts.
Two invariants worth keeping, both of which cost a bug to find:
Availability is decided by the quarantine, never by Health. Excluding everything
that has ever failed made the quarantine window dead code and discarded proxies
permanently on their first hiccup, which is exactly wrong for addresses that
flap constantly. Health only orders the candidates now.
A probe verdict does not touch the success/failure counters. Those are about
real requests, and letting a sweep over a few thousand proxies rewrite them
would drown the evidence weighted selection reads.
SOCKS needs no extra package — .NET resolves socks4/socks4a/socks5 in WebProxy —
but a proxifly record with "protocol": "https" is still an HTTP proxy reached
over http:// with CONNECT, not an https:// scheme.
115 new tests. Also fixes a pre-existing flake: a command gated on another
command's IsExecuting cannot be driven straight after its Execute() completes,
because IsExecuting is published on the output scheduler.
