First half of replacing the stub text domain with a media collector. Nothing
references this yet - the store is standalone and fully tested before anything
depends on it.
Blobs are addressed by SHA-256 and sharded two levels deep, so the same picture
re-uploaded at a dozen addresses costs one file. Downloads stage in a sibling
temp directory on the same volume and are promoted by rename, which is what
keeps blobs/ free of truncated files: a crash leaves a stray .part that the next
startup sweeps, never a half-image indistinguishable from a real one.
The SQLite index holds provenance separately from content, so purging one source
leaves blobs another source still references - that is what ref_count buys, and
it is recomputed rather than incremented because the item upsert can replace a
row pointing at a different blob. The seen_url journal deliberately outlives a
purge: without that, the next run downloads again exactly what the user just
deleted. Terminal outcomes are split from retryable ones so a flaky network does
not permanently lose content.
The showcase gives every item a dated, named path via hard links - a second name
for one file, not a second file. Hard links are a filesystem privilege rather
than a guarantee, so it degrades to copying and records which it achieved; the
UI has to be able to admit that. Names suggested by the origin are treated as
hostile: only the last path segment survives, Windows device names are pushed
aside, and the extension comes from the sniffed kind, never from the remote.

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.

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.
