examples/routstr_probe.rs subscribes to the docs-cited default relays
(damus.io, nostr.band, nos.lol) for kind-38421 provider announcements
plus a #d=routstr-provider fallback filter in case the kind number
drifted, then issues at most two unauthenticated GETs against any
discovered endpoint. Spends nothing: no Cashu token is ever built or
sent, no Authorization header, no Nostr event published, ephemeral
subscription key.
Reproduces (does not import) nostr_discovery.rs::build_nostr_client's
Tor-proxy-aware client shape, since this package ships no [lib]
target and an examples/ binary cannot reach binary-crate internals.
Live run against the three default relays (60s total wait budget)
found zero matching events under either filter — recorded honestly
as NO LIVE PROVIDER OBSERVED, exit 0, per the plan's "no provider
found is a first-class outcome" requirement. Full output feeds
13-ROUTSTR-FINDINGS.md in the next commit.
