MeteoAlarm: the pre-2024-migration 'legacy-atom' per-country feed path is still the live one; feed slugs are lowercase-only and there is no aggregate 'europe' feed

## MeteoAlarm (`feeds.meteoalarm.org`) — per-country CAP-in-Atom feeds

MeteoAlarm migrated its site in 2024 (meteoalarm.org is now a Phoenix/LiveView app);
the question is whether the old per-country "legacy-atom" feed path from before the
migration survived it.

### Probe 1 — the pre-migration path pattern still resolves

```
curl -I "https://feeds.meteoalarm.org/feeds/meteoalarm-legacy-atom-france"
```
→ `HTTP/1.1 200 OK`, `content-type: application/atom+xml; charset=utf-8`, 40,607 bytes.
Root element: `<feed xmlns="http://www.w3.org/2005/Atom"
xmlns:cap="urn:oasis:names:tc:emergency:cap:1.2">` — the "legacy" name is the current,
live feed, not a deprecated alias; there is no newer-named successor path discoverable
from the feeds-root HTML.

### Probe 2 — the slug is case-sensitive lowercase-only

```
curl -o /dev/null -w "%{http_code}\n" \
  "https://feeds.meteoalarm.org/feeds/meteoalarm-legacy-atom-FRANCE"   # → 404
curl -o /dev/null -w "%{http_code}\n" \
  "https://feeds.meteoalarm.org/feeds/meteoalarm-legacy-atom-france"   # → 200
```
Only the exact lowercase country-name slug resolves; the capitalized variant is a
clean 404, not a redirect or a case-insensitive match.

### Probe 3 — there is no aggregate "europe" feed any more

```
curl -o /dev/null -w "%{http_code}\n" \
  "https://feeds.meteoalarm.org/feeds/meteoalarm-legacy-atom-europe"   # → 404
curl -o /dev/null -w "%{http_code}\n" \
  "https://feeds.meteoalarm.org/feeds/meteoalarm-legacy-atom-germany"  # → 200
```
`germany` resolves exactly like `france`; `europe` (a continent-wide aggregate some
older integrations assumed existed) is a 404 — MeteoAlarm's "legacy" feeds are strictly
per-country, one feed per EU/EEA member/participant, no bundle.

### Content shape

The feed carries a `rel="hub"` link to `https://pubsubhubbub.appspot.com/`
(PubSubHubbub/WebSub, for push rather than polling), a `<rights>` element asserting
"Licensed under terms equivalent to CC BY 4.0, with additional requirements...", and a
`<generator>MeteoAlarm Producer Server</generator>` — the backend self-identifies as
the producer side of the pipeline, distinct from the 2024 consumer-facing
`meteoalarm.org` site.

How observed: 2026-10-05T08:46:21Z-08:46:37Z, curl against feeds.meteoalarm.org (no
auth, no User-Agent requirement observed).

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named.
