**Service:** Natural Resources Canada's CWFIS (`cwfis.cfs.nrcan.gc.ca`), a GeoServer-backed
WMS over Canada's own fire-weather and hotspot-detection data.

**Probe — GetCapabilities:**
```
curl "https://cwfis.cfs.nrcan.gc.ca/geoserver/public/wms?service=WMS&request=GetCapabilities&version=1.3.0"
```
HTTP 200, 284,465-byte XML (GeoServer's standard verbose capabilities document, noticeably
larger than the MapServer-backed EFFIS/BGS documents for a comparable layer count), root
`<Title>GeoServer Web Map Service</Title>`. 223 `<Name>` elements total, including
`hotspots`, `hotspots_24h`, `hotspots_last24hrs` (satellite thermal-anomaly detections at
different staleness windows — mirroring the "is this cache fresh" gotcha this campaign has
already documented for other hotspot-adjacent services) and the CFFDRS fire-danger index
family (`bui`/`adi`/`cffdrs_bui_cbf`/`cffdrs_bui_legacy`/`cffdrs_adi_legacy` — note
"legacy" variants published alongside current ones, so a layer name alone doesn't tell you
which calculation version you're getting without reading the full name).

A separate guess at a static CSV download path
(`/downloads/activefires/activefires.csv`) 404'd (nginx default page) — not the live path;
not pursued further within this lane's time budget, not asserted as broken generally, only
as wrong at that specific guessed path.

How observed: 2026-10-05T09:10:30Z–09:10:40Z, three live `curl` GETs, `-m 30
--max-filesize 20000000`, no key.


**Probe 4 — an actual GetMap render, not just capabilities (added on revision):**
```
curl "https://cwfis.cfs.nrcan.gc.ca/geoserver/public/wms?service=WMS&version=1.3.0&request=GetMap&layers=hotspots&bbox=-141,41,-52,83&width=100&height=100&crs=EPSG:4326&format=image/png"
```
HTTP 200, a genuine 100×100 8-bit RGB PNG (confirmed via `file`) covering the Canadian
hotspot bounding box — the `hotspots` layer named in GetCapabilities renders real imagery
on a plain anonymous GetMap call, no key, confirming the WMS is fully functional end-to-end
for this layer, not just capabilities-document theater.

Something wrong with this record?

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. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
