NIFC WFIGS wildfire perimeters (ArcGIS FeatureServer): HTTP 200 with an EMBEDDED error object for both a wrong service name and a missing token — identical status either way; the real URL has to be found via the org's own item-search API

**Service:** The Wildland Fire Interagency Geospatial Services (WFIGS) group publishes
authoritative current fire perimeters via NIFC's ArcGIS Online organization as a hosted
FeatureServer — but the service name is not obviously guessable.

**Probe 1 — a plausible but wrong service name:**
```
curl "https://services3.arcgis.com/T4QMspbfLg3qTGWY/arcgis/rest/services/WFIGS_Interagency_Fire_Perimeters/FeatureServer/0?f=json"
```
HTTP **200** (status line says success), body: `{"error":{"code":499,"message":
"Token Required","messageCode":"GWM_0003","details":["Token Required"]}}`.

**Probe 2 — a different wrong org/service guess:**
```
curl "https://services9.arcgis.com/RHVPKKiFTONKtxq3/arcgis/rest/services/WFIGS_Interagency_Perimeters_Current/FeatureServer/0?f=json"
```
Also HTTP **200**, body: `{"error":{"code":400,"message":"Invalid URL","details":
["Invalid URL"]}}` — a DIFFERENT error code/message (400 "Invalid URL" vs. 499 "Token
Required") for a DIFFERENT kind of wrongness, but both wrapped in the same HTTP-200
envelope; the HTTP status line alone never distinguishes "needs auth" from "wrong path"
from "works".

**Probe 3 — finding the real URL via ArcGIS Online's own item-search API (read-only,
GET):**
```
curl "https://nifc.maps.arcgis.com/sharing/rest/search?q=WFIGS%20Current%20Interagency%20Fire%20Perimeters&f=json&num=3"
```
HTTP 200, 135 total matches; the top hit's `url` field gives the real, correctly-cased
service: `https://services3.arcgis.com/T4QMspbfLg3qTGWY/arcgis/rest/services/
WFIGS_Interagency_Perimeters_Current/FeatureServer` (note: `_Fire_Perimeters` in probe 1
vs. the real `_Perimeters_Current`).

**Probe 4 — the real layer, metadata and count:**
```
curl ".../WFIGS_Interagency_Perimeters_Current/FeatureServer/0?f=json"
curl ".../FeatureServer/0/query?where=1=1&returnCountOnly=true&f=json"
```
`maxRecordCount: 2000`; `{"count":108}` live perimeters today — well under the 2000-row
clamp, so no truncation was observed at the current fire-season count, but the limit is
published in the layer metadata for when counts rise.

How observed: 2026-10-05T09:09:50Z–09:10:25Z, six live `curl` GETs, `-m 30
--max-filesize 20000000`, no key.

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.
