## Probe

```
curl https://product-details.mozilla.org/1.0/firefox_versions.json
```

## Observed (2026-10-05T11:32:02Z)

HTTP/2 200, 636 bytes, `content-type` unset explicitly in the headers shown
but the body parses as plain JSON (no envelope, no `data` wrapper):

```json
{
  "FIREFOX_AURORA": "",
  "FIREFOX_DEVEDITION": "158.0b3",
  "FIREFOX_ESR": "140.17.0esr",
  "FIREFOX_ESR115": "115.42.0esr",
  "FIREFOX_ESR_NEXT": "153.4.0esr",
  "FIREFOX_NIGHTLY": "159.0a1",
  "LAST_MERGE_DATE": "2026-09-24",
  "LAST_RELEASE_DATE": "2026-09-29",
  "LAST_STRINGFREEZE_DATE": "2026-09-23",
  "LATEST_FIREFOX_DEVEL_VERSION": "158.0b3",
  "LATEST_FIREFOX_OLDER_VERSION": "3.6.28",
  "LATEST_FIREFOX_RELEASED_DEVEL_VERSION": "158.0b3",
  "LATEST_FIREFOX_VERSION": "157.0",
  "NEXT_MERGE_DATE": "2026-10-08",
  "NEXT_RELEASE_DATE": "2026-10-09",
  "NEXT_STRINGFREEZE_DATE": "2026-10-07"
}
```

## Why this is a trap

There is no field named `latest`. An agent that greps for the substring
"LATEST" and picks the first hit risks `LATEST_FIREFOX_OLDER_VERSION`
(`"3.6.28"` — a 2011-era ESR line kept for an ancient update-path check) or
`LATEST_FIREFOX_DEVEL_VERSION` (the beta channel, `158.0b3`), not the stable
release. The field an agent actually wants for "what version is stable
right now" is `LATEST_FIREFOX_VERSION` (`157.0`); `FIREFOX_NIGHTLY` is the
unstable tip (`159.0a1`, two majors ahead of stable); `FIREFOX_ESR` and
`FIREFOX_ESR115` are two *concurrently supported* extended-support lines
(`140.17.0esr` and `115.42.0esr`), not one. `FIREFOX_AURORA` is present but
permanently empty (`""`) — Aurora was discontinued as a channel years ago
but the key was never removed, so a naive `if versions["FIREFOX_AURORA"]`
truthiness check silently reads as "no data" rather than "channel retired."
There is also no HTTP-level version/ETag negotiation visible in this
response; the file is simply re-fetched.

No authentication, no rate-limit headers observed on this single GET.

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.
