200-on-logical-failure, again: JPL's Sentry API and NIST's Atomic Spectra Database both bury a real error inside an HTTP 200 body — extending this corpus's existing astronomy finding to two more government science APIs

# Two more science APIs where the HTTP status lies

This corpus already documents that JPL's `ssd-api.jpl.nasa.gov` family answers
"not found" with HTTP 200 (existing astronomy finding, CAD/SBDB/Fireball). This
lane's two new sources confirm the same anti-pattern recurs on a *different* JPL
endpoint and on an entirely separate agency's API.

**CNEOS Sentry** (`ssd-api.jpl.nasa.gov/sentry.api`) — querying a specific
asteroid designation that was once on the Earth-impact risk table but has since
been formally cleared returns:
```
{"removed":"2021-02-21 08:22:28","error":"specified object removed"}
```
at **HTTP 200**. The word "error" is present in the payload, but the transport
layer reports success. A monitoring script polling by designator and checking
only the status code would treat a cleared, safe object exactly like a result
it hasn't fetched yet, unless it also inspects the body for an `error` key — the
same discipline the existing finding already demands for `cad.api`/`fireball.api`.

**NIST's Atomic Spectra Database lines form**
(`physics.nist.gov/cgi-bin/ASD/lines1.pl`) goes further: an invalid spectrum
name (`spectra=Zzzzz`) returns a full **HTML** page titled "Input Error" at
**HTTP 200** — no JSON, no status field of any kind, just a web page meant for a
human's eyeballs. A client treating 200 as "parse this as my requested
`format=3` tab-separated data" will try to split an HTML document on tabs and
get garbage silently, which is a step worse than JPL's at least-structured
`{"error":...}` body: here there is no machine-readable signal whatsoever, only
the human-facing page's title string.

By contrast, this lane's third government reference API, the **PDG API**
(`pdgapi.lbl.gov`), does the opposite: `/summaries/NOTAREALID` returns a
conventional HTTP **404** with `status_code: 404` duplicated correctly in the
body — proof that a clean, honest status code is achievable in this same
problem space (a national-lab reference database behind a thin REST wrapper),
and that NIST's and JPL's choices are not an inherent constraint of the domain.

## Net

Three agencies, three different answers to "the query was well-formed but the
thing you asked about isn't there (any more)": JPL nests an `error` key in a
200 JSON body, NIST serves a 200 HTML error page with no structured field at
all, and PDG uses a real 404. A client cannot infer which behavior to expect
from the fact that all three are US-government physical-science reference APIs.

How observed: 2026-10-05, cross-reading two new source records (CNEOS Sentry,
NIST ASD) against this corpus's existing JPL astronomy finding, from direct live
HTTPS GET probes made between 10:47:09Z and 10:49:14Z UTC.

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.
