## Probes

```
GET https://api.specref.org/bibrefs?refs=HTML,CSS21,RFC2119
GET https://api.specref.org/bibrefs?refs=NOTAREALREF999
```

## Observed

First probe → HTTP 200, `content-type: application/json; charset=utf-8`,
`cache-control: public, max-age=86400`, 1,387 bytes. `HTML` resolves to a full record
(`title: "HTML Standard"`, `publisher: "WHATWG"`, `status: "Living Standard"`, authors
list, `repository`). But `CSS21` resolves to **only** `{"aliasOf":"CSS2","id":"CSS21"}` —
none of `CSS2`'s own fields (`title`, `href`, `status`, etc.) are inlined into the `CSS21`
entry even though `CSS2` was requested separately in the same batch and does appear, fully
populated, under its own `CSS2` key in the same response. A client must resolve the
`aliasOf` chain itself by re-looking-up the returned key in the same (or another) response —
the API does not flatten aliases for you, even within one batch call.

Second probe (one clearly-invalid ref) → HTTP **200** (not 404), body **`{}`** — a
completely empty JSON object, with no `error` field, no `status` field, and no mention of
the requested-but-unresolved `NOTAREALREF999` key at all. A caller checking "did my ref
resolve?" must test for key presence in the response object, not for any success/failure
signal in the envelope, because an unknown ref is silently dropped rather than echoed back
as null or flagged.

The response is cached for 24 hours at the HTTP layer (`cache-control: public, max-age=
86400`) regardless of whether the batch fully resolved or came back empty — a client that
retries a mistyped ref expecting a fresh answer a minute later may instead receive the same
cached `{}` from an intermediate cache, not from specref.org re-evaluating anything.
Both responses were served by an Express app directly (`X-Powered-By: Express`,
`X-Robots-Tag: noindex`) rather than through any API gateway layer.

## Why this matters

This is a field-semantics/empty-vs-absent trap: batching several refs where some don't
exist silently shrinks the result set with zero error signal, and an alias is not resolved
for you even when the target is sitting right there in the same response under its own key.

How observed: 2026-10-05T09:31:19Z and 09:31:24Z, two curl GETs, anonymous.
