Probe (2026-10-05T11:17:4xZ), pursuit.purescript.org (PureScript's
package/docs search and the closest thing it has to a registry API).

1. `GET /search?q=Effect` with no `Accept` header -> 200,
`content-type: text/html; charset=utf-8` — a full rendered
search-results page meant for a browser.

2. The **identical URL**, `GET /search?q=Effect` with
`Accept: application/json` -> also 200, but `content-type` switches to
`application/json; charset=utf-8` and the body is an array of result
objects mixing package and module hits:
`{"info":{"deprecated":false,"type":"package"},"markup":"\n",
"package":"purescript-effect","text":"","url":
"https://pursuit.purescript.org/packages/purescript-effect",
"version":"4.0.0"}` for the package hit, and a second entry
`{"info":{"module":"Effect","type":"module"},"markup":"<p>This module
provides the <code>Effect</code> type...","package":"purescript-effect",
...}` for the module-doc hit. No redirect, no distinct path — the
`Accept` header alone decides the representation, silently, with the
same 200 status either way; a client that forgets the header gets a
whole HTML document back with no error to signal the mismatch.

3. `GET /packages/purescript-prelude/latest` with
`Accept: application/json` -> 404, body `{"message":"Not Found"}` — this
plausible npm/PyPI-style "latest" convenience path does not exist on
Pursuit at all.

4. `GET /packages/purescript-prelude` (no `/latest` suffix), same
`Accept` header -> 303 (See Other) — the canonical path is a redirect to
a specific versioned page, not a stable JSON resource; a client wanting
machine-readable package data must follow the redirect by hand rather
than rely on a version-less convenience path.

How observed: 2026-10-05T11:17:4xZ, four GETs via curl with/without
`-H "Accept: application/json"` (`--max-filesize 20000000 -m 20`),
outputs in `/private/tmp/nh-b34c/bodies/pursuit_search.json`,
`pursuit_pkg.json` (404 body), status of `pursuit_pkg2.json` (303)
confirmed via `-w "HTTP:%{http_code}"`; content-type confirmed in
`pursuit_headers.txt`.
