Probe (2026-10-05T11:1xZ), Microsoft's vcpkg C/C++ package
manager, which documents no HTTP API of any kind — only a git-backed
versions directory inside the main repo.

1. `GET https://raw.githubusercontent.com/microsoft/vcpkg/master/versions/baseline.json`
-> 200, 225,410 bytes. Body: `{"default": {"<port>": {"baseline":
"<version>", "port-version": N}, ...}}` for every port in the registry —
confirmed via `json.load()` to contain exactly **2,871** ports under
`"default"` — e.g. `"abseil": {"baseline": "20260107.1",
"port-version": 3}`, `"3fd": {"baseline": "2.6.3", "port-version": 5}`,
`"7zip": {"baseline": "26.3", "port-version": 0}`. This single flat file
is the whole catalog's current-version index; there is no equivalent
summary endpoint anywhere else.

2. `GET https://raw.githubusercontent.com/microsoft/vcpkg/master/versions/f-/fmt.json`
(the per-port version-history file, path-sharded by the port's first two
characters — `f-` for `fmt`, so a client must compute the shard
directory itself with no listing endpoint to discover it) -> 200. Body:
`{"versions": [{"git-tree": "<sha>", "version": "<semver>",
"port-version": N}, ...]}`, newest first: `fmt` 12.2.0 port-version 1
(`git-tree":"7ca0b8c0026883daf28a0db75f6b4964bae2979a"`), then 12.2.0
port-version 0, then 12.1.0, and so on back through the port's whole
history. `git-tree` is a git **tree object SHA**, not a tag or commit —
resolving a specific historical version of a port means fetching that
tree object directly (e.g. via the GitHub Trees API or a sparse
checkout), not `git checkout <tag>`.

No search, no pagination, no content negotiation, no auth, and no
rate-limit headers beyond whatever GitHub's general raw-content CDN
applies — the entire public interface to "is this port available, at
what version, with what history" is these two static JSON shapes, one
global 2,871-port index plus one per-port history file, both served as
plain git blobs with no registry server in front of them at all.

How observed: 2026-10-05, two GETs via curl
(`--max-filesize 20000000 -m 20`), outputs in
`/private/tmp/nh-b34c/bodies/vcpkg_baseline.json` (225,410 bytes, 2,871
ports via `len(json.load(...)['default'])`) and `vcpkg_fmt.json`.
