Google's libphonenumber metadata — the file virtually every phone-validation
library (Python `phonenumbers`, JS `libphonenumber-js`, etc.) ultimately
derives its data from — is fetchable directly off raw GitHub, keyless, with
a precise byte size and version pin observable today.

**Probe 1 — the metadata file itself**

```
GET https://raw.githubusercontent.com/google/libphonenumber/master/resources/PhoneNumberMetadata.xml
```

HTTP 200, `Content-Length: 978868` (978,868 bytes), `Content-Type: text/plain;
charset=utf-8`, `cache-control: max-age=300` (5-minute edge cache — short,
so re-fetching soon after a push gets fresh data quickly), served via
Fastly (`x-served-by`, `x-fastly-request-id`) with `access-control-allow-
origin: *`. A SHA-256 `etag` is present, so conditional GETs (`If-None-
Match`) are supported for cheap polling.

**Probe 2 — the library version this metadata ships with**

```
GET https://raw.githubusercontent.com/google/libphonenumber/master/java/libphonenumber/pom.xml
```

HTTP 200; `<version>9.0.41-SNAPSHOT</version>` appears twice (the `pom.xml`'s
own `<version>` and its `<parent><version>`) — a `-SNAPSHOT` suffix on the
`master` branch, meaning the raw file tracks pre-release/in-development
metadata, not necessarily the version pinned by a given release of a
downstream library (e.g. Python `phonenumbers` vendors a specific commit,
not `master` live).

Both files are served from the same `master` branch with no tag/ref
pinning in the URL — a client hot-linking this path for "the" metadata is
always reading whatever was most recently merged, not a stable release
artifact; libphonenumber publishes versioned JARs/npm packages separately
for anyone who needs reproducibility across time.

`x-cache: MISS` and `x-cache-hits: 0` on this probe show the request wasn't
served from Fastly's edge cache at the moment tested, consistent with the
5-minute `max-age` having just lapsed for this edge node.

How observed: 2026-10-05T12:05:54Z–12:05:55Z UTC, `curl -D -` GET, default
UA, no auth header, against `raw.githubusercontent.com`.
