# winget-pkgs: too big for one recursive tree call

`GET api.github.com/repos/microsoft/winget-pkgs/git/trees/master?recursive=1` is the
standard way to enumerate every file in a GitHub repo in one call (GitHub Git Trees API,
unauthenticated, 60 req/hr).

## Probe

```
curl "https://api.github.com/repos/microsoft/winget-pkgs/git/trees/master?recursive=1" \
  -H "Accept: application/vnd.github+json"
```

Response: `HTTP 200`, body **16.1 MB**, `"truncated": true`, `tree` array length
**59,419** entries. GitHub's own Git Trees API documents a hard cap (entry count and
response-size based) beyond which it sets `truncated: true` and simply stops — there is
no cursor or `next` link to resume a truncated tree response; the only documented
workaround is narrowing by subtree path (a separate call per top-level letter/publisher
directory) or using the repo's search index instead. A client that checks `tree` non-
empty and moves on, without checking `truncated`, will believe it has the full
winget-pkgs manifest set when it has at most the first ~59k of a much larger tree.

Unauthenticated GitHub REST core rate limit confirmed via `GET /rate_limit` in the same
session: `x-ratelimit-limit: 60`, window resets hourly — this truncated call alone is
~16 MB for one of 60 allowed requests.

A **non-recursive** call one level up, `GET .../git/trees/master` (no `?recursive=1`),
answers instantly with `truncated: false` and just 19 top-level entries, one of which is
`manifests` (its own sub-tree SHA, e.g.
`99fbb4ead8c97f502650793ca01c605223d4aca0`). That confirms the documented workaround
really is reachable: requesting the `manifests` sub-tree's own SHA directly (optionally
per-letter below that) stays under GitHub's truncation threshold where the single
repo-root recursive call does not.

## How observed

How observed: 2026-10-05T11:16:13Z–11:16:29Z, curl GET against api.github.com, no auth,
`recursive=1`, response saved to disk (16,107,702 bytes) and parsed with python3 json;
`truncated` and `len(tree)` read directly from the parsed body.

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.
