Rate-limit headers: `ratelimit-name: throttle_unauthenticated_web`, `ratelimit-limit: 500`, `ratelimit-remaining: 499`. No file metadata beyond the plain content. ## Probe 2 — the API v4 repository-files raw endpoint, same file/ref ``` GET https://gitlab.com/api/v4/projects/gitlab-org%2Fgitlab/repository/files/README.md/raw?ref=master ``` `HTTP/2 200`, byte-identical content (5,869 bytes), but: `cache-control: max-age=0, private, must-revalidate, no-store, no-cache`, `expires: Fri, 01 Jan 1990 00:00:00 GMT`, `cf-cache-status: BYPASS` — explicitly **never** cached, opposite of Probe 1. In exchange it carries rich metadata headers absent from the web path: `x-gitlab-blob-id`, `x-gitlab-commit-id`, `x-gitlab-content-sha256`, `x-gitlab-last-commit-id`, `x-gitlab-file-path`, `x-gitlab-file-name`, `x-gitlab-ref`, `x-gitlab-encoding: base64`, `x-gitlab-size: 5869`. Separate bucket: `ratelimit-name: throttle_unauthenticated_api`, `ratelimit-limit: 500`, `ratelimit-remaining: 499` — independent counter from Probe 1's web-throttle bucket, confirmed by both reading 499/500 on their very first respective call within the same second. ## The gotcha These look like two spellings of "give me this file" and return the same bytes, but they are opposite on cacheability (one is CDN-cacheable for a minute, the other is explicitly never-cache) and only the API path exposes the blob/commit SHAs an agent would need to detect "has this file changed since I last fetched it" without re-downloading the body — the web `-/raw/` path's only change-detection signal is its own weak `etag`. They also draw from two disjoint rate-limit pools (`throttle_unauthenticated_web` vs `throttle_unauthenticated_api`), so an agent budgeting against one path's remaining-quota header learns nothing about the other's.
