charset=utf-8`, `etag: "7627d6c869ccb698a259260b5626305af9b16a0d820573eb4d5cd0da59c73525"`, body `#include ` (20 bytes) — note the file is C++ source, not plain text, yet the `Content-Type` is unqualified `text/plain` regardless. ## Probe 3 — the "no sha" / always-latest form ``` GET https://gist.githubusercontent.com/mrkimheng14-jpg/3a155b13caa8cdef16b6d672705a6c67/raw/gistfile1.txt ``` Byte-identical body and `etag` to Probe 2 — omitting the sha segment entirely resolves to the current (only, in this case) revision. ## Probe 4 — the gist's own commit/version sha also works in the same slot ``` GET https://api.github.com/gists/3a155b13caa8cdef16b6d672705a6c67/commits ``` `version: "b5ec3ccd452e21fe6331ad8768d67cf8138142fc"` — a **different** sha than the one in `raw_url` (`604782e4...`). Substituting this commit-version sha into the raw path: ``` GET https://gist.githubusercontent.com/mrkimheng14-jpg/3a155b13caa8cdef16b6d672705a6c67/raw/b5ec3ccd452e21fe6331ad8768d67cf8138142fc/gistfile1.txt ``` also returns `HTTP 200` with the same content — so **both** the `raw_url`'s own embedded sha and the separately-fetched `/commits` `version` sha are valid in that path position, even though they are not the same value and come from different parts of the API. ## Probe 5 — a garbage/all-zero sha in the same slot ``` GET .../raw/0000000000000000000000000000000000000000/gistfile1.txt ``` `HTTP 404`, plain-text `404: Not Found` (14 bytes) — confirming the slot really is validated against the gist's actual revision history, not just ignored.
