"""JitPack artifacts pinned to a commit: "newest" is the default branch's HEAD.
|
|
|
|
Some Android builds depend on `com.github.<owner>:<repo>` at a
|
|
short hash. No registry lists a "latest" for those, and a hash is not a
|
|
version, so the gate's question becomes the only one a commit pin admits:
|
|
is the pinned commit still what the source repository's default branch
|
|
points at? (kuhy, 2026-09-12: chosen over never-expiring allowlist entries.)
|
|
|
|
The answer is every branch head's full sha, default branch first; `evaluate`
|
|
compares by prefix so a 7-, 10- or 40-character pin all work, and reports
|
|
the default head's first ten characters, which is what JitPack accepts as
|
|
a version.
