"""JitPack artifacts pinned to a commit: "newest" is the default branch's HEAD.
|
|
|
|
Seven of TachiyomiSY's dependencies are `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 the full HEAD sha; `evaluate` compares by prefix so a 7-, 10-
|
|
or 40-character pin all work, and reports the first ten characters, which
|
|
is what JitPack accepts as a version.
