Artifact ffea6238e647e626d3827c06fc5aed2ea22b21dc50adc5323c04425f92a0757a:
hexToDigest required exactly digest_len*2 hex characters. zit init writes the sha3-256 policy, so that looked like the only case -- but import-git opens its destination under git's sha1, naming every check-in in 40 hex. So commit rejected the parent of every imported repository and reported it corrupt on a store zit verify called clean. Issue #24.
Length now comes from the name, as artifact §7.2 allows both widths. pack.zig carried the same copy and would have dropped the primary-parent hint the same way; cmd/sync.zig's callers move to the slice form.
commitParentCorrupt now names which step failed. Collapsing an undecodable name, an absent parent and real damage into one sentence is why verify and commit could disagree with no way to tell which was right.
Reproduced on 12 commits and 40 files -- not scale-dependent, and not submanifest-specific: it fires before the S-card branch, so flat imports failed identically. Regression test commits over an imported sha1 history; mutation-proved by restoring the width check. by dmestas on 2026-08-02 07:14:38.
