pub fn attest(repo: &Path, command: &str) -> Result<Attestation>Expand description
Run command in repo and, when it passes, write the branch’s receipt to
repo/RECEIPTS_DIR/<branch_slug>.json and commit it. Returns the
attestation either way.
The commit only ever adds: every other branch’s receipt, and any retired single-file attestation, is left exactly where it is. See the write site for why a paired delete is unsafe.
A receipt records a run that passed, so a non-zero command leaves the
receipts directory exactly as it was — the branch’s earlier receipt, if any,
stays committed and unmodified. The returned Attestation::exit_code
carries the failure for the caller to propagate.
