Cryptographic Git Provenance · Zero Mutable Branch Pointers
Sovereign .patchVault & 40-Char Object Hashes
Every proof in this ledger avoids mutable branch comparisons (mutable branch ref comparisons) and instead locks both parent and head commits to exact 40-character SHA-1 hashes, backed by verbatim git format-patch files hosted directly under /git-proofs/*.patch for independent cryptographic verification via git apply --check or git am.
Nominative Fair Use & Sole Authorship Disclosure: All 35 records in this ledger are authored solely by Patrick Ribbsaeter (@patrickswedish) and publicly verifiable via cryptographic Git SHA-1 commits and self-hosted .patch archives. Referenced brand names and logos are used strictly under nominative fair use to identify the upstream open-source repositories.
