BELGI preserves the exact material behind a software-change review so a verifier can derive the verdict again instead of trusting the stored result.
- Specification — Working Draft semantics and technical report.
- Python reference — Runnable replay, conformance, and one-byte tamper witness.
- Go verifier — Run the command-oriented verifier against selected bounded surfaces.
This is research/reference work. The specification is a Working Draft; the two implementations cover explicitly named, bounded surfaces and do not claim production readiness or independent authorship.
The historical origin archive preserves the January 2026 concept archive. It documents lineage; it is not a predecessor specification edition, compatibility source, or priority claim.
