Conformance
Conformance means an implementation reaches the protocol-defined verification and authorization conclusions for the applicable frozen target. It is narrower than claiming security certification, legal compliance, market adoption or independent external validation.
Evidence ladder
- Protected release commit.
- Immutable tag/GitHub release.
- Cryptographic manifests/snapshots.
- Regression and targeted qualification tests.
- Sealed conformance vectors/clean-room kits.
- BTG-controlled cross-language implementations.
- Unrelated external implementation.
- Independent security/deployment/market evidence.
No lower rung silently upgrades itself into a higher one.
Vector campaign
A useful sealed campaign contains valid and invalid cases. A conforming implementation must accept all valid records and reject all invalid records for the same reasons/semantic rules, then publish reproducible evidence of the run.
Cross-language evidence
BTG publishes Rust, TypeScript, C#, Go, Swift and Java controlled baselines. They demonstrate that the documented semantics can be reproduced outside one Python runtime, but because BTG controls the implementations they are not unrelated third-party validation.
Independent threshold
The stronger external milestone is a repository, architecture and implementation controlled by an unrelated developer or organization, built from public specifications and sealed material rather than BTG implementation code, followed by bidirectional interoperability and sovereign export/recovery survival.
v3.4.2 release evidence
The published release states 203/203 regression PASS, repository safety 3/3 PASS, dependency review PASS, public conformance smoke PASS and protected-state recovery PASS. External ADAM promotion gates listed in the release notes remain post-release work.
Reporting a result
Publish the exact release/tag, environment, commands, vector/kit hashes, pass/reject counts, output hash/root, failures and whether the implementation is BTG-controlled or independent. A reproducible failure or ambiguity is valid evidence and should not be hidden.
