TR-CORE-IDENTITY / Bangel and member identities
IF
A source, IR or API object declares its language and version.
HOW
Preserve Bangel .bangel / Elsa compiler / Joanna runtime / JP representation / MJ boundary, and preserve
historical Bangel contracts in their separate target.
THEN
Reject mismatched identities or use only an explicit compatibility profile. Do not infer grammar equivalence
from shared lineage.
CURRENT EVIDENCE
Fresh related language/paper/water checks are in the evidence ledger. The test count is suite evidence, not
proof of every branch in this requirement.
REMAINING REQUIREMENT
Use the source and recorded case evidence to close remaining per-branch, native-host and full-contract coverage gaps.
