TYPED BANGEL BINDING

- Lesson — concept and versioned source
- ExperimentInput — value, unit and assumption
- ExampleResult — computed or illustrative output
- LearningEvidence — execution environment and limits

PRECONDITION

A learner changes a documented example or experiment.

SEMANTIC OBLIGATION

Explain the governing rule, preserve input units and assumptions, and label executed examples separately from candidate language exports.

POSTCONDITION

Show the result, comparison and evidence appropriate to the supported lesson.

COMPILATION RULE

Elsa is the compiler. Use a declared Bangel grammar profile, independently admit the applicable JP representation and execute through Joanna only where that path is implemented. These fields are documentary contract notation, not parser-verified source. A shared .bangel extension does not prove grammar equivalence.

PROFILE RELATIONSHIP

Related identities: Bangel Workspace; Bangel Language. Preserve each named contract and source status.

IMPLEMENTATION CHECK

Enter physically incompatible units in a formula example; produce an explicit constraint result rather than a plausible-looking numerical answer.

DISCOVERY NAMES

Bangel Physics Lab
These names aid search; current compiler naming remains Elsa.

SOURCE STATUS AND LIMITS

Recovered historical design and project records informed this documentary profile. Original conversations remain private; current implementation and reported historical tests were not rerun.
Recovered status: historical_report_not_fresh_verification.
Historical 100-method local lab; native execution coverage differed by language and checkpoint. Historical evidence has not been rerun in this discovery pass.
