Elsa Compiler - IF / HOW / THEN logic

Source-backed documentary sequence — execution not rerun

Elsa Compiler / Teal

MJ Physics Engineering | Bangel Language | MJos Operating System
Owned and operated by Michael Bangel | Clearwater, Florida

IF / HOW / THEN CONTRACT

IF
The source unit declares its Bangel grammar, dependencies and effects, and its exact bytes are available.

HOW

Parse source, resolve names and modules, check types, units and effects, then lower accepted syntax to the declared JP representation. Preserve source spans and precise diagnostics on refusal.

THEN

Return typed JP-IR or a compile refusal. Compilation does not admit execution or grant MJ permission.

TYPED EVIDENCE

- SourceText: UTF-8 Bangel source
- GrammarProfile: explicit version
- Effects: declared closed set
- CompileResult: JP-IR or source-spanned diagnostic

FAILURE AND MISSINGNESS

Preserve UNKNOWN separately from zero and source identity separately from truth. Missing required evidence remains a typed error or HOLD under the named profile. Failed permission remains DENY.

PROJECT CHALLENGE

An unresolved name, incompatible unit or prohibited recursion must yield its contract diagnostic rather than usable admitted IR.

RECONCILIATION

Append later results or discrepancies to the original evidence; do not rewrite a prediction into an earlier observation.

DISCOVERY NAMES

Elsa/1; ELSA-SEMANTICS
These names aid search; current compiler naming remains Elsa.

SOURCE STATUS AND LIMITS

Current source inspected; these documentary bindings do not report newly executed software or physical tests.
Recovered status: implementation_source.
Use only the exact named source scope; a documentary sequence is not deployment or an authority grant.

RECOVERED HISTORICAL CONTEXT

- Historical scope: Compiles Bangel source and checks its meaning before producing the typed representation consumed by JP and Joanna.
