TYPED BANGEL BINDING

- CustodyReference: acquired evidence identity
- AccountEntry: typed amount and source
- ReconciliationState: explicit disposition
- Statement: source-bound period

PRECONDITION

A custody/accounting event supplies origin, acquisition record, account scope and required profile evidence.

SEMANTIC OBLIGATION

Preserve balances, custody lineage and reconciliation history; assess financial implications only within Mermaid's own boundary without redefining measurement mathematics.

POSTCONDITION

Return a scoped account or reconciliation record with disputes visible. It does not execute a transfer or issue a product permit.

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

Named family identity; separate from color-paper identity.

IMPLEMENTATION CHECK

An unexplained difference or unbound custody reference must remain exposed rather than being erased.

DISCOVERY NAMES

MERMAID; MERMAID-RECON
These names aid search; current compiler naming remains Elsa.

SOURCE STATUS AND LIMITS

Historical reference or specification recovered. Its source status remains visible and is not promoted to a current standalone implementation.
Recovered status: documented_reference.
Documented domain role does not establish a currently deployed standalone engine.
