Mermaid Reconciliation - IF / HOW / THEN logic

Source-backed documentary sequence — execution not rerun

Mermaid Reconciliation / Teal

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

IF / HOW / THEN CONTRACT

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

HOW

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

THEN

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

TYPED EVIDENCE

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

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

RECONCILIATION

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

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Historical reference or specification recovered.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.
