# Currency Converter (Live) mechanism

The inspectable method record for Currency Converter (Live), kept separate from implementation and qualification.

Status: **DISPOSED_UNVERIFIABLE_OFFLINE**Lifecycle: **source-required**

## Model scope

This live-data instrument has no offline formula model. Its mechanism is the approved source feed plus visible provenance.

## Units and conventions

Units and conventions must be supplied by the live source and displayed with freshness.

## Inspectable vector

No offline vector is asserted for this source-required instrument.

## Failure boundary

**BREAK_CLAIMED** · SELF_FLAGGED

The specification has no defined handling for extreme finite inputs, so an amount of 1e308 with rate 100 can overflow to Infinity in ordinary floating-point arithmetic. It also leaves the treatment of negative amounts ambiguous. The live/offline cache branch is workable only if the cached timestamp and stale-data status are shown.
