        is exactly the invoice templates’ declared variables (no problem from
        the shared validator)
      - >-
        is still the declared variables with every optional value absent, an
        organization’s invoice

        not snapshotted it, and its number null

        makes minor units major by the currency’s exponent: cents for USD, none

        appends 1.0’s link, its div left open as 1.0 wrote it, when the HTML
        does not show it
      - leaves HTML that already shows the link as it is
      - leaves HTML that carries the suppression marker as it is
      - leaves the HTML as it is when the invoice has no link
      - htmlBodyOfMessage

# Invoice document data suite

## Verification Boundary

The suite exercises financial calculations and input contracts in an isolated test process. Registration records the existing executable file; it does not report a run or establish product approval.

## What This Suite Proves

The executable assertions exercise this module, but no capability or feature scenario binding is established for this file. Its individual assertion titles remain in the evidence register for subsequent mapping.

## What It Does Not Prove

Pure calculations and doubled collaborators do not establish database persistence, route authorization or deployed behavior. An unbound feature chain remains proposed, and this registration carries no execution result.

## Real Dependencies and Test Doubles

The imported calculation or contract runs with the fixtures and collaborators declared by the test. The evidence register retains those declarations so the boundaries can be inspected.

## Must Not Be Doubled

The calculation or contract being asserted must remain real; replacing it with a predetermined result removes this suite’s evidence.
