The Latavis Formula Bridge is an Excel add-in of =LATAVIS.* custom functions that pull platform outputs — with their verification level, confidence cap and provenance — into your own models. The same functions are browsable with an evaluator in the formula catalog (sign-in required).
Every function returns the platform's honesty envelope, not just a value.
The add-in augments the workbook you already have — =LATAVIS.VALUE(…) drops an engine output into a cell as a formula, not a pasted constant. It never replaces your workbook.
Companion functions expose the verification level and confidence cap (LEVEL, PROVENANCE) for any value. A synthetic or unvalidated (L0) result returns a labeled string — never a bare number that looks validated.
When a payload carries no as-of date, the add-in says so. It will not imply a timestamp it was never given.
The add-in calls the platform with your personal API key, so everything it can see is exactly what your account can see.
Counted from the functions.json this add-in ships. Each function's arguments and units are in the API reference.

The add-in is version 0.1.0, a pilot, distributed as a sideloaded Office add-in — it is not an AppSource listing. Download the manifest and add it through Excel's Insert → Add-ins → Upload My Add-in (or your organization's centralized deployment):
=LATAVIS.VALUE(…) — the function list ships in functions.json.
