# pbir-authoring-adapter The adapter that completes F034: it writes the committed PBIR report the kit previously left for a human to build in Power BI Desktop.

Publishing to a live workspace is the parked F016 adapter (separate, gated). - It does **NOT** build a dashboard from nothing: it restyles/positions visuals a human authored. "Great professional dashboards" is a design-intelligence layer that would ride on top -- this adapter is the mechanism, not that layer. ## The boundary (carry into every increment) 1. **Allow-list only.** Write ONLY the declared formatting/wiring properties (see `templates/pbir-adapter-contract.md`). Increment A's allow-list: the report's `themeCollection.baseTheme` + its `resourcePackages` item + the BaseTheme resource file.
