# Browser workspace measurements

## Verification Boundary

Browser measurements cover standard and full pages at enumerated viewports, expanded and folded navigation, keyboard folding and a docked assistant. Screen-specific Tasks and editor assertions remain owned by their respective modules.

This register records static review at the supplied source commits. The suite exists, but this pass does not run it or mark its conformance verified.

## What This Suite Proves

- Folding adds usable space and retains centering.
- Keyboard folding changes the standard page workspace.
- Docking the assistant preserves both page-width calculations.
- Keyboard folding keeps the standard column aligned.

Bindings that span files are collective: each file contributes only its recorded assertions. The exact anchors are in frontmatter.

## What It Does Not Prove

The register claims only the linked scenario outcomes at this boundary. It establishes no passing deployment result, complete permission matrix or unlisted cross-capability journey. Proposed scenarios and the remaining lifecycle, invariant and race obligations stay in the coverage findings.

## Real Dependencies and Test Doubles

The browser, console components, route builders, menu computation and client provider are real. Demonstration handlers and local fixture stores replace Platform responses; there is no real sign-in or service database in this tier.

## Must Not Be Doubled

Do not replace the console’s routing, menu assembly, provider, destination guards or measured DOM with canned component outcomes. Demonstration responses or the declared controlled refusal are doubles at the response boundary, not substitutes for the console behavior under examination.
