Alternative text

Bounded Actions artifact download with a locally computed digest

The alternative text above is the Feature Gallery's own Markdown alt text for this frame, so the image describes itself identically in the wiki and here.

The interaction the harness performs

Run the registered actions-artifact-download scene in the complete canonical batch; promote only this output after the exact-set, semantic, geometry, font, and hash gates pass.

Fixture the capture batch requires

Fresh owned P0 run root, isolated user data, disposable provider-backed Git fixture, and the exact production bundle on a hidden Win32 desktop.

Privacy gate the capture must pass

capture_gallery_cdp.js runs its renderer privacy assertion before every Page.captureScreenshot call; inspect every original PNG before promotion.

Regenerating this capture

Run these commands in order, exactly as the capture batch records them. Placeholders in angle brackets are the verifier's own run root, fixture path and CDP port.

1. Step 1 of 2

   npx --no-install cross-env RELEASE_CHANNEL=development DESKTOP_SKIP_PACKAGE=1 yarn build:prod

Dated acceptance receipt

No dated receipt under docs/verification/ names material-actions-artifact-download.png. The frame is published without its own dated acceptance document; the build, interaction and privacy evidence for its batch is recorded in HANDOFF.md and in the Feature Gallery's refresh notes instead.
