The P1 gate is a pixel comparison, so it needs to be a command rather than a paragraph. `tools/verify-screen` renders each screen in the manifest both ways and reports the largest per-channel difference anywhere in the frame. Both renderers are held to the same inputs on purpose: * the reference CLI is the one `build-reference-cli` builds from the revision the exporter is PINNED to -- not `/reborn/target/`, which is a live mount of the other agent's checkout and moves mid-iteration. A pixel disagreement against a moving decoder has a free variable in it and proves nothing. * `--black`, because the screen carries its own background and the CLI's default dim slate stands in for a 3D scene that is not on this screen. * `--primitives --animated`, because the port draws every element at rest and those two flags are what make the CLI draw the same set. NOT `--focus`: nothing is focused at rest. The threshold is 3/255 -- what integer-truncating compositing in the CLI and float rounding on a GPU differ by. Above that is a placement, order or colour disagreement that needs a reason, and the script says DIFFERS rather than pretending a wider tolerance is a result.
