Prove scene work landed: snapshot, diff, screenshots, runtime reads, 3D audits, shot sheets and zooms.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Verifying Scenes ## Two signals, two jobs - **Structured state** (`summer_world_snapshot`, `summer_snapshot_diff`, `summer_get_scene_tree`, runtime reads) proves **facts**: paths, classes, transforms, world AABBs, counts, what changed. - **Pixels** (`summer_screenshot`) prove **appearance**: composition, scale-to-the-eye, lighting, "does it read as a forest". Neither substitutes for the other. A diff can say "40 trees added at plausible positions" while the screenshot shows them all untextured magenta; a screenshot can look right while the diff reveals half the trees are unowned and will vanish on save. Run both. ## The before/after discipline Around **every** mutation batch (script, scene tools, import): 1. **BEFORE**: `summer_world_snapshot` — keep `snapshot_id`. First time in a session, also screenshot so you know the starting state. 2. Mutate. 3. **AFTER**: `summer_snapshot_diff from_id:<id>` (omit `to_id` — the engine snapshots now). Check the receipt against your INTENT: - `added` = exactly what you meant to add — no more, no less. …

How to install
mdr add summerengine/summer/verifying-scenes@sha256:fb35dc08dc259db9The line at the top of this page pins the label git:20261016.e9d6e70, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
