How Crate Bloom levels are made and verified
Crate Bloom does not import classic or commercial level packs. Campaign rooms are original project compositions; Daily positions are separately identified, curated mid-game continuations with distinct initial states and reproducible proofs.
Source and identity
Every Campaign room has a stable ID, author, creation date, difficulty and note. The content register records project authorship and license. Daily entries add a pool version, base provenance, checkpoint and verification fingerprint.
Automatic admission
The parser checks one player, equal crate and target counts, legal floor occupancy and bounded dimensions. A push-state solver must finish within 500,000 visited states, and the stored replay must execute every step legally to completion.
Quality and deduplication
Difficulty is based on push decisions and search effort, not board size or long walking. Daily starts cannot equal Campaign starts, pool IDs and fingerprints are unique, at least two pushes remain, and the fixed schedule has no repeat in any rolling 60-day window.
Claim boundaries
The project publishes solver version, node budget, minimum-push result and reference moves. It does not claim dynamic deadlock completeness or globally minimum moves. New content fails closed when source, license, replay or bounded verification is missing.
