Rule order

One turn at the table

  1. Observe. Find the unresolved cells with the smallest weighted mini-deck.
  2. Roll. Row and column dice keep rolling until they hit one of those tied cells.
  3. Collapse. Draw one weighted card from that cell’s current mini-deck.
  4. Propagate. Remove incompatible neighbor cards until nothing else changes.
  5. Audit. Optionally apply the nonlocal “each sealed room needs a door” rule.

There is no second deck: every square already holds its own filtered copy of the master deck. “Observe and collapse” are the usual algorithm terms; decoherence belongs to the quantum metaphor.

Built as a small, inspectable constraint system. Local validity does not promise one connected dungeon.
