Procedural Engine

The engine turns a date or seed into a puzzle through a deterministic pipeline. It balances the mechanical requirements of an anagram with editorial qualities such as readability, variety, emotional fit, and difficulty.

The engine is intentionally content-agnostic after registry composition. This keeps authoring concerns in the content pipeline and keeps generation rules testable in isolation.

Read Determinism for the replay contract, Generation for the candidate pipeline, and Quality and difficulty for the editorial layer.
