forge.

The rung above morph. morph samples grammars — but only from laws I wrote. forge mints the laws themselves. A foundry smelts candidate transition rules from a closed rule-DSL, fingerprints each by how it actually behaves, and keeps only the ones that sit measurably far from everything known and that the one oracle can certify into real puzzles. Then the whole generator-generator runs on a law no one wrote.

The ladder, one rung higher

puzz generates puzzles. morph generates puzzle generators — but only by recombining a fixed vocabulary of laws that a human wrote. It can pair push with a Möbius strip; it can never invent a verb it wasn't given. forge is the engine that invents the verbs — and then morph's whole machine runs on top of them.

Three ideas make it work

  • A closed rule-DSL. A law is a short genome of typed primitives — a motion kind (step, slide, leap, bounce), a guard, an enter-effect, a leave-effect (trails!), what a mark means, a heading rule. The language is closed: every well-formed genome compiles to a total, deterministic transition function. That closure is what keeps the invariant oracle honest — whatever the foundry mints, the same BFS certifies.
  • Behavioral fingerprinting. Two genomes can read differently and be the same dynamics, so you can't dedupe by text. Each law is run on a fixed probe world and reduced to a vector: state-space volume, branching, irreversibility, world-mutation, stride, heading-drift. Dynamics become a point in space.
  • Novelty search. The archive is seeded with the fingerprints of every hand-written law (walk, ice, leap, paint). A minted law is admitted only if its fingerprint sits measurably far from everything known — and only if the oracle can certify a real puzzle on it. This is the quality-diversity idea (the MAP-Elites lineage): not "is it good?" but "is it new, and does it work?"

What you're looking at

The foundry tab streams the smelting live: most candidates are derivative (too close to a known law) or inert (the law barely moves) — and the rare admitted one is a genuinely new game form, named for its dominant behavior, with a sample puzzle the oracle already certified. The codex collects them; play any one and morph's inner loop generates levels on a law that did not exist until the machine found it.

Determinism

The candidate line is seeded, so the codex is the same on every machine: the n-th discovered law is a permalink, just like the n-th puzzle was. The discoveries are reproducible.
