nx_breeding.nx

nx_breeding.nx -- certified composable game part: GENETICS / BREEDING (RENAMED from nx_genome.nx 2026-07-26: the basename collided with runtime/nx_genome.nx, an unrelated CREATURE body-plan genome. Two different capabilities, one filename -- whichever a build resolved depended on the include path. Both names were right in their own domain, so the collision was the defect, not either name.) (gamebench capability 30, the Breeders-of-the-Nephelym keystone; program plan Lane B1, board row F1066). A GENOME is a bounded integer trait vector. BREEDING is seeded, deterministic, per-trait inheritance (pick a parent, apply a bounded mutation, clamp to the trait's legal range). This is the axis where a GENERATIVE emitter beats a hand-authored roster BY CONSTRUCTION: a roster is finite; a genome space this size is not (vsbench carries that as HYPOTHESIS until a head-to-head cell measures it -- this part is what makes the hypothesis testable). THE CONTRACT (each clause is a gate tooth): - DETERMINISTIC: same (parents, seed) -> bit-identical child. Replay/lockstep-safe. - BOUNDED HERITABILITY: every continuous trait of a child lies within the parents' span widened by at most the trait's mutation step. Inheritance, not reroll. - UNIQUE OFFSPRING: different seeds -> distinct children (the loottable 0-dup law applied to creatures -- every bred creature is genuinely YOURS, the ownership pillar). - ADULT INVARIANT FAIL-CLOSED: breeding involving a parent below the adult age REFUSES (GN_E_MINOR) with the output untouched, and every emitted child carries age = GN_ADULT_AGE by construction (the nx_card_compile / nx_wardrobe_state law, inherited into the bloodline). - MORPH = the CoC transformation mechanism: a bounded delta to ONE trait, every other word bit-identical -- transformation is a genome edit re-emitted, not a second asset set. - Serializable span rides nx_gamesave like every certified part. LIB, no main (ecosystem convention). license_tier: ORIGINAL No hw writes (Rule 26).
