Add seed-generator.ts module and seed-gen-cli.ts CLI that produce parametric Push3 variants for initial population seeding. Variants systematically cover: - Staked% thresholds: 80, 85, 88, 91, 94, 97 - Penalty thresholds: 30, 50, 70, 100 - Bull params: 4 presets (aggressive → mild) - Bear params: 4 presets (standard → very mild) - Tax distributions: exponential (seed), linear, sqrt Total combination space: 6×4×4×4×3 = 1152 variants. selectVariants(n) samples evenly so every axis is represented. evolve.sh gains --diverse-seeds flag: when set, gen_0 is seeded with parametric variants instead of N copies of the same mutated seed. Remaining slots (if population > generated variants) fall back to mutations of the base seed. All generated programs pass transpiler stack validation (33 new tests).

/**
|
||
* seed-generator.ts — Generate diverse seed variants for Push3 evolution (#638).
|
||
*
|
||
* Produces parametric Push3 programs that implement the same binary bear/bull
|
||
* logic as optimizer_seed.push3, with systematically varied constants:
|
||
* - stakedThreshold: the staked% cutoff for entering the penalty branch
|
||
* - penaltyThreshold: the penalty value below which bull params are used
|
||
* - bull/bear params: capitalInefficiency, anchorShare, anchorWidth, discoveryDepth
|
||
* - taxDistribution: spacing of the 30-bucket tax-rate lookup thresholds
|
||
*
|
||
* All generated programs:
|
||
* 1. Consume 8 inputs (same DYADIC stack interface as the seed)
|
||
* 2. Produce 4 outputs in valid ranges [0..1e18] for fractions, positive int for anchorWidth
|
||
* 3. Have identical structure to optimizer_seed.push3 (only constants differ)
