- evolve.sh: fix fail-in-subshell bug — run seed-gen-cli as a direct
command so its exit code is checked by the parent shell and fail()
aborts the script correctly; redirect stderr to log file instead of
discarding it with 2>/dev/null
- seed-generator.ts: reorder enumerateVariants() to put
STAKED_THRESHOLDS outermost (192 entries/block) so that
selectVariants(6) with stride=192 covers all 6 staked% thresholds;
remove false doc claim about "first variant is current seed config";
add comments explaining CI=0n is intentional in all presets
- seed-gen-cli.ts: emit a stderr diagnostic when count exceeds the
1152-variant cap so the cap is visible rather than silently producing
fewer files than requested
- test: strengthen n=6 test to assert all STAKED_THRESHOLDS values are
represented in the selected variants

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).

Replace per-candidate Anvil+forge-script pipeline with in-process EVM
execution using Foundry's native revm backend, achieving 10-100× speedup
for evolutionary search at scale.
New files:
- onchain/test/FitnessEvaluator.t.sol — Forge test that forks Base once,
deploys the full KRAIKEN stack, then for each candidate uses vm.etch to
inject the compiled optimizer bytecode, UUPS-upgrades the proxy, runs all
attack sequences with in-memory vm.snapshot/revertTo (no RPC overhead),
and emits one {"candidate_id","fitness"} JSON line per candidate.
Skips gracefully when BASE_RPC_URL is unset (CI-safe).
- tools/push3-evolution/revm-evaluator/batch-eval.sh — Wrapper that
transpiles+compiles each candidate sequentially, writes a two-file
manifest (ids.txt + bytecodes.txt), then invokes FitnessEvaluator.t.sol
in a single forge test run and parses the score JSON from stdout.
Modified:
- tools/push3-evolution/evolve.sh — Adds EVAL_MODE env var (anvil|revm).
When EVAL_MODE=revm, batch-scores every candidate in a generation with
one batch-eval.sh call instead of N sequential fitness.sh processes;
scores are looked up from the JSONL output in the per-candidate loop.
Default remains EVAL_MODE=anvil for backward compatibility.
Key design decisions:
- Per-candidate Solidity compilation is unavoidable (each Push3 candidate
produces different Solidity); the speedup is in the evaluation phase.
- vm.snapshot/revertTo in forge test are O(1) memory operations (true
revm), not RPC calls — this is the core speedup vs Anvil.
- recenterAccess is set in bootstrap so TWAP stability checks are bypassed
during attack sequences (mirrors the existing fitness.sh bootstrap).
- Test skips cleanly when BASE_RPC_URL is absent, keeping CI green.

- Add virtual to Optimizer.calculateParams() for UUPS override
- Create OptimizerV3.sol: UUPS-upgradeable optimizer with transpiled Push3 logic
- Update deploy-optimizer.sh to deploy OptimizerV3 instead of Optimizer
- Add ~/.foundry/bin to PATH in evolve.sh, fitness.sh, deploy-optimizer.sh
