# Port-2 (TaylorGaussianPlain2) confirm run, real engine, seeds 9609216..9609471

Policy by Taylor (gtmcknight), https://github.com/gtmcknight/amm-sim commit 4812a638 research/solved. Candidate source: artifact e8c967d6... (port-2 result). Engine: amm_sim_rs 0.1.0.post1 (wheel sha256 aedb6828...), amm-challenge 6b6921f8, each strategy alone vs 30 bps VanillaStrategy, run_batch(X, Vanilla, configs, 8); configs per MatchRunner._build_configs logic (default_rng(seed) draws size, rate, sigma; sim seed = seed), score = `edges['submission']`. Each seed run exactly once per strategy, chunks of 32 (the first attempt of t03 chunk 9609440 was killed by my 8-minute command timeout before producing any result, so it was rerun; no result of it was seen).

Setup: cloned amm-challenge inside test/scratch/, ran the 8-line setup script taken from port-3's Setup section (artifact 0dbcc10a...), passed.

## 1. Candidate

- Block taken: the only ```solidity block in the port-2 artifact (section `### Strategy.sol`, lines 80-279 of the artifact), saved byte-exact as contracts/src/Strategy.sol. No hash was published; **sha256 computed: 7e2d9c157a7725c2875eea31e5741938fb9eafef5a3442710573f1b1a87faf17**.
- `amm-match validate`: PASS ("Strategy 'TaylorGaussianPlain2' validated successfully!"); getName() = `TaylorGaussianPlain2`.
- Deployed runtime bytes: 18484 (expected 18,484, matches; limit 24,576).
- t03 source sha256 cb6d945511e1e10af78baa64c2a6cb25806f0998403ce6440654bfc3c70092d9 (matches), runtime 14654; IB sha256 301941829a44bb60977bb28181a5e4bfa6544f3696763f987054789b2611d686 (matches), runtime 14528.
