Seed-42 impulsive-MGA route discovery

This is the reviewed publication bundle for the 100-route seed-42 experiment documented in the route-search tutorial. A finite score means only that the Rust optimizer found an impulsive MGA scaffold under the declared budget; it is not a low-thrust-feasible or competition-valid trajectory.

random, evolutionary, and gemma4 form the blind matched comparison. gemma4-assisted is a separately named follow-up which uses the completed random and evolutionary archives as prior evidence. It must not be presented as an independent fourth arm.

Each arm retains:

• the terminal run.json and immutable protocol.json;
• compact and full accepted-route archives;
• convergence and proposal-rejection logs; and
• the Rust→adapter exchange log, empty by construction for non-agent controls.

Per-request response caches are deliberately omitted because they duplicate adapter responses. The provider prompt and candidate menu are reconstructed deterministically from these exchanges, the adapter, and any digest-pinned prior archives; they are not stored verbatim. The original local work directories remain outside the repository.

Regenerate or verify the comparison from the tutorial directory:

python3 compare_campaigns.py
python3 compare_campaigns.py --check
python3 plot_results.py --check

The experiment has one root seed and parallel coordinated retry is not bit-reproducible. Repeat predeclared seeds before making a general proposer or model-capability claim.
