# `Pathfinder/data/` is a published interface

Devon answered on 2026-09-13 (locked decision #350): this is public PF2e
Remaster reference data copied into the site, and **any project may read it.**
It stopped being private to the Anathema Archive that day. The Absalom
Inheritance and Torchbearer had both wanted it for six rounds and had both
stopped short of using it, which was the right call until someone said so.

## What a reader may do

- **Fetch it at runtime** from the same origin, e.g.
  `fetch('../../Pathfinder/data/spell.json')`. It is served from this repo, so
  it is not an offsite request. Check `manifest.json` first: it names every
  category's `file`, its `count` and its `sizeMB`, and several files are over
  a megabyte. The Archive loads only the manifest at boot and a category on
  demand; a game should do the same.
- **Or vendor the slice it needs** into its own folder, the way #17 already
  allows for anything else. Pick this when the page has to boot with no network
  (Torchbearer's rule) or needs three stat blocks rather than 1,414 actions.

## What a reader may not do

- **Write here.** The Anathema Archive area owns this folder, and
  `Pathfinder/fetch json data.py` is the only thing that regenerates it.
- **Depend on a field without a test for it.** A project that reads this data
  adds an assertion to its own suite for every field it relies on, and adds
  `Pathfinder/data/**` to its own workflow's `paths:` list. Then a regeneration
  that renames or drops a field turns that project's CI red on the pull request
  that did it, instead of breaking a live page quietly.

## What the owner owes readers

The Archive may still regenerate or reshape these files. Before merging a
change that renames, moves or drops a file or a field, search the repo for
`Pathfinder/data` and run the suite of every project that turns up.

## Licence

Everything in this folder is Paizo's game content. It comes from the
[Foundry VTT pf2e system](https://github.com/foundryvtt/pf2e)'s compendium packs,
reshaped by `Pathfinder/fetch json data.py`, and every entry keeps the
`system.publication` block that names its source book and licence. As of the
2026-09-23 count, 8,403 entries carry `"license": "ORC"` and 3,660 carry
`"license": "OGL"` (legacy, pre-Remaster books).
