# data/ — the bundler's source-of-truth data

**The law: data lives here; `public/` is generated.** Every folder in `data/` is copied into the
served web-root by the build (`internal/generate-tree.mjs`), exactly like the per-profile data in
`plugin-designs/*/data/`. You should be able to `rm -rf public/` and get it all back with `bun run build`.

| Folder | Served at | What it is |
|---|---|---|
| `people-groups/` | `/assets/people-groups/` | People-group datasets (CSV/JSON) the maps read at runtime |
| `vendor/` | `/assets/vendor/` | Third-party runtime assets (e.g. table libraries) |
| `posters/` | `/assets/posters/` | Rendered poster webp set (heavy pipeline output; poster walls fetch these) |
| `tables/` | `/assets/tables/` | The MERGED served table set (its index.json is the merge; per-profile `plugin-designs/*/data/tables` are build-time sources) |
| `external-bundles/` | not served | Prebuilt map IIFEs vendored from sibling projects (not built here); only the optional `layouts/` shell mounted them, so the build no longer copies them into `public/` |

Don't edit anything under `public/` by hand — change it here (or in `plugin-designs/*/data/`,
`layouts/*/assets/`) and rebuild.
