Guidance for AI coding agents working in this repository.

## What this is

`generat3D`: a Python (>=3.11, numpy) CLI that evaluates Daz DSON scenes
(`.duf` plus a content library) natively on Linux and writes the `.dbz` file
Blender's Diffeomorphic DAZ Importer reads. It replaces the one step that
still needs Daz Studio: exporting the morphed figure (mesh and joint centers)
with Diffeomorphic's `export_to_blender.dsa`. Package `generat3d`, run with
`python -m generat3d`. Only stdlib plus numpy; do not add dependencies.

The design spec lives in `docs/superpowers/specs/`. Read it before changing
scope.

## Clean-room rule

Never decompile, disassemble or otherwise reverse-engineer Daz Studio or its
plugins. Sources allowed: the public DSON spec
(`docs.daz3d.com/doku.php/public/dson_spec/start`), Diffeomorphic's source
(GPLv2 or later, compatible), and reference `.dbz` files exported by Daz
itself. The Daz EULA forbids reverse engineering, and the public spec makes
it unnecessary.

## Daz content is never committed

Reference `.dbz` files and anything else containing Daz geometry, morph
deltas or textures live in the gitignored `corpus/` and must never be
committed: that would redistribute licensed content. Committed fixtures are
`.duf` scene recipes (URIs and dial values only) and DSON snippets written
by hand for unit tests.

## Conventions

- Fail loudly: a silently wrong `.dbz` is worse than none, because
  Diffeomorphic imports it without complaint.
- Placeholders only in code, docs, tests and commits.

## Testing

No test suite yet. Planned: `python -m unittest` from the repo root. Unit
tests always run; reference tests compare against `corpus/` and skip when it
is absent.

## Repo facts

- License: GPLv2 or later (`LICENSE`, header in each source file).
- Work directly on master.
