# architecture/ — per-system detail

This repo's pipeline is small enough that `.agents/wiki/ARCHITECTURE.md` covers
it end to end today; nothing has grown large enough yet to need its own
per-system doc here. Split a topic out into this folder (and link it from
`ARCHITECTURE.md`) when it does — likely candidates as the repo grows:

- Retarget-tool internals (per-source rig mapping, bone-name conventions).
- Loop QC/fix algorithms (pose-gap, velocity-gap, root-drift math).
- The exchange-folder state machine (`exchange/GUIDE.md` currently owns this —
  promote here if it needs architecture-level treatment beyond an operator
  guide).
