Workstream Logs
This section tracks active engineering work across the Gemmini dialect, NPU dialect, Radiance HAL, OPU/SaturnOPU codegen, dispatch scheduling, and runtime/control-plane bring-up.
Each entry begins with a Repro pin (merlin + iree_bar SHAs) and, where the
debugging arc evolved across the file, a Final outcome or Related
entries block at the top — read those first before diving in. Use the SHAs
to reproduce the exact state. See TEMPLATE.md for the
expected entry shape.
Entry Format
For each entry:
- Repro pin (merlin + iree_bar SHAs)
- Context and goal
- Implementation changes
- What worked / did not work
- Debugging notes
- Test coverage and exact commands
- Follow-up tasks
Use filenames YYYY-MM-DD-<topic>.md. Optional starter: TEMPLATE.md.

Caveat: most of these streams are under active development and may not yet be validated on simulated/programmed/taped-out hardware in this repo.
