# Decisions

Newest first. A decision that changes `docs/design.md` lands in the same commit as the change.

## Decided

| Date | Decision | Reason |
|---|---|---|
| 2026-09-17 | The harness runs on straylight, the same host as `llama-server`. | Owner's choice. One host to secure, and no inference traffic crosses the tailnet. |
| 2026-09-17 | Container runtime is rootless Podman. | It is already the standard runtime on straylight and the owner's other hosts. |
| 2026-09-17 | Implementation is done by Laguna S 2.1 through OpenCode on straylight. Design, specs, measurement and review are done by a stronger model. Ornith-1.5-35B-A3B remains the model the harness serves. | The owner wants to test a local model on real implementation work. Plans must be written as small closed tasks with tests specified up front. |
| 2026-09-17 | M0 is run by the design model, not by Laguna. | M0 is measurement and interpretation, and its findings bind the design. |

## Open

| Decision | Needed by |
|---|---|
| Secret store backend, and where the v0 file's key lives. straylight has no secrets manager today. | M3 |
| Whether cloud-led sessions are ever allowed, and for which data classes. | M6 |
