# ADR 0005 — Hardened drivers live in warden-sdk/drivers/
|
|
|
|
**Status:** Accepted (2026-08-25).
|
|
|
|
## Context
|
|
Our own hardware-facing driver code (relays, modbus master, RGA wrapper, HPMCU
|
|
supervisor, devmem/reset ladder, freshness) is the Tier-1 MC/DC target, but it
|
|
currently lives in flare-edge. The kernel driver source lives in an un-versioned
|
|
scratch tree (`flare-edge/research/linux-6.18.46/`).
|
|
|
|
## Decision
|
|
Bring **hardened copies into `warden-sdk/drivers/`** as the canonical source-of-truth,
|
|
each with its HAL seam and a 100% MC/DC host harness. The RV1106 kernel deltas are
|
|
formalized as a patch series in `patches/`. flare-edge consumes warden-sdk later
|
|
(separate, [maintainer]-gated step).
|
|
|
|
## Consequences
|
|
- Realizes the seam architecture (ADR-referenced in `docs/architecture.md`).
|
|
- flare-edge is not edited now; a later integration step points flare-edge at these.
|
|
- Risk: temporary duplication of shared constants between the two repos until the
|
|
integration lands — tracked, acceptable for the bring-up window.
