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.
