Replace every em dash with real punctuation (rewrites, not hyphen swaps) in docs, code comments, scripts, configs, and the port records; convert en dashes, curly quotes, ellipsis glyphs, arrows, and section signs to ASCII; drop machine-writing tell phrases from living docs. ADR titles now use a colon. The M2 bring-up DTS model string carried an em dash into the patch series and its record echoes; fixed at both, and the full series re-verified to apply cleanly onto pristine 6.18.46. One comment in freshness.h deliberately names the em dash glyph the UI renders as the unknown mark; that is data, kept as prose naming it. Verified: cargo tests (sim, config-lint, rs485-bridge), shellcheck, both driver MC/DC harnesses, patches-apply.

ADR 0005: Driver Source of Truth
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 this repo's 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 this repo 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.
