- tools/flowgen.py: generates docs/workflows/<name>.md — one outcome-first mermaid flowchart per workflow the SDK tests (hpmcu watchdog, modbus read, cru ladder, rga offload, relay drive, freshness contract), each stamped with its benchmark ns/op or 100% MC/DC result. Deterministic; reads the cargo-bench trend json. - drivers/README.md: honest Tier-1 (relays + freshness, 100% MC/DC here now) vs Tier-2 (modbus/rga — serious testing + fault-injection + benchmarks via sim models; driver sources migrate in with the flare-edge unification) per ADR-0002/0005.

Relay drive (Tier-1, 100% MC/DC)
Outcome tested: A relay is exported transparently and driven without disturbing a held contact.
Coverage: relays.c — 40/40 conditions, 100% MC/DC (CI-enforced)
