- 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.

HPMCU watchdog: arm → beat → fire
Outcome tested: A hung A7/flared ends in a counted reset, not a dark panel.
Benchmark (hpmcu_tick): 1.8 ns/op
