End-to-end flow

Step procedure

Step	Actor	Action	Exit criteria
1	Human	Freeze drivers, QA scenarios, risk	Inputs reviewable
2	Architect	Restate forces and non-goals	Shared understanding
3	Alternatives Generator	Produce ≥2 viable options	Options table
4	Architect	Score vs QA scenarios	Winner + rejects
5	Failure Walker + Threat Mapper	Degraded modes + trust edges	Findings listed
6	Architect	Write ADR + Mermaid	Required sections present
7	Independent reviewer	Approve / conditions / reject	Named decision
8	Planner	Implement only within ADR	Plan cites ADR ID

Deviation rule

If implementation needs a different topology, stop coding and revise the ADR — do not silently diverge.

Parallelism rule

Threat and failure walks can run in parallel after alternatives exist. Final ADR decision is serial.
