Execute Scout-Builder-Verifier workflow

Execute Scout→Builder→Verifier for embedded tasks with blocked-return safety

Non-competition embedded tasks needing deterministic read-implement-verify without user input gates.

• · goal
• · context (optional)
• · builder_agent
• · scout_agent
• · trace_id

• · {scout, build, verify outcomes}
• · {trace_id, blocked? (phase + reason + risks)}

• · embedded-alg/drv/arch agent
• · embedded-qa agent

Scout, Builder, Verifier agent types configured; no user prompts allowed

• · Scout blocked → return immediately with phase=Scout
• · Builder blocked → return with phase=Build
• · Verifier fails → blocked set with risks list

• · Read-only Scout enforced via prompt constraint, not agentType isolation
• · Single writer (Builder only)
• · Verifier defaults to failure (adversarial)
