Execute Phase 2 architecture design pipeline. Reviews Phase 1 algorithm candidates for HW feasibility, designs block-level architecture with data paths, builds reference C model in parallel, and iterates with dynamic-convergence review (min 2, max 5 rounds).

<Use_When>

• Phase 1 research is complete and architecture design is needed
• User says "architecture design", "Phase 2", "block design"
• Need HW feasibility evaluation of algorithm candidates </Use_When>

<Do_Not_Use_When>

• Phase 1 research is not complete (run p1-spec-research first)
• Only need architecture review of existing docs (use arch-review)
• Need DSE with multiple architecture candidates (use rat-dse) </Do_Not_Use_When>

Prerequisites

Phase 1 completion required:

• docs/phase-1-research/iron-requirements.json must exist
• docs/phase-1-research/open-requirements.json (optional — absent if P1 had no open items)
• docs/phase-1-research/io_definition.json must exist

If prerequisites are missing: WARNING — recommend running /rtl-agent-team:p1-spec-research. Proceed with available artifacts — orchestrator will adapt scope.

Execution

If $ARGUMENTS contains "--resume":

Task(subagent_type="rtl-agent-team:p2-arch-orchestrator", prompt="Resume Phase 2 architecture design from existing artifacts in docs/phase-2-architecture/ and reviews/phase-2-architecture/. $ARGUMENTS")

Else:

Task(subagent_type="rtl-agent-team:p2-arch-orchestrator", prompt="Execute Phase 2 architecture design. User input: $ARGUMENTS")

Do not perform any work directly. The orchestrator agent manages P1 candidate HW review, parallel architecture design + ref model, dynamic-convergence iterative review, and artifact finalization.

Workflow Notes

• Open Resolution: resolve all OPEN-1-* items from Phase 1 open-requirements.json
• Compliance Check: verify REQ-A-* architecture requirements against P1 iron requirements
• Exit gate includes compliance-pass — architecture must not contradict any iron requirement
