Rtl P3 Uarch Design

Prerequisites

Phase 2 completion required:

• docs/phase-2-architecture/architecture.md must exist
• refc/ directory with C reference model must exist

If prerequisites are missing: WARNING — recommend running /rtl-agent-team:p2-arch-design. Proceed with available artifacts — orchestrator will adapt scope.

Execution

Task(subagent_type="rtl-agent-team:p3-uarch-orchestrator", prompt="Execute Phase 3 uArch design. User input: $ARGUMENTS")

Do not perform any work directly. The orchestrator agent manages domain consultation, parallel uarch design + BFM development, BFM validation gate, and 5-reviewer dynamic-convergence review (min 2, max 5 rounds).

Workflow Notes

• Open Resolution: resolve all OPEN-2-* items from Phase 2 open-requirements.json
• Zero-Opens Invariant: no unresolved OPEN-* items may pass to Phase 4
• Compliance Check: verify REQ-U-* uarch requirements against P1+P2 iron requirements
• Exit gate includes compliance-pass and zero-remaining-opens

P3 Exit Gate: Acceptance Criteria Advisory

Every REQ-U-* in docs/phase-3-uarch/iron-requirements.json should have ≥1 acceptance_criteria entry. This is an advisory check (WARNING, not hard-block):

• If any REQ-U-* has no acceptance_criteria (absent or empty array []): emit WARNING listing the affected REQ IDs
• Prompt uarch-designer to add missing criteria before P3 exit
• Proceed even if some REQ-U-* lack AC — downstream verification will operate at req_ids level (backward compatible)

P3 Exit Gate: Decomposition Completeness Advisory

After iron-requirements.json is finalized, verify decomposition completeness:

1. Read docs/phase-1-research/iron-requirements.json — collect all Critical/High REQ-F-*
2. Read docs/phase-2-architecture/iron-requirements.json — collect all Critical/High REQ-A-*
3. For each Critical/High REQ-F-: check if at least one REQ-U- has it in traces_to
4. For each Critical/High REQ-A-: check if at least one REQ-U- has it in traces_to
5. Report:
   • COVERED: upstream REQ has ≥1 REQ-U-* tracing to it
   • UNCOVERED: no REQ-U-* traces to this upstream REQ → WARNING

This is advisory (WARNING, not hard-block). UNCOVERED Critical requirements should be investigated — they may indicate a decomposition gap or an intentional architecture decision (document rationale if intentional).
