+# Phase 3: Result Aggregation & Iteration
+
+Parse agent outputs, detect issues, generate feedback, and manage the iteration loop.
+
+## Objective
+
+- Parse PHASE_RESULT from each agent's output
+- Aggregate results into unified state
+- Detect issues (test failures, blockers)
+- Generate targeted feedback for affected agents
+- Manage iteration loop (continue or proceed to completion)
+- Output: parsedResults, iteration decision
+
+## Execution
+
+### Step 3.1: Collect Agent Outputs
+
+```javascript
+// Collect outputs from all 4 agents
+const agentOutputs = {
+  ra: results.status[agents.ra].completed,
+  ep: results.status[agents.ep].completed,
+  cd: results.status[agents.cd].completed,
+  vas: results.status[agents.vas].completed
+}
+```
+
+### Step 3.2: Parse PHASE_RESULT
+
+Each agent outputs a structured PHASE_RESULT block. Parse it to extract status and data:
+
+```javascript
+function parseAgentOutputs(agentOutputs) {
+  const results = {
+    ra: parseOutput(agentOutputs.ra, 'ra'),
+    ep: parseOutput(agentOutputs.ep, 'ep'),
+    cd: parseOutput(agentOutputs.cd, 'cd'),
+    vas: parseOutput(agentOutputs.vas, 'vas')
+  }
+  return results
+}
+
+function parseOutput(output, agent) {
+  const result = {
+    agent: agent,
+    status: 'unknown',
+    data: {}
+  }
+
+  // Parse PHASE_RESULT block
+  const match = output.match(/PHASE_RESULT:\s*([\s\S]*?)(?:\n\n|$)/)
+  if (match) {
+    const lines = match[1].split('\n')
+    for (const line of lines) {
+      const m = line.match(/^-\s*(\w+):\s*(.+)$/)
+      if (m) {
+        result[m[1]] = m[2].trim()
+      }
+    }
+  }
+
+  return result
+}
+```
+
+### Step 3.3: Update State with Results
+
+```javascript
+// Update agent states
+state.agents.ra.status = 'completed'
+state.agents.ep.status = 'completed'
+state.agents.cd.status = 'completed'
+state.agents.vas.status = 'completed'
+
+// Update shared context from parsed results
+state.requirements = parsedResults.ra.requirements
+state.exploration = parsedResults.ep.exploration
+state.plan = parsedResults.ep.plan
+state.changes = parsedResults.cd.changes
+state.test_results = parsedResults.vas.test_results
+
+state.completed_phases.push(...['ra', 'ep', 'cd', 'vas'])
+state.updated_at = getUtc8ISOString()
+
+// Persist state
+Write(`.workflow/.cycle/${cycleId}.json`, JSON.stringify(state, null, 2))
+```
+
+### Step 3.4: Issue Detection
+
+```javascript
+const hasIssues = parsedResults.vas.test_results?.passed === false ||
+                 parsedResults.cd.issues?.length > 0
+
+if (hasIssues && iteration < maxIterations) {
+  console.log('Issues detected, preparing for next iteration...')
+  // → Proceed to Step 3.5 (Feedback Generation)
+} else if (!hasIssues) {
+  console.log('All phases completed successfully')
+  // → Proceed to Phase 4
+} else if (iteration >= maxIterations) {
+  console.log(`Reached maximum iterations (${maxIterations})`)
+  // → Proceed to Phase 4 with issues documented
+}
+```
+
+### Step 3.5: Feedback Generation
+
+Generate targeted feedback based on issue type:
+
+```javascript
+function generateFeedback(parsedResults) {
+  const feedback = {}
+
+  // Check VAS results → feedback to CD
+  if (parsedResults.vas.test_pass_rate < 100) {
+    feedback.cd = `
+## FEEDBACK FROM VALIDATION
+
+Test pass rate: ${parsedResults.vas.test_pass_rate}%
+
+## ISSUES TO FIX
+
+${parsedResults.vas.data.issues || 'See test-results.json for details'}
+
+## NEXT STEP
+
+Fix failing tests and update implementation.md with resolution.
+`
+  }
+
+  // Check CD blockers → feedback to RA
+  if (parsedResults.cd.blockers?.length > 0) {
+    feedback.ra = `
+## FEEDBACK FROM DEVELOPMENT
+
+Blockers encountered:
+${parsedResults.cd.blockers.map(b => `- ${b}`).join('\n')}
+
+## NEXT STEP
+
+Clarify requirements or identify alternative approaches.
+Update requirements.md if needed.
+`
+  }
+
+  return feedback
+}
+```
+
+### Step 3.6: Send Feedback via send_input
+
+```javascript
+const feedback = generateFeedback(parsedResults)
+
+// Send feedback to relevant agents
+if (feedback.ra) {
+  send_input({
+    id: agents.ra,
+    message: feedback.ra
+  })
+}
+
+if (feedback.cd) {
+  send_input({
+    id: agents.cd,
+    message: feedback.cd
+  })
+}
+
+// Wait for agents to process feedback and update
+const updatedResults = wait({
+  ids: [agents.ra, agents.cd].filter(Boolean),
+  timeout_ms: 900000  // 15 minutes for fixes
+})
+
+console.log('Agents updated, continuing...')
+```
+
+### Step 3.7: Iteration Loop Decision
+
+```javascript
+// After feedback processing, decide next action:
+//
+// Option A: Issues remain AND iteration < max
+//   → Loop back to Phase 2 (re-spawn or continue agents)
+//
+// Option B: No issues remaining
+//   → Proceed to Phase 4 (Completion)
+//
+// Option C: Max iterations reached
+//   → Proceed to Phase 4 with issues documented
+
+if (hasIssues && iteration < maxIterations) {
+  // Continue iteration loop
+  iteration++
+  state.current_iteration = iteration
+  // → Back to Phase 2
+} else {
+  // Exit loop → Phase 4
+  continueLoop = false
+}
+```
+
+## Iteration Flow Diagram
+
+```
+Phase 2: Agent Execution
+    ↓
+Phase 3: Result Aggregation
+    ↓
+┌─ Issues detected?
+│   ├─ No → Phase 4 (Complete)
+│   └─ Yes
+│       ├─ iteration < max?
+│       │   ├─ Yes → Generate feedback → send_input → Wait → Back to Phase 2
+│       │   └─ No → Phase 4 (Complete with issues)
+```
+
+## Output
+
+- **Variable**: `parsedResults` - Parsed results from all 4 agents
+- **Variable**: `hasIssues` - Boolean indicating if issues were found
+- **Variable**: `continueLoop` - Boolean indicating if iteration should continue
+- **TodoWrite**: Mark Phase 3 completed, Phase 4 in_progress (or loop)
+
+## Next Phase
+
+If iteration continues: Return to Phase 2.
+If iteration completes: Return to orchestrator, then auto-continue to [Phase 4: Completion & Summary](04-completion-summary.md).
