+# Step 4: Validate & Summarize
+
+## STEP GOAL
+
+Validate CI configuration and report completion details.
+
+## MANDATORY EXECUTION RULES
+
+- 📖 Read the entire step file before acting
+- ✅ Speak in `{communication_language}`
+
+---
+
+## EXECUTION PROTOCOLS:
+
+- 🎯 Follow the MANDATORY SEQUENCE exactly
+- 💾 Record outputs before proceeding
+- 📖 Load the next step only when instructed
+
+## CONTEXT BOUNDARIES:
+
+- Available context: config, loaded artifacts, and knowledge fragments
+- Focus: this step's goal only
+- Limits: do not execute future steps
+- Dependencies: prior steps' outputs (if any)
+
+## MANDATORY SEQUENCE
+
+**CRITICAL:** Follow this sequence exactly. Do not skip, reorder, or improvise.
+
+## 1. Validation
+
+Validate against `checklist.md`:
+
+- Config file created
+- Stages and sharding configured
+- Burn-in and artifacts enabled
+- Secrets/variables documented
+
+Fix gaps before completion.
+
+---
+
+## 2. Completion Summary
+
+Report:
+
+- CI platform and config path
+- Key stages enabled
+- Artifacts and notifications
+- Next steps (set secrets, run pipeline)
+
+---
+
+### 3. Save Progress
+
+**Save this step's accumulated work to `{outputFile}`.**
+
+- **If `{outputFile}` does not exist** (first save), create it with YAML frontmatter:
+
+  ```yaml
+  ---
+  stepsCompleted: ['step-04-validate-and-summary']
+  lastStep: 'step-04-validate-and-summary'
+  lastSaved: '{date}'
+  ---
+  ```
+
+  Then write this step's output below the frontmatter.
+
+- **If `{outputFile}` already exists**, update:
+  - Add `'step-04-validate-and-summary'` to `stepsCompleted` array (only if not already present)
+  - Set `lastStep: 'step-04-validate-and-summary'`
+  - Set `lastSaved: '{date}'`
+  - Append this step's output to the appropriate section of the document.
+
+## 🚨 SYSTEM SUCCESS/FAILURE METRICS:
+
+### ✅ SUCCESS:
+
+- Step completed in full with required outputs
+
+### ❌ SYSTEM FAILURE:
+
+- Skipped sequence steps or missing outputs
+  **Master Rule:** Skipping steps is FORBIDDEN.
