- Nx 22.7 monorepo (pnpm 11.1, TypeScript 5.9, Node 24)
- apps/api: NestJS 11 (CJS conforme CODING-RULES.md PGD-DB-004)
- apps/web: React 19 + Vite 8 (ESM)
- libs/shared/api-interface: Zod contract base
- Docker Compose dev: Postgres 18, Valkey 8, MinIO, Mailpit
- WDS artifacts:
  - design-artifacts/A-Product-Brief/ (5 docs canônicos + 16 dialogs)
  - design-artifacts/B-Trigger-Map/ (hub + 4 personas + feature impact)
- Stack canon: STACK.md v2.2 + CODING-RULES.md v2.0 + brand.md

+# 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.
+
+## On Complete
+
+Run: `python3 {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --key workflow.on_complete`
+
+If the resolver succeeds and returns a non-empty `workflow.on_complete`, execute that value as the final terminal instruction before exiting.
+
+If the resolver fails, returns no output, or resolves an empty value, skip the hook and exit normally.
