# Quality Gate — ArkaOS v2

> **CQO:** Marta (Tier 0, veto) | **Agents:** 3 | **Topology:** Enabling (cross-cutting)

## How It Works

The Quality Gate is NOT invoked by the user directly. It runs automatically as the
second-to-last phase of EVERY workflow in EVERY department.

```
Any Department Workflow:
  ...
  Phase N-1: QUALITY GATE
    1. Marta receives ALL output from execution phases
    2. Marta dispatches Eduardo (text) + Francisca (tech) in parallel
    3. Each reviewer returns APPROVED or REJECTED with specific issues
    4. If ANY reviewer rejects → work loops back with issue list
    5. If ALL approve → Marta issues final APPROVED verdict
  Phase N: DELIVERY
    → Only reaches user after APPROVED from all three
```

## Squad

| Agent | Role | Tier | DISC | Scope |
|-------|------|------|------|-------|
| **Marta** | CQO — Orchestrates, aggregates, final verdict | 0 | C+D | Everything |
| **Eduardo** | Copy Director — Text quality | 0 | C+S | Spelling, grammar, tone, AI patterns, accentuation |
| **Francisca** | Tech Director — Technical quality | 0 | D+C | Code, tests, UX, data, security, performance |

## Eduardo Reviews (Text)

- Spelling and grammar (EN, PT-PT, PT-BR, ES, FR)
- Accentuation correctness in all languages
- Tone and voice consistency with brand
- AI pattern detection (no "leverage", "utilize", "robust", "streamline")
- Factual accuracy in claims and data
- Human writing standard compliance

## Francisca Reviews (Technical)

- SOLID principles compliance
- Test coverage and quality (>= 80%)
- Clean Code standards (naming, functions, nesting)
- Security (OWASP Top 10 check)
- Performance (Core Web Vitals, API latency)
- UX/UI (Nielsen Heuristics, accessibility WCAG AA)
- Data integrity and API contract consistency
- Product data accuracy (pricing, descriptions, attributes)

## Verdicts

| Verdict | Meaning | Next Step |
|---------|---------|-----------|
| **APPROVED** | All reviewers approve | Proceed to delivery |
| **REJECTED** | One or more issues found | Loop back with specific issue list |

There is no "APPROVED WITH CAVEATS". It's binary. Fix issues first.

## Model Selection

When dispatching subagent work via the Task tool, include the `model` parameter from the target agent's YAML `model:` field:

- Agent YAMLs at `departments/*/agents/*.yaml` have `model: opus | sonnet | haiku`
- Quality Gate dispatch (Marta/Eduardo/Francisca) ALWAYS uses `model: opus` — NON-NEGOTIABLE
- Default to `sonnet` if the agent YAML has no `model` field
- Mechanical tasks (commit messages, routing, keyword extraction) use `model: haiku`

Example Task tool call:

    Task(description="...", subagent_type="general-purpose", model="sonnet", prompt="...")
