# OBPI-0.1.0-10: Create templates

## Objective

Create minimal templates for PRD, constitution, brief, and ADR artifacts.

## Parent ADR

- **ADR**: [ADR-0.1.0-enforced-governance-foundation](../ADR-0.1.0-enforced-governance-foundation.md)
- **Checklist Item**: #10 (Templates)

## Lane

**Heavy** — External artifact contract

## Allowed Paths

- Create templates at `src/gzkit/templates/`
- Include required sections per GovZero doctrine
- Support variable substitution for scaffolding
- Keep templates minimal (harden based on usage)

## Denied Paths

- Over-engineering templates
- Adding optional sections that inflate ceremony

## Requirements

- PRD template must include: invariants, gate mapping, Q&A, attestation block
- Constitution template must include: purpose, principles, authority
- Brief template must include: objective, parent reference, acceptance criteria
- ADR template must include: intent, decision, consequences, checklist, attestation block

## Acceptance Criteria

- [x] REQ-0.1.0-10-01: `src/gzkit/templates/prd.md` exists with required sections
- [x] REQ-0.1.0-10-02: `src/gzkit/templates/constitution.md` exists with required sections
- [x] REQ-0.1.0-10-03: `src/gzkit/templates/brief.md` exists with required sections
- [x] REQ-0.1.0-10-04: `src/gzkit/templates/adr.md` exists with required sections
- [x] REQ-0.1.0-10-05: Templates render correctly with variable substitution

## Gate Evidence

| Gate | Evidence | Command/Path |
|------|----------|--------------|
| Gate 2 (TDD) | Tests pass | `uv run -m unittest tests/test_templates.py` |

## Evidence

### Implementation Summary

- Completion evidence: Capability is implemented in the current `gz` runtime and validated by repository quality gates.
- Reconciliation date: 2026-02-22
