# Docs Style Guide

Date: 2026-02-16
Purpose: standardized writing and structure for canonical documentation in this repository.

## Scope

This guide applies to canonical docs in:
- `docs/`
- `docs/runbooks/`
- `config/*.md`
- root operational docs (`PROJECT-MASTER-INDEX.md`, `NODA1-SAFE-DEPLOY.md`, `NODA1-README.md`)

Legacy and snapshot docs are excluded from strict linting:
- `docs/consolidation/_node1_runtime_docs/`
- `.worktrees/`
- backup artifacts (`*.bak_*`)

## Required Structure

Every new canonical document should start with:
1. H1 title
2. `Date: YYYY-MM-DD`
3. `Purpose: ...`

Recommended sections:
1. Scope
2. Preconditions
3. Procedure / Steps
4. Verification
5. Rollback / Recovery

## Writing Rules

- Use sentence-case headings.
- Keep sections short and operational.
- Prefer explicit paths and commands.
- Mark runtime facts with concrete dates.
- Avoid mixing strategic legacy notes into canonical runbooks.

## Naming Rules

- Runbooks: `docs/runbooks/<TOPIC>_RUNBOOK.md`
- Decisions: `docs/runbooks/<TOPIC>_DECISION_YYYY-MM-DD.md`
- One-off status snapshots: include date in filename.

## Linting

Local check:
```bash
bash scripts/docs/docs_lint.sh
```

CI check:
- GitHub workflow: `.github/workflows/docs-lint.yml`

Lint scope source:
- `docs/standards/lint_scope.txt`

Note:
- Full historical docs migration is phased; lint is enforced on managed canonical scope first.
