+# 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.
