+# Documentation Escalation Policy
+
+When a documentation issue cannot be resolved at the contributor level, it escalates.
+
+## Levels
+
+| Level | Who | Scope | Example |
+|-------|-----|-------|---------|
+| 1 | Contributor | Own changes | Fixing a typo |
+| 2 | Reviewer | PR scope | Resolving a doc structure disagreement |
+| 3 | Maintainer | Project scope | Policy change affecting all docs |
+| 4 | Project lead | Cross-project | License or safety doc changes |
+
+## Rules
+
+- Escalate only after attempting resolution at the current level.
+- Document the escalation in the PR or issue comments.
+- Higher levels can delegate back to lower levels.

+# Documentation Exception Policy
+
+An exception allows a deliberate deviation from a documentation standard.
+
+## When to Use
+
+- A document must be published before all standards can be met.
+- A legacy document cannot be updated without breaking external references.
+- A temporary situation requires faster publishing than full compliance allows.
+
+## Requirements
+
+- The exception must be documented in the decision log.
+- The exception must include a reason and an expiry date.
+- The exception must be reviewed at expiry.
+
+## Related
+

+# Documentation Minor-Edit Policy
+
+Minor edits can be made without full review.
+
+## What Counts as Minor
+
+- Typo fixes
+- Link corrections
+- Formatting improvements (tables, lists, headings)
+- Updating version numbers
+- Clarifying wording without changing meaning
+
+## What Requires Full Review
+
+- Adding or removing sections
+- Changing policy statements
+- Adding or removing claims
+- Restructuring documents
+
+## Process
+
+Minor edits can be committed directly to `main` or submitted as a PR with
+the `minor` label. Review is optional but encouraged.

+# Documentation Retirement Policy
+
+Documents that are no longer accurate or useful should be retired, not
+left to accumulate.
+
+## When to Retire
+
+- The document describes a process that no longer exists.
+- The document has been superseded by a newer version.
+- The document is inaccurate and cannot be fixed.
+- The document has no identifiable audience.
+
+## Process
+
+1. Add a deprecation notice at the top of the document.
+2. Update cross-references to point to the replacement.
+3. After one review cycle, move the document to an archive directory.
+4. After two review cycles, delete the document.
+
+## What Not to Retire
+
+- Evidence documents with historical benchmark results.
+- Decision logs.
+- Documents that are referenced by external publications.

+# Documentation Review Cadence Policy
+
+Documents are reviewed on a regular cadence to ensure freshness.
+
+## Cadence
+
+| Document Type | Review Cadence | Trigger |
+|---------------|:--------------:|---------|
+| Policy docs | Every 6 months | Calendar reminder |
+| Getting-started guides | Every 3 months | Or after a CLI change |
+| Evidence docs | Every 6 months | Or after a benchmark change |
+| Concept cards | Annually | Or after a related policy change |
+| Runbooks | Every 3 months | Or after a workflow change |
+
+## Process
+
+1. Reviewer checks accuracy, completeness, and link health.
+2. Outdated docs are updated or flagged for retirement.
+3. Review results are recorded in the decision log.
