 - Use `rivet validate` to verify changes to artifact YAML files
 - Use `rivet list --format json` for machine-readable artifact queries
 - Commit messages require artifact trailers (Implements/Fixes/Verifies/Satisfies/Refs)
+- A Claude Code pre-commit hook runs `rivet validate` before each commit

+- AI provenance is auto-stamped via PostToolUse hook when artifact files are edited (main process only)
+- Subagents must run `rivet stamp all --created-by ai-assisted` before committing artifact changes
+- PreCommit hook runs `rivet provenance apply` then `rivet validate`
