# RRC HOLD Closure Checklist

**Date:** 2026-05-09

**Hygiene refresh:** 2026-05-10

This document gives each Rainbow Raccoon Compiler HOLD object a concrete closure checklist.

## Summary

- Compiler receipt hash: `c006c48939fd12a280642e4fb70841fe502641d4c80233bef00b3c710e3f31ba`
- HOLD objects: `6`
- Candidate objects: `1`
- Open closure items: `0`
- Gatekeeper status: `11/11` checklist closures are now `CLOSED`

The checklist closures are closed as documentation gates only. The objects
remain `HOLD` until the Rainbow Raccoon compiler is rerun and emits promotion
decisions from the refreshed receipts.
