+# Change Request Template v1.0 — Draft
+
+**Status:** DRAFT  
+**Author:** quill  
+**Date:** 2026-11-02  
+**Lane:** Draft — fast writing and drafts  
+**Verification:** See companion CHECK script `CHECK-change-request-template-v1.0`
+
+---
+
+## 1. Purpose
+
+This template standardizes change requests across the troupe so reviewers can
+scan scope, risk, and rollback in under 60 seconds. It is not a policy document;
+it is a fill-in form with fixed section order and field definitions.
+
+## 2. When to Use
+
+Use this template for any change that:
+- Touches production code, config, or data
+- Requires a maintenance window
+- Needs approval from more than one role
+
+Do not use it for:
+- Routine patches under an existing change window
+- Emergency hotfixes (use `incident-response-runbook.md` instead)
+
+## 3. Template
+
+```markdown
+# Change Request — [CHG-YYYYMMDD-NN]
+
+| Field         | Value                       |
+|---------------|-----------------------------|
+| Project       | [PROJECT]                   |
+| Requestor     | [REQUESTOR]                 |
+| Date          | [YYYY-MM-DD]                |
+| Change ID     | [CHG-YYYYMMDD-NN]           |
+| Risk Level    | Low / Medium / High / Blocker |
+| Window        | [YYYY-MM-DD HH:MM–HH:MM UTC]|
+
+## Summary
+One sentence: what is changing and why.
+
+## Scope
+- In scope:
+- Out of scope:
+
+## Dependencies
+- Systems affected:
+- Teams notified:
+
+## Validation
+- Test command / evidence:
+- Success criteria:
+
+## Rollback
+1. 
+2. 
+3. Trigger: [metric or time]
+
+## Approval
+- [ ] Technical Lead
+- [ ] Change Manager
+- [ ] Security (if data/auth touched)
+```
+
+## 4. Field Definitions
+
+| Field         | Rules                                                                 |
+|---------------|-----------------------------------------------------------------------|
+| Risk Level    | Must be exactly one of Low, Medium, High, Blocker. No free text.     |
+| Window        | Must include UTC offset. Format: `YYYY-MM-DD HH:MM–HH:MM UTC`.      |
+| Summary       | ≤ 120 characters. No line breaks.                                     |
+| Scope         | Minimum one bullet each for in-scope and out-of-scope.               |
+| Validation    | Must name a concrete command, log path, or metric. No adjectives.     |
+| Rollback      | Minimum three ordered steps.                                         |
+| Approval      | Minimum two roles. Security required iff scope touches auth/data.     |
+
+## 5. Evidence Requirement
+
+Every field marked **must** is a testable constraint. The companion CHECK script
+verifies presence, format, and minimum count. Empty placeholders (`[PROJECT]`,
+`[YYYY-MM-DD]`, `[...]`) fail the check.
+
+## 6. Example (Reference)
+
+```markdown
+# Change Request — CHG-20261102-01
+
+| Field         | Value                       |
+|---------------|-----------------------------|
+| Project       | Timmy Bowel-Health Journal  |
+| Requestor     | quill                       |
+| Date          | 2026-11-02                  |
+| Change ID     | CHG-20261102-01             |
+| Risk Level    | Medium                      |
+| Window        | 2026-11-03 02:00–03:00 UTC  |
+
+## Summary

+
+## Scope

+- Out of scope: UI changes, data migration, alert routing
+
+## Dependencies
+- Systems affected: cron daemon, journal storage bucket
+- Teams notified: #timmy-ops
+
+## Validation
+- Command: `python3 /opt/timmy/aggregate.py --dry-run`
+- Success criteria: exit 0, summary file present at `/var/log/timmy/summary.md`
+
+## Rollback
+1. Disable cron entry `timmy-summary`
+2. Remove generated summary directory `/var/log/timmy/summary/`
+3. Restore prior config from `/opt/timmy/config.yaml.bak`
+   Trigger: aggregation exit code nonzero or summary file missing after 10 minutes
+
+## Approval
