### Checkpoint checklist size limit exceeded
**Offending text:**
> - [ ] I can see a newly created PAT in my token list
> - [ ] I copied the token value before leaving the page
> - [ ] I noted the token expiry date
> - [ ] The secret name is exactly `COPILOT_GITHUB_TOKEN`
> - [ ] The secret now appears in the repository Actions secrets list
> - [ ] I closed the token tab only after confirming the secret was saved
> - [ ] You generated a new fine-grained PAT and copied it before leaving the token page
> - [ ] The token has **Copilot requests: Read-only** under **Account permissions**
> - [ ] `COPILOT_GITHUB_TOKEN` exists in **Settings** → **Secrets and variables** → **Actions**
> - [ ] `copilot-requests: write` is not present in the source workflow
> - [ ] The agent recompiled and committed the updated lock file
> - [ ] You set a reminder to rotate the PAT before the expiry date
> - [ ] You understand when to use Method 1 vs Method 2

**Suggested fix:**
The page has 13 checkboxes total across its two "Quick check" mini-checklists (3 + 3) and the final `## :white_check_mark: Checkpoint` section (7), exceeding the "Maximum 10 checkboxes per page" rule in `.github/workflows/guidelines.md`. Trim the two in-page "Quick check" lists down to only the items that aren't already restated in the final Checkpoint (e.g., drop near-duplicates like "I copied the token value before leaving the page" / "I closed the token tab only after confirming the secret was saved" from the Checkpoint since they're already verified inline), or consolidate the Checkpoint list itself to 6–7 outcome-oriented items so the page-wide total is 10 or fewer.

Open workshop/side-quest-06-03c-copilot-github-token-ui-only.md and compare its Quick check and Checkpoint lists with the 10-checkbox limit in .github/workflows/guidelines.md. Remove redundant or consolidate outcome-oriented items while preserving the required checks. Count all page checkboxes and confirm the total is 10 or fewer.
