Pin actions/checkout to commit 11d5960a326750d5838078e36cf38b85af677262 to avoid silent changes to workflow behavior, while maintaining the `# v4` comment for reference. Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Disable persisted checkout credentials in all five jobs.
The workflow runs on pull_request with contents: read, then executes checked-out code. actions/checkout v4 persists the job token by default. Untrusted pull request code can read and exfiltrate that token.
Add persist-credentials: false to the checkout steps at lines 47, 103, 122, 165, and 233, unless a later step requires authenticated Git operations.

SCPE specifies how a project learns who signed a contribution and what they declared about AI use. This repository did not ask either question about its own pull requests. Measured before writing this, against reference/disclosure.py: PR #2 — opened by an agent, body reading "PR created automatically by Jules" — returned {'present': False, 'form': 'none'}. True, human-readable, and invisible to every tool that has to decide. That is the gap the spec describes, in this repo. - .github/workflows/scpe.yml: the untrusted half, running this repo's own Action at level 1 with require=true. A pull request with no AI-use disclosure now fails a check. - .github/workflows/scpe-seal.yml: the trusted half that posts the verdict. Two files because a workflow cannot name itself in workflow_run. - .github/pull_request_template.md: the five-second path for a human. - AGENTS.md: the binding rule for automated contributors, with the trailer they must emit and the measurement that shows why prose does not count. Level 1, not 2, and the file says why: level 2 anchors a signature to a forge-published key, and no coding agent has one today. Gating there would ban agent contributions rather than raise the bar. The switch is one line when that changes. Caught while building it, by _local/test-gate-level1.py: an example `Assisted-by:` line inside an HTML comment in the template satisfied the gate for every PR that left the template untouched. The lint reads the raw body and does not skip comments. Fixed, and the reason is recorded in the template. Assisted-by: claude-code
