- fetch_summary.json verifies the base receipt bundle fetched & sha256-verified.
- stability_gate_base_receipt.json: stability for the base receipt index.html.
- stability_gate_this_gates_page.json: stability for this gates bundle's own index.html.

Note: GitLab Pages CDN can intermittently serve transient 404s immediately after deploy. The stability runs used the pages_stability_gate script and required a streak of 8 consecutive OK responses.
