  "statement": "Hosted evidence URLs must stay reachable for the life of the campaign, not only until it is approved.",
  "rationale": "The evidence is what you rely on when a complaint arrives, which is typically long after approval — and by then the share link has expired, the CDN path has been reorganised, or the file was cleaned up as part of a migration. Approval is the point at which everyone stops thinking about these URLs, which is precisely why they rot.",

    "A cloud-drive share link is the common failure: many expire on a schedule, and revoking one person's access can silently break it for everyone."
  ],
  "notes": "Partly off-platform: we can fetch the URLs at scan time, but nobody can verify at registration that they will still resolve in a year. The user has to put the files somewhere durable and re-check them at renewal — the research marks the ongoing-monitoring half as an inference rather than a published rule, so it is surfaced as a warning with the check the user should run themselves, not as a finding against the submission.",
