/**
 * Logo diagnostic must not leak the filesystem layout, and must mirror what
 * resolveLogoFile actually tries (GHSA-29vm, codex round 2).
 *
 * Round 1 relativised `resolvedTo` and the candidate paths but still echoed
 * `sources[].value` verbatim — and branding_logo_path is stored ABSOLUTE by
 * multer, so the layout went out anyway. It also dropped the raw-absolute
 * candidate, which the resolver retains (subject to containment), making the
 * diagnostic report every candidate as missing for a legitimately contained
 * absolute logo while `resolvedTo` named the file.
