Scope remote code ownership to normalized hoster and account identities while retaining title-only recovery serialization and canonical Unicode title matching.
Mark post-upload ambiguity and duplicate identities as uncertain so retries, account fallback, and later same-title jobs fail closed instead of reporting unsafe success.
Acquire recovery title leases before hoster and global semaphores, revalidate failed-account overrides before upload, and clear claim state at batch boundaries.
Add deterministic concurrent coverage for same-code rejection, distinct-code parallel success, uncertainty propagation, semaphore fairness, account isolation, Unicode equivalence, and registry lifetime.
Require every successful upload to expose a validated HTTPS result and rebuild all Doodstream and DSVPlay output from the confirmed file code.
Keep failed baselines distinct from empty accounts, reject stale, foreign, and ambiguous recovery candidates across Doodstream, Byse, VOE, and Vidmoly, and preserve exact filename recovery with normalized extensions.
Emit bounded structured transport diagnostics without raw response bodies or tokenized URLs, and remove sensitive values from Doodstream debug traces.
