Share account-scoped recovery claims with login uploader instances and serialize same-title recovery windows. Reserve direct and recovered file codes consistently, reject reused identities, and cover concurrent singleton recovery plus distinct-code and parallel-success cases.
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.
