Serialize recovery windows per hoster account and normalized filename, reserve remote codes across the batch, and keep cancellation responsive while waiting. Reject semantic and malformed file-list baselines instead of treating them as empty accounts, with focused regression coverage and release allowlist updates.
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.
