Originals no longer buffer the whole decrypted file in RAM: streamDecrypt hands each secretstream chunk to a sink and the download path writes it to the staged temp file, so peak memory is one chunk regardless of file size. The atomic write moved inside the retry loop; only a TAG_FINAL-authenticated attempt renames; truncation leaves no destination file. Does not close #21 (the streamDecrypt accumulation-buffer recopy stays open). Model: opus-4-8
