Two independent defects in the download path, both surfaced by the same incident (#10982). A failed `io.Copy` was always reported as "failed to write file", because `io.Copy` folds read and write errors into a single return value. A peer-cancelled HTTP/2 stream therefore presented as a filesystem failure and sent an investigation after mount permissions while the disk was healthy. The source is now wrapped in a recorder so the error names the side that actually broke, and a write failure names the `.partial` it was writing rather than the final blob path. The plan runner returned on the first task error with no retry, so one transient stream cancel discarded every file already downloaded in a multi-file materialization. The `.partial` resume machinery already existed but was unreachable because nothing made a second attempt. Transient failures (dropped transport, mid-stream read failure, stall, 5xx, 429) are now retried with bounded exponential backoff and resume from the partial; permanent ones (4xx, checksum mismatch, local write failure, caller cancellation) fail immediately.
