A truncated debrid download (in-memory byte counter hit 100% while the
NFS write-back silently dropped most of the bytes) was marked completed.
The 1.1.6 fsync fix closed the debrid-specific hole; this generalizes the
guarantee so "completed" never means a corrupt file on ANY backend.
- IntegrityError + bounded retry: on a corrupt/short result the manager
re-downloads the same source up to 3x (clean start), then surfaces the
task as damaged ("corrupt download:" prefix) instead of completing it.
- verify (size mismatch / empty), debrid (incomplete / post-write / flush),
torrent (BytesMissing), usenet (par2 unrepairable / repair-failed) all
classify integrity failures so they route through the retry/damaged path.
- scanner: a file ffprobe can't read is emitted as a damaged library_item
(reason "unreadable") instead of being silently dropped from the sync.
- tests: manager retry-then-success + retry-exhausted-then-damaged,
verifying->resolving transition, damaged sync item.
- usenet: Par2Verify/Repair return ErrPar2NotInstalled (was nil="verified");
pipeline surfaces it via Result.VerifyNote + WARNING — a download that
shipped parity but couldn't be checked is delivered UNVERIFIED, not verified.
- funnel: pin cloudflared version + verify a baked-in SHA-256 (was `latest` +
ELF-magic only) — a malicious/broken upstream release isn't pulled silently.
- stream: makeReadable verifies the file actually opens after chmod and warns
clearly (NFS root_squash / SMB uid mapping) instead of a cryptic later EPERM.
- WireGuard endpoint pin dropped from the debt list (reseller uses direct
config, no pin).
