- 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).
