Match the record to what the owners were told, and stop the tracker hiding ids

RISK-F-0002's fix_tracking now names ZONE-WP-0001 / WARDEN-WP-0032, with
the superseded pair kept beside it — the register had told ops-warden the
path had changed and then left the old ids in the file.

An unresolvable fix_tracking (TEN-IN-0002 is an intake, not a workplan)
printed nothing at all, which reads identically to a finding with no
tracking. It now says so by name. Both ZONE-WP-0001 and WARDEN-WP-0032
read proposed, which is the true state of the successor.
