Plex2Shell impact on Felhom: verdict NOT REACHED; R-1241 (P1), R-1242 (P3) opened (register 186 -> 188)

Read-only audit of whether the hacked Plex pod on DooPlex (HM-040, 2026-10-17 -> 10-23) reached Felhom's
secrets. Two no-login doors existed (the Longhorn NFS export and the Longhorn API); neither was used:
nfsd accepted 0 new connections in the window (positive control), no off-schedule Longhorn backup or volume.
Evidence in documentation/audits/plex2shell-felhom-impact-2026-10-23/. The NFS export was narrowed from *
to 10.42.0.0/16 on the operator's yes (host change, not in git). 13-threat-model.md: attacker j and one
boundary row. STATUS: verdict, the P1, one do item.
