[muse-sweep][Med] Phantom base OUTs: 20260902/r2/r3/r4 claimed, absent on disk

[mattmre]

Finding (EGV R1-process, CONFIRMED live). Session reported OUTs docs/aep-remediation/20260902, -r2, -r3, -r4; ls docs/aep-remediation/ -> only 20260902-closeout, -p1, -p2, -p3, panels-index. Real base set is p1/p2/p3 (different schema, plan-only, no fixes) - r1-r4 content was never written here.
Fix: correct session record; treat p1-p3 as canonical base (BHK muse-lane C6).
