Insufficient for the goal
Derive existing parity-Gauss rule only from original P1 definitions
Forward source comparison identifies a concrete insertion/localization definition gap. The seed already takes the local net as input; no inverse selection of the gauge net or full P1 compatibility of both models is proved.
For a new attempt: Build no further extension. A later decision needs the originally defined local insertion/sector map with Padm/Gx, state, time, reflection and primitive winding identification. State this gap and stop.
