File function
Preserves the geometry-first derivation record of the early Prime-Quad anchors P1–P3 and their mapping to the civil timeline, enforcing strict prime-space, rails-space, and A-space separation.
Highlights
- States the geometry from which the active prime-to-civil controls were drawn (B := Q − 5; M := Q + 25).
- Enforces the mandatory P2 dual-operator protocol, prohibiting 30-year straddling as a single operator.
- Functions as source-history support that does not replace active controls.
Reading context
This is geometry-first source-history support under a non-reactivation guard; active prime-to-civil routing remains File_36 / File_32.
