track1TotalSymmetryStationarityReductionHandoffProjectionCount_eq_two

This module is the Gravity Track 7 integration-lane receipt for parallel fork handoffs (Fork A: Track 1.B stationarity reduction at $N=5$; Fork B: physical residual and Bianchi interface; and further tracks). It records what the new endpoints prove without upgrading the discovery claim, and leaves remaining Track 1 displacement-class leaves as the next dependency.

The named count is a Session 574 audit constant for the direct total-plus-symmetry stationarity handoff accessors. By its documentation it tallies exactly two projections: a certificate field projection and an integrated one-statement projection. Sibling endpoints in the same module package Schläfli, displacement-class, and seven-stationarity reduction holds in the same handoff style.

Term-mode one-liner: rfl. The left-hand side is a defined natural-number constant whose body is literally 2, so definitional equality closes the goal with no lemmas or rewriting.

In the Recognition Science gravity stack this is pure integration bookkeeping, not a dynamical claim. Track 7's role is to freeze what the fork handoffs expose so downstream audits can cite a fixed projection tally rather than re-inspect accessors. It sits beside the Track 1 Schläfli, displacement-stationary, and seven-stationarity endpoint holds, and beside Track 2 many-body and Track 6 falsifier-sensitivity packaging. No parent theorem currently depends on it (used_by is empty); its value is the Session 574 audit pin that the total-plus-symmetry stationarity handoff surface has exactly two projection routes. It does not touch T5–T8 forcing, the RCL, or the mass ladder.
