track1TotalSymmetryStationarityReductionHandoffProjectionCount
plain-language theorem explainer
Audit constant fixing the total-plus-symmetry stationarity reduction handoff at two projection accessors: one certificate-field projection and one integrated one-statement projection. Gravity Track-7 integration work cites it to pin Session 576 bookkeeping. The body is the bare natural-number literal 2.
Claim. The Session 576 audit count of projection accessors for the total-plus-symmetry stationarity reduction handoff equals $2$ (one certificate-field projection and one integrated one-statement projection).
background
The ambient module is the Gravity Track 7 fork-handoff integration lane. It records receipts for parallel forks (Track 1.B stationarity reduction at $N=5$, physical residual/Bianchi, many-body amplitude lift, Page-capacity transfer, dark-energy $w(z)$ bands, and falsifier-sensitivity packaging) without upgrading discovery claims.
This constant is pure bookkeeping for the total-plus-symmetry stationarity reduction handoff: how many projection accessors that handoff exposes. Sibling endpoints in the same file cover Schläfli reduction, displacement-class stationarity leaves, and seven-stationarity packaging; the remaining displacement-class leaves stay as the next dependency.
No upstream lemmas are required. The value is fixed by the Session 576 audit narrative in the doc-comment.
proof idea
Definitional assignment: the natural number is set equal to the literal $2$. There is no tactic proof and no lemma application. The companion equality theorem discharges by rfl against this definition.
why it matters
Keeps the Track 7 handoff ledger honest: the integration module must state exactly how many projection surfaces the total-plus-symmetry stationarity reduction exposes. Downstream, track1TotalSymmetryStationarityReductionHandoffProjectionCount_eq_two pins the count by reflexivity, so later audit or packaging theorems can quote a named constant rather than a magic numeral.
It does not advance the Recognition forcing chain (T0–T8), the RCL, or the mass ladder. It only stabilizes the Gravity master-theorem handoff inventory so remaining Track 1 displacement-class leaves can be closed against a fixed projection count.
