Actual two-face projection reduces the free-source test to joint coherence

The original closed annulus graph has P_A=[[I-C_A,X_A],[X_A,C_A]],C_A=(I+exp(2WB_Sigma))^-1,X_A=(2cosh(WB_Sigma))^-1 and X_A²=C_A(I-C_A). Its full kernel is a projection,a single face is not. An actual positive P1 CAR source with this joint kernel would therefore inherit all previous free current/Weyl/native-composite correlations under the old domain/subtraction dictionary without an extra Gaussian premise. The missing physical cross equation is omegaP1(aL*(f)aR(g))=<f,X_Ag>. Three positive source controls share the same face marginals;dephased and product states even share the full diagonal covariance but have four-point values0 andp(1-p). On an actual finite P reducing block,delta=Tr[(I-P)C]+Tr[P(I-C)] gives ||rho-rhoP||1<=2sqrt(delta) for arbitrary positive states. All256 ordered four-field words are independently checked;normal/-OO byte-identical.
Scope: Sufficient identification test for the existing chiral scalar two-face source;no physical purification freely selected from C_A,no complete Dirac vector source or new time. Nonprojection marginals still require higher-word comparison. Quantitative error only inside the tested reducing block;no global control from finite samples. Original P1 measure,joint closed real graph trace/domain and physical cross equation remain open. Prior four-field requirement is sharpened only for the full projection case.
Required premises and original source excerpts
- Test a positive joint CAR source against the full geometric projection
Consider an arbitrary normalized positive state on the specified joint charged two-face CAR algebra,without assuming quasifreeness or U1 invariance. The geometric target is the existing closed chiral annulus graph P_A with both marked faces,W=1/2 and original NS B_Sigma. Actual identity C_source=P_A is an explicit condition of the uniqueness theorem and an unresolved P1 source equation,not a fact inferred from geometry or RP. A finite error test applies only on a genuinely P_A reducing CAR block. Complete Dirac vector source,OS Padm and physical time are not identified with this chiral scalar target. No freely chosen purification supplies missing physical cross correlations.
premise:positive-joint-car-source-tested-against-full-geometric-projector - Do not identify source types
Observable algebra, OS reflection, state, collar operator, time evolution, carrier connection, family holonomy, and readout are distinct data until an original map relates them.
