Eta phase alone does not identify needed spin/reference pair
finding:eta-phase-conventions-do-not-identify-relative-spin-reference-pair
With lambda=detH0 tensor inverse detH1, positive theta determinant is inverse lambda; inverse Dai-Freed determinant is lambda in this convention. TFPT action factor exp(−i pi Delta eta/2) obeys a²=tau_rel^(-1) for vanishing kernels, not a=tau_rel. A Pfaffian application needs actual operator,real structure,kernel and orientation; generic gluing does not identify coefficients.
Scope: Convention/type check, not exclusion of a properly derived relative anomaly theory. No unchecked detailed erratum signs used.
Required premises and original source excerpts
- 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.
