Selected RIQE research notes and working papers from the cohort archive.
Preprint deriving the r/W^2 null fluctuation scale for adjacent rolling-covariance spectral projectors, including shared-core exchangeability, exact one-pair sign calibration, the finite-window 2 d_sub/(W - 1)^2 benchmark, and boundary-driven sharpness. 24 pp.
Proof-status notes establishing the r/W² fluctuation rate outright, with the sharp constant and matching lower bound resting on two clearly flagged open steps still to be written out. 8 pp.
