This note serves as the C1/C2 technical companion to the hard-test layer of the Claim Ladder. On the mod-6 ±1 candidate body U6: = n∈N: n≡±1 (mod 6) we define 5-adic shells Lℓ = [5ℓ, 5ℓ+1) ∩U6, branch-aware orbital coordinates, composite-driven window signals, binned shell profiles, and shift-aware transfer observables between neighboring shells. We also fix the bad-set diagnostics, hard null models, and acceptance criteria used in the measured layer. The scope is deliberately narrow. This note does not claim T4, T5, RH, or an operator lift. Its purpose is to make the underlying measurement protocol public, reproducible, and citable, especially the finding that neighboring 5-adic shells often align much better after an independently estimated transfer shift than without it, and that tail-heavy windows show the same improvement under the same shift in the tested regime.
