CDN-246 re-drafts the holdout cluster sample after the CDN-245 disjointness audit ruled CDN-244 invalid. The pool combines the five confirmed-disjoint survivors from CDN-244 (Abell 2390, RXC J2228. 6+2036, Abell 370, ZwCl 1358+62, Abell 851) with ten newly sourced clusters from CCCP-extension (Hoekstra+ 2015) and Weighing-the-Giants (Applegate+ 2014, von der Linden+ 2014): Abell 68, Abell 115, Abell 267, Abell 521, Abell 586, Abell 1413, Abell 1914, Abell 2219, Abell 2631, and MS 0451. 6-0305. The audit gatekeeper (cdn245ₐudit. py) was run against cdn246ₕoldoutᵥ2ᵢnputs. json before the lock was issued; it returned PROCEED with 0 exact-name overlaps, 0 near-match overlaps, and Ndisjoint = 15, satisfying the CDN-243 §3 minimum exactly. The audit script is now permanently embedded in the build step — the lesson from the CDN-244 → CDN-245 sequence is encoded in the toolchain, not in human discipline. All value fields in the input schema remain null. This paper locks the sample, not the data. The CDN-247 execution paper will populate values from the named literature sources, record canonical-JSON SHA-256 of the populated file, run cdn242ᵣesidualᵣeduction. py, and score the per-cluster R/M̄ landings against the CDN-243 prediction bands and decision rule. What carries forward bit-identically: CDN-240 locked physics block (ξₜarget = 5. 836, ξgal = 5. 851, Sₑff = 0. 0623, εₛat = 0. 068) ; CDN-242 refined seven-term κ-proxy (b₆ = +21. 98 at ln λ₀ = ln 17. 5) ; CDN-243 prediction bands (S ±0. 10, F ±0. 20, P ±0. 30, E ±0. 05) and PASS/CONFLICT/FAIL decision rule; CDN-244 provenance schema (per-cluster source paper/table for every input, substitutionᵣeason field, SHA-256 discipline). Art Edition with star-field design system (seed 246). Lock: CDN246DISJOINTHOLDOUTV2LOCKED.
