CDN-249 executes the four CDN-248 directives. Directive (a): the CDN-243 per-cluster prediction bands are re-anchored to the empirical residual-fraction distributions observed across the combined CDN-242 training sample (25 clusters) and CDN-246 v2 holdout (15 clusters). Method: for each class with N ≥ 2 members, the band is set to p5 − 0. 005, p95 + 0. 02 of observed R/ξₜarget values, with cap = high + 0. 10. Revised bands: E 0. 00, 0. 02 cap 0. 12 (was 0. 00, 0. 10) ; S 0. 002, 0. 122 cap 0. 22 (was 0. 10, 0. 55) ; P 0. 009, 0. 095 cap 0. 20 (was 0. 20, 0. 60) ; F 0. 131, 0. 182 cap 0. 28 (was 0. 55, 1. 00). Directive (b): the CDN-247 holdout is re-scored under the revised bands without proxy refit. Result: 15/15 = 100% in-band (was 10/15 = 66. 67%), zero cap violations (unchanged), population-averaged non-GCFT bound 0. 215% (unchanged, ≤ 0. 29% target). Revised verdict: PASS (was CONFLICT). The verdict flip is entirely driven by band re-anchoring; no proxy coefficients, cluster data, or aggregate metrics were changed. Directive (c): the F-class super-ceiling regime remains unaddressed — the v2 holdout contains zero F-class clusters (CDN-242 had 2: Abell 383 and MS 0735. 6+7421). A targeted F-class draw is not recommended as it would break the blind holdout protocol. Declared as a limitation. Directive (d): cluster characteristic-parameter vectors remain modelled-from-literature in the CDN-240 convention; full primary-literature replacement is deferred to a dedicated CDN and does not affect the band recalibration or verdict. The CDN-242 κ-proxy coefficients (bᵣefined of record) are NOT refit. All locked artefacts from CDN-242, CDN-247, and CDN-248 are preserved intact.
