exp016_ct package (content-task heredity: retrieval-judged tournaments, 2 seeds + catastrophic probe; continuity ascends / germline flat both seeds; catastrophe absorbed under continuity - robustness belongs to the regime) + exp015 seed-1 replication amendment (germline bpb neutrality certified; flat fixed point scoped as seed-dependent; tree fixed point replicates)

geolip_vitals: built-in batched Cayley-Menger for pentachoron_cv (one float64 det over all samples, ~260x faster and exact vs the fp64 reference; fp32 reference path loses up to 4% on near-degenerate pentachora) + cv_reference_check() parity gauge against geovocab2

geolip_vitals: pentachoron_cv now imports Cayley-Menger from installed geovocab2 (geolip-svae umbrella layout: shapes.formula.symbolic.CayleyMengerFromSimplex) with the legacy path as first try - CV gauge verified working in all four packages

exp015_ch package (content-bearing heredity: 5 brackets, content gauge, 20 genomes) + repro retrofit: every package standalone (own harness copies, portable data roots, real CLIs, repro.py loaders, genome-aware reader) - all README snippets verified by execution
