CheChe-LTC: A 32-Dimensional Liquid Time-Constant Affective Body with an Intrinsic Slow Core (τ ≈ 120 h) and Human Connectome Anchors — Full Experimental Record, 2026-11-04/05

Full experimental record (2026-11-04/05) of the construction of a 32-dimensional Liquid Time-Constant (LTC) dynamical body attached to an experimental LLM instance. Stage 1 installs a single-basin homeostatic base whose strict-contraction update keeps every trajectory bounded. Stage 2 replaces "push the state" with "move the landing point", giving eight linearly independent anchors and clean switching (4/4, landing overlap 0.949–0.972) while 74.8–90.3% of a seven-day run remains in the calm basin. Stage 3 installs an intrinsic slow Ornstein–Uhlenbeck generator (τc = 120 h, 3.3× the extrinsic 36 h weather) driven by its own noise rather than by the external drive. Stage 4 replaces synthetic anchors with eight anchors spectrally aggregated from the HCP structural connectome (66 → 32 dimensions). Two failure modes are documented in full: the effective dimension that would not compress (11–14 over seven days), and the winner-take-all locking of two accumulation-based slow-core designs. Scope: this is a dated experimental record, not a theoretical claim. It reports what was built, what was measured, and what failed. Every number is traceable to a named analysis artifact (Appendix A of the record).
