F170's CAUSALITY INVERTED: the DC/DD rebuild runs at frame END (after kernel exit)

This record documents the conclusion: F170's CAUSALITY INVERTED: the DC/DD rebuild runs at frame END (after kernel exit) — its absence on the death frame is a CONSEQUENCE of the spin, not its cause; the walk ALWAYS runs with DC=$00/DD=$09. The merged five-cell tape gives the complete intra-frame program, and the true differential is the OBJECT'S BAND VALUE: bands 14/13/12 render fine, band 11 — the top-zone boundary — kills the walk at cursor step $D4.…
