Lock the cascade's nature-half deliverable to "reads alive anywhere", not
"implemented" — the holy-grail objective surfaced by probing the generation
cascade.
- D-245 (architecture): the nature layers are accepted only when the
believability litmus passes at randomly-sampled locations across all
habitable bodies/seeds — multi-scale + never-repeating (macro identity,
meso non-stationarity, micro mosaic), coherence + non-stationarity +
intra-class variety + relief + climate-appropriateness, automated screen
under a human sign-off, budgeted -> strict. Q-123: threshold calibration.
- T-1079 (epic, north-star, DoD=D-245) + findings T-1080 (uniform climate
fields), T-1081 (near-zero relief), T-1082 (no water-body generator),
T-1084 (intra-class micro-habitat mosaic), and T-1083 (the repeatable
believability test protocol / D-245 enforcer).
- aliveness_probe bin: the exploratory probe that found these (runs the
deterministic cascade for a body+seed, reports per-district nature +
verdict). Seed for T-1083.
