The last of the four deepening tracks. The world is no longer just a stage the creatures live on; it now has a past and a future.  **Geology.** Every cell carries strata (sediment/granite/limestone/shale), a mineral vein (flint/quartz/stone), and a weathering scalar. Wet exposed ROCK becomes SOIL on a ~50k-tick clock — measured, not asserted: 764 conversions (3.11% of subsoil) in 100k ticks, 186 veins at worldgen, zero columns losing soil depth. The vein tag survives weathering; digging yields mineral-tagged carries; geophagy now targets veins.  **Climate.** Two hands: millennial drift (±2.7°C, 1M-tick period) and deterministic extreme pulses (drought/frost, 15% of years, stateless hash schedule). The drift is deliberately symmetric to protect the v0.27 annual-mean-T certification — and the honest finding is that it produces no detectable slope at feasible probe scales (Δ vs 40k ticks: nothing). The design said it plainly: instruments, not imposed equations — if the probes don't move, that's a finding, not a tuning exercise. The pulses DO bite: fruiting seasonality shifts Δ=40.8.  **Trophic.** A 2400-tick census, a kill ledger (predator→prey), overgrazing stress. Honest finding: no cascade at light-ecology densities — grubs doubled, crop only rose 5% (a cascade needs the drop to exist).  **Succession.** Plant loci colonizer/longevity: germination thresholds and maxAge, r/K selection written into the genome. Honest finding: burned plots don't re-establish — zero germinations on ignited cells in 100k ticks; mechanism unit-tested, the probe couldn't create the conditions.  **Coevolution.** Plant tannin × creature detoxTol: gut survival and fruit nutrition as an arms race. Honest finding: tannin allele lost (0.212→0.000), detoxTol static — no coevolution visible at 40k-tick scale.  **Determinism made checkable.** worldStateHash: FNV-1a 64-bit over grid/scalars/strata/vein/weather, sky, plant allele means, census, tick. P1: 3 seeds × 100k ticks, 30/30 checkpoints match across separate processes.  Probes: P1 PASS (deep-time determinism), P6 PASS (10/10 seeds viable, tick-0 identical), P7 PASS (geology visible). P2–P5: honest findings, not structural failures — mechanisms implemented and unit-tested, not observable at probe scales with light ecology.  Gates: 193/193 material (180 + 13 new D4 tests); founder parity holds; adversarial PASS (in_reach 100.0%, avgBs 0.469, fruitEaten 600, action_table 33/33, zero console errors). CI green on the push (run 37478459231).
