Internal-week brief. Lab finding count to 7 (with Israel-Haredi, Refugia template, Substrate-Symmetric joining the popdec trilogy). Tectonic shifts upgraded with charts + historical analog library.

The popdec wedge now carries Korea-Hungary (Form 2), Korea Lock-In (Form 5), Positive-Case Search (Form 3 falsification test), Israel-Haredi Floor (religious-community structural mechanism), Refugia Template (Form 4), and Substrate-Symmetric Refugia. The cross-citation network is dense enough that reading any one finding pulls a reader through the trilogy + the substrate generalization.

Population-decline corpus expanded to 6 findings

Israel's sustained TFR ~2.85 is predicted ABOVE the 2030-2035 falsifier bar — but the wedge is religious-community structure (Haredi sub-community fertility ~6+, religious-Zionist ~3-4), not policy spend. The finding makes the structural-cultural mechanism explicit: where religious-community substrate exists, fertility floors form independent of policy.

Israel-Haredi finding documents the structural-cultural positive case

The structural-cultural framing extends beyond fertility. Where dense substrate (housing affordability, intergenerational caregiving, neighborhood child-density) exists, demographic resilience clusters. The finding identifies refugia patterns across high-fertility + high-trust + high-civic-engagement clusters that aren't reducible to ideology or policy.
