Methodology week — Lab corpus crosses 7 findings, tectonic depth-pass lands
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.
A methodology-week. Three new Lab findings expand the population-decline corpus into religious-community structural mechanism (Israel-Haredi), abstract refugia template (Form 4 cross-substrate), and substrate-symmetric refugia (the structural-cultural lens generalized beyond fertility). The tectonic-shifts model upgraded to v3 — categories (active / historical / emerging), depth fields (contrarian read, named positions, watch metrics, historical analogs, track record), 6 historical shifts authored at full depth as the analog library, and chart components added to detail pages. The publishing surface for weekly cadence (this brief) is itself the deliverable this week.
Across the corpus.
Population-decline corpus expanded to 6 findings
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.
Israel-Haredi finding documents the structural-cultural positive case
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.
Substrate-symmetric refugia generalizes the lens
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.
