Cost Methodology & Evidence Inventory

CostSignals publishes 2,500+ canonical public calculator pages across home services, legal, finance, and B2B. The methodology read model is a separate partial editorial inventory: not every record resolves to a current public route, and it does not certify source-to-formula provenance.

Methodology Summary

The canonical public catalog contains 2,512 pages across 109 categories. Separately, the current read model contains 631 resolved editorial methodology records and 1,925 declared source references. Of those editorial records, 459 resolve to a current canonical public calculator config and 172 remain internal or unlinked. Source names are not item-level citations, license verification, freshness checks, or proof of runtime formula use. Raw editorial records that do not resolve to a calculator config are excluded from these totals. Inventory version: methodology_editorial_inventory_v1.
