The fixture predated three shipped corpus changes at once: no J rows in summary_categories (it was built before the crosswalk completion), no representation.parquet or code_set.parquet, and a still-dense wide era. Every test in this package and in cog-api runs against it, so both suites were green against a corpus that no longer exists. This is #18's stated prerequisite; it proves nothing about production until it lands. Regenerated from the publish tree at pipeline_commit 83f9715 (schema v6, built 2026-07-29). FY2011 goes from 2,864,212 rows to 496,004 -- 82.7% of the old partition was explicit zeros -- and the fixture now ships all ten publish-tree metadata tables rather than six. The generator's file list is a single constant now, so the copy step and the manifest step cannot drift. Three test repairs, each a real consequence of sparsification rather than a number to bump: test-categories.R "assistance" joined the spending subtype vocabulary with the J-prefix codes. test-spending.R The harmonization block counts rows that exist. Broward's E21/F21/G21 were zero-pads and are gone, so the anchor moves to FL state, whose three NA-mapped rows carry $2.83B -- the amount accounting was previously asserted only against 0 and could not have caught a bug. Broward keeps a test of its own, now asserting the zero-pads are absent. test-expenditure-concept.R Coverage-gap suggestions are presence-based. AL state's only FY2011 B47 cell was an explicit zero, so ig_federal_b47_wide stopped being a candidate there; FL state carries a real amount, so the counterpart guard is exercised against a suggestion that fires. test-fixture-vintage.R pins the structural facts that separate this vintage from its predecessor -- the ten metadata tables, the dense/sparse representation contract, zero explicit zeros in FY2011, code_set coverage, and J19's category. Checked against the old fixture: FY2011 carried 2,368,208 explicit zeros, so the assertion discriminates rather than merely passing. Suites: uscogdata 594 pass / 0 fail / 6 skip (was 576/0/6). cog-api 357 pass / 0 fail / 8 skip against the regenerated fixture, unchanged from its baseline.
