Sparsification (cog_pipeline#64, SB194) stopped the corpus storing the wide
era's explicit zeros, which made absence ambiguous:
<= FY2011 dense_source absent => Census published $0
>= FY2012 sparse_source absent => not reported, unknown
A wide-era query whose cells were all $0 had begun returning nothing at all,
with no way to get them back -- strictly less than the reader exposed before,
which is why #64 filed this follow-on.
complete = TRUE fills the requested grid from `code_set` and stamps every row
with value_source: "reported", "census_zero" (amt 0), or "not_reported"
(amt NA). The NA is the point. Filling a modern absence with 0 would invent
data, which is exactly the error the representation contract exists to
prevent -- and it makes this strictly MORE informative than the
pre-sparsification corpus, which could not tell a published zero from an
unreported cell either.
Measured on the fixture, Broward County: FY2011 returns 28 reported + 16
census_zero; FY2019 returns 30 reported + 14 not_reported. The five
categories that walkthrough finding F-006 read as "retired at FY2012" now
report themselves correctly as census_zero before and not_reported after.
Scoping decisions, each of which would invent rows if taken loosely:
- The grid is per government TYPE (code_set.type). Filling against the
union of all types would give a county cells like "state IG transfer to
school districts", indistinguishable from real census zeros.
- NOT is_aggregate, mirroring spending_long/revenue_long. Without it the
grid offers cells those views never return, so each would fill as a
phantom $0.
- Filling happens BEFORE per_capita and inflation, so a census_zero stays
0 through both and a not_reported stays NA rather than becoming 0.
Two new views (36-representation, 37-code_set) are gated on the manifest
LISTING those tables, not on schema_version. Sparsification did not bump the
version -- the fixture this package shipped against until 2026-07-30 was
already v6 and carried neither table -- so a version gate would register a
view over a missing file and fail at CREATE VIEW time on exactly the corpora
the check exists to tolerate. with_corpus_missing_representation() models
that corpus and asserts the abort.
Refused where the fill would be guesswork, both classed
uscogdata_complete_unsupported: a recipe defines its own component codes and
never touches summary_categories; the intergovernmental leg deliberately
keeps aggregate rows (inst/sql/24-ig_long.sql) so its cells are not the ones
code_set describes.
Expected cell sets in the tests are computed from the corpus parquet
directly, never through the verb -- verifying what a filter does through
that same filter proves nothing.
Closes DoD 2, 3 and 4 of #18. DoD 5 (the cog-api follow-on) is filed
separately.
Suite: 658 pass / 0 fail / 3 skip (was 629/0/3). rcmdcheck clean.
CI failed on the previous commit. testthat::test_local() from a checkout was
green, but rcmdcheck was not: under R CMD check the suite runs against the
INSTALLED package, where README.md, vignettes/ and man/ do not exist. Both
newly-activated tests read them through test_path("..", "..", ...) and died
on `cannot open the connection`.
The defect was latent in the committed tests, not introduced here -- they
shipped skip()ped, so CI had never executed either one. Removing the skips
is what exposed it, which is the mechanism working as intended.
Guarded with skip_if_no_source_tree(), so they skip in the installed-package
context that structurally cannot satisfy them. They are NOT thereby unchecked
in CI: the workflow runs testthat::test_local() from the checkout as its own
step before rcmdcheck, and there the paths resolve and the assertions run.
Deliberately not split: test-peer-summary-scope.R's numeric pin needs only
the corpus and would survive check on its own, but it exists to protect the
sentence above it. Separating them would let the prose drift while the pin
kept passing.
Verified locally: test_local 629 pass / 0 fail / 3 skip; rcmdcheck
0 errors / 0 warnings / 0 notes.
C1: spending_long/spending_long_harmonized filter NOT is_aggregate but
ig_long deliberately doesn't (legacy IG lives on aggregate rows), so a
legacy aggregate-only family (e.g. Corrections pre-2012) can survive on
the IG leg while Direct is suppressed. expenditure_concept = "total"
then UNIONs an IG-only figure that reads as a plausible Total, and the
coverage-gap suggestion machinery -- fed the UNION'd result -- saw the
surviving IG row as coverage and stayed silent.
(a) .build_suggestions() is now fed a Direct-leg-only view of the
result (IG rows filtered out before the gap-years computation),
so the recipe hints fire for "total" exactly as they do for
"direct".
(b) Any row where IG has dollars but Direct has none for the same
(year, canonical_govid, category) is now flagged: the row's
`notes` name the recovering recipe (drawn from the Direct-leg
suggestions), and provenance gains an explicit
`expenditure_concept_direct_suppressed` boolean plus an appended
warning on `expenditure_concept_note` -- both cheap for a
downstream consumer (cog-api passes provenance through verbatim)
to test, rather than silently asserting Direct + IG when that
arithmetic didn't happen.
Measured before/after on AL state government, Corrections, 2011:
"total" already correctly returns the corpus's actual IG-only figure
($31,358,000, vs. true Direct of $521,651,000 via recipe =
"corrections_combined"), but before this fix it did so with 0
suggestions and an unqualified "Total = Direct + IG" note; after, it
fires 3 recipe hints and both the row notes and provenance say plainly
that Direct is unavailable through this basis.
C2: the 66 M/L summary_categories rows arrived via cog_pipeline PR #59
with no schema_version bump, so schema_version can't gate "total" --
a pre-#59 corpus can report any supported schema_version and still
have zero M/L category rows, in which case ig_annotated's LEFT JOIN
silently produces NA category/spend_subtype (0 rows for a specific
category, or one invisible NA-subtype group for category = NULL). New
.require_ig_categories() checks summary_categories directly and aborts
with class uscogdata_ig_categories_unsupported, naming PR #59 and
directing the user to a newer corpus.
Reconciles tests/testthat/test-views.R's v4-shaped-corpus test (whose
synthetic summary_categories carries only one E36 row) by asserting
the new guard fires against that same connection, rather than leaving
the two silently contradictory.
Adds schema_version 5 support alongside the existing v4 corpus:
.validate_schema() now accepts a supported set (4, 5) instead of a single
expected version, and cog_spending()/cog_revenue() gain basis =
c("harmonized", "raw"). Harmonized basis routes to new
spending_annotated_harmonized / revenue_annotated_harmonized views built on
spending_long_harmonized / revenue_long_harmonized (REPLACE(harmonized_code
AS item_code), excluding aggregate and NA-harmonized rows); raw basis is
byte-identical to the pre-Phase-R2 behavior. On a v4 corpus, an unspecified
basis silently resolves to "raw" with a provenance note; an explicit
basis = "harmonized" aborts with an actionable message.
Provenance gains basis, basis_note, and a harmonization block
(applied/na_rows_excluded/na_amount_excluded). The five new schema-v5-only
SQL views (harmonized long/annotated views, harmonization_map,
harmonization_recipes, series_breaks_pq) are registered conditionally on
manifest$schema_version >= 5, since DuckDB's read_parquet() errors eagerly
at CREATE VIEW time when the backing file doesn't exist on a v4 corpus.
Fixture corpus regenerated to schema_version 5 / years 2011, 2012, 2019,
2020 (2011->2012 spans the wide-aggregate -> modern-leaf format boundary
needed for the harmonization/recipe work), with the harmonization_map /
harmonization_recipes / series_breaks parquet tables bundled alongside the
existing metadata registries.
Adds inst/extdata/fixture_corpus/ — a 3.6 MB two-year (2019/2020) slice
of the published corpus (OH+VT+WY fixture from cog_pipeline test profile
plus all 50 states). Includes canonical_fips_xwalk.parquet,
summary_categories.parquet, docs/, and a trimmed manifest.json.
setup.R now points USCOGDATA_URL at the bundled fixture automatically,
bypassing HTTP / Nextcloud entirely. DuckDB reads local parquet via the
existing .is_local_path() fast-path in manifest.R; no httpfs required.
session is reset between test files via withr::defer(cog_close()).
helper-fixture.R gains fixture_corpus_path(), a richer skip_if_no_corpus()
that checks the bundled fixture first, and with_fixture_corpus() for
tests that need explicit session isolation.
test-spending.R: adjust the inflate-column test to use 2019 (fixture year)
instead of 2015 (absent from fixture).
Result: 181 PASS / 0 FAIL / 0 SKIP — all tests run against real parquet
data with real DuckDB queries and no network dependency.
