Adds a third comparison arm to measure_signposting_rate(): Task 19c's
first per-code pass (git ref da72bf3, self-coverage allowed) alongside
the existing coarse (b0df1ec) and live corrected per-code arms, pulled
verbatim via the same git-show mechanism (renamed
.measure_load_coarse_impl -> .measure_load_git_impl since it now loads
more than the coarse arm).
Reports both the original delta (self-coverage-allowed rate minus
coarse) and the corrected delta (live per-code rate minus coarse), plus
the self-coverage share of the original delta (queries that fired ONLY
because a component's own aggregate row satisfied its own coverage
check). Verifies percode-fired is always a subset of selfcov-fired
(stopifnot) -- the corrected arm is a strict narrowing of the buggy one,
so the decomposition is exact rather than approximate.
uscogdata
Curated R reader for the Civilytics US Census of Governments finance corpus.
Provides unit-level financial profiles, geographic rollups, and peer comparisons with auditable provenance and built-in cross-vintage correctness. Reads the published corpus (Hive-partitioned parquet + manifest.json) directly from Nextcloud via DuckDB httpfs — no local bulk downloads required.
Status
Under active development (Phase 2 of the cog_pipeline project). See
../cog_pipeline/docs/reader-specification.md for the reader contract this
package implements.
Installation
# pak::pkg_install("gitea.civilytics.org/Civilytics/uscogdata")
Configuration
USCOGDATA_URL— corpus root URL (public Nextcloud share, trailing slash)USCOGDATA_CACHE_DIR— optional override for the manifest cache directoryUSCOGDATA_MANIFEST_TTL_SECS— optional manifest re-fetch TTL (default 3600)
Developer notes
Testing
The package ships a bundled fixture corpus at inst/extdata/fixture_corpus/ —
a 3.6 MB two-year slice (2019 + 2020) of the full corpus covering all 50
states. tests/testthat/setup.R automatically points USCOGDATA_URL at this
fixture, so the full test suite runs offline with no network dependency:
devtools::test() # uses bundled fixture, no credentials required
Releasing against the live corpus
Before cutting a release, run the test suite against the published corpus to catch any drift between the fixture and the real data:
Sys.setenv(USCOGDATA_URL = "<published-corpus-url-with-trailing-slash>")
devtools::test()
When the live-corpus run is clean, strip the fixture from the built package by
adding this line to .Rbuildignore:
^inst/extdata/fixture_corpus$
The test suite is URL-agnostic — setup.R falls back to USCOGDATA_URL when
the bundled fixture is absent, so no test code changes are needed for the
release run or after stripping the fixture.
