jared	874347242b	fix(manifest): actionable errors when USCOGDATA_URL is unset or returns non-JSON ... `cog_gov_search()` (and every other verb) used to fail with a cryptic `jsonlite` lexical error when the package's placeholder default URL was hit and the server returned an HTML welcome page that got cached as `manifest.json`. Three guards added: 1. `.check_url_configured()` aborts with class `uscogdata_url_not_configured` when the resolved URL is empty or still contains the `REPLACE_WITH_SHARE_TOKEN` sentinel. Message names both `Sys.setenv(USCOGDATA_URL = ...)` and `options(uscogdata.url = ...)` remediations and points at the bundled fixture. 2. `.fetch_or_cache_manifest()` parses the response body before persisting it. Non-JSON payloads raise class `uscogdata_invalid_manifest` (URL, Content-Type, parse error) and never touch the on-disk cache. 3. Cache writes are atomic via a sibling tempfile + `file.rename`, and existing caches with non-JSON content are silently refetched instead of returning a parse error to the caller. Local-path manifests that aren't valid JSON now surface the same `uscogdata_invalid_manifest` class with file context.	2026-05-27 11:57:31 -04:00
jared	c682e6547d	feat: cog_spending + cog_revenue + cog_explain ... Three core query verbs over the spending_annotated / revenue_annotated DuckDB views. Each verb accepts vector govid, vector years, optional category filter, per_capita flag, and adjust_to_year for CPI-U real-dollar conversion (bundled index). Amounts are returned in full USD (SUM(amt) * 1000) so callers can freely rescale to millions/billions. The $1,000s -> $USD conversion is recorded in provenance$transformations$units_conversion. Every result carries an attr(., "provenance") list matching inst/schemas/provenance-v1.json. cog_explain() prints the structured form via cli or returns the raw list for MCP/JSON consumers. Also: .fetch_or_cache_manifest() now handles local fixture paths so tests can point USCOGDATA_FIXTURE_URL at the pipeline publish_cache/ without a working HTTP server. Tests: 80 pass / 0 fail. devtools::check() 0E/0W/2N (both notes pre-existing / environmental).	2026-04-24 09:49:09 -04:00
jared	f7035049e7	feat: package skeleton — DESCRIPTION, NAMESPACE, session/manifest/cache/views ... Minimal skeleton for uscogdata v0.1. Internal session layer with lazy cog_open(), manifest fetch+validate+cache, view registration placeholder. Depends on DuckDB >=1.0, httr2, jsonlite. inst/schemas/provenance-v1.json ships the structured provenance JSON Schema.	2026-04-23 09:05:54 -04:00
