Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Fire a harmonization-recipe suggestion when a requested category still returns rows but structurally excludes component dollars the corpus does hold — closing uscogdata#9, where `cog_spending(category = "Public Welfare")` silently drops aggregate-published `E67`/`E68` in legacy years. + +**Architecture:** `.build_suggestions()` keeps its recipe-candidate query, M/L exclusion, and IG-counterpart attachment untouched. Its sole year test — "the result has zero rows in this year" — gains a parallel qualifying path: "a component code carries nonzero dollars for this government in this year that the verb's own long view structurally excludes." Reachability is decided by anti-joining the real view (`spending_long_harmonized` / `revenue_long_harmonized`) rather than restating its `WHERE` clause, so the trigger tracks the view if it changes. Both verbs inherit the fix from the shared `.verb_spendrev()` call site. + +**Tech Stack:** R (pkg `uscogdata`), DuckDB via DBI, testthat 3e, cli.
