jared a9de5ba5ab docs: design spec for the uscogdata 0.1.0 public release
Covers the P0 finding that the package cannot read the corpus remotely at
all -- no working default URL, and Hive globs are unsupported over generic
HTTP by DuckDB 1.5.5. Fix is manifest-driven file enumeration (measured:
46,148,034 rows over plain https, identical to the hf:// glob) plus a
working public default.

Also: seven release-readiness fixes, a README restructured for a stranger,
NEWS rewritten as an initial release rather than a pre-release churn log,
and the Gitea-canonical/GitHub-mirror/r-universe distribution mechanics.

jared 2c532bde19 docs: record the two balance_caveats contract facts cog-api#26 must carry
R-CMD-check / check (push) Successful in 3m38s
R-CMD-check / check (pull_request) Successful in 3m35s
Both were settled during implementation and are easy to get wrong from
outside the package:

- coverage_window is corpus-scoped, not result-scoped. It reports the observed
  year extent of every balance subtype, not only those a query returned. The
  sibling field `truncated` is the result-scoped one.
- balance_caveats is present only on cog_balances() results; an API layer that
  assumes it is universal will read NULL from the money verbs.

jared b8189aeb7f docs: caveat 4 needs a year span crossing FY2002, not just a recipe query
Task 4's implementer found that SB195 does not surface for a
recipe query spanning only 2011-2012. .build_series_break_refs() matches
break_year BETWEEN min(years) AND max(years), and SB195's break_year is 2002.

That is correct behaviour rather than a gap: a series lying entirely after the
book -> market change sits on one consistent basis, so disclosing a break it
never crosses would be noise. .build_corpus_break_refs() applies the same rule
deliberately.

The spec's caveat table overclaimed by omitting the span condition. Corrected.

jared 57212e3399 docs: restore recipe= to cog_balances(); the pipeline was right
Corrects this spec. The earlier draft deferred recipe= and proposed adding
summary_categories rows for X40/X41. Both were wrong, and the pipeline state
they were meant to fix is correct and documented.

cog_pipeline/docs/phase_r_harmonization_review.md records the decisions:

- Sec 0.2: the wide era exposes these split families ONLY as aggregates, so
  the recipe join deliberately does NOT filter is_aggregate. Safe by
  construction -- wide rows are aggregate-only, modern rows leaf-only, every
  component year-scoped.
- Sec 1: the planned X40->Z77 harmonization MAP rows were dropped on purpose;
  continuity ships as recipes instead. That is why harmonization_map carries
  no balance-code rows.

The reader already implements this (R/recipes.R, R/spending.R). Verified
against the live corpus rather than trusting the comment: corrections_combined
FY2007, whose wide leg E05 is likewise aggregate-only, returns $906,743,000.

Also withdraws the claim that SB155/156 and SB195/196 contradict each other.
X40 rows after FY2002 are the wide-era SAS column persisting through the era
boundary; they say nothing about a classification-level rename. The two sets
describe different layers.

What survives is one narrow, non-blocking gap: no series_breaks row exists at
2016/2017 for Z77/Z78/X30, though review doc Sec 2 recommended exactly that.
Recorded as out-of-scope item 1 with the SB197-SB202 precedent.

jared 9f9d40e1c3 docs: drop the subtype argument from cog_balances()
balance is the only category_type whose subtype column is not orthogonal to
category. Measured against the crosswalk: 5 of 6 expenditure subtypes and 1 of
7 revenue subtypes span more than one category, but 0 of 5 balance subtypes do.
Balance is a strict tree -- Fund Balances = {general}, Retirement System
Holdings = {employee_retirement}, Insurance Trust Balances = the three trust
subtypes.

Exposing both arguments would admit no useful combination: of the 15 pairs, 3
are redundant and 12 are guaranteed empty for every government in every year,
failing as an empty tibble that reads as "holds none" rather than as a
contradiction.

Dropping it also keeps the verb aligned -- no uscogdata verb exposes a subtype
argument; the API layers its own subtype row filter on top, which cog-api#26
can do for /balances. #25's one-filter requirement is still met, since
category = "Fund Balances" is exactly W01/W31/W61.

Adds two tests: that one-filter equivalence, and an assertion that the
subtype -> category tree holds, so an upstream change making category lossy
fails here rather than in a user's analysis.

jared d7e14156ff docs: design spec for cog_balances(), the uscogdata#25 holdings surface
Requirement 1 of #25 shipped with #11/#12. This specs requirement 2 only.

Records three upstream gaps found while measuring the corpus, which change
the shipping scope:

- X40/X41 carry ~42.7K rows (1967-2011) but have no summary_categories row,
  so they cannot appear in a category_type='balance' view. Both holdings
  recipes span X40/X41 + Z77/Z78, so recipe= would silently return only the
  2012-2016 leg. recipe= is therefore deferred to v2.
- SB195/SB196 attach to fin_code X40/X41, outside the balance view.
- SB197-SB202 attach to flow codes, not the holdings codes, so the FY2016
  termination of X21/X30/X42/X44/X47/Z77/Z78 has no catalogued break.

Caveats 2-4 are therefore surfaced reader-side via a computed coverage_window
rather than through the existing series-break builders.

jared 24e4449be7 docs(plan): per-year population denominator implementation plan
15-task TDD plan covering: gov_population_yearly view, .attach_per_capita
per-year join, pop_source column + multi-note concatenation, cog_find_peers
year arg, cog_peer_compare cohort_year, rollup unavailable-pop exclusion,
provenance updates, cog_explain rendering, vignette, cog_pipeline data
dictionary, and NEWS entry.

Also corrects spec to match existing rollup semantics (side-by-side, not
summed) and adds /plans to .Rbuildignore.

jared cfcda04e0c docs(spec): correct cog_peer_compare signature in per-year-pop spec
Existing function takes a peers argument (caller supplies cohort) rather
than building one internally. Cohort year flows through via an attr on
the peers tibble produced by cog_find_peers.

jared a25ba5f348 docs: spec for per-year population denominators
Design doc for switching cog_spending / cog_revenue / cog_geographic_rollup
per-capita calculations from a static ACS 2018-2022 population to per-year
F-33 population already present in long.population. Covers shifting peer
matching to a user-selectable cohort year (defaulting to most recent
observed year), type-4/5 NA policy, provenance updates, and a new vignette
enumerating denominator sources for future extensibility.

Specs live in /specs (added to .Rbuildignore) since docs/ is reserved for
pkgdown output.
