FILES
national-indicators.csv: all default raw values.
<indicator-slug>.csv: default raw values for one concept.
snapshot.json: registry, observations, CPI and unemployment variants,
published GDP growth companion, and acquired source-file metadata.
checksums.json: SHA-256 for distribution files (excluding itself).

CSV DICTIONARY
series_id: stable site series identity (text).
producer_code: original code, or explicit two-leg formula for yield spread.
geography: United States. No regional values in this file.
period: YYYY-MM, YYYY-Qn, or YYYY-MM-DD, kept as text.
value: numeric source level; empty means missing, never zero.
units: original units and scale, including annual-rate and index base.
adjustment: Seasonally adjusted or Not seasonally adjusted.
price_basis: nominal/real basis when relevant; units also state chained year.
transformation: Raw level. Yield spread is a website subtraction, identified
by its status and producer code; it is not an official one-leg observation.
snapshot: acquired version ID.
status: source qualifier where available, or explicit derived status.
source_publication_date: known release/file date associated with this
acquired dataset; not the original publication time of every historical row.
Unknown means the acquired file does not establish publication date.
acquired_at: UTC site retrieval timestamp.
source_url: acquisition endpoint or file URL; documentation in JSON.
source_checksum: SHA-256 of the acquired input file.

TRANSFORMATIONS
Percentage change = 100 * (end/start - 1), requiring positive levels.
Year-over-year = compare the same period in the preceding year.
Absolute change = end - prior; for percent rates this is percentage points.
Quarterly annualized growth = 100 * ((end/prior)^4 - 1).
Real GDP headline uses BEA published growth Table 1.1.1 when available.
Index to 100 = 100 * value/base; comparison base is a shared positive date.
Purchasing-power equivalent = amount * index_end/index_start.
Real wage growth = (1 + nominal decimal growth)/(1 + price decimal growth)-1.
No mixing of SA/NSA, generic resampling, interpolation or chained-dollar sums.
Rounded source inputs can produce calculated growth differing from agency
headline rounding. Raw downloads differ from transformed displayed exports.
