Carry the geography ladder by default; gate releases on it#289
Merged
Conversation
The ladder shipped opt-in (#277): nothing stopped a base or release from being built without the geography spine, which is the silent-degradation family (#225 everyone-is-a-citizen, #34 NYC-zero) this repo legislates against. - tools/build_us_puf_support_base.py: omitting --block-ladder-artifact is now an error; diagnostic builds opt out explicitly with --without-block-ladder (recorded in the summary). - L0/refit release export: the geography spine (state_fips, congressional_district_geoid, and the seven ladder columns) joins the required release source columns (presence; value quality is the gate's job), and the us_geography_ladder gate runs on the selected support with its calibrated weights — a release whose spine is inconsistent or whose NYC mass collapsed fails by default. --allow-geography-ladder-gate-failures is the diagnostic escape hatch; the gate result is recorded in the export summary either way.

Follow-up to #277 (populace #275). The ladder shipped opt-in: nothing stopped a base or a release from being built without the geography spine — the silent-degradation family (#225's everyone-is-a-citizen, #34's NYC-zero) with a new face. Carrying the ladder is now the default at both enforcement points:
tools/build_us_puf_support_base.py): omitting--block-ladder-artifactis an error; diagnostic builds opt out explicitly with--without-block-ladder, and the opt-out is recorded in the build summary.l0_refit_export): the geography spine (state_fips,congressional_district_geoid, and the seven ladder columns) joinsUS_RELEASE_REQUIRED_HOUSEHOLD_SOURCE_COLUMNS(presence-checked; value quality is the gate's job), and theus_geography_laddergate runs on the selected support with its calibrated weights — a release whose spine is inconsistent or whose NYC mass collapsed fails by default.--allow-geography-ladder-gate-failuresis the diagnostic escape hatch, mirroring--allow-input-mass-drift, and the gate result lands in the export summary either way.Operational note: reconstructions of ladder-less bases (anything built before #277) now require the explicit escape hatches — that is the point.
