Summary of Changes

• Updated S2703_spec.json to support the 2024 ACS 5-year data refresh by adding "Subsidized market place coverage alone" to ignoreColumns.
• Resolved upstream column expansion collision: in the 2024 Census release (ACSST5Y2024), Table S2703 expanded from 176 to 182 columns by introducing a new subcategory breakdown under private health insurance alone ("Subsidized market place coverage alone" across Estimate, Margin of Error, and Percent Private Coverage).
• Fixed 401,342 Sanity_InconsistentSvObsValues errors: previously, because the new subcategory was unrecognized by the column map generator, both the parent column ("Private health insurance alone") and the child subcategory mapped to the same StatVar (dcid:Count_Person_WithPrivateHealthInsuranceOnly and dcid:MarginOfError_Count_Person_WithPrivateHealthInsuranceOnly), emitting conflicting observation values for 2024 across all places.
• Preserved historical time-series and schema consistency across survey years 2015–2024 without introducing 9-year historical data gaps.
• Regenerated column_map.json and processed outputs across 2015–2024 (204.5M+ observations over 205k+ geos), confirming 0 sanity errors in report.json.

Code Review

This pull request updates the S2703_spec.json configuration file to include "Subsidized market place coverage alone". The reviewer suggests correcting the spelling to "Subsidized marketplace coverage alone" (as a single word) to align with the US Census Bureau's standard terminology and prevent potential column matching failures.
