Epic 10: Jurisdiction geography and district context #116

North star

Prove one complete vertical slice before horizontal dataset expansion:

119th-Congress member term
  -> OCD post/division
  -> official 119th TIGER boundary
  -> retained 2024 ACS 5-year district facts (2020-2024)
  -> reviewed metric registry
  -> mart.congressional_district_period
  -> evidence drill-through

Canonical contracts were aligned and merged in PR #115.

Current programme state

Story 10.2 / #117 is IN PROGRESS: implementation and validation tooling are merged; live warehouse validation is the remaining gate.

Merged Story 10.2 work:

• feat: add 119th Congress and 2024 SLD TIGER boundaries #122 — political TIGER acquisition/load support
• feat: add TIGER live validation report #124 — evidence-led tiger-bulk-validate + idempotent replay proof
• fix: fail closed on incomplete 2024 political TIGER manifest #126 — fail-closed frozen 2024 publisher manifest contract

Reviewed official TIGER2024 manifest baseline:

• 56 CD119 ZIPs
• 52 SLDU ZIPs
• 50 SLDL ZIPs
• 158 artifacts total

Do not start #118 until #117 is closed complete with live warehouse evidence.

Active queue

• Story 10.2: Load 119th CD and 2024 SLD boundaries #117 — Story 10.2: 119th CD + 2024 SLDU/SLDL boundaries — live validation pending
• Story 10.3: Link divisions to boundary vintages and crosswalk evidence #118 — Story 10.3: division-boundary + crosswalk evidence — blocked by Story 10.2: Load 119th CD and 2024 SLD boundaries #117
• Story 10.4: Publish packed 2024 ACS congressional-district facts #119 — Story 10.4: packed 2024 ACS congressional-district facts — blocked
• Story 10.5: Define the district metric registry #120 — Story 10.5: district metric registry — blocked
• Story 10.6: Prove congressional district period mart #121 — Story 10.6: congressional district period mart — blocked

Work these in dependency order. Each story gets its own focused branch/PR and stops at its stated boundary.

Gate

slice_proven opens only after #121 is complete and the result is recorded in docs/PROJECT-STATE.md.

Future CVAP, CBP congressional-district, IRS SOI, LODES, USAspending, GAO CPF/CDS, housing, health, education, broadband, immigration, environment, election, crime and FEC expansions remain outside the active queue until their gates open.
