Added the sourced 2022-2025 annual Brazilian administrative editions while keeping deeper Census geography tied to its 2022 snapshot.

Added

• Annual Admin history: Retained IBGE Municipal Mesh editions for Admin 0-2 in 2022, 2023, 2024, and 2025. The reviewed current spine uses the selected 2022 source; the later editions remain separate dated routes.
• Deeper families: Retained 2022 Census district, subdistrict, and neighborhood sources without implying that they have annual successors.

Changes

• Full and downloads: Bound the 16,802 exact compact-history routes and current 27,604-row Admin spine to the corrected Full revision, Display, and three downloadable tiers at the same public version.

The years name IBGE source editions, not effective dates for each polygon. The unpublished local 1.2.8 number was build iteration, not another public release.

Normalized geometry source and material ownership without changing admitted coverage.

Changes

• source_material_identity: Added source-addressable family-bank and crosswalk lineage, licence policy, and material IDs.
• version_owned_paths: Replaced prior version-owned Full, Display, and reference-partition paths with release-scoped successors while retaining admitted coverage.

Optimized family and crosswalk storage without changing geographic content.

Changes

• physical layout: Repacked admitted family and crosswalk Parquets into bounded query-optimized row groups; identities, relationships, and geometry are unchanged.

Current-system baseline reconstructed from admitted release evidence.

Changes

• release: Established the first unified release manifest without changing geometry bytes.

Established a reconstructed historical baseline from retained source evidence.

Changes

• release: Recorded a deterministic pre-ledger baseline.
