0.2.0 — November 7, 2026

The maintainer selected this coherent minor bundle on November 7, 2026: strict Astral/Python development compliance and its verified enforcement.

• Make strict Astral compliance mandatory for Backplane-owned Python development in every mode; preserve consuming projects' independent runtime policies.
• Establish uv-managed Python 3.14.10, locked development and analysis tools, Ruff lint/format, ty and unittest; replace conflicting no-project guidance.
• Enforce four local pre-commit checks and the routine quality gate in hosted Linux, macOS and Windows CI.
• Repair active Python guide quality and add routine syntax/lint/format guards. Retain independently reviewed deeper checks, cognitive measurements, dependency audit and guide-helper behavior coverage/mutation evidence.

This adds engineering baseline obligations and enforcement capabilities, which warrant the maintainer-approved minor increment rather than a repair-only patch. See the strict acceptance record and version-bump record.

Contributor impact: synchronize the declared environment with uv sync --locked --all-groups and use the repository's locked commands. Native product behavior and consumer runtime requirements are unchanged by this bundle. This engineering-baseline release leaves the complete adoption milestone and its operations, external-pilot and OpenCode obligations open. Historical native acceptance retains its original scope. The maintainer explicitly selected 0.2.0 as the first publication; no historical 0.1.0 release is asserted. See the release authority and scope.
