v1.1.0

Added

• Safe monthly partitioning for audit_events, with atomic populated-table migration,
  row-for-row validation, rollback/finalization, global AuditEvent.Id uniqueness, preserved
  grants and row-security policies, and configurable retention defaulting to seven years. The
  migration and recurring maintenance executable requires a distinct table-owning connection;
  the application role receives no DDL. ADR 0020.
• Opt-in billing cost attribution backed by Databricks system.billing.usage and
  system.billing.list_prices. Tenant-owned job runs are selected in PostgreSQL before one bounded
  warehouse query; fixed SQL, bound parameters, report and price-window proration, corrections,
  explicit currencies, a 500-run limit, polling deadlines and redacted upstream errors preserve
  the existing tenant and HTTP boundaries. ADR 0012.

Changed

• Updated Microsoft.Extensions.Diagnostics.HealthChecks.EntityFrameworkCore to 10.0.11; the
  xUnit/VSTest packages to 4.0.0; Testcontainers.PostgreSql to 4.14.0; WireMock.Net to 2.15.0;
  Databricks setup-cli to 1.14.1; CodeQL actions to 4.37.9; and the pinned .NET 10 SDK container
  digest. All generated lock files were refreshed and the full local and hosted gates passed.

Fixed

• Documentation checks now examine tracked and non-ignored new Markdown files instead of scanning
  ignored personal notes. This keeps local verification reproducible without omitting new release
  documentation.
