"""Confirmation tests for OBPI-0.25.0-21 (ADR Reconciliation Pattern).

@covers ADR-0.25.0-core-infrastructure-pattern-absorption
@covers OBPI-0.25.0-21-adr-reconciliation-pattern

Decision: Confirm. gzkit's reconciliation surface already covers the airlineops
adr_recon.py capabilities through ledger_semantics (OBPI state derivation with
anchor analysis), ledger_proof (REQ-proof normalization), obpi_reconcile_cmd
(per-OBPI reconciliation with auto-fix), parse_wbs_table (ADR table parsing),
and _build_adr_status_result (ADR-level aggregation).

The airlineops module's table-sync pattern (writing derived status back to ADR
markdown tables) would violate gzkit's state doctrine: "Do not let derived views
silently become source-of-truth." gzkit computes views on demand from the central
ledger instead.
