Executive Verdict

Not yet sufficient for MVP accounting ontology under hard 3-check gate.

Hard-Gate Result (2026-03-22)

Source: logs/deep_accounting_mvp_gate.json

1. document -> posting -> debit/credit account: pass
2. posting -> subconto[1..3] -> counterparty/contract/item: fail
3. Explain one real saldo by movement set: pass

Because check #2 is not fully closed (slot 3 not reproducibly proven), the gate verdict is:

Not yet sufficient for MVP accounting ontology; deeper access is justified for failed checks.

Additional slot 3 recon artifact:

• logs/slot3_recon_report.json
• Summary doc: docs/slot3_recon_2026-03-22.md
• UT compatibility status: docs/ut_compatibility_blocker_2026-03-22.md

What Is Already Strong

1. OData endpoint is stable and metadata is readable.
2. Domain coverage is broad (1189 entity sets).
3. Core document/register joins are reproducible.
4. Subconto linkage is derivable for practical cases (including counterparty/contract/item dimensions), but not yet complete for full 1..3 slot coverage.

Required Next Move

1. Keep OData as baseline transport and canonical contract source.
2. Add deeper access only for the missing hard-check segment (subconto slot 3 closure).
3. Use FoxyLink as primary deeper-access PoC candidate.
4. Treat Universal Tools branch as blocked for current БП 2.0 test contour (no plug-and-play compatibility).
5. Follow execution plan: docs/deeper_access_execution_plan_foxylink_ut_2026-03-22.md.
6. Follow test rollout checklist: docs/test_contour_runbook_foxylink_ut_2026-03-22.md.
7. Re-run scripts/run_probe.ps1 until all three checks pass.
