From 00e8046f7b3b5a7dc3d33e75bb509f92c2b32c14 Mon Sep 17 00:00:00 2001 From: "Brent E. Edwards" Date: Sun, 29 Mar 2026 13:07:22 +0000 Subject: [PATCH 1/2] fix(invariant): persist standalone invariants to database Add a standalone invariants persistence path (ORM model, migration, repository, and UoW wiring) so CLI-added invariants survive process restarts. Refactor InvariantService and invariant CLI service resolution to use DI-backed UnitOfWork persistence while retaining in-memory fallback behavior for compatibility tests. Update Behave and Robot TDD coverage for cross-invocation add/list/remove semantics, remove the #1022 expected-fail inversion, and align M3 verification helpers with persisted behavior.

This caused the SqliteChangeSetStore round-trip test to fail because data was not visible across different session instances. Added session.commit() calls after session.flush() in: - ChangeSetEntryRepository.save_entry() - ChangeSetEntryRepository.delete_for_changeset() - ChangeSetEntryRepository.delete_for_plan() - ToolInvocationRepository.save_invocation() - ToolInvocationRepository.delete_for_plan() This ensures that all database operations are properly committed and visible to subsequent queries.
