 ### P3-1 — Reduce dual schema ownership incrementally
 
-**Status (2026-08-30): in progress.** All 49 model tables now have an executable, disjoint creation-owner classification. Nine formerly reconciler-created tables—including authentication support and all three email-provider connections—have moved through additive provider-aware migrations with legacy-row preservation, downgrade/retry safety, startup-DDL removal, fresh SQLite runtime proof and generated MariaDB SQL. The Gmail decision migration also closes its missing MariaDB creation path. Twenty-six startup-created tables remain; see `docs/verification/jt-019-schema-ownership.md` and V-194–V-198.

 - **Findings/scope:** JT-019; inventory reconciler operations and move stable schema ownership to EF migrations in small steps.
 - **Dependencies:** provider upgrade fixtures and P2-2 restore safety.
