  "summary": "This pull request migrates transaction persistence in SQLite wallets from generic key-value records to a dedicated 'transactions' relational table. Each transaction field is stored in its own column, allowing the wallet to load records ordered by position. It also introduces automatic schema upgrade and downgrade tracking using client feature flags.",
  "problem": "The wallet treats SQLite as a simple key-value store, forcing complex composite serialization and resulting in arbitrary record loading order. This out-of-order load complicates wallet logic that relies on transaction sequences, such as tracking spent outputs.",

  "card": "This PR begins shifting Bitcoin Core SQLite wallets away from flat key-value storage toward relational tables, starting with a dedicated transactions table. Storing transactions with explicit columns allows querying by wallet assignment order, simplifying downstream logic for transaction state and output tracking. Downstream work such as tracking no-longer-spendable TXOs in #27865 explicitly benefits from this structure. Review is currently blocked by failing CI runs and dependencies on #32895 and #33033, though initial concept feedback has been strongly supportive."
