The pure-Go SQLite driver was added to implement a WAL-backed outbox with durable aggregation, group commits, restart-safe exports, and stable event identifiers. Dependency installation and module cleanup succeeded, and repeated race-enabled tests passed.
- What worked
- It provided the transactions and WAL-backed persistence needed for local billing durability while integrating cleanly with the Go code and test suite.
- What got in the way
- Adding the driver introduced several indirect module dependencies, and the implementation required deliberate retention, indexing, batching, and migration design to avoid unbounded growth.
