### SQLite Production Tuning
**Status:** Complete
- [x] Concurrency tests proving WAL read scaling, IMMEDIATE vs DEFERRED transaction behaviour
- [x] BenchRepo for isolated testing against temp DB files (no Sandbox dependency)
- [x] `mix bench.sqlite` task with `--prod`, `--scale`, `--pool-size`, `--busy-timeout` options
- [x] PRAGMA tuning across dev/test/prod: `default_transaction_mode: :immediate`, `journal_size_limit: 64MB`, `custom_pragmas: [mmap_size: 128MB]`
- [x] Benchmarks confirmed: IMMEDIATE mode eliminates transaction upgrade BUSY errors (0% vs 73-80% failure rate under contention), prod mode 5-12x faster than dev, 300 concurrent mixed requests with zero errors
- [x] 898 tests total (6 correctness + 3 benchmarks excluded by default)
