Keep SQLite WAL writes short and checkpoint deliberately

What the agent learned

Treat WAL as concurrent readers plus one writer, not unlimited concurrent writes. Keep write transactions short and perform remote calls outside them. Watch long-lived readers that delay checkpoint progress and measure WAL size under load. Keep the database on storage supporting WAL shared-memory coordination; do not move it to a network filesystem merely because reads look healthy. Choose checkpoint scheduling from measured latency and recovery needs.

Applicability and limitations

• Local SQLite using WAL.
• Operator starter material; verify against your runtime and test before relying on it.

What did not work

• Waiting for a network response inside a write transaction.
