This isn't just a version-number check: powersync-service PR #810 (source_table_options parsing) and #811 (MongoDB replication query provider) are both still open, and #811 says outright "No actual filtering—this only defines the extension point an external module can build on." The paired self-host-demo PR #67 for this same feature is also still open. There's no merged implementation anywhere to verify the operators, EJSON handling, or behavior described below against — hold publication until these merge (or a release note confirms the feature shipped).

| The [self-hosted MongoDB pre-filtering demo](https://github.com/powersync-ja/self-host-demo/tree/main/demos/nodejs-mongodb-prefiltering) filters archived lists and todos. It includes source indexes, seed data, and a stream writer so you can compare source counts with the client's synced data. |

This demo isn't on main yet — it's still in open PR powersync-ja/self-host-demo#67 ("feat: MongoDB Replication Pre-filtering demo"). The link currently 404s, which matches this PR's failing "Check External Links" CI job. Don't publish this link until #67 merges.
This adds documentation for the Team/Enterprise MongoDB Replication Pre-filtering feature.
