…, fix test status type - Register the implicit single source with id "legacy" so its leader-lock key matches the id the admin status route probes; otherwise leadership always reads false in the non-split config. - Guard the shutdown-path client.stop() fan-out against re-firing per incoming transaction and add a catch so rejections don't surface as unhandled. - Use the TaskRunStatus type alias (not the const value) for status annotations in the dual-source dedup tests.

…fore replacing it The legacy-only instance constructed at boot opens a replication client (Redis + Redlock) eagerly; when the split gate resolves to a multi-source service it was replaced without cleanup, leaking one Redis connection per split-enabled boot. shutdown() the bootstrap instance first (idempotent, safe on the never-started instance).

What
Extends the ClickHouse runs-replication service to fan in from multiple Postgres sources (the control-plane DB and the run-ops DB) instead of a single source, plus the admin operations to run and observe it.
services/runsReplicationService.server.ts, newrunsReplicationInstance.server.ts,runsReplicationGlobal.server.ts): factors the replication service into per-source instances and a coordinator so a single ClickHouse target is fed from more than one Postgres source.routes/admin.api.v1.runs-replication.status.ts,admin.api.v1.runs-replication.backfill.ts,v3/services/adminWorker.server.ts): adds a status endpoint reporting per-source replication state and updates the backfill entrypoint for the multi-source shape.Why
PR7 of the run-ops split stack, and the final piece: once run state can live in a separate run-ops DB (earlier PRs), the analytics replication into ClickHouse has to consume both sources so runs remain queryable regardless of residency. Behavior-changing for the replication service internals; the ClickHouse-facing output is unchanged (still one runs stream), and single-source operation is preserved when the split is not enabled.
Tests
New vitest coverage:
runsReplicationInstance.test.ts(per-source instance behavior) andrunsReplicationService.part8/part9suites exercising the multi-source coordinator. Testcontainers-backed (ClickHouse + Postgres); no mocks.Notes
Draft, stacked on #4118 (
runops/pr06-write-path). Review that first; this diff is against it.Server-change / changeset note to be added at stack-assembly time.
