Task 12 + Task 13. No production behaviour change in either. Task 12: DeploymentManagerActor.HandleDeployArtifacts already purges notification_lists and smtp_configurations on every artifact apply, but nothing pinned the actor's CALL to it — ArtifactStorageTests covers the storage method only. Task 15 deletes SiteReplicationActor's copy, making this the sole remaining call site, and Task 16 edits this actor's wiring; dropping the call would leave plaintext SMTP passwords on disk with every suite still green. Verified red-first by commenting the call out: the pin fails with that message. Task 13: StoreDeployedConfigIfNewerAsync STAYS. Re-verified both callers — SiteReplicationActor:375 (dies at Task 15) and SiteReconciliationActor:166 (survives). Reconciliation is a per-node startup self-heal against central whose fetch races real deploys, so the deployed_at guard still does real work there. Doc comment rewritten to say so, and to warn against porting the guard onto the replication path where it would fight the HLC rather than help it. Also corrected a stale 'guarded standby write' section header in the tests. Re-ran the Task 13 step 2 scope check: ConfigFetchRetryCount's only production reader remains SiteReplicationActor:157, so its option + validator rule stay until Task 17, after Task 15 deletes the actor. Verified: build 0 warnings; SiteRuntime 533, Host 329, StoreAndForward 153, LocalDb integration 16 — all pass. Claude-Session: https://claude.ai/code/session_01BL2Vu1ESDQ9SCN4gVKkdts
