PLAN-04 Task 24. Component-Commons: AuditChannel gains SecuredWrite (5), AuditKind full 15-value list (+SecuredWrite*/ReconciliationAbandoned), NotificationType Email/Sms (Teams evaluated+dropped), AuditLogRow persistence-only-projection deviation note. ConfigDB: Type discriminator Email/Sms, data-layer conventions (UTC DateTime + Utc converter, MSSQL- only repos/fixtures, AuditLog clustered-key + P3/P4/P6 tracked follow-ups). SiteCallAudit: schema table rewritten to shipped columns (Channel/Target/AuditStatus-Status/SourceNode/ HttpStatus/IngestedAtUtc; no Kind/TargetSummary/provenance) + stored-vs-tracking-view note. AuditLog: per-channel retention config lists all 5 channels incl SecuredWrite. Also fixed two stale 'Teams planned' refs surfaced by the verification grep (HighLevelReqs, CentralUI).
