Rows ingested before M5.6 shipped have `SourceNode IS NULL` because +the value was not populated until the feature landed. A one-time CLI command sets +these to a configurable sentinel: + +``` +scadabridge audit backfill-source-node --before [--sentinel unknown] [--batch 5000] +``` + +The default sentinel is `"unknown"`. The true node-of-origin for pre-feature rows +is **unknowable** retroactively — the emitting node is long gone from the telemetry +pipeline. The sentinel makes that explicit rather than leaving the column NULL +(which the Audit Log UI's Node filter already treats as "unresolved", but which +an operator might mistake for a data-quality bug). + +The backfill runs via `POST /api/audit/backfill-source-node` (Admin role required) +on the maintenance/purge path, NOT the append-only `scadabridge_audit_writer` role. +It is idempotent and can be re-run safely. + +### `ExecutionId` and `ParentExecutionId` — cannot be backfilled + +`ExecutionId` and `ParentExecutionId` are **PERSISTED COMPUTED columns** derived +from `DetailsJson`. They were introduced in the same feature window as the column +itself but their value comes from the JSON payload that was written at ingest time. + +The AuditLog append-only invariant **forbids mutating `DetailsJson`** — rows may +only be inserted, never updated. Because backfilling the computed values would +require rewriting the underlying `DetailsJson`, it is impossible under the +append-only contract. Pre-feature rows carry `NULL` in both columns permanently. + +This is a documented limitation, not a defect. The NULL values are visible in the +Audit Log UI's execution-tree drilldown (rows with no `ExecutionId` appear as +orphaned entries) and in the CLI's `audit tree` output. + ## Dependencies - **[Commons (#16)](Component-Commons.md)** — `AuditEvent`, `IAuditWriter` / diff --git a/src/ZB.MOM.WW.ScadaBridge.CLI/Commands/AuditBackfillHelpers.cs b/src/ZB.MOM.WW.ScadaBridge.CLI/Commands/AuditBackfillHelpers.cs new file mode 100644 index 00000000..e59e21c1 --- /dev/null +++ b/src/ZB.MOM.WW.ScadaBridge.CLI/Commands/AuditBackfillHelpers.cs @@ -0,0 +1,113 @@ +using System.Text; +using System.Text.Json; + +namespace ZB.MOM.WW.ScadaBridge.CLI.Commands; + +/// +/// Arguments for an audit backfill-source-node invocation. +/// +public sealed class AuditBackfillSourceNodeArgs +{ + /// + /// Value written into SourceNode for NULL rows (default "unknown"). + /// + public string Sentinel { get; set; } = "unknown"; + + /// + /// Only rows with OccurredAtUtc strictly before this UTC datetime are + /// eligible.
