@@ -72,4 +72,7 @@ Delivery: `feat/adopt-zb-audit` (stacked on auth), local-only. Each stage = one
 - **✅ C4 DONE** `946d3e2` + fix `1737d15` (spec ✅, code ✅; independently re-verified diff scope = writer+tests only, build 0/0, AuditLog 249/1-preexisting). Site SQLite → `audit_event` (canonical) + `audit_forward_state` sidecar; forwarding marks/reads on the sidecar via JOIN; `IsCachedKind`={CachedSubmit,ApiCallCached,DbWriteCached,CachedResolve} precomputed drain split; old `AuditLog` table dropped (ephemeral reset). Fix: `PRAGMA foreign_keys=ON` + `MarkForwarded` no-demote guard.
 - **✅ C5 DONE** `68a6bd1` (spec ✅, code ✅; a LIVE SQL Server was available so the migration + SWITCH were fully exercised — independently re-verified build 0/0 + ConfigurationDatabase 248/248). Central `dbo.AuditLog` collapsed to 10 canonical cols + 6 computed cols (5 PERSISTED + `IngestedAtUtc` non-persisted) on the preserved `ps_AuditLog_Month` scheme; `CollapseAuditLogToCanonical` new-table-and-copy migration (`FOR JSON PATH` projection, byte-verified round-trip; Down = documented one-way); repo writes/reads canonical directly; `SwitchOutPartition` staging matches the computed-col defs; append-only roles re-granted. C3 central shim retired. Forced deviations (all sound): IngestedAtUtc non-persisted, execution-id indexes unfiltered, provider-aware `OnModelCreating` strips JSON_VALUE for SQLite. Deferred to C7: a dedicated migration-projection test + the stale `CreatesFiveNamedIndexes` test name.
 - **✅ C6 SUBSUMED** (no commit) — reporting/UI/export/CLI retarget was already completed by the C3 record-swap (`AuditEventView`/`AuditExportRow` shims decode every domain field from `DetailsJson`) + the C5 repo-query retarget. Read-only explorer verdict: all consumer surfaces canonical-complete; the only flagged items (ExecutionId/ParentExecutionId not in CSV; SourceNodes not parsed in export `ParseFilter`) are PRE-rearch omissions, not regressions. CentralUI 595/595, ManagementService 125/125 confirm.
-- **⏳ C7 IN PROGRESS** — perf re-baseline (redactor now parses DetailsJson) + deferred C5 migration-projection test + index-test-name fix + dead-`<see cref>` cleanup; final full-suite green.
+- **✅ C7 DONE** `635461c` + doc-fix `bc0e5bf` (review ✅; independently re-verified build 0/0, PerformanceTests 10/10, ConfigurationDatabase 251/251 incl. the 3 new migration-projection tests PASSING on live MSSQL, zero dead crefs). Perf hot-path re-baselined (canonical JSON redactor measured ~14µs/2µs — faster than the old typed walk; budgets 200/30/5µs + fast-path `Assert.Same`); `CollapseAuditLogToCanonicalMigrationTests` (seed→migrate→assert Action/Category/Outcome/Actor-null/DetailsJson-round-trip + 5 persisted computed cols); index test → `CreatesNineNamedIndexes`; 26 dead-`<see cref>` across 13 files cleaned; doc-fix corrected the "six persisted" wording (5 persisted + IngestedAtUtc non-persisted).

+## ✅ TASK 2.5 COMPLETE — ScadaBridge audit FULL re-architecture to pure 9-col canonical (2026-06-02)
+All of C1–C7 done, each spec+code reviewed, on `feat/adopt-zb-audit` (local-only, never pushed). ScadaBridge's audit subsystem now: the canonical `ZB.MOM.WW.Audit.AuditEvent` record everywhere (domain fields in `DetailsJson` via the deterministic `AuditDetailsCodec`); the library `IAuditRedactor`/`AuditOutcome` consumed; site SQLite = `audit_event` (canonical) + `audit_forward_state` sidecar (forwarding decoupled, `IsCachedKind` drain split); central `dbo.AuditLog` collapsed to 10 canonical cols + persisted computed cols on the preserved partition scheme (`CollapseAuditLogToCanonical` migration, MSSQL-verified); UI/export/CLI canonical-complete via `AuditEventView`/`AuditExportRow`. The gRPC proto was intentionally left unchanged (mapper-internal projection). This was the program's single largest task.
