   `UpdateApiKeyCommand(IsEnabled)` → `SetEnabledAsync`; new set-scopes path → `SetScopesAsync`; `DeleteApiKeyCommand` →

+### Discovered architecture (CentralUI Explore, 2026-06-02) — expands C/D/E
+Two facts the original A–E spec missed:
+1. **CentralUI bypasses the ManagementActor.** `Components/Pages/Admin/ApiKeys.razor`, `ApiKeyForm.razor`, and
+   `Components/Pages/Design/ApiMethodForm.razor` call `IInboundApiRepository` (SQL Server EF) **directly** — they do NOT
+   send the `CreateApiKeyCommand`/etc. management messages. So there are **two** management entry points to rewire
+   (CLI→ManagementActor uses the messages; CentralUI→repository uses the entities). Decoupling: introduce one app-side
+   **`IInboundApiKeyAdmin` seam** over the library `ApiKeyAdminCommands`, and route BOTH CLI and CentralUI through it
+   (DRY + single audit path). The message-contract change (int→string) touches only CLI+ManagementActor; the
+   entity/repository change (`ApiKey.Id`, `ApiMethod.ApprovedApiKeyIds`) touches CentralUI + TransportExport.
+2. **TransportExport couples API keys + methods into config export/import** (`Components/Pages/Design/TransportExport.razor`
+   + `.razor.cs`, `HashSet<int>` selections, `ExportSelection`). With keys now in the library SQLite store (per-env pepper,
+   secret-once), a key can't be exported/re-imported usefully. **Decision (user, 2026-06-02): EXCLUDE inbound API keys from
+   transport — export API methods only; keys are re-created + method-scopes re-granted per environment.**
+
+CentralUI blast radius (string keyId + scopes replace int Id + ApprovedApiKeyIds CSV): `Admin/ApiKeys.razor`,
+`Admin/ApiKeyForm.razor`, `Design/ApiMethodForm.razor` (approved-keys ↔ key-scopes), `Design/TransportExport.razor(.cs)`,
+`Design/ExternalSystems.razor` (uses method `int` id — methods STAY int in SQL Server, so unaffected for keys),
+`Dashboard.razor` (key count), test `Admin/ApiKeyFormAuditDrillinTests.cs`.
+
+### C/D/E decomposition — 5 reviewed green sub-commits (user: "coordinated multi-commit now", 2026-06-02)
+- **C1** — re-pin ScadaBridge Auth 0.1.2→0.1.3; add app-side `IInboundApiKeyAdmin` seam (string-keyId model:
+  Create(name,methods)→(keyId,token) / List / SetEnabled / SetMethods / Delete[=revoke+delete] / GetMethodsForKey /
+  GetKeysForMethod) over the library facade; register `ApiKeyAdminCommands` + the seam in Host **and** CentralUI DI; seam
+  unit tests. **Purely additive — build green.**
+- **C2** — Commons `Messages/Management/SecurityCommands.cs` contracts int→string keyId + add `Methods` + new
+  `SetApiKeyMethodsCommand`; rewire ManagementActor handlers + CLI `security api-key` onto the seam; update ManagementActor
+  tests. (CentralUI unaffected — it doesn't use these messages.)
+- **C3** — CentralUI `ApiKeys.razor`/`ApiKeyForm.razor`/`ApiMethodForm.razor` (+ Dashboard count) off `IInboundApiRepository`-
+  for-keys onto the seam; string keyId; method-scope editing replaces `ApprovedApiKeyIds`; update bUnit test. (Methods stay
+  in SQL Server; just stop using the `ApprovedApiKeyIds` column — dropped in C5.)
+- **C4** — TransportExport: remove API-key selection/export (methods-only); drop key `HashSet<int>` + `ExportSelection` keys;
+  tests.
+- **C5 (=E)** — retire SQL Server `ApiKey` entity + DbContext reg + `IInboundApiRepository` key methods +
+  `GetApprovedKeysForMethodAsync`; drop `ApiMethod.ApprovedApiKeyIds`; EF migration (drop ApiKeys table + column); delete
+  residual `ApiKeyValidator`/`ApiKeyHasher`; runbook + CHANGELOG (breaking: re-issue keys, `X-API-Key`→`Authorization: Bearer`);
+  full build+test sweep.
