Alarm Summary is now live-cache-driven via a transient per-site central live alarm cache (ISiteAlarmLiveCache) fed by a site-wide, alarm-only SubscribeSite gRPC stream (seed-then-stream), with the 15s poll retained as fallback + NotReporting authority. No persisted central alarm store ([PERM]). Updated Component-CentralUI, Component-Communication (new §6.1 + SubscribeSite RPC), M7 design (T13 delivered note), native-alarms [PERM] note, stillpending follow-up note, CLAUDE.md, and moved register row #10 to Resolved (left #22 in place for the sibling branch).

# Deferred-Work Register (established 2026-07-08, from architecture review 08)
|
||
|
||
Single tracked list of consciously-deferred work. Rules: every deferral gets a row
|
||
(rationale + revisit trigger); fix-now items reference the archreview plan that owns
|
||
them and are removed from this table when that plan's task lands.
|
||
|
||
## Fix-now (owned by archreview plans)
|
||
| # | Item | Owner |
|
||
|---|------|-------|
|
||
| 1 | Transport: Area membership doesn't travel in bundles (EntitySerializer.cs:251,518) | PLAN-05 |
|
||
| 2 | CLI.Tests not in slnx | PLAN-08 Task 1 |
|
||
| 3 | AuditLog reconciliation dials site NodeA only (SiteEnumerator.cs:32,64) | PLAN-04 |
|
||
| 4 | Options validation missing on ~12 components | PLAN-08 Tasks 2–5 |
|
||
| 5 | SmsConfiguration.MaxRetryCount stored but not honored | PLAN-06 |
|
||
| 6 | Role-check case-sensitivity asymmetry (ManagementActor.cs:1910) | PLAN-07 |
|
||
| 23 | Vestigial site-side notification-list surface | PLAN-08 Task 6 |
|
||
|
||
## Deferred (with rationale + revisit trigger)
|
||
| # | Item | Where noted | Rationale for deferral | Revisit trigger |
|
||
|---|------|-------------|------------------------|-----------------|
|
||
| 8 | Hash-chain tamper evidence (T1); CLI verify-chain is a no-op stub | audit-log roadmap :12 | v1.x by locked decision; append-only DB roles are the control | Compliance requirement for cryptographic tamper evidence |
|
||
| 9 | Parquet audit archival (T2); endpoint returns 501 | AuditEndpoints.cs:204 | v1.x; 501 + CLI messaging are honest | AuditLog partition volume nears retention ceiling |
|
||
| 11 | Central-persisted OPC UA cert-trust audit | m7 follow-ups | Broadcast-to-both-nodes covers HA | Governance/audit requirement for trust decisions |
|
||
| 12 | Native-alarm-source-override CSV import — **Central UI `InstanceConfigure` upload affordance only** (CLI + Management API + parser shipped 2026-07-10, see Resolved) | m7 follow-ups | CLI/API path closes the operator parity gap; the Blazor upload button is polish | First request to bulk-import native sources from the UI rather than the CLI |
|
||
| 17 | Unified notifications+site-calls outbox page | stillpending :118 | Explicit M9 decision to keep two pages | Operator confusion reports |
|
||
| 18 | Folder drag-drop | same, [PERM] | Permanently closed; menu reorder shipped | — (closed) |
|
||
| 19 | Bundle signing / cluster-to-cluster pull / differential bundles | transport-design :402 | v1 manifest hash + AES-GCM held sufficient | Non-repudiation requirement across orgs |
|
||
| 22 | KPI history hourly rollups | Component-KpiHistory.md | YAGNI; 90-day retention bounds table | KpiSample query latency on dashboards |
|
||
|
||
## Resolved (verified against the code 2026-07-10)
|
||
Rows removed from the Deferred table above once confirmed shipped. Kept here for traceability.
|
||
|
||
| # | Item | Resolution |
|
||
|---|------|-----------|
|
||
| 10 | Aggregated live alarm stream for Alarm Summary | Shipped 2026-07-10 (`docs/plans/2026-07-10-aggregated-live-alarm-stream-plan.md`): a **transient, in-memory** per-site central live alarm cache (`ISiteAlarmLiveCache`/`SiteAlarmLiveCacheService` + per-site `SiteAlarmAggregatorActor`) fed by a new site-wide, alarm-only `SubscribeSite` gRPC stream (`SiteStreamManager.SubscribeSiteAlarms`), seed-then-stream with dedup + NodeA↔NodeB re-seed + periodic reconcile. Alarm Summary is now live-cache-driven (`AlarmSummaryService.BuildFromLiveAlarms`) with the 15s poll retained as fallback + `NotReporting` authority. Honors the `[PERM]` no-central-store rule — nothing persisted (no EF table/migration). Options on `CommunicationOptions` (eagerly validated) + two `ScadaBridgeTelemetry` signals. |
|
||
| 7 | SecuredWrite audit rows leave SourceNode NULL | Resolved (PLAN-07): `ManagementActor.EmitSecuredWriteAuditAsync` routes through `ICentralAuditWriter`, which stamps `SourceNode` (`central-a`/`central-b`) from `INodeIdentityProvider`. |
|
||
| 12 (CLI/API) | Native-alarm-source-override CSV import | Shipped 2026-07-10: shared `CsvLineSplitter`, `NativeAlarmSourceOverrideCsvParser`, bulk all-or-nothing `SetInstanceNativeAlarmSourceOverridesCommand` + ManagementActor handler (Deployer-gated), CLI `instance native-alarm-source import --file`, parser/CLI/handler tests. **UI upload affordance still pending — see row 12 above.** |
|
||
| 13 | WaitForAttribute quality-gated ("Good"-only) mode | Already implemented (Commons `WaitForAttribute.RequireGoodQuality`, enforced in `InstanceActor`, threaded through `ScriptRuntimeContext`, tested in `InstanceActorWaitForAttributeTests`). Stale "planned enhancement" doc line corrected 2026-07-10. |
|
||
| 14 | WaitForAttribute in Test-Run sandbox | Shipped 2026-07-10 (full fidelity): sandbox `Attributes.WaitAsync`/`WaitForAsync` (value-equality) route to the bound instance via `ISandboxInstanceGateway.WaitForAttributeAsync` → the existing `CommunicationService.RouteToWaitForAttributeAsync` cross-site route. Additive `RouteToWaitForAttributeRequest.RequireGoodQuality` (honored by the site handler) makes quality-gated waits route too. **Predicate-form waits stay unsupported** (an in-process lambda can't be routed) and throw a labelled `ScriptSandboxException`. Tests: sandbox accessor routing (CentralUI), site-handler quality-flag threading (SiteRuntime). |
|
||
| 15 | BrowseNext final-page signal not surfaced | Already surfaced (M7 browse work): `RealOpcUaClient` sets `Truncated=false`/`ContinuationToken=null` on the last page; `BrowseNodeResult` carries both; `TreeRow.razor` renders "Load more" only when a continuation token remains — no wasted BrowseNext. |
|
||
| 16 | StubOpcUaClient throws on browse | Already resolved: `StubOpcUaClient` supports browse + address-space search, covered by `StubOpcUaClientBrowseTests`/`StubOpcUaClientSearchTests`. |
|
||
| 20 | Deployment EXPIRED-row purge | Already resolved (PLAN-04): `PendingDeploymentPurgeActor` central singleton (spawned in `AkkaHostedService`) ticks `IDeploymentManagerRepository.PurgeExpiredPendingDeploymentsAsync` every `CommunicationOptions.PendingDeploymentPurgeInterval` (default 1h), options-validated, tested. |
|
||
| 21 | SiteAuditBacklogReporter threshold consolidation | Shipped 2026-07-10: `SqliteAuditWriterOptions.BacklogPollIntervalSeconds` (default 30) now drives the reporter's poll cadence; explicit ctor override still wins (tests), non-positive falls back to the 30 s default. Cadence tests added; stale "hard-code / follow-up" class-doc corrected. |

||
## New deferrals from review 08 (this plan)
|
||
| Item | Rationale | Revisit trigger |
|
||
|------|-----------|-----------------|
|
||
| Communication → HealthMonitoring layering (ICentralHealthAggregator consumed by CentralCommunicationActor.cs:351) | Moving the interface + SiteHealthState to Commons ripples across 5 projects for a cosmetic inversion | Next breaking change to ICentralHealthAggregator |
|
||
| docs/components reference docs for ScriptAnalysis, KpiHistory, DelmiaNotifier | Reference docs are substantial (StyleGuide-conformant); README claim scoped instead (PLAN-08 Task 10) | Next doc-writing session touching those components |
|
||
| Test-coverage backfill: SiteCallAudit.Tests (31 tests/1.6k LOC), DeploymentManager.Tests | No defect identified; coverage partly lives in ManagementService/Host/Integration suites | First regression escaping either component |
|
||
| Failover-timing + broader perf envelope (S&F drain rate, per-subscriber backpressure) | Needs PLAN-01 two-node rig; placeholder harness shipped (PLAN-08 Task 8) | PLAN-01 rig landing |
