A verified audit of all ~90 plan documents (2026-08-01) found ~30 .tasks.json
trackers and several plan headers still reporting 'pending'/'draft' for work
fully merged to main. Sync them so future audits don't re-litigate closed work:
- Flip ~380 stale task statuses to completed across March/May/June/July
trackers (audit-log series, milestones M5-M10, playwright waves, stillpending,
LocalDb, ClusterClient->gRPC DoD rows, and more), each verified against
code/git evidence before flipping.
- Annotate obsolete-not-done rows: ClusterClient CLI transport (never built,
HTTP shipped), TreeView Areas/Instances pages (replaced by Topology),
template-tree drag-drop (dropped for M9 menu reorder), otopcua item C
(premise superseded by #17).
- Flip stale headers: aggregated-live-alarm + kpi-rollups 'Draft not executed'
-> Delivered 2026-07-10; otopcua cutover-scope SCOPING -> DECIDED;
scadabridge-rename -> Implemented; LocalDb phase1/2 status strings ->
merged 28ca04d7.
- Fix doc drift: T9/T10 'deferred' -> shipped as SMS (Teams dropped); waitfor
sandbox follow-up shipped; followups #52/#53/#54/#162/#207 resolved; purge
TODO closed by PendingDeploymentPurgeActor; live-gate pre-existing failures
#28/#29/#31 fixed; auto-down boot-alone residual superseded by self-first
seeds; supersession banners on keep-oldest SBR + ClusterClient-era designs;
requirements-traceability 'Pending' clarified as frozen plan-generation
status.
Deliberately left pending (genuinely open, tracked in the pending-work list):
opcua-tag-browser task 19 (live smoke), ipsen tasks 7-8 (vd03 verification),
selfform task 7 (vd03 overlay, user-held), live-gate observation 1
(external-system delete orphan bug), otopcua item A + maxDepth calibration.

Implementation Questions
Purpose: Track questions and ambiguities discovered during plan generation that require follow-up before or during implementation.
Open Questions
Phase 7: Integrations
| # | Question | Context | Impact | Status |
|---|---|---|---|---|
| Q12 | What Microsoft 365 tenant/app registration is available for SMTP OAuth2 testing? | Affects Notification Service OAuth2 implementation. | Phase 7. | Deferred — won't be known during development. Implement against Basic Auth first; OAuth2 tested when tenant available. |
Resolved Questions
| # | Question | Resolution | Date |
|---|---|---|---|
| Q1 | What .NET version should we target? | .NET 10 LTS (released November 2025, supported through 2028). | 2026-03-16 |
| Q2 | What Akka.NET version? | Latest stable 1.5.x (currently 1.5.62). | 2026-03-16 |
| Q3 | Monorepo or separate repos? | Single monorepo with SLNX solution file (.slnx, the new XML-based format default in .NET 10). |
2026-03-16 |
| Q4 | What CI/CD platform? | None for now. No CI/CD pipeline. | 2026-03-16 |
| Q5 | What LDAP server for dev/test? | GLAuth (lightweight LDAP) in Docker. See infra/glauth/config.toml and docs/test_infra/test_infra_ldap.md. |
2026-03-16 |
| Q6 | What MS SQL version and hosting? | SQL Server 2022 Developer Edition in Docker. See infra/docker-compose.yml and docs/test_infra/test_infra_db.md. |
2026-03-16 |
| Q7 | JWT signing key storage? | appsettings.json (per environment). |
2026-03-16 |
| Q8 | OPC UA server for dev/test? | Azure IoT OPC PLC simulator in Docker. See infra/opcua/nodes.json and docs/test_infra/test_infra_opcua.md. |
2026-03-16 |
| Q10 | Target site hardware? | Windows Server 2022, 24 GB RAM, 1 TB drive, 16-core Xeon. | 2026-03-16 |
| Q11 | Are there specific external systems (MES, recipe manager) to integrate with for initial testing? | REST API test server (infra/restapi/) provides simulated external endpoints for External System Gateway and Inbound API testing. No real MES/recipe system needed for initial phases. |
2026-03-16 |
| Q15 | Should the Machine Data Database schema be designed in this project, or is it out of scope? | Out of scope — Machine Data Database is a pre-existing database at customer sites. Test infra seeds sample tables/data in infra/mssql/machinedata_seed.sql. |
2026-03-16 |
| Q13 | Who is the development team? | Solo developer with extensive Akka.NET experience and full availability. No parallelization constraints — phases are sequential. | 2026-03-16 |
| Q14 | Is there an existing deployment target environment for early pilot testing? | Yes — developer can test directly. No separate pilot environment needed. | 2026-03-16 |
| Q16 | Should Result<T> use a OneOf-style library or be hand-rolled? |
Hand-rolled to maintain zero-dependency constraint (REQ-COM-7). | 2026-03-16 |
| Q17 | Should entity POCO properties be required (init-only) or settable? | { get; set; } for EF compatibility, with constructor invariants for required fields. |
2026-03-16 |
| Q18 | What QualityCode values should the protocol abstraction define? |
Good, Bad, Uncertain as the minimal set, with room to extend. | 2026-03-16 |
| Q19 | Should IDataConnection be IAsyncDisposable for connection cleanup? |
Yes — add IAsyncDisposable to support proper cleanup in DCL connection actors. |
2026-03-16 |
| Q-P1-1 | Data Protection keys — DB or shared filesystem? | DB storage (EF Core Data Protection key store). More portable than shared filesystem mount. | 2026-03-16 |
| Q-P2-1 | What hashing algorithm for revision hashes? | SHA-256. | 2026-03-16 |
| Q-P2-2 | What serialization format for the deployment package contract? | JSON for debuggability. Can add binary format later if needed. | 2026-03-16 |
| Q-P2-3 | How should script pre-compilation handle references to runtime APIs? | Compile against a stub ScriptApi assembly at central. Site uses real implementation. | 2026-03-16 |
| Q-P2-4 | Semantic validation for CallShared — current library or deployed version? | Validate against current library; re-validate on deploy. | 2026-03-16 |
| Q-P3A-1 | Staggered Instance Actor startup batch size/delay? | Default 20 actors per batch, 100ms delay. Make configurable. Tune during Phase 3B/8. | 2026-03-16 |
| Q-P3A-2 | Single SQLite file or separate files per concern? | Single file with separate tables. Simpler transaction management. | 2026-03-16 |
| Q-P3A-3 | Akka.Persistence or direct SQLite for Deployment Manager singleton? | Direct SQLite. Recovery is full read-all-configs-and-rebuild, not event replay. | 2026-03-16 |
| Q-P3B-1 | Blocking I/O dispatcher config for Script Execution Actors? | Use Akka.NET default blocking-io-dispatcher config. Tune during Phase 8 performance testing. | 2026-03-16 |
| Q-P3B-3 | Rate of Change alarm evaluation time window? | Configurable window, default per-second rate. Document in alarm definition schema. | 2026-03-16 |
| Q-P3B-4 | Health report sequence number across failover? | Resolved in design — offline detection handles the reset naturally. Central accepts lower seq after site goes offline/online. | 2026-03-16 |
| Q-P3C-1 | S&F retry timers on failover — reset or continue? | Continue from last_attempt_at to avoid burst retries. |
2026-03-16 |
| Q-P3C-2 | Max parked messages per remote query? | Paginated, 100 per page, consistent with Site Event Logging pattern. | 2026-03-16 |
| Q-P3C-3 | Per-instance operation lock — in-memory or persisted? | In-memory. Released on failover. Site state query resolves any ambiguity. | 2026-03-16 |
| Q-P4-1 | API key values — auto-generated or user-provided? | Auto-generated with copy-to-clipboard. User can regenerate. | 2026-03-16 |
| Q-P4-2 | Health dashboard refresh interval? | Updates on every report arrival (server push). No UI-side polling. Superseded (2026-08-01): as shipped, the Health dashboard refreshes on a 10s UI polling timer — the server-push answer recorded here was not the implemented behavior. | 2026-03-16 |
| Q-P4-3 | Area deletion — cascade or bottom-up? | Cascade delete child areas if no instances are assigned to any area in the subtree. | 2026-03-16 |
