 | 108 | ~~**Inbound API keys are a PER-NODE SQLite store — a central failover invalidates every inbound client's key**~~ **RESOLVED 2026-09-02 — `ZB.MOM.WW.Auth` 0.3.0 (new `ZB.MOM.WW.Auth.ApiKeys.SqlServer` package) + ScadaBridge `ScadaBridge:InboundApi:ApiKeyStore:Provider=SqlServer`.** A central pair now shares one row set: both nodes' key stores, admin stores, and audit stores point at the same `zbauth` schema in the configuration database (connection string defaults to `ScadaBridge:Database:ConfigurationDb` — never a `${secret:}` reference, to avoid a circular dependency on the SQL-backed secrets store), so create/revoke/rotate/scope changes are cluster-wide immediately instead of per-node. Each node's existing SQLite file is imported once at boot (insert-where-absent, so both nodes importing is safe and the result is the union) and renamed `*.imported`. `Provider` defaults to `Sqlite` (unchanged behavior for single-node installs, MxAccessGateway, HistorianGateway); a clustered Central left on `Sqlite` now gets a boot-time `StartupValidator` Warning naming this design instead of silently keeping the gap. Both docker rigs (`docker/`, `docker-env2/`) run `Provider=SqlServer` on both centrals; `docker/sync-inbound-api-keys.sh` is deleted, superseded by the shared store. Rig proof 2026-09-03 (`docker/`, both centrals redeployed on `Provider=SqlServer`): both nodes imported their SQLite file at the same second with no PK race — central-a `1 key / 264 audit rows inserted`, central-b `0 / 26 inserted, 1 / 264 already present` (the union), files renamed `*.imported`; a key minted via `:9001` answered `200` via `:9002`, `--enabled false` via `:9001` made both nodes answer `401` and `:9002`'s own list showed `enabled=False`, re-enable via `:9002` restored `200` on `:9001`, delete via `:9002` made `:9001` answer `401`; `verify-delmia-notifier.sh` with a freshly minted key and NO file copy: A/B/E/F `YES`, C/G `NO`, active-central `docker kill` takeover **28 s**, rejoin as standby in 2 s. `docker-env2` (second pair, `ScadaBridgeConfig2`): both centrals booted, `zbauth` v1 created, empty files imported. QA (`vq03`/`vq04`) and prod (`vd03`) still run `Provider=Sqlite` — their move is a planned deployment record (`docs/deployment/deployment-records/2026-09-XX-zb-servers-inbound-key-store.md`), not yet applied. Design: `docs/plans/2026-09-02-inbound-api-key-shared-store-design.md`. Original: | `docs/api-specs/Delmia-Recipe-Download-API.md` §8; `docker/sync-inbound-api-keys.sh` header | Fix is an architecture decision, not a patch: move the store to the shared SQL Server (as Secrets 0.5.0 did for its central store) or replicate the file; either way revocation must become cluster-wide. Needs the `ZB.MOM.WW.Auth.ApiKeys` library (scadaproj), not just this repo. | Before any 2-node central goes live with inbound API clients; before the next arch-review wave. |
 | 109 | **`ZB.MOM.WW.Secrets.Replicator.SqlServer`'s store migrator retries its DDL with a flat `100 * attempt` backoff and no jitter — a latent concurrent-boot flake, open in Secrets** *(Low)*. Porting that migrator's retry loop verbatim for the Auth 0.3.0 SQL Server API-key store (register row 108) reproduced an intermittent exhaustion — about once in sixty 8-way concurrent-boot trials the five flat-backoff retries ran out before a DDL/lock conflict cleared; adding jitter to the Auth port's backoff took it to 0 failures in 180 trials. Secrets' own migrator has no concurrent-migrate test, so the same defect is presumed still open there — it just hasn't been exercised at 8-way concurrency, and a ScadaBridge central pair is only ever 2-way, so this is unlikely to bite in practice. | Found 2026-09-02 while implementing `docs/plans/2026-09-02-inbound-api-key-shared-store.md` (Auth 0.3.0 `SqlServerApiKeyStoreMigrator`) | Add jitter to `SqlServerSecretsStoreMigrator`'s backoff in `~/Desktop/scadaproj/ZB.MOM.WW.Secrets` (mirror the Auth fix) and add a `Migrate_Concurrently_FromEightTasks_AllSucceed`-shaped live test to catch a regression. Lives entirely in scadaproj, not this repo. | Next time Secrets' SQL Server migrator is touched, or if a wider-than-2-way concurrent boot of a Secrets-backed cluster is ever planned. |
 | 110 | **Flow Debugger follow-ups: the *Vertical trace* list toggle (mockup Direction B) and console capture on `ScriptRun`** *(Low)*. v1 ships the Direction A swimlane only; the mockup's Direction B — the same steps as a vertical, filterable list with the lane as a column — was kept as an alternate for long flows and screen readers, and the detail panel's *Console* tab is absent because script `Console`/log output is not captured per run (`ScriptRun` rows carry parameters, return value, error and timing, not stdout). Both are additive: a list view over the existing `FlowGraph`, and an extra `Extra.console` field on the `ScriptRun` row's `ScriptTraceExtra` (payload cap applies). | Design `docs/plans/2026-09-05-flow-debugger-design.md` §11; plan `2026-09-05-flow-debugger.md` Task 23 | Neither was asked for by an operator; the swimlane + Timing/Writes tabs cover the acceptance flow (Delmia recipe download, rig step H), and console capture needs a per-run writer seam in `ScriptRuntimeContext` plus a redaction decision. | First operator request for a list view or for script log lines in the step detail. |
-| 111 | **Flow Debugger outbound nodes: no Retry/Discard on a parked node, and no `?correlationId=` deep link from the node to the Site Calls / Notification report pages** *(Low)*. v1.1 (plan `docs/plans/2026-09-06-flow-debugger-outbound-calls.md`) draws every `ExternalSystem.*` / `Database.*` / `Notify.Send` a traced run makes as one node on the External lane and folds the cached call's / notification's later lifecycle into it (a `Parked` pill + a Lifecycle tab), but the node itself is read-only: the hint says "Retry or discard from Site Calls / Notification report" as text, without a link, and there is no per-attempt request/response diff. Both actions already exist on those pages (central→site `RetryParkedOperation` / `DiscardParkedOperation` relay; Notification Outbox Retry/Discard) and the row's `CorrelationId` (`TrackedOperationId` / `NotificationId`) is on the folded step's lifecycle rows, so a deep link is additive — the pages just don't accept a `?correlationId=` query today. | Plan 2026-09-06 "Out of scope"; `FlowStepDetail.razor` parked hint | The Site Calls page owns the retry semantics and its audit rows; duplicating the action on the debugger node would need the same Deployer gate + confirm flow. | First operator who reaches a parked node from the debugger and asks for the button. |
+| 111 | ~~**Flow Debugger outbound nodes: no Retry/Discard on a parked node, and no `?correlationId=` deep link from the node to the Site Calls / Notification report pages** *(Low)*~~ **RESOLVED 2026-09-06 (plan `docs/plans/2026-09-06-flow-debugger-followups.md`).** `FlowStep` now carries the row's `CorrelationId`; the detail panel deep-links to `/site-calls/report?correlationId=` / `/notifications/report?correlationId=` (both pages accept it through additive per-id query filters — `SiteCallQueryRequest.TrackedOperationIdFilter`, `NotificationOutboxQueryRequest.NotificationIdFilter` — pre-filter to the row and auto-open its detail), and a `Parked` node offers Retry / Discard in place through `IFlowDebugService.RetryOutboundAsync` / `DiscardOutboundAsync`, which reuse the report pages' relay, site-scope re-check and confirm wording, after which the page re-polls Replay until the node leaves Parked. Per-attempt request/response diff is still not shown (the lifecycle rows carry the error summary only). Found on the way: the prediction circuit deadlock (`4769e192`). | Plan 2026-09-06 "Out of scope"; `FlowStepDetail.razor` parked hint | The Site Calls page owns the retry semantics and its audit rows; duplicating the action on the debugger node would need the same Deployer gate + confirm flow. | First operator who reaches a parked node from the debugger and asks for the button. |
 | 68 | ~~**`deploy.sh` run from a git worktree silently rehomes every node's bind-mount data dir**~~ **RESOLVED 2026-08-15 (guard added in the same close-out).** The compose files' bind mounts are relative (`./site-a-node-a/data`), so a deploy from a worktree checkout mounts the worktree's copies — the rig keeps running and looks healthy, but its SQLite stores split from the main checkout's and everything written there is orphaned by the next deploy from main. Bit the rows-46–53 close-out live: the seeding agent's `rig-probe-1` deploy persisted into worktree-homed dirs and "vanished" after the orchestrator's redeploy (no tombstone, no product bug — LWW/tombstone forensics ruled out deletion; the row sat in `.claude/worktrees/…/docker/site-a-node-a/data/site-localdb.db` the whole time). Both `docker/deploy.sh` and `docker-env2/deploy.sh` now refuse to run from a `.claude/worktrees/` path (override: `SCADABRIDGE_ALLOW_WORKTREE_DEPLOY=1`). | Found during the rows-46–53 close-out | Closed 2026-08-15. | — |
