# Audit Log ParentExecutionId — Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers-extended-cc:subagent-driven-development to execute this plan task-by-task (fresh implementer per task + spec review + code-quality review).

**Goal:** Add a `ParentExecutionId` column to the Audit Log so an execution spawned by another (first cut: an inbound API request that routes to a site script) records a pointer back to its spawner, making audit call chains traceable across the execution boundary.

**Architecture:** Additive nullable `ParentExecutionId` (`Guid`) on the audit row (Commons `AuditEvent`, central MS SQL `AuditLog`, site SQLite `auditlog.db`, gRPC `AuditEventDto`). The inbound API request's `ExecutionId` is minted once at the HTTP entry, threaded onto `RouteToCallRequest` → `ScriptCallRequest` → the routed script's `ScriptRuntimeContext` as a new `parentExecutionId`; the routed script still mints its own fresh `ExecutionId`. Every emitter stamps `ParentExecutionId` as a sibling to `ExecutionId` — through the S&F buffer for retry-loop cached rows and through `NotificationSubmit` → `Notifications.OriginParentExecutionId` for central `NotifyDeliver` rows. A recursive repository query plus a Central UI tree view reconstruct the chain. Validated design: `docs/plans/2026-05-21-audit-parent-executionid-design.md`.

**Tech Stack:** .NET 10, EF Core 10 (MS SQL + SQLite), Akka.NET, gRPC, Blazor Server + Bootstrap, System.CommandLine, xUnit + Akka.TestKit.Xunit2 + bUnit + NSubstitute/Moq, Playwright.

**Ground rules (every task):** branch is `feature/audit-parent-executionid` (already created) — never commit to `main`. TDD — write the failing test first, then the minimal implementation. Edit in place; never touch `infra/*` or `alog.md`; `docker/*` only if a task says so (none do). Stage with explicit `git add <path>` — never `git add .` / `commit -am`. Full solution stays green (`dotnet build ZB.MOM.WW.ScadaBridge.slnx` 0 warnings — `TreatWarningsAsErrors` is on; `dotnet test ZB.MOM.WW.ScadaBridge.slnx` for touched suites). Additive contract evolution only. Do not push.

---

## Task 0: Prep — verify branch + baseline

**Files:** none.

**Steps:** confirm `git branch --show-current` is `feature/audit-parent-executionid`; run `dotnet build ZB.MOM.WW.ScadaBridge.slnx` and confirm it succeeds with 0 warnings.

**Acceptance:** on the branch, solution builds clean.

---

## Task 1: Foundation — `AuditEvent.ParentExecutionId`, central `AuditLog` column, repository query

**Files:**
- Modify: `src/ZB.MOM.WW.ScadaBridge.Commons/Entities/Audit/AuditEvent.cs` — add `Guid? ParentExecutionId` (sibling to `ExecutionId`, same XML-doc style).
- Modify: `src/ZB.MOM.WW.ScadaBridge.Commons/Types/Audit/AuditLogQueryFilter.cs` — add `Guid? ParentExecutionId` single-value filter dimension (mirror `ExecutionId`).
- Modify: `src/ZB.MOM.WW.ScadaBridge.ConfigurationDatabase/Configurations/AuditLogEntityTypeConfiguration.cs` — map the column; add index `IX_AuditLog_ParentExecution (ParentExecutionId)`.
- Create: EF migration under `src/ZB.MOM.WW.ScadaBridge.ConfigurationDatabase/Migrations/` — `AddAuditLogParentExecutionId` — `ParentExecutionId uniqueidentifier NULL` + the index. Mirror `20260521184044_AddAuditLogExecutionId` exactly (partition-aligned index, metadata-only `ALTER`).
- Modify: `src/ZB.MOM.WW.ScadaBridge.ConfigurationDatabase/Repositories/AuditLogRepository.cs` — `QueryAsync` translates `filter.ParentExecutionId` to `e.ParentExecutionId == value` (mirror the `ExecutionId` clause). Keyset paging untouched.
- Test: `tests/ZB.MOM.WW.ScadaBridge.ConfigurationDatabase.Tests/Repositories/AuditLogRepositoryTests.cs` — `QueryAsync_FilterByParentExecutionId`; migration smoke if the suite has that pattern.

**Approach:** purely additive; `ParentExecutionId` is `Guid?` everywhere. Generate the migration the same way `AddAuditLogExecutionId` was produced (match the repo's migration workflow).

**Commit:** `feat(auditlog): ParentExecutionId column on AuditEvent + central AuditLog`

---

## Task 2: Foundation — site SQLite + gRPC DTO

**Files:**
- Modify: `src/ZB.MOM.WW.ScadaBridge.AuditLog/Site/SqliteAuditWriter.cs` — add `ParentExecutionId TEXT NULL` to the `auditlog.db` `AuditLog` table; the insert command binds it; `MapRow` reads it back. **Add the column via the idempotent `ALTER TABLE ... ADD COLUMN`-if-missing upgrade path** (the same path commit `5198b11` introduced for `ExecutionId` — locate it and extend it; do NOT rely on `CREATE TABLE IF NOT EXISTS` for the new column on an existing site DB).
- Modify: `src/ZB.MOM.WW.ScadaBridge.Communication/Protos/sitestream.proto` — add `string parent_execution_id` to `AuditEventDto` (next free field number; additive). Rebuild regenerates the C# stubs.
- Modify: `src/ZB.MOM.WW.ScadaBridge.Communication/Grpc/AuditEventDtoMapper.cs` — `ToDto`/`FromDto` map `ParentExecutionId` ↔ `parent_execution_id` (Guid ↔ string; empty string ↔ null, mirroring the existing `ExecutionId` handling).
- Test: `tests/ZB.MOM.WW.ScadaBridge.AuditLog.Tests/Site/SqliteAuditWriterSchemaTests.cs` — column present, round-trips, and the `ALTER`-if-missing path adds it to a pre-existing DB lacking the column; `tests/ZB.MOM.WW.ScadaBridge.Communication.Tests/AuditEventDtoMapperTests.cs` — `ParentExecutionId` round-trip incl. null.

**Commit:** `feat(auditlog): ParentExecutionId on site SQLite schema + gRPC AuditEventDto`

---

## Task 3: Inbound request id minting + `RouteToCallRequest.ParentExecutionId`

**What:** The id propagated as `ParentExecutionId` is the inbound API request's `ExecutionId`. Today `AuditWriteMiddleware` mints it late, only for the inbound audit row. Mint it once early and stash it so `InboundScriptExecutor` can carry it onto the routing RPC.

**Files:**
- Modify: `src/ZB.MOM.WW.ScadaBridge.Commons/Messages/InboundApi/RouteToInstanceRequest.cs` — add `Guid? ParentExecutionId` to the `RouteToCallRequest` record (additive — append as the last positional param with a default, or make it a settable init property; match how the codebase evolves records).
- Modify: `src/ZB.MOM.WW.ScadaBridge.InboundAPI/Middleware/AuditWriteMiddleware.cs` (+ `AuditWriteMiddlewareExtensions.cs` if the pipeline order needs it) — mint the request `ExecutionId` (`Guid.NewGuid()`) at the start of the request, stash it on `HttpContext.Items` under a well-known key (add a small constant, e.g. `InboundExecutionContext.HttpItemKey`); `EmitInboundAudit` reads that same id for the inbound row's `ExecutionId` instead of minting its own.
- Modify: `src/ZB.MOM.WW.ScadaBridge.InboundAPI/InboundScriptExecutor.cs` — read the stashed inbound `ExecutionId` from `HttpContext.Items` (or accept it as a parameter from the endpoint that has the `HttpContext`).
- Modify: `src/ZB.MOM.WW.ScadaBridge.InboundAPI/RouteHelper.cs` (~line where `RouteToCallRequest` is built) — set `ParentExecutionId` on the `RouteToCallRequest` from the inbound `ExecutionId`. Leave `RouteHelper`'s own per-op `CorrelationId` GUID alone — separate concern.
- Modify: `src/ZB.MOM.WW.ScadaBridge.InboundAPI/EndpointExtensions.cs` if the inbound `ExecutionId` must be plumbed from the endpoint into `InboundScriptExecutor`.
- Test: `tests/ZB.MOM.WW.ScadaBridge.InboundAPI.Tests/` — `AuditWriteMiddlewareTests` (inbound row uses the early-minted id; distinct per request); a `RouteHelper`/`InboundScriptExecutor` test that a routed `RouteToCallRequest` carries `ParentExecutionId` = the inbound request's `ExecutionId`.

**Approach:** the inbound request's own audit row stays top-level — `ParentExecutionId` is NOT set on it (it remains `NULL`). Only the spawn id flows outward on `RouteToCallRequest`. If the early mint cannot cleanly be shared between middleware and executor, STOP and report before guessing the pipeline shape.

**Commit:** `feat(inboundapi): mint inbound ExecutionId early, carry it as RouteToCallRequest.ParentExecutionId`

---

## Task 4: Thread `ParentExecutionId` into the routed script's `ScriptRuntimeContext`

**What:** Carry the `RouteToCallRequest.ParentExecutionId` site-side down to the routed script's `ScriptRuntimeContext`. The routed script still generates its own fresh `ExecutionId`.

**Files:**
- Modify: `src/ZB.MOM.WW.ScadaBridge.Commons/Messages/ScriptExecution/ScriptCallRequest.cs` — add `Guid? ParentExecutionId` (additive). This is the message `RouteInboundApiCall` builds.
- Modify: `src/ZB.MOM.WW.ScadaBridge.SiteRuntime/Actors/DeploymentManagerActor.cs` `RouteInboundApiCall` (~line 734) — set `ParentExecutionId = request.ParentExecutionId` on the `ScriptCallRequest` it builds from the `RouteToCallRequest`.
- Modify: `src/ZB.MOM.WW.ScadaBridge.SiteRuntime/Actors/InstanceActor.cs` `HandleScriptCallRequest` (~line 319) — forward `request.ParentExecutionId` onward.
- Modify: `src/ZB.MOM.WW.ScadaBridge.SiteRuntime/Actors/ScriptActor.cs` `HandleScriptCallRequest` (~line 175) — pass `ParentExecutionId` into the `ScriptExecutionActor` it spawns.
- Modify: `src/ZB.MOM.WW.ScadaBridge.SiteRuntime/Actors/ScriptExecutionActor.cs` — add an optional `Guid? parentExecutionId = null` ctor param; thread it through `ExecuteScript` into `new ScriptRuntimeContext(...)`.
- Modify: `src/ZB.MOM.WW.ScadaBridge.SiteRuntime/Scripts/ScriptRuntimeContext.cs` — add an optional `Guid? parentExecutionId = null` ctor param (sibling to the existing `executionId` param ~line 144); store `_parentExecutionId`; XML-doc it. Thread it to the helper sub-context types alongside `_executionId` (the inner `ExternalSystem`/`Database`/`Notify` helper structs at ~lines 386, 406, 1003 carry `_executionId` — give them `_parentExecutionId` too).
- Test: `tests/ZB.MOM.WW.ScadaBridge.SiteRuntime.Tests/` — a test that a `ScriptCallRequest` carrying `ParentExecutionId` produces a `ScriptRuntimeContext` whose `_parentExecutionId` is that value AND whose `ExecutionId` is freshly generated (distinct); a `RouteToCallRequest` → `ScriptCallRequest` mapping test on `DeploymentManagerActor`.

**Note for implementer:** this task only threads the value — no emitter stamps it yet (Task 5). A normal (tag/timer) script run passes no `ParentExecutionId`, so `_parentExecutionId` stays `null`. Verify the helper sub-context plumbing matches exactly how `_executionId` is already threaded; if the ctor param ordering is awkward, mirror the `executionId` decision documented at `ScriptRuntimeContext.cs:396`.

**Commit:** `feat(siteruntime): thread ParentExecutionId into the routed script's ScriptRuntimeContext`

---

## Task 5: Site script-side emitters stamp `ParentExecutionId`

**What:** Every audit row a `ScriptRuntimeContext` emits gets `ParentExecutionId = _parentExecutionId` alongside `ExecutionId = _executionId`.

**Files:**
- Modify: `src/ZB.MOM.WW.ScadaBridge.SiteRuntime/Scripts/ScriptRuntimeContext.cs`:
  - Sync `ApiCall` (`BuildCallAuditEvent` / the sync emission ~line 932): set `ParentExecutionId = _parentExecutionId`.
  - Cached script-side rows (`CachedSubmit`, immediate `ApiCallCached`/`CachedResolve` ~lines 582, 693, 759): set `ParentExecutionId = _parentExecutionId`.
  - `NotifySend` emission: set `ParentExecutionId = _parentExecutionId`.
- Modify: `src/ZB.MOM.WW.ScadaBridge.SiteRuntime/Scripts/AuditingDbConnection.cs` + `AuditingDbCommand.cs` — thread `_parentExecutionId` (sibling to the audit `_executionId` already threaded); sync `DbWrite` and cached DB-write rows set `ParentExecutionId = _parentExecutionId`.
- Test: extend `tests/ZB.MOM.WW.ScadaBridge.SiteRuntime.Tests/Scripts/ExternalSystemCallAuditEmissionTests.cs`, `DatabaseSyncEmissionTests.cs`, `ExternalSystemCachedCallEmissionTests.cs`, `DatabaseCachedWriteEmissionTests.cs`, `NotifySendAuditEmissionTests.cs`, `ExecutionCorrelationContextTests.cs` — assert `ParentExecutionId` is the context's `_parentExecutionId` on every emitted row; assert it is `null` when the context was constructed without one.

**Commit:** `feat(auditlog): site script-side emitters stamp ParentExecutionId`

---

## Task 6: Cached S&F retry-loop rows carry `ParentExecutionId`

**What:** Thread `ParentExecutionId` through the store-and-forward buffer so the retry-loop cached audit rows (`CachedCallLifecycleBridge`) carry it — a sibling to the `ExecutionId` the `ExecutionId` rollout already threaded through this exact path.

**Files:**
- Modify: the S&F buffered cached-call message / payload in `src/ZB.MOM.WW.ScadaBridge.StoreAndForward/` (`StoreAndForwardService.cs` and the buffered message type — find where `ExecutionId` was added in the `ExecutionId` rollout's Task 4) — carry `ParentExecutionId` alongside.
- Modify: `CachedCallAttemptContext` (in `src/ZB.MOM.WW.ScadaBridge.StoreAndForward/` / referenced by `src/ZB.MOM.WW.ScadaBridge.Commons/Interfaces/Services/ICachedCallLifecycleObserver.cs`) — add a `ParentExecutionId` field beside `ExecutionId`.
- Modify: `src/ZB.MOM.WW.ScadaBridge.AuditLog/Site/Telemetry/CachedCallLifecycleBridge.cs` `BuildPacket` — set `ParentExecutionId` from the context, beside the existing `ExecutionId`.
- Modify: the enqueue path (`ExternalSystem.CachedCall` / `Database.CachedWrite` in `ScriptRuntimeContext.cs` ~line 520, where `executionId: _executionId` is already passed into the buffered message) — also write `_parentExecutionId` into the buffered message.
- Test: `tests/ZB.MOM.WW.ScadaBridge.AuditLog.Tests/` cached-telemetry tests + `tests/ZB.MOM.WW.ScadaBridge.StoreAndForward.Tests/` — retry-loop rows carry the originating `ParentExecutionId` (incl. `null` for a non-routed run).

**Note for implementer:** the threading boundary is already open from the `ExecutionId` rollout — this is one more field at each existing carry point, not a new boundary. If the buffered message cannot cleanly carry it, STOP and report.

**Commit:** `feat(auditlog): thread ParentExecutionId through S&F for retry-loop cached rows`

---

## Task 7: Central `NotifyDeliver` rows carry `ParentExecutionId`

**Files:**
- Modify: `src/ZB.MOM.WW.ScadaBridge.Commons/Entities/Notifications/Notification.cs` — add `Guid? OriginParentExecutionId` (sibling to `OriginExecutionId`).
- Modify: `src/ZB.MOM.WW.ScadaBridge.Commons/Messages/Notification/NotificationMessages.cs` — `NotificationSubmit` carries `Guid? OriginParentExecutionId` (additive).
- Modify: `src/ZB.MOM.WW.ScadaBridge.ConfigurationDatabase/` — EF config for `Notifications` + a new migration `AddNotificationOriginParentExecutionId` (`Notifications.OriginParentExecutionId uniqueidentifier NULL`). Mirror `20260521193048_AddNotificationOriginExecutionId`.
- Modify: the site `NotifySend` forward path — the routed run's `_parentExecutionId` (on the `NotifySend` audit row from Task 5) also rides on the `NotificationSubmit` (set it where the submit is built — `ScriptRuntimeContext` `Notify.Send` / the S&F notification forwarder, beside `OriginExecutionId`).
- Modify: `src/ZB.MOM.WW.ScadaBridge.NotificationOutbox/NotificationOutboxActor.cs` — persist `OriginParentExecutionId` on insert; `BuildNotifyDeliverEvent` sets `ParentExecutionId = notification.OriginParentExecutionId`.
- Test: `tests/ZB.MOM.WW.ScadaBridge.NotificationOutbox.Tests/` — `NotifyDeliver` rows echo `OriginParentExecutionId`; `tests/ZB.MOM.WW.ScadaBridge.Commons.Tests/` contract shape.

**Commit:** `feat(auditlog): NotifyDeliver rows carry the originating ParentExecutionId`

---

## Task 8: Repository — `GetExecutionTreeAsync`

**What:** A repository method that, given any `ExecutionId`, returns the whole execution chain rooted at the topmost ancestor — for the Central UI tree view.

**Files:**
- Create: `src/ZB.MOM.WW.ScadaBridge.Commons/Types/Audit/ExecutionTreeNode.cs` — a record: `ExecutionId`, `ParentExecutionId`, `RowCount`, channels present, statuses present, `SourceSiteId`, `SourceInstanceId`, `FirstOccurredAtUtc`, `LastOccurredAtUtc`.
- Modify: `src/ZB.MOM.WW.ScadaBridge.Commons/Interfaces/` — the Audit Log repository interface gains `Task<IReadOnlyList<ExecutionTreeNode>> GetExecutionTreeAsync(Guid executionId, CancellationToken ct)`.
- Modify: `src/ZB.MOM.WW.ScadaBridge.ConfigurationDatabase/Repositories/AuditLogRepository.cs` — implement it:
  1. **Walk up** to the root — iterative `SELECT TOP 1 ParentExecutionId FROM AuditLog WHERE ExecutionId = @cur AND ParentExecutionId IS NOT NULL` until none; the last `ExecutionId` with no parent is the root. Cap the loop (e.g. 32) against corrupt data.
  2. **Walk down** — a recursive CTE seeded at the root, joining `child.ParentExecutionId = parent.ExecutionId`; `OPTION (MAXRECURSION 32)`. Project each distinct `ExecutionId` with the summary aggregates (`GROUP BY`).
  Use `FromSqlInterpolated`/raw SQL for the recursive CTE (EF Core cannot express it in LINQ); keep the SQL append-only-safe (SELECT only).
- Test: `tests/ZB.MOM.WW.ScadaBridge.ConfigurationDatabase.Tests/Repositories/AuditLogRepositoryTests.cs` — `GetExecutionTree_MultiLevelChain` (3-level chain returns all nodes rooted at the ancestor regardless of the entry node); `GetExecutionTree_StubParentNode` (a `ParentExecutionId` referencing an execution with no rows of its own yields a node with `RowCount = 0` / is surfaced as referenced); `GetExecutionTree_RespectsMaxRecursion`.

**Note for implementer:** chains are shallow (1–2 levels typical). The `ParentExecutionId` graph is acyclic by construction; `MAXRECURSION` is a guard, not a routine limit. A purged parent simply ends the upward walk.

**Commit:** `feat(auditlog): GetExecutionTreeAsync recursive execution-chain query`

---

## Task 9: Central UI — `ParentExecutionId` column, filter, parent drill-in

**Files:**
- Modify: `src/ZB.MOM.WW.ScadaBridge.CentralUI/Components/Audit/AuditResultsGrid.razor` (+ `.razor.cs`) — add `ParentExecutionId` to the column set (short form / monospace, like `ExecutionId`); it participates in the existing resize/reorder + `ColumnOrder`.
- Modify: `src/ZB.MOM.WW.ScadaBridge.CentralUI/Components/Audit/AuditFilterBar.razor` (+ `.razor.cs`) + `AuditQueryModel.cs` — a `ParentExecutionId` paste text-filter; `ToFilter` maps it to `AuditLogQueryFilter.ParentExecutionId`.
- Modify: `src/ZB.MOM.WW.ScadaBridge.CentralUI/Components/Pages/Audit/AuditLogPage.razor.cs` — `ApplyQueryStringFilters` accepts `?parentExecutionId=<guid>`; `BuildExportUrl` emits it.
- Add a "View parent execution" row/drilldown action (in `AuditDrilldownDrawer` and/or a grid row action) linking `/audit/log?executionId=<ParentExecutionId>`, shown only when the row has a non-null `ParentExecutionId`. Mirror the existing `?executionId=` drill-in.
- Test: `tests/ZB.MOM.WW.ScadaBridge.CentralUI.Tests/` bUnit (column renders, filter maps, query-param parsed, drill-in hidden when `ParentExecutionId` null); `tests/ZB.MOM.WW.ScadaBridge.CentralUI.PlaywrightTests/Audit/` (parent drill-in filters the grid).

Use the `frontend-design` skill for the column/filter/drill-in styling. Custom Blazor + Bootstrap only — no component frameworks.

**Commit:** `feat(centralui): ParentExecutionId column, filter and parent drill-in on the Audit Log page`

---

## Task 10: Central UI — execution-chain tree view

**What:** A page that renders the full execution chain (rooted at the topmost ancestor) as an expandable tree, reached via a "View execution chain" drill-in.

**Files:**
- Create: `src/ZB.MOM.WW.ScadaBridge.CentralUI/Components/Pages/Audit/ExecutionTreePage.razor` (+ `.razor.cs`) — route `/audit/execution-tree`, accepts `?executionId=<guid>`; calls `GetExecutionTreeAsync` via the same data path the Audit Log page uses for its grid (mirror that — repository service in-process, or a ManagementService endpoint if the grid goes through one; if the latter, add the endpoint in Task 11).
- Create: `src/ZB.MOM.WW.ScadaBridge.CentralUI/Components/Audit/ExecutionTree.razor` (+ `.razor.cs` + `.razor.css`) — a custom recursive Blazor tree component: assembles the tree from the flat `ExecutionTreeNode` list, renders expandable nodes each showing the execution summary (id short form, row count, channels/statuses, site/instance, time span); a node referenced as a parent but with `RowCount = 0` renders as a stub ("execution with no audited actions"); clicking a node navigates to `/audit/log?executionId=<node>`.
- Modify: `src/ZB.MOM.WW.ScadaBridge.CentralUI/Components/Audit/AuditDrilldownDrawer.razor` (+ `.razor.cs`) and/or `AuditResultsGrid` — add a "View execution chain" action linking `/audit/execution-tree?executionId=<ExecutionId of the row>`.
- Modify: the Central UI `Audit` nav group if the page should be linkable (decide — it is primarily a drill-in target; a nav entry is optional).
- Test: `tests/ZB.MOM.WW.ScadaBridge.CentralUI.Tests/` bUnit (tree assembled correctly from a flat list incl. multi-level + stub node; node click navigates); `tests/ZB.MOM.WW.ScadaBridge.CentralUI.PlaywrightTests/Audit/` (drill-in → tree renders → node click filters the Audit Log grid).

Use the `frontend-design` skill for the tree component. Clean, corporate, internal-use aesthetic; custom component, no frameworks.

**Commit:** `feat(centralui): execution-chain tree view on the Audit Log page`

---

## Task 11: CLI + ManagementService — `ParentExecutionId` filter

**Files:**
- Modify: `src/ZB.MOM.WW.ScadaBridge.CLI/Commands/AuditCommands.cs` + `AuditQueryHelpers.cs` — `audit query --parent-execution-id <guid>`; `AuditQueryArgs` + `BuildQueryString` emit `parentExecutionId`.
- Modify: `src/ZB.MOM.WW.ScadaBridge.ManagementService/AuditEndpoints.cs` `ParseFilter` — parse `parentExecutionId` query param into `AuditLogQueryFilter.ParentExecutionId` (lax-parse — unparseable dropped).
- Modify: `src/ZB.MOM.WW.ScadaBridge.CentralUI/Audit/AuditExportEndpoints.cs` `ParseFilter` — same.
- If Task 10's tree page goes through ManagementService rather than the repository in-process: add `GET /api/audit/execution-tree?executionId=<guid>` to `AuditEndpoints.cs` returning the `ExecutionTreeNode` list. Otherwise skip this bullet. No CLI `audit tree` command in the first cut.
- Test: `tests/ZB.MOM.WW.ScadaBridge.CLI.Tests/`, `tests/ZB.MOM.WW.ScadaBridge.ManagementService.Tests/AuditEndpointsTests.cs`.

**Commit:** `feat(audit): ParentExecutionId filter in the CLI and ManagementService`

---

## Task 12: End-to-end integration test + docs

**Files:**
- Create: `tests/ZB.MOM.WW.ScadaBridge.IntegrationTests/AuditLog/ParentExecutionIdCorrelationTests.cs` — boot a site+central pair; issue an inbound API request whose method script calls `Route.Call` into a site instance; the routed site script does a sync `ExternalSystem.Call`, a cached call, and a `Notify.Send`. Assert: every audit row the routed run produced (site + central, sync + cached lifecycle + `NotifySend`/`NotifyDeliver`) carries `ParentExecutionId` = the inbound request's `ExecutionId`; each routed-run row has its own distinct `ExecutionId`; the inbound `InboundRequest` row has `ParentExecutionId = NULL`. Assert `GetExecutionTreeAsync` returns both executions in one chain.
- Modify: `docs/requirements/Component-AuditLog.md` — add `ParentExecutionId` to the `AuditLog` schema table and the index list (`IX_AuditLog_ParentExecution`); extend the `ExecutionId vs CorrelationId` section with a paragraph on `ParentExecutionId` (cross-execution correlation; inbound→routed bridge; immediate-spawner tree; tag cascade deferred). (Do NOT modify `alog.md`.)
- Modify: `CLAUDE.md` — under the Centralized Audit Log decisions, one line noting `ParentExecutionId` as the cross-execution spawn pointer (inbound→routed-site-script bridge; tag cascade deferred).
- Modify: component #23 summary in `CLAUDE.md`'s Current Component List if it enumerates correlation columns (keep it in sync).

**Commit:** `test(auditlog): end-to-end ParentExecutionId correlation + docs`

---
