 - Aligned configuration with the deployed Canopy realm shape: allowed origins, internal metadata address, public/valid issuer, `canopy-web` client ID, server-only client secret placeholder, and disabled HTTPS metadata for the current HTTP Keycloak endpoint.
 - Added a server-side `.env` configuration loader so `Keycloak__ClientSecret` overrides the `appsettings.Development.json` placeholder at startup without exposing the secret to the React client.
 - Moved authorization-code and refresh-token exchange to backend endpoints so confidential-client authentication uses the server-side Keycloak client secret instead of failing in the browser callback.
+- Added `Logout` to `AuthenticationAuditEventType` and `RecordLogout(subject, succeeded, traceId)` to `IAuthenticationAuditStore` / `InMemoryAuthenticationAuditStore`.
+- Added `EndSessionAsync(idTokenHint)` to `IKeycloakTokenClient` / `KeycloakTokenClient` — POSTs to Keycloak `{authority}/protocol/openid-connect/logout` with `id_token_hint`, `client_id`, `client_secret`.
+- Added `id_token` to `KeycloakTokenResponse` and `IdToken?` to `AuthTokenSetResponse` so the id_token flows from Keycloak to the frontend.
+- Created `AuthLogoutController` at `POST /api/auth/logout` (AllowAnonymous): calls `EndSessionAsync`, records `SESSION_LOGOUT` audit event regardless of Keycloak availability, always returns 200 per AC #8.
+- Added `idToken?: string` to `AuthTokenSet` frontend type; updated `requestTokenSet` deserialization to include `idToken`.
+- Added `logout(idTokenHint, storage?)` to `authContracts.ts` — calls backend endpoint, clears token storage in `finally` so tokens are always cleared even when Keycloak is unreachable.

 ### Completion Notes List
 
 - Story context created and marked ready-for-dev.
+- Created `IAuditService` + `AuditEvent` general-purpose contract. `AuditEventType` constants centralise event names (SESSION_LOGIN, SESSION_LOGOUT, etc.). Interface is intentionally append-only: only `Record()` and `GetRecent()` — no delete or update methods (AC #4).
+- Created `AppendOnlyFileAuditService`: writes JSON Lines to daily-rotating `.jsonl` files in a configurable directory. Files are never deleted by the service (AC #2). `Record()` wraps IO failures in `AuditServiceUnavailableException` and propagates, blocking the caller (AC #5).
+- Updated `InMemoryAuthenticationAuditStore` to accept `IAuditService` via constructor injection. Each `Record*()` method enqueues to the in-memory queue (for fast test assertions) AND calls `IAuditService.Record()` for durable persistence. Exceptions from `IAuditService.Record()` propagate to the caller per AC #5.
+- Registered `IAuditService → AppendOnlyFileAuditService` in `Program.cs`. Log directory is configurable via `Audit:LogDirectory` configuration key (defaults to `<ContentRoot>/audit-logs`).
+- `InMemoryAuthenticationAuditStore` now uses constructor DI for `IAuditService` — satisfies AC #3 (calling features use shared contract, not own persistence).
+- Refactored `AuthEndpointTests` to use `AuthIntegrationTestFactory` (custom `WebApplicationFactory` subclass) that injects an in-memory `IAuditService` passthrough. This keeps integration tests file-system-independent while the real file service is validated by `AuditServiceTests`. AC #5 integration test confirms that a failing `IAuditService` blocks the authenticated session endpoint.
+- All 23 backend tests pass.
+- Applied review fixes: audit timestamps are normalized to UTC, audit required fields are validated before durable writes, `GetRecent` has bounded argument handling, token exchange/refresh paths write shared audit events, and authorization allowed/challenged/denied outcomes are centrally audited.
+- 2026-05-06: `dotnet test .\Campaign_Tracker.Server.Tests\Campaign_Tracker.Server.Tests.csproj /p:UseAppHost=false` passed (86 tests).

A reflection-based test (`ILegacyDataAccess_HasNoWriteMethods_AC2`) asserts no Insert/Update/Delete/Remove/Modify/Write/Save/Create/Upsert methods exist on the contract. `ReadOnlyCommandGuard.Validate(string sql)` provides a defense-in-depth runtime check for any future raw-ADO.NET implementation: rejects empty SQL, non-SELECT statements, and any SQL containing INSERT/UPDATE/DELETE/DROP/CREATE/ALTER/TRUNCATE/EXEC/EXECUTE/MERGE/REPLACE keywords (word-boundary match).
+- **AC #3** — All return types are sealed `record` types in `LegacyData/Models/`. Tests confirm strong typing of nullable fields, boolean bit columns, and `DateTime?` columns.
+- **AC #4** — Verified by static repo scan: no code outside `Campaign_Tracker.Server/LegacyData/` references `Jurisdiction`, `JurisCode`, `JCode`, `KitID`, or `KitId`. All consumers must obtain legacy data via `ILegacyDataAccess` from DI. Records are sealed and have no public mutable setters.
+- **DI** — `Program.cs` registers `ILegacyDataAccess → InMemoryLegacyDataAccess` as a singleton. Comment notes that a real Access-backed implementation can be swapped in via configuration when `LegacyDatabase:ConnectionString` is provided.
+- **Test Adjustment** — Updated `LegacyDomainModels_AreReadOnlySealedRecords_AC4` to recognize that C# positional records emit `init`-only setters via the `IsExternalInit` modifier; these are construction-only and do not violate AC #4. Plain public setters remain forbidden.
+- All 50 backend tests pass.
+- Applied review fixes: added `OleDbLegacyDataAccess`, register it when `LegacyDatabase:ConnectionString` is configured, prevent non-development fallback to seeded data, made join keys non-nullable in domain records, and hardened `ReadOnlyCommandGuard` for multi-statement/write-keyword edge cases while allowing literals/comments/bracketed identifiers.
+- 2026-05-06: `dotnet test .\Campaign_Tracker.Server.Tests\Campaign_Tracker.Server.Tests.csproj /p:UseAppHost=false` passed (86 tests).
+- 2026-05-06: `dotnet build .\campaign-tracker.sln /p:UseAppHost=false` passed with 0 warnings and 0 errors.

-GPT-5 Codex

 ### Debug Log References
 
 - Story generated from epic source and architecture/UX planning artifacts.
+- 2026-05-06: Implemented Story 1.7. Added `LegacyData/Schema/` module: `LegacyTableDefinition`/`LegacyColumnDefinition` records, `LegacySchemaBaseline` snapshot, `LegacySchemaBaselineParser` (parses the bundled Access dump), `ILegacySchemaInspector` + in-memory implementation, `LegacySchemaCompatibilityCheck`, `LegacySchemaCheckResult` with structured drift entries, `ILegacySchemaCheckHistory`, and `LegacySchemaReleaseGate` for CI integration. Wired DI in `Program.cs` and added a `--check-legacy-schema` CLI exit path before host run. Exposed admin-only API via `LegacySchemaController`.
+- 2026-05-06: Authored 16 backend tests (`LegacySchemaCompatibilityTests`) covering parser correctness, every drift category, pass-result fields, release-gate exit code, history ordering, and admin-endpoint integration (auth required, drift surfaced).
+- 2026-05-06: Added React `LegacySchemaCheckPanel` and `legacySchemaContracts` module with 5 new vitest specs (now part of 28 total client tests). Wired the panel into `WorkspaceShell` as the rendered view when an Admin selects the existing "Admin" menu item; non-admins continue to see the legacy operations table.
+- 2026-05-06: Verified end-to-end: `ASPNETCORE_ENVIRONMENT=Development dotnet run --check-legacy-schema` printed `[legacy-schema-check] PASS — 9 tables verified` and exited 0; `dotnet test` reported 86/86 green; `npx vitest run` 28/28 green; `tsc -b` and `eslint` clean; `vite build` succeeded.
 
 ### Completion Notes List
 
-- Story context created and marked ready-for-dev.
+- **AC #1** — Baseline captured at startup from `Initial Documents/Access_Schema.txt` (overridable via `LegacySchema:BaselineFile`). `LegacySchemaCompatibilityCheck` compares the baseline tables/columns against an `ILegacySchemaInspector`, keyed by name (case-insensitive). The default in-memory inspector mirrors the baseline so dev environments report no drift; production replaces this with an OleDb-backed reader.
+- **AC #2** — Failure result returns a structured `LegacySchemaDrift` per change. Every entry identifies the table, column (or `null` for table-level drift), and `ChangeType` enum value (`TableMissing`, `TableAdded`, `ColumnMissing`, `ColumnAdded`, `ColumnTypeChanged`, `ColumnSizeChanged`, `ColumnNullabilityChanged`). The `Detail` string includes baseline/live values for type and size deltas so the report is actionable without further code lookup.
+- **AC #3** — Pass result includes `Passed=true`, `TablesVerified` (count of baseline tables compared), `DriftCount=0`, and `CheckedAt` (a `DateTimeOffset` stamped via the injected `TimeProvider` so tests can pin time deterministically). The pass branch in `LegacySchemaReleaseGate.WriteReport` prints this in a single line for CI log capture.
+- **AC #4** — `LegacySchemaReleaseGate.ShouldRun(args)` recognises the `--check-legacy-schema` flag in `Program.cs`. When the flag is present, the host is built but the web pipeline is skipped: the check runs synchronously, the result is printed via `WriteReport`, the history singleton records the run, and the process returns `0` on pass / `1` on fail. CI/CD pipelines can wire this into a release step that blocks promotion on the non-zero exit code.
+- **AC #5** — `LegacySchemaController` is gated by the existing `ApplicationPolicy.AdminAccess` policy (Admin role or alias only). `POST /api/admin/legacy-schema/check` triggers a run and writes an audit event (`LEGACY_SCHEMA_CHECK_PASSED` / `LEGACY_SCHEMA_CHECK_FAILED`) through `IAuditService`. `GET /api/admin/legacy-schema/history` returns recent runs newest-first with their timestamps. The React `LegacySchemaCheckPanel` (rendered when an admin selects the existing "Admin" menu item) calls these endpoints, surfaces drift detail in an Ant Design `Table`, and renders an empty-state when no runs exist.
+- **History storage** — `InMemoryLegacySchemaCheckHistory` is a thread-safe queue capped at 200 entries; older runs are evicted oldest-first. `GetRecent` returns newest-first. The interface is registered via DI so a durable store can be swapped in later without controller or release-gate changes.
+- **Auditing** — Manual runs flow through the existing shared `IAuditService` from Story 1.5; no parallel audit pipeline was introduced.
+- **Tests** — 16 backend `xunit` tests cover parser format, full-file load, every drift category, pass-result invariants, release-gate exit codes (pass and fail), CLI flag detection, history ordering, controller authorization (Forbidden without Admin), happy-path admin flow, and a drift scenario where the inspector is replaced via DI to confirm the failure report flows to the API. 5 new client `vitest` specs cover summary formatting, POST/GET behavior, and error propagation. All 86 backend tests and 28 client tests pass.

+## Deferred from: fix-strictmode-oidc-callback-race (2026-05-06)

+- `pendingCallbackSequence` is not scoped to a specific callback invocation — if `useOidcSession` were ever mounted twice simultaneously, the second instance would skip CSRF validation and piggyback on the first's exchange. Pre-existing architectural assumption; low risk given single-mount usage, but worth an assertion if the hook gains wider use.

+# Sprint Change Proposal — Change 2: Logout Session Destruction
+
+**Date:** 2026-05-05 | **SM:** Bob | **Scope:** Minor
+
+## 1) Issue Summary
+
+- Trigger: Logout capability was omitted from the authentication stories (1.2 and 1.3), discovered during sprint review while stories are in `review` status.
+- Context: Without calling the Keycloak `end_session_endpoint`, the server-side session remains alive after client-side token removal — a security gap, not a cosmetic omission.
+- Evidence: OIDC RP-initiated logout requires an explicit end-session call; NFR7 requires auth events (including logout) to be logged within 5 seconds.
+
+## 2) Impact Analysis
+
+### Epic Impact
+
+- Epic 1 (`in-progress`): minor addition to two `review`-status stories. No timeline impact.
+
+### Story Impact
+
+| Story | Status | Change |
+|-------|--------|--------|
+| 1.3 — Keycloak OIDC Integration | `review` | Add ACs 6–8: end-session endpoint call, SESSION_LOGOUT audit event, graceful failure handling |
+| 1.2 — Workspace Shell & Ant Design Foundation | `review` | Add ACs 7–8: accessible logout control in shell header, Popconfirm guard |
+
+### Artifact Conflicts
+
+| Artifact | Change |
+|----------|--------|
+| PRD NFR7 | Clarified "authentication events" explicitly includes logout |
+| Architecture | Added OIDC Logout / End-Session section to 2026-05-05 addendum |
+| UX Design Spec | Added logout control placement spec to 2026-05-05 addendum |
+
+### Technical Impact
+
+- Backend: new `/api/auth/logout` endpoint calling Keycloak `end_session_endpoint` with `id_token_hint`; `SESSION_LOGOUT` audit event via shared audit service
+- Frontend: logout handler in workspace shell header (Ant Design Avatar/Dropdown user menu), Popconfirm guard, token storage clear, redirect to login
+- No database schema changes; no legacy table impact
+
+## 3) Recommended Approach
+
+**Option 1 — Direct Adjustment.** Both affected stories are in `review`, not `done`. Optimal correction window. Effort: Low. Risk: Low. Timeline impact: Zero.
+
+## 4) Detailed Change Proposals
+
+Applied directly to artifact files — see Change Proposals in the analysis above for before/after text.
+
+Files updated:
+- `_bmad-output/implementation-artifacts/1-3-keycloak-realm-configuration-oidc-integration.md` — ACs 6–8 added, task entries added, change log updated
+- `_bmad-output/implementation-artifacts/1-2-workspace-shell-ant-design-foundation.md` — ACs 7–8 added, task entries added, change log updated
+- `_bmad-output/planning-artifacts/prd.md` — NFR7 clarified
+- `_bmad-output/planning-artifacts/architecture.md` — OIDC end-session section added
+- `_bmad-output/planning-artifacts/ux-design-specification.md` — logout control placement spec added
+
+## 5) Implementation Handoff
+
+- Scope: **Minor** — development team handles directly
+- Handoff to: Dev team (Amelia — `bmad-agent-dev`) for Stories 1.2 and 1.3
+- Success criteria: Story 1.3 implements `end_session_endpoint` call + `SESSION_LOGOUT` audit event; Story 1.2 implements accessible logout control with Popconfirm; neither story marked `done` until logout ACs pass review
+
+## 6) Checklist Status
+
+- 1.1–1.3 Trigger & context: [x] Done
+- 2.1–2.5 Epic impact: [x] Done
+- 3.1–3.4 Artifact conflicts: [x] Done
+- 4.1–4.4 Path forward: [x] Done (Option 1 selected)
+- 5.1–5.5 Proposal components: [x] Done
+- 6.1 Checklist completeness: [x] Done
+- 6.2 Proposal accuracy: [x] Done
+- 6.3 User approval: [x] Done (approved by Daniel on 2026-05-05)
+- 6.4 sprint-status.yaml: [N/A] No status changes required — stories remain `review`
+- 6.5 Next steps: [x] Done — dev team resumes Stories 1.2 and 1.3 with new ACs

+- The "Log Out" action is keyboard-accessible and visible in all role workspaces (UX-DR10).
