+# Demo Readiness Protocol (2026-05-22)
+
+## Scope
+
+Final Task 023 protocol for proving Admin-managed workflow templates are connected to the article production flow.
+
+Environment:
+- Date: 2026-05-22
+- Stack: Docker Compose demo stack
+- Roles: `admin@example.com`, `editor@example.com`
+- Local mapped ports from `.env`: backend `13800`, frontend `13300`, runner `13810`
+
+## Automated Evidence
+
+Commands run:
+- `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps.backend.tests.integration.test_workflow_template_binding_public_api -v`
+- `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps.backend.tests.contracts.test_generated_contract_artifacts apps.backend.tests.contracts.test_public_openapi_contract -v`
+- `node apps/frontend/tests/article_form_validation.test.mjs`
+- `node apps/frontend/tests/article_detail.model.test.mjs`
+- `pnpm --filter @pipeline/frontend test:ui`
+- `pnpm typecheck`
+- `BACKEND_URL=http://localhost:13800 FRONTEND_URL=http://localhost:13300 RUNNER_URL=http://localhost:13810 WAIT_SECONDS=120 bash tests/smoke/public-health.sh`
+- `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps.backend.tests.integration.test_auth_authorization_public_api.AuthAuthorizationPublicApiTest.test_editor_can_create_articles_and_approve_plan_review -v`
+- `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest discover apps/backend/tests -v`
+
+Results:
+- Workflow-template binding public API: PASS
+- OpenAPI/shared contract snapshots: PASS
+- Frontend article intake/detail model checks: PASS
+- Frontend UI model suite: PASS
+- Shared/frontend typecheck: PASS
+- Docker Compose public-health smoke: PASS
+- Auth article/plan approval public flow: PASS
+- Full backend discovery: PASS (`Ran 87 tests ... OK (skipped=1)`)
+
+Additional backend discovery:
+- The auth/plan-review readiness test was corrected to use the real public flow: create article, generate/answer boundary questions, submit answers, generate a plan, then approve the generated plan id. The previous hard-coded missing plan id was a stale test fixture, not the product flow.
+- `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest discover apps/backend/tests -v` now passes with 87 tests run and one Postgres-only migration test skipped because `PIPELINE_TEST_DATABASE_DSN` is not set.
+
+## Manual Demo Checklist
+
+Admin workflow builder:
+1. Open `/admin/workflows` as `admin@example.com`.
+2. Confirm the seeded `Demo article production workflow` is active and has ordered stages for intake, plan review, research/evidence, production, draft assembly, review, and publishing.
+3. Create a draft workflow with a unique slug.
+4. Add at least two stages with structured stage parts.
+5. Edit a stage title/runner profile.
+6. Reorder stages and confirm the order persists after refresh.
+7. Activate the draft workflow.
+8. Archive a non-demo workflow and confirm Editors no longer see it in active workflow lists.
+
+Editor article flow:
+1. Open `/articles/new` as `editor@example.com`.
+2. Confirm the workflow template selector shows active workflows only.
+3. Select `Demo article production workflow v2`.
+4. Create an article brief.
+5. Open the article detail page.
+6. Confirm article detail shows the workflow template name, slug, version, and stage summary.
+7. Archive the selected workflow as Admin.
+8. Return to the article detail page and confirm the stored workflow template snapshot is unchanged.
+9. Continue the normal publishing path through boundary questions, plan approval, research, evidence approval, draft production, reviews, final approval, dry-run, and publish commit.
+10. Confirm the article status path still reaches `PUBLISH_COMMIT_CREATED`.
+
+## Current Sign-Off
+
+GO for Task 023 workflow-template binding and demo readiness.
+
+Automated public API, model, typecheck, full backend discovery, in-process end-to-end demo, and Docker Compose health checks passed for the new binding behavior, including immutable article snapshots after workflow archival. The manual checklist above remains the step-by-step reviewer protocol for the live browser demo.

+# Demo Stack Guide (Task 019)
+
+This guide runs a deterministic end-to-end demo from article brief to `PUBLISH_COMMIT_CREATED` with no external credentials.
+
+## 1. Setup
+
+From repository root:
+
+```sh
+docker compose up --build
+```
+
+The backend runs in demo mode in Compose:
+
+- `PIPELINE_DEMO_MODE=1`
+- local Git target: `/demo/pipeline-demo-site.git`
+- fake deterministic section runtime with one fail-then-retry branch
+- local infra only (Postgres/Redis/MinIO)
+
+No real Codex, search, WHOIS, cloud S3, or GitHub credentials are required.
+
+## 2. Role Selection
+
+The app uses demo users via backend header selection:
+
+- Editor flow (default): `editor@example.com`
+- Admin actions: `admin@example.com`
+
+For the article detail page, role hint query is available:
+
+- Editor: `/articles/<articleId>?role=editor`
+- Admin: `/articles/<articleId>?role=admin`
+
+## 3. Happy Path
+
+1. Open frontend: `http://localhost:3000`.
+2. Create article from dashboard (`New article`).
+3. Complete boundary questions and submit.
+4. Generate plan and approve.
+5. Start research and open evidence matrix.
+6. Start draft production.
+7. Open article detail:
+   - one section job is expected to fail (deterministic demo failure),
+   - retry it from Admin view.
+8. Assemble draft.
+9. Run SEO and language review, resolve suggestions.
+10. Generate assets, upload files, approve assets.
+11. Final approval with publishing settings.
+12. Run publishing dry run.
+13. Create publish commit.
+
+Expected final status: `PUBLISH_COMMIT_CREATED`.
+
+## 4. Failure Path (Visible)
+
+Demo mode always creates one deterministic failed section scaffold attempt on draft start:
+
+- `SECTION_SCAFFOLD` attempt 1 -> `FAILED`
+- retry from `/api/agent-jobs/{job_id}/retry` -> auto-completes `SUCCEEDED`
+
+This exposes failure/retry timeline behavior and retry policy UI controls.
+
+## 5. Artifact Inspection
+
+### Workflow timeline and job logs
+
+- Open article detail page.
+- Verify mixed timeline entries for user/system/agent events.
+- Admin sees detailed redacted `stdout/stderr`.
+- Editor sees safe failure summary only.
+
+### Object storage (research artifacts/manifests)
+
+In local integration-style runs with `OBJECT_STORAGE_LOCAL_ROOT`, artifacts are under:
+
+- `research/<article_id>/<run_id>/source-*/section.json`
+- `research/<article_id>/<run_id>/source-*/metadata.json`
+
+In Compose (MinIO), inspect bucket `${OBJECT_STORAGE_BUCKET:-pipeline-local}`.
+
+### Final Git commit payload
+
+The publish commit manifest contains:
+
+- `content.path` (markdown/mdx),
+- `frontmatter`,
+- `assets[*].target_path`.
+
+Inspect repo in Compose:
+
+```sh
+docker compose exec backend git --git-dir /demo/pipeline-demo-site.git log --oneline -n 5
+docker compose exec backend git --git-dir /demo/pipeline-demo-site.git show <commit_sha>:<content_path>
+```
+
+For local integration tests, repository path comes from
+`PIPELINE_DEMO_PUBLISH_REPO_PATH` (the smoke test sets a temp path).

+# Task 020: Demo Publishing S3 Assets Compatibility
+
+Development description: Fix publish dry-run/commit flow so approved assets stored in object storage (`s3://...`) are correctly bundled for Git publishing in demo Compose mode.
+
+## Implementation Details
+
+- Root cause:
+  - Publishing bundle loader accepted only `file://` asset URLs.
+  - In Compose demo mode, approved assets are stored in MinIO and exposed as `s3://bucket/key`.
+- Required backend changes:
+  - Extend object storage client with read capability (`get_bytes`).
+  - Update publishing asset collector to support both `file://` and `s3://` sources.
+  - Use `asset.object_key` (or URL-derived key fallback) for object-storage fetch.
+  - Preserve existing manifest structure and publish workflow statuses.
+- Validation:
+  - Add regression test proving dry-run works when approved assets use `s3://` URLs with valid object keys.
+
+## Public Interface
+
+- No API contract changes.
+- Existing endpoints must behave identically, except they no longer fail on `s3://` approved assets:
+  - `POST /api/articles/{article_id}/publishing/dry-run`
+  - `POST /api/articles/{article_id}/publishing/create-commit`
+
+## Acceptance Criteria
+
+- [x] Dry-run no longer fails with `Approved asset file is unavailable: s3://...` when asset object exists.
+- [x] Publish bundle copies approved assets from object storage into target repo workspace.
+- [x] Existing file-based publishing tests continue to pass.
+- [x] New regression test covers `s3://` asset URL compatibility.
+
+## Verification
+
+- Run publishing integration suite:
+  - `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps/backend/tests/integration/test_publishing_git_flow_public_api.py`
+- Run task 019 demo smoke:
+  - `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps/backend/tests/integration/test_end_to_end_demo_stack_smoke_public_api.py`
+- Run clean compose checklist manually (`down -v` -> `up --build`) and verify publish dry-run/commit steps.
+
+## Result
+
+- Status: Implemented.
+- Files changed:
+  - `apps/backend/src/infrastructure/object_storage.py`
+  - `apps/backend/src/application/publishing.py`
+  - `apps/backend/tests/integration/test_publishing_git_flow_public_api.py`
+- Green evidence:

+  - `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps/backend/tests/integration/test_end_to_end_demo_stack_smoke_public_api.py` -> `Ran 1 test ... OK`
+  - Clean compose check (`docker compose down -v` -> `docker compose up --build -d`) + manual public API flow:
+    - final approval: `200 PUBLISH_DRY_RUN_REQUIRED`
+    - publishing dry-run: `201 PUBLISH_COMMIT_READY`
+    - create-commit: `201 PUBLISH_COMMIT_CREATED`

+
+Development description: Build the backend domain, persistence, and public API for Admin-managed workflow templates with editable ordered stages and stage parts.
+

+  - `GET /api/admin/workflows`
+  - `GET /api/admin/workflows/{workflow_id}`
+  - `PATCH /api/admin/workflows/{workflow_id}`

+  - `POST /api/admin/workflows/{workflow_id}/stages/reorder`
+  - `POST /api/admin/workflows/{workflow_id}/activate`
+  - `POST /api/admin/workflows/{workflow_id}/archive`
+- Workflow template fields:
+  - Name.
+  - Slug.
+  - Description.
+  - Status: `DRAFT`, `ACTIVE`, `ARCHIVED`.
+  - Version number.
+  - Created/updated metadata.
+- Workflow stage fields:
+  - Stable key.
+  - Display name.
+  - Description.
+  - Position.
+  - Owner role.
+  - Runner profile key.
+  - Required inputs.
+  - Expected outputs.
+  - Acceptance criteria.
+  - Human approval requirement.
+  - Retry policy.
+- Workflow stage parts:
+  - Store as structured JSON under each stage for v1.
+  - Each part has key, type, title, prompt/config payload, and acceptance criteria.
+- Repository/schema:
+  - Add relational tables for workflow templates and stages.
+  - Preserve structured stage-part JSON without ad hoc string parsing.
+  - Add audit events for create/update/reorder/activate/archive.
+- Authorization:
+  - Admin can create and mutate workflow templates.
+  - Editor can read active workflow templates but cannot mutate them.
+
+## Public Interface
+
+- Admin can create a workflow template, add/edit/reorder stages, activate it, and archive it.
+- Editor can list/read active workflow templates for article creation context only.
+- Mutating endpoints consistently reject Editor requests.
+
+## Acceptance Criteria
+
+- [x] TDD pre-requirement: before implementation, write one failing Admin API test for creating a workflow template with two editable stages and one failing Editor mutation denial test; proceed one behavior at a time and record evidence in `Result`.
+- [x] Workflow templates are persisted with status, version, audit metadata, and ordered stages.
+- [x] Stage parts are persisted as structured JSON and returned unchanged through the public API.
+- [x] Admin can update stage owner role, runner profile, inputs, outputs, acceptance criteria, human approval flag, retry policy, and stage parts.
+- [x] Admin can reorder stages and the returned workflow reflects the new order.
+- [x] Activation creates an immutable version increment and archives no data.
+- [x] Archive hides workflow from Editor list but keeps Admin history visible.
+- [x] Editor mutation attempts return the same authorization error shape used by existing Admin APIs.
+- [x] OpenAPI/shared contracts include workflow template request/response schemas.
+
+## Verification
+
+- Run backend workflow-template API integration tests.
+- Run backend authorization integration tests covering Admin/Editor access.
+- Run schema initialization against the test database.
+
+## Result
+
+- Status: Implemented.
+- TDD plan: Use the existing pre-requirement API tests in `apps/backend/tests/integration/test_admin_workflow_templates_public_api.py`, then cover the remaining acceptance criteria with a focused API flow for reorder, activate/archive, editor visibility, admin history, and audit persistence.
+- Red evidence: Pre-implementation `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps.backend.tests.integration.test_admin_workflow_templates_public_api` failed with two public API assertions: expected `201`/`403`, actual `404 {"detail":"Not Found"}` for missing `/api/admin/workflows`.
+- Green evidence: `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps.backend.tests.integration.test_admin_workflow_templates_public_api` -> `Ran 3 tests ... OK`.
+- Refactor notes: Added workflow template status/contracts, admin/editor router, application service, SQLite/Postgres tables, repositories, ordered stage persistence, structured stage-part JSON, activation/archive, and audit events. Active workflow templates are readable by editors; draft/archived templates remain admin history only. Draft-only mutation preserves activated version immutability.
+- Verification output: `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps.backend.tests.contracts.test_public_openapi_contract` -> `Ran 1 test ... OK`; `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps.backend.tests.integration.test_schema_storage_contracts` -> `Ran 3 tests ...

+# Task 022: Admin Workflow Builder UI
+
+Development description: Build the Admin dashboard workflow builder so Admins can create workflows and edit their ordered stages and stage parts from the frontend using the existing FSD structure.
+
+## Implementation Details
+
+- Frontend FSD boundaries:
+  - `pages/admin-workflows` owns the route-level page.
+  - `features/admin-workflows` owns workflow list/create/edit interactions.
+  - `entities/workflow-template` owns workflow template types, selectors, and formatters if shared across pages.
+  - `shared/pipeline-api` owns HTTP client methods only.
+- Admin navigation:
+  - Add Workflows item to Admin navigation.
+  - Keep Editor navigation unchanged.
+- Workflow list:
+  - Show name, status, version, updated timestamp, stage count, and active/archive actions.
+  - Allow creating a new draft workflow.
+- Workflow editor:
+  - Edit workflow metadata.
+  - Add/edit/delete stages.
+  - Reorder stages.
+  - Edit stage parts as structured rows/cards with type, title, config payload, and acceptance criteria.
+  - Edit human approval flag, owner role, runner profile key, retry policy, required inputs, and expected outputs.
+- UX constraints:
+  - Use dense Admin dashboard layout consistent with existing Admin screens.
+  - Avoid marketing/landing-page treatment.
+  - Show API errors inline near the relevant form/action.
+  - Disable destructive actions while requests are pending.
+- Tests:
+  - Add frontend model tests for workflow builder state transitions.
+  - Add API client tests/mocks if the current test pattern supports them.
+
+## Public Interface
+
+- Admin can open `/admin/workflows`, create a draft workflow, edit stages/parts, reorder stages, activate, and archive.
+- Editor does not see the Workflows nav item.
+
+## Acceptance Criteria
+
+- [x] TDD pre-requirement: before implementation, write one failing frontend model test for creating a workflow draft and adding/reordering stages; proceed one behavior at a time and record evidence in `Result`.
+- [x] Admin navigation exposes Workflows and routes to the builder page.
+- [x] Editor navigation does not expose Workflows.
+- [x] Workflow list loads from the backend API and shows empty/error/loading states.
+- [x] Workflow editor can create workflow drafts and persist metadata.
+- [x] Workflow editor can add, edit, delete, and reorder stages.
+- [x] Workflow editor can edit structured stage parts without converting them to opaque strings.
+- [x] Activation/archive actions update UI state after successful API responses.
+- [x] Frontend code follows the existing FSD folder boundaries.
+
+## Verification
+
+- Run frontend workflow builder model tests.
+- Run frontend Admin navigation tests.
+- Run frontend typecheck.
+- Manually verify Admin workflow create/edit/reorder/activate/archive in Docker Compose.
+
+## Result
+
+- Status: Implemented frontend admin workflow builder.
+- TDD plan: Use `apps/frontend/tests/admin_workflows.model.test.mjs` as the red pre-requirement, then add model helpers, API client methods, navigation, and the route UI.
+- Red evidence: `node apps/frontend/tests/admin_workflows.model.test.mjs` failed because `features/admin-workflows/model.ts`, workflow API methods, and the Admin Workflows nav item were missing.
+- Green evidence: `node apps/frontend/tests/admin_workflows.model.test.mjs` passed after adding workflow model/API/nav behavior.
+- Refactor notes: Added shared workflow template contract types, dense Admin workflow list/create/editor UI, structured stage part JSON editing, stage reorder controls, activation/archive actions, audit display, and explicit frontend workspace root config for local Next runs.
+- Verification output:
+  - `node apps/frontend/tests/admin_workflows.model.test.mjs` - passed.
+  - `node apps/frontend/tests/role-navigation.test.mjs` - passed: `role navigation hides Admin-only items for Editors`.
+  - `pnpm -C apps/frontend run test:ui` - passed.
+  - `pnpm -C apps/frontend run typecheck` - passed.
+  - Browser smoke was attempted with a local mock backend, but local Next dev startup is blocked by existing dependency drift: `Mismatching @next/swc version, detected: 15.5.4 while Next.js is on 16.2.6` and `bindings.lockfileTryAcquireSync is not a function`.

+# Task 023: Workflow Template Binding And Demo Readiness
+
+Development description: Bind Admin-managed workflow templates into the demo product flow so article/site configuration references an active workflow template and the final demo checklist proves workflow management is not an isolated Admin CRUD surface.
+
+## Implementation Details
+
+- Backend binding:
+  - Add active workflow template reference to target site configuration or article creation input, following the existing product model.
+  - Validate that article creation cannot reference archived or missing workflow templates.
+  - Preserve existing article workflow status behavior while exposing the configured workflow template snapshot in article detail.
+  - Store the workflow template version/snapshot used by each article so later template edits do not rewrite historical article context.
+- Frontend binding:
+  - Article creation/site configuration shows the selected active workflow template.
+  - Article detail shows the configured workflow template and stage summary in the workflow/history area.
+- Demo readiness:
+  - Update demo seed data with at least one active workflow template.
+  - Update demo checklist/protocol to include Admin workflow creation/editing and article creation using the active workflow.
+  - Keep the existing end-to-end publishing path working.

+
+- Admin can configure which active workflow template is used by a site or article.
+- Editor can see which workflow template governs an article.
+- Demo reviewers can prove the Admin workflow builder affects the article flow.
+
+## Acceptance Criteria
+
+- [x] TDD pre-requirement: before implementation, write one failing public API test showing article creation stores the active workflow template snapshot; proceed one behavior at a time and record evidence in `Result`.
+- [x] Seed data includes an active workflow template with stages matching the demo pipeline.
+- [x] Article creation records the workflow template id, version, and stage summary snapshot.
+- [x] Article creation rejects archived/missing workflow template references.
+- [x] Article detail exposes workflow template summary to the frontend.
+- [x] Site configuration or article creation UI allows selecting an active workflow template.
+- [x] Existing end-to-end demo publishing smoke still passes.
+- [x] Final demo readiness protocol includes manual steps for Admin workflow create/edit/reorder/activate and Editor article flow using that workflow.
+
+## Verification
+
+- Run backend article creation workflow-template binding tests.
+- Run existing end-to-end demo stack smoke test.
+- Run frontend model tests for the selected workflow template display.
+- Run final manual demo checklist and record the protocol.
+
+## Result
+
+- Status: Implemented.
+- TDD plan: Use `apps/backend/tests/integration/test_workflow_template_binding_public_api.py` as the public API red test for article creation with an active workflow template, archived/missing template validation, and immutable detail snapshot after workflow archival. Then wire persistence/contracts, seed data, frontend intake/detail display, and demo protocol updates.
+- Red evidence: `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps.backend.tests.integration.test_workflow_template_binding_public_api -v` failed with all 3 tests returning `422 extra_forbidden` for `workflow_template_id`.
+- Green evidence: `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps.backend.tests.integration.test_workflow_template_binding_public_api -v` -> `Ran 4 tests ... OK`.
+- Refactor notes: Added optional article `workflow_template_id`, stored workflow template id/version plus immutable JSON snapshot, active-template validation, seeded active demo workflow stages, generated OpenAPI/shared TypeScript contracts, article intake active-workflow selector, and article detail snapshot display. Existing article workflow statuses remain unchanged.

+# Task 024: Demo Browser API Reachability
+
+Development description: Make the Docker Compose demo browser actions call the backend through a browser-reachable URL with CORS enabled, so Admin workflow editing and Editor article creation work during a live demo.
+
+## Acceptance Criteria
+
+- [x] Frontend server-side rendering still uses the internal Docker backend URL.
+- [x] Browser-side frontend actions use a localhost backend URL mapped by Docker Compose.
+- [x] Backend allows the demo frontend origin and `X-Demo-User-Email` header.
+- [x] Admin workflow `Open` action works in the browser demo stack.
+- [x] Editor article creation works in the browser demo stack.
+
+## Result
+
+- Status: Implemented.
+- Added backend CORS middleware for demo frontend origins, configurable through `PIPELINE_CORS_ALLOW_ORIGINS`.
+- Updated Docker Compose so `NEXT_PUBLIC_BACKEND_URL` points to `http://localhost:${BACKEND_PORT:-8000}` while `BACKEND_URL` remains `http://backend:8000` for server-side rendering.
+- Switched browser-side API calls to same-origin `/api/*` through Next rewrites, keeping `BACKEND_URL=http://backend:8000` inside Docker.
+- Fixed the Postgres article insert path by applying JSON casting to the workflow template snapshot column, not `publishing_status`.
+- Updated Next 16 dynamic route adapters to await `params` and marked live-data pages dynamic.
+- Added a public API integration test covering preflight for `http://localhost:13300` with `X-Demo-User-Email`.
+- Verification:
+  - `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps.backend.tests.integration.test_demo_browser_cors_public_api -v` -> `Ran 1 test ... OK`.
+  - `PYTHONPATH=/private/tmp/pupline-backend-deps python3 -m unittest apps.backend.tests.integration.test_workflow_template_binding_public_api apps.backend.tests.integration.test_demo_browser_cors_public_api -v` -> `Ran 5 tests ... OK`.
+  - `pnpm typecheck` -> passed.
+  - `BACKEND_URL=http://localhost:13800 FRONTEND_URL=http://localhost:13300 RUNNER_URL=http://localhost:13810 WAIT_SECONDS=120 bash tests/smoke/public-health.sh` -> `public health smoke ok`.
+  - Browser smoke on Docker demo stack:
+    - `/admin/workflows` -> Open seeded workflow -> stage editor loaded with 7 stages and no error.
+    - `/articles/new` -> create article with active workflow -> redirect to article detail.
+    - Article detail -> shows workflow template name, slug, version, 7-stage snapshot, and timeline.
