+# 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_publishing_git_flow_public_api.py` -> `Ran 7 tests ... OK`
+  - `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`
+- Refactor notes:
+  - Added storage read path to reuse existing object storage abstractions instead of introducing publish-specific S3 calls.
