Mahdi Bazrafshan d3f8a9a5e5 docs: add project documentation and task tracking
Why:
- Need to track domain model, ADRs, task progress, and feature planning

Changes:
- CONTEXT.md: domain model with ADRs 0001-0014
- docs/tasks.md: updated task list with Phase 6 (Dashboard)
- docs/cant-do-yet.md: backend-ready but no UI features
- docs/out-of-scope-v1.md: intentionally excluded features

Impact:
- Project documentation centralized for reference

What You Can't Do Yet (But Backend Is Ready)

Features where the backend API is implemented and tested, but the dashboard UI does not yet expose them.

1. Chunk Preview Panel (Admin Tab)

Backend: GET /admin/chunks/{doc_id}?strategy=... returns all chunks for a document and strategy — chunk text (truncated to 500 chars), chunk index, token count, character count, parent_id.

Missing UI: No panel in the Admin tab to select a document + strategy and visualize the actual chunk text blocks, their sizes, and hierarchy.

2. Questions Dataset Management (Admin Tab)

Backend:

  • GET /admin/questions — lists JSON files in files/ with question counts
  • POST /admin/questions/upload — uploads a new questions JSON file
  • GET /admin/questions/{file_id} — returns full question set
  • DELETE /admin/questions/{file_id} — deletes a question file

Missing UI: No section in the Admin tab to browse, upload, view, or delete question datasets. You can only use the default files/questions.json by typing its path in the Benchmarks tab.

3. Standalone Cost Estimator (Admin Tab)

Backend: POST /admin/cost-estimate accepts num_questions and num_strategies, returns full cost breakdown (embedding, queries, evaluation, token estimates, total USD).

Missing UI: No standalone cost estimation panel in the Admin tab. The Benchmarks tab has a "Cost Estimate" button, but it is tied to the benchmark form and requires a document selection.

4. Experiment Detail View (Benchmarks Tab)

Backend: GET /benchmarks/{experiment_id} returns full experiment data — per-question results, per-strategy scores, aggregate metrics, benchmark config.

Missing UI: Dashboard shows a list of experiments with a "Report" link that opens the raw HTML report in a new tab. No in-dashboard detail view with side-by-side strategy comparison tables, per-question drill-down, or visual charts.

5. Query History (Query Tab)

Backend: GET /queries/{query_id} retrieves any past query. All queries are stored in SQLite with full results (answer, retrieved chunks, latency, tokens).

Missing UI: No list of past queries. When you navigate away from the Query tab, the current result disappears from the screen. There is no history panel to browse, search, or re-view previous questions and answers.

6. Document Content Preview (Documents Tab)

Backend: GET /documents returns parsed_text_preview and document_tree fields in the detail response model (DocumentDetailResponse). SQLite stores the full parsed text and document tree.

Missing UI: You can upload and process documents, but you cannot preview the actual document text or the hierarchical document tree (sections, articles, paragraphs) inside the dashboard.

7. Real-Time Processing Status (Documents Tab)

Backend: The processing endpoint (POST /documents/{id}/process) returns per-strategy results — strategies_completed and strategies_failed with status, chunk counts, and error messages.

Missing UI: When you click "Process", the button shows a spinner. You don't see which strategies are running, which have completed, or which failed. If it fails partway through 5 strategies, you don't know which one broke without checking the server logs.

8. Global Error Handling and Retry

Missing: If the server returns an error (network down, Qdrant disconnected, OpenAI rate limit), you see a toast notification that disappears after 3 seconds. There is no retry button, no persistent error banner, and no automatic reconnection. A failed operation must be manually re-attempted by clicking the button again.
