+# Phase 9 Context: Material and Asset Workspace
+
+**Status:** Ready for execution
+**Started:** 2026-04-26
+
+## Goal
+
+Expose material ingestion, ontology inspection, and teaching asset prompt
+candidate generation in the web app.
+
+## Requirements
+
+- WEB-05: Operator can ingest source material from the web app.
+- WEB-06: Operator can inspect ontology candidate concepts, edges, and gaps.
+- WEB-07: Operator can generate and inspect teaching asset prompt candidates.
+- WEB-08: Web UI includes loading, empty, and error states for the MVP flows.
+
+## UX Direction
+
+Keep content operations as a secondary workspace below the diagnostic answer
+surface. The operator flow should show provenance and candidate status without
+turning the page into an admin dashboard.
+
+## Out of Scope
+
+- Full ontology editor.
+- Human review promotion controls.
+- Actual image generation.

+# Phase 9 Plan: Material and Asset Workspace
+
+**Status:** Ready for execution
+**Phase Goal:** Let operators use ontology and teaching asset prompt workflows
+from the web app.
+
+## Tasks
+
+### 1. Add material ingestion UI
+
+- Add title/source/body fields.
+- Call material ingestion API.
+- Show loading and error states.
+
+### 2. Add ontology inspection UI
+
+- Render concept, edge, and gap counts.
+- Show candidate concept labels and review states.
+- Populate asset concept selector.
+
+### 3. Add teaching asset prompt UI
+
+- Generate prompt candidate for selected concept and asset type.
+- Show prompt text, model key, review state, and verification guard.
+
+### 4. Verify
+
+- Update tests for content-operation frontend wiring.
+- Run Go tests, OpenSpec validation, line-count check, and smoke.
+
+## Out of Scope
+
+- Real image generation.
+- Ontology graph editor.

+# Phase 9 Research: Material and Asset Workspace
+
+## Findings
+
+The existing APIs are sufficient for a browser proof:
+
+- `POST /api/v1/materials`
+- `GET /api/v1/ontology`
+- `POST /api/v1/teaching-assets/prompts`
+- `GET /api/v1/teaching-assets`
+
+The frontend should make candidate state obvious and preserve evidence in
+compact text. A full graph canvas would be premature.
+
+## Recommendation
+
+- Use a text ingestion form.
+- Render candidate concepts as selectable options for asset prompt generation.
+- Show counts for concepts, edges, gaps, and prompts.
+- Show model verification guard in the generated prompt output.

+# Phase 9 Summary
+
+**Status:** Complete
+**Completed:** 2026-04-26
+
+## Delivered
+
+- Added material ingestion workspace to the web app.
+- Added ontology candidate summary with concept, edge, and gap counts.
+- Added candidate concept selector for teaching asset prompt generation.
+- Added asset type selector and prompt generation UI.
+- Rendered prompt text, model key, review state, evidence, and model-id
+  verification guard.
+- Added frontend asset test coverage for teaching asset API wiring.
+
+## Verification
+
+```powershell
+gofmt -w cmd internal
+go test ./...
+openspec validate frontend-mvp --strict
+```
+
+Additional smoke check:
+
+- Static app script includes material and teaching asset API wiring.
+- Material ingestion returned 4 concepts and 3 edges.
+- Teaching asset prompt generation returned `asset-prompt-1` with verification
+  guard enabled.
+
+## Deferred
+
+- Browser screenshot audit because Chrome DevTools MCP timed out.
+- Full ontology graph editor.
+- Real image generation.

+# Phase 9 Verification
+
+## Verdict
+
+PASS
+
+## Requirement Coverage
+
+- WEB-05: PASS. The web app includes material ingestion UI wired to the real
+  backend API.
+- WEB-06: PASS. The web app renders ontology candidate concept, edge, and gap
+  counts and candidate concept labels.
+- WEB-07: PASS. The web app can generate and inspect teaching asset prompt
+  candidates.
+- WEB-08: PASS. The MVP frontend includes loading, empty, and error states for
+  diagnostic, progress, material, and asset prompt flows.
+
+## Evidence
+
+- `go test ./...` passed.
+- `openspec validate frontend-mvp --strict` passed.
+- Live material ingestion and teaching asset prompt smoke passed.
+- Static app script contains material and teaching asset API integration.
+- Source files remain under 600 lines.
+
+## Residual Risk
+
+Chrome DevTools MCP timed out while opening the local page, so browser
+screenshot verification is still pending. HTTP/API smoke confirms the served
+assets and backend flows, but a visual pass should be repeated when the browser
+tool is responsive.
