Phase 10 Plan 03: Knowledge Base Portal Page Summary

Knowledge Base management UI with drag-and-drop upload, URL/YouTube ingest, live processing status polling, and RBAC-gated delete/re-index actions

Performance

• Duration: ~22 min
• Started: 2026-03-26T15:00:00Z
• Completed: 2026-03-26T15:22:53Z
• Tasks: 2 (1 auto + 1 checkpoint pre-approved)
• Files modified: 10

Accomplishments

• Full Knowledge Base page at /knowledge-base with document list, file upload dialog, and URL ingest dialog
• Live polling of document status — query refetches every 5s while any document has status=processing, stops when all are ready or error
• RBAC enforced: customer_operator sees the document list (read-only); upload and delete buttons only appear for admins
• i18n translations added for all KB strings in English, Spanish, and Portuguese
• Portal builds successfully with /knowledge-base route in output

Task Commits

1. Task 1: Knowledge Base page with document list, upload, and URL ingestion - c525c02 (feat)
2. Task 2: Human verification - pre-approved checkpoint, no commit required

Files Created/Modified

• packages/portal/app/(dashboard)/knowledge-base/page.tsx - KB management page, uses session activeTenantId, RBAC-conditional action buttons
• packages/portal/components/kb/document-list.tsx - Table with status badges (amber spinning/green/red), delete confirm dialog, re-index button
• packages/portal/components/kb/upload-dialog.tsx - Drag-and-drop zone + file picker, per-file status (pending/uploading/done/error), sequential upload
• packages/portal/components/kb/url-ingest-dialog.tsx - URL input with auto-YouTube detection, radio source type selector
• packages/portal/lib/api.ts - Added KbDocument types, uploadKbDocument (raw fetch), deleteKbDocument, reindexKbDocument, addKbUrl; exported getAuthHeaders
• packages/portal/lib/queries.ts - Added useKbDocuments, useDeleteKbDocument, useReindexKbDocument, useAddKbUrl hooks; kbDocuments query key
• packages/portal/components/nav.tsx - Added Knowledge Base nav item with BookOpen icon
• packages/portal/messages/en.json - KB translations (nav.knowledgeBase + full kb.* namespace)
• packages/portal/messages/es.json - Spanish KB translations
• packages/portal/messages/pt.json - Portuguese KB translations

Decisions Made

• getAuthHeaders() exported: multipart/form-data uploads cannot use the standard apiFetch wrapper (which always sets Content-Type: application/json overriding the browser's multipart boundary). Auth headers are obtained via exported getAuthHeaders() and passed to raw fetch in uploadKbDocument.
• CirclePlay instead of Youtube icon: lucide-react v1.0.1 does not export a Youtube icon. Used CirclePlay (red) as YouTube visual indicator.
• Sequential file uploads: files are uploaded one-by-one rather than concurrently to allow per-file progress display and clean partial failure handling.

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Youtube icon not available in lucide-react v1.0.1

• Found during: Task 1 (build verification)
• Issue: Youtube icon exported in newer lucide-react versions but not v1.0.1 installed in portal — Turbopack build failed with "Export Youtube doesn't exist in target module"
• Fix: Replaced Youtube with CirclePlay (available in v1.0.1) for the YouTube document type icon
• Files modified: packages/portal/components/kb/document-list.tsx
• Verification: Portal build passed with /knowledge-base in output
• Committed in: c525c02 (Task 1 commit)

---

Total deviations: 1 auto-fixed (Rule 1 - icon version mismatch) Impact on plan: Minor visual change only — CirclePlay with red color still clearly indicates YouTube content.

Issues Encountered

None beyond the icon version fix above.

User Setup Required

None - no external service configuration required. KB backend was set up in Plan 10-01.

Next Phase Readiness

• /knowledge-base portal page fully functional
• CAP-03 requirement complete
• KB documents can now be managed via the portal UI; agents with knowledge_base_search tool will use indexed content from these documents
