| Disclosure Hub | par | Hub links the disclosure surfaces, but needs more cross-surface summaries. |
| Insiders | par | Convergence becomes stronger as 13F coverage broadens. |
| News | par | Needs more issuer-level receipts and source grouping. |
| Capital Web | strong | Add wider anchor coverage after current filer roster stabilizes. |
| Sector Rankings | par | Ranking logic is useful, but drill-down context is still light. |
| Watchlist | par | Needs more daily change explanations per ticker. |
| Portfolio | par | Per-holding Score table exists, but price/P&L attribution can be deeper. |
| Screener | thin | Default result density depends on cold score dataset latency. |
