Idea quality pipeline, web UI features, academic paper

- Tighten idea extraction prompts (1-4 ideas, no sub-features) reducing
  1,907 ideas to 468 across 434 drafts (78% reduction)
- Add embedding-based dedup (ietf dedup-ideas) for same-draft similarity
- Add novelty scoring (ietf ideas score) and filtering (ietf ideas filter)
  using Claude to rate ideas 1-5, removing 49 generic building blocks
- Final count: 419 high-quality ideas (avg 1.1/draft)
- Web UI: gap explorer with live draft generation and pre-generated demos
- Web UI: D3.js author collaboration network (498 nodes, 1142 edges,
  68 clusters, org filtering, interactive zoom/pan)
- Academic paper: 15-page LaTeX workshop paper analyzing the 434-draft
  AI agent standards landscape
- Save improvement ideas backlog to data/reports/improvement-ideas.md

+### 2026-03-06 CODER — Interactive D3.js Author Network Visualization
+
+**What**: Replaced the Plotly spring-layout co-authorship graph on `/authors` with a full D3.js v7 force-directed network. Added enriched data layer (`get_author_network_full`) with avg draft scores per author, connected-component cluster detection (68 clusters found), and a new `/api/authors/network` JSON endpoint. Template now includes: interactive D3 force graph with zoom/pan/drag, org filter dropdown, cluster highlighting with zoom-to-fit, hover tooltips showing author details + draft list, click-to-navigate, plus the existing Plotly org bar chart, cross-org collaboration chart, sortable authors table (now top 50), and org stats sidebar.
+**Why**: The Plotly spring layout was static and limited. D3 force simulation gives true interactivity -- draggable nodes, smooth zoom, hover/click interactions -- which makes the collaboration patterns much more explorable. Cluster detection reveals the structure (one giant 165-member cluster dominated by Huawei/China Telecom, plus 67 smaller groups).
+**Result**: 498 nodes, 1142 edges, 68 clusters rendered interactively. Org color coding, size-by-draft-count, label-on-hover all working. Three files changed: `src/webui/data.py` (new `get_author_network_full`), `src/webui/app.py` (updated route + new API endpoint), `src/webui/templates/authors.html` (full rewrite with D3).
