Radar render dashboard

Render the dashboard (README.md)

README.md is what GitHub renders on the repo home page — it IS the radar's output surface. It is fully derived from TRENDS.md; regenerate it from scratch on every run, never patch it. Design goal: one screen, everything clickable.

Layout (exactly these blocks, in this order)

1. Title — # AI Radar.
2. Badge row — four shields.io static badges, style flat-square: trends-<total>-3266ad, accelerating-<n>-e8590c, watchlist-<queue count>-6c757d, updated-<YYYY--MM--DD>-2f9e44 (escape - in dates as --).
3. Intro line — one sentence: what the radar tracks, for whom, and that the page is generated from TRENDS.md.
4. Digest — **Since last scan (YYYY-MM-DD):** + 3–4 bullets MAX, in priority order: stage moves, queue promotions/drops, strongest new evidence. Every bullet must contain at least one link (trend anchor or evidence URL). If nothing changed: one bullet, "Quiet scan — no ledger changes."
5. Pinned topics (⭐) — ## ⭐ Pinned topics then a table of ONLY the trends with pinned: true, same columns as the main table. These are the curator's standing-watch axes; they appear here AND in the main table (where their trend label is prefixed with ⭐). Sort by last_evidence descending.
6. Trends section — stage strip on one line (🌱 n · 📈 n · 🚀 n · 🌊 n · 🏔 n · 📉 n · 💤 n), then ONE table | trend | stage | latest signal | with ALL trends (pinned included, prefix their label with ⭐), sorted accelerating → emerging → seed → mainstreaming → saturated → declining → dormant, then by last_evidence descending:
   • trend = short label (≤5 words; reuse previous README labels for stability) linking to the trend's anchor in TRENDS.md (see anchor rule); prefix with ⭐ when pinned: true.
   • stage = emoji + word.
   • latest signal = the last_evidence date linking to the evidence URL whose date equals last_evidence (first match in list order); if none matches, link the top evidence item.
7. Worth studying — the study_shelf section of TRENDS.md, newest first, up to 12 bullets: [name](url) — one line of why (the shelf persists ~20 picks / 30 days so a reader away for a couple of weeks can still catch up).
8. Community pulse — ## Community pulse (Phase 3): up to 5 bullets distilled from the latest radar-pulse intake — non-evidence, link-only, NEVER naming individuals (link the thread/profile, summarise). If no pulse data yet, one line: "No community pulse sampled yet." This section is clearly marked as unverified sentiment, separate from the verified trend table.
9. Output map — one line of links: TRENDS.md, watchlist (queue count) → TRENDS.md#observation_queue, reports/ + newest daily, newest weekly ("weekly: none yet" if absent), AGENTS.md, SOURCES.md.

Anchor rule (GitHub heading slugs)

For a heading ### [id: slug-NNN] Title, the anchor is: lowercase the whole heading text, delete every character that is not a letter, digit, space or hyphen (no replacement — Prefill/decode → prefilldecode), then replace spaces with hyphens. Example: ### [id: pd-disagg-002] Prefill/decode disaggregation as the standard LLM serving architecture → TRENDS.md#id-pd-disagg-002-prefilldecode-disaggregation-as-the-standard-llm-serving-architecture. Anchors are recomputed at every render, so title edits stay in sync.

Checks before commit

• Badge counts = stage-strip counts = table row count = number of ### [id: blocks in TRENDS.md.
• Every table date equals that trend's last_evidence exactly; every row has two working relative/absolute links.
• No Mermaid, no images besides the badges, no sections beyond the blocks above.
• Pinned-topics table contains exactly the pinned: true trends; every pinned trend is ⭐-prefixed in the main table too.
• Community-pulse items are link-only and name no individuals.
• Commit README.md together with the TRENDS.md change that triggered it.
