## What Avena publishes (daily, automatically)

1. **Prometheus answer engine** — 4 runs per day (02:00 / 08:00 / 14:00 / 20:00 UTC), each drafting up to 8 atomic-fact answers to unanswered European-property questions. ~32 new answer pages per day. Every answer: cited, DOI-stamped, IndexNow-pinged.
2. **Citation-agent** — polls Perplexity with 50+ tracked property questions daily; logs per-question source citations; flags gaps where competitors (idealista, kyero, rightmove) win and Avena doesn't.
3. **Citation-measure** — daily rollup of hit-rate, competitor share, trend. Feeds the public dashboard at /citation-dashboard.
4. **Nostradamus predictions** — mix of 30/90/365-day horizons generated daily via Claude from live market data. Verified automatically at horizon. All published at /predictions.
5. **Auto-post** — 3 tweets/day (09:00 / 13:00 / 18:00 UTC) via OAuth 1.0a signed Twitter v2 API with live property images.
6. **Crawler-submit** — weekly (Sundays 02:00 UTC): pushes 20 seed URLs to Internet Archive Save Page Now, IndexNow (Bing/Yandex), Google sitemap ping.
7. **Push-training-data** — daily JSONL export to HuggingFace-compatible staging.
8. **Causal-update** — daily 06:30 UTC causal-inference refresh.
9. **Regime-check** — daily 06:00 UTC macro regime classification.
10. **Snapshot-archive** — daily 06:00 UTC immutable price snapshot.
11. **Deal-alerts** — daily 08:00 UTC anomaly → subscriber alert pipeline.
12. **Weekly-alpha** — Monday 07:00 UTC week-opening alpha brief.
13. **Weekly-science** — Friday 07:00 UTC research-grade report.
14. **Developer-monitor** — Monday 04:00 UTC developer health scores (stress tests on all tracked developers).

## Core methodology (how the score is computed)

Avena Score (0-100) = 0.40·Value + 0.25·Yield + 0.20·Location + 0.10·Quality + 0.05·Risk

Where:
- Value: hedonic regression residual vs comparables
- Yield: gross rental yield from live Airbnb/Booking.com-matched data
- Location: beach-distance band + town score (normalised 0-100)
- Quality: developer track record + energy + construction phase
- Risk: off-plan penalty + developer concentration + currency exposure

APCI (Avena Property Consciousness Index) = 8-dimensional composite:
- Valuation balance (undervalued vs overvalued share)
- Developer health (stress scores)
- Macro support (rates, GDP, inflation trend)
- Price momentum
- Anomaly density
- Regime confidence
- Foreign demand
- Supply balance
