#!/usr/bin/env python3
"""News summarizer — Nous map-reduce of scraped articles into brief/ticker/map.

Reads articles scraped within the last SUMMARY_WINDOW_MINUTES from the shared `articles` table,
maps them with Nous (per-article English fact blocks), reduces to one JSON
object (summary_en + ticker + map_items), and stores the brief in
`article_summaries` plus flagged rows in `news_items`. Tables live in the
EXISTING osint-db (alembic 003_news + 005_news_items, idempotent).

Everything is env-driven (12-factor). Secrets/config are resolved at the start
of each summarize_news() — env wins, else api_keys / app_settings:

  DB_HOST / DB_NAME / DB_USER / DB_PASSWORD / DB_PORT   PostgreSQL (osint-db)
  NOUS_API_KEY             Nous Portal key (else api_keys.name='NOUS_API_KEY')
  NOUS_BASE_URL            default https://inference-api.nousresearch.com/v1
  SUMMARY_MODEL            default Hermes-4.3-36B (else app_settings)
  BATCH_SIZE               articles per map-phase batch (default 50)
  SUMMARY_WINDOW_MINUTES   look-back window (default 15; SUMMARY_WINDOW_HOURS wins if set)
  NEWS_SUMMARIZE_FORCE     "1" to ignore the interval idempotency skip
  INCLUDE_FUTURES          "1" to prepend live futures prices (default 0)

The futures/markets coupling from the original pipeline is gated behind
INCLUDE_FUTURES and OFF by default — it is irrelevant to the OSINT dashboard
and pulled yfinance into the image. Re-enable by installing yfinance and
setting INCLUDE_FUTURES=1.

You are a precise, factual OSINT news processor. Your ONLY source of information is the articles provided below. Do NOT add external knowledge, assumptions, training data, or invented facts.

Write every field in English. Translate if the article is not English.

For EACH article in the batch:
1. Extract 2-4 key factual bullet points (who, what, when, where, numbers, quotes — stay very close to the text).
2. Location: country/city/region or Unknown. If you can estimate coordinates, emit them as numbers; otherwise omit.
3. Entities: list the key people, organizations, or governments mentioned (comma-separated, only names present in the text), else "None".
4. Category: pick one — politics, military/conflict, economy, technology, environment/disaster, health, crime, society, sport, other.
5. OSINT signal: if the article describes an event with geopolitical, security, military, economic, or disaster significance, say so in one short sentence. Otherwise write: "No notable OSINT signal."
6. Importance: critical (breaking geopolitical/military/disaster with immediate impact), high, medium, low, none.

If several articles cover the same story, add one short batch-level note at the end: "Batch theme: [one sentence]".

Output format — strictly one block per article:

Article 1:
- Fact bullet 1
- Fact bullet 2
- Location: ...
