+# MeMind News Engine MVP
+
+## Boundary
+
+- `memind-news-engine` owns collection, event clustering, ranking, and briefing candidates.
+- `Memind` consumes ranked candidates and owns page generation and delivery.
+- `memind_adm` owns source configuration, ranking policy editing, review, run monitoring, and publish controls.
+- The legacy `ops/` UI is not extended.
+
+## Current pipeline
+
+```text
+Memind SearXNG query groups
+  -> memind-news-engine HTTP API
+  -> event clustering by canonical URL and title similarity
+  -> deterministic rule score
+  -> optional structured LLM assessment
+  -> global score plus optional user-interest score
+  -> breaking-news override
+  -> category quotas and source diversity
+  -> ranked candidates in the existing briefing prompt
+  -> existing page generation, dedupe, image, and WeChat delivery guards
+```
+
+The first slice is deliberately deterministic. The model may provide the six semantic dimensions, but application code calculates the weighted score and owns final selection.
+
+## Score contract
+
+LLM assessment values are 0-10:
+
+```json
+{
+  "importance": 8,
+  "novelty": 9,
+  "impact": 8,
+  "credibility": 9,
+  "relevance": 8,
+  "actionability": 7,
+  "category": "ai_tech",
+  "reason": "A flagship model release changes capability and API economics."
+}
+```
+
+Semantic score weights are 25% importance, 20% impact, 15% novelty, 15% credibility, 15% relevance, and 10% actionability. When the LLM assessment is present, global score is 35% rule score plus 65% semantic score. When a user-interest score is present, final score is 70% global plus 30% personal.
+
+Breaking override is active when importance is at least 9, there are at least two distinct sources, and credibility is at least 8.
+
+## Runtime controls
+
+- `MEMIND_NEWS_ENGINE_DAILY_LIMIT`: selected event count, default `15`.
+- `MEMIND_NEWS_ENGINE_MINIMUM_SCORE`: minimum final score, default `0` during the observation phase.
+- `MEMIND_NEWS_ENGINE_URL`: independent service base URL; ranking is skipped when unset.
+- `MEMIND_NEWS_ENGINE_API_TOKEN`: service-to-service bearer token.
+- `MEMIND_NEWS_ENGINE_TIMEOUT_MS`: request timeout, default `5000`.
+
+## Next slice
+
+The engine repository now owns persistence migrations and the ranking API. Next work is the bounded LLM scoring worker, collection scheduler, and `memind_adm` management UI.
