The Discuss button on news cards was producing one-shot replies because the model got the whole trafilatura blob dropped into history with a canned "summarize and discuss this article" prompt — no length guard, no prep, no invitation to converse. Large articles got silently truncated by Ollama; small articles got a tepid reply. This reworks discuss_article around a three-layer cache: context_prepared → content_full → fresh trafilatura fetch First click on a small article fetches once, writes through to both caches, and passes the body straight into the synthetic read_article tool-result. First click on a large article additionally runs a parallel map step (services/article_context.py) that chunks the body on paragraph boundaries, summarizes each ~8k chunk to ~300 words of dense factual prose via the background model, and concatenates the summaries under section headers — all pinned to num_ctx=16384 so the map step doesn't itself fall victim to silent truncation. Repeat clicks on either path skip straight to the chat turn. The canned summary prompt is replaced with a conversational seed that invites the user into an actual discussion rather than a one-shot synopsis, matching the goal of "have a conversation about an article, not just read it." discuss_topic is intentionally left untouched — it's the multi-article aggregation path and needs a separate rework. Follow-up task will decide whether to retire it or rework it on the cached-context approach. Closes task #106. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
