Improvements from a live-verified audit of the news/calendar pipeline: - Currency tagging: keyword matching now uses letter-boundary regexes and drops ambiguous "us "/"eu "/"uk " tokens — "versus" no longer tags headlines as USD (confirmed live false positive polluting the XAU/USD sentiment average). - Fetch caching: calendar events and headlines are cached class-level (10 min TTL, 60s retry after empty/failed fetch, lock-guarded for concurrent scans). Stops per-scan refetching that was tripping the Forex Factory rate limit; TTL stays under the 30-min pre-event buffer so the danger window can't go stale. - Surprise detection: EconomicEvent.surprise is computed from parsed actual vs forecast (handles %, K/M/B/T suffixes, negatives). A surprise print widens the post-release caution window to 45 min; inline releases keep the original 15 min. - Gold-aware sentiment: headlines are scored per currency, with monetary-policy keywords (hawkish/rate hike/tightening vs dovish/ rate cut/easing/stimulus) inverted for XAU — "hawkish Fed" headlines scored +1.0 for gold before, -1.0 now (verified on live feed). - New sentiment sources: Google News gold-focused query and CNBC Economy RSS (verified live; 40 → 74 unique headlines). Added cross-feed title dedup so syndicated stories count once. - events_today now buckets by UTC date (feed timestamps carry US- Eastern offsets); --json output includes news_description. - Removed dead NewsConfig.min_impact and unused HIGH_IMPACT_EVENTS. Tests: 142 passed (7 new covering boundary matching, surprise classification, post-event windows, cache reuse, gold inversion).
