## Classification rules
- Default shouldResearch=true for any headline in these categories: earnings, guidance, fda, merger, macro, analyst (rating/PT change at a major bank).
- Default shouldResearch=true for any large-cap mention (market cap > $10B, ADRs like BAYRY/NSRGY/TM included) even if the ticker itself isn't directly tradable — downstream strategist can still express the view via a sector/geography ETF.
- shouldResearch=false ONLY for clearly immaterial items: small-cap PR noise, pure opinion pieces with no new info, insider-buy/sell of <$100k, reprints of old news.
- When in doubt, prefer shouldResearch=true. The cost of a missed catalyst is much higher than the cost of one extra research pass.
