// Geopolitical classification for prediction-market titles (Phase 2 / #5525,
// #5733). WorldMonitor's identity is geopolitical intelligence, so the market
// bet-family is split into a dedicated geopolitical slice (long horizon, top
// ensemble priority) and a general slice — and the split is driven by the
// market TEXT, deliberately NOT by the bootstrap feed's geopolitical/tech/
// finance pools.
//
// Originally that was a workaround: the pools were near-duplicates and the
// "geopolitical" pool was dominated by crypto/finance titles. The producer now
// assigns exactly one primary pool per market (see _prediction-classify.mjs,
// which reuses isGeopoliticalMarket below as its title signal), so the labels
// are trustworthy — but the bet families still classify from the title, for two
// reasons that outlive the fix:
//   1. the feed's 3h TTL means a pre-fix payload can still be served for hours
//      after a deploy, and the partition must not depend on when Redis last
//      refreshed;
//   2. the two families read the UNION of all three pools anyway (they need
//      every market, partitioned by their own horizon), so pool membership is
//      not the axis they split on.
//
// THE TWO CLASSIFICATIONS ARE NOT IDENTICAL, and that is deliberate. The
// producer treats a market as geopolitical when the TITLE matches (this
// predicate) OR the venue tags do; the bet families use the title signal only.
// So a market that is geopolitical purely by tag — "Will AfD win the most seats
// in the 2026 Berlin state elections?" (tags: elections/global-elections/
// world-elections), or a bilateral trade-deal line tagged `geopolitics` — lands
// in the producer's geopolitical POOL but in the GENERAL bet family, not the
// long-horizon geo one. That is an accepted consequence of this predicate being
// precision-first (a false geo tag would steal a flagship ensemble slot, which
// is worse than a missed one), not a bug to fix by importing the tag rescue.
// What the shared predicate does guarantee is that the two can never disagree
// about a TITLE — the axis both actually key on.
//
// Precision over recall: a FALSE geopolitical tag pollutes the flagship slice
// (a company/crypto market stealing a geo ensemble slot), which is worse than a
// missed one, so the matcher keys on unambiguous conflict/statecraft terms and
// high-salience actors — never on bare country names ("Chinese AI model" is
// tech, "Korea" alone is ambiguous) and never on bare "election"/"strike"
// (company boards hold elections; options have strike prices).
//
// Weak terms (war, sanctions, uranium, occupation, leadership change) only
// fire with a high-salience actor/placename co-occurrence so corporate "price
// war", "uranium miner IPO", labor "occupation", and "CEO leadership change"
// stay non-geo.

// Unambiguous conflict / statecraft vocabulary. Word-boundaried so "war" does
// not fire alone (see GEO_WEAK) and "strike" is only matched in explicit
// military compounds, never alone (no "strike price" false positive).
