Wave 6: Combat Intelligence Layer (honest free v1)

Net-new MMA/UFC vertical — fight-card discovery, tale-of-the-tape,
style-blend archetypes, ML + round-total odds, and a style-edge VERDICT
(a MODEL read, explicitly NOT a settled grade). Built to
specs/combat-intelligence.md.

Backend:
- combatAdapter: ESPN MMA scoreboard (date-pinned, free JSON) -> fight
  cards + tale-of-tape (record/weight class/rounds/ESPN athlete id);
  defensive parse (null on unknown shape, never throws); injectable
  fetchImpl + cache; pure normalizeCombatOdds (odds-api h2h/totals ->
  ML + round total, allow-listed books, best price). Number(null) guard.
- archetypeService: 6 pinned combat styles in a SEPARATE COMBAT_ARCHETYPES
  registry (FINISHER collides with soccer + its green trips the signal-
  green gate); classify('mma') blends range/tempo/outcome, honest-empty on
  thin data (no forced fallback); styleMatchup() honest verdict.
- oddsService: SPORT_KEYS.mma + MMA_MARKETS=['h2h','totals'] + SPORT_MARKETS
  (no spreads suffix). oddsNormalizer MARKET_MAP h2h/totals.
- config/sports.js + web mirror: mma.active=true (collectData stays false;
  NOT in the graded-props pipeline SPORT_CONFIG or snapshot/settle loop).
- routes/combat.js: GET /api/combat/:date + GET /api/fight/:id (public,
  cached, honest empty off-card) + Next proxies.

Frontend:
- FightCard: two-fighter tale-of-the-tape (initials monogram — no photos),
  GRAPPLER/STRIKER blend bars, discipline pedigree tags, shared
  ArchetypeBadge (sport="mma", unicode glyphs), CENTER VERDICT, ML +
  round-total real; method/round/KO = honest "data-limited", never
  fabricated. Self-hides on a non-two-fighter bout.
- /fight/[id] page (server wrapper + client), EmptyState off-season.
- MMA SportBadge token (#D4AF37); archetypes.js sport-aware resolution.

DEFERRED (per spec, NOT built): matchup-GRADE engine, method/round/props
board, combat settlement, ufcstats scraping.

Tests: +3 suites (31 tests) — combat archetype cross-file color/glyph
match, classify blends, styleMatchup honesty, adapter defensive parse +
odds normalize, FightCard honesty grep; extended oddsNormalizer +
sportMarkets. Full suite 253/253 green.
