Youth and club preseason matches are excluded. Each appearance uses reported minutes, goals and assists with the same weights. Early windows contain only matches played so far.

  "eventPolicy": "Each source event has an explicit pricingClass. A squad title is credited on the verified title date even if the player does not appear in the clincher; the article identifies this context. The same title class uses the same rate across seasons. Combined championship-and-award reports receive only the title factor. Individual Kopa and Golden Boy awards are separate honours and use the same youth-award rate. Match scoring records receive no extra premium because goals already enter match performance.",
  "injuryRecovery": "Apply one availability discount for an officially reported injury. Further reports do not stack while the discount is active. Reverse it using 1 / 0.95 on the next observed appearance after that report. This means return to play, not a claim of full recovery.",
  "execution": "Apply match performance, then dated event factors, then observed reader attention, rounding to cents after each step. Contributions add exactly to the daily closing-price change. No random price noise, synthetic intraday points, delayed drift or arbitrary daily cap. Missing news does not establish no news occurred.",
  "timeBasis": "Match calendar dates use the venue/source date; Wikimedia observations use UTC days. These are daily snapshots, not an intraday timeline.",
  "score": "An internal descriptive score supports the existing tier badge: 70% normalized blended match contribution, 20% cumulative event factor, 10% observed reader attention. Missing attention redistributes the descriptive weights. These scores do not target or drive the model price."
