/**
 * Timing-review read endpoint (#158).
 *
 * GET /api/curriculum/[playerId]/timing-review
 *
 * Returns every flagged (Tier-1/Tier-2) attempt across the player's recent
 * session window plus the pace assessment, so the /review-timings page can show
 * all unusual timings at the player level (a parent need not know which session
 * to open). The estimate numbers come from `getPaceAssessment` (the single pace
 * producer) via `getTimingReviewData` — this route never computes its own.
 *
 * Gated on `repair-data` (parent or teacher-present) to match the write side:
 * the whole page is a repair tool, and every affordance on it requires that
 * capability.
