First four-format set: ~552 odds entries across Hobby (141), Breaker (136), Value (138), and Mega (137). Added the Breaker box config (12 cards per pack, 1 pack per box, 8 boxes per case, 3 autographs guaranteed); top-level keys follow the lowercase convention (hobby/breaker/value/mega) used by box_config and every other multi-format set.
Format exclusivity by key absence: Geometric Refractor ladders (base + all autograph subsets) are Breaker-only; RayWave and X-Fractor are Value-only; Mini Diamonds is Mega-only; the classic inserts plus Prism/Negative/Sonar/UFC Glove/OctaFractor/FrozenFractor are Hobby-only. Breaker has no plain Base odds — its packs are filled by the Geometric ladder and autos. Per-pack hit rates are highest in Breaker (3 autos in a single 12-card pack), as expected.
Parser note: the sheet contains per-pack multiples ("5:1", "4:1", "2:1", "1:1"). The shared parseOddsToDenom utility already handles generic A:B ratios (no extension needed) — verified 5:1 → 5.0/pack, 1:1 → 1.0, no NaN in any format.
Source normalizations (applied before attach): "Geomtric" → "Geometric", "Superfractors" → "Superfractor", "FrozenFractors(#'d ...)" → "FrozenFractor", "X-Fractors" → "X-Fractor". Key prefixes aligned to DB subset names: "All-Action" → "All Action", "Allen & Ginter" → "Allen and Ginter", "Kings & Queens" → "Kings and Queens", "Base Autograph Variations" → "Base Cards Autograph Variations". All "2025 Chrome UFC Buyback" rows deliberately excluded (no checklist entries in this set).
Known data gaps: "UFC Debut Patch Autographs" odds keys are attached but the subset has no checklist entries yet, so they display in the odds tables without entering the calculator pool or hardest-pull rankings. Hidden Gems Citrine/Alexandrite/Painite parallels likewise have odds but no parallel rows.
