Iteration 15 — Full-Grid k_v: Proposals Corroborated Grid-Wide SUPPORTING EVIDENCE

What happened, in plain words: before the operator rules on the pending status proposals, the loop attacked its own drafts: it extended the regime counting from the two flagship pairs to every combination on both markets (35 tables: 20 crypto, 15 forex) and asked whether the drafted features keep their records elsewhere. They do, emphatically: bar_petrosian_fd is orthogonal in all 10 regimes on all 20 crypto combos; the other three drafts average 99%+ with a single 9-of-10 blemish each. The counter itself also passed an unplanned robustness check — it reads nearly identically across combos where it should (the engineered features) and varies exactly where markets genuinely differ (the volume family). Bonus: 70 FRAGILE-candidate sightings across the grid, four-fifths on forex — confirming FRAGILE is a real, mostly-forex phenomenon. (The literature sweep stayed blocked — search still unavailable, third attempt; nothing unverified admitted.)
