JAGUAR v3.0 — Striker-Only. Stalker and Hunter removed. Pyramiding removed. v1.0 lost -29.3% across 5 trades. 4 of 5 had broken DSL (missing size field in state file). v2.0 fixes DSL state generation with wallet+size fields, reduces leverage to 7x, and focuses exclusively on STRIKER signals (violent FIRST_JUMP explosions, score 9+, volume 1.5x). DSL exit managed by plugin runtime via runtime.yaml.
