🦅 VULTURE v4.0.0 — Long-Tail Momentum Rider (senpi_runtime_helpers)

v2 → v3 architectural rewrite. v2.x was a full-agency scanner that called create_position directly and tracked state in Python. v3.0 flips to the standard senpi-trading-runtime plugin pattern: producer emits signals, runtime owns execution + state.

What changed structurally:

• vulture-producer.py (NEW) replaces vulture-scanner.py (DELETED). Pure producer — no execution, no counters, no cooldowns, no dynamic-slot bookkeeping.
• runtime.yaml is now runtime-native: external_scanner + LLM-pass-through gate + native risk.guard_rails + DSL preset with FEE_OPTIMIZED_LIMIT.
• Trade chain DB now emits LIFECYCLE_RUNTIME_STARTED → DECISION_EXECUTED → ACTION_RESULT → DSL_CREATED → DSL_CLOSED for every trade. Per-trade telemetry is restored.
• The cfg.set_cooldown silent crash is structurally impossible in v3.0 (cooldowns are runtime-managed, not Python-managed).

What's preserved from v2.4:

• Asset universe (25+ small/mid-cap Hyperliquid perps)
• LONG_TAIL_MOMENTUM scoring (SM concentration tier + 4h momentum + 15m velocity + 1h acceleration + 4h continuation + trader depth + regime alignment + persistence)
• Hard gates: SM ≥3% / 15 traders, 4h aligned ≥1%, 1h aligned ≥0.1% (the v2.4 fix), 15m velocity ≥0.3
• Conviction-scaled leverage (3x cautious / 5x conviction / 7x apex)
• DSL Phase 2 ladder (15/20, 30/60, 40/75, 75/75, 100/85, 150/92) — proved correct on the live ZEC trade
• 90-min dead_weight_cut, 180-min weak_peak_cut, 7-day hard_timeout
• 38% WR target with 6.15x profit factor
