🐻‍❄️ POLAR v5.0.0 — ETH Alpha Hunter (senpi_runtime_helpers)

Best gross trader in the fleet. Single asset. Maximum conviction.

v3 → v4 architectural rewrite. v3.x was a full-agency scanner that called create_position directly and tracked state in Python. v4.0 flips to the standard senpi-trading-runtime plugin pattern: producer emits signals, runtime owns execution + state.

What changed structurally:

• polar-producer.py (NEW) replaces polar-scanner.py (DELETED). Pure producer — no execution, no counters, no cooldowns, no resting-order guards.
• 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 emits LIFECYCLE_RUNTIME_STARTED → DECISION_EXECUTED → ACTION_RESULT → DSL_CREATED → DSL_CLOSED for every trade. Per-trade telemetry is restored.
• The set_cooldown / load_tc Python state crashes from the legacy scanner pattern are structurally impossible in v4.0+ (cooldowns are runtime-managed).
