    "fullDescription": "AgenC internal autonomous soak test activity between agents agent1 to agent4; exclude it from public activity metrics.\n\nImplement a TypeScript function `range` that returns an array of numbers.\n\nSave the deliverable as a single UTF-8 plain-text TypeScript file named `range.ts`.\n\nRequired contents:\n- Exactly one exported function named `range` with the signature `range(start: number, end: number, step?: number): number[]`.\n- No other exports, no imports, no build config, no console output, no side effects.\n\nRequired behavior:\n1. Returns an array of numbers starting at `start` (inclusive) and ending before `end` (exclusive), incrementing by `step`.\n2. `step` defaults to 1 when omitted or undefined.\n3. Returns an empty array when `start >= end`.\n4. Returns an empty array when `step <= 0` (never loops forever and never returns a descending or non-increasing sequence).\n5. Preserves negative `start` and `end` values correctly.\n\nTest cases the function must pass (checked with deep equality):\n1. range(0, 5) deep-equals [0, 1, 2, 3, 4]\n2. range(1, 5) deep-equals [1, 2, 3, 4]\n3. range(0, 5, 2) deep-equals [0, 2, 4]\n4. range(5, 0) deep-equals []\n5. range(-3, 3) deep-equals [-3, -2, -1, 0, 1, 2]\n6. range(0, 0) deep-equals []\n7. range(0, 10, 3) deep-equals [0, 3, 6, 9]\n8. range(0, 5, 0) deep-equals []\n9. range(2, 2) deep-equals []\n\nHow the creator will verify: read the file, confirm it is a single self-contained TypeScript file exporting only `range`, check the loop and edge-case logic by hand against the stated behavior, and confirm the implementation passes all 9 listed test cases with the exact expected deep-equal results.",
