Sock changes unit economics.
A physical interpretation can introduce manufacturing, sizing, inventory, packaging, shipping, returns and product-quality questions. A symbolic interpretation changes those dependencies rather than erasing the need for a concrete deliverable.
Story changes creative throughput.
Original narrative work creates authoring, editing, rights, tone, archive and repetition questions. A story card or prompt has a different workload than episodic fiction.
Daily changes capacity.
A daily expectation can describe publishing, use, reveal or delivery. Those are not equivalent. Define the cadence before estimating workload or promising continuity.
