        The expert observed production use in which each work center's output
        capacity per hour and cost per hour provide an immediate planned-margin
        calculation.
      - >-
        The expert observed that after production completion, the user sees
        actual per-unit cost in real time from time-ticket data.
      - >-
        The expert observed that each work center is linked to one warehouse and
        the final dashboard compares margin by warehouse and work center.

        The expert confirmed direct applicability in M1_V1, M1_V2, M1_V3,
        M1_V4, M1_V5, M1_V6, and M1_V7.
    scope: >-
      Production use across M1_V1, M1_V2, M1_V3, M1_V4, M1_V5, M1_V6, and
      M1_V7; account identity, account type, observation date, and observation
      duration were not supplied.
    confidence: medium
    notes: >-
      User-provided observation preserved faithfully: each work center has
      output capacity per hour and cost per hour, making planned margin
      available immediately; after production is completed, the user sees real
      per-unit cost in real time from time tickets; each work center is linked
      to one warehouse; and the final comparison appears on a dashboard by
      warehouse and work center. The expert stated this was observed in
      production and selected all seven current vertical IDs. No exact date,
      period, named account, screenshot, recording, quantified result, or
      independent margin-formula validation was supplied. MCP corroborated the
      underlying mechanics but not the exact dashboard output.
