Carry the ready result into Lua

Add a reusable source file that returns a receipt for ready jobs.

YOUR TASK

Make this happen

3 steps

  1. Add a receipt script node after ready and load scripts/receipt.lua. Read envelope.ready.jobId and envelope.ready.status from the predecessor envelope.

  2. Keep the working capabilities from the previous lesson and connect the new pieces to the same solution.

  3. Check the complete solution, then inspect any unmet requirements.

Start in scripts/receipt.lua, then choose Check solution.

This step starts with the earlier solution and one new challenge. Each lesson keeps its own draft.
