Sequence 156 — Meridian applied lab - execute, vary and prove

Context: Chapter 8 - Data Integration and Interoperability | Applied Lab
Source: CDMP Master Execution Manual

When / purpose

Perform the Chapter 8 work independently enough that the output is evidence of understanding rather than tutorial completion.

What you should learn

• Follow the business problem, not a click path.
• Explain every technology action that affects the result.
• Vary or break one fact when the lab design calls for it.
• Preserve before/after evidence and reasoning.

What to read / study

Use the source-grounded Chapter 8 Applied Lab guide only once available; do not substitute a generic web lab. Save evidence and journal entries in the Meridian evidence area; no real sensitive data.

Do this in order

1. Perform the lab in the prescribed order.
2. Annotate decisions and assumptions as you work.
3. Explain any supplied script/template before running it and change a learning-critical part yourself.
4. Capture required evidence.
5. Rebuild or repeat the critical portion without step-by-step prompting.

Meridian application

Expected outputs: Staging tables; SQL/Python transforms; mapping spec; lineage evidence.

Create / save

Staging tables; SQL/Python transforms; mapping spec; lineage evidence + evidence + independent reconstruction proof.

Stop / boundary

Stay inside the current source/skill boundary. Do not pre-learn later chapters or engineering depth.

Completion gate

You can reproduce the critical result and explain how it demonstrates Chapter 8 rather than merely showing a finished artifact.
