Sequence 297 — Schema-drift integration incident
Context: Cross-Chapter Integration & Capstones | Capstone / Integration
Source: CDMP Master Execution Manual
When / purpose
Connect representation change to integration and metadata/quality implications.
What you should learn
- Source changes can break downstream assumptions.
- Lineage/mapping context is needed to diagnose impact.
What to read / study
| Priority | Resource | Use now | Stop point |
|---|---|---|---|
| MUST | Cross-Chapter Capstone & Incident Roadmap | Use only the capstone/checkpoint named by this card. | Do not pull future chapter controls into earlier checkpoints. |
| REFERENCE | Meridian Casebook | Use canonical systems/roles/incidents. | No new company facts without documenting them. |
Do this in order
- Change a working-copy source column/format.
- Run the bounded integration process.
- Observe failure or changed output.
- Repair the mapping/process and record the impact.
Meridian application
Reuse the actual Meridian artifacts created in prior chapters; the capstone should integrate, not restart.
Create / save
Schema-drift incident evidence.
Stop / boundary
Use only chapters already completed at this point. Do not solve the incident with knowledge from future chapters.
Completion gate
You can trace source change -> integration impact -> repair and name which later metadata/quality artifacts should capture it.
