Practice Calibration
Use this after attempting independent practice. These are calibration notes for the new cases, not answers to every original open-ended project. The module assessment retains its own scoring and evidence requirements.
Prerequisite calibration
No. Process startup is weaker than a usable end-to-end service. Repair deployment/readiness and dependency checks.
A ready answer includes the example or trace requested in the entry check. A memorized term is not sufficient. Repair the named earlier skill, then change the example and explain it without this page.
Case A
Required identity/setup is missing and the artifact bytes are not pinned/verified. Supply a least-privilege documented identity path and exact artifact provenance; never publish credentials.
Full practice credit requires the result, assumptions and an explanation of the tempting error. A correctly guessed conclusion without those elements is only partial evidence.
Case B
Compatibility of the old application with current data/schema and preservation of accepted writes. Image rollback alone does not reverse a migration.
The key judgment is which guarantee survives the changed condition. Do not transfer a result from the first case without checking that condition.
Experiment calibration
Run the real capstone release from a clean documented environment with access controls, migration verification, failed-deploy recovery and scoped teardown. Reuse S09 mechanisms, but retain this capstone's actual results.
A usable record links the hypothesis to the actual input, observation and interpretation. The negative control must fail for the intended reason, and the repaired setup must pass the relevant check again. Report unexpected outcomes rather than altering the hypothesis afterward. Explicitly state the model, environment and untested boundary; passing a small fixture never proves every deployment behavior.
Recheck
Explain a fresh variant without the key. Retain the original error, repair, help received and delayed result in the existing evidence packet. Self-calibration is not an independent reviewer sign-off or a learner-pilot result. For retrieval-question explanations, use quiz calibration only after attempting the quiz.
