# OPS016-LAB1 — Target DDL → Runtime Projection

Use only the supplied synthetic fixtures. For each case, construct one row of DDL Runtime Projection Reconciliation Record v1. Keep target definition and runtime observation separate, record observation source and visibility scope, then classify the relationship as semantic match, expected difference, drift, or unknown.

The lab is intentionally offline. Do not connect to any database, request credentials, or infer production state. A raw text difference is not sufficient to call drift, and restricted visibility must remain UNKNOWN until evidence closes it.
