1
00:00:00.000 --> 00:00:05.000
BUILD 026. A CLEAN TABLE CAN HIDE. Messy history still matters.

2
00:00:05.000 --> 00:00:10.000
RAW. PRESERVE THE SOURCE. Keep collection, time, owner, and permitted use.

3
00:00:10.000 --> 00:00:15.000
NORMALIZE. STANDARDIZE—DO NOT ERASE. Missingness and conflict remain signals.

4
00:00:15.000 --> 00:00:20.000
REVIEW. ASK WHO IS MISSING. Large coverage can still exclude.

5
00:00:20.000 --> 00:00:25.000
TRACE. MAKE TRANSFORMATIONS REVERSIBLE. Every field needs a path home.

6
00:00:25.000 --> 00:00:30.000
DECISION FITNESS. DO NOT CLEAN AWAY WARNINGS. Visible limits make data usable.
