Evidence Preservation

Snapshots before clean-up.

Overview

Evidence Preservation: a practical look at the patterns that work and the trade-offs that matter.

Snapshots before clean-up. The full picture, in three sections.

The approach

Each pattern has a context where it wins. Understand the context before applying.

Tooling matters. Pick tools that fit the workflow; don't force-fit.

Why this compounds

Healthy practice compounds year over year. Year 1 lays the foundation.

Year 2 and beyond: practices become habits; quality improves measurably.
