Question 1

How does the Protection History Engine work?

Accepted Answer

Every time you capture a snapshot, the platform records all flagship scores locally with a timestamp. Trend charts, deltas, and progress tracking are computed from the recorded series.

Question 2

Where is my history stored?

Accepted Answer

In your browser only (localStorage). Nothing is sent to a server. Architecture is migration-ready for future authenticated accounts and cross-device sync.

Question 3

What if I have no recorded snapshots yet?

Accepted Answer

We render a 6-month deterministic backfill so the trend visualizations are meaningful immediately. Captured snapshots replace the backfill as soon as you have two or more.
