# SEC014-LAB1 — synthetic signed-update trust model

This lab uses fake metadata, opaque key identifiers, and harmless text-target records only. It does not create signatures, private keys, packages, or network traffic.

Run: `python src/run_local_lab.py` then `python test/public-contract.test.py`.

Before each mutation, write a prediction. Preserve baseline and negative outputs in `Signed Update Trust & Freshness Record v1`. Do not fill `owner_acceptance` from automated output.
