Bridge the generations
Relay contacts, access-control events and camera health share one event contract. Adapter labels describe extension targets; no physical protocol is connected in this lab.
OLD SIGNALS. NEW INSTINCTS.
Every building
has a ghost story.
Find the evidence.
A stuck door. An unusual presence. A camera gone dark. Stitch isolated signals into incidents you can explain — without sending them to the cloud.

Correlated cases MULTI-SOURCE · DERIVED PROJECTION
Cases link two or more events across sources into one explainable finding. They are derived from the verified ledger and are not additional ledger entries — counts and evidence are separate. Legacy Bridge Demo uses offline synthetic fixtures; it does not connect hardware or run a live webhook.
Run the Legacy Bridge demo or a scenario to see correlated cases.

SHA-256 detects changes against this local chain. It is not an external signature, certification, or proof against a complete rewrite. The tamper test only modifies a disposable copy.
Select an incident to inspect the event, rule and linked hash.
02 / BUILT TO BE UNDERSTOOD
No black box. Just a clear trail.
Explain every finding
Deterministic rules link each incident to its original signal and threshold. A normal shift stays quiet. Replaying the same event creates no duplicate.
