The core software
The wearable is not the whole company.
The wearable, phone tools and Site Mode are different entry points into the same core: the Peoples Defence Evidence Layer.
Architecture
Inputs → Evidence Layer → incident record.
What exists in the prototype direction
Evidence integrity and event organisation.
Timestamped events
The software direction is built around giving incident events a clear time and sequence.
Hash-chain integrity
Prototype work includes cryptographic hashing so evidence changes can be detected rather than silently ignored.
Incident Timeline
Media, triggers and relevant events can be organised into one clearer incident view.
Current technical stack
Built to be testable before it is perfect.
Current prototype work has included a FastAPI backend, database/event handling, real-time WebSocket workflows and a web dashboard. These are engineering implementation choices, not promises that the final production architecture is frozen.
Why one layer matters
New hardware does not require a new company every time.
If the Evidence Layer is the centre, the company can support a wearable today, a phone trigger during testing, connected site cameras for organisations, and later Peoples Defence-ready hardware without fragmenting the experience into unrelated products.
