PointSav Documentation

The engineering library for the PointSav platform — operating systems and services for regulated businesses that own their data, their AI, and their record-keeping outright. Where the monorepo holds the code, this wiki holds the reasoning: architecture, services, security, and the governance commitments that bind future development.

### The collector's exposure

Two further properties of the collector are relevant to a security reading. Its own source comment
attributes its choice to bind to `0.0.0.0` — all interfaces, rather than loopback — to accepting
mesh traffic over the platform's WireGuard network, on a port taken from the environment with a
default of 8081. Its CORS configuration permits any origin (`allow_any_origin`).
