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.

**AI routing** in the [[pointsav-overview|PointSav]] platform is the mechanism by which [[service-slm|`service-slm`]] — the [[doorman-protocol|Doorman]] — mediates every request that involves a language model, whether the model runs locally on the customer's hardware, on a burst compute provider, or on an external API. The routing design treats the boundary between customer-controlled infrastructure and external compute as a one-directional filter: before any text leaves the customer's private network, the payload passes through a local Small Language Model that sanitizes sensitive information, strips location identifiers, and masks Personally Identifiable Information (PII). Only the sanitized prompt — containing the mathematical structure of the request but not the customer's private data — routes to external compute. When the external model returns a result, the router re-hydrates the response with the correct internal context before delivering it to the operator. The external model never holds the actual structured records from the customer's ledger.
