FlowShield.

Predictive agent security and causal authorization exploration. Model dangerous combinations of individually permitted actions before any external system executes them.

Model
Bounded BFS

Deterministic symbolic reachability

Execution
Local

Runs in your browser; no credentials collected

Decision
Allow / Block

Action-by-action policy simulation

Predictive laboratory

All scenarios use synthetic data. The predictor explores abstract states, not live exploits. A local result does not authorize real tool execution.

Forecast & traces

Ready for analysis

Choose a scenario and run the predictive engine.

Security engine self-test

Execute the four synthetic regression scenarios in this browser. Each test checks the actual engine decision, not a prewritten result.

Distributed research surfaces

Independent instruments remain independent. Links navigate to native sources; private app integrations require their own authenticated backend adapters.

Research browser

The site opens approved destinations in a separate tab. External pages generally disallow iframe embedding through browser security headers. This viewer does not bypass those protections.

Edge deployment is authenticated; no secret credentials are placed in public pages.

Authenticated Edge Compute

Run the same class of symbolic exploration through the independent Supabase FlowShield edge service. Authentication is supplied per request and never saved in this site. This capability requires an authenticated Supabase user session JWT; it does not grant access to Notion, Linear, Drive, or private accounts.
