Module demo 

The no-keys demo: firstpass demo.

A self-contained, real-HTTP demonstration of the whole Firstpass loop. It stands up a local server that speaks the Anthropic wire protocol (the cheap model returns a weak answer, the next rung a good one), runs one enforce-mode decision through the real proxy, and prints the audit receipt — which model was tried, which gate caught what, what it cost, and what it saved versus always calling the top tier. Then it reports a downstream outcome via the feedback API and shows it attach without breaking the tamper-evident chain.

Everything here is real code over real HTTP; only the upstream is local, so no API keys are needed. Point the same proxy at real providers (base URLs + BYOK) and it behaves identically.

This lives in the library, not in examples/, so it ships inside the firstpass binary and is therefore reachable from every install channel — uvx firstpass demo works without a Rust toolchain. examples/demo.rs is a shim over this same code so the cargo invocation in older docs keeps working.

Functions

run

Run the demo end to end. Prints to stdout; leaves no state behind (the trace DB is a temp file).
