vela-scientist 0.153.0

//! # vela-scientist — the agent layer
//!
//! Sits on top of `vela-protocol`. Reads a researcher's working
//! directory and emits `StateProposal`s tagged with an `AgentRun`
//! for reviewer-facing provenance. Never signs canonical state.
//!
//! v0.22 ships **Literature Scout** only: PDF folder → `finding.add`
//! proposals. Other agents (Notes Compiler, Code Analyst,
//! Contradiction Finder, Experiment Planner, Reviewer Agent) land
//! one at a time in v0.23+.
