terraphim_agent 1.16.30

//! Learning Capture System for Terraphim AI
//!
//! This module provides automatic capture and indexing of failed commands
//! as learning documents that can be queried via the knowledge graph.
//!
//! # Architecture
//!
//! ```text
//! Failed Command → Secret Redaction → Auto-Suggest → Store as Markdown
//!                                      ↓
//!                              RoleGraph Index
//!                                      ↓
//!                              Query with KG Expansion
//! ```
//!
//! # Usage
//!
//! ```rust,ignore
//! use terraphim_agent::learnings::{capture_failed_command, LearningCaptureConfig};
//!
//! let config = LearningCaptureConfig::default();
//! let path = capture_failed_command("git push -f", "remote: rejected", 1, &config)?;
//! println!("Captured learning: {:?}", path);
//! ```
