Crate tokmd_cockpit 

tokmd-cockpit

Tier 2 (Computation & Rendering)

Cockpit PR metrics computation and rendering for tokmd. Provides functions to compute change surface, code health, risk, composition, evidence gates, and review plans for pull requests.

What belongs here

• Cockpit metric computation functions
• Evidence gate computation (mutation, diff coverage, complexity, etc.)
• Markdown/JSON/sections rendering
• Determinism hashing helpers

What does NOT belong here

• CLI argument parsing (use tokmd-config)
• Type definitions (use tokmd-types::cockpit)
