Module profiles 

Agent profiles — workload-specific configurations.

Profiles compose existing configuration knobs into named presets. They are loaded from three tiers (highest priority first):

1. Project: .lean-ctx/profiles/<name>.toml
2. User: ~/.config/lean-ctx/profiles/<name>.toml
3. Built-in defaults

A profile can extend another via extends = "parent". Child fields override parent fields; unset fields inherit.
