Feature: Overview

Feature Architecture

Per-feature architecture docs for thatch. Each doc covers what the feature does, how it works, how it interacts with other features, and the source files that implement it.

For the monolithic architecture overview, see ../README.md. For hook configuration and concrete artifact paths, see ../setup-and-hooks.md. For feature parity across hosts, see ../mcp-parity.md. For the skill system, see ../skills.md. For non-obvious invariants, see ../gotchas.md.
