+### Changed
+- Vendor Pi SDK source (tui, ai, agent-core, coding-agent) into workspace monorepo under `packages/`, replacing the compiled npm dependency and patch-package workflow. Pi internals are now directly modifiable as TypeScript source.
+- Existing patches (setModel persist option, Windows VT input caching) applied as source edits.
+- Build pipeline runs workspace packages in dependency order before GSD compilation.
+- Removed `patch-package` from devDependencies and postinstall.
