The codegen consumes a schema from any backend and emits typed client code for any frontend — it doesn't belong inside a backend adapter. That placement was historical sediment from when there was only a Django backend; it predates the AFI generalization. New top-level slot: `protocol/` for protocol-level tooling. Tree is now: backends/ server protocol adapters frontends/ client kernel + per-framework adapters cores/ shared language-level primitives protocol/ protocol-level tooling workers/ runtime workers / bridges Codegen moves to `protocol/mizan-generate/`. Same file layout under `generator/` (cli.mjs, lib/), preserved via git mv. Package metadata cleaned up: - name: "generate" (placeholder) → "mizan-generate" - description filled in - type: module (cli.mjs is .mjs ESM, was previously declared "commonjs") - bin entry added so `npx mizan-generate --config <config.mjs>` works once the package is published, instead of `node path/to/cli.mjs`. Path-reference fixups: - backends/mizan-django/README.md: `node path/to/...` → `npx mizan-generate` - backends/mizan-fastapi/README.md: same - ISSUES.md: file paths in three issue entries - CLAUDE.md: codegen description + Package Layout section refreshed (added protocol/, mizan-fastapi entry, mizan-python entry) - docs/AFI_ARCHITECTURE.md: Package Layout refreshed identically Verified codegen runs from new location: regenerated the FastAPI example harness's api/ output, identical to pre-move.
