+# CLAUDE.md — asr-api-python
+
+> Repo-specific guidance for AI coding agents. Inherits global conventions
+> (no Claude attribution in commits; never commit generated `*_pb2.py`,
+> `*_pb2_grpc.py`).
+
+## What this is
+
+Public Python distribution of Techmo ASR's gRPC stubs. Distributed on PyPI
+as `techmo-asr-api`. Wraps proto files (vendored in `proto/`) into a
+ready-to-import package with version-aliased modules (`asr_api.v1`,
+`asr_api.v1p1`, `asr_api.dictation`).
+
+## Stack and entry points
+
+- Python ≥3.8.
+- gRPC stubs generated from `proto/` at install time via `setup.py`.
+- `asr_api/__init__.py` — package init.
+- `asr_api/v1.py`, `v1p1.py`, `dictation.py` — version alias modules
+  (re-export the generated `techmo.asr.api.<version>` namespace).
+- `asr_api/VERSION.py` — single-source version (consumed by `pyproject.toml`).
+- `setup.py` — runs `grpc_tools.protoc` on the proto list at build time
+  (`build_package_protos` for `--python_out`, `build_package_grpc_protos`
+  for `--grpc_python_out`).
+
+## Setup vs install
+
+This repo does **not** follow the techmo `setup.sh` / `install.sh` split —
+it has no scripts at all. Per `README.md`, install with stock pip:
+
+```bash
+python3 -m venv .venv
+source .venv/bin/activate
+pip install --require-virtualenv --upgrade pip
+pip install --require-virtualenv .
+```
+
+If you need to use `uv` for parity with internal repos, the equivalent is:
+
+```bash
+uv venv .venv && source .venv/bin/activate
+uv pip install -e .
+```
+
+The `pip install` step triggers `setup.py`, which calls `grpc_tools.protoc`
+to generate the `*_pb2.py` / `*_pb2_grpc.py` files into the `google/` and
+`techmo/` package trees.
+
+## Generated files — never commit
+
+The `.gitignore` explicitly excludes `google/` and `techmo/` precisely
+because they are populated at install time. If `git status` shows changes
+under those paths, do NOT stage them — re-run `pip install` and rely on
+the local venv. The global protoc-output rule applies in full.
+
+The proto sources themselves (`proto/google/rpc/status.proto`,
+`proto/techmo/api/status.proto`, `proto/techmo/asr/api/.../asr.proto`) ARE
+git-tracked — those are the inputs.
+
+## Dependency pins (load-bearing)
+
+- `grpcio-tools>=1.49.4,<1.63` — caps protobuf 5; raising the upper bound
+  breaks the protobuf-4 compatibility this package ships under.
+- `grpcio>=1.49.4,<1.63`
+- `protobuf>=4.21.3,<5`
+
+Don't relax without coordinating with downstream services that pin against
+this package.
+
+## Build / test / lint / run
+
+This repo defines no test, lint, or run commands of its own.
+
+- Build/install: `pip install .` (triggers proto compile).
+- Smoke test: after install, `python -c "from asr_api import v1p1 as api; assert hasattr(api, 'StreamingRecognizeRequest')"`.
+- No `Makefile`, no `pytest`, no `.github/workflows`, no `.gitlab-ci.yml`.
+
+## Repo-specific gotchas
+
+- **`submodules/asr-api/` directory is not a git submodule** in this repo.
+  There is no `.gitmodules`. The proto files are vendored directly under
+  `proto/`. If `submodules/asr-api/` exists in your working tree, it's a
+  local artefact (likely from a sibling internal repo's setup) and is safe
+  to ignore.
+- Versioned modules (`v1`, `v1p1`, `dictation`) are kept as separate aliases.
+  Adding a `v1p2` means: drop a new `proto/techmo/asr/api/v1p2/asr.proto`,
+  add it to the two `protos_paths` lists in `setup.py`, and create an
+  `asr_api/v1p2.py` alias mirroring `v1p1.py`.
+
+## Related repos
+
+- `github.com/techmo-pl/asr-api` — proto definitions (this repo vendors a
+  copy under `proto/`).
+- `github.com/techmo-pl/asr-client-python` — higher-level ASR client built
+  on top of this package.
+- `gitlab.devtechmo.pl/asr-team/asr-api-python` — internal mirror.
+
+## Sections intentionally omitted
+
+- **`setup.sh` / `install.sh`** — repo doesn't have them; uses stock pip.
+- **CI** — none.
+- **Tests / lint** — none defined.
