+- The product is named **Tunaxis**.
+- The distribution is `tunaxis-codegen`, the import is `tunaxis_codegen`, the
+  CLI is `tunaxis-cpp-allowlist`, and the npm package is `@tunaxis/codegen-pyodide`.

Household, joint and retirement accounts and ordinary margin count as their own; a company's or fund's account does not, even a company they wholly own. An account that a proprietary-trading firm or funded-trader program provides or allocates to them, including a challenge, evaluation or simulated account, does not count as their own either.
 - **Investment management** — managing, advising on or trading investment capital, or researching strategies for it (a friend's, clients' or investors' capital, an endowment, a pension fund, a public fund, a foundation's treasury, or an account a proprietary-trading firm or funded-trader program provides or allocates, including challenge, evaluation and simulated accounts), is **Commercial Use for every individual and every organization**, noncommercial organizations included, except Personal Trading.

-The PineForge Source License 1.1 replaced 1.0, and 1.2 replaces 1.1, for the code on `main` and in releases from 1.3.0 on. Version 1.1 clarified one point, that distributing the software or its output, changed or not, embedded in or bundled with a product or service made available to others is Commercial Use, not free distribution, unless it is for a permitted purpose. Version 1.2 makes two points explicit: an account a proprietary-trading firm or funded-trader program provides or allocates, including a challenge, evaluation or simulated account, is not a person's own account or capital, so trading it is not Personal Trading; and the capital in such an account, real or simulated, is investment capital, so trading it is investment management, which is Commercial Use. It changes nothing else. Release 1.2.0 was published under 1.1 and keeps that text; 1.3.0 is the first release published under 1.2.

 ## What this repository is
 
-A pure-Python PineScript v6 → C++ transpiler that emits source against the public PineForge engine C-ABI. It implements PineScript v6 from **TradingView's publicly published language documentation**; it does **not** incorporate TradingView proprietary source. Names like "PineScript v6" are used **nominatively** to describe the input language.

Names like "PineScript v6" are used **nominatively** to describe the input language.
 
 ## Third-party components
 
 The transpiler has **no runtime dependencies** (`transpile()` and `transpile_full()` are its supported Python entry points). Development/test extras declared in `pyproject.toml` (`pytest`, etc.) are under their own upstream licenses. The opt-in compile checks invoke a C++ compiler against the separately-licensed Apache-2.0 engine headers; they skip cleanly without an engine checkout.

References to "PineScript v6" and any compatibility/parity statements are **nominative** and factual — compatibility and technical testing only, not a partnership or certification.
