Additionally, in instructional sentences, prefer the present tense for obligations:

- Prefer `vous devez …` over `vous devrez …`, unless the English source explicitly refers to a future requirement.

- When translating “make sure (that) … is …”, prefer the indicative after `vous assurer que` (e.g. `Vous devez vous assurer qu'il est …`) instead of the subjunctive (e.g. `qu'il soit …`).

### Quotes

## Managing hermetic Python

To make sure that TensorFlow's build is reproducible, behaves uniformly across
supported platforms (Linux, Windows, MacOS) and is properly isolated from
specifics of a local system, we rely on hermetic Python (see
[rules_python](https://github.com/bazelbuild/rules_python)) for all build
and test commands executed via Bazel. This means that your system Python
installation will be ignored during the build and Python interpreter itself

## Why this policy exists

There is a fundamental **asymmetry** between submitting a contribution and reviewing one: AI tools make it easy to generate and submit large amounts of code, but they do not make it equally faster for us to review it. 
This policy protects our limited review budget, allowing us to invest our attention wisely.

	// Add new service requests here.
)

// Global service signal channel.
var globalServiceSignalCh = make(chan serviceSignal)

// GlobalContext context that is canceled when server is requested to shut down.
// cancelGlobalContext can be used to indicate server shutdown.
