PRs must flow smoothly through review to reach production. Large PRs should be split into smaller, manageable ones.

## Submitting PRs

1. **Title and Summary**:
   - Use a scannable title: `[Subsystem] Action Description #Issue` (e.g., `[IAM] Add role-based access control #567`).
   - Include context in the summary: what changed, why, and any issue references.

#### Operation

"Операція" (operation) тут означає один з "методів" HTTP.

Один з:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...та більш екзотичних:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

У HTTP-протоколі можна спілкуватися з кожним шляхом, використовуючи один (або кілька) з цих "методів".
