fur_cli/commands/
id.rs

1//! Who this machine writes as: `fur id`.
2//!
3//! Attribution, not authentication. There is no password, no verification, and
4//! no server-side identity — a person states who they are and the archive
5//! records it honestly. Institutional identity is a deployment concern.
6//!
7//! Resolution order, first hit wins:
8//!   1. `.fur/identity`                 — this project, this checkout
9//!   2. `$XDG_CONFIG_HOME/fur/identity` — this user, every project
10//!   3. `avatars.json` → `main`         — the pre-existing behaviour
11//!
12//! Rule 3 is why nothing breaks: a machine that never runs `fur id` resolves
13//! exactly as it did before this command existed.
