1//! Self-hosted runners: a workspace's or a repository's own machines, which
2//! run its workflow jobs (and, when it says so, its agents' work) instead
3//! of g1t's sandboxes. Time on them costs nothing.
4//!
5//! The actions service keeps them, beside the jobs they run. A machine runs
6//! `g1t-runner` (`crates/runner`), which registers once with a short-lived
7//! registration token an admin made, gets a credential of its own, and then
8//! only ever calls out: it polls `api.g1t.sh` for work, runs what it is
9//! given with the same harness g1t's sandboxes use, and reports back. No
10//! port is opened on the machine.
11//!
12//! - A **registration token** (`g1trt_…`) is made by an owner of the
13//! workspace (or an admin of the repository) and lasts an hour. It can
14//! register any number of runners until then, and nothing else.
15//! - A **runner credential** (`g1tr_…`) belongs to one runner. It is stored
16//! only as a hash, rotates every day (the poll that rotates it hands the
17//! new one over), and is revoked when the runner is removed. It can poll
18//! for work, report on what that runner was given, and remove the runner;
19//! nothing else. Any other endpoint refuses it.
20//! - A job is given to a runner when every label in its `runs-on` is one
21//! of the runner's labels (ignoring case), and the runner's group lets
22//! the job's repository use it. A job whose `runs-on` names
23//! `self-hosted` (or a `group`) only ever runs on self-hosted runners; it
24//! waits, saying for which labels, until one picks it up, for a day at
25//! most.
26//!
27//! The management methods take an `actor` and an owner (`repo` or
28//! `workspace`), as secrets do. The runner's own methods take its id and
29//! credential. Mirrors `packages/contracts/src/runners.ts`.
