A swarm-ci-metrics host unit on a 5-minute timer lists every forge repo's Actions runs as the new read-only ci-metrics account and pushes each finished run's duration and queue wait over OTLP, stamped at the run's stop time. The first pass backfills from run 1. swarm-controller mints the account's token into bao and keeps a ci-metrics team with read on the Actions unit in every organisation. Closes #5376

//! The swarm's secret-store client: where a credential lives, and how both ends
|
|
//! reach it.
|
|
//!
|
|
//! The HTTP is [`vaultrs`]'s job. What this crate owns is the *agreements* —
|
|
//! the rules every path obeys ([`path`]), the translation from this
|
|
//! deployment's environment into a logged-in client ([`client`]), and, per kind
|
|
//! of secret, the path it lives at together with the fields it holds
|
|
//! ([`matrix`], [`queue`], [`mtls`], [`forge`], [`github`], [`grafana`],
|
|
//! [`acp`], [`ci`], [`review_classifier`], [`builder`], [`ci_metrics`],
|
|
//! [`claude_login`]).
|
|
//! Each of those is a thing the controller and a hive must say identically, so
|
|
//! it is said once here.
|
|
//!
|
|
//! [`policy`] is the same kind of agreement seen from the other side: which of
|
|
//! those paths a given principal's own token may read — a hive's, and an
|
|
//! agent's, which are two documents because they are two shapes of grant rather
|
|
//! than one with a name in it. It belongs here rather than in the controller
|
|
//! because the grant and the path are one statement — spelled differently they
|
|
//! produce a 403 that names neither.
|
|
//!
|
|
//! [`client`] is deliberately ignorant of all of it: it moves whatever type a
|
|
//! caller names, so a second kind of secret is a new module beside [`matrix`]
|
|
//! and not another field on a struct shared with it.
|
|
//!
|
|
//! [`mtls`] is the one module about reaching the store rather than about a
|
|
//! value inside it, and its doc explains why that is not circular.
