Invite-only launch: sign in with GitHub, repository access and lifecycle, many emails, a new look1//! Who may do what in a repository: repository roles, the capabilities
2//! each one carries, and how a person's permission is worked out.
3//!
4//! **One table.** [`CAPABILITIES`] says, for each [`Capability`], the
5//! least [`RepoRole`] that has it. Every service asks [`can`] (or
6//! [`permission`]) instead of checking membership itself, the site draws
7//! its Roles table from the same list, and
8//! `packages/contracts/src/access.ts` mirrors it (a test here reads that
9//! file and fails when the two differ).
10//!
11//! **Effective permission** is the highest of:
12//!
13//! - **ownership**: an owner of the repository's workspace has Admin on
14//! every repository in it;
15//! - **the base permission** of the workspace ([`BasePermission`]), which
Merge membership: owners, org roles, GitHub's repo roles, privileges, 2FA16//! every member gets on every repository (Read for a workspace made from
17//! 2026-10-08, [`BasePermission::FOR_NEW_WORKSPACES`]; Write for one made
18//! before, until an owner changes it);
19//! - **a direct grant** ([`RepoGrant`]) to the person, on that repository.
20//! Whoever creates a repository is given Admin on it this way;
21//! - **security manager**: Read on every repository of a workspace where
22//! the person is one, with the security capabilities
23//! ([`SECURITY_MANAGER`]) on top;
Invite-only launch: sign in with GitHub, repository access and lifecycle, many emails, a new look24//! - **public**: anyone, signed in or not, can read a public repository.
25//!
Teams and CODEOWNERS, labels and milestones, dependency updates, the security suite, and a clearer top bar26//! - **a team's grant**: a role given to a team the person is in, or to
27//! one of that team's parents (see [`crate::teams`]). Identity resolves
28//! it into the same [`RepoGrant`]s, with [`RepoGrant::team`] set, so the
29//! rules here treat it as any other grant.
Invite-only launch: sign in with GitHub, repository access and lifecycle, many emails, a new look30//!
31//! Identity attaches a person's grants ([`User::grants`]) and each
32//! membership's base permission ([`Membership::base_permission`]) when it
33//! resolves them from credentials, so asking costs nothing: no call, and
34//! the answer is as fresh as the request.
35//!
36//! **Tokens.** A workspace's own token has Admin on its workspace's
37//! repositories, as it could do everything a member could before roles;
38//! what is for people only stays refused by the checks that say so. An
39//! agent's token carries the memberships and grants of the person it acts
40//! for, cut down to its repository's workspace
41//! (`credentials::intersect`), so it never has more than that person on
42//! that repository, and its scope limits it further.
