+## Project authorization for background repository work
+
+Background provisioning and workspace maintenance have no responsible task user.
+They must not retain a task's identity. A signed-in project workspace writer can
+select their own active, company-installed GitHub Connector grant in project
+settings and explicitly authorize the project. The binding stores the exact grant
+ID and consenting user, never a credential. Revocation records a project lifecycle
+event so subscribed providers can reconcile the change.
+
+`GET /api/projects/:id/git-authorization` returns the current binding and only the
+viewer's eligible personal grants. `PUT` accepts `{ grantId }` or `{ grantId: null }`.
+Agents cannot create this standing consent. Project workspace writers can remove it.
+Core rechecks membership, Connector installation/enablement, grant status, and
+repository metadata on each background use. Public repositories never require
+a connection or credential. Private repositories wait for authorization before
+provisioning starts, so missing consent cannot leave a failed anonymous clone.
+Repository selections retain the same visibility metadata used by the UI lock.
+Legacy workspaces use existing Connector catalog metadata, with anonymous
+GitHub discovery only when visibility is unknown. Unknown visibility defers
+provisioning; it is never assumed public. It never substitutes another grant
+when the selected one fails. Replacing a grant requires explicit reauthorization.
+Project consent follows the selected connection's current GitHub repository access,
+including repositories added to the project later. It does not create a second
+repository approval list. Project repository editors may add sources within that
+connection's access; manage permitted repositories in the GitHub connection.
+Background export also rechecks the consenting user's project read access and the
+project's existing trust policy. Low-trust or unverified projects cannot export a
+raw credential through standing consent.
+Cloud owner access is rechecked through current Cloud authority and the managed
+owner-elevation setting on every private background export; saved local admin
+roles cannot replace that authority. An unavailable authority check cannot confer
+owner access, though explicit project membership still applies.
+
+The trusted plugin capability `projects.git-credentials` enables
+`ctx.projects.resolveGitCredential(projectId, workspaceId, companyId)`. The host
+binds requests to the active project lifecycle or workspace operation; data, UI,
+tool, and proactive calls do not carry this authority. Repository URLs come from
+stored project workspaces. Foreground preparation uses the live run's accepted
+identity and standard trust checks, even when background project consent exists.
+Maintenance ignores originating run/agent context and uses project consent only.
+After archival, existing consent remains usable only for host-issued workspace
+inspection and removal. New provisioning and new consent remain blocked.
+
+The provider receives a transient GitHub token with its existing provider
+permissions. This is not a repository-scoped or read-only token minting API.
+Only grant-listed repositories can trigger background export. Plugins must never
+save tokens in entities, state, configuration, operation receipts, or logs, and
+must send them only to trusted execution infrastructure over HTTPS. Revocation
+prevents subsequent credential acquisition; it cannot recall a token already
+sent to an in-flight operation. Existing tasks and Git credential fallback rules
+outside this plugin API are unchanged.

+## Project Git authorization
+
+Project workspace writers can use `PUT /api/projects/{id}/git-authorization` to
+consent to their own eligible personal GitHub Connector grant. This route is
+board-only; agent requests cannot establish standing consent. `GET` requires
+project read access and returns no token. SDK `projects.resolveGitCredential`
+requires `projects.git-credentials` and a matching host-issued project operation.
+Background work uses the selected project grant. Foreground preparation uses the
+active run identity and trust boundary. UI/data/tool invocations have no export
+authority. No task identity is retained for maintenance.
+Background export rechecks the consenting user's project read access and project
+trust policy. Repository access follows the selected connection, including later
+project additions; no separate project repository approval list is stored.
+Archived projects allow only host-issued workspace inspection and removal using
+existing consent; they cannot acquire credentials for provisioning.
+
+Evidence: owned embedded-database grant/route fixtures in
+`server/src/__tests__/project-git-authorization.test.ts`, worker invocation
+fixtures in `server/src/__tests__/plugin-worker-manager.test.ts`, and capability
+and scope denials in `packages/plugins/sdk/tests/host-client-factory.test.ts`.
+These are automated fixture checks, not live provider qualification.

+### Project Git credentials
+
+Trusted workspace providers can declare `projects.git-credentials` and call
+`ctx.projects.resolveGitCredential(projectId, workspaceId, companyId)` from the
+matching host-issued project lifecycle or workspace operation. Other invocations
+cannot obtain credentials through this method. The workspace must be a current
+repository in that project and company; plugins cannot supply arbitrary URLs.
+
+Background work uses a project writer's explicit consent to their own personal,
+company-installed GitHub Connector grant. It does not retain task context. Core
+checks the exact grant and its owner's active company membership on every use.
+Foreground preparation uses the active run's identity and trust policy instead.
+Public repositories return null and require no connection. Private repositories
+without authorization wait before provisioning. Repository visibility comes from
+the Connector catalog and retained project selections; legacy URL-only sources
+use anonymous discovery when visibility is unknown. A revoked or invalid private
+repository authorization fails closed. There is no fallback to another grant.
+Project consent follows the connection's current repository access, including
+sources added later, rather than a separate project repository approval list.
+The consenting user must retain project read access, and background credential
+export requires the project's existing trust policy to allow standard execution.
+Archived projects keep credential access only for host-issued workspace inspection
+and removal with existing consent; provisioning remains blocked.
+
+The return value is transient raw credential material with the Connector's
+existing permissions. This capability is for trusted execution infrastructure,
+not agent-facing tools or UI. Never expose or persist it. See
+[GitHub identity](../../../doc/execution-github-identity.md#project-authorization-for-background-repository-work).
