It never calls GitHub, so the App stays installed on the GitHub organization, and it touches no other factory or OuterLayer organization that uses the same installation. Work items on the unlinked repositories keep their history. Answers the repositories it unlinked. If the factory's control plane was one of them, the factory falls back to its first-linked remaining repository, as for an unlink. ## OpenAPI ````yaml /openapi.yaml delete /v1/apps/{appId}/installations/{installationId} openapi: 3.0.3 info: contact: email: hello@outerlayer.ai url: https://www.outerlayer.ai description: >- The OuterLayer Gateway API lets you ingest coding-agent sessions and record evidence of work programmatically. Most teams reach it through the `outerlayer` CLI, which calls it for them. Call it directly to build your own integration or to automate what the dashboard does. Versioning: every endpoint is prefixed with `/v1/`. Breaking changes ship under a new version prefix (`/v2/`, etc.) with a 90-day-minimum deprecation window; anything additive lands on the current prefix. Vocabulary: the dashboard calls this API's `app` a **factory** — the unit that owns a set of repositories, the agent sessions worked on them, and the evidence they produce. They are the same entity. The API keeps `app` in its paths, headers, and field names because those are a published contract; only the product surface was renamed. title: OuterLayer Gateway API version: '1.0' servers: - description: Production (OuterLayer Cloud) url: https://api.outerlayer.ai - description: Local dev server (self-hosted gateway) url: http://localhost:9418 security: - AppId: [] BearerAuth: [] tags: - description: >- What a CLI login token can read about its owner without naming a factory, such as the factories they can use. name: Account - description: >- Coding-agent session ingest (outerlayer sync) and content-addressed session images. name: Agents - description: >- Evidence artifacts (screenshots, recordings, reports, logs) emitted as proof of a change and anchored to pull requests. name: Artifacts - description: >- Pass/fail outcomes of checks run in your own CI or compute, anchored to pull requests with the run URL as proof. name: Emitted Results - description: >- The acceptance criteria of a work item, recorded as one list.
