See [Advisor](https://spatney.github.io/rayfin-fabricator/docs/ship/advisor). ## App identity The identity a Rayfin app's connections use when they're set to application access: the owner of the app's Fabric item. For your own apps, that's the Fabric account that first deployed the app; for team apps, the team's deploy identity. Blueprint shows which connections use it. See [Blueprint](https://spatney.github.io/rayfin-fabricator/docs/build/data-model#whose-credentials-the-app-identity-uses). ## App item A Fabric item created by a deployed Rayfin app. Fabricator may also call this a Fabric app or App item when describing deployed apps. See [Deploy to Fabric](https://spatney.github.io/rayfin-fabricator/docs/ship/deploy). ## Autopilot A chat route used after an approved plan when Copilot continues autonomously end to end. See [Chat](https://spatney.github.io/rayfin-fabricator/docs/build/chat). ## Azure CLI Microsoft's command-line tool for Azure. Fabricator uses it for some team workspace setup and administrator flows. See [Team prerequisites](https://spatney.github.io/rayfin-fabricator/docs/team/prerequisites). ## Capacity Fabric capacity is the compute capacity assigned to Fabric workspaces. Team workspace setup asks you to choose a capacity. See [Team prerequisites](https://spatney.github.io/rayfin-fabricator/docs/team/prerequisites). ## Community example A ready-made Rayfin app template from the awesome-rayfin gallery or another template URL. Use **Start from a community example** when creating a project. See [Projects](https://spatney.github.io/rayfin-fabricator/docs/build/projects). ## Deep review A read-only Copilot review started from the Advisor with **Run deep review**. It checks issues that need judgment and cannot edit files or run commands. See [Advisor](https://spatney.github.io/rayfin-fabricator/docs/ship/advisor). ## Deploy identity A Microsoft Entra ID service principal used by a team workspace pipeline to deploy apps to Fabric. Team apps never deploy from a member's computer. See [Team workspaces](https://spatney.github.io/rayfin-fabricator/docs/team). ## Deployment A Rayfin app deployed to a Fabric workspace with `rayfin up`. Fabricator manages deployments from the deployments panel. See [Deploy to Fabric](https://spatney.github.io/rayfin-fabricator/docs/ship/deploy). ## Design mode A preview mode where you select elements in the app, describe visual changes, and send those changes to Copilot. See [Design mode](https://spatney.github.io/rayfin-fabricator/docs/build/design). ## Fabric app A Rayfin app hosted in Microsoft Fabric. In Fabric, the deployed app is represented by Fabric items in a workspace. See [Deploy to Fabric](https://spatney.github.io/rayfin-fabricator/docs/ship/deploy). ## Fabric brokered auth How Rayfin apps sign people in: Fabric signs them in with the Microsoft Entra account they use for Fabric. The app needs no identity provider to run and no app registration of its own in Microsoft Entra ID, so there's nothing for a tenant admin to approve. Rayfin's docs also call it Fabric SSO. See [Blueprint](https://spatney.github.io/rayfin-fabricator/docs/build/data-model#how-people-sign-in) and [Rayfin's auth docs](https://rayfin.ai/docs/auth). ## Fabric workspace A Microsoft Fabric container for app items, data, semantic models, and other Fabric resources. See [Deploy to Fabric](https://spatney.github.io/rayfin-fabricator/docs/ship/deploy). ## Finding An Advisor issue. A finding includes what was flagged, why it matters, where it appears, and how to fix it. See [Advisor](https://spatney.github.io/rayfin-fabricator/docs/ship/advisor). ## GitHub CLI GitHub's `gh` command-line tool. Fabricator uses it for cloning and team workspace repository operations. See [System requirements](https://spatney.github.io/rayfin-fabricator/docs/reference/requirements). ## Microsoft Entra ID Microsoft's identity platform. People sign in to Rayfin apps with their Microsoft Entra account, through [Fabric brokered auth](https://spatney.github.io/rayfin-fabricator/docs/reference/glossary#fabric-brokered-auth). Team workspace deploy identities are service principals in Microsoft Entra ID. See [Team prerequisites](https://spatney.github.io/rayfin-fabricator/docs/team/prerequisites). ## Microsoft Fabric Microsoft's data and analytics platform where Rayfin apps are deployed and hosted. See [Deploy to Fabric](https://spatney.github.io/rayfin-fabricator/docs/ship/deploy). ## Personal preview A team workspace preview deployed for one member's working branch. See [Work on an app](https://spatney.github.io/rayfin-fabricator/docs/team/work-on-an-app). ## Pipeline The GitHub workflow in a team workspace repository that deploys previews and published apps to Fabric. See [Team workspaces](https://spatney.github.io/rayfin-fabricator/docs/team). ## Preview The pane that shows your app inside Fabricator. It can show a local Vite frontend during chat, a deployed app, or the Fabric portal shell. See [Preview your app](https://spatney.github.io/rayfin-fabricator/docs/build/preview). ## Published app The shared version of a team app deployed from the repository's main branch. See [Publish an app](https://spatney.github.io/rayfin-fabricator/docs/team/publish). ## Quick check An Advisor rule that runs locally without Copilot. Quick checks re-run as the project changes. See [Advisor](https://spatney.github.io/rayfin-fabricator/docs/ship/advisor). ## Rayfin Microsoft's platform for building apps that deploy to Microsoft Fabric. Fabricator builds Rayfin apps. See [Rayfin's docs](https://rayfin.ai). ## Rayfin CLI The command-line tool Fabricator runs through `npx rayfin` from each project. It deploys apps and manages Fabric sign-in. See [Rayfin versions](https://spatney.github.io/rayfin-fabricator/docs/ship/rayfin-versions). ## Secret A value such as an API key or password that your app's Rayfin functions read on the server. Secrets are stored with the deployed app and are never shown again. See [Secrets](https://spatney.github.io/rayfin-fabricator/docs/build/secrets). ## Semantic model A Fabric or Power BI model that describes tables, columns, measures, and relationships for analytical data. Fabricator can help connect an app to a semantic model. See [Blueprint](https://spatney.github.io/rayfin-fabricator/docs/build/data-model). ## Skill Reusable instructions or tools that guide the Copilot agent for a specific kind of Rayfin work. See [Skills](https://spatney.github.io/rayfin-fabricator/docs/build/skills). ## Team workspace An experimental shared workspace backed by a private GitHub repository, Fabric workspaces, deploy identities, and a pipeline. See [Team workspaces](https://spatney.github.io/rayfin-fabricator/docs/team). ## Turn One request-and-response cycle in chat. A turn can include tool calls, file edits, diffs, and a work log. See [Chat](https://spatney.github.io/rayfin-fabricator/docs/build/chat). ## Universal App The default template that comes with the Rayfin CLI, used for new projects. It starts small, with no database, and grows into the app you describe in chat. See [Projects](https://spatney.github.io/rayfin-fabricator/docs/build/projects). ## Work log The live list of files read, searches, commands, output, and edits during a chat turn. See [Chat](https://spatney.github.io/rayfin-fabricator/docs/build/chat). ## Working branch The git branch Fabricator creates for your copy of a team app. It is where your changes live before publishing. See [Work on an app](https://spatney.github.io/rayfin-fabricator/docs/team/work-on-an-app). ## Working copy Your local or team-specific copy of an app while you work on changes. In team workspaces, each member works on their own copy before publishing. See [Work on an app](https://spatney.github.io/rayfin-fabricator/docs/team/work-on-an-app).
