+# GitHub Integration Contract
+
+Lithe connects a GitHub identity directly; it does not require or create a
+Lithe account. macOS currently implements the platform adapters. A future
+Windows implementation consumes the same Rust Core JSON commands.
+
+## Ownership
+
+- Rust Core parses GitHub remotes, validates operation inputs, builds trusted
+ request plans, normalizes responses, orders lists, and translates errors.
+- Platform adapters execute HTTPS, open the verification page, and store the
+ OAuth token in the operating system credential store.
+- The service coordinates authorization and pull-request workflows.
+- The application feature model owns UI state. Views never receive an OAuth
+ token or call GitHub directly.
+
+Rust Core never performs GitHub network I/O. A request plan selects only `api`
+(`https://api.github.com`) or `web` (`https://github.com`); platform adapters
+must not accept an arbitrary host from application input.
+
+## Authorization
+
+The preferred flow is GitHub OAuth Device Flow:
+
+1. `deviceCode` creates a device authorization request using the configured
+ public OAuth client ID and the `repo read:user` scope needed by the supported
+ pull-request mutations.
+2. The UI displays `userCode` and opens `verificationURI`.
+3. `deviceToken` is polled at the returned `interval`. `slowDown` increases the
+ interval by five seconds; `pending`, `expired`, and `denied` are explicit.
+4. The platform stores an authorized token in Keychain or Credential Manager.
+5. `currentUser` validates the token before connected state is published.
+
+An OAuth client secret, personal access token, and GitHub password are never
+requested from the user. Tokens are never placed in Rust requests, logs,
+fixtures, user defaults, or error details.
+
+The macOS product reads `LitheGitHubOAuthClientID` from `Resources/Info.plist`.
+The checked-in public client ID identifies Lithe's product-owned GitHub OAuth
+App for every installation. It is not a credential or secret. Development runs
+may override it with `LITHE_GITHUB_CLIENT_ID`; an empty configuration leaves
+GitHub sign-in unavailable rather than asking the user for a personal token.
+
+## Rust Commands
+
+- `github.parseRemote` accepts `{ "remoteUrl": string }` and supports canonical
+ GitHub HTTPS and SSH remotes. It returns `{ "owner", "name" }`.
+- `github.requestPlan` accepts an `operation` and typed operation fields. It
+ returns `host`, uppercase `method`, absolute `path`, ordered `query`, optional
+ JSON `body`, and `requiresAuthentication`.
+- `github.normalizeResponse` accepts `operation`, HTTP `status`, and raw UTF-8
+ JSON `body`. It returns a normalized value or the standard Core error.
+
+Supported operations are `deviceCode`, `deviceToken`, `currentUser`,
+`listBranches`, `compareBranches`, `listPullRequests`, `getPullRequest`, `createPullRequest`, `updatePullRequest`,
+`listPullRequestFiles`, `listPullRequestComments`,
+`createPullRequestComment`, `createPullRequestReview`, `mergePullRequest`, and
+`updatePullRequestMetadata`.
+
+PR lists are sorted by descending number. Labels, assignees, comments, and
+files are deterministically ordered as demonstrated by
+`shared/fixtures/github/pull-request-v1.json`.
+Branch lists are sorted by branch name and duplicate names are removed before
+they cross the Rust boundary. The first page is capped at 100 branches, which
+matches the current creation workflow's bounded picker.
+Branch comparisons preserve GitHub's commit order and sort changed files by
+repository-relative path. Branch names are percent-encoded by Rust Core before
+they enter the trusted compare request path.
+
+## Product Scope
+
+The first macOS surface supports connect/disconnect, repository resolution
+from `origin`, PR list/detail/create/update, files, conversation comments,
+comment creation, review submission, merge/squash/rebase, close/reopen,
+labels/assignees, and argument-based checkout of the PR head branch.
+Pull-request creation can send the normalized comparison's textual patches and
+commit messages to the user's configured AI provider to draft an editable title
+and Markdown description. Sensitive-file filtering and the configured diff
+character limit are shared with commit-message generation. AI output never
+creates or submits a pull request without the user's explicit action.
+When the opened workspace has a detached HEAD or commits not present on its
+upstream, creation is blocked until the user explicitly publishes the branch.
+Rust Core suggests a branch name and likely base branch, validates the name,
+and performs the branch creation/push mutation; the platform UI reports that
+uncommitted working-tree changes are retained locally and are not part of the
+pull request. A failed push retains the new local branch for a safe retry.
+Line-level review threads, merge queues, and auto-merge are outside this
+contract version.
