-# V1 API Migration Checklist
-
-The app is currently hybrid. In this document, V1 refers to the legacy unprefixed server APIs used by `@opencode-ai/sdk/v2`, despite the SDK package name.
-
-## Events
-
-- [x] Replace `GET /global/event` with `GET /api/event`.
-  - `src/context/server-sdk.tsx`
-- [x] Reduce current granular session and message events into the existing app projections.
-  - `src/context/server-session-v2-reducer.ts`
-  - `src/context/server-session.ts`
-- [ ] Remove transitional session event dependencies: `session.created`, `session.updated`, `session.diff`, `session.status`, `session.idle`, and `session.error`.
-  - `src/context/global-sync/event-reducer.ts`
-  - `src/context/server-session.ts`
-  - `src/context/notification.tsx`
-  - `src/pages/session/usage-exceeded-dialogs.tsx`
-- [ ] Remove legacy message event compatibility: `message.updated`, `message.removed`, `message.part.updated`, `message.part.removed`, and `message.part.delta`.
-  - `src/context/global-sync/event-reducer.ts`
-  - `src/context/server-session.ts`
-- [x] Adapt current permission and question events to the existing request model.
-  - `src/context/global-sync/event-reducer.ts`
-  - `src/context/permission.tsx`
-- [x] Consume current file watcher events.
-  - `src/context/file.tsx`
-- [x] Consume current VCS events.
-  - `src/context/global-sync/event-reducer.ts`
-  - `src/pages/session.tsx`
-- [x] Consume current `pty.exited` events.
-  - `src/context/terminal.tsx`
-- [ ] Migrate LSP and reference events.
-  - `src/context/global-sync/event-reducer.ts`
-
-## Sessions
-
-- [x] Replace `GET /session/status` with one server-scoped `GET /api/session/active` snapshot plus V2 execution events.
-  - `src/context/server-sync.tsx`
-- [x] Migrate session listing from `GET /session`.
-  - `src/context/server-sync.tsx`
-  - `src/context/directory-sync.ts`
-  - `src/pages/layout.tsx`
-- [x] Migrate the remaining direct session read from `GET /session/:sessionID`.
-  - `src/components/titlebar.tsx`
-- [x] Migrate session updates from `PATCH /session/:sessionID`.
-  - `src/context/directory-sync.ts`
-  - `src/context/layout.tsx`
-  - `src/pages/home.tsx`
-  - `src/pages/layout.tsx`
-  - `src/pages/session/timeline/message-timeline.tsx`
-  - `src/components/titlebar-tab-nav.tsx`
-  - Renames use `POST /api/session/:sessionID/rename`; archival uses `POST /api/session/:sessionID/archive`.
-- [x] Migrate session deletion from `DELETE /session/:sessionID`.
-  - `src/pages/session/timeline/message-timeline.tsx`
-- [x] Remove session diff loading from `GET /session/:sessionID/diff`.
-  - Historical Session diffs remain unavailable until the current API defines their snapshot semantics.
-- [x] Migrate abort from `POST /session/:sessionID/abort`.
-  - `src/components/prompt-input/submit.ts`
-  - `src/pages/session/use-session-commands.tsx`
-  - `src/pages/session.tsx`
-- [x] Migrate revert and unrevert from `POST /session/:sessionID/revert` and `POST /session/:sessionID/unrevert`.
-  - `src/pages/session/use-session-commands.tsx`
-  - `src/pages/session.tsx`
-- [x] Replace `POST /session/:sessionID/summarize` with the current compact API.
-  - `src/pages/session/use-session-commands.tsx`
-- [x] Migrate slash commands from `POST /session/:sessionID/command`.
-  - `src/components/prompt-input/submit.ts`
-- [x] Migrate shell execution from `POST /session/:sessionID/shell`.
-  - `src/components/prompt-input/submit.ts`
-- [x] Migrate session fork from `POST /session/:sessionID/fork`.
-  - `src/components/dialog-fork.tsx`
-- [ ] Migrate sharing from `POST /session/:sessionID/share` and `DELETE /session/:sessionID/share`.
-  - `src/pages/session/use-session-commands.tsx`
-  - `src/pages/session/timeline/message-timeline.tsx`
-  - Blocked: the current API has no sharing contract or implementation.
-
-## Session Compatibility Fallbacks
-
-These calls are retained as fallback adapters. The current production path supplies the current session and message APIs.
-
-- [ ] Remove fallback `GET /session/:sessionID` after compatibility support is unnecessary.
-  - `src/context/server-session.ts`
-- [ ] Remove fallback `GET /session/:sessionID/message` after compatibility support is unnecessary.
-  - `src/context/server-session.ts`
-- [ ] Remove fallback `GET /session/:sessionID/message/:messageID` after compatibility support is unnecessary.

-- [ ] Migrate experimental worktree listing, creation, removal, and reset from `/experimental/worktree`.
-  - `src/pages/layout.tsx`
-  - `src/components/prompt-input/submit.ts`

-- [x] Migrate built-in provider OAuth authorization and callbacks to `/api/integration/:integrationID/connect/oauth/*`.
-  - `src/components/dialog-connect-provider.tsx`
-- [ ] Migrate remaining credentials from `PUT /auth/:providerID` and `DELETE /auth/:providerID`.
