Replace the synchronous /edit (wait for full markdown response) with an
async + SSE flow per demo.html so the user sees text stream in real-time
and can interact with permission/question events the agent raises.
Backend
-------
- EditHandler now calls OpenCode /session/:id/prompt_async and returns
immediately with {ok, sessionId, notebookPath}; the LLM reply is no
longer embedded in this response.
- New GlobalEventHandler proxies OpenCode /global/event as
text/event-stream. Server forwards ALL events; the client filters.
A too-eager server-side ?session= filter was silently dropping events
the client would have accepted, so it was removed.
- New PermissionReplyHandler + QuestionReplyHandler forward user
replies (once/always/reject and freeform answer) back to OpenCode
Serve at /session/:sid/permissions/:permId and
/session/:sid/question/:qId/reply.
- OpenCodeClient gains send_message_async(), stream_global_events()
(async generator over the SSE feed via tornado streaming_callback),
reply_permission() and reply_question(). Legacy send_message_sync
removed.
Frontend
--------
- subscribeOpenCodeEvents() opens a fetch+reader SSE client (XSRF
token injected from serverSettings); AbortController-backed close()
is idempotent.
- OpenCodeInlinePrompt.applyEvent() routes events into the streaming
UI: text delta -> assistant message (re-rendered as markdown on
every delta so the user sees formatted <pre><code> blocks in
real-time, not raw fence source); reasoning/tool/permission/question
get collapsible details blocks. session.idle resets stream pointers
and fires onStreamEnd.
- Permission/question blocks render real interactive UI: three
buttons (once/always/reject) for permission, a text input + submit
for question. Click handlers post through the new API routes and
show success/failure status in place.
- Centralized idle detection (4 shapes: top-level + payload-nested
x {session.idle, session.status/idle}) inside the prompt; cell
action reacts via onStreamEnd callback rather than re-parsing
event types.
- System / workspace / pty / lsp / mcp / installation events AND
session-level control events (agent.switched, model.switched,
file.edited) are not rendered in the frontend.
Tests

The inline prompt now shows the current session's full message
history (user + assistant), scrollable, replacing the single-output
display from the previous commit. The user can scroll back through
prior exchanges in the same notebook's OpenCode session.
Server (opencode_bridge/):
- New route: GET /opencode-bridge/session-messages?notebook=<path>
- Resolves notebook to session via SessionManager.peek (no create).
- If no session: {"messages": []} (no OpenCode call).
- Else: GET /session/{id}/message on OpenCode Serve, project the
raw {info, parts}[] into a frontend-friendly {role, content}[].
- OpenCodeClient.list_session_messages(sid).
- SessionManager.peek(notebook_path) -> Optional[str] (read without
creating, to avoid spawning a session just to report emptiness).
- Wired the new route in setup_route_handlers.
Client (src/):
- types.ts: OpenCodeMessage { role, content } + OpenCodeMessagesResponse.
- api/opencode_client.ts: callOpenCodeSessionMessages(notebook, serverSettings).
- components/opencode_inline_prompt.ts:
- Replaces the single .opencode-inline-output area with a
scrollable .opencode-inline-history (max-height 320px, overflow-y
auto, auto-scrolls to bottom on update).
- setMessages(messages): renders user messages as plain text,
assistant messages via marked.parse. No more setOutput/hideOutput.
- components/opencode_cell_actions.ts:
- _showPrompt now fires a _refreshHistory(notebookPath) which
fetches and calls prompt.setMessages.
- _handleResponse on success also calls _refreshHistory (the new
assistant message appears as the last item in the history).
- Cell source is still NOT replaced.
- api/opencode_client module is mocked in the cell_actions test to
avoid jsdom network calls.
style/base.css:
- .opencode-inline-output* rules replaced with .opencode-inline-history
(max-height 320px, overflow-y auto, border, padding) and
.opencode-msg / .opencode-msg-user / .opencode-msg-assistant.
- pre/code/p/h1-3 content styling scoped under .opencode-inline-history.
Tests:
- pytest 37/37: FakeOpenCodeClient.list_session_messages + 3 new
session_messages route tests (no session, projects messages, 400).
- jest 29/29: setMessages renders user/assistant + history area tests.
- FakeSessionManager.peek (returns None when session_id is falsy).

Flow (v3-final corrected):
1. Model call succeeds.
2. Server passes the AI reply through unchanged as 'markdown' (the
system prompt allows ```language fences + a brief explanation, so
the response is real markdown that marked can render into code
blocks, headings, etc.).
3. Client OpenCodeCellActions._handleResponse calls prompt.setOutput(
resp.markdown); the inline prompt widget renders it with
marked.parse and shows it in a new output area (hidden until a
response arrives). The cell source is NOT replaced.
4. User can close the output or cancel the whole prompt.
Server:
- New unified system prompt: '你是代码助手 ... 按指令修改代码,可附简
短说明' (allows ```fences``` + explanation; no more 'no markdown
fences' restriction).
- EditHandler returns {ok, markdown, sessionId, notebookPath} (raw
text, fences intact). _strip_code_fence kept as a helper for any
future apply-to-cell path; no longer called.
- finalSource field dropped (the cell-apply path is gone).
Client:
- OpenCodeSuccess: markdown: string (finalSource removed).
- OpenCodeInlinePrompt: new output area, setOutput(md) renders via
marked.parse, hideOutput() closes it.
- OpenCodeCellActions._handleResponse: setOutput(markdown) instead of
sharedModel.setSource + auto-hide. The prompt stays open so the
user can read the output.
- Uses marked@17 (already in node_modules via JupyterLab; no new dep).
- CSS: output area styling (border, max-height 320px scroll, code/pre
styling, close button).
Tests: pytest 34/34, jest 29/29. marked is mocked in jest.

Per the OpenCode server docs (GET /config/providers), each Provider's
'models' is { [modelID: string]: Model } (a Record), so model IDs can be
referenced as strings (matching the 'default' map of providerID ->
modelID). Our code treated it as Model[], which:
1. crashed with 'p.models is not iterable' on real responses, and
2. after the previous Array.isArray guard, skipped EVERY provider
(a Record is never an array), so the inline picker showed nothing.
Update types.ts (OpenCodeProvider.models -> Record, add OpenCodeModel,
add optional 'default' map to the response) and rewrite
flattenProviders to iterate Object.keys(p.models). Update test fixture
to the Record shape.

A JupyterLab extension that bridges the cell UI to a local OpenCode Serve
process. The extension is a dual package: a Python server extension
exposed under /opencode-bridge/*, plus a TypeScript frontend that
registers per-cell toolbars.
Backend (Python, tornado)
- Slice 1: config + auth + OpenCode HTTP client (tornado.httpclient,
no aiohttp). 4 settings in schema/plugin.json (url, user, password,
request timeout).
- Slice 2: handlers for /hello, /health, /providers, /edit.
- Slice 2.1 (correction): SessionManager with 1 notebook = 1 session
mapping, async-safe via per-path locks, 404 recovery via invalidate().
Two new endpoints: GET /sessions, DELETE /session?notebook=<path>.
- 32 pytest tests pass.
Frontend (TypeScript, JupyterLab 4.6)
- src/types.ts: CellContext, OpenCodeRequest/Response, OpenCodeSettings.
- src/context/cell_context.ts: extract CellContext from a CodeCell +
its parent NotebookPanel, structured error collection.
- src/api/opencode_client.ts: callOpenCodeEdit, callOpenCodeProviders.
- src/components/opencode_cell_footer.ts: OpenCodeCellFooter Widget
implementing ICellFooter with 3 buttons (optimize / fix / edit),
resolved via this.parent instanceof CodeCell. NOT cellToolbar
(does not exist in JL 4.6) and NOT Widget.findParent (removed in
@lumino/widgets 2.x).
- src/components/opencode_cell_factory.ts: Cell.ContentFactory
subclass returning the OpenCodeCellFooter.
- src/components/opencode_installer.ts: installOpenCodeEverywhere
patches every notebook (existing + new) to use the custom factory.
- src/index.ts: registers the factory, loads settings, fetches
/providers on activation and logs the list to the console.
- 23 jest tests pass (mocked JupyterLab boundary, pnpm path safe).
Settings
- 6 fields: 3 auth (url/user/password) + 1 timeout + 2 model selection
(provider/model). Provider list is fetched at startup from
/opencode-bridge/providers and printed to the browser console so
users can copy values into Settings Editor.
Docs
- design.md: 6 sections covering architecture, UI flow, API contract,
TS skeletons, session management (v0.2.1 correction), and
provider/model selection (v0.2.2 addition).
- CLAUDE.md: agent guidance for working in this repo.
- TODO.md: remaining work for Slices 4-7 + v0.4+ backlog.
CI
- Gitea release workflow at .github/workflows/build.yml.
- Bark notification helper (non-fatal on failure).
