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.

design.md section 3 updated for the new async /edit response shape
and the new GET /events SSE endpoint.

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.

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).
Generated artefacts ignored: opencode_bridge/labextension/, _version.py,
*.tsbuildinfo, junit.xml, test.ipynb scratch notebook.
