Web UI: New Session creates in wrong project, /project/init returns HTML, Settings missing Projects tab, Auto-accept toggle broken

[VictorHuy2711]

Description

Four issues in the Web UI when OpenCode is accessed via browser (not desktop app):

1. "New Session" button creates session in wrong project — clicking New Session from homepage defaults to the first non-global registered project instead of the project the user is working in. Workaround: navigate to specific project's session URL first, then click New Session.

2. POST /project/init returns HTML instead of JSON — API endpoint that should register a new project returns the SPA HTML page, making programmatic project registration impossible.

3. Settings page missing Projects tab — Web UI Settings has no way to add/manage projects. Only desktop TUI can do this.

4. Auto-accept permissions toggle broken — The toggle in Web UI Settings > Agent cannot be enabled; clicking has no effect (desktop TUI works fine).

OpenCode version

Latest from npm (opencode-ai), version 1.16.2

Steps to reproduce

1. Start server: opencode web --port 4096 --hostname 0.0.0.0
2. Open browser at http://127.0.0.1:4096/
3. Click "New Session" on homepage — session created in wrong project
4. Settings page: check for Projects tab (missing), try toggle Auto-accept (broken)
5. API: curl -X POST http://127.0.0.1:4096/project/init -H "Content-Type: application/json" -d "{\"directory\":\"D:\\\path\\\to\\\workspace\"}" — returns HTML

Operating System

Windows 11

Terminal

Windows Terminal (not relevant — these are Web UI bugs)

Plugins
