Raw internal changelogs are archived in changelog/.

v.2026.04.01

Added — Effort Level (Think) Selector in Automation Studio

• Effort chip row in launch panel — New Off / Low / Med / High / Max selector visible when Claude Code CLI is selected. Frosty glass chip design with tier-based accent colors (warm gold for Max, cool blue for Med). Selection persists via storage
• Profile-aware visibility — Effort section auto-hides when switching to Codex or Gemini profiles, re-appears on Claude Code. Applied in both main launch panel and quick timer
• --effort flag plumbed through all launch paths — Flows through loop launch, agent launch, quick timer, and scheduled loops. Stored in loop state JSON for traceability

Fixed — MCP Registration Path Wrong on Windows Global Install

• Onboarding wizard generated broken paths — getMcpSetup() used DATA_HOME for the MCP entry file path. On Windows global npm installs, DATA_HOME resolves to %APPDATA%/synabun while run.mjs lives in PACKAGE_ROOT (%APPDATA%/npm/node_modules/synabun). The generated ~/.claude.json pointed to a non-existent file, silently breaking MCP startup
• All tool configs now include full env block — Claude CLI, Cursor, Windsurf, and .mcp.json configs now include DOTENV_PATH, SYNABUN_DATA_HOME, and MEMORY_DATA_DIR
• Startup warning for misconfigured global installs — Server logs a warning when SYNABUN_DATA_HOME is unset and PACKAGE_ROOT contains node_modules

Fixed — Edit Plan Shows Wrong Content

• Stale fallback chain picked up post-plan messages — extractPlanText() was called lazily when the user clicked "Edit plan", by which time remember results and stop hook outputs had been rendered in the DOM. The backward DOM walk picked these up instead of the actual plan
• Eager plan capture — Plan content is now captured immediately when ExitPlanMode is detected, before any post-plan messages exist. Removed unreliable disk scan fallback that found stale files from previous sessions
• State cleanup on plan toggle — All 3 plan mode entry points now clear cached plan data when toggled ON, preventing stale data inheritance

Fixed — Browser Rendering Parity with Real Chrome

• Viewport and DPR overrides removed — Set Playwright viewport: null in headed mode so pages render at actual window size. Removed forced deviceScaleFactor: 1 — Chrome now uses native DPR (2x on Retina). Fixes white-page rendering on complex SPAs like Twitter/X

Fixed — Terminal Text Cropped at Bottom

• FitAddon box-sizing mismatch — The global * { box-sizing: border-box } reset caused xterm's FitAddon to overcalculate available rows by ~2 (40px padding mismatch). Fix: box-sizing: content-box on terminal viewport elements — no visual size change

Fixed — Codex CLI Config Parse Error

• TOML serialization wrote JSON syntax — tomlUpsertSection() serialized the env field as {"key":"value"} (JSON) instead of {key = "value"} (TOML inline table). Codex CLI rejected with "missing assignment between key-value pairs". Added proper tomlSerializeValue() helper

Fixed — Greeting Re-fires on Every Message

• Greeting directive persisted in session context — The SessionStart hook injected the greeting into additionalContext which persists for the entire session. Claude saw "begin with this greeting" on every turn. Moved greeting injection to the prompt-submit hook (message 1 only) so it never persists

Fixed — Windows Cross-Platform Hook Compatibility

• Hooks embedded machine-specific absolute paths — When installed into SynaBun's own settings, hook commands contained macOS-style paths that failed on Windows PowerShell. Fix: generate relative paths when target matches PACKAGE_ROOT. Cleanup now matches both relative and absolute-path variants

Fixed — Pre-WebSearch Hook Hangs on PowerShell

• Missing stdin timeout — On PowerShell, stdin end event may never fire, causing the hook to hang indefinitely. Added 2000ms timeout fallback

Fixed — Hooks Crash with Unhandled Errors

• All 7 hooks now handle uncaught exceptions — Added process.on('uncaughtException') and process.on('unhandledRejection') to every hook. Each outputs valid JSON appropriate to its hook type and exits cleanly to prevent "hook error" messages

Changed — Browser Stream Defaults to OFF

• Screencast streaming disabled by default — Stream only runs when explicitly toggled ON in Settings. All 7 check sites updated across server and UI modules

Changed — Loop Browser: Shared System Chrome with Tabs

• One-time Chrome restart per NI boot — ensureChromeDebuggable() ensures Chrome runs with --remote-debugging-port=9222. Graceful AppleScript quit with polling, then killall fallback. Result cached — subsequent calls just probe the port
• Shared session architecture — Replaced per-loop Chrome restarts and 15-second UI polls with shared CDP sessions. Opens new tab per loop instead of creating isolated sessions. Loop stop closes only the loop's tab, preserving the shared session
• MCP session fallback — When SYNABUN_BROWSER_SESSION is pinned but stale, auto-selects or creates instead of failing

Changed — Dependency Updates

• mcp-server — 44 packages updated: @modelcontextprotocol/sdk 1.27.1→1.29.0, @inquirer/prompts 8.3.0→8.3.2, vitest 4.1.0→4.1.2, @types/node 22.19.13→22.19.15
• neural-interface — 17 packages updated: @anthropic-ai/claude-code 2.1.71→2.1.89, playwright 1.58.2→1.59.0, ws 8.19.0→8.20.0. Fixed lodash prototype pollution vulnerability
