Codex's engine ships as a native console-subsystem binary (codex.exe). Launched
from our console-less Electron process tree, Windows allocated a fresh *visible*
console window for it; closing that window wedged the run in a pending state.
(Claude Code is a Node CLI, so it never triggers this.)
The window is created by @openai/codex's launcher (bin/codex.js), which spawns
codex.exe with no windowsHide. Patch it via pnpm to pass windowsHide: true
(CREATE_NO_WINDOW) so the console stays hidden — no window, nothing to close.
Replace workspace-scoped builtin file tools with general-purpose file-* tools that accept relative, absolute, and ~/ paths. Relative paths still resolve against the configured workdir.
File operations within the workdir are auto-approved. File operations outside the workdir now emit file permission metadata and require user approval, with support for once, session, and persistent grants.
Add a shared filesystem layer for text-focused read/write/edit/list/search operations, including binary-file safeguards for text reads. parseFile and LLMParse continue to read file buffers for document/image parsing.
Update copilot prompts, background/live-note agents, knowledge workflows, and renderer labels/UI to use the new file-* tool surface and permission details.
Add package-local Vitest setup for @x/core with colocated filesystem unit tests covering path resolution, canonical permission paths, binary detection, read/write/edit behavior, glob, and grep.
