Desktop 1.18.30: opening a moved Git project reuses its missing canonical path and stale session directories

Description

OpenCode Desktop 1.18.30 redirects a moved Git project back to its old, nonexistent directory, even when I explicitly select the new directory in “Open project.”

Related: #47803 and #46330. I saw that #46330 was closed via #46713 for the OpenCode 2 launch. This report confirms the behavior on the 1.18.30 desktop release; I have not tested the OpenCode 2 beta. The PR description also explicitly leaves existing session history unchanged.

Steps to reproduce

1. Open a Git project at /Users/example/dev/old/repo in Desktop and create a session.
2. Move the project, including .git, to /Users/example/dev/new/repo. The old directory no longer exists.
3. In Desktop, choose Open project and explicitly select the new directory.
4. Desktop resolves the project back to the old location instead of consistently opening the selected directory.

Expected: Open the selected directory. If existing sessions still reference a missing location, provide a supported way to reassociate them while preserving history.

Actual: The old canonical path is retained and reused. The backend can initialize the new directory, but logs also contain FileSystem.realPath / ENOENT failures for previously registered locations.

Diagnostic evidence

Paths and project identifiers below are anonymized. Inspection before the local repair showed:

Record	Stored value
project.id	Same project ID before/after the move, also cached in .git/opencode
project.worktree	/Users/example/dev/old/repo (missing)
project.sandboxes	["/Users/example/dev/new/repo"]
project_directory.directory	/Users/example/dev/new/repo
session.directory	8 existing sessions still bound to the old directory

Desktop's opencode.global.dat also retained old locations in server, layout and layout.page, including encoded session-route keys.

In Project.fromDirectory at v1.18.30, an existing non-global project's canonical path is retained:

worktree: projectID === ProjectV2.ID.global ? worktree : existing.worktree,

The newly resolved directory is then added to sandboxes; the existence filtering below applies to sandboxes, not the retained worktree. This matches the database state above.

Local recovery required backing up the database/UI state and correcting the project path, affected session directories and desktop navigation references. Database integrity and preservation of all 8 session records were verified; final UI verification after restarting was still pending when preparing this report. A supported relocation/recovery flow would avoid manual SQLite and desktop-state edits.

Plugins

oh-my-openagent@latest is configured. The log also contains a separate plugin-loading error involving the bun: protocol. I have not reproduced this in plugin-free mode; the project-path persistence behavior above was verified independently in the database and shipped source.

OpenCode version

Desktop 1.18.30 (Electron). Separately installed CLI: 1.17.9; the reported workflow uses Desktop.

Operating System

macOS 26.5.2, build 25F84, Apple Silicon (arm64).
