Creating a worktree wrote the new directory straight into OpenCode's own project storage: the web server updated `storage/project/<id>.json` and ran an `UPDATE project SET sandboxes` against `opencode.db` through better-sqlite3, and the VS Code extension wrote the same JSON. Both wrote behind the back of a running OpenCode process. OpenCode registers a sandbox through `project.addSandbox`, which emits a project-updated event; a direct row write emits nothing, so a worktree created while OpenCode was running stayed unknown to it until a restart. The SQLite write also opened a database file owned by another live process. The VS Code write was inert on top of that: OpenCode v2 reads sandboxes from the database, not from that JSON. Registration is not ours to perform. OpenCode records a worktree as a sandbox itself when an instance boots for that directory, and filters entries whose directory no longer exists when reading them back, so removal needs no counterpart either. The only consumer on our side, the project seed in sync/bootstrap.ts, already falls back to `project.current()` when the seed is absent; the worktree list itself comes from git, not from sandboxes. Reported symptom this targets: a worktree created after `openchamber restart` never answers prompts, and restarting OpenChamber makes it work. Not reproduced locally, so this is not confirmed as the cause.
