Projects created before folder-linked Projects can't link a local folder — Context offers only Upload / Add text / GitHub, no migration path

Environment

• Claude desktop app, macOS (Darwin 25.6), Projects view — observed 2026-09-09
• Project "HeartOfGold", created earlier in 2026 (originally under another name), used daily; ~10 chats, Instructions set
• Newer Projects in the same account show a linked local folder; this one does not and offers no way to add one

Steps to reproduce

1. Open a Project created before folder-linked Projects existed.
2. Sidebar → Context → +.
3. Observe the menu: Upload from device, Add text content, GitHub. Nothing to link a local folder.
4. Open the Project's ⋮ menu: no folder option there either.
5. Create a brand-new Project: the folder option is offered.

Expected

Either the same Project can be linked to a local folder after creation, or there is a first-class "migrate / duplicate with folder" action that carries Instructions, Context and Project memory across.

Actual

The old Project is stuck in upload-only mode. The only "live source" offered is GitHub sync, which is not a substitute for repositories deliberately kept off GitHub (this one holds a home-network device inventory and is mirrored on a NAS instead).

Impact

• Every refresh of Project context is a manual drag-and-drop of snapshots that go stale the same day; the Instructions have to warn the model that uploads may be out of date.
• CLI / Claude Code workflows can't feed the Project at all: nothing a tool writes lands in the Project, whereas a linked folder is exactly the surface they write to.
• Long-lived Projects are the ones most worth keeping (accumulated chats and memory) and the ones penalised: the only way to get the folder is to recreate the Project and lose continuity.
• Assistant sessions working from the repo naturally assume "the Project has a folder" because newer ones do — we had to write a standing rule into the repo README to stop that.

Ask

1. Allow linking a local folder to an existing Project (same UI as at creation).
2. Failing that, a documented migration: new Project with folder, with Instructions, Context items, memory and chats moved over in one action rather than by hand.
3. Meanwhile, state in the Context "+" menu that folder linking is unavailable for this Project, so users don't hunt for it.
