web/src/multiview.ts — openDraft's "reuse the empty pane" branch is dead after the first render, and drops the seed when it is not.

The branch is taken only when !target.sessionId && !target.draft. But createSpawnForm sets ready = true and calls emit() at the end of loadProjects(), which assigns leaf.draft = values for every empty pane. A second after load, every empty pane has a non-null draft, so n and the Spawn button always split a new pane instead of reusing the untouched draft already on screen.

Inside the pre-load window the branch is taken — and then the seed is discarded: draftForms.get(leaf.id) returns the already-built form, so leaf.draft = draft() is never read. A quick "Spawn similar" onto a fresh empty pane loses the cloned cwd and command.
