+# 0011: Dynamic panels have persistent local identities
+
+Status: accepted for the GPUI product slice.
+
+The six-surface fixture remains a deterministic benchmark shared with Floem; it
+is not the product's panel database. GPUI layers an unbounded workspace registry
+above it. Add Panel creates Terminal, Browser, Markdown, or Review beside the
+selected panel. Each new panel receives a monotonically increasing `PanelId`
+that is never derived from its title, position, surface, process ID, or visible
+index.
+
+The registry persists panel identity, kind, title, target, order, attachment,
+selection, and the next unused ID as one versioned, credential-free SQLite
+snapshot. Invalid snapshots fail closed to the seed layout rather than partially
+restoring aliases. SQLite never stores terminal output, credentials, private
+keys, subscription tokens, or Buzz identity secrets through this boundary.
+
+Every Terminal panel uses its `PanelId` as the runtime-registry key. Detaching
+changes only layout attachment, so the actor and PTY keep running. Reattaching
+selects the same ID. A restored in-process spike must currently launch a new PTY
+for that persisted panel because actor durability across UI process restarts
+requires the planned separate Lumbridge runtime and authenticated IPC; the UI
+does not pretend otherwise.
