+pane ids are workspace-scoped and stable across workspace reorder:

+- `w64e95948145ed1-2`
+- `w64e95948146a82-1`
 
 that means:
 
-- first number = current workspace number
-- second number = current pane number within that workspace
+- workspace id = stable workspace identity
+- pane number = compact pane number within that workspace
 
-these are compact public ids for the current live session. they are **not durable database ids**. if a workspace or pane closes, higher numbers compact down.
+workspace ids are durable for the life of the workspace and survive display reordering. pane numbers are still compact public numbers, so if a pane closes, higher pane numbers in that same workspace compact down.
 
 tabs are first-class socket api objects now.
 
-- tab ids look like `1:1`, `1:2`, `2:1`
-- first number = workspace number
-- second number = tab number within that workspace
-- pane ids still stay workspace-scoped like `1-2` rather than becoming `workspace-tab-pane` triples
+- tab ids look like `w64e95948145ed1:1`, `w64e95948145ed1:2`
+- workspace id = stable workspace identity
+- tab number = tab number within that workspace
+- pane ids still stay workspace-scoped like `w64e95948145ed1-2` rather than becoming `workspace-tab-pane` triples
+
+for backward compatibility, requests also accept the older positional forms like `1`, `1:2`, and `1-2` as shorthand for the current session order. responses use the stable ids.
