The commands read the world (discovery + list-tabs), compute a plan, then apply it -- never mutating while walking, which is how `up` stays idempotent. sl0ppij.ts process wrapper; every piece of state comes back out of list-tabs/list-panes, so there is nothing to desync layout.ts composes the tab node around a project's fragment root.ts root resolution, session naming, the root registry workspace.ts up / ls / open / close index.ts dispatch + the fail-open wrapper Four things this turned up that reading the code would not have: - `attach --create-background` fails with "There is no active session!" when the caller is itself inside a session -- which sl0ppi almost always is, being run from the user's daily-driver terminal. Session creation now runs with the SL0PPIJ*/ZELLIJ* markers stripped: we are creating a new detached session, not nesting. - falling open by passing our own argv to sl0ppij just produces "unrecognized subcommand: up" and still leaves the user without a terminal. Our verbs and flags are stripped first, so what is handed over is something sl0ppij actually understands. - attaching panics in the client when stdin is not a tty, so `up` from a script or CI step died. It now reports the session is ready and exits. - a start_suspended pane reports `is_held`, not `exited`. Conflating them made `ls` claim every agent was running when none had started. Plugin panes (the status bar, the link handler) also inflated pane counts and are now excluded as chrome. Index conventions were verified against a live session rather than inferred, because guessing closes the wrong tab: list-tabs `position` and `close-tab --tab-id` are 0-based, `go-to-tab` is 1-based, and closing renumbers every tab after it, so batched closes run in descending position order. Verified end to end against a real session (three projects, one shipping a custom fragment): up creates the session with all tabs and their purposes; up again reports "up to date" with tabs unchanged; ls reports panes and agent:suspended correctly; open creates-and-focuses and resolves unique prefixes; close removes a tab; deleting a project auto-closes its tab; and with the root itself missing, nothing is closed at all. 64 tests green.
