universe-studio

Studio mode for a tagged workspace — the one-tag, four-approvals orchestrator (#474). Given an idea and an active workspace (ralphy workspace use <ws>), it runs production end-to-end as FOUR stages, each auto-assembled and auto-repaired against that workspace's own eval rubric before you see it: (1) location/cast → phase style-lock; (2) scenario → phase scenario; (3) scene anchors → phase assets; (4) final montage → phase eval. Each stage: assemble → ralphy workspace eval <id> → read the per-criterion scorecard → the #473 bounded repair loop (FREE editor fixes auto-loop; PAID regeneration STOPS for your approval) → present ONLY when the stage's criteria clear → wait for your stage approval before advancing. You make four decisions; everything else repairs itself against the universe's hard bar. GENERIC: parameterized by the ACTIVE workspace — works for ANY workspace with an evaluators.json + stageGates. It SEQUENCES the per-role playbooks (scenarist / art-director / editor) under the eval gates; it does NOT replace them. USE WHEN the user says "studio mode", "run my universe end-to-end", "make a <universe> video with the gates", "I'll make four approvals", "auto-assemble and auto-repair against my evals", "drive the staged studio for <workspace>", or tags a workspace and drops an idea expecting the staged-gate flow.
