APXV v1.5.0

Added

• Studio (/studio) — author Agents, Packs, and Proof Profiles; Save → Test → Promote
• Proof Studio — catalog predicates, intent compile, templates, promote to Workbench Proofs shelf
• universal-predicate-v1 Groth16 track — real prove/verify via apxv-zk when keys exist (scripts.setup_universal_zk)
• Workbench polish — freeform board, pan, resizable shelf/inspector, proof profile bind chip, linear order without wires
• Trust hub (/trust) — single entry to Verify, Audit, Governance
• Operator smoke: python -m scripts.smoke_operator_flow (Studio → promote → run + claim + fail-closed)
• UI e2e: e2e/endgame-full.spec.ts (nav, Studio, Workbench run, claim, Trust, Settings)
• Session restore banner on Workbench; Promote gate after successful Test (Force promote on error)
• Health banner: vendor-key degradation with copy-bootstrap + System health deep link
• docs/PROOF-STUDIO.md, docs/MIGRATION-v1.5.md, updated ui/docs/OPERATOR-GUIDE.md

Changed

• Product IA — Studio + Workbench + Runs + Artifacts + Trust + System + Settings (home redirects to Workbench)
• Pack wizard remains advanced at /packs?wizard=1; day-to-day authoring is Studio
• Jobs UI labeled Runs; empty states and CTAs point to Workbench
• Version strings and publish defaults updated to 1.5.0

Fixed

• Wrong “Open Studio” destinations (wizard vs Studio packs)
• Library CTAs that bounced without a pipeline id
• Shell page titles for Artifacts / nested Trust pages
• Workbench Run blocked by sticky status banner overlap
• Canvas freeform edges and kind-colored paths
