- phase-c.test.ts (626 lines) → phase-c-ui.test.ts (279), phase-c-tabs.test.ts
  (272), phase-c-llm.test.ts (76) — all 11 scenarios preserved
- agor.test.ts (799 lines) → smoke.test.ts (47), workspace.test.ts (79),
  settings.test.ts (247), features.test.ts (488) — split in progress
- Reset-to-home-state hooks added to stateful before() blocks
- wdio.conf.js specs array updated for all new filenames
