Summary

• Replace Game Hub parent-row Open actions with Edit while keeping game rows as the parent rows.
• Add a theme-backed active-game row state and remove the standalone Open Game Journey action.
• Remove the Game Setup accordion and keep Add game submission on the existing API/service contract.
• Preserve Source Idea and Readiness Output as child row tables under each game parent row.

Validation

• PASS: npx playwright test tests/playwright/tools/GameHubMockRepository.spec.mjs -g "Game Hub creates, opens, and deletes mock games|Game Hub validates game parent rows and child tables|Game Hub preserves guest browsing and blocks guest saves|Game Hub shows a creator-safe empty state when no projects exist|Game Hub shows a creator-safe unavailable state when project list API fails|Game Hub displays and edits game purpose and member role|Game Hub readiness child rows update from mock game state"
• PASS: npx playwright test tests/playwright/tools/IdeaBoardTableNotes.spec.mjs -g "Idea Board uses accordion table ideas and notes"

Notes

• Draft stacked on pr/26174-ALFA-014-game-hub-parent-columns-center.
• Non-gating observation: an exploratory full-file run of GameHubMockRepository.spec.mjs had one unrelated toolbox-role completion-metrics 500 failure; the scoped Game Hub validation lane passed.
