Reviewer finding resolved through host confirmation:

• Exact 83-byte manifest is retained at control/primary/regression.json and control/review-1/regression.json.
• Content declares only cypress/e2e/bazaar-chart-range.cy.ts with no config overlays.
• /task/regression.json was hidden by the managed-sandbox read policy, not missing.
• No repository manifest was added or tracked.

The source/spec patch remains unchanged and narrowly covers the reported Bazaar range-handle defect. It does not affect authentication, billing, player data, API boundaries, or deployment configuration.
