Admin MVP

Edit widget demo-advanced-kline

F038 separates persisted UUID reconciliation from preview-only widget codes. Without an app-owned admin session, persisted reads fail closed and the builder remains preview-safe.

Preview-only edit route

Route id demo-advanced-kline is a public/demo widget code, not a persisted UUID. The builder below uses safe preview state only and does not pretend to have loaded a saved backend widget.

Builder

Preview-safe builder

The builder below never uses manual admin tokens. Save Draft is a preview-save gate until authenticated persisted save is enabled behind feature flag.

not-run

Widget builder MVP: configure, Apply, let backend preview validation run, Save Draft through preview-safe gate, preview desktop/tablet/mobile, then copy embed code. Copy uses the last applied and backend-accepted config only.

Advanced KLine Chart

Saved vs applied policy

Copy can use preview-safe code after backend validation, but published embed remains blocked until persisted save + backend applied/published evidence are verified.

  • Backend preview validation has not accepted the applied config yet.
  • No audited persisted save has been verified in this frontend session.
  • Published/applied backend policy is not verified yet; embed code remains preview-gated.

Persisted mutation feature flag: disabled · persisted attempt: idle. Even when enabled, mutation needs app-owned admin session and audit/read-after-write gates.

Responsive preview

Preview uses the applied draft only. Device widths are contract-driven so mobile/tablet/desktop smoke stays consistent.
