Three-zone review workspace: controls, chart canvas, and evidence inspector.
Public evidence report
Prototype evidence report
A concise route-by-route report for Chart Review Lab. Each public page keeps the same boundary: chart review, visualization, annotation evidence, visible data-source caveats, and no advisory workflow.
Server-side endpoints expose chart data and status without browser-side credentials.
Drawing-library integration stays out of the main demo path until approved access is available.
No symbol selection advice, rankings, alerts, broker actions, orders, account state, or execution behavior.
What each page proves
Public route proof points
/prototype
Open prototype
Annotation evidence workspace
Demonstrates Alpaca-backed candles, deterministic labels, inspectable values, annotation JSON, and chart/source artifact actions in the selected Evidence Bench layout.
/widget-demo
Open widget demo
TradingView widget view
Shows the public widget as a clean chart surface and states its limitation: chart display is available, but programmable native drawing APIs and JSON export require Advanced Charts.
/api/datafeed/status
Open status JSON
Datafeed health endpoint
Public JSON endpoint for checking the server-side datafeed status, feed selection, provider caveats, symbol metadata, and latest returned bar context.
Inspectable artifacts
Evidence links and source caveats
Artifact links
Source caveats
- Market data is provided through Alpaca-backed server endpoints.
- TradingView attribution remains visible on widget and planned Advanced Charts surfaces.
- Advanced Charts integration remains gated; private library files are not included.
- Prototype annotations are deterministic visual review artifacts, not advice or automation.
QA checklist
Responsive review criteria
Desktop
Controls, chart canvas, evidence inspector, artifact actions, and caveats fit in a single bench layout.
Mobile
Status, controls, chart, annotation evidence, JSON, artifacts, and caveats stack in a clear sequence.
Language
Copy uses chart review, visualization, annotation, artifacts, datafeed, caveat, and readiness terms.
No hover-only proof
Annotation labels, selected evidence, source metadata, and public artifact links are visible on the page.
