Data-quality diagnostics
The reconciler walks every canonical dataset and reports coverage, verification status, and last-known-good timestamps. Editorial placeholders are explicitly counted as demo so we never accidentally render them as live data. Private user data (portfolio, watchlist, alerts) is never inspected by this view.
Generated 2026-05-23T17:11:58Z. Server-rendered fresh on every request.
Demo data gate
ON — every surface renders editorial placeholders. Charts at /market, /macro, /stocks/[ticker], etc. should be visible.
Driven by env var NKOSUO_ALLOW_DEMO_DATA = (unset). To force OFF, set it to "false".

How to read this
- Verified: an editor reconciled the row against a primary source.
- Source-linked: source URL on file but the row has not been editorially reconciled.
- Derived: computed from a verified input (e.g. ex-date inferred from a dividend announcement).
- Scheduled: cadence-based event (weekly T-Bill auction) where the exact date may shift.
- Unverified: lacks source metadata. We label these clearly so users never mistake them for official data.
- Demo: editorial placeholder. Always rendered with a Demo freshness badge.
What's not here
Private user data — portfolio transactions, watchlists, alerts — is never read by the reconciler. The PortfolioHolding / Transaction / Snapshot rows in the table above are intentionally zero. See the privacy policy for what we collect, store, and never share.
