System health

Read freshness and evidence quality
without confusing them.

Status shows whether the latest published rows are current enough for operational use, and whether confidence is strong enough for the published label to be read normally. No price data. No forecasts. No recommendations.

Health = freshness relative to expected cadence. Confidence = evidence quality for the published label.
Reading map

Two dimensions.

Health

Freshness relative to the chain-specific publication policy. BTC and ETH are expected roughly daily. ARB and BASE are expected roughly weekly.

Confidence

Evidence quality for the published label. A row can be current and still degraded, or delayed and still internally coherent.

Publication policy

Chain cadence.

Bitcoin · Ethereum
Daily publication policy. A one-day lag is normal.
Expected ~1 day · soft warning above 2 days · hard fail above 4 days
Arbitrum · Base
Weekly-style publication policy by design. Seeing 7d lag is normal.
Expected ~7 days · soft warning above 10 days · hard fail above 15 days

Health classification is derived at render time. Confidence is read directly from the latest published meta artifact.

Status page

How to read the status page

Freshness and confidence are separate operational questions.
×
Basic

This page answers one question: are the published data files current and usable right now?It does not say anything about what markets are doing or what a subscriber should do.

Each chain shows two separate things that are easy to confuse.

  • Health is freshness relative to expected cadence. Bitcoin and Ethereum should update roughly daily. Arbitrum and Base update roughly weekly by design.
  • Confidence is evidence quality for the published label. A row can be fresh and still degraded if the evidence surface is weak.
Advanced

Health is derived at render time from lag versus the chain-specific publication policy. Confidence is read from the latest published meta artifact and measures the evidentiary strength behind the label.

These dimensions are orthogonal. A chain can be delayed but internally coherent, or fresh but epistemically weak. Both are shown to keep operational freshness from masking evidence quality and vice versa.

Traceability
  • Source: latest published meta artifact per chain
  • Lag field: confidence.lag_days_vs_utc_today
  • Confidence field: confidence.confidence_score
  • Health is derived at render time, not read from a stored status field
Status page

Publication cadence

Lag has to be interpreted relative to chain-specific cadence, not relative to zero.
×
Basic

Different chains publish at different speeds by design. That means lag must always be interpreted relative to policy.

  • Bitcoin and Ethereum are expected roughly daily.
  • Arbitrum and Base are intentionally published with an expected 7-day delay.

The operational pipeline generally checks for new upstream data twice daily around 09:00 and 21:00 Europe/Oslo.

Advanced

BTC and ETH use a daily cadence policy: expected 1 day, soft warning above 2 days, hard fail above 4 days. ARB and BASE use a weekly cadence policy: expected 7 days, soft warning above 10 days, hard fail above 15 days.

This is why the same absolute lag value can be normal for one chain and anomalous for another.

Traceability
  • Expected windows: around 09:00 and 21:00 Europe/Oslo
  • BTC / ETH: expected 1d · warn > 2d · fail > 4d
  • ARB / BASE: expected 7d · warn > 10d · fail > 15d
Status page

Confidence on this page

Confidence is evidence quality for the published label, independent of freshness.
×
Basic

Confidence measures how strongly the available data supports the published label.

  • Good (≥ 0.70) means strong evidence.
  • Caution (0.40–0.69) means moderate evidence.
  • Degraded (< 0.40) means weak evidence.
Advanced

Confidence is shown here as an operational diagnostic, not as a market signal. It indicates how well the evidence surface distinguishes the published label from adjacent labels.

A degraded score means the row may still be published for traceability, but the label should be treated as low-trust.
