Observation record
A complete market observation record for a stale, disputed liquidity signal.
Truth-state rationale
This observation is labeled Stale because it was captured at 09:47Z, twelve minutes past the defined 15-minute freshness window for intraday liquidity signals. By the time the record reached the classification layer, the market microstructure conditions it described may have already shifted.
It is also flagged Disputedbecause the exchange-reported opening auction data conflicts materially with the vendor's estimate. The vendor reports 18% spread widening; the exchange reports 9%. The vendor reports 31% depth decline; the exchange reports 14%. Without resolution, neither figure can be treated as reliable.
The combination of stale + disputed triggers an automatic escalation. The observation cannot enter the reasoning pipeline until an operator resolves the conflict or explicitly overrides the block.
Allowed downstream uses
- —Log the record in the audit ledger with full attribution and conflict flags.
- —Trigger a source-reconciliation workflow to resolve the vendor/exchange discrepancy.
- —Notify the operator that a stale, disputed liquidity signal requires review.
- —Use the record as a case study for calibration of vendor data quality scoring.
- —Include the observation in a post-mortem analysis of auction-period data variance.
Prohibited downstream uses
- —Feed into real-time risk models without explicit operator override and re-validation.
- —Use as a sole justification for any allocation or positioning decision.
- —Blend with live observations without clear labeling of stale and disputed status.
- —Present to any external party as a verified market fact.
- —Trigger automated alerts implying immediate action is required.
Operator review notes
Review timestamp2026-04-13T10:15:00Z
Operator judgmentThe magnitude discrepancy between VendorX and the exchange is too large to ignore. Possible explanations include: (a) different measurement windows within the auction, (b) different depth aggregation methodologies, or (c) a vendor calibration error. I am requesting vendor clarification before this signal is released from escalation.
DecisionDefer / Block
Conditions for releaseVendor must provide auction-subsecond methodology documentation, or a second independent source must confirm the 18% / 31% figures, or the observation must be downgraded to an unverified alternative-data flag with no downstream weighting.
