AhaSignals Financial AI Point-in-Time Integrity Benchmark — v1.1.0

What changed

Version 1.1 preserves the five frozen v1.0 compatibility cases and adds three BigBear.ai cases covering the complete knowledge-state transition: previously reported, withdrawn from reliance, and restated.

• 8 accession-aware PIT cases
• 2 evaluation tracks: evidence-restricted retrieval and knowledge-contamination control
• 16 machine-readable prompts and reference responses
• required abstention during the BigBear.ai non-reliance interval
• deterministic scorer with a temporal-integrity hard-failure rule
• byte-identity checks for every frozen v1.0 artifact

The bundled reference fixture passes 16/16 responses. The deliberate future-value leak in the adversarial fixture is rejected. These results validate the fixtures and scorer; they are not a result for any third-party model or investment strategy.

AhaSignals Point-in-Time Backtest Validation Benchmark — v1.0.0

Version 1.0.0 freezes five source-dated reference cases for detecting common point-in-time failures in SEC-filing backtests.

Included cases

• AS-PIT-001 — blocks a later comparative value from overwriting the first-reported CoreWeave value.
• AS-PIT-002 — prevents a later sign change from leaking into an earlier information set.
• AS-PIT-003 — preserves Super Micro preliminary evidence as ineligible for the completed-filing matrix.
• AS-PIT-004 — records an evidence and comparability upgrade even when the derived value is unchanged.
• AS-PIT-005 — rejects a synchronized-quarter rank when NVIDIA and AMD fiscal period ends differ.

Reference result

• 5 of 5 cases passed
• 28 CoreWeave source vintages across 14 matched fact identities
• Benchmark payload SHA-256: b22aa620b67838f3fb21cdaf4a947c69d93b7e7ad71e5b653e18855625a5e5a4
