Known failures and non-claims

• FilingsBench v0.1 has no human-gold or narrative labels yet.
• Numeric concept selection does not yet cover issuer extension concepts.
• 8-K support is not included in v0.1 because period-duration rules differ.
• Inline-XBRL facts with segment dimensions are intentionally abstained.
• A document can report more than one valid notion of revenue. v0.1 uses a fixed US-GAAP priority and exposes the chosen concept as evidence.
• Confidence is rule support, not a calibrated probability. Calibration metrics remain unreported until a sufficient gold-labeled set exists.
• Registrant names are strict-matched in v0.1. Filing legal names can differ from SEC Submissions aliases (for example CORPORATION vs CORP), so the strict score understates entity identity matching; no fuzzy-match score is claimed.
• The deterministic baseline does not evaluate any Uraion model. No model-quality claim is made.
• The Dockerfile is provided but was not built in the audit environment because no Docker runtime was installed; CI verifies the native Python package only.
