Proof Library
Searchable repository of evidence receipts, audit trails, and decision artifacts. CFO-grade documentation for every value event.

What Is the Proof Library?

The Proof Library is a centralized, searchable repository of all evidence receipts, audit trails, and decision artifacts generated by Kincaid IQ. It ensures that every value claim, every savings calculation, and every operational decision is backed by traceable, timestamped, cryptographically verified evidence.

CFOs, auditors, and compliance teams can query the library to answer questions like:

  • What evidence supports this $500K rebate claim?
  • When was this data last refreshed?
  • Who approved this decision and when?
  • What was the confidence score of this anomaly detection?
  • Can I trace this value back to the source query in Snowflake?

Receipt Structure

{ "id": "rcpt-pbm-q4-2025-variance", "title": "PBM rebate variance analysis Q4 2025", "hash": "sha256:a1b2c3d4e5f6...", "freshness": "PT10M", "confidence": 0.94, "sourceSystem": "snowflake", "sourceRef": "query-abc-123-456", "url": "https://app.snowflake.com/...", "createdAt": "2025-12-15T14:30:00Z", "meta": { "warehouse": "ANALYTICS_WH", "database": "CLAIMS", "schema": "PBM", "tables": ["REBATE_GUARANTEES", "ACTUAL_PAYMENTS"], "rowCount": 12847, "executionTime": "4.2s" } }

id: Unique identifier for this receipt

title: Human-readable description

hash: SHA-256 hash of query results (tamper-proof)

freshness: Age of data (ISO 8601 duration: PT10M = 10 minutes)

confidence: ML model confidence score (0.0 - 1.0)

sourceSystem: Origin system (snowflake, databricks, servicenow, etc.)

sourceRef: Query ID or record ID in source system

url: Direct link to evidence in source system

meta: Additional context (warehouse, tables, execution stats)

Key Features

Cryptographic Hashing
SHA-256 hashes ensure data integrity. Any tampering or drift is immediately detectable.
Freshness Tracking
ISO 8601 durations (PT5M, PT1H, P1D) show data age. Alerts trigger when receipts become stale.
Confidence Scores
ML model confidence (0.0 - 1.0) indicates prediction reliability. Low confidence = manual review required.
Source Lineage
Direct links to Snowflake queries, Databricks notebooks, ServiceNow tickets. Full traceability.
Search & Filter
Query by date range, source system, confidence threshold, freshness, hash, or custom tags.
Audit Export
Export receipts to CSV/JSON for external audits, regulatory compliance, or board reporting.

Use Cases

CFO Audit Preparation
Export all receipts for Q4 2025 with confidence > 0.9 and freshness < 24 hours. Provide to external auditors for verification.
Regulatory Compliance
Prove that all rebate claims are backed by cryptographically verified evidence from Snowflake within 15 minutes of detection.
Dispute Resolution
Vendor disputes $200K rebate claim. Provide receipt with hash, freshness, and direct Snowflake query link as proof.
Board Reporting
Generate executive summary of all REALIZED value events with receipts showing source data lineage and confidence scores.
Data Quality Monitoring
Alert when receipts show confidence < 0.7 or freshness > 1 hour. Trigger DQ investigation workflow.
Deterministic Replay
Replay historical queries using stored query IDs. Validate that results match original receipt hashes (no data drift).

Integration with War Room & Ledger

Every arbitrage event in the War Room includes one or more receipts from the Proof Library. When an event is approved and moved to the Verified Savings Ledger, the receipts travel with it, creating an immutable audit trail from discovery → approval → realization.

1.
Discovery: Snowflake query detects $340K rebate variance
2.
Receipt Generated: Hash, freshness, confidence recorded in Proof Library
3.
War Room: Event surfaces with receipt badge ("🔒 Verified")
4.
Approval: CFO reviews receipt, signs packet, moves to ledger
5.
Ledger Entry: $340K moved to APPROVED state with receipt link
6.
Realization: Rebate collected, ledger updated, receipt preserved

Security & Compliance

The Proof Library is designed for SOC 2 Type II and HIPAA compliance, with:

  • Immutable Storage: Receipts stored in append-only log (no deletion/modification)
  • Encryption at Rest: AES-256 encryption for all stored receipts
  • Access Logs: Every receipt access logged with user, timestamp, IP address
  • Role-Based Access: Granular permissions (viewer, operator, approver, admin)
  • Audit Exports: Tamper-proof exports with cryptographic signatures
  • Data Retention: Configurable retention (7 years default for financial records)
Make value provable.
Kincaid IQ turns complex cost and operational opacity into an auditable ledger with evidence receipts, controls, and action workflows.
