Proving Parity on Regulated Financial Reporting Before Cutover

A bank migrating its risk and finance reporting cannot cut over until an internal audit function accepts that migrated figures are identical to the source.

How the work runs

The pressure that made this worth automating, the steps the system runs, and what came out the other side.

Pressure & Trigger Points

  • Any variance between source and migrated output, however small, blocks sign-off entirely.
  • Rounding, null handling, and date-boundary behaviour differ subtly between the source and target platforms.
  • Audit needs documented evidence per report, not a summary assurance that migration succeeded.

Deterministic Replay

Source and migrated reports are executed against the same frozen dataset so any difference is attributable to the migration, not to data movement.

Input Signal:

Real-time operational telemetry & queue

Reasoning Pattern:

MCP grounded vector inference

Governance Gate:

Policy constrained with audit write-back

Verified Business Outcomes

  • Parity evidenced per report rather than asserted across the programme.
  • Audit sign-off obtained on documented comparison rather than on assurance.
  • Cutover gated on evidence, so no report moved before it was proven.

Capabilities this relies on

  • system connectors
  • document intelligence
  • parity validation
  • workflow orchestration
  • nl to query
