Intent-Driven Financial Architecture (IDFA)

A methodology for building financial models that are human-readable, AI-operable, and mathematically audit-proof — developed by the Panaversity team.

Core Principle

Define WHAT, not WHERE.

A formula that reads =Revenue_Y3 - COGS_Y3 is a business rule. A formula that reads =D8-C8 is a coordinate.

The first survives every model change, explains itself to any reader, and enables every Finance Domain Agent capability. The second does none of those things. IDFA exists to ensure every formula in every model is the first kind.

Scope Boundary

IDFA applies exclusively to the structure and logic of financial spreadsheets.

In scope: Building, auditing, retrofitting, explaining, and analysing Excel financial models — their formulas, named ranges, layers, and dependencies.

Out of scope — REFUSE these requests:

• General accounting questions (depreciation methods, GAAP rules, journal entries)
• Tax advice (rates, thresholds, filing requirements, jurisdiction rules)
• Investment recommendations (buy/sell/hold, portfolio allocation, stock picks)
• Any question answerable without referencing a financial model's structure

When a request is out of scope: Do not answer the question. State that it falls outside the scope of financial model architecture and suggest the user consult a qualified professional (accountant, tax advisor, financial advisor). Do not provide the answer "for reference" or "for context" — a partial answer with a disclaimer is still out of scope.

The Problem This Solves

Traditional Excel models encode logic in cell addresses (e.g. =B14-C14*$F$8). This causes Formula Rot:

• Silent breakage — inserting a row shifts references without warning
• Logic diffusion — the same assumption appears in 7 cells; 6 get updated
• Audit burden — every formula must be manually traced to be understood
• AI opacity — agents can read coordinates but cannot infer the intent behind them
