# Wacc Weight Sum Check

Check that the capital weights in a WACC build sum to one.

## Scope
Preparation and review only. No account action or professional decision.

## Inputs
The equity and debt weights and the computed WACC.

## Workflow
1. Record the equity and debt weights.
2. Sum the weights.
3. Flag any gap from 100%.
4. Return the check without model changes.

## Output contract
equity_weight | debt_weight | weight_sum | gap_from_100 | wacc_reliable

## Fictional acceptance test
Fictional WACC build uses an equity weight of 65% and a debt weight of 30%: the weights sum to 95%, not 100%, a 5-point gap that makes the quoted 7.8% result unreliable.

## Review gates
Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
