# Win-Loss Evidence Ledger

## Inputs
Approved deal cohort definition, outcomes and dates, authorized buyer interview notes, CRM reasons, deal context and privacy limits.

## Workflow
1. Define which deals and period belong in the cohort. Do not compare dissimilar segments as though they are one controlled sample.
2. Extract buyer statements with source references. Keep CRM reason codes and seller opinions labelled separately. Never invent a buyer quote.
3. Group recurring reasons only when evidence supports them. Preserve counterexamples and distinguish price mentioned from price proven decisive.
4. Return an evidence ledger, cautious patterns and neutral follow-up questions. Do not contact buyers, score salespeople or claim causal certainty.

## Output contract
deal | outcome | buyer evidence | seller hypothesis | source | contradictory evidence | confidence | next research question

## Fictional acceptance test
Fictional three-deal cohort: two CRM losses say price, but only one buyer interview confirms price was decisive. The other buyer mentions missing integration; the third deal has no interview. Report one confirmed price case, one integration case and one unknown, not a two-thirds price-loss claim.

## Review gates
Recount evidence-backed cases, check source ownership and preserve the missing interview. With three records, report observed counts rather than a market-wide conclusion.
