# Lead Stage Duration Re-Entry Check

Separate completed stage stays from the current open stay before comparing lead-stage durations.

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

## Inputs
Lead/stage IDs, all entry/exit events, latest and cumulative duration exports, cutoff and source definitions.

## Workflow
1. Order supplied stage events while preserving re-entries and missing exits.
2. Calculate completed intervals only; identify the current interval without treating cutoff as an actual exit.
3. Compare latest completed and cumulative completed time under documented field behavior.
4. Explain current-stage values that may still reflect earlier stays; no CRM update or service-level verdict.

## Output contract
lead | stage | completed_intervals | latest_completed | cumulative_completed | open_interval | field_explanation

## Fictional acceptance test
Fictional stage S had completed stays 2 days and 3 days, then a current 1 day open stay. Completed cumulative 5 days and latest 3 days exclude the open stay under the documented behavior. A missing exit remains unknown, not 0.

## 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.
