# Key Event Default Value Policy Cutoff

Explain a value-setting change without restating older key events.

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

## Inputs
Dated default-value settings, event times, supplied timezone, before/after report exports.

## Workflow
1. Record when the default policy changed.
2. Use the owning documentation that default changes apply only to future key events.
3. Separate older missing values from newly default-derived values.
4. Return a comparable-period note without rewriting historical data.

## Output contract
event_time | effective_policy | previous_value | default_applies | report_basis | hold

## Fictional acceptance test
Fictional default 20 begins Oct 12. An Oct 11 event with no value does not retroactively become 20. Missing effective timestamp prevents assigning the new default to a boundary event.

## 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.
