# Runtime Behavior Decisions

**Last updated:** 2026-09-24

The documentation migration identified these existing behaviors for separate
product consideration. Implementation status and any selected direction are noted
below; this document does not claim that runtime changes have landed.

- Decide whether the `never` retention selection should delete successful-run
  diagnostics; current behavior is documented in
  [operations](../operations.md#retention-behavior).
- Resolved: [configuration](../config.md) now treats explicit zero as disabling
  transient retries or structural repair independently; PromptKit performs both.
- Decide whether missing or null input timestamps should be rejected; current
  decoding is documented in the [input contract](../integrations/transcript-glossary-files.md).

These decisions are independent of the completed documentation migration and
release workflow.
