## Statements (checkable)
0. For commercially distributed apps not approved for the Slack Marketplace, conversations.history and conversations.replies move from Tier 3 to Tier 1: 1 request per minute, and the maximum and default limit parameter is reduced to 15 objects.  [✓0 ✗0]
1. This applies immediately to apps created after May 29, 2025 and to new installations of existing unlisted apps; Marketplace apps and internal customer-built apps are not affected by the reduction.  [✓0 ✗0]

## Fix
```text
Internal (single-workspace) apps are not affected; otherwise get Marketplace approval, cache history, or use the Events API instead of polling history.
```
