Validate poll selection counts before sending polls

[cubrift]

Problem

The poll schema in messages/ai/schemas/AIMessagePollSchema.js accepts any numeric selectableCount, including zero, negative values, fractions, and values larger than the number of options. Invalid values can be rejected by WhatsApp/Baileys or create polls that do not behave as intended.

Expected behavior

A generated poll should always have a positive integer selection count that does not exceed the number of available options.

Suggested direction

Add numeric constraints to the schema and, if needed, a cross-field validation step that compares selectableCount with values.length.

Acceptance criteria

• selectableCount must be an integer of at least 1.
• It cannot exceed the number of poll options.
• Invalid values are rejected before sock.sendMessage is called.
• Valid single-select and multi-select polls continue to work.

This is incorrect, the schema specifically only allows a minimum of 2 and maximum of 12.
