Research preserving composer line breaks throughout the prompt lifecycle

[alexanderkreidich]

What to build

Research how actual line breaks entered in the composer behave throughout the complete prompt lifecycle: submission, persistence, queue rendering, preview, history, editing, and clipboard copying.

The research should identify every place where line breaks or surrounding blank lines are preserved, normalized, collapsed, or removed. It should then recommend explicit formatting semantics so prompts retain the structure entered by the user without unintentionally changing existing compact queue presentation.

This is a product decision point: document the recommendation and its tradeoffs for review before implementation begins.

Acceptance criteria

• Document the current behavior of composer-entered line breaks through submission, persistence, queue rendering, preview, history, editing, and clipboard copying.
• Identify all intentional and unintentional normalization, including trimming and whitespace collapsing.
• Provide reproducible examples covering internal line breaks, blank lines, and leading or trailing line breaks.
• Recommend exact preservation and display semantics, including whether compact queue rendering should differ from full preview and copied text.
• Define the implementation and regression-test scope that should follow once the recommendation is approved.
