Aurora Diary Synthesis

The technical objective is to synthesize a multi-layered narration from nested observational data, following a specific recursive pattern. The process involves wrapping a core observational line within multiple layers of observer insights, ensuring that the final output preserves the chronological and hierarchical structure of the aurora recordings.

The final output must be a single string where each observer layer adds a "begins:" header and a "notes:" footer around the inner content. The solution must handle empty observer lists by returning only the root line and correctly manage multiple nested levels while maintaining strict newline formatting. This ensures archival integrity and provides a standardized format for Lumenfjord’s astronomical diaries.

Examples

Example 1

Input

root_line = "A pale arc crowns the fjord.", observers = [{"name": "Kael", "insight": "Stars echo in the ice."}, {"name": "Lysa", "insight": "Upper bands split in two."}]

Output

Lights ripple over the tide.

Explanation

Example with input: root_line = "A pale arc crowns the fjord.", observ

Example 2

Input

root_line = "Lights ripple over the tide.", observers = []

Output

Eira begins: Lights ripple over the tide. Eira notes: Green curtains meet the reef.

Explanation

Example with input: root_line = "Lights ripple over the tide.", observ

Example 3

Input

root_line = "Lights ripple over the tide.", observers = [{"name": "Eira", "insight": "Green curtains meet the reef."}]

Output

Kael begins: Lysa begins: A pale arc crowns the fjord. Lysa notes: Upper bands split in two. Kael notes: Stars echo in the ice.

Explanation

Example with input: root_line = "Lights ripple over the tide.", observ
