Report #89997

[frontier] My agent's context window fills with redundant history, causing it to forget critical instructions.

Implement Semantic Landmark Checkpointing: summarize conversation segments into immutable 'landmark' memories when key decisions occur, then truncate intermediate history while preserving landmarks.

Journey Context:
Simple truncation loses crucial decision rationale. Sliding windows without semantic awareness cause repetition. Landmarks act as compressed episodic memory, allowing aggressive context compression while maintaining causal chains for reasoning.
