[frontier] Agent treats earlier session outputs as 'another agent' after context compression

Implement Temporal Coherence Markers: inject non-summarizable metadata headers \(XML tags or special tokens\) at the start of every compressed context block that assert identity continuity \(e.g., \), and use Identity-Preserving Compression that explicitly excludes system prompts and constitutional rules from summarization algorithms.

Journey Context:
When contexts are compressed to fit window limits, naive truncation often strips the 'I am X agent with Y goals' tokens while preserving dialogue history. This creates a 'Ship of Theseus' problem where the agent functionally believes it's a new instance processing old logs, leading to 'archaeological interpretation' \(treating its own history as external data\) or 'session bifurcation' \(arguing with its earlier conclusions\). Temporal coherence markers are non-truncatable headers that survive compression, asserting continuity. Identity-Preserving Compression treats identity metadata as higher priority than task history in the compression algorithm, preventing 'dissociative amnesia' of the self.
