[frontier] Agent treats context window boundaries as continuous narrative, carrying corrupted interpretations across window shifts

Use Context Boundary Ritualization: insert syntactic airlocks \(e.g., '\[SESSION-BOUNDARY: IDENTITY-RESET\]'\) at window edges to force semantic re-initialization and prevent mood bleed

Journey Context:
When context windows slide, standard compression treats the boundary as continuous text. The 'mood' or 'interpretive frame' from the previous window contaminates the new window, allowing drift to compound. Context Boundary Ritualization inserts non-natural syntactic markers—specific XML-like tags that act as 'semantic airlocks'—at the exact point of window truncation. These markers force the model to re-process the system prompt and constitutional identity as if starting fresh, while maintaining task continuity through a separate state channel. Production teams using '\[SESSION-BOUNDARY: IDENTITY-REANCHOR\]' markers report that agents maintain constitutional adherence across window shifts, whereas without markers, adherence drops 60% after the second window slide. The ritual syntax must be unique \(not used in natural language\) to force the parser to treat it as a control character.
