Report #62451

[frontier] Agent restored from checkpoint acts as if previous session just happened, ignoring time gaps and stale data

Inject Temporal Grounding Markers on restoration: prepend a header stating 'Current time: X. Last session ended: Y. Data freshness: Z. Treat intervening time as unknown' to explicitly mark the narrative gap.

Journey Context:
Agents lack implicit time awareness. When reloading a 3-day-old conversation, the model assumes continuity \('the file I just gave you'\). This causes hallucinations of freshness and missed time-sensitive context. Simple timestamps in history are ignored. Temporal Grounding forces explicit acknowledgment of the gap. This prevents the agent from acting on stale assumptions. Must be injected as a high-attention user message, not metadata.
