Report #103356

[frontier] Long-running agents lose progress and drift when context windows fill, connections drop, or a single failure kills the whole monolithic loop.

Use a managed agent runtime with durable sessions, explicit checkpoints, append-only event logs, and scoped permissions; restart from the last checkpoint rather than replaying the entire transcript.

Journey Context:
Anthropic's long-running Claude and Managed Agents decouple the model, orchestration, execution environment, and session log. This lets hours-long tasks survive disconnects and avoids piling the entire history into the model context. The pattern is becoming the production default in 2026; self-built loops often miss it and fail at context-window limits.
