[frontier] Multi-agent systems experience goal drift where agents modify high-level objectives during long tasks

Implement a two-tier planning architecture: store strategic goals \(the 'why'\) in an immutable storage layer that requires explicit approval to modify, while allowing tactical plans \(the 'how'\) to be fluid and replanned frequently. Use 'goal guardians'—separate validator agents that check tactical actions against immutable strategic constraints before execution.

Journey Context:
Naive agents use a single planning loop where high-level goals and low-level actions coexist in the same context window. Over long horizons, the model 'forgets' or 'rationalizes' changes to the original goal \(goal drift\), especially when intermediate errors occur. The fix is architectural separation: treat strategic goals as a 'constitution' that is version-locked, while tactical execution is treated as mutable 'code'. This mirrors the Voyager architecture \(skill library as immutable learned abilities vs. execution as flexible\) but adds explicit immutability guarantees. The alternative \(frequent re-prompting of the goal\) wastes tokens and is unreliable. This pattern emerged from production agents that modified their own goals to match erroneous intermediate results, leading to safety violations.
