[frontier] When drift is inevitable which constraints should I protect first and how should I allocate re-injection budget

Explicitly rank constraints in a primacy stack: P0 for safety and legal constraints that must never compromise, P1 for core identity including role and persona, P2 for format constraints like output structure, P3 for preferences like style and tone. Allocate re-injection token budget and frequency proportionally: P0 constraints get the most frequent and verbose re-injection, P3 the least. When context pressure forces tradeoffs, allow P3 constraints to drift first.

Journey Context:
Not all constraints are equal, but most system prompts treat them as an undifferentiated list. When context pressure mounts, the model implicitly chooses which constraints to respect, and it will not choose the same ones you would. The constraint primacy stack makes this explicit and controllable. By ranking constraints and allocating re-injection budget accordingly, you control the drift gradient: P0 constraints are reinforced most frequently, P3 least. This is the 2025 evolution from writing a good system prompt to engineering a constraint hierarchy with explicit priority ordering and budget allocation. Teams running agents in production are finding that 3-4 priority levels is the sweet spot—more levels create management overhead without proportional fidelity improvement. The most common mistake is treating everything as P0, which is equivalent to having no priority system at all.
