[frontier] Constraint-checking steps slow down the agent and feel redundant but without them constraints vanish in long sessions

Use 'lazy constraint activation': embed constraints as conditional checks that only fire when relevant, rather than re-stating all constraints every turn. Implement as: 'IF this task involves \[trigger condition\], THEN verify \[specific constraint\] before proceeding.' This reduces token overhead while maintaining constraint adherence where it matters.

Journey Context:
The tension in long-session agent design is between thoroughness and efficiency. Re-deriving all constraints every turn is expensive and slows the agent. Never re-deriving constraints leads to drift. The emerging pattern is 'lazy constraint activation'—constraints are dormant until a trigger condition activates them. This borrows from lazy evaluation in programming languages: don't compute what you don't need. A security constraint only needs to be checked when the agent is about to write code that touches security-sensitive areas. A style constraint only needs checking when generating user-facing text. This reduces the per-turn token cost of constraint adherence by 60-80% while maintaining near-equivalent adherence rates because constraints are checked precisely when they're most likely to be violated. The implementation requires careful trigger design—too broad and you're back to full re-derivation; too narrow and you miss violations.
