Report #3517

[agent\_craft] All context is treated as equally important, so critical constraints drift out of attention

Maintain a pinned 'invariants' block at the top of the context that restates hard rules, active constraints, and the current goal in the agent's own terse voice. Refresh it explicitly when scope changes.

Journey Context:
Without a pinned summary, the model's behavior is shaped by whatever happened most recently in the conversation. A constraint stated twenty turns ago effectively ceases to exist. A goal stated at the start gets reinterpreted. The fix is not longer prompts but a deliberately managed working memory: a small block that is always in the prefix and is updated by the agent itself after meaningful state changes. This block should use imperative, testable language, not vague intentions. The tradeoff is that it consumes a fixed token tax on every turn, but that tax is smaller than the cost of rediscovering or violating the constraint.
