State ledgers beat bigger context windows for agent reliability
Boosting agent reliability requires a state ledger rather than larger context windows. The LedgerAgent system uses deterministic typed state and policy gates to improve reliability by up to 16 points without more LLM calls.

Your agent forgets things. The fix isn't a bigger context window. It's a state ledger. LedgerAgent proves it: deterministic typed state + a policy gate, zero extra LLM calls, up to 16-point reliability gains. arxiv.org/abs/2606.20529
