State
State is a working note an agent leaves for its own next run. It is not curated memory and it is not a log: it's the small blob of "where I got to" that lets run N+1 continue rather than restart.
Its effect on behavior is continuity. A stateless agent starts from zero every time, which makes each run independent, reproducible and easy to reason about — and means it cannot resume a partial job, cannot track a value across days, and will re-open the same question every morning. A carry-forward agent can, at the price of one run's mistake becoming the next run's premise.
That last part is the honest cost. Errors compound in state in a way they do not in a stateless agent. A wrong number written into a working note travels forward until something contradicts it.
State in this deployment

| Stateless | Every run starts fresh. The default — nothing is carried from the previous run. | available · default |
| Carry forward | The agent leaves itself one short memo at the end of a run and reads it at the start of the next — so a scheduled agent picks up where it left off. | available |
How to choose
Stateless is the default and the right answer for anything that reports current state — availability, prices, whether a thing is open. Every run of that agent should be able to stand on its own.
Carry forward when the job is genuinely multi-run: watching a value change, working through a list too long for one run, or picking up where a previous run was cut off. The test is whether run N+1 would do something different if it knew what run N had done.
If you turn it on, read the carried note occasionally. It is the one part of an agent that can quietly go wrong and stay wrong, because nothing in the next run is obliged to re-check it.
There is no automated experiment runner yet. Nothing here sweeps this axis for you — changing it means editing the agent and reading the next run. A compare mode that runs one task across several compositions is named on the index as not built, and that is still true.
