OptionalpipelineOptionalinitialState?: Record<string, unknown>The subflow's OWN fold base — the state its isolated runtime started
from, before its first commit. The sibling of
RuntimeSnapshot.initialState, carried here so a subflow's history
can be folded offline exactly like the run's log (stateAt,
timeTravel(...).drill(mount)). Frozen and detached.
Normally {}: a subflow's inputMapper seed is itself the first
COMMIT in history (the root context commits it), not a pre-run base.
Optional ReadonlylogAddress?: LogAddressIdentity of the local history, not its parent's log.
Optional ReadonlyreadSources?: EngineReadSourcesNative source book for this invocation's own log. Memory observation only; no parent receipt applies.
The subflow's final state. The traverser's record holds the LIVE heap — what a plain
getSnapshot()and the checkpoint see. UndergetSnapshot({ redact: true })the executor serves the subflow's own redacted mirror here instead (9.20.0;handlers/servedSubflowResults), which is exactly whatstateAtfoldshistoryto.
