StateWriteResult

Functions

write

Write all artifacts. Each file is staged to a sibling *.tmp.<pid>.<nanos> path, fsynced, then renamed into place, so an agent reading .context-bar/AGENT.md (or any brief) never observes a truncated mid-write file and the renamed bytes are durable on disk. Renames on the same filesystem are atomic on POSIX and Windows ReplaceFileW.
