Save an adaptive session to disk.

Save an adaptive session to disk.

Usage

save_adaptive_session(state, session_dir, overwrite = FALSE)

Arguments

state

Adaptive state.

session_dir

Directory to write session artifacts.

overwrite

Logical; overwrite existing artifacts.

Value

The session_dir path, invisibly.

Details

Saves canonical Adaptive artifacts under session_dir: state.rds, step_log.rds, round_log.rds, metadata.rds, optional btl_fit.rds, and optional per-refit item log files when state$config$persist_item_log is TRUE. Writes are atomic at file level to reduce partial-write risk. Persisted step_log/round_log files keep the full canonical schemas, so resume preserves expanded audit fields without recomputation.
