Validate an adaptive session directory.

Validate an adaptive session directory.

Usage

validate_session_dir(session_dir)

Arguments

session_dir

Directory containing session artifacts.

Value

A metadata list containing at least schema_version, package_version, and n_items.

Details

Verifies that required session artifacts exist and that serialized logs match canonical schemas for step_log and round_log. This check is intended as a preflight for load_adaptive_session() and enforces the canonical adaptive session metadata shape. Validation is strict: added/removed/reordered columns in persisted logs are treated as schema incompatibilities and abort resume.

Examples

dir <- tempfile("pwllm-session-")
state <- adaptive_rank_start(c("a", "b", "c"), seed = 1)
save_adaptive_session(state, dir, overwrite = TRUE)
validate_session_dir(dir)
