Inspect a persisted walk-forward session — ledgr_walk_forward

These helpers reopen compact walk-forward evidence from the experiment store without recomputing, rerunning, or mutating stored artifacts.

Usage

ledgr_walk_forward_open(snapshot, session_id)

ledgr_walk_forward_scores(snapshot, session_id)

ledgr_walk_forward_folds(snapshot, session_id)

Arguments

snapshot: A sealed ledgr_snapshot locating the experiment store.
session_id: Walk-forward session identifier.

Value

ledgr_walk_forward_open() returns a ledgr_walk_forward_results list. Reopened sessions do not rehydrate live backtest objects in test_runs; that field contains linked test run_id strings. The reopened object includes the same programmatic degradation table fields used by print. ledgr_walk_forward_scores() and ledgr_walk_forward_folds() return tibbles.
