Check whether a run directory is finalized

A finalized run cannot have its methodology silently re-declared. Per AC5 (soft-lock with audit trail; methodology change creates new run), callers check this flag before mutating methodology-affecting state on a prior run; if TRUE, they fork via clone_run_with_new_mode.

Usage

is_run_finalized(run_dir)

Arguments

run_dir

Path to a run output directory.

Value

Logical scalar.

Details

Returns FALSE for a missing run_metadata.json – "no metadata" means "not finalized" by definition (the canonical record doesn't exist yet, so no claim has been made).
