+   Why this runs at all: a directory the current rule cannot address holds work-log entries that no run will ever write, and nothing else reports them. "No pending content" and "pending content stranded under a name this rule cannot address" both reach the caller as success, so without this scan the entries stay invisible until somebody reads the directory by hand. Step 4 already adopts the one legacy shape that can be derived from `{HASH}`; this scan covers every shape that cannot.
