remove path `{dotted}` not found, skipped

Error message

remove path `{dotted}` not found, skipped

What it means

Soft-failure path in remove_from_item: a remove rule with a string dotted path was applied to a mapping item, parse_dotted_path/remove_at walked the path, but the target key was not found. The item is kept unchanged and a StepLogEntry::warn is recorded instead of erroring — matching legacy parity where removing a non-existent path is a no-op warning, not a failure of the overlay step.

Solutions

1. Check the dotted path spelling and nesting against actual item contents
2. Make removal conditional via `when` so it only targets items that have the key
3. Treat the warning as benign if the key is expected to be optionally absent
4. Use logging output to list skipped paths and correct them

Example fix

// before
remove: ["udp-x"]
// after
remove: ["udp"]

if let Some(ConfigValue::Object(item)) = items.first() {
    for path in ["udp"] {
        if !item.contains_key(path) {
            eprintln!("remove path `{path}` absent from items; fix or make conditional");
        }
    }
}

When it happens

Trigger: A `remove: ["a.b.c"]` entry where key `a.b.c` does not exist on the matched item.

Common situations: Typos in removal paths; paths valid in one core/profile version but absent after schema changes; items that vary in shape so some lack the key.
