 - **Match value / `matchValue()`**: the value to match comes from `-m/--match` or, if that is empty, an optional positional argument. The positional fallback exists because pflag does not attach a space-separated value to a string flag grouped with a bool flag, so in `-pm k8s` the `k8s` arrives as a positional. `-m` still wins when both are given.
 - **`queryPuppetDB(url, query)`**: takes the URL as a parameter — never reads globals.
 - **`processResults()`**: iterates facts, returns sorted `"certname value"` strings. JSON string values are unquoted; other JSON types rendered as compact JSON.
-- **Output modes**: JSON (`-j`), count (`-C`), Ansible YAML (`-A`), node-only (`-1`), value-only (`-2`), default (node + value).
+- **Output modes**: JSON (`-j`), count (`-C`), Ansible YAML (`-A`), node-only (`-1`), value-only (`-2`), default (node + value). `-j` and `-A` share `factsByHost()`, so both attach the queried fact(s) per host — as an object under the host (`-j`) or as inventory host vars (`-A`).
 - **Stdin support**: `stdinReader()` reads node names from stdin only when it is a real pipe/redirect carrying data (and no `-n` given). Terminals, `/dev/null`, and empty/closed pipes fall through to a normal query — so running without a TTY (e.g. invoked by an agent or CI) behaves like an interactive run instead of consuming empty input.
 - **SIGPIPE handling**: `signal.Ignore(syscall.SIGPIPE)` so pipes to `head` etc. work cleanly.
