/**
 * Configurable thresholds for log10x_investigate.
 *
 * Defaults match the spec. Overrides load from a JSON file pointed at by
 * LOG10X_THRESHOLDS_FILE at process startup — the file is merged against
 * the defaults, so users only need to specify the keys they care about.
 *
 * Future: the canonical source is the Receiver policy file (git-versioned,
 * PR-reviewed) alongside the mute entries. Wire that once the Reporter
 * config-read path exists.
