 "method_note": "publication-cadence watch: each surface reports the latest release visible from this vantage, scored as days-since against its own nominal cadence (business-day basis for daily series, so weekends are not darkness; Chinese public holidays are not modelled and appear as short recurring spikes the detector's reference learns). NBS series additionally carry days_past_promise, scored against the state's own published release calendar — a promise date is sharper than a learned rhythm. darkness_index is the mean staleness ratio over surfaces that answered. A surface that could not be fetched is listed as unreachable and excluded — vantage trouble is not withholding (nra.gov.cn in particular is known to gate some foreign vantages). A high index states that official surfaces are late against their own rhythm; it does not establish intent",
