citable_censorship = censorship/mixed incidents excluding suspected/draft. citable_with_evidence = the subset with >=1 linked evidence permalink (the individually-verifiable count). citable_multi_source = the subset corroborated by >=2 independent sources. The remainder are single-source historical-backfill rows.

The source category, individual evidence links and multi-source corroboration are different properties. Open the incident before citing its evidence.

Source-window days / measurements

30 / 459,418

derived: sum of countries[].samples (OONI measurementCount) over the rolling 30-day live window. Not floored, not padded, not a constant.

Newest per-country ingestion stamp — the only field here that can go stale. `dateModified` and `generated_at_utc` are serve times, minted per request; do not read them as data freshness.

Cross-country LOCO MEAN F1 0.711, which /v1/classifier/info names as its headline_metric; the median 0.870 is dominated by small-sample countries and is not the honest single number. 0.63 on the 61 countries with n>=30. Forward-temporal holdout AUC 0.669 / F1 0.474 — generalizes across countries, degrades across time (retrained weekly). The retired v2 (0.998 F1) had country-tier leakage; not cited as live.

Turkmenistan was served as rank 1 / score 50 / high in the CSV on 2 measurements; its shrunk score is 8 / free. 12 scores, 3 levels and 124 ranks disagreed between the two files. Both are now computed once. NO SCORE OR LEVEL MOVED UPWARD IN EITHER FILE — verified against the full live 130-country corpus. BOTH distributions changed, not only the CSV: the CSV s scores and levels moved down, and the JSON s `rank` changed for 108 of 130 rows because ties on the rounded score used to be broken by upstream array order. See `changedFields` for the per-distribution breakdown. A consumer that stored `rank` from EITHER file should re-fetch."

The original report called this a composite of block rate, category breadth and consistency. The actual scoring definition above belongs to the retrieved index; its window and methods can differ from historical report text.

Collection documentation

• The original page describes roughly 1,100 distinct domains per day from a 5,154-domain pool across 130 countries. Its node count was a build-time constant, not a verified active roster.
• It describes OONI ingestion for eight test types across 130 countries every six hours; CensoredPlanet DNS/HTTP/S data across 50 countries; and continuous IODA ASN-level outage alerts.
• These are documented source/configuration descriptions, not fresh coverage or delivery checks. Read the current probe roster and source dates before quoting them.

Classifier v3.3 reference

GradientBoosting: LOCO mean F1 0.71 across 127 countries; 0.63 on the 61 with n≥30. The 0.87 median is inflated by 46 small-sample countries at a perfect 1.0. Training used 4,237 labelled samples, including 1,116 positive samples across 131 countries.

Shutdown-risk reference

The original shutdown_risk_v9 evaluation reports forward country-ranking AUC 0.90 against Access Now KeepItOn shutdowns. It ranks which countries; within-country day timing AUC is 0.33, below chance. These are not the distinct Atlas honest_forecast_v1 event model's scores.

The original page describes cross-source correlation and an incident-generation schedule every 30 minutes. A documented schedule is not proof that each run succeeded, and correlation is not independent confirmation of every incident.
