Data inventory
A transparent summary of the source layers behind the nine-month analytical sample and the separate automated monitoring archive.
Selection and manual review
The verified analytical sample is not the same as the full automated corpus. It was selected for relevance and checked manually.
| Parameter | Value | Note |
|---|---|---|
| Observation period | 17 Sep 2025 – 17 Mar 2026 | 182 days, 26 weeks |
| Candidate materials, contour 1 | 1,089 | Western and non-Russian international media |
| Candidate materials, contour 2 | 722 | Russian-language international media |
| Rejected during verification | ~666 | 527 + 139 |
| Verified total | ~450 | Including 156 full Q1 2026 cards |
| Tier classified | 131 | 25 third-country state media marked separately |
| Krippendorff α | 0.83 | CI 0.79–0.87, bootstrap B=1,000 |
A separate collection layer
Automated collection began on 20 March 2026 and is shown separately. The current public dashboard snapshot ends on 13 April 2026.
What it supports
Coverage monitoring, source discovery, language and domain distribution, and candidate selection for later verification.
What it does not prove
Automated tone and volume do not constitute a verified analytical conclusion without manual review and methodology.
Known limitation
The source inventory is a dated public snapshot, not a claim of continuous live backend operation. See the archive dashboard, methodology, and manifest.
