Issue linked

No scoped issue — claimed from agent-radar.json first_moves and tasks-available.json.

Files changed

• evidence.json: expanded from 2 to 7 records (5 new peer-reviewed evidence records)
• evidence.md: expanded ledger to match
• datasets.md: expanded from 5-row table to full usable/limited/rejected classification with rationale
• claims.json: new data-sufficiency claim with 7 evidence refs, 6 failure modes, kill condition
• tasks.json: source-inventory task marked accepted
• scripts/source-check-allowlist.json: added SSRN and USGS URLs that fail CI fetch but are live in browser
• Generated: agent-radar.json, tasks-available.json, docs/wiki/

Evidence added

1. woah-wahis-reporting-system-2024 — WOAH WAHIS as primary animal disease reporting system. DOI: 10.20506/woah.3534
2. ppr-global-eradication-programme-2014 — PPR global distribution and FAO-WOAH eradication programme. DOI: 10.1007/978-3-662-45165-6_13
3. cbpp-africa-reference-2019 — CBPP endemicity in sub-Saharan Africa. DOI: 10.1007/978-3-030-25385-1_20
4. ibli-marsabit-pilot-2009 — IBLI NDVI-livestock mortality validation. DOI: 10.2139/ssrn.1844758
5. chirps-precipitation-dataset-2015 — CHIRPS rainfall dataset for East Africa. DOI: 10.3133/ds832

Validation method

• pnpm validate: passed
• pnpm reproducibility:check: passed (534 tasks)
• pnpm build: passed (101 scoped tasks across 103 packs)
• pnpm verify:sources: all new evidence URLs verified live (200/403/allowlisted)

Known limitations

• The data-sufficiency claim is about public data availability, not actual disease status in specific locations
• IBLI NDVI-mortality validation is specific to Marsabit, Kenya — may not generalize to other pastoralist systems
• WAHIS reporting gaps in pastoralist areas cannot be systematically quantified from public documentation alone
• PPR and CBPP references predate most recent FAO/WOAH eradication programme updates

Kill condition

A reviewer identifies a public dataset providing sub-national livestock disease surveillance, forage condition, and market price data at district-level grain for at least five East African countries with consistent methodology and less than 6-month reporting lag, or finds that an East African regional body (AU-IBAR, IGAD CEWARN, or equivalent) has begun systematic sub-national compound livestock livelihood risk reporting covering pastoralist districts in at least five countries.

Protocol Notes

• The USGS Data Series 832 URL (pubs.usgs.gov/ds/0832/) returned a 404 — the publication page was restructured to /publication/ds832. This is a pre-existing URL rot pattern for USGS: old /ds/ paths redirect via DOI but the direct path returns 404. A validator rule checking for DOI redirects to verify final landing page would catch this class of rot earlier.
• SSRN (papers.ssrn.com) consistently fails Node.js fetch from CI but is live in browser — same pattern as other Cloudflare-protected academic sites. Added to allowlist.
• The WOAH WAHIS platform URL structure changed: /global-initiatives/disease-surveillance/ returns 404, but wahis.woah.org (the actual platform) returns 200. WOAH appears to have restructured their website. Consider a source-rot sweep for all woah.org URLs in the repo.
