10-condition Africa-burden audit of the WHO ICTRP export computing a four-gate hiddenness funnel to Cochrane synthesis. Preregistration only at v0.0.1. # PACTR Hiddenness Atlas A 10-condition Africa-burden audit of the WHO ICTRP weekly export, computing a four-gate hiddenness funnel (PACTR registered → results posted → published → cited in any Cochrane MA) per condition. **Status:** implemented through v0.2.0 (four-gate funnel, NCT-bridge + PACTR-ID-literal Cochrane match, clustered-bootstrap CI, dashboard). Tag `prereg-v0.0.1` anchors the original protocol, frozen before any code was written. ## Headline question Of N PACTR-registered African trials in 10 high-burden conditions (TB, HIV, sickle cell, schistosomiasis, maternal sepsis, neonatal sepsis, snakebite, soil-transmitted helminths, cervical cancer, cholera), what fraction reach a Cochrane meta-analysis? Compares against the TrialScout CT.gov baseline (~63.6%) to quantify the African-evidence-to-global-synthesis gap. ## Design & preregistration protocol See `docs/superpowers/specs/2026-05-03-pactr-hiddenness-atlas-design.md`. A condensed paper-ready preregistration summary lives at `e156-submission/protocol.md`. ## Sister projects - **ARAC** — African representation *inside* Cochrane (Makerere PhD-cohort flagship). - **Hiddenness Atlas (CT.gov)** — same pattern, different registry. - **Trial-Truthfulness Atlas** — registry-coherence audit. - **malaria-ct-recon** — pilot scaffold this project clones. ## Reproducibility anchors - `prereg-v0.0.1` tag → frozen protocol; pushed before implementation. - OpenTimestamps Bitcoin anchor on the spec file → `docs/superpowers/specs/*.ots`. - Internet Archive snapshot → recorded in `.preregistration_commit.txt`. - ICTRP snapshot pinned by sha256 in `data/snapshots/ictrp_metadata.json` once preflight succeeds. ## License MIT.
