Every quantitative benchmark published on edc-gezira.net is anchored to verifiable primary frameworks, including WHO SDG indicator 3.c.1 (44.5 skilled health workers per 10,000 population), WFME Basic Medical Education standards, and peer-reviewed COME/PBL literature. Interactive calculators execute entirely inside the user's browser with zero external API beacons or data storage.
1. Three-Tier Evidence Grading & Citation Rules
Medical education archives frequently conflate historical descriptive reports with active accreditation standards. To prevent ambiguity, edc-gezira.net enforces a three-tier evidence hierarchy across every English and Arabic page. Tier 1 comprises global normative thresholds published by the World Health Organization and the World Federation for Medical Education. Tier 2 comprises peer-reviewed longitudinal studies on Community-Oriented Medical Education (COME) and rural workforce retention. Tier 3 preserves historical workshop summaries and curriculum archives strictly inside collapsible reference drawers marked with their exact historical years.
In addition, legacy URLs rescued from third-party hijack periods (2013-2019) are isolated via HTTP 410 Gone responses at the Cloudflare edge and explicit Disallow directives across all crawler groups in robots.txt. Only verified academic and regional workforce topics are mapped to clean canonical routes.
| Evidence Tier | Permitted Sources | Presentation Standard |
|---|---|---|
| Tier 1 Normative | WHO Global / EMRO Workforce & WFME Standards | PRIMARY BENCHMARK |
| Tier 2 Peer-Reviewed | PubMed, BMC Medical Education, COME Literature | EVIDENCE SYNTHESIS |
| Tier 3 Historical Archive | 1978-2015 EDC Records & Workshop Logs | COLLAPSIBLE DRAWER |
2. Zero-Telemetry Interactive Workbench & Bilingual Parity
The Workforce Retention and Clinical Supervision Workbench runs using pure client-side JavaScript without third-party dependencies, cookies, or localStorage persistence. Catchment staffing values adjusted by medical school planners never leave the local browser session. Arabic mirror routes under /ar/ use native right-to-left (dir="rtl") document markup and self-hosted IBM Plex Sans Arabic typography so mixed-script text and quantitative SVG charts remain legible across desktop and mobile viewports.
