# Verification record — `rs/apr/jrpps-pr-sole-proprietor-registration` v1.0.0 This file is the **source-review record** for this document version, per the `manual-source-review-v1` practice. ## Current claim - **`status`:** `draft` - **`verification.method`:** `manual-source-review-v1` - **`verification.lastVerifiedAt`:** `2026-07-13` - **`maturity.level`:** `structural-reference` This is GovSchema Standard Research cycle **GOV-2725** (parent research cycle **GOV-2723**), authoring the child issue named in **GOV-2716**'s own cycle: **GOV-2716** scouted Serbia (via APR's JRPPS-PR sole-proprietor registration) to a strong, ready-to-author candidate and logged it in `CATALOG.md`'s "Known Gaps & Opportunities" section rather than authoring it immediately.

This cycle's own re-fetch found the **live host fully down**, not merely flaky: - A retry loop of the source PDF URL directly (`https://apr.gov.rs/upload/Portals/0/preduzetnici/2025/JRPPS_PR___Osnivanje_2025_T.pdf`) returned **HTTP 500 on all 23 consecutive attempts** (spread across two batches, with 3-5s backoff and a browser-like `User-Agent`), each time returning the same 39,174-byte generic IIS/ASP.NET error page (confirmed by inspecting the response body, which begins `
