auto-review:PR #1365 adds exactly one new Entity YAML at entities/en/enterprise-singapore.yaml via @oblygg-rgb's fork. The entity covers Enterprise Singapore's Startup SG Founder programme: a live, government-backed SGD 20,000–50,000 startup grant with 1:1 co-matching, sourced from authoritative first-party domains (startupsg.gov.sg, enterprisesg.gov.sg). Eligibility criteria, access route, lifecycle, consideration, terms URL, and four source IDs are all present and match the official sources without invented facts. Machine checks passed 3/3. The YAML is data-only with no code or generated output. All acceptance bullets are met. Real-world value is clear: this is a meaningful, active government programme that belongs in Sourcey's dataset.
