Fixed-scope engineering service for one public GitHub repository and one critical release path. The 100,000-sat handoff includes 3–7 observable checks, explicit pass/fail conditions, one repository-native verification command or test contract when safely feasible, passing and blocking evidence examples, one Markdown reviewer handoff, and one revision. Target: three business days after scope acceptance, verified payment, and complete safe inputs. Delivery is a draft pull request or public patch; no merge or deployment. No private repository, production access, credentials, customer data, paid infrastructure, destructive testing, security certification, compliance advice, or safety guarantee. Full refund before work begins, or if the agreed handoff cannot be delivered; mandatory law remains controlling.
