Proofline is an evidence gate for AI-assisted work. It translates a task contract into explicit requirements, checks fresh authoritative sources, stops on missing or contradictory evidence, and creates a deterministic proof packet before an external action can proceed. The public demonstration...

As answered by people managing Proofline by RELAUNCH DEPT. and JavaScript Tutorial.
Proofline by RELAUNCH DEPT.'s answer
Proofline separates doing work from proving that the work is ready. It maps every requirement to fresh, authoritative evidence, stops when sources are missing, stale, or contradictory, and creates a deterministic SHA-256 proof packet before an external action can proceed. A repair must be rechecked, and human approval remains a separate gate. The public demo and source let teams reproduce the decision instead of trusting a plausible completion message.
Proofline by RELAUNCH DEPT.'s answer
Proofline is for technical founders, AI-agent and automation teams, product and launch operators, and developers who need a reproducible decision record before an agent publishes, pays, deploys, or reports completion. It is especially useful when a workflow depends on several sources that can disagree or become stale.
Proofline by RELAUNCH DEPT.'s answer
Proofline uses Python, FastAPI, Google Agent Development Kit (ADK), Gemini, and Google Cloud Run. It produces deterministic JSON and SHA-256 proof packets and includes focused automated tests. The public GitHub repository documents the architecture and reproducible checks.
Proofline by RELAUNCH DEPT.'s answer
Proofline began after seeing AI workflows produce convincing completion reports even when decisive evidence was stale, contradictory, or missing. Its first public example turns a conflict between a 24-hour launch promise and a 48-hour checkout promise into an explicit STOP, repair, recheck, and human-approval sequence.
Proofline by RELAUNCH DEPT.'s answer
Choose Proofline when the requirement is not observability alone but evidence that a specific task contract is satisfied before an external action. It focuses on requirement-to-evidence mapping, freshness and contradiction checks, deterministic receipts, and a separate human-approval gate. The public source and demonstration make that boundary inspectable. It is a focused prototype and service, not a claim to replace full observability or evaluation platforms.
