PromiseGap is an autonomous contract and technical specification cross-examination platform built for the Meta AI Hackathon, powered by Meta Muse Spark (muse-spark-1.0) and Muse Spark Vision. In enterprise software development and complex corporate procurement, sales teams frequently make aggressive contractual promises (SLA commitments, delivery dates, data ownership) that internal technical specifications or engineering teams quietly contradict. PromiseGap acts as an intelligent, automated guardian, instantly cross-referencing sales proposals against technical documents to expose critical hidden discrepancies before contracts are signed. Key Features Demonstrated in this Video: Instant Guest Demo (0:00 - 0:37) : Automatically cross-examining sales proposals against technical specs to flag high-risk SLA and delivery discrepancies, generating an immediate comprehensive risk score of 78 out of 100 with side-by-side quote comparisons. Multimodal Vision & OCR (0:37 - 1:22) : Ingesting and auditing scanned contract images (.png files) from both clients and providers using advanced OCR and Live Vision reasoning, ensuring legacy paperwork and physical scans are seamlessly processed. Custom PDF Audit (1:22 - 1:53) : Catching critical, high-stakes contradictions across full-length PDF documents (e.g., commercial proposals claiming 99.99% uptime and zero data loss, countered by technical specifications enforcing a 99.5% ceiling and a 4-hour RPO). Engineering Rigor & Telemetry (1:53 - End) : Live CLI diagnostics proving direct, unbuffered API connectivity to Meta Muse Spark 1.0 with real-time budget and token telemetry, backed by an elite benchmark suite achieving a 100% F1-score across 24 ground-truth test scenarios and 43 passing PHPUnit tests. Architecture & Tech Stack: Core Engine & Backend: PHP 8.2, Symfony framework, EasyAdmin interface, and AssetMapper (Tailwind CSS / DaisyUI) for clean, zero-dependency production builds. AI & Multimodal Integration: Direct integration with Meta Muse Spark (muse-spark-1.0) and Muse Spark Vision for semantic reasoning, document parsing, and strict cross-examination logic. Infrastructure & Testing: Containerized via Docker Compose, validated through a rigorous automated Eval Suite and 100% passing PHPUnit test coverage. PromiseGap bridges the dangerous gap between commercial commitments and engineering reality, bringing absolute transparency and automated risk mitigation to enterprise legal and technical workflows.
