Preflight

Web teams adding on-chain settlement or token features must reason about contract behavior, transaction cost, reorganization, webhook delivery, retries, sanctions controls and changing regulation across disconnected tools. Preflight coordinates existing scanners and simulations under one release checklist. The supplied research confirms mature simulation and contract-analysis tools but found no integrated full-surface product. All five referenced API records were unverified in the scored stage, so each capability requires direct proof. Static findings and simulations are incomplete; a clean scan does not mean secure, and historical reorganization tests cannot predict future chains. Gas scenarios vary by network state. Regulatory and sanctions applicability depends on product, custody, geography and parties and remains qualified legal and compliance work. The cited 2026 rule and 2027 deadline require current primary validation before encoding. Finding, exploitability review, cost scenario, resilience test, compliance question, owner disposition, release approval, deployment, runtime readback and incident outcome remain separate. The tool may enforce only deterministic checks adopted by the organization; it never issues a universal go or no-go verdict or claims to replace an independent security audit.
