A2A Exception Triage Console

The A2A Exception Triage Console provides deterministic rule-based triage for payment failures across FedNow, RTP, SEPA Instant, PIX, and tokenized rails. It helps treasury operations teams diagnose ISO 20022 and NACHA error codes locally and generate machine-readable recovery workflows.

How it works: Paste a raw exception log and the tool sanitises PII via regex, extracts error codes, and cross-references an embedded Decline Code Matrix (15+ entries) and Rail Capability Matrix. A deterministic ReAct loop (THOUGHT → ACTION → OBSERVATION) traces the resolution path and produces a structured recovery card with confidence score. Output can be exported as a LangChain / AutoGen / CrewAI-compatible system prompt.

All logic runs as plain JavaScript in your browser — no machine learning models, no external API calls. Outputs are generated deterministically from embedded rule sets and knowledge bases.

Export: Results can be downloaded as JSON or Markdown for use in downstream workflows, agent runtimes, or audit documentation.

Limitations: This tool is a reference aid and simulation environment. It does not constitute legal, financial, or compliance advice. Always verify outputs with qualified professionals before acting on them.

This tool runs entirely in your browser. No data is transmitted to any server. All inputs, calculations, and generated outputs are processed locally on your device. fetch() and XMLHttpRequest are overridden at runtime to block all outbound network calls.

No analytics, no cookies, no telemetry, no tracking pixels. This tool does not collect, store, or transmit any personally identifiable information (PII), financial data, or organisational data. Any state you choose to save is stored exclusively in your browser's localStorage and never leaves your device.

This tool is part of the AINumbers.co Rule-Based Engine Suite — a collection of privacy-first, client-side fintech intelligence tools for tokenized A2A infrastructure and CBDC frameworks.
