Research is a workflow.
Execution is a state machine.
An engineering framework for controlled data ingestion, reproducible analysis and measurable order handling.
Every boundary has a contract.
Conceptual system map, not a claim of production trading activity or institutional connectivity.
Failure modes belong in the design.
A serious financial system assumes that clocks drift, messages duplicate and counterparties sometimes fail.
Point-in-time data
Source identifiers, immutable observation timestamps, schema contracts, stale-data flags and deterministic replay.
Risk and execution controls
Pre-trade validation, idempotent order transitions, cancel acknowledgement, throttles and explicit circuit-breaker behavior.
Observability and accounting
Traceable decisions, latency distributions, rejection classification, post-trade reconciliation and escalation rules.
Reproducible delivery
Versioned inputs, test fixtures, deployment gates and operational separation between research and production environments.
