A controlled path from input to execution.

The diagram described here is a public conceptual model, not a certification of production availability, regulatory status or fault tolerance. Public documentation can explain intended responsibilities and interfaces; it cannot prove that a control fired correctly in a particular live event. That requires environment-specific logs, tests and operational review.

IMRYN therefore treats architecture claims and performance claims as separate questions. A well-structured system can still lose money, receive bad data, encounter market gaps, or fail operationally. Conversely, a favourable result does not demonstrate that the underlying controls are adequate.

Signals may be derived from market observations, model outputs or rule-based strategies. Whatever their origin, they should be represented as proposals with context—not as permission to trade. The decision record should preserve the input timestamp, strategy or model version, intended instrument, direction, size request and any confidence or eligibility conditions used at that moment.

This separation makes a practical distinction between “the strategy proposed an action” and “the system accepted an order.” It also gives reviewers a stable point from which to investigate data staleness, version changes, conflicting signals or unexpected behaviour.

A risk gate is a separate decision boundary. Its job is to compare a proposed action with current exposure, instrument eligibility, account state, venue state and configured limits. A rejection is a valid system outcome; the system should not silently relax a limit merely because a strategy repeats the request.

Limits reduce selected risks but do not remove market, liquidity, model, counterparty or operational risk. Their settings also need governance: who can change them, when a change becomes active, how it is tested and where the previous value is retained.

Execution venues expose different order types, identifiers, state transitions and failure messages. A venue adapter should translate an accepted internal instruction into the venue-specific request while retaining the relationship between the proposal, the submitted order and every acknowledgement or fill.

Timeout does not necessarily mean rejection, and a successful request does not necessarily mean a fill. For that reason, retries cannot be treated as harmless by default. The adapter and reconciliation layer need an idempotency or duplicate-control strategy appropriate to the destination.

Monitoring should answer whether the system is receiving current inputs, evaluating proposals, enforcing controls, communicating with its destinations and reconciling outcomes. Alerts should carry enough context to support a decision, while durable records should make later review possible.

Human oversight is not a decorative approval label. It requires a clear stop path, access boundaries, an escalation owner and a way to verify what happened after intervention. The public architecture intentionally does not disclose sensitive credentials, thresholds or venue configuration.
