Logging

What it is

Logs explain execution and failure in operational terms.

When to use it

Use structured context and correlation IDs.

Syntax

event + actor ID + entity ID + request ID + safe reason

Example

Log::info("transfer.settled", [
    "transfer_id" => $transfer->id,
    "actor_id" => $actor->id,
    "request_id" => $requestId,
]);

Common mistakes

Logging everything increases cost and sensitive-data exposure; avoid ambiguous success messages.
