Request Lifecycle Tracer

Overview

Traces the complete lifecycle of an HTTP request or CLI command through all application layers — from entry point through middleware, handler, business logic, persistence, and back to response. Documents the full chain with data transformations at each step.

Tracing Process

Step 1: Identify the Request Entry

# Find route definition for the target endpoint
Grep: "#\\[Route\\(" --glob "**/*.php" -A 2
Grep: "Route::(get|post|put|delete)" --glob "**/routes/*.php"

# Find the handler for this route
# Read the route config or controller to identify the handler method
