incorrectly reported as server errors. Client-side errors and request
cancellations are now properly categorized for improved error tracking
and observability.

Platform packages

This directory contains infrastructure and cross-cutting technical concerns that are independent of Fleet's business domain. These packages provide foundational capabilities used across the codebase.

Platform vs domain

Following separation of concerns, we distinguish:

  • Platform (infrastructure): Technical concerns like database connectivity, HTTP utilities, middleware, and transport-level error handling. These packages have no knowledge of Fleet's business domain.
  • Domain (business logic): Feature-specific code organized into bounded contexts. Domain packages depend on platform packages, not the reverse.

Guidelines

  • Platform packages must not import domain packages
  • Platform packages should be general-purpose and reusable
  • Architectural boundaries are enforced by arch_test.go
