January 2026 monthly summary for developer work: Delivered targeted enhancements to API documentation and error handling for serial number validation across two repositories, aligning client expectations with API behavior and reducing integration ambiguity. Key work includes adding explicit serial number validation error codes to the API docs (moysklad/api-remap-1.2-doc-in) and improving API error handling documentation for serial number validation (moysklad/api-remap-1.2-doc). These changes were implemented via three commits contributing to MC-78786, strengthening developer experience and supportability. Impact: clearer error semantics, faster onboarding for integrators, and a more maintainable docs surface. Technologies used: API documentation tooling, error-code taxonomy, and version-controlled documentation across two repos.

Implemented new serial-number validation error codes and updated user-facing messages, and synchronized documentation and changelog entries between the public API docs and internal-in docs to support faster integration and fewer support tickets.
