February 2026 HMIS monthly performance snapshot for repository hmislk/hmis. Focus was on delivering high-value features, improving API surface and governance, and enhancing reliability and UX across pharmacy and hospital modules. Key work includes a department-wide stock reporting feature, a major API expansion for Institution/Department/Site management with extensive docs, robust API testing, a cross-cutting audit-logging overhaul, and startup telemetry to capture accurate restart times. Top achievements and their commit references: 1) Department Vice Stock Report delivery (commit 9a1de603ee1a746253554387106a2fdca9b5e3b2) – Created Department Vice Stock DTO, added controller logic, built a XHTML report page with export options (PDF/Excel/Print), navigation, and JPQL-driven aggregations with footer totals. Business value: provides a consolidated, auditable stock view by department/institution/site enabling faster, data-driven decisions and compliance-ready reporting. 2) Institution, Department, and Site Management APIs (commit 4e4bef58e70d8d0781002d25b2376b8eec399bce) – Full CRUD APIs with validation, relationship management, and comprehensive documentation (API guide + implementation summary). Delivered 26 new files (15 DTOs, 4 services, 3 REST endpoints) and ready for testing. Business value: scalable, consistent infrastructure for institutional configuration and governance. 3) API Testing – All tests pass for the new APIs (commit 4a8405493cfc1376d33d5e0d1dddffbfcd98aa09) – 11/11 endpoints verified; issues fixed (e.g., SiteDTO constructor) and guidance for production readiness. Business value: increased reliability and faster release cycles. 4) Audit Logging across phases – Completed audit logging across all phases (commit 2c09151203abc31ec24a999dceffbb57423837be) with UI enhancements and secure, detailed event tracing; includes per-entity audit maps, UI cues, and improved validation/error feedback. Business value: better traceability, regulatory compliance, and post-incident forensics. 5) Restart time telemetry – Implemented eager startup time capture and exposure via VersionController (commit 0f84b165af9b27199db030d77434d39c2515dc79) and ApplicationStartupTimeService; UI updated to show Last Restart Time. Business value: accurate restart metrics support uptime monitoring and faster incident response. Notes: - Additional UX and reliability improvements were shipped in this period, including startup log cleanup, error messaging enhancements, and continued alignment of DTO-based UI patterns across critical components.
