Provides a generic cache interface with memory and Redis backends, supporting TTL-based FetchOrSave with singleflight deduplication. The codec layer handles serialization/deserialization. This module is self-contained and can be extracted for any Go project needing a pluggable cache with deduplication.

Implements a retry utility with configurable exponential backoff, jitter, and abort conditions. Supports both synchronous and asynchronous operations. The interface is clean and dependency-free, making it reusable across any Go application requiring resilient retry logic.

A family of selector implementations (doublestar glob, label, severity, signature) for filtering artifacts based on metadata. Each selector implements a common interface and can be registered dynamically. This pattern is reusable for any system needing pluggable filtering criteria, such as retention policies or access control.

Defines the event building and publishing pipeline for Harbor's notification system. Events are constructed with metadata resolvers and dispatched to handlers (webhook, Slack, audit log). The pattern decouples event producers from consumers and supports asynchronous processing. The interface is generic and could be adapted for other event-driven systems.

A lightweight ORM layer built on Beego that provides model registration, metadata parsing (table names, columns, relations), and query building with snake_case conversion. It includes transaction support via PostgreSQL savepoints. This module encapsulates ORM boilerplate and can be reused in any Go project using Beego or similar databases.

A generic query abstraction supporting keywords, sorting, pagination, range filters, OR lists, and fuzzy matching. It is used across the codebase for API query parameters. The module is self-contained and can be extracted for any Go project needing a flexible query DSL.
