Package decoder 把不同编码（yaml/json/...）的字节流解码为统一的 map[string]any 中间表示。

Package discovery scans a configuration root and produces a stream of priority-ordered layers (base, overlays, extra overlay axes).

Package feature provides a tiny, allocation-light feature-flag / rollout evaluator that piggybacks on FastConf's strongly-typed configuration.

Package flog wraps *slog.Logger with a zerolog-style fluent API while preserving slog's handler ecosystem.

Package generator hosts FastConf's built-in contracts.Generator implementations.

Package mappath provides dotted-path helpers for map[string]any trees.

Package merger 实现 Kustomize 风格的 map[string]any 深度合并。

Package migration lets FastConf rewrite the merged map from one schema version to another before it is decoded into the strongly typed snapshot.

Package parser exposes the koanf-style Parser slot used at the Manager call site (WithSource(file.New(path), yaml.Parser())).

Package profile implements FastConf's tiny boolean profile-expression language (Phase 13).

Package provider abstracts external configuration sources (env, CLI, KV, Vault, ...).

Package source provides built-in contracts.Source implementations for the koanf-style WithSource(file/http/bytes, parser) call shape.

Package transform provides composable, post-merge / pre-decode transformations on the merged configuration tree.

Package validate hosts reusable validation primitives for FastConf.
