Constructor Details

#initialize(path, load_type: nil, decryption_key: nil, store: nil, dependency_chain: []) ⇒ Object

Loads a package directory or .cap file. Composite packages (metadata.dependencies, ARCHITECTURE.md section 4a) resolve against the package store given as store (directory path or Store) or via CAPSIUM_STORE. dependency_chain is internal: the ancestor GUIDs used for circular-dependency detection during recursive resolution.

#merged_view(exported_only: false) ⇒ MergedView

The merged content view across the storage layers (ARCHITECTURE.md section 5a); exported_only gives the dependent-package view (section 4a). Resolved dependencies act as read-only layers below all own layers.
