Crate dream 

dream

Layer 2 library facade that re-exports all Layer 0–1 core crates under feature-gated modules. Zero own logic — every public item originates from a core crate.

Responsibility Table

File/Dir	Responsibility
Cargo.toml	Crate manifest: seven feature-gated optional workspace deps
src/lib.rs	Feature-gated pub mod re-exports + crate-level Feature Flags table
docs/	Crate doc entities: aggregation feature spec and zero-own-logic invariant
tests/	Integration smoke tests verifying re-export paths per feature

Feature Flags

Feature	Activates	Description
common	claude_core	Path topology (ClaudePaths) and process utilities
storage	claude_storage_core	Zero-dep JSONL parser for ~/.claude/ storage
profile	claude_profile_core	Token status detection and account credential management
runner	claude_runner_core	ClaudeCommand builder for programmatic Claude Code execution
manager	claude_version_core	Version detection, settings I/O, and install helpers
full	all five above	All domain modules in a single dependency
enabled	full	Alias for full; conventional workspace activation name

Usage

# Cargo.toml
[dependencies]
dream = { version = "~1.0", features = ["profile", "runner"] }

use dream::profile::token::TokenStatus;
use dream::runner::ClaudeCommand;

Architecture

Layer 2 facade — depends on Layer 0 (claude_core) and Layer 1 (claude_profile_core, claude_runner_core, claude_version_core) plus the out-of-hierarchy claude_storage_core. No dependency on any Layer 2 CLI crate or Layer 3 super-app. No own types, traits, functions, or error definitions. dream — feature-gated facade re-exporting all claude_* core crates.

Enable individual domain modules via Cargo features:

Feature	Module	Activates
common	[common]	claude_core — ClaudePaths, process utilities
storage	[storage]	claude_storage_core — JSONL parser, session types
profile	[profile]	claude_profile_core — token status, account management
runner	[runner]	claude_runner_core — ClaudeCommand builder + execute()
version	[version]	claude_version_core — version, settings I/O helpers
assets	[assets]	claude_assets_core — symlink-based artifact installer
full	all	All six domain modules
enabled	all	Alias for full

Usage

[dependencies]
dream = { version = "~1.0", features = ["profile", "runner"] }

use dream::runner::ClaudeCommand;
