Two-crate workspace added complexity without benefit for a solo project.
Library stays at src/, binary at src/bin/ranger/, tests at tests/.

 ## Key Design Decisions
 
 - **Keys**: jj-style random strings (16 chars, `k-z` alphabet). Reference by shortest unique prefix.
 - **Positioning**: Lexicographic string-based ordering within backlogs. Insert between two positions without renumbering.
+- **Single crate**: Library (`src/lib.rs`) and binary (`src/bin/ranger/`) in one crate. No workspace.
 - **Tasks in multiple backlogs**: A task can belong to multiple backlogs via `backlog_tasks` join table, with independent positions.
 - **Subtasks are tasks**: `parent_id` on tasks — subtasks get full task capabilities.
 - **No compile-time checked queries**: Using `sqlx::query_as` with runtime binding, not `query_as!` macros. No need for `DATABASE_URL` at build time.
-- **Dependencies unpinned**: `Cargo.toml` uses `"*"` versions; `Cargo.lock` pins exact versions.
 
 ## Testing
 
 Tests use `tempfile` for isolated SQLite databases. Each test creates its own DB — no shared state.
 
-The integration test (`crates/ranger-cli/tests/cli.rs`) exercises the full workflow via the compiled binary using `assert_cmd`.

 ## Architecture
 
-Ranger ships as three artifacts from one Rust codebase:
+Ranger is a single Rust crate with a library and binary target:
 
-- **Library** (`ranger-lib`) — core data model, database operations, key generation
-- **CLI** (`ranger-cli`) — clap-based binary for humans and AI agents
+- **Library** (`ranger`) — core data model, database operations, key generation
+- **CLI** (`ranger` binary) — clap-based binary for humans and AI agents
 - **Webapp** — for human use (planned)
 
 The CLI exists primarily so AI agents can manage tasks programmatically. The webapp exists for humans who prefer a visual interface.
