Yeachan-Heo d6a814258c Make Rust sessions easier to find and resume
This adds a lightweight session home for the Rust CLI, auto-persists REPL state, and exposes list, search, show, and named resume flows so users no longer need to remember raw JSON paths.

The change keeps the old --resume SESSION.json path working while adding friendlier session discovery. It also makes API env-based tests hermetic so workspace verification remains stable regardless of shell environment.

Constraint: Keep session UX incremental and CLI-native without introducing a new database or TUI layer

Constraint: Preserve backward compatibility for the existing --resume SESSION.json workflow

Rejected: Build a richer interactive picker now | higher implementation cost than needed for this parity slice

Confidence: high

Scope-risk: moderate

Reversibility: clean

Directive: Keep human-friendly session lookup additive; do not remove explicit path-based resume support

Tested: cargo fmt; cargo clippy --all-targets --all-features -- -D warnings; cargo test -q

Not-tested: Manual multi-session interactive REPL behavior across multiple terminals

Rust port foundation

This directory contains the first compatibility-first Rust foundation for a drop-in Claude Code CLI replacement.

Current milestone

This initial milestone focuses on harness-first scaffolding, not full feature parity:

  • a Cargo workspace aligned to major upstream seams
  • a placeholder CLI crate (rusty-claude-cli)
  • runtime, command, and tool registry skeleton crates
  • a compat-harness crate that reads the upstream TypeScript sources in ../src/
  • tests that prove upstream manifests/bootstrap hints can be extracted from the leaked TypeScript codebase

How to use

From this directory:

cargo fmt --all
cargo check --workspace
cargo test --workspace
cargo run -p rusty-claude-cli -- --help
cargo run -p rusty-claude-cli -- dump-manifests
cargo run -p rusty-claude-cli -- bootstrap-plan

Design notes

The shape follows the PRD's harness-first recommendation:

  1. Extract observable upstream command/tool/bootstrap facts first.
  2. Keep Rust module boundaries recognizable.
  3. Grow runtime compatibility behind proof artifacts.
  4. Document explicit gaps instead of implying drop-in parity too early.
