Yeachan-Heo 8465b6923b Preserve actionable state in compacted Rust sessions
This upgrades Rust session compaction so summaries carry more than a flat timeline. The compacted state now calls out recent user requests, pending work signals, key files, and the current work focus so resumed sessions retain stronger execution continuity.

The change stays deterministic and local while moving the compact output closer to session-memory style handoff value.

Constraint: Keep compaction local and deterministic rather than introducing API-side summarization

Constraint: Preserve the existing resumable system-summary mechanism and compact command flow

Rejected: Add a full session-memory background extractor now | larger runtime change than needed for this incremental parity pass

Confidence: high

Scope-risk: narrow

Reversibility: clean

Directive: Keep future compaction enrichments biased toward actionable state transfer, not just verbose recap

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

Not-tested: Long real-world sessions with deeply nested tool/result payloads

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.
