Summary

  • Set up 4-crate Cargo workspace (app, backend, frontend, contracts) with centralized [workspace.dependencies], inter-crate dependency rules, and edition 2024
  • Implement contracts crate with all shared domain types: orchestration (Project, Thread, Turn, Message, Checkpoint, ReadModel), git types (GitStatus, FileDiff, DiffHunk), terminal status, and keybindings (KeySpec with parse/format)
  • Add justfile with qa, fmt, clippy, test, ci-setup, ci-build, ci-package recipes
  • Add .forgejo/workflows/qa.yml CI pipeline (rust:1-bookworm + GTK4 dev libs)
  • Add CLAUDE.md with architecture, structure, conventions, and AI agent workflow guidelines

Test plan

  • just qa passes (format check + clippy 0 warnings + 12/12 tests)
  • All 4 crates compile (cargo check succeeds)
  • Contracts crate: serde round-trip tests for all key types
  • Contracts crate: KeySpec parse/format tests
  • Inter-crate rules verified (backend has no GTK deps, frontend has no sqlx/git2, contracts is lightweight)

Closes #1
Closes #2

Set up the 4-crate workspace (app, backend, frontend, contracts) with
centralized dependency management, inter-crate rules, justfile with
qa/ci recipes, Forgejo Actions CI pipeline, and CLAUDE.md.

Implement the contracts crate with all shared domain types: orchestration
(Project, Thread, Turn, Message, Checkpoint, ReadModel), git types
(GitStatus, FileDiff, DiffHunk), terminal status, and keybindings
(KeySpec with parse/format). Includes 12 unit tests.

🔍 Chaman review — REQUEST CHANGES

Overall the scaffold is solid: workspace structure, contracts types, serde round-trip tests, justfile recipes, and CI wiring all look good against the acceptance criteria in #1 and #2. Two blocking issues before merge.

❌ .forgejo/workflows/qa.yml line 13 — unstable container image

image: rust:1-trixie

trixie is Debian testing — a rolling target that can break without notice when packages change. The org convention (and every other project here) uses rust:1-bookworm (Debian stable).

Fix: change to image: rust:1-bookworm

❌ crates/frontend/Cargo.toml line 10 — frontend → backend coupling violates acceptance criterion

forge-agent-backend = { path = "../backend" }

This transitively pulls sqlx, git2, and portable-pty into the frontend compilation unit — exactly what issue #1's acceptance criterion forbids: "frontend does not depend on sqlx or git2".

The intended crate graph is:

contracts  ←  backend
contracts  ←  frontend
backend + frontend  ←  app      ← app is the wiring point

crates/frontend/src/ipc_client.rs is currently just a comment stub pointing to issue #6 — it imports nothing from backend. Drop the forge-agent-backend dep from frontend/Cargo.toml now and re-introduce it in issue #6 when the actual IPC channel types exist. If frontend ends up needing AppCommand/AppEvent from backend::ipc, the correct resolution at that point is either to move those types into contracts or have app do the wiring — not to couple the two subsystem crates directly.

Fix: remove forge-agent-backend = { path = "../backend" } from crates/frontend/Cargo.toml

❌ Project-specific system deps belong in just ci-setup, not the workflow.

The global CLAUDE.md convention is: "workflow files should be identical across all projects (only container.image: varies); everything project-specific lives in the justfile." Installing libgtk-4-dev, libadwaita-1-dev, libvte-2.91-gtk4-dev, libgtksourceview-5-dev here makes this workflow non-generic.

The nodejs install must stay first (needed before checkout for JS-based actions), but the GTK dev libs should move into just ci-setup (x86_64 branch).

Fix: Keep only nodejs in this step; add the GTK dev libs to the ci-setup recipe in the justfile:

apt-get update -qq

Review: feat/scaffold-and-contracts

Closes #1 and #2. All acceptance criteria are met: 4-crate workspace compiles, workspace deps are complete, inter-crate rules are enforced in Cargo.toml, CI workflow follows the standard naming convention, CLAUDE.md covers all required sections, and the contracts crate has every type specified in both issues.

One correctness bug in KeySpec::parse needs fixing before merge.

Issue #1 checklist — all ✅

Issue #2 checklist — all ✅ including OrchestrationReadModel, all git types, TerminalStatus, and KeySpec parse/format. The serde_json::Value in MessageContent::ToolCall is the correct reason serde_json appears as a contracts dep; MessageContent correctly derives PartialEq only (not Eq) because f64 inside Value is not Eq — fine.

CI — rust:1-trixie is intentional for GTK4 package availability; nodejs is installed before any JS-based actions; just is fetched from a pinned release URL (not via install.sh); cache key on Cargo.lock. All good.

One bug to fix before merge — see inline comment.

Bug: empty key name is silently accepted.

s.split('+') on an empty string yields a single empty token ""; on "Ctrl+" it yields ["Ctrl", ""]. Neither matches a modifier, so the catch-all arm runs with k = "", setting key = Some(""). The function then returns Some(KeySpec { key: "", ... }) instead of None.

This means:

KeySpec::parse("")        // → Some(KeySpec { key: "", ctrl: false, … })  ← wrong
KeySpec::parse("Ctrl+")   // → Some(KeySpec { key: "", ctrl: true,  … })  ← wrong

Fix — reject empty tokens in the catch-all:

k if !k.is_empty() => key = Some(k.to_string()),
_ => return None,   // empty token means malformed input

Also add a test to lock this in:

#[test]
fn parse_rejects_empty_input() {
    assert!(KeySpec::parse("").is_none());
    assert!(KeySpec::parse("Ctrl+").is_none());
}

Downgrade gtk4-rs to 0.10 generation (glib 2.74 compatible) so CI
runs on rust:1-bookworm per org convention. Remove backend dep from
frontend crate to enforce the inter-crate boundary.

  vte4 0.9, sourceview5 0.10
