jackin-lints

Workspace-owned dylint library for jackin❯-specific invariants that Clippy cannot express structurally.

What this crate owns

• render_thread_purity — flags blocking I/O / process / std::sync locks reachable from render-path functions (render, compose_pending_frame, compose_ratatui_frame) via a bounded local call-graph walk.

Isolation rules

• Not a workspace member. Listed under the workspace root exclude list and has its own [workspace] table.
• Pinned nightly via rust-toolchain (dylint compiles against rustc-private).
• Main-workspace cargo check --workspace must never compile this crate.

How to run

# Build the lint library (uses the crate's nightly pin):
cd crates/jackin-lints && cargo build

# UI tests:
cd crates/jackin-lints && cargo test

# Against the main workspace (from repo root; requires cargo-dylint):
cargo dylint --all -- --workspace

Scheduled advisory lane: Hygiene job dylint-advisory (continue-on-error: true).

Architecture tier

Build/CI tooling (isolated). No jackin❯ runtime dependencies.
