Allow snapshots to share a cooperative cancellation token without cancelling independent operations or blocking input admission.
Discover and load project sources with authoritative editor overlays, shared Prim ownership, and cancellable discovery process groups. Preparation installs inputs without requiring semantic analysis to succeed. Expose lifecycle application and query access, reuse source and foreign loading, and update the existing LSP's Prim ownership for compatibility. Workspace command-sequence coverage follows with the service. Amp-Thread-ID: https://ampcode.com/threads/T-01a09f13-27ee-7254-b6ee-b0b55fbf6944 Co-authored-by: Amp <amp@ampcode.com>
Own open documents, compilation generations, readiness, request cancellation, diagnostics, and stale-result validation behind typed workspace commands. Keep desired lifecycle separate from worker occupancy so rebuilds preserve buffers while retiring obsolete work. Exercise the public API with deterministic command sequences covering readiness races, rebuild failures, authority, diagnostics, completion identities, overload, and discovery cleanup.

Explain the workspace's high-level ownership and publication contracts. Demonstrate lifecycle and cancellation, diagnostics through document edits and saves, and completion resolution and rename handling without embedding a transport in the service.

Summary
Verification
Confidence 4/5 - Strong coverage, with platform validation outstandingThe lifecycle, stale-result, cancellation, diagnostics, document, failure-recovery, and shutdown paths have dedicated tests. Confidence is reduced because Windows runtime behaviour was not verified and cancellation is cooperative. WalkthroughChangesWorkspace analysis service

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Handle ConnectionReset when the source process group is reaped.
SourceCommand::drop kills and waits for the GroupChild in compiler-bin/iris-build/src/analysis.rs. Windows can report this peer termination as ConnectionReset instead of EOF. The current unwrap() then panics. The windows-latest job runs these tests with cargo nextest run.
Keep the no-output check. Tokio's read_to_end retains bytes read before a later error, so remainder.is_empty() also rejects partial output on the reset path.
🐛 Proposed fix for the Windows reset
let mut remainder = vec![];
- assert_eq!(bounded(reader.read_to_end(&mut remainder)).await.unwrap(), 0);
+ match bounded(reader.read_to_end(&mut remainder)).await {
+ Ok(read) => assert_eq!(read, 0),
+ // Windows reports a reset instead of a clean EOF when the peer process is terminated.
+ Err(error) if error.kind() == std::io::ErrorKind::ConnectionReset => {}
+ Err(error) => panic!("unexpected socket error: {error}"),
+ }
+ assert!(remainder.is_empty());📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Purpose
Introduce
iris-workspaceas an independently testable service for the language-server redesign. It owns workspace readiness, compiler generations, open-document authority, rebuilds, cancellation, diagnostics, and typed analyzer requests. The existing language server is not migrated in this PR.Design
iris-build, reusing source loading and adding cancellable discovery process groups and shared Prim ownership.The four commits separate query cancellation, build preparation, the workspace service with command-sequence tests, and a single runnable language-server walkthrough.
Verification
cargo check -p building -p iris-build -p iris-workspace -p iris-lsp -p iris-cli --tests --examplescargo nextest run -p building -p iris-workspace: 75 tests passed.just t lsp: all tests passed, no pending snapshots.cargo run -p iris-workspace --example language_server: all scenarios passed.git diff --checkpassed.Discovery process cleanup was exercised on Linux; Windows runtime behavior was not verified. Cancellation remains cooperative and does not interrupt an already-running query or release its snapshot locks immediately.
