Error Verification

Expected Error Pattern

Test expects KORU032 error when trying to dispose outer-scope resource inside loop body

Actual Compiler Output

error[KORU032]: Cannot dispose outer-scope resource 'f' inside @scope boundary. Handle outside the scope or escape via branch constructor.
  --> auto_discharge:4:0

❌ Compiler coordination error: Auto-discharge failed (multiple disposal options or no disposal event)
error: CompilerCoordinationFailed

Imported Files

// Library module: fs
// Defines filesystem operations with cleanup obligations

const std = @import("std");

// File type with phantom states
const File = struct {
    handle: i32,
};

// Open a file - returns opened! state (requires cleanup)
~pub event open { path: []const u8 }
| opened *File[opened!]

~proc open {
    std.debug.print("Opening file: {s}\n", .{path});
    const allocator = std.heap.page_allocator;
    const f = allocator.create(File) catch unreachable;
    f.* = File{ .handle = 42 };
    return .{ .opened = f };
}

// Close a file - CONSUMES opened! state (disposes the resource)
~pub event close { file: *File[!opened] }

~proc close {
    std.debug.print("Closing file\n", .{});
