obligation lost at boundary

✓ Passing This code compiles and runs correctly.

Code

~import "$app/bad_subflow"
~app.bad_subflow:bad_subflow()
input.kz

Error Verification

Expected Error Pattern

This test must fail because bad_subflow opens a file with cleanup obligation
but returns without documenting the obligation in its return signature.
The obligation is lost at the flow boundary.

Actual Compiler Output

🎯 Compiler coordination: Passes: 13 (flow-based: frontend, analysis, emission)
Error: output_emitted.zig:32:28: error: use of undeclared identifier '__inline_flow_1'
                    return __inline_flow_1(.{  });
                           ^~~~~~~~~~~~~~~

Imported Files

~import "$app/fs"

// BAD: Opens file but doesn't document obligation in signature
~pub event bad_subflow {}

~proc bad_subflow {
    ~app.fs:open(path: "data.txt")
    | opened f |> done {}
    // ERROR: f.file has [opened!] obligation
    // but 'done' branch has no [!] in signature
    // Obligation is lost!
}

const std = @import("std");
const File = struct { handle: i32 };

~pub event open { path: []const u8 }

~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 };
