025 auto discharge disabled

✓ Passing This code compiles and runs correctly.

Code

// TEST: Auto-discharge disabled via --auto-discharge=disable flag
//
// When auto-discharge is disabled, the phantom semantic checker should
// report KORU030 for unsatisfied cleanup obligations.
//
// This test verifies that:
// 1. The --auto-discharge=disable flag works
// 2. The phantom checker correctly catches obligations when not auto-discharged
//
// Expected: KORU030 error for unsatisfied obligation

~import "$app/fs"

// Open a file but don't close it
// Without auto-discharge, this should error
~app.fs:open(path: "test.txt")

Expected Error Pattern

error[KORU030]: Resource

Actual Compiler Output ✓ Pattern matched

error[KORU030]: Resource '_' [opened!] was not discharged. Call: app.fs:close
  --> phantom_semantic_check:17:0
