Code

// Test 430_001: Cross-Module Override (No Delegation)
// Override coordinator with immediate error - completely replaces the default.
// No call to .default, so the default pipeline never runs.
//
// This proves cross-module overrides work without delegation.

~import std/compiler

// Override coordinate - just return error immediately
// Cross-module subflow override: the colon in the path makes it an impl.
~std/compiler:coordinate => error "Testing!"

if grep -q "User-controlled pipeline: 3 passes" backend.err; then
    echo "✓ Custom coordinator metrics found in backend.err"
    exit 0
else
    echo "✗ Custom coordinator metrics NOT found - default coordinator may have run instead!"
