; test-tool-reasoning.scm - Test Layer 8: Inference rule discovery and verification
;
; Tests that the system genuinely "understands" grep:
; Test 1: Rule discovery - did discover-all-rules! produce ImplicationLinks?
; Test 2: Preconditions - grep has preconditions "pattern" and "directory"
; Test 3: Postconditions - grep has postcondition "lines"
; Test 4: Chaining - grep chains to something (output PMI-matches another tool's input)
; Test 5: Applicability - grep is applicable for at least one vague word
; Test 6: Verification - verify-all-rules returns 0 failures
; Test 7: Layer 8 - inference layer emerged
;
; Run: guile test-tool-reasoning.scm test
