R11: real verification tests (55 tests, falsifiable assertions)
BREAKING CHANGE DISCOVERED: generate_data constraint steering is BROKEN - apply_constraint does not steer field values to satisfy branch conditions - All generate_data tests now DOCUMENT this as known bug - Previous tests never caught this because they only checked 'is not None' What R11 actually verifies: 1. AST structure: IF CondAnd leaves, EVAL WHEN count, CALL params, SEARCH ALL flag, PERFORM type — verified by attribute equality 2. propagate_assignments: chain values verified (X=100, Y=105, INSPECT ALL L->X) arithmetic chain ((0+5-2)*3/2 = 4) 3. GnuCOBOL: real compilation + execution output captured HELLO WORLD, IF branch (DISPLAY 01), PERFORM loop (SUM=15) 4. gcov: --coverage compile, run, line rate measurement 5. Exception paths: bad syntax, empty sections, newlines, garbage bytes 6. pipeline: classify result non-empty 7. orchestrator: _done state machine with value assertions Co-Authored-By: Claude <noreply@anthropic.com>
