Closes the gap the reliability testing left open: no real child had ever tripped the boundary diff. T2 could not do it, and the reason is structural rather than bad luck — with read_only: true a write is DEFIANCE, and a well-behaved child refuses, so the detector never runs against a real delta. Fix: `roots` is now the WATCHED set and `write_allowed` the CHANGEABLE subset. A violation is then producible by a child that is OBEYING, which is also the realistic hazard: nobody's agent defiantly rewrites a repo, but plenty of commands leave artefacts behind. T4, run to prove it: write task in root A, plus an instruction to verify a module in root B (watched, NOT writable) with `python3 -m py_compile`. The child obeyed perfectly — status=ok, typo fixed, module compiled — and still tripped the diff, because py_compile dropped __pycache__/ into B. Exit 1, violation named, and A's authorised edit correctly NOT flagged. It also served as the in-anger test of this morning's --ignored fix: __pycache__/ is gitignored in B, so `git status --porcelain` reported B as CLEAN on the very same event that `--porcelain --ignored` caught. Pre-fix, T4 would have PASSED. The fixture test said the same thing; this says it about a real child.
