A mispointed mock.patch does not always fail loudly. In code_tutor it
spins, because the code under test reads from an input callable in a
retry loop. Documents running under timeout, asserting patch targets
resolve first, the absolute-patch-string cost, and the silent no-op sed.

mock.patch pins a name to the module it is patched on. A function that moves
resolves collaborators through its new module's globals, so the patch stops
reaching it -- the failure is either AttributeError or, worse, a real call to
what should have been mocked. This governs brother_printer (15 files, ~90
patched names) and probably code_tutor. The grep to run first is in the doc.
Also records the user's decision: editing tests to follow moved code is
allowed, bounded by no assertion changed, nothing deleted or weakened, and an
identical pass count. The alternative was ~8 delegate stubs per file.

The handoff had grown to 264 lines -- a violation of the very cap it exists to
enforce. The Python recipes move to docs/python-split-recipes.md; the handoff
keeps a pointer.
Also refreshed what had gone stale: the directory distribution said python_pkg
50 and '48 near-misses' from before this session's 9 splits. A future session
reading a stale count would not know which other claims in the file to trust,
so the numbers are now explicitly labelled a snapshot with the script as the
authority, and the per-package breakdown points at brother_printer (15) and
code_tutor (13) as where the bulk now sits.
Corrected the test recipe too: shared builders go in tests/conftest.py, not a
_helpers.py -- name-tests-test rejects the latter, which the earlier wording
would have walked the next session straight into.
