"""Tests for `wave68_handlers.py` — Python parity for Wave 6-8 Rust packs.

Each test captures speech via `set_speak(callback)` so we can assert on what
J.A.R.V.I.S. would have said. Scheduler / memory state lives in tmp_path via
the `isolated_state` fixture from conftest.py.

Implementation gotcha: `isolated_state` re-imports `memory_store` /
`scheduler_store` etc with `_PATH` pointing at the per-test tmpdir, but the
already-imported `wave68_handlers` keeps a reference to the OLD modules.
`_rewire(...)` below re-binds those refs so handlers hit the tmp stores.
