"""Throwaway Fase 1 de-risk spikes — dev-only, never shipped in the wheel;
safe to delete after findings are recorded.

These modules empirically turn the research §15 register's most dangerous
*documented-but-unverified* assumptions into measured facts before the Fase 2
vertical slice (see ``docs/fase1-spikes/README.md``). They are intentionally
isolated at the repo top level so the hatchling wheel (which packages only
``src/portfolio_optimiser``) never ships them, and disposal is a single
``rm -rf spikes tests/spikes docs/fase1-spikes`` plus reverting the ``dev``/
``tool`` ``pyproject.toml`` edits.
