"""Credential lifter — credential-capture / reuse technique tagger.

Contract step E.1.6 of ``development/TTP_TAGGING.md``. Empty body.
Implementation phase reads ``Credential`` and ``CredentialReuse`` rows
populated by the reuse-correlator and emits Credential-Access /
Lateral-Movement techniques. Tolerates absence of the reuse-correlator
output by inheriting :class:`TolerantTagger` — the correlator is a
sibling worker, not a hard dependency.
