Evaluate the architectural hallmarks that define the salient features of the Indian Constitution:
1. The structural integration of a localized third tier of governance following the 1992 constitutional amendments.
2. The absolute structural supremacy of the judiciary over the sovereign law-making power of the parliament.
3. The systemic blending of both rigid special amendment procedures and flexible simple majorities.
4. A heavy systemic reliance on unwritten historical conventions rather than detailed textual codification.
5. The enforcement of a unified, single national citizenship irrespective of state residency.
