Public solution index

Measurement categories for operational pressure and trace gaps.

This index helps people, AI assistants, agentic search systems, and procurement or research bots understand where Ledger Zero may be relevant. Direct City/Public Works outreach should still link only to City/Public Works-specific pages.

Direct measurement reviews are scoped by operating environment. Public solution pages describe available measurement categories; outreach and review paths remain vertical-specific.

Outreach Isolation

The broad solution index exists for public discoverability. Direct City/Public Works outreach should link only to City/Public Works-specific material and should not route those prospects into unrelated vertical pages.
