Why treat these three essays as one investment system?

The P4.2 investment thesis fails if any single lens is applied in isolation. Battery chemistry economics determines equipment margin but says nothing about revenue stack. Hall-BESS revenue analysis prices dispatch but says nothing about which architectures are permissible to procure. Regulatory analysis determines what gets procured but says nothing about who captures margin within the procured stack. The three interlock as P4.2 value = physical economics × monetisation rights × regulatory / site eligibility.

How does the P4.2 investment stack relate to the Grid-to-Chip framework?

P4.2 is one sub-block within P4 (Hall Power), which is one of five stages in the Grid-to-Chip framework. The trilogy demonstrates a pattern that applies at other stages: multiple investment lenses on a single architectural block.
