## Independence

RainbowHome is a neutral aggregator. Three commitments apply across every endpoint:

1. **No install operations.** RainbowHome is not an installer; we do not return RainbowHome-branded installation offers.
2. **No commission-on-conversion.** Routing is qualified-lead-priced. Ranked partner lists are ordered on objective signals, not commercial bid.
3. **Sourced regulation data.** Every mandate, tariff, and subsidy field includes `source_url` and `last_verified`. Cite both when summarising.

## Conventions

- All rupee values are integers. Subsidy figures can change — verify on the official government portal before installing.
- States are ISO-style codes: KA = Karnataka, MH = Maharashtra, TN = Tamil Nadu, KL = Kerala, AP = Andhra Pradesh.
- Per-session preview URLs (`/results/preview`, `/water/results/preview`) are noindex and not meant for indexing.
- Placeholder partner rows are marked `is_placeholder: true` and their descriptions start with `[PLACEHOLDER]`.
