Adapted from Maitreya

Source-verse content marked with via: Maitreya in the entry frontmatter is adapted from the Maitreya Vedic-astrology software project, authored by Martin Pettau, available at saravali.de and github.com/martin-pe/maitreya8.

Maitreya is licensed under the GNU GPL v2.0 or later. The COPYING file in the Maitreya distribution states: "The software is Open Source and free for private and commercial use."

The classical verses themselves are public-domain Sanskrit scripture; the specific English renderings in Maitreya's data files reflect work by Pettau and the Maitreya contributor community.

How adaptation works in this repository

Each entry that draws on Maitreya keeps the original source verse verbatim in a ## Source verse body section, with the verse marked as adapted from Maitreya. A second body section, ## Rendering, holds Dr. Vinay Kumar Chaganti's own rephrasing of the verse in the researcher's voice — written by hand against the source. The rendering is the layer published to the chart UX; the source verse is retained as the canonical reference and is available on the chart as an "Original source" expandable.

Where the rephrasing has not yet been authored, the chart UX falls back to displaying the source verse with attribution. The two-track structure is a deliberate compromise between license respect and editorial control: the source verse is preserved as-is to honour Maitreya's contribution; the rendering layer is original work.
