Dendrology has been rebuilt from the ground up. The old site was hand-written HTML — every page its own file, every count typed by hand, nothing checking whether any of it stayed true. Between August 11 and 12, 2026, four planned phases replaced it with the site you’re reading now.
What the rebuild produced, in the order it landed:
- A structured archive (Phase 1): the encyclopedia reorganized into five wings — Environmental Systems, Machine Learning, Applicable Systems, Weather Model, Career Opportunities — each entry one Markdown file whose layout, navigation, search, and machine artifacts all derive from it.
- A truth standard (Phase 2): every factual claim on core pages must now be derived (computed from the site’s own data at build time), cited (backed by a live source), or honestly future-tense. Claims that fit none of those moved under the clearly-badged “What could be” vision layer. Checkers run against every build and fail it on a violation.
- Learning paths (Phase 3): two free, ungated routes through the archive — Environmental Data Scientist and Precision Agriculture Specialist — whose coverage numbers are computed from entry status at build time, never typed. Missing entries are listed as the gaps they are, and double as the writing backlog.
- An agent context layer (Phase 4): the repo now teaches its own rules to the coding agents that help build it. At that phase’s close, the link checker walked 1,626 internal references and found 0 broken, and the search index covered 73 pages.
This dispatch is itself the fifth phase arriving: a channel for build notes like this one, new-entry announcements, field notes, and spotlights — with an RSS feed, so you can follow the site’s pulse without watching its pages.
