Development record

README.md:40 introduces the principles with a link to the record site's foundations page ('abcd is founded on several [principles](https://abcdev.app/record/foundations/), ...'). README.md:47, :57 and :60 then name three principles that page cannot carry: '**abcd builds abcd**', '**Work starts from an intent**' and '**The record is part of the product**'. The foundations page is built from the principle store alone (internal/core/site/foundations.go:16-18, explorer.go:721-746). .abcd/development/principles/ has no record for any of the three, and git grep finds those names only in README.md. The other five are in the store: prefer-the-experiment-to-the-inference.md, verifier-selects-gates-decide.md, less-but-better.md, the-record-lands-with-the-act.md and enforcement-claims-are-facts.md. So a reader who follows the link finds five of the eight principles the README names.
