JOURNAL — sub-phase rcust (Builder)

2026-06-10 bootstrap

Read phase plan (recipe-custom-restructure-full-plan.md), plan.md §6.1/§7/§9, and the reference spec docs/recipe-customization.md @ 76a4b6b in full. Created phase state files. Work branch will be restructure/recipe-custom off main @ 76a4b6b. Starting P1: reading the six current loaders (run_recipe_ci.py::_load_meta, conftest.py::_recipe_meta, lifecycle.py::_recipe_extra_env, lifecycle.py::_recipe_meta_flag, deps.py::declared_deps, canonical.py::is_canonical_enrolled) before writing harness/meta.py.
