…guage-server 0.0.12 ships The 0.0.12 engine was developed as 74 incremental patches. They are regrouped into 25 topic patches (module validation memo, prerequisite DAG, dependency scan memo, compiler workers, owned payloads, preamble policy, selective completion loading, ...) whose patched tree is byte-identical to the incremental series (a2e92ba00e6666eaa5d1f975a4bd65b80537dbab, checked by applying both). Every multi-change patch lists the changes it combines; patches/HISTORY.md maps the incremental numbers older notes use. The ledger gives every patch its register rows (the filename's row first), an executable test map and a drop condition, and defines steady: the series builds on every release platform, its mapped tests pass, the Ubuntu 20.04 floor package passes its runtime controls. verify-series now runs the release ledger check, so a draft patch cannot reach a tag. linux-arm64 is built again, at the same Ubuntu 20.04 / Clang 12 floor as linux-x64 (pinned arm64 rootfs), in build-test and in the release; the Linux e2e controls run on both architectures. Raw evidence (3212 files) and the incremental patches move to the evidence-0.0.12 release archive; ci/check_tree.py refuses tracked files above 1 MiB, generated module/object files and home-directory paths. The full incremental history is kept in the archive/0.0.12-joint branch.

…ot target macro tables On x86_64-pc-windows-msvc the empty-prefix comparison differed in macros only visible from a preamble (__STDC__). Macros and keywords come from the preprocessor and language options, not from the external name lookup the selective loading changes; the test now compares every declaration result and nothing else. No non-test file changes.
The empty pattern selects no names, so it runs the ordinary external lookup, and on x86_64-pc-windows-msvc a textual TU then also lists the target's predeclared size_t and type_info and macros a preamble does not offer. That is upstream behavior the selective loading does not touch; the comparison is restricted to the header's declarations there. Every non-empty pattern keeps the full comparison.
