Execution plan for folding the runtime into the compiler: single
pasbuild compile -m blaise-compiler, no separate runtime module, no
make install, no ar-built blaise_rtl.a.
Records the constraining facts (programs emit RTL calls as undefined externals
satisfied by the archive; the archive is a Blaise-only ar artifact pasbuild
does not produce; RTL is now pure Pascal), the chosen target shape (RTL units
relocated into the compiler source tree, compiler produces a cached rtl/*.o dir
the internal linker consumes), and the full blast radius — project.xml,
uToolchain/FindRTLArchive, native driver AddArchive, all four fixpoint scripts,
rolling-bootstrap, CI bootstrap.yml, ~12 tests, release artifacts, and docs.
Recommends DOTTED-FLAT unit names (runtime.atomic, runtime.str, …) over a
subdirectory: the unit loader is filename-based (dotted name -> dotted file, no
subdir traversal), so dotted-flat keeps the units on the compiler's existing
unit-path with zero new path entry, at the cost of a one-time uses-clause
rename sweep; emitted runtime symbols are unchanged either way.
Sequences the migration archive-compatible-first (old release keeps cold-
bootstrapping) and only drops the archive once a stage-2 binary produces/
consumes the .o cache, with a full four-fixpoint + cold-bootstrap re-verify
after each stage and a build-time measurement gate before keeping the
compile-per-target follow-up.
