Adding a data member to a class in a module interface did not rebuild every
object compiled against the old layout. The build succeeded with no error or
warning and the resulting binary mixed both layouts, surfacing later as a
SIGSEGV in a destructor.
GetInterfacesAndImplementations scans a TU's `import X;` statements when the
source is declared. An import that matches neither a module in the
Configuration nor one reachable through `dependencies` was dropped on the
floor, leaving that TU with no staleness edge to the interface it consumes.
`dependencies` is frequently assigned *after* the scan — AddTest does exactly
that, resolving tests/<name>/main.cpp and only then returning a builder whose
.Dependencies() supplies the library — so consumers of a dependency's modules
routinely carried no edge at all. A layout change then rebuilt the library,
relinked the consumer, and kept the consumer's object as it was.
Unresolved names are now remembered on the partition/implementation as
pendingImports, and Configuration::ResolvePendingImports retries them against
the dependency DAG as it stands. Build() calls it immediately before comparing
mtimes, which closes the window for every caller rather than only the ones that
declare in the right order; TestBuilder::Dependencies also calls it so the
Configuration is coherent for anyone inspecting it before the build.

The browser wasm pipeline hardcoded -msimd128 for every wasm32 target and
baked a single wasm URL into index.html, so newer codegen features that
aren't yet baseline across engines (relaxed SIMD today; threads, future SIMD
revisions later) couldn't be adopted without dropping the browsers that lack
them.
Add a general, feature-parameterized mechanism owned entirely by
Crafter.Build:
- Configuration::wasmVariants declares N codegen variants (label, extra -m
flags, runtime probes). Build() compiles the baseline plus one
outputName.<label>.wasm per variant, recompiling the whole graph (incl.
dep libs + std PCM) with the variant's flags — relaxed-SIMD is per-TU
codegen, not a link switch. wasmVariantFlags folds into VariantId so each
variant's objects/PCMs land in their own build+bin dir.
- EnableWasiBrowserRuntime emits a variants.json manifest (label -> url +
probes), preferred-first with the baseline as the universal fallback.
- The shipped runtime.js runs inlined wasm-feature-detect probes
(relaxed-simd, simd, tail-call, bulk-memory, exception-handling, threads),
picks the first variant whose probes all pass, and falls back to the single
baked CRAFTER_WASM_URL when no manifest is present (backward compatible).
- EnableWasiRelaxedSimdVariant registers the relaxed-SIMD variant — the
motivating case (Chrome 114+/Firefox 120+ enable it by default; Safari
still flag-gates it as of mid-2026).
Verified end to end: a wasm32-wasip1 build emits both wasi-hello.wasm and
wasi-hello.relaxed-simd.wasm + variants.json; Firefox selects the
relaxed-simd variant and runs it.

With test.toml + ForTarget covering the cross-arch + Windows-on-Linux
cases, the env-var-driven transport runners are dead weight. This commit
removes them and the retired tests that exercised the env-var plumbing:
- TestRunner::Ssh / SshWin / Wsl factories and their copy/exec/cleanup
template machinery.
- TestRunner::Shell enum (Host/Sh/Cmd) and the ShellQuoteSh helper —
only Host shell quoting is needed once the remote shells are gone.
- TestRunner::copy / cleanup / remoteDir / argsShell fields.
- WindowsPathToWsl and the {remote_bundle}/{bin_win}/{bundle_wsl}
placeholder substitution in RunSingleTest's transport branch.
- ParseRunnerSpec narrowed from {local, cmd, ssh, sshwin, wsl} to
{local, cmd} — the override hatch is preserved, just simpler.
- tests/SshRunner, tests/WindowsViaSsh, tests/QemuUser: these tested
the CRAFTER_BUILD_RUNNER_<target> → runner plumbing that has been
replaced by ForTarget. The runner derivation is exercised every
time CrossArchAarch64 / Wasi / WindowsViaWine runs.
- tests/UnitLib: ssh/sshwin spec assertions become "throws on bogus
spec" assertions.

Vendors toml++ v3.4.0 as lib/toml.hpp and wires it into Crafter.Build-Test
to parse a declarative test.toml manifest (target/march/mtune/sysroot/
requires/timeout/args/defines). Test discovery now treats project.cpp and
test.toml as mutually exclusive: project.cpp stays the escape hatch for
outer-driver tests, test.toml gives downstream test authors a no-boilerplate
path.
Adds:
- TestRunner::Wine() and TestRunner::ForTarget(cfg) — runner is now derived
from cfg.target (Local for host, Wine for Windows-on-Linux, wasmtime for
WASI, qemu-<arch> with QEMU_LD_PREFIX for non-host Linux). The env-var
override CRAFTER_BUILD_RUNNER_<target> still wins as a power-user escape
hatch via FromEnv.
- Declarative preconditions: tool:<name>, file:<path>, env:<VAR> are
evaluated before the build; missing preconditions Skip without paying
the compile cost.
- Hard-fail-unless-declared: when a derived runner's tool is missing AND
the test didn't declare 'tool:<that>' in requires, the missing runner
is a Fail instead of a silent Skip. Surfaces broken cross-arch CI
config that previously hid as "skipped".
- Multi-target sweep: bare `crafter-build test` (no --target=) now
iterates every distinct test.toml-declared target plus the host, so
cross-arch tests run by default without the user needing to know which
targets exist. `--target=X` bypasses the sweep.
Test struct gains a `requires_` vector so project.cpp users can declare
preconditions too (matching what test.toml writes there).
Existing tests, factories (Ssh/SshWin/Wsl/Cmd), and CRAFTER_BUILD_RUNNER_*
machinery remain intact — this commit only adds; migration and deletion
follow in subsequent commits.

In-class inline methods on a module-exported class get the @<module>
linkage attachment, and clang does not emit their bodies into
consumers; the resulting external reference fails to resolve when a
project.dll on Windows tries to call ArgQuery::Has after consuming
ApplyStandardArgs's return value. Move the bodies to the implementation
unit and dllexport them.

WASI / wasm32 target support
- Auto-detect /usr/share/wasi-sysroot on Linux when target starts_with("wasm32")
- Skip -march/-mtune for wasm (clang rejects them)
- Apply -fno-exceptions -fno-c++-static-destructors -mllvm -wasm-enable-sjlj
-D_WASI_EMULATED_SIGNAL to wasm builds (compile + std PCM, kept in sync)
- .wasm output extension in expectedOutputFor and link command
- EnableWasiBrowserRuntime(cfg): opt-in helper that drops index.html +
runtime.js next to the .wasm; runtime.js reads window.CRAFTER_WASM_URL
set in the templated index.html so a single shim handles any output name
-r run flag in the CLI: build then exec the artifact (host targets only;
rejects libraries; auto .exe/.wasm extension handling)
CI pipeline (.forgejo/workflows/ci.yaml)
- Triggers: PR/push to master + manual dispatch
- Single arch-latest container job: install deps, bootstrap, self-rebuild,
run tests, cross-compile mingw, package both archives, upload artifacts
- Rolling 'latest' release published only on push/dispatch to master
mingw cross-compile from Linux now works end-to-end:
- ExternalDependency cache key includes target so per-target glslang builds
don't collide; CMAKE_BUILD_TYPE=Release pinned (otherwise glslang appends
'd' to lib names and breaks linking); cross-compile cmake flags
(CMAKE_SYSTEM_NAME=Windows, CMAKE_*_COMPILER_TARGET=...)
- project.cpp accepts --target=<triple>; Linux-only -Wl,--export-dynamic
and -ldl are gated; mingw glslang skips the standalone exe (its libgcc_eh
link pulls pthread which mingw doesn't link by default)
- mingw compile uses -femulated-tls so std::__once_callable etc reference
the same emutls symbols libstdc++ provides
- mingw link auto-adds -lstdc++exp -lpthread
GetCrafterBuildHome() exposed from the Platform module; LoadProject (Linux
+ Windows) now both use it instead of duplicating the resolution.
Examples reorg: hello-world, library, with-module, wasi, tests — each with
its own README. Tests reorg: per-test directory with inner/ fixture, no
shared tests/fixtures/ tree. New Wasi test verifies .wasm magic bytes.

- subprocess-isolated test runner (replaces V1 dlopen-RunTest);
Pass/Fail/Crash/Timeout/Skipped outcomes via :Test partition
- TestRunner abstraction with command templates: Local, Ssh,
SshWin (cmd.exe-shell), QemuUser, FromEnv; probe-based skip
when runner unreachable
- transitive PCM-path propagation in Build(); resolveImport
walks deps recursively; depResults cache keyed by PcmDir()
so per-target builds don't collide
- cfg.sysroot threaded through BuildStdPcm + base compile/link
command (enables aarch64 cross via Arch Linux ARM rootfs)
- lib + exe split: project.cpp defines crafterBuildLib
(LibraryStatic) + crafterBuildExe (Executable depending on
it); build.sh produces lib/libcrafter-build.a alongside
bin/crafter-build for downstream static-link consumers
- Windows DLL+launcher: CRAFTER_API macro, /EXPORT flag for
project.dll's CrafterBuildProject; Crafter::Run as the real
entry point with main.cpp as a thin wrapper
- 18 tests: HelloWorld/WithModule/Defines/CrossProjectModule/
Diamond × (Linux + sshwin:winvm), plus Incremental,
BuildError, Libraries, RunnerClassification, QemuUser,
SshRunner, WindowsViaSsh, CrossArchAarch64
- single ./bin/crafter-build test runs everything; Windows
variants skip gracefully if winvm SSH alias unreachable
