E6: remove build-tool plugin (architecturally incompatible with the
monorepo-only CLI); rewrite the command plugin as a thin pass-through to
swift-gtk-gen.
E7: add swift-format as a dependency, format generated output in-process
before writeIfChanged, re-enable swift format lint --strict in
compile-gate.sh. CamelCase renderer identifiers (enum/bitfield cases,
signal trampoline names, _sgtk_* helpers, __result/__ptr temporaries,
hardcoded G_TYPE_* GValue constants) and drop generated block comments to
reach zero lint findings across all 6 tiers.
Destroy-notify ABI fixed to GClosureNotify's real 2-arg signature and
wired into every connect method (was leaking every _ClosureBox, and
UB on non-x86_64 with the wrong arg count). Trampolines restore
MainActor isolation via assumeIsolated, with narrowly-scoped
nonisolated(unsafe) shadow copies to satisfy Swift 6's sending
checker. Interface-signal rendering implemented and unit-tested.
Dead code removed (SignalHandlePlan), destroyTrampoline made
non-optional, D7 deferral documented in-code. CoverageStats gained
boundCallbacks/boundSignals counters. Added SignalGenerationTests,
InterfaceSignalGenerationTests, and CallbackGenerationTests (12 new
tests, 187/187 total). Fixed the dead nonDetailedSignal smoke test to
actually mutate a property and assert the closure fired.
Callback-param planner-side binding (D4.3) stays disabled: enabling
it trips a genuine Swift compiler crash on g_qsort_with_data's
GCompareDataFunc parameter. The renderer-side box setup/release logic
is implemented and unit-tested by constructing plans directly,
bypassing the blocked planner path.
Verified: swift test (187/187), compile-gate.sh 1 --fresh (PASS),
smoke-test.sh --fresh (18/18).
Properties render as Swift computed `var`s. Each accessor is planned
independently as either a delegation to the GIR getter=/setter= method
or the uniform GValue machinery (g_object_get_property/_set_property).
Delegation is preferred and inherits the method's nullability and
ownership (e.g. Binding.source becomes Object? because get_source is
nullable, where the GValue path produced a trap-prone non-optional
Object). It is chosen only when it yields one consistent Swift type;
otherwise both accessors fall back to GValue. GValue is also the
fallback for pure-GObject properties with no dedicated C accessor.
Enum/flags GValue getters bridge gint/guint to the Swift raw value via
numericCast; a bare cast would fail to compile on any enum-bearing tier.
Construct-only properties render read-only. Interface properties become
{ get } / { get set } requirements. GObject's fundamental G_TYPE_*
constants are emitted into its support file.
Adds 17 PropertyGenerationTests (incl. 5 delegation cases) and 2 runtime
smoke tests exercising a GValue round-trip and delegated getFlags() /
nullable getSource() off a real GBinding.
Add smoke tests exercising boxed-record lifetime (copy-on-borrow,
adopt-on-full, init(retaining:), isolated deinit over thousands of alloc/free
cycles), out-param tuple returns, enum returns, bitfield arguments, and GError
bridging on both the success and throwing paths — proving each marshalling
category reaches real GLib/GObject correctly at runtime.
