Follow-on goals from the G-122 host/target split, each drafted with its overlap survey
and approved before writing. The G-057 contract edit (title, Scope, Goal, Acceptance) was
shown clause-by-clause and approved per the proposal-first rule.
G-057 amended - the goal was drafted before G-122 separated host from target, so its skip
condition read as one host-shaped test ("non-Windows platform skips") while its Notes used
target language. Split in two: a target with no PE resources is NOT APPLICABLE, a windows
target on a host that cannot run twapi is a distinct shortcoming. Both still emit a text
sidecar, now produced for every kit on every target and defined so the parked RT_VERSION
follow-on extends the same file rather than adding a second. Embedding sits behind a
single mechanism seam, and the twapi arm is explicitly PERMANENT - the seam selects
between mechanisms, it does not replace one: twapi is vendored and git-tracked
(src/vendorlib_tcl8|9/win32-x86_64/twapi-5.0b1) and reachable from make.tcl's auto_path,
so a fresh windows checkout that fetches a runtime and bakes gets icons with no build
toolchain (probed under a stock tclsh 9.0.3 and a fetched plain family runtime). The
per-vfs override is settled as shared across a kit definition's targets with no target
dimension.
G-127 - cross-target bake of a custom .vfs. G-122 made the build READ the right runtime
for a target; this makes it WRITE the right kit for one. Three measured gaps: output is
flat, so two POSIX targets of one kit collide (within a run the duplicate guard renames by
RUNTIME not platform; across selective runs exe_names_seen resets and the second
overwrites the first); the payload model is one hand-curated folder per target
(punk9linux.vfs, not a vfslibs participant, with vendorlib_vfs.toml hardcoding the
platform into its source path - a shape inherited from G-037 when there was one target);
and nothing verifies payload against target. Non-native kits go to bin/kits/<platform>/
with native staying at bin/<name>; /bin/* already ignores it so no dual-track ignore work.
Records that G-114 and G-115 overlap yet never reference each other - the platform axis
and the payload axis have never been connected.
G-128 - portable PE resource stamping via a vendored zig tool, plugging into G-057's seam
without retiring its twapi arm. Feasibility measured: zig rc (resinator, bundled in the
0.16 toolchain) is a resource COMPILER supplying the RT_GROUP_ICON/RT_ICON structure
reference, not a patcher - we never link these runtimes, so patching an existing PE is the
work. In our runtimes .rsrc is not the last section (.reloc follows), so the
implementation appends a section and repoints the resource data directory, which shifts
the overlay: safe for an archive-relative zip, not for a file-relative one, so the unsafe
case is refused rather than corrupted. The payoff beyond portability is post-hoc stamping
of a finished kit, which removes G-057's icon-before-append ordering constraint. Its
distribution is settled as buildable from vendored source AND publishable as a punkbin
artifact, so the no-toolchain route need not depend on the committed twapi (the G-004
tension).
Also adds non-contract Related back-pointers in G-057 to G-122/G-127/G-128.
