win32-ix86 verification kits repointed at minimal payloads punk8min.vfs / punk9min.vfs

The full punk8win/punk9win_for_tkruntime payloads shipped x64-only binary
packages into the 32-bit kits (user-observed): a higher-versioned x64 Thread
2.8.12 shadowed the LUCK runtime's working 32-bit 2.8.5 on plain package
require and broke the repl (tsv machinery), and x64-only dlls (tcludp etc)
failed with "couldn't load from current filesystem". Measured: forcing
-exact Thread 2.8.5 loaded fine, proving the backport's zipfs dll loading
works and the failure was purely wrong-arch version shadowing.

New minimal payloads: both startup fauxlinks (root main.tcl + the undroidwish
app/main.tcl hook) plus directory fauxlinks to MULTI-ARCH packages only -
those carrying a win32-ix86 platform subdir: iocp-2.0.2 (both majors, from
punk8win.vfs / punk9magicsplat.vfs) and twapi-5.0b1 (tcl8, from punk86.vfs).
No binary duplication in VCS (G-004); the pure-tcl module/lib set arrives via
the dll-free _vfscommon.vfs overlay.

Verified: both kits boot, resolve punk::args from _vfscommon, load Thread
(2.8.5 own-arch on LUCK / 3.0.5 static on sfe), iocp 2.0.2 (ix86 dll), twapi
(4.7.2 stable beats the linked 5.0b1 beta under prefer-stable on LUCK; 5.2.0
static on sfe), udp 1.0.11 on LUCK (own archive copy, no longer shadowed);
piped shell sessions evaluate cleanly on both with zero tsv-unavailable
noise. Remaining specimen quirk (out of payload scope): punkluck86 segfaults
at process exit AFTER a completed shell session (exit 139) - repl-teardown x
2019-era runtime interaction; the tclsh subcommand exits 0 with all four
packages loaded. punkexe subtree 69 tests 0 fail.

 - `src` mode loads unbuilt modules and libraries from the project's `src/` tree (`src/modules`, `src/lib`, `src/bootsupport`, `src/vendormodules`) instead of built output. It also runs an inline `#modpod` package-ifneeded scanner (using Tcl builtins only, since no punk modules are loaded at boot time) and sets `package prefer latest` so `999999.0a1.0` dev modules are preferred over stable bootsupport/vendored copies.
 - `_config/punk_main.tcl` and `_config/project_main.tcl` derive the kit's payload location from the runtime's own zipfs mount table (G-129): zipfs presence keys on `tcl::zipfs::mount` (not `tcl::zipfs::root`, which the androwish/undroidwish 8.6 backport lacks), the mount base is the table entry whose archive file is `[info nameofexecutable]` (fallback: the mount containing the boot script), `//zipfs:/app` stays the expected modern answer rather than a compiled-in assumption, and a mounted archive that cannot be attributed to the executable is reported on stderr. The derivation lives in `::punkboot` procs (`zipfs_kit_mountbase`, `zipfs_mount_pairs`, `path_within`) that remain defined after boot for probing and tests. Both files carry identical copies of this logic (G-031 is the planned consolidation). Characterization: `src/tests/shell/testsuites/punkexe/kitmountpoint.test`.
 - `punk8win.vfs` carries TWO startup-script fauxlinks resolving to `_config/punk_main.tcl`: root `main.tcl` (modern zipfs and metakit convention) and `app/main.tcl` (the undroidwish family sources `app/main.tcl` INSIDE the attached archive; the file is inert in kits whose runtime does not look for it). Fauxlink targets are link-location-relative (symlink semantics): `make.tcl`'s `merge_over` resolves them against the link file's own directory, which is indistinguishable from the old vfs-root-relative resolution for root-level links.
+- `punk8min.vfs` / `punk9min.vfs` are MINIMAL payloads for the win32-ix86 verification kits (punkluck86 / punk91ix86 in `src/runtime/mapvfs.config`): both startup fauxlinks plus directory fauxlinks to MULTI-ARCH binary packages only - packages whose own tree carries a `win32-ix86` platform subdir (iocp-2.0.2 for both majors, twapi-5.0b1 for tcl8), linked from their existing homes in sibling `.vfs` folders so no binary is duplicated in VCS. Everything pure-tcl arrives via the `_vfscommon.vfs` overlay (which deliberately contains no dlls). Composition rule: an x64-only binary package must NOT be added to these payloads - a higher-versioned wrong-arch copy silently shadows a runtime's own working 32-bit package on plain `package require` (measured 2026-07-27: payload Thread 2.8.12 x64 beat the LUCK runtime's 2.8.5 and broke the repl), and wrong-arch-only packages surface as "couldn't load from current filesystem" at require time.
 - `dev` mode loads built output from `<projectroot>/modules` and `<projectroot>/lib`; `src` mode loads unbuilt source from `<projectroot>/src/modules` etc. Use `src-dev-internal` to combine both with src priority.
