Windows shipped a PAIR: a small permanent launcher (codebase-memory-mcp.exe)
plus the real product binary (codebase-memory-mcp.payload.exe). The launcher
existed for exactly one reason — a running .exe cannot replace its own image
on Windows, so an in-process self-update needs a second resident binary to do
the swap.
That stub is statically indistinguishable from a dropper: a small, unsigned,
zero-prevalence PE whose whole job is verify-and-execute another binary.
Defender's ML scored it Trojan:Win32/Wacatac.B!ml and blocked the v0.9.1-rc.1
release at the VirusTotal gate. It is not fixable in our code on x64 —
bcrypt-free, stripped, VERSIONINFO'd, minimal-resource and even
resource-FREE builds on CI's own MSYS2 CLANG64 toolchain were all flagged,
while the product binary scans clean on every platform.
So remove the stub and move self-update OUT of the process into install.ps1,
which runs while cbm is NOT running: Windows' image lock only blocks a
process from replacing ITSELF. now prints the exact PowerShell
command (with the Unblock-File hint for Mark-of-the-Web); install.ps1 is
idempotent, so re-running it IS the update — it stops the daemon, renames the
running binary aside (the one mutation Windows permits on a running image),
publishes the new one, and sweeps retired copies.
Windows now matches Linux and macOS: ONE binary per platform.
* packaging, install.ps1, npm and PyPI wrappers all carry a single binary
* the launcher/payload ABI contract and ~2500 lines of stub state machinery
are deleted
* every daemon start, CLI call and hook fire loses a process spawn, a named
pipe handshake and an stdio relay
* test_windows_bundle_contract.sh is rewritten as an INVERTED contract: it
now asserts no shipped surface can reintroduce a launcher/payload pair,
and that install.ps1 retires the running binary before publishing
Verified: VirusTotal 0/67 on the packaged binary and 0/58 on install.ps1 (no
certificate involved); macOS and Linux full suites green; Windows guards all
green including the new update-handoff contract; npm 10/10; PyPI 3/3.

git-apply of the staged unification recorded the new canonical entries
as 100644; workflows execute them directly (run: scripts/ci/...), so a
fresh CI checkout would fail at ci-ok/shard-union/soak/package steps
with permission denied — the same class the parity worktree's own
preflight just tripped over locally.

Closes the closable local-vs-remote venue gaps so that, outside arch
legs / YAML glue / release plumbing, every local red is a remote red
and vice versa on shared legs:
- scripts/package-release.sh: THE canonical archive step (names +
five-file Windows bundle layout defined once); _build.yml's eight
inline archive blocks become calls to it.
- scripts/ci/smoke-artifact.sh: the artifact-flow smoke lane — build,
package, extract, then the canonical wrapper in artifact mode; wired
as run.sh smoke-artifact (compose service), win.sh smoke-artifact,
and directly runnable on macOS. Archive-layout bugs now surface
locally instead of in a release dry run.
- glibc-floor leg (Dockerfile.glibc22 + compose + run.sh): portable
binary smokes on ubuntu-22.04/glibc 2.35; the dynamic binary must
refuse there (2.38+ floor by design).
- Defender-ON parity (user directive): scripts/ci/ensure-defender.ps1
enables + VERIFIES real-time protection, fail-closed; runs in every
Windows CI job (_test x2, _soak x3, _smoke, pr.yml) AND in the VM
preflight; _smoke.yml's scan engine-failure soft-skip becomes a red
gate. Expected cost: slower Windows jobs (AV scanning during
install/build/test I/O); the next dry run proves the runner side.
- Contracts: launcher-bundle five-file check retargeted onto
package-release.sh + per-archive canonical-call association;
venue-parity contract requires the new lanes, counts one
ensure-defender step per Windows job, adds --help probes for the new
entries. Extended contract fails on the pre-change tree (verified:
20 violations on HEAD).
- VM README: ephemerality/Defender posture documented — utmctl has no
snapshot verb, so per-run revert stays a manual qcow2 option; the
sweep preflight remains the standing mechanism.
