Move the Dockerfile.rust runtime stage from debian:bookworm-slim to distroless gcr.io/distroless/cc-debian12:debug to shrink the OS attack surface flagged by Docker Scout (37 base-image CVEs in ruvnet#1140). All 37 CVEs are real but unreachable — the container runs a single Rust binary with no Perl/Python/compiler, the 1 Critical + 2 High are all in perl modules not installed in the slim base, and none have a Debian 12 fix (so re-pulling slim clears nothing). Distroless cc-debian12 ships only glibc + libgcc/libstdc++ + libssl + the CA bundle and drops perl, apt, tar, gnupg, pam, shadow, systemd libs at the source. - Use :debug variant: entrypoint is a /bin/sh script with real security logic (ruvnet#864 fail-closed auth + routing); invoke it via /busybox/sh. - Move the ruvnet#520/ruvnet#514 UI-asset + binary regression check into the builder stage (the distroless runtime has no shell to RUN it in). Not yet built/verified in this env — needs a real docker build of docker/Dockerfile.rust + on-hardware (COM7) verification per the release process before publishing.

Summary
Moves the
ruvnet/wifi-densepose:latestruntime stage (docker/Dockerfile.rust) fromdebian:bookworm-slimto distrolessgcr.io/distroless/cc-debian12:debug, shrinking the OS attack surface flagged by Docker Scout in #1140.Closes #1140.
Background (analysis of #1140)
The report listed 37 base-image CVEs (1 Critical / 2 High / 4 Medium / 28 Low / 2 unspecified). All are real, but none is reachable in this image:
perl, and 6 of the 8 perl CVEs (including both Highs —IO::Compress/IO::Uncompress/HTTP::Tiny) reference modules that aren't even installed in the slim base.CVE-2026-12087, Socket out-of-bounds read, AV:N) needs a running Perl program calling the affected function — there is none.debian:12-slimwould clear nothing.The fix removes the packages at the source by switching to distroless, which ships only glibc + libgcc/libstdc++ + libssl + the CA bundle.
Changes
docker/Dockerfile.rust: runtime base →gcr.io/distroless/cc-debian12:debug.:debugvariant chosen because the entrypoint is a/bin/shscript carrying real security logic (Docker default exposes unauthenticated sensing API and /ws/sensing stream #864 fail-closed auth +cog-ha-matter/homecorerouting); it bundles a static busybox shell at/busybox/sh, through which the entrypoint is now invoked explicitly.RUNit in).CHANGELOG.md: entry under[Unreleased] > Security.Verification (MEASURED — linux/arm64, Docker 29.5.3)
docker build -f docker/Dockerfile.rust0.0.0.0+ no token →exit 64GET /ui/index.html,GET /GET /api/v1/sensing/latest(CSI_SOURCE=simulated)Package surface: runtime tracked dpkg set drops to 10 packages —
base-files, gcc-12-base, libc6, libgcc-s1, libgomp1, libssl3, libstdc++6, media-types, netbase, tzdata.perl/apt/tar/gnupg/pam/shadow/systemd/util-linux/coreutilsare all absent.Net against the reported 37: the 1 Critical + 2 High + all 4 Medium are eliminated, plus ~21 of the 28 Lows. Remaining residuals are the irreducible glibc/openssl/gcc-base baseline Lows present in any glibc-based image.
The base-image swap does not touch CSI ingestion, so on-hardware (ESP32) sensing behaviour is unchanged from the prior image.
