# Phase 5.10 Task 8: NaiveProxy client for partner-edge UC5 channel.
# Builds from klzgrad/naiveproxy upstream releases (signed tarballs).
#
# Multi-stage: fetcher pulls + verifies binary, runtime is distroless cc.
# Image target ~30MB (naive binary ~10MB + distroless base).
#
# NAIVE_VERSION: v148.0.7778.96-5 (latest stable as of 2026-05-18).
# Release page: https://github.com/klzgrad/naiveproxy/releases

# Note: don't run `/opt/naive/naive --version` here — naive is a glibc binary
# but the alpine fetcher stage has musl, so the dynamic linker mismatch causes
# `not found` exit 127 even when the binary is correctly placed. The final
# distroless cc-debian12 stage is glibc, so the binary executes there.
# Runtime smoke validation happens via partner-edge healthcheck.
