# verify-bundle-compatibility.sh -- Verify ALL bundles share a consistent
# constrained-package closure when installed together
#
# Usage: verify-bundle-compatibility.sh <arch> <bundlesDir>
#
#   arch       - amd64-gpu or arm64-cpu
#   bundlesDir - directory containing <bundleId>-<arch>.tar.gz for every bundle
#                in feature-manifest.json's "bundles" map
#
# Runs with --entrypoint bash (no entrypoint bootstrap), so uses /opt/venv
# directly, matching build-bundle.sh's own base assumption.
#
# Why this exists: verify-bundle.sh (this directory) verifies each bundle in
# ISOLATION -- a fresh /opt/venv per bundle. That can never catch a conflict
# that only appears when two bundles are installed into the SAME shared venv,
# which is exactly how real users install them (BullMQ /data/ai/venv is one
# shared venv for every installed bundle, not one venv per bundle). That gap is
# exactly how the scipy ABI strand (see docs/QA_REPORT_v2.0.0_release_2026-07-07.md
# BUG-2, and the earlier incident in project memory project_ai_bundle_numpy_abi_strand)
# shipped twice: each bundle passed verify-bundle.sh alone, and the manifest's
# `constraints` pin was correctly applied at each bundle's OWN build time, but
# nothing ever checked that bundles built at DIFFERENT times agree with each
# other once layered into one venv.
#
# This script installs every bundle for the given arch into ONE fresh venv, in
# manifest order, then asserts that every constrained package (per the
# manifest's top-level "constraints" array) has EXACTLY ONE version present,
# and that it matches the constraint exactly. Run this before publishing any
# bundle rebuild, for every arch, on any subset of bundles you touched AND the
# full set (a rebuild of bundle A can still leave bundle B stale).
#
# Exit codes: 0=pass, 1=integrity, 2=constraint violation
