The parent directory was created and chowned on every run, before the script looked at whether the virtualenv exists. Where the parent is not writable that reached for sudo, which a sandboxed or no-new-privileges container refuses -- so an install that had nothing to do failed with 'The "no new privileges" flag is set'. Nothing needs preparing once the interpreter is there, so the check moves ahead of the preparation and returns. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# 🐍 Virtualenv bootstrap & setup
|
|
#
|
|
# This script is responsible for creating the Python virtualenv
|
|
# used by the entire Infinito.Nexus toolchain.
|
|
#
|
|
# Important design rule:
|
|
# ❗ The venv Python interpreter CANNOT be used before the venv exists.
|
|
# ❗ Therefore we must bootstrap using system python3 first.
|
|
#
|
|
# Lifecycle:
|
|
# 1) Use system python3 to create the venv
|
|
# 2) Afterwards, Makefile provides PYTHON=${VENV}/bin/python
|
|
# 3) All tooling runs inside the venv from then on
|
|
#
|
|
# This avoids chicken-and-egg failures in CI and on fresh machines.
