Problem

On a fresh checkout (no secrets/*.env), make test fails at setup_secrets with Error 141.

randstr() pipes tr into head -c N. Once head has enough bytes it closes the pipe and tr is killed by SIGPIPE (exit 141). The script runs with set -euo pipefail, so the pipeline status aborts it.

Fix

Append || true to the pipeline in randstr() so the expected SIGPIPE is ignored. The output is unaffected.

Testing

• Copied the script and the four *.env.sample files into an empty temp dir and ran it: exit 0, all four *.env files created, no __CHANGE_ME__ placeholders left.
• Re-ran it: "already present, nothing to do", exit 0 (still idempotent).
• Scope: one line plus a comment; no behaviour change when secrets already exist or when MYSQL_ROOT_PASSWORD / APP_TOKEN are provided.

Not included: the Dockerfile still uses the EOL python:3.11-slim-bullseye base image (apt 404s on a fresh build). That is a separate decision and is not part of this PR.
