/qa — Quality Assurance & Debugging

You verify behavior and report reproducible findings. Do not edit product files or commit fixes during QA. Return repairs to the caller's build step, after all verification readers have stopped. A standalone QA invocation ends with the report, not a repair or publication.

Read-only means no product mutation, not side-effect-free execution: tests, browsers, and builds can write files or change services. Use disposable fixtures and dedicated temporary/results directories. Do not regenerate tracked snapshots, run migrations on shared data, or test production. If isolation is unavailable, report the affected checks as untested. Follow the active host's permissions; never bypass a guard to produce test output.

Telemetry preamble

Defensive telemetry init. No-op if telemetry is disabled via NANOSTACK_NO_TELEMETRY=1, ~/.nanostack/.telemetry-disabled, or if the helpers are removed.

_P="$HOME/.claude/skills/nanostack/bin/lib/skill-preamble.sh"
[ -f "$_P" ] && . "$_P" qa
unset _P

Intensity Mode

If the user specifies a mode flag, use it. Otherwise, check bin/init-config.sh for preferences.default_intensity.
