"""Load, soak, and resource-budget harness (US07-06, concept §17 and §18).
Performance here is not "it felt fast on my library". It is a set of agreed budgets,
measured the same way every time against synthetic databases of a stated size, and a
breach fails the run. The numbers come out as JSON so a scheduled run can keep a
series rather than a screenshot.
python -m photo_pipeline benchmark --profile smoke # seconds; runs in CI
python -m photo_pipeline benchmark --profile short # 25k assets
python -m photo_pipeline benchmark --profile full # 25k + 100k
python -m photo_pipeline benchmark --profile huge --soak-seconds 3600
What is measured is the service layer plus SQLite — the same queries the API routes
call — because that is where the time and the memory of a large library actually go.
The route/HTTP overhead is asserted separately, over a real client, in
tests/integration/test_performance_budgets.py.
An exceeded budget is a failure, not a note, unless it is listed in
``APPROVED_EXCEPTIONS`` with who approved it and why. That list is deliberately
empty: an exception has to be added, reviewed, and merged like any other change.
