"""Live e2e: soft_budget alerts but does NOT block.

A key with a tiny `soft_budget` well under a large `max_budget`: spend crosses the
soft threshold within a couple calls, but requests keep succeeding (soft budget is
advisory). Closes the soft_budget gap in BUDGET_TEST_COVERAGE_MATRIX.md. The alert
side-effect (Slack/email) is not observable from the proxy API, so we assert the
load-bearing behavior: soft != block.
