"""
Wave 0 xfail stubs for quota enforcement tests — Plan 03-02 implements these.

Requirements covered:
  STORE-03 — Atomic quota enforcement at upload (no double-spend)
  STORE-03 SC2 — Two concurrent uploads at quota limit → exactly one 413
  STORE-05 — Confirm endpoint returns 413 with {used_bytes, limit_bytes, rejected_bytes}
  STORE-06 — Document delete atomically decrements quota
