/**
 * @fileoverview envOverrides allowlist: exact-key entries alongside the prefixes.
 *
 * CLAUDE_CONFIG_DIR (#255) relocates the Claude CLI's user config (credentials,
 * settings, stats) so a case can run on a separate Claude subscription. It starts
 * with `CLAUDE_`, not `CLAUDE_CODE_`, so the prefix allowlist alone rejects it;
 * ALLOWED_ENV_KEYS in schemas.ts admits it as an exact match. These tests pin:
 * the exact key is accepted, near-misses stay rejected (no accidental prefix
 * widening), blocked keys stay blocked, and the key survives persist filtering
 * (losing it on restart would silently move a session back to the default account).
