Smoke-test v2 surfaced that S13 (auxiliary.session_search.default_mode: summary)
went fast→guided 5/5 iterations instead of respecting the user's configured
summary default. The agent passed mode='fast' explicitly on every first call,
ignoring the config.
Root cause: the 'respect the configured default' guidance lived at the very
bottom of the schema description, after all the 'fast → guided is best' teaching.
The general guidance was louder than the user-preference clause.
Fix: hoist USER-CONFIGURED DEFAULT to the top of the description, framed as
something the agent should check FIRST. Strengthen the language: honour the
user's configured default on the first call unless the question shape
categorically requires a different mode. Don't override the user just because
the general guidance says fast→guided is best.
Replace the redundant bottom paragraph with a brief pointer to the top.
No code changes — schema description only. Tests still 99/99.
