Subject: [PATCH] fix: 7-day TTL on dated learnings + block availability
 learnings

Stale learning ("I don't have Robin Hanson data") overrode real KB data.
Ganymede review: dated entries expire after 7 days. Permanent entries
(communication style, identity) are undated and always included.

Prompt guard: "NEVER save a learning about what data you do or don't have"
prevents the bot from writing availability claims that go stale.
