Task 14's session read the crate to learn the APIs and planned `connect` in prose until it was cut off. `connect`, `Gateway::new` and `catch_up` are now written; the task lists every call with its signature and makes the copy and the failing test the first actions. Task 15's comment is rewritten one step per item. Both checked to fail, then pass when filled from their comments. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
