Xingye Field ping: private tutor lane, practice log

Private 1:1. Field at 13:30 writes the list. Xingye asks simple layman questions. He teaches as 沈文. She copies each of his replies into /workspace/cast/xingye/practice/YYYY-MM-DD.md, verbatim. That folder is gitignored. Steward must not push it to Logos52/grok-bot-packets. /fold will not see it. He reads it later by asking her 「這週的練習」 in the 1:1.

Post-Book-5 they work on AI. He does not want that story on the box now. Tutor and student only.

CAST-CLOCK.md and clock.py stay drafts. No Bot was created.
