Sage curated corpus: 2791 rows (was a partial ~17-row snapshot from Aug 7) + full HOLD backlog reconciliation

Add self-eval loop curated examples (Sage's own judgment, real HOLD option, persona-denial rule) - 11 examples so far

Fix: chunk oversized examples (max 11k chars -> max 971) that caused NaN loss during training

Add dataset card

Initial public corpus: redacted flock_dreams + memory, 9175 examples
