Distil SN97 hotkey rotation bug blocks new evaluations

UID 3 (best26/sn97-rn-v11) holds the king position with a 0.489 composite score. The subnet deployed critical anti-spam fixes on May 20 — one-eval-per-hotkey lock, per-coldkey caps, and wipe-forensics monitoring — but introduced a regression: new hotkeys registering at previously-evaluated UID slots cannot enter the eval queue because stale composite scores block challenger selection. The eval queue is now empty pending new submissions and a hotfix to clear scores when hotkey identity changes at a UID.

• •UID 3 defends crown; eval queue depleted, awaiting new model submissions
• •Anti-spam fixes deployed: one-eval-per-hotkey lock, 2-UID-per-coldkey cap
• •P0 regression: hotkey rotation blocked by stale UID-keyed composite scores
• •Wipe-forensics monitoring deployed; three working-tree incidents logged May 18–20
