EBC-JEPA per-event LED denoising: carrier "k groups (equal count)"

Frozen V-JEPA 2.1 tokens on LED, tokenised as k groups (equal count) (each cell's events cut in time order into 8 groups of equal count, re-laid by tubelet), scored per event: each event looks up the token at its (time bin / 2, patch) and is judged with its own E15 neighbourhood patch. Routes in this repo:

• V12 AC: token + E15 patch CNN, no history (v12_ac/).
• Integrated: History Reader (kv) conditions the token on earlier chunks, a TemporalViT reads the patch, and Pixel-AC fuses the per-event scores into one decision per pixel and chunk (integrated/<run>/; result.json carries the Pixel-AC metrics with the AC-only metrics under ac). Run-name suffixes: _nokv = reader bypassed, _lb = scalar Local branch on, _vit_base = ViT-B/384 tokens.

All units: 6,000 training chunks, 4 epochs, official 713 chunks at a fixed threshold of 0.5, no selection on test.
