+# Gemma 4 E4B — v5: v4 plus the VERIFY entrypoint (full logits + activations)
+
+The same head-sidecar construction `v4/` shipped (graph constant ~0, bit-exact
+numerics — see the v4 card), plus the one thing the assistant drafter needs: a
+`verify` entrypoint, S=8, FULL logits [1,8,262144] and the post-final-norm hidden
+states as `activations` [1,8,2560].
+
+**No `accepted_count` input, deliberately.** The E-series ring is R=1024 over
+W=512, write-then-read: a verify call commits its rows (its own drafts must be
+attendable), and a REJECTED draft's row is geometry-dead — its implied position
+fails the window test until it is overwritten. Single-pass speculation, which is
+why the E4B's speculative economics beat the 12B's two-pass protocol.
+
+Measured the night it was built (python Metal runtime, CPU fp32 drafter — a
+handicapped harness): assistant drafting accepted a mean 3.20/8 per round on
+report prompts and was net-positive over vanilla decode (2.11 vs 1.81 tok/s)
+even with the drafter on CPU. `verify takes input_ids/position_ids [1,8] plus the bundle's static inputs and returns FULL logits [1,K,V] and the post-final-norm hidden states as `activations` [1,K,H]. It COMMITS...` — the full contract is in
+`metadata.json`.
+
+## Tables
+
+Pair with **`v4/ios-frontend/gemma4_e4b_qat_gather_raw/`** — the v5 dump is
+byte-identical (verified sha256 file-for-file before this upload) and is not
+duplicated here.
