Codex-style paste collapse for the DeepSeek Harness composer: a paste of more than 1000 characters becomes a `[Pasted Content N chars]` placeholder, a second paste of the same size is numbered `#2`, and the host expands it back to the full text before the model reads it, so the model still receives every character. A pill on the top edge of the composer shows the preview, the sent message shows the same pill, and clicking either opens the whole paste in a side panel with a copy button. Pure in memory: nothing is written to disk and no token is saved.
