batch-size defaulted to 2048 (capping ubatch) and ctx 8192 over 4 slots left 2048 per slot, so Honcho inputs over 2048 tokens failed with 'input is too large to process'. Now batch/ubatch 8192, ctx 16384 over 2 slots = 8192/slot, matching Honcho's EMBEDDING.MAX_INPUT_TOKENS. Verified a 6191-token input.
