damascus-t1b-v4l1

GGUF artifact for DAMASCUS test T1b (test plan v2.1).

• Source: tpn-004 candidate v4 final, L1-im layout — the bytes behind the official Fluid 0.5679 submission (L1-im.gguf, sha256 13d6a4a6a28d8c33...). Q4_K_M quantized by llama.cpp b10020 with the evaluator-shaped imatrix; Q8_0 for attn_q/k/v/output, ffn_down, token embeddings and output tensor.
• Template variant T1b: the shipped 305-char Mistral [INST] chat template with one edit — the system instruction is prepended as its own [INST] ... [/INST] block right after bos_token (byte-identical to how the shipped template renders a system message). Instruction: "If the question offers lettered answer options, begin your reply with exactly: The answer is (X). where X is the letter, then give one sentence of justification. Otherwise answer the task exactly as asked."
• Weights: byte-identical to the source (all 363 tensor sha256s verified equal; only tokenizer.chat_template differs). Template sha256 ca9cf390b6280a2c71faf9f15722380a9fadcf899973cf93e2db1a2fc9f2b559.

The single file model.gguf is the complete artifact.
