# DESCRIPTION: Phase 1 — ensure the production Qwen GGUF is present on disk.
#              Idempotent: reuses the stat + size-threshold guard pattern.
#
#              HISTORY (2026-08-06): This file previously downloaded Phi-4-14B
#              (aux, port 8000) and Mistral-Small-24B (tool-calling, port 8001).
#              Both were retired on 2026-08-06 when the deployment was
#              consolidated to a single model (Qwen2.5-14B-Instruct-1M, port
#              8002). The download tasks and VRAM co-residency logic were
#              removed from this file; see git log if a rollback needs them.
#
#              HISTORY (2026-08-07): Qwen2.5-14B-Instruct-1M was superseded by
#              Qwen3.6-35B-A3B-UD-Q4_K_S (see task t_2ffc0f63). The model
#              was downloaded out-of-band (direct wget per t_2ffc0f63 runbook)
#              rather than via this role's get_url pattern. The path and
#              variables below are updated to reflect the current production
#              model; the download task is a no-op if the file is already
#              present (which it is on astro-orbiter as of 2026-08-07+).
#
#              2026-08-12 (t_0cca74a2): Cleaned up stale Phi-4/Mistral tasks
#              that referenced undefined variables after the Aug 2026
#              consolidation. models.yml now only manages the Qwen3.6-35B
#              model that is the sole production model.
