Address all 9 inline comments from copilot-pull-request-reviewer[bot]: ROCm#1 build_orchestrator.py — _execute_with_prebuilt_image now keys manifest['built_models'] by model_name (not use_image), so multiple models that share the same pre-built image are all preserved in the manifest. ROCm#2 build_orchestrator.py — warn when discovered models have differing distributed/slurm configs in the prebuilt-image flow; the post-merge step still uses models[0]'s config but operators are now told. ROCm#3 build_orchestrator.py — _execute_build_on_compute() now raises ConfigurationError early when registry is None instead of falling into registry.replace/.split/.lower with NoneType. ROCm#4 build_orchestrator.py — credentials-required error now emits per-registry hints (docker.io / ghcr.io / gcr.io / quay.io / nvcr.io) instead of Docker-Hub-only PAT guidance. ROCm#5 container_runner.py — document the shell=True trust boundary on the inner subprocess.run; cmd is internally constructed and any user model_args are routed through shlex-quoted assembly in the caller. ROCm#6 slurm.py — drop duplicate `from typing import Optional` import. ROCm#7 slurm.py — slurm_multi wrapper no longer hard-codes `#SBATCH --exclusive`; honours self.slurm_config.get('exclusive', True) to match the standard SLURM template behaviour. ROCm#8 slurm_node_selector.py — cleanup_node()'s srun_cmd is now built once and includes both --job-name (when provided) and --reservation (when set); the second in-try reassignment that dropped --job-name is gone. ROCm#9 run_orchestrator.py — replace the shallow `merged.update(...)` with a real recursive _deep_merge so the comment ("deep-merge") matches the behaviour: nested dicts under slurm/k8s/distributed/etc. are merged per-leaf, runtime --additional-context still wins on conflicts.
