        "The generated conversion adapts the maintained HF client_with_eval.py, server_model.py, and job.py assets instead of drafting another loop or probing Recipe, persistor, class-loader, simulator, or argument-transport implementation source.",

        "The generated client does not implement manual FLModel receive/send model exchange.",
        "The model, datasets, TrainingArguments, and Trainer are constructed once before the FL round loop.",
        "The agent encodes a prompt-specified local budget once in Trainer max_steps or num_train_epochs and lets flare.patch infer it; when the prompt is silent it reports max_steps=10 unless source-budget preservation was requested, and it does not interrupt a valid run because cumulative max_steps covers all rounds.",
        "The round loop calls trainer.evaluate() before trainer.train() so accuracy describes the received global model.",
        "The generated job imports FedAvgRecipe from nvflare.app_opt.pt.recipes.fedavg after recipe show confirms it.",
        "The agent treats recipe show as recipe metadata only, uses SimEnv with recipe.execute for local validation and standard export flags, and does not guess a separate export environment, private class-loader helper, internal command splitter, or another recipe-adjacent API.",
        "The agent establishes host-provided NVFLARE availability separately through nvflare agent inspect source, nvflare --version, or a public capability check before generic package inventory; it never includes nvflare in a batch of importlib.metadata lookups, handles missing non-product metadata as an inventory result rather than a failed command, and skips installation when all applicable requirements are already compatible.",
        "The agent keeps dependency inventory separate from optional Hugging Face cache or filesystem discovery, defers model and dataset availability checks to the maintained resolver, and makes any separately necessary missing-path probe exit zero.",
        "The agent tells the maintained resolver whether each model identifier is a local path or Hub repository ID instead of inferring from slash syntax. When public checkpoint download is authorized if uncached, it uses one normal cache-aware load pinned to a full immutable commit SHA instead of an unguarded cache-only probe that fails on a normal miss.",
        "A generated or preserved HfArgumentParser is constructed with allow_abbrev=False. Intentional typo and abbreviation rejection checks run through assertion wrappers whose top-level commands succeed only when the generated parser rejects them; the wrapper accepts an expected unused-argument ValueError only when its diagnostic names the rejected argument.",
        "Standalone preflight may construct the Trainer but does not call flare.init(), flare.patch(), flare.is_running(), or patched Trainer methods without a launcher-created Client API context; the first bounded simulation validates runtime patch acceptance.",
        "The generated recipe model is an explicit class_path and args mapping, not a live model instance. Validation reconstructs the source and server models through the same importable factory path and arguments and compares keys, shapes, and dtypes. Before comparing values, it uses source or load-report evidence to distinguish checkpoint-loaded parameters from missing or newly initialized parameters, requires exact values or a stable state hash only for parameters proven deterministic, and does not create a failed top-level command by unconditionally comparing independently initialized keys.",
        "The generated job preserves the maintained PyTorch-family fast path: FedAvgRecipe with class_path, SimEnv, recipe.execute, and explicit server/client model-file packaging.",
        "The generated recipe uses ExchangeFormat.PYTORCH, enables tensor disk offload, encodes train_args for the selected public execution mode without assuming shell parsing, and packages the required model file into the server app with recipe.add_server_file or an equivalent server-targeted API, including a server-only model.py that would otherwise be outside each client app's train_script import closure.",
        "The recipe key_metric preserves the source metric name accuracy when the generated evaluate call emits accuracy; if Trainer emits eval_accuracy, the recipe uses that exact key and reports the source-to-server metric mapping.",
        "The two simulated clients train on deterministic seeded site-local partitions, stratified when labels exist, rather than the same full training dataset; the report names the split policy, seed, site count, and any shared-data request.",
        "The agent capability-checks optional host diagnostics such as free or nvidia-smi, runs them separately from required validation, and makes their absence an exit-zero evidence result so a missing utility cannot fail otherwise successful parser, partition, or model-keyspace validation.",
        "The agent validates through compile/import, recipe construction, bounded simulation, and result evidence, stopping on a real failure.",
        "The final report includes source facts, changed files, recipe, commands, validation status, and exact artifact paths, and writes every artifact-backed primary metric as its name, numeric scalar, and source."
