__pydantic_extra__ as dict[str, JsonValue] = Field(init=False), ensuring extra
task inputs are validated as JSON values. Add a test covering rejection of a
non-JSON extra value.

task.inputs.model_dump to preserve None-valued extra inputs by dumping all
fields, while removing only a None instruction so the existing intent fallback
remains unchanged. Add a round-trip assertion covering a null extra field such
as gym_row.

The rebase onto main's promptless-row handling (which independently touched discover_gym_tasks) surfaced tests still asserting gym_row lives under inputs. It moved to metadata earlier in this branch, since the wire-facing TaskInputs DTO only recognizes `instruction` and has nowhere else for an arbitrary dataset row to travel through a submitted job spec.

The Gym runner shipped with no documentation. "Gym" appeared nowhere in `docs/`, even though `GymAgentTaskRunner` sits alongside the Callable and Harbor runners in the SDK and `GymRunnerTarget` alongside Codex, Fabric, and Harbor in the job spec. Targets and Runners was also wrong about the one thing readers copy from it. `AgentTaskRunner` is a two-member protocol -- `run_tasks` *and* `runner_info` -- but the page called it "the one-method protocol", showed only `run_tasks`, and its `EchoRunner` example omitted `runner_info`. That example does not work: being `@runtime_checkable`, the protocol rejects the class, and the run dies with `NotImplementedError: unsupported agent-eval target type: EchoRunner`, naming neither the protocol nor the missing method. Fixed, and the failure mode is now stated so the error is searchable. Adds "Evaluate a NeMo Gym Environment" beside the Harbor page, which had the same shape already: an example README in `examples/gym/` and no doc. It covers install and the `PATH` constraint, credentials, task discovery, the config reference, results, output directories, the two-step Gym invocation, and submission as a platform job. DEPENDS ON #1315. The submission section stores Gym rows on a taskset, which needs both halves of that PR: `TaskInputs` going `extra="forbid"` -> `extra="allow"` so `inputs['gym_row']` is accepted, and `MetadataItem.value` going `str` -> `JsonValue` so `metadata['gym_row_extras']` survives as a dict. On current main the documented snippet raises `TaskInputs / gym_row / Extra inputs are not permitted`. Worth noting that the docs snippet linter does NOT catch this -- `TaskInputs(**task.inputs)` hides the extra keys from static analysis -- so CI cannot gate it. Do not merge ahead of #1315. Everything here was executed rather than read. A throwaway venv with `nemo-gym` installed ran three live evaluations against mcqa, which caught four errors in my own draft: `agent_config` was `configs/simple_agent.yaml` where the real value is `responses_api_agents/simple_agent/configs/simple_agent.yaml`; `result.summary.scores` does not iterate scores (`.scores.scores` does); `work_dir` needs a `Path`; and the page never showed how to set an output directory at all. The score names, the 0-100 vs 0-1 scale note, and the `gym_run/` artifact list are copied from real output. The submission snippet was executed verbatim against #1315's branch, and two more traps came out of it: a task cannot be named after `task.id` (a 64-char hash starting with a digit, against a 63-char cap requiring a leading letter), and `GymRewardMetric` is not a built-in type so the inline packager rejects it. Two fixes outside the docs tree, both found while sourcing from the example: `examples/gym/README.md` said to install Gym "in the same environment as the SDK". The source says the opposite, and it is right -- Gym imports Ray at module load and nemo-platform excludes Ray by constraint. Its "Next steps" also linked `runtimes/gym_runtime.py`, which became the `runtimes/gym/` package; split into live links to `config.py` and `runtime.py`. The reuse guard's `FileExistsError` told the caller to "give each run a fresh output_dir". There is no such parameter -- it is `AgentEvalRunConfig.work_dir` -- so the message sent readers looking for an argument that does not exist.

Fixed, and the failure mode is now stated so the error is searchable. Adds "Evaluate a NeMo Gym Environment" beside the Harbor page, which had the same shape already: an example README in `examples/gym/` and no doc. It covers install and the `PATH` constraint, credentials, task discovery, the config reference, results, output directories, the two-step Gym invocation, and submission as a platform job. Adds "Evaluate with a NeMo Fabric Harness" alongside it. Fabric was the other shipped runner with no documentation at all -- absent from the whole `docs/` tree despite covering four harnesses through one config. The page documents the adapter map, the agent-config shape, the ATIF trajectory that distinguishes this runner, and the sandboxed `FabricContainerRuntime`. Codex and the OpenAI-Agents Docker sandbox are deliberately left undocumented: the Codex runner is being removed in #1419, and `DockerSandboxAgentRuntime` is stranded by the same PR (it existed only as the `sk-...`-key branch of ProfBench's Codex path) and is expected to follow it. The Fabric page is verified the same way: its config and run blocks execute verbatim against a real Fabric -> Codex -> Relay evaluation, producing a completed trial with an `atif` trajectory. That caught two defects in the draft -- `work_dir` needed a `Path`, and the example task declared `metrics=[]`, which the evaluator rejects outright. `FabricContainerRuntime` is documented from source rather than run: its own tests use a fake sandbox provider, so there was nothing live to exercise. Everything here was executed rather than read.

The Gym runner shipped with no documentation. "Gym" appeared nowhere in `docs/`, even though `GymAgentTaskRunner` sits alongside the Callable and Harbor runners in the SDK and `GymRunnerTarget` alongside Codex, Fabric, and Harbor in the job spec. Targets and Runners was also wrong about the one thing readers copy from it. `AgentTaskRunner` is a two-member protocol -- `run_tasks` *and* `runner_info` -- but the page called it "the one-method protocol", showed only `run_tasks`, and its `EchoRunner` example omitted `runner_info`. That example does not work: being `@runtime_checkable`, the protocol rejects the class, and the run dies with `NotImplementedError: unsupported agent-eval target type: EchoRunner`, naming neither the protocol nor the missing method. Fixed, and the failure mode is now stated so the error is searchable. Adds "Evaluate a NeMo Gym Environment" beside the Harbor page, which had the same shape already: an example README in `examples/gym/` and no doc. It covers install and the `PATH` constraint, credentials, task discovery, the config reference, results, output directories, the two-step Gym invocation, and submission as a platform job. Adds "Evaluate with a NeMo Fabric Harness" alongside it. Fabric was the other shipped runner with no documentation at all -- absent from the whole `docs/` tree despite covering four harnesses through one config. The page documents the adapter map, the agent-config shape, the ATIF trajectory that distinguishes this runner, and the sandboxed `FabricContainerRuntime`. Codex and the OpenAI-Agents Docker sandbox are deliberately left undocumented: the Codex runner is being removed in #1419, and `DockerSandboxAgentRuntime` is stranded by the same PR (it existed only as the `sk-...`-key branch of ProfBench's Codex path) and is expected to follow it. The Fabric page is verified the same way: its config and run blocks execute verbatim against a real Fabric -> Codex -> Relay evaluation, producing a completed trial with an `atif` trajectory. That caught two defects in the draft -- `work_dir` needed a `Path`, and the example task declared `metrics=[]`, which the evaluator rejects outright. `FabricContainerRuntime` is documented from source rather than run: its own tests use a fake sandbox provider, so there was nothing live to exercise.

Summary
Adds end-to-end coverage and production image support for Gym-backed agent evaluation.
Gym evaluations now run in a dedicated, releasable
nmp-gym-tasksimage containing Gym and Ray in an isolated virtual environment. The sharednmp-cpu-tasksimage remains unchanged and does not include those dependencies.Changes
