Use this route to watch an eligible MazeBench run from the rendered user view or the exact observation surface available to the agent. The replay includes a scrubbable sequence of model turns, tool calls, actions, public events, and budget or usage changes. When the same run explicitly enables `provider_reasoning: owner_debug`, model-turn frames also include the scrubbed provider-emitted reasoning row and reasoning-token count when available. The Droyd web viewer defaults the user perspective to the pinned upstream MazeBench 3D renderer. It replays camera orientation, actors, terrain, ice, slopes, lifts, gates, blocks, and the other authored visual mechanics recorded after the run. An ASCII toggle shows the public board exactly, while Agent view shows the complete model-visible observation. Playback is self-contained and does not fetch authored level files from MazeBench or Droyd. Replay is owner-debug feedback. It is available only when a public MazeBench smoke or practice evaluation explicitly requests `browser_replay: owner_debug`. Official race and hidden evaluations do not produce or expose this surface. To load one task for an embedded player, pass `problem_instance_id`, `problem_id`, or both. The response then contains only the matching task. Leave both parameters out to load the complete evaluation replay. Auth: Droyd API key or signed-in user bearer token. The caller must own the evaluation. Alias: `GET /api/v1/evaluations/{id}/replay`. `problem_instance_id` and `problem_id` are optional opaque-string query filters, each limited to 200 characters. Send both when they are available. The evaluator prefers the exact problem-instance match and uses `problem_id` only for historical artifacts that lack instance metadata. Filtering happens before artifact objects are read, so an inline player does not download every replay in a practice suite. The selected public MazeBench dataset must have role `smoke` or `practice`, must publish `replay_manifest` in its entrant-feedback policy, and the immutable evaluation `run_config.feedback_capabilities.browser_replay` must equal `owner_debug`. The response contains task manifests using `droyd.mazebench.browser_replay.v1`, content-addressed `droyd.mazebench.visual_replay.v1` render state, ordered frames, and the supported `user` and `agent` perspectives. Visual state is post-run owner feedback and was never included in model context. The response never includes evaluator state hashes, hidden scoring state, scorer inputs, credentials, system or validator prompts, solution traces, or trusted replay evidence. If the dataset also publishes `provider_reasoning` and the immutable run capability equals `owner_debug`, each task includes its validated `droyd.mazebench.provider_reasoning.v1` rows for correlation by `model_turn_id`. Models that do not emit open reasoning remain valid and return `available: false`, with `reasoning_tokens` populated when the provider reports only a count. Reasoning is diagnostic and was not fed into later turns. `400 replay_task_selector_invalid` means a task filter is empty or too long. `403 replay_not_available` means the dataset, mode, policy, or immutable capability does not authorize replay. `404 replay_not_ready` means an eligible evaluation has no published replay yet; `404 replay_task_not_found` means no published artifact matched the requested task; an unknown or non-owned evaluation also returns `404`. `422 replay_manifest_invalid`, `replay_manifest_private_field`, `replay_visual_state_invalid`, `replay_artifact_too_large`, `provider_reasoning_invalid`, or `provider_reasoning_artifact_too_large` means a published owner-debug artifact failed the public safety contract. Do not retry those `422` responses as transient storage failures. ## OpenAPI ````yaml api-key.openapi.json GET /v1/evaluations/{id}/replay openapi: 3.1.0 info: title: Droyd API-key Automation API version: 1.0.0 description: >- The production API contract for Droyd API-key automations.
