Retriever Hub Pack Roadmap v1

Retriever home Core docs Visual quickstart Core source Golden overview Golden source Golden agent map

Golden is the reference catalog for applied Retriever Hub pack candidates, but not every example should be pack-loadable immediately. The rule is simple: promote examples into Hub packs only when they are import-safe, versioned, smoke-tested, and useful outside this repo.

Promotion rule

A Golden source example is ready to become a Retriever Hub pack when it has:

• import-safe top-level code,
• lightweight serializable construction config,
• no camera, robot, simulator, GPU, socket, model-key, or file opening at import time,
• a named Pixi smoke command,
• a documented expected artifact,
• clear dependency level: source-only, optional model, optional simulator, or hardware-bound.

Current v1 pack-loadable surface

Pack	Status	Why
Applied robotics type pack	Live in pyproject.toml	Stable, import-safe, useful across examples.
Arrow conversion helpers	Live in pyproject.toml	Needed for data interchange and smokeable without hardware.

Best next Retriever Hub pack candidates

Candidate	Source lane	First smoke	Promotion notes
golden.perception.synthetic_color	examples/advanced/perception_examples	pixi run -e golden-local demo-perception-detection-flow	Good first flow pack: deterministic, no hardware, typed payloads.
golden.memory.belief	examples/advanced/memory_examples	pixi run -e golden-local demo-memory-belief-flow	Good stateful Flow reference for belief and partial observability.
golden.language.caption_plan	examples/advanced/language_examples	pixi run -e golden-local demo-language-caption-plan	Good language payload reference; keep model-backed variants optional.
golden.composition.counter	examples/advanced/core_composition	pixi run -e golden-local demo-composable-pipelines	Good pipeline-as-Flow and registry composition reference.
golden.visualization.pipeline_html	examples/experimental/visualization	pixi run demo-pipeline-html-viz	Useful as a graph inspection artifact; decide whether it belongs in core or Golden before export.
golden.robosuite.lift_mock	examples/advanced/robosuite_lift	pixi run demo-robosuite-mock	Keep mock-first; real robosuite should remain optional.

Keep source-only for now

These are useful references but should not be promoted as Hub packs until their dependency and import contracts are tighter:

• unpromoted design-pattern extracts — useful as references, but not first-run runnable lanes.
• model-backed real perception and memory lanes — useful, but require explicit model/key/dependency story.
• simulator-heavy or hardware-bound lanes — keep mock-first and optional.
• browser/operator surfaces — need README, task, expected artifact, and dependency story before promotion.
