 **lightcone-cli** is Lightcone Research's agentic layer for ASTRA (Agentic Schema for Transparent Research Analysis). It ships the `lc` executable and Claude Code skills/hooks used during interactive analysis work.
 
 - **ASTRA** = pure specification: schema, validation, prior insights & findings, evidence verification, helpers, minimal CLI

 lightcone-cli depends on ASTRA. The `astra` CLI handles spec operations; the `lc` CLI handles execution and agent operations.

 `lc export wrroc` walks your manifests and emits a [Workflow Run RO-Crate](https://www.researchobject.org/workflow-run-crate/) bundle — a JSON-LD package readable by WorkflowHub, Zenodo's RO-Crate plugin, and any RO-Crate-aware archive. Each materialization becomes a `CreateAction` with `object` (inputs, including upstream datasets via stable `@id` references) and `result` (the output dataset); decisions become `PropertyValue` entities; the workflow is captured as a `ComputationalWorkflow`. The lightcone manifest format on disk is unchanged — WRROC is the publication view, generated on demand. Use `--metadata-only` to ship only the provenance graph (useful when data files are huge), `--zip` to package the bundle for upload, or `-u <universe>` to restrict to specific universes.
