Sharpa Artifacts

Public, versioned machine artifacts for the Sharpa functional-reorientation pipeline. Source code and download validators live in ai4ce/dex_retarget.

Start here: Astra trajectory augmentation

The repository now includes eight Sharpa Stage3 AutoDR residual-teacher checkpoint candidates for generating physics-executed recovery trajectories. Give an Astra agent the following guide as its execution handoff:

• Astra guide: use the Phone8 teachers for trajectory augmentation
• Immutable Phone8 checkpoint release

The intended loop is:

matching Stage2 reference
  -> bounded hand/object tweak
  -> residual-teacher recovery in Isaac/PhysX
  -> functional-pose evaluation
  -> immutable rollout + action chain + diagnostics + 2x3 video
  -> optional accepted child tweak

This release contains the teachers and collection contract. It does not claim that the proposed augmented rollout dataset has already been collected.

Layout

Artifacts are organized by object and immutable release:

Releases

phone8-stage3-autodr-candidates-v1

• Eight per-phone Stage3 residual-teacher checkpoint candidates: phone_02, phone_03, phone_05, phone_07, phone_10, phone_14, phone_17, and phone_18.
• Each episode includes its checkpoint, Training Card, checkpoint receipt and evaluation summary.
• The release also includes a Data Card, collection specification, manifest and SHA256 inventory.
• Status: CHECKPOINT_RELEASE_READY_CANDIDATES_NOT_PROMOTED.

phone20-stage12-v2

• Current Stage3-compatible Stage1/Stage2 release.
• Contains 20 accepted Stage1 NPZ files, 20 final Sharpa retargeted_moving28_60fps.h5 trajectories, human/canonical H5 files, GoalContracts, QA videos, manifests and handoffs.
• Open the 20-phone exact H5-to-video review index. These fresh renders read the final V2 moving28 H5 bytes directly; human review remains pending.

phone20-stage12-v1

• Historical first upload.
• Superseded for Stage3 because it renamed inputs/ to stage1/ and omitted the handoff-bound QA video.

Consumer contract

Pin an exact Hugging Face revision and verify release_manifest.json plus checksums.sha256 before use. A checkpoint must be paired with the matching episode's Stage2 H5, GoalContract, Training Card and runtime identity; similar filenames are not interchangeable provenance.

Checkpoint availability is not policy promotion. These candidates have not completed the full P2 robustness bank, automatic drop detection and human video review required for a robust-teacher claim. See the per-episode evaluation summary before selecting a source.

Data boundary

This repository contains derived research artifacts and selected checkpoint candidates. It does not contain raw Vicon/MANUS capture, the proposed new augmentation rollout bytes, full training logs, a self-contained Isaac image, or unrelated third-party assets. Public access does not grant rights to third-party assets; consumers remain responsible for applicable licenses.
