Extract the replay-based retargeting path into a self-contained `autodata_retargeting` package plus `scripts/retarget_dataset.py`. Each source demo is replayed 1:1 onto a target embodiment: the recorded EEF pose trajectory is re-encoded through the target's IK env, one output demo per input demo. Features: - Per-EEF subtask segmentation from source events (gripper/signal edges, fixed length), with motion-aware boundary settling. - Hand policies (passthrough / binary / interpolation / joint_mapping) and non-EEF passthrough channels. - Object tracking over a subtask (rigid eef_T_object) with eased interp. - Per-subtask SE(3) offsets over a continuous timeline (adjacent segments blend; last subtask holds its offset). - Parallel multi-env replay (--num_envs) for throughput. - Optional datagen_info export -> drop-in generate_dataset source. Ships G1 ⇄ GR1T2 pick-and-place descriptors and g1/gr1 IK-abs embodiment descriptors; works with single-arm embodiments too. Adds a copy-mode usage guide in autodata_retargeting/README.md.

📝 WalkthroughWalkthroughAdds a cross-embodiment retargeting package. It defines YAML schemas, EEF and hand remapping, trajectory processing, object tracking, replay execution, parallel scheduling, CLI orchestration, documentation, and bidirectional pick-and-place descriptors. ChangesCross-embodiment retargeting
Priority: ➖ Normal Estimated code review effort: 5 (Critical) | ~120 minutes Change: Feature Merge Risk: 🟡 Moderate · up to This change adds a substantial new cross-embodiment dataset retargeting tool. A configuration bug means writing a quoted "false" value for options like init_robot_from_ik or stop_early_on_failure will unexpectedly enable that behavior instead of disabling it, and misspelled configuration keys are silently ignored rather than flagged. Separately, an unresolved crash bug can abort retargeting runs whenever a configured subtask-ending event never fires. None of these represent data loss or security exposure, but they can produce silently incorrect retargeted output or aborted runs and should be fixed before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Inline comments:
In `@autodata_examples/retarget/g1_to_gr1_pick_place.yaml`:
- Line 65: Add a trailing newline after the final description value in the YAML
file so it satisfies the end-of-file-fixer hook.
In `@autodata_examples/retarget/gr1_to_g1_pick_place.yaml`:
- Line 69: Remove the extra trailing blank line from the YAML file, leaving
exactly one newline at end of file.
In `@autodata_retargeting/gripper_retargeting.py`:
- Around line 223-226: Extend the posture validation loop around
target_eef_names to validate both open and close postures for every target EEF,
checking each against target_layout[eef_name]. Also validate source postures
using source_layout with eef_name_map applied only to select the source layout
key, while retaining the existing target-name storage and error behavior.
In `@autodata_retargeting/object_tracking.py`:
- Line 119: Update the warnings.warn call in _event_step’s unfired-event
fallback to pass 2 as the stacklevel keyword argument, preserving the
trajectory-end fallback when no transition is found.
In `@autodata_retargeting/parallel_replay.py`:
- Around line 88-90: Update _replay_one_episode’s return annotation and
docstring to describe its two-value return tuple: the task success status and
passthrough action dictionary. Keep the return value at line 276 and
_replay_worker’s two-value unpacking consistent with this contract.
- Line 1: Run the configured Black formatter on parallel_replay.py using the
repository’s pinned 120-character line length, ensuring the _async_step
signature and any other formatting match Black 24.3.0 output.
In `@autodata_retargeting/provider.py`:
- Line 1: Run Black formatting on provider.py and remove the trailing blank line
so the file matches the configured formatter output.
- Around line 118-132: Update DatasetReplayProvider’s _target_reached logic to
enforce target_runs using the number of handed-out plans (_handed_out), while
leaving the target_successes condition unchanged. Ensure next() stops issuing
plans once the handed-out count reaches the configured target_runs, preventing
excess in-flight plans in parallel execution.
In `@autodata_retargeting/replay.py`:
- Line 1009: Update the return annotation of replay_episode_on_target to
describe exactly two returned values, removing the unused third tuple element
while preserving the existing types of the boolean and dictionary results.
In `@autodata_retargeting/replayer.py`:
- Around line 1-4: Replace the copyright header in replayer.py with the
configured insert-license header: use “Copyright (c) 2026 NVIDIA CORPORATION &
AFFILIATES. All rights reserved.” followed by “SPDX-License-Identifier:
Apache-2.0”, preserving the hook’s required format.
In `@autodata_retargeting/runner.py`:
- Around line 138-143: Update the runner cleanup flow to explicitly close the
HDF5 dataset handler in the existing finally block, including empty-dataset,
successful-return, and exception paths. Construct HDF5DatasetFileHandler before
the try block, then call its close() method alongside the existing env cleanup.
In `@autodata_retargeting/util.py`:
- Around line 1-4: Replace the existing header in util.py with the
repository-configured license header from .github/LICENSE_HEADER.txt, preserving
the file’s Python content unchanged.
In `@scripts/retarget_dataset.py`:
- Around line 49-50: Update the note near the retargeted output description to
reflect that write_datagen_info preserves forwarded subtask_term_signals in
obs/datagen_info. Remove the instruction to rerun annotate_demos.py solely to
restore subtask signals, while retaining any guidance still needed before using
the output with generate_dataset.py.
- Around line 151-156: Wrap the run(args_cli, simulation_app) invocation and
KeyboardInterrupt handling in a try/finally structure so simulation_app.close()
executes on every exit path, including unhandled exceptions, while preserving
the existing interruption message.

Validate all source and target hand postures against their layouts.
Only the target open posture is checked. A wrong-width source posture can broadcast in _hand_close_fraction. A wrong-width target close posture can broadcast in the binary or interpolation policies, or fail later during tensor mapping.
load_hand_postures stores source postures under target EEF names, but source_layout uses source EEF names. Apply eef_name_map only when selecting the layout key:

Pass stacklevel by keyword in the unfired-event fallback.
When a non-final gripper or signal event has no transition after start, _event_step returns None. The imported warnings.warn treats the second positional argument as category, so 2 raises TypeError instead of returning the trajectory-end fallback. This aborts retargeting runs for those configurations, but it is not a broadly release-blocking failure.

Isaac Lab isaaclab.utils.datasets HDF5DatasetFileHandler source close method
💡 Result:
<search_synthesis>
In the Isaac Lab library, the close method within the HDF5DatasetFileHandler class is responsible for safely closing the HDF5 dataset file stream [1][2]. The implementation of the close method is as follows [1][2]: def close(self): """Close the dataset file handler.""" if self._hdf5_file_stream is not None: self._hdf5_file_stream.close self._hdf5_file_stream = None This method first checks if the file stream (self._hdf5_file_stream) exists and is not None [1][2]. If it is active, it calls the close method on the underlying h5py file object and subsequently sets the handler's internal file stream reference to None to indicate that the file is no longer open [1][2]. Additionally, the class includes a destructor (del) that automatically invokes self.close to ensure the file stream is closed when the object is garbage collected [1][2].

Close the HDF5 dataset handler in finally.
HDF5DatasetFileHandler opens an HDF5 stream. The empty-dataset return, successful return, and exception paths all reach finally, which currently closes only env. The handler destructor eventually closes the stream, but explicit cleanup avoids retaining the file until garbage collection.
Construct the handler before try. Its close() method is safe when no stream was opened.

Lucas-C pre-commit-hooks insert-license --remove-header existing license header behavior v1.5.1
💡 Result:
<search_synthesis>
In the Lucas-C pre-commit-hooks repository, the --remove-header argument for the insert-license hook is designed to remove existing license headers from files [1][2]. According to the official documentation, if you need to remove license headers—for instance, to update the wording of your license—you should follow this process [1][2]: 1. Temporarily add the --remove-header argument to your.pre-commit-config.yaml configuration [1][2]. 2. Execute the hook across all your files using the command: pre-commit run insert-license --all-files [1][2]. 3. Remove the --remove-header argument from your configuration and update your LICENSE.txt file [1][2]. 4. Re-run the hook on all your files to apply the updated license headers [1][2]. When using --remove-header, the hook will remove existing license headers regardless of the years they contain, effectively treating them as if they matched the year currently present in your license file [1][2]. This behavior remains consistent across versions, including v1.5.1 [1][2][3].

Update the stale note about subtask signals.
This note tells the user to re-run annotate_demos.py because subtask signals are not carried over. The write_datagen_info option now writes obs/datagen_info including the forwarded subtask_term_signals, and both example descriptors enable it. Describe the current behavior so users do not run an unnecessary annotation pass.

-Note: the output records target actions + states. Re-run ``annotate_demos.py`` on it before using
