Description

Fixes #1319

Add standard device-health reporting to the Sharpa Avatar plugin.

• Report the Avatar USB dongle separately using Linux USB enumeration.
• Report left- and right-glove health independently.
• Publish health for the hand, raw-joint, and robot-joint manifest paths.
• Register avatar_hand_plugin for TeleopSession status monitoring.
• Add --print-health to the existing Sharpa Viser example so health changes can be inspected from the terminal.
• Keep health collection and publication failures isolated from the tracking data path.

The pinned production Avatar SDK 1.7.3 does not expose independent “physically connected” and “data streaming” signals in wireless mode. DeviceInfo.online follows recent joint-frame activity, so this PR exposes it as the available glove health signal and uses sample freshness to prevent stale data from being reported as healthy. Dongle presence is reported independently.

No new health UI is added to Viser. Applications can consume the status through the existing TeleopSession.get_status() / get_device_status() interface, while --print-health provides a test and debugging view.

Summary by CodeRabbit

• New Features
  • Sharpa Avatar health reporting now shows USB dongle status and separate left- and right-glove status, including when data is stale or unavailable.
  • The Sharpa Avatar example can optionally print device health at startup and whenever health changes.
• Documentation
  • Updated the example’s run instructions and clarified how device and wireless-stream health are reported.

Walkthrough

The Sharpa plugin now reports health for each glove’s hand, raw, and robot paths, and for the USB dongle. Glove status uses SDK online state and sample freshness. TeleopSession monitors the Avatar plugin, and the example can print initial health and subsequent changes. The change also adds health-state tests and repository guidance for local dependencies.

Priority: Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Severity of issue fixed: Medium

Merge Risk: Moderate · up to 9d95a

Glove health can incorrectly report either disconnection or a healthy data path, so the status reporting should be corrected before merging. Document when samples become stale as well.

Full details: Linked Issues check

Explanation

Issue [#1319] requires machine-readable freshness with documented clock semantics and a documented timeout. The implementation stores internal freshness timing and maps it to CONNECTED, DEGRADED, or UNKNOWN, but PluginDeviceStatusEntry exposes no last-sample timestamp or elapsed age. src/plugins/sharpa_avatar/README.md also does not document the 3-second timeout or the clock semantics. The implementation documents that SDK DeviceInfo.online cannot provide an independent physical-connection signal, but it does not expose separate connection and streaming fields. The independent glove entries and dongle entry are present.

Resolution

Expose per-glove last-valid-sample time or age through the health interface. Document its clock semantics and the timeout that changes health. Provide an explicit supported/unsupported or equivalent reason classification when the SDK cannot determine physical connection versus streaming, and add automated coverage for publication, timeout, recovery, and one-glove isolation.

Full details: Out of Scope Changes check

Explanation

The health implementation, example option, plugin registration, documentation, and tests support [#1319]. The .gitignore change for .local-deps/ and the AGENTS.md instruction change are repository-policy housekeeping with no demonstrated connection to Avatar health reporting.

Resolution

Remove the .gitignore and AGENTS.md changes from this pull request, or move them to a separate maintenance pull request.

Full details: Docstring Coverage

Explanation

Docstring coverage is 8.33% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 24 functions across 10 files. (9 skipped: 9 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Review comments at
@src/plugins/sharpa_avatar/core/avatar_hand_tracking_plugin.cpp:
- Around line 459-460: Update the inventory refresh in update() to build the
next inventory and online state in local arrays while enumerating with
list_device_info(), then replace m_inventory_present and m_sdk_online only after
enumeration succeeds; if enumeration throws, preserve both previously stored
arrays.
- Around line 578-584: Track freshness separately for each enabled HUMAN, RAW,
and ROBOT data path instead of using the shared `fresh_data` value. Update
`refresh_data()` and the `GloveHealthInput` construction so each status entry
receives freshness for its own category, allowing a failed RAW fetch to become
stale even while HUMAN samples continue.

Review comments at @src/plugins/sharpa_avatar/README.md:
- Around line 100-112: Update the health reporting section to state that
freshness expires after 3 seconds without a successful data fetch and is
measured using the host’s monotonic std::chrono::steady_clock, not the SDK
sample timestamp.
