The recorder was the gap: it is FTF's own customised SDK example (a 1139-line K4A MKV writer), not a stock sample, and it lived only in one machine's build tree. Bring its source into the repo and build it as part of install. It writes K4A-format MKV — the format the rest of Ithaca reads — so it stays, and gets its libk4a from the Orbbec K4A wrapper rather than Microsoft's Azure Kinect SDK, which is set aside. build_k4a_wrapper.sh builds that wrapper; build_sdk.sh injects the recorder into the SDK examples tree and builds it there against the wrapper (it depends on the SDK's own cmake targets). Found by rpath at runtime, so no LD_LIBRARY_PATH. install.sh now builds wrapper -> SDK+recorder -> preview server, each reusing an existing build so the Nano is untouched. If the wrapper is unavailable the install still completes preview-only and says so. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# Makes sure the Orbbec K4A wrapper is built for THIS platform, and prints where

# This is the libk4a provider — Orbbec's own, NOT Microsoft's Azure Kinect SDK.

# It bundles its own OrbbecSDK internally, so it builds standalone. The recorder

# dlopens the libk4a it produces (RTLD_DEEPBIND) rather than link-time linking it,
|
|
# which is why only its build/lib path matters at runtime, not link time.

|

# Reuses an existing build (leaving a working node untouched) or clones + builds.
