No source package is shared between node repositories, so the manifest and its
type URNs are the only contract a consumer has. Declaring them makes a wiring
mistake fail at validate time with the producer and consumer URNs, instead of
at runtime.
Every payload this node sends is a raw buffer whose shape and dtype live in the
metadata rather than an Arrow struct, so the URNs name the element type:
UInt8 for image_bgr, Float32 for depth, camera_info and point_cloud, String for
camera_state. tick is UInt64, matching how dora types timer inputs.
dataflow.yml now builds the node from the checkout with path: + build:. A
git:-sourced node does not pick up an adjacent manifest, so validating the
previous form checked nothing; with path: the CLI reports "injected 6 contract
type(s)" and a deliberately mismatched annotation exits non-zero under
strict_types. The README keeps the tag: form for consumers.
The workflow needs no camera and no ZED SDK, since validation never runs the
node. Also ignores the git/ and out/ working directories dora build creates,
and drops the ignore rules for the deleted test assets.
