The two jobs each paid for a checkout, an apt-get update and an OpenCV shared
library install -- about twenty seconds apiece -- to run gates that together
take about a second. Merging them pays that once. The dora CLI is a static
binary pinned to DORA_VERSION, so it caches exactly.
`dora validate` matches a node manifest to a `path:` node by entrypoint. With
no manifest beside examples/source.py the root dora-node.yml was tried against
it, did not match its entrypoint, and warned -- which `strict_types: true`
turns into a non-zero exit, failing CI.
Declaring the source's output types in the new manifest rather than as
`output_types:` in dataflow.yml is also what makes them checked: an inline
annotation shadows the manifest, so the manifest would be injected but never
compared against the viewer's.
Verified with dora-cli 1.0.1: validate passes with both contracts injected, and
`CI=true SOURCE_FRAMES=30 dora run dataflow.yml --uv` runs both nodes to a
clean exit.
The repository, the Python package, the entrypoint and the manifest name all
now agree. `plot` was carried over from the upstream opencv-plot node and no
longer described anything here, so the module, the class and the environment
variables follow the node:
dora_plot/ -> dora_image_view/
dora_plot/plot.py -> dora_image_view/view.py
Plot -> View
PLOT_WIDTH/HEIGHT -> VIEW_WIDTH/HEIGHT
--plot-width/-height -> --view-width/-height
Breaking for anyone wiring `path: dora-plot` or setting PLOT_WIDTH; nothing is
tagged yet.
The example dataflow pulled opencv-video-capture and pyarrow-sender from
dora-hub, needed a webcam, and left `bbox` unwired because every bbox source
is a detector. examples/source.py emits an animated frame, the box around the
square in it, and a caption, so the dataflow exercises all three inputs with
nothing outside this checkout.
SOURCE_FRAMES bounds the run, which lets CI run the dataflow headless rather
than only validate it. Drops the dora-zed and dora-yolo wirings from the
README and trims AGENTS.md to what the code and README do not already say.

The repository is dora-plot, but the package, the entrypoint, the manifest
name and the window title were all opencv-plot. Consumers wire the node by
`path:`, so the split name was visible in every dataflow.
