`PredictionLabel`¶

Ranked prediction labels with class identity and an accessible table encoding.


Import	`from hedron import PredictionLabel`
Distribution	`hedron`
Backend activity	No
Normal render mode	`RenderMode.FRAGMENT`

Live demo¶

PredictionLabelRanked prediction labels with class identity and an accessible table encoding.

The preview is a local docs simulation (not a running Hedron server). Interactive demos show a “Simulated HTMX” trace when applicable.

Basic use¶

from hedron import PredictionLabel
component = PredictionLabel([{'class_id': 'cat', 'score': 0.9, 'calibrated': True}])

Compose under Page for full documents, or return from a fragment route for HTMX swaps.

How it works¶

Phase 0.18 model-demo presentation. Retain class identity and non-color encodings for ranked scores.

This component's core behavior is server-rendered HTML and does not require a browser runtime. The preview is ordinary semantic HTML, so keyboard, form, link, and disclosure behavior comes from the platform.

Constructor and parameters¶

PredictionLabel(scores, *, title='Predictions', threshold=None, class_=None, mark=None)

Parameter	Type	Meaning
`scores`	`Sequence[PredictionScore \| Mapping]`	Ranked class scores with optional precision/calibration.
`title`	`str`	Accessible table caption.
`threshold`	`float \| None`	Optional decision threshold shown in the caption.
`mark`	`str \| None`	Optional stable test mark (`data-hedron-mark`).

Composition and backend behavior¶

Keep PredictionLabel at the smallest semantic boundary. Fragment routes should return only the replaced region and preserve stable target IDs across success, validation, empty, loading, and error responses.

PredictionLabel is primarily presentational; keep any mutation on an explicit action or component route.

Accessibility¶

Expose an HTML table (or equivalent) so screen-reader users can read class, score, and calibration without relying on color alone.

Security¶

Escaping and SafeUrl / TrustedHtml are framework concerns; authorization and data exposure remain application code. Redact secrets before rendering.

Common mistakes¶

Do not treat PredictionLabel as ground truth; pair with PredictionFeedback for governed evaluation capture.
Do not copy docs-preview JavaScript into an application server.

Testing¶

from hedron import RenderMode, render

result = render(component, mode=RenderMode.FRAGMENT)
assert result.html
assert not result.diagnostics
