<oelt-text-entry>

A single-line free-response question. The learner types into a native <input>; on submit the component grades against an author-supplied answer — normalized text (with |-separated alternatives) or a number with absolute tolerance — and reports one result. Interaction type: fill-in (text) or numeric.

Attributes

Attribute	Description
`id`	Required. Interaction id.
`mode`	`text` (default) or `numeric`.
`answer`	Accepted answer(s). Text: `
`tolerance`	(numeric) Absolute tolerance — passed if `
`case-sensitive`	(text) Match case exactly; default is case-insensitive.
`placeholder`	Input placeholder text.
`submit-label`	Submit button label (default `Check answer`).
`retry`	Allow re-answering; re-emits on each submit.
`manual-grade`	No answer — emits `result: "completed"` for open responses.

Slots: prompt (becomes the input’s <label>), correct / incorrect (feedback).

Grading

Text is normalized — trimmed, internal whitespace collapsed, lowercased unless case-sensitive — and compared against each alternative.
Numeric is parsed float-safe; non-numbers fail. Boundary values pass symmetrically (with answer="3.14" tolerance="0.01", both 3.13 and 3.15 pass).
Empty input shows “Enter an answer first.” and does not emit.

Keyboard map

Key	Action
`Tab` / `Shift+Tab`	Move between the input and submit button.
`Enter`	Submit (from the input or the button).

The prompt is a native <label for> bound to the input.
Numeric mode uses inputmode="decimal" for a numeric soft keyboard without the locale pitfalls of type="number".
On submit, focus moves to an aria-live="polite" feedback region; pass/fail is text, not color.

Tracking events

Emits oelt-interaction on submit: type fill-in (text) or numeric; result passed/failed (or completed with manual-grade); score 1 or 0; response the raw input.
