Module validation 

Form-field validation driver.

Recomputes the is_valid flag on every entity carrying a Validation component and mirrors the result into PropertyStore under the valid:<lumen-id> global key.

Supported matchers:

• required: trimmed text must be non-empty; the slider value must be > 0; the toggle must be checked.
• pattern: content must contain the configured literal substring, or match a named shape when the pattern starts with shape: (see matches_pattern).
• min / max: numeric range applied to slider values and to input text when it parses as a number.

Structs

ValidationPlugin

Plugin: registers apply_validation in TickStage::Systems so validation runs after author-side tick logic has settled.

Functions

apply_validation

Walk every entity whose validation input changed this tick. Pick the most relevant content source (TextContent -> slider -> toggle), apply the rules, write the result back to Validation::is_valid, and mirror into PropertyStore[Global("valid:<id>")] when the entity has a stable LumenId.

evaluate

Pure validation function - handy for tests and any author-side script-bridge that wants to validate a value without spawning an entity. Pass the relevant slot for the entity’s kind; the other slots stay None.

matches_pattern

Apply a pattern rule to one value.
