0003 — UI Copy, Required Marker And Temporal Field Direction

• Status: ACCEPTED USER DIRECTION
• Date: 2026-08-14
• Owner: NS0-002
• Restriction delta: RD-000 / NONE

Decision

1. User-facing UI uses English labels and no subtext of any kind by default. Process scope, implementation status and unresolved-semantics disclaimers remain documentation-only and must not appear as page subtitles, helper text, cards or footers.
2. Developer/evidence/profile descriptions do not appear in ordinary Product or Compatibility surfaces.
3. Required fields use a danger-colored * or equivalent compact mark immediately after the label. The visible word Required is not used.
4. Date, Time, Datetime and Datetime Local are consolidated into one target visual family, TemporalField.
5. Appointment reuses the shared date picker and adds a status-aware TimeBlock picker.
6. CTC uses Theme H and MK uses Theme K by default. H/K share every metric and behavior; only semantic colors differ.

Allowed Secondary Text

Validation, error/recovery, safety, active status, time-block availability/capacity, accessibility and record-disambiguation text remain allowed when necessary.

Consequences

• Existing prototypes and future UI Catalog entries must remove decorative helper copy.
• Process reconstruction determines actual requiredness and temporal semantics.
• Legacy field-type names remain source evidence but do not force separate target controls.
• Theme selection remains Presentation-only configuration.
