## Abstract

This ARFC proposes a **Design Component Identity** capability: a shared
naming, namespace, and documentation discipline covering every reusable
interface element defined in the platform's design source and carried
through into its shipped implementation. It defines what a component
identity is, how its namespace is scoped, what a variant attribute must
satisfy to be named as such, when a component identity requires recorded
documentation, what a traceability relationship between a design-source
element and its shipped counterpart must guarantee, and who holds authority
to establish or change any of the above. It does not mandate a specific
tool, retroactively remediate any existing design library, or commit to a
procurement decision.

## Introduction

The platform's interface is authored twice: once as a design artifact, and
once as a shipped implementation. The two are produced on different
cadences, often by different people, and today share no required
correspondence. An interface element — a card, a badge, a status indicator —
can be defined in the design source and, independently, defined again in
the shipped implementation, with nothing recording whether the two
represent the same concept, a deliberate variation, or an accidental
duplicate.

This ARFC establishes a naming and traceability discipline that gives every
reusable interface element one identity, shared between its design source
and its implementation, together with the rules that keep that identity
meaningful over time. It is a capability for the people who design and build
the platform's interface, not for its instructors, students, or API
integrators — but per the scope note above, it is being carried through the
full ARFC review lifecycle by explicit operator direction.

## Motivation

### Current State

- Interface elements are authored independently in the design source and in
  the shipped implementation, with no required naming correspondence between
  the two.
- A design element's points of variation — the specific ways one instance
  differs from another instance of "the same" element — are frequently left
  unnamed or carry a default, non-descriptive label, so a reviewer cannot
  tell what a variation represents without inspecting the design source
  directly.
- A component's name is not required to be accompanied by any statement of
  its intent. When a name is not self-explanatory — an abbreviation, a
  domain-specific shorthand, or a term borrowed from a different context —
  nothing records what it means for a future reader.
- Two interface elements that are visually and functionally equivalent can
  be authored independently, under different names, by different areas of
  ownership, with no mechanism to detect the duplication after the fact —
  nor to confirm, when two similarly-named elements turn out to serve
  different purposes, that the difference was intentional rather than
  accidental.

### Missing Capabilities

- There is no stable identity that both the design source and the shipped
  implementation can refer to for "the same" interface element.
- There is no rule for how narrowly or broadly an identity's namespace
  should be scoped, so each area of ownership invents its own convention
  independently, and namespace depth is not tied to any consistent
  principle.
- There is no requirement that a named variation of a component correspond
  to a real, evidenced difference in behavior or content, rather than an
  arbitrary or default label.
- There is no recorded authority for who may establish a new component
  identity versus reuse an existing one, so preventing duplication is not
  anyone's responsibility.

### Design Goals

1. Give every reusable interface element one stable identity, shared between
   its design source and its shipped implementation.
2. Scope an identity's namespace to its actual ownership and reuse boundary,
   rather than a fixed depth applied uniformly regardless of need.
3. Require that a named variation of a component correspond to a verifiable
   difference, and that its name describe that difference rather than serve
   as a placeholder.
4. Require a recorded statement of intent for any component identity whose
   meaning is not self-evident from its name alone.
5. Establish a traceability relationship such that a shipped implementation
   can be resolved back to its design-source identity, or be explicitly
   marked as not design-sourced.
6. Establish who holds authority to define, rename, or reorganize a
   component identity, and how a conflicting claim between two areas of
   ownership is resolved.

## Specification

### Core Principles

- **One identity, two representations.** A component identity is a single,
  stable name that both the design source and the shipped implementation
  resolve to. The two representations may differ in medium, but must agree
  on identity.
- **Namespace follows ownership, not a fixed schema.** An identity's
  namespace reflects who actually owns and reuses the component. A shared,
  cross-cutting concept is scoped broadly; a concept specific to one area of
  the platform is scoped to that area. Namespace depth grows only when there
  is enough real density beneath it to justify organizing further — never by
  default.
- **A name must be legible on its own.** The final, most specific segment of
  a component identity must identify what kind of element it is without
  requiring its surrounding namespace for context.
- **Containment implies inheritance.** A component that exists only in
  relation to a containing component takes that container's identity as its
  own prefix, rather than being assigned an independent identity in the same
  namespace.
- **A variation must be a real variation.** A named point of variation on a
  component (its "variant attribute") must correspond to a distinction that
  actually exists in the component's behavior or content. A distinction
  that cannot be evidenced is not given a name — the component instead
  carries open, undifferentiated content.
- **Silence is not documentation.** A component identity whose meaning is
  not self-evident requires a recorded statement of what it represents.
  Absence of documentation is never treated as evidence that none was
  needed.

### Primary Objects

**Component Identity** — The stable name of one reusable interface element,
shared by its design source and its shipped implementation. An identity is
structured as an ordered sequence of segments: a namespace (see below)
followed by a final segment identifying the element's kind. Two elements
that are functionally and visually equivalent share one identity; two
elements that are deliberately distinct are given distinct identities, never
disambiguated by context alone.

**Namespace** — The portion of a component identity that scopes its
ownership and reuse boundary. A namespace may be shared across the entire
platform (for concepts with no single owning area), or scoped to a
particular area of the platform's interface. A namespace gains additional
levels only when an existing level has accumulated enough distinct
components to make further organization useful; it is never pre-emptively
subdivided.

**Variant Attribute** — A named dimension along which instances that share
one component identity differ from one another. A variant attribute's name
must describe the actual distinction it represents (for example, a
component's stage in a review process, or its visual size), rather than
being an unnamed placeholder. A component whose apparent "variations" are
really open-ended, arbitrary content is not given a variant attribute for
that content — the content is left undifferentiated.

**Component Documentation** — A recorded statement of what a component
identity represents, required whenever the identity's name would not be
self-evident to a reader unfamiliar with the specific feature it belongs to
(for example, a domain-specific abbreviation). Documentation states what the
component is for, and — where relevant — whether the content it displays is
fixed or stands in for content that varies at runtime.

**Traceability Relationship** — The declared relationship between a
component identity's design-source representation and its shipped
implementation. A component may exist in the design source only, in the
implementation only (explicitly, not incidentally), or in both — in which
case the relationship is *Traced*: both representations exist and agree on
identity.

A representation counts toward this relationship only once it is in its
authoritative, generally-visible form. A design-source or implementation
representation that exists only in a personal or otherwise unpublished
draft state does not yet satisfy Design-Sourced or Implemented — those
states require the representation to be the one other people and other
tooling would actually see.

For example, a course-summary card and the individual insight entries it
contains are declared as related component identities, with the summary
card containing instances of the entry. When both a design-source and an
implementation representation exist for each and agree on identity, the
pair is Traced. If a summary card is later found in the shipped
implementation with no declared design-source counterpart, it is flagged
Divergent until the naming authority confirms whether it is a legitimate
implementation-only component or an undeclared duplicate of something
already defined.

**Naming Authority** — The role responsible for establishing, renaming, or
reorganizing a component identity or namespace, and for resolving a
conflict when two areas of ownership independently claim to represent the
same concept.

### Lifecycle

A component identity's traceability progresses through the following
states:

```mermaid
stateDiagram-v2
    [*] --> Proposed
    Proposed --> Adopted: naming authority accepts
    Proposed --> Refused: collides with an existing identity for a different concept
    Refused --> Proposed: resubmitted under a disambiguated name
    Adopted --> DesignSourced: representation added to the design source
    Adopted --> Implemented: representation added to the shipped implementation
    DesignSourced --> Traced: implementation representation added
    Implemented --> Traced: design-source representation added
    Traced --> Divergent: an independently-authored duplicate identity is discovered
    Divergent --> Reconciled: naming authority merges the duplicate, or confirms both are deliberately distinct
    Reconciled --> Traced
    Traced --> Deprecated: superseded by a successor identity
    Deprecated --> [*]
```

The relationships among the primary objects are:

```

### Authorization

A designated naming authority may adopt, rename, or reorganize a component
identity or namespace. A contributor proposing a new identity is expected to
check whether an existing adopted identity already represents the same
concept before proposing a new one; when uncertain, the proposal goes to the
naming authority for a reuse-or-new determination rather than being decided
unilaterally by the proposer. When two independently-authored elements are
found to represent the same concept under different identities, the naming
authority — not either original author acting alone — decides whether they
are merged under one identity or confirmed as deliberately distinct, and
records the reasoning either way.

An area of ownership may propose an identity within its own namespace
without escalation. It may not unilaterally establish an identity in the
shared namespace, and may not use its own namespace for a concept that is
genuinely cross-cutting — such a proposal is redirected to the shared
namespace and the naming authority.

### Configuration

Each area of ownership may configure the internal subdivision of its own
namespace — how finely to organize the components it owns — subject to the
namespace principle above (subdivide only where density justifies it). No
area of ownership may configure a namespace boundary outside its own scope,
and the shared namespace's structure is configured only by the naming
authority.

### Error and Edge-Case Behavior

- A proposed identity that collides with an existing adopted identity for a
  **different** concept is refused; the proposer is directed to choose a
  disambiguating name rather than the collision being silently accepted.
- A variant attribute proposed without an evidenced, real distinction behind
  it is not adopted as a variant attribute; the proposer either demonstrates
  the distinction or withdraws it in favor of undifferentiated content.
- A component identity requiring documentation under the rule above is not
  adopted until that documentation is recorded — this is a condition of
  adoption, not a follow-up task that can be deferred indefinitely.
- A component discovered to exist in the shipped implementation with no
  design-source representation, and no explicit record that it is
  intentionally implementation-only, is treated as *Divergent* and routed to
  the naming authority the same as a duplicate would be.

### Version 1 Scope

**Included:**

- The definition of a component identity, its namespace-scoping principle,
  the requirement that its final segment be self-descriptive, and the
  containment-inheritance rule.
- The variant-attribute naming discipline, requiring an evidenced,
  real distinction behind any named variation.
- The component-documentation requirement for identities whose meaning is
  not self-evident.
- The traceability relationship and its lifecycle, including divergence
  detection and resolution.
- The naming authority role, its scope of authority, and the conflict
  resolution process.

**Deliberately excluded:**

- Mandating any specific design tool, or any specific mechanism for
  automatically enforcing or verifying traceability.
- Retroactively remediating any existing design library or implementation
  to conform to this capability; V1 applies to identities proposed going
  forward.
- Any procurement, licensing, or plan-tier decision that a future
  enforcement mechanism might require.
- Continuous or automated verification tooling — a future ARFC or
  implementation effort may propose this once the underlying discipline is
  in place.
- Internal code organization, file layout, or design-tool folder structure —
  these are implementation decisions made in service of the identities this
  ARFC defines, not part of the capability itself.

## Security Considerations

This capability governs an internal design/engineering artifact and
introduces no change to the ĀYŌDÈ platform's authentication, authorization,
or end-user-facing privilege model. The naming authority is a governance
role over design and implementation artifacts, not a runtime system
privilege, and its actions are not exposed through the platform API.

Because component identities and their documentation may be visible broadly
across design and engineering tooling, documentation should be scoped to
what is appropriate for that visibility — it is not a substitute for, and
should not be used to record, security-sensitive rationale or unreleased
feature details beyond what the design tool's own audience is expected to
see.

## Backward Compatibility

Adoption of this capability does not retroactively rename, reorganize, or
otherwise change any existing design-source or implementation element.
Version 1 applies to component identities proposed from adoption forward; a
decision to remediate the existing design library against this discipline
is a separate, explicitly excluded, follow-on effort.

This capability has no effect on any existing developer- or
end-user-visible platform behavior, API endpoint, or schema — it governs
the internal design-to-implementation process only.
