finding(types/plugin-chatbot): six `ChatbotSchema` keys are declared and read by no registration — `loading`, `showAvatars`, `userAvatar`, `assistantAvatar`, `markdown`, `height`

[os-sam]

Measured by the domain:ui dev seat while giving the chatbot-enhanced and chatbot-floating registrations their own authoring-face types (objectui#7655, branch claude/issue-7655-chatbot-registration-authoring-types). Filed unassigned, ungraded. Not addressed there: that card declares faces and retires nothing.

The fact

ChatbotSchema (packages/types/src/complex.ts) declares six members that none of the three plugin-chatbot registrations reads off schema. Read-site census on origin/main at 6eebc54b6, one schema.KEY count per ComponentRegistry.register(...) body in packages/plugin-chatbot/src/renderer.tsx (chatbot / chatbot-enhanced / chatbot-floating):

key	declared type	reads
loading	boolean	0 / 0 / 0
showAvatars	boolean	0 / 0 / 0
userAvatar	string	0 / 0 / 0
assistantAvatar	string	0 / 0 / 0
markdown	boolean	0 / 0 / 0
height	string or number	0 / 0 / 0

Whole-package word-boundary census, tests excluded: userAvatar and assistantAvatar have zero hits anywhere in packages/plugin-chatbot/src; showAvatars (7 hits) and markdown (5) exist only as ChatbotEnhanced component props that no registration forwards; loading (3) and height (13) are unrelated identifiers (an i18n key, the floating panel's pixel-height prop). None of the six is in the chatbot registration's designer inputs or defaultProps either, so they are reachable from TypeScript and JSON only. All six ARE mirrored on the Zod twin, so a chatbot node authoring them parses and type-checks, and the value goes nowhere.

A seventh, processVisibility, is declared on ChatbotSchema but read only by the chatbot-enhanced registration (0 / 1 / 0); on the chatbot node it has the same declared-but-unread shape. objectui#7655 declares it on ChatbotEnhancedSchema (where it is read) and leaves the ChatbotSchema member exactly as it was.

Lit controls on the same instrument: placeholder reads 1 / 1 / 1, floatingConfig 0 / 0 / 1, so the zeros are readings.

Why it is worth a card

The published type teaches six knobs that do nothing: an author (or an AI author reading the .d.ts) writes showAvatars: true or height: 400 on a chatbot node, gets no error on either face, and sees no change. It is the ADR-0049 enforce-or-remove question, one decision per key, in the shape objectui#7654 took for triggerIcon — with the difference that all six have a Zod arm, so both halves of this package's tombstone convention (?: never on the declaration plus retirementTombstone() on the twin) are available here.

Not a duplicate

Dedup ran against the repo-scoped open-issue list via REST (381 open issues, PRs excluded) with a lit positive control — chatbot-floating returns objectui#7655 and objectui#7654 — so these zeros are readings: showAvatars 0 hits; a body naming ChatbotSchema together with userAvatar, assistantAvatar, showAvatars or loading 0 hits. objectui#7295 (per-message avatar / avatarFallback on ChatMessage) is the adjacent message-level key, not these node-level ones.

Suggested route

ADR-0049 enforce-or-remove per key, in this package's tombstone shape on both faces. Enforce is unlikely to be the answer for any of the six: ChatbotEnhanced does carry a showAvatars prop, but the chatbot registration renders the plain Chatbot component, which has no such prop to forward to.

⚠️ One tension inside the same report, to resolve by measurement before this card is dispatched

This card's census lists userAvatar and assistantAvatar among the six keys read by no registration, and adds that both "have zero hits anywhere in the plugin".

The same dev report also carries an observation — not filed as a card — that the chatbot-floating registration reads showTimestamp and the four avatar keys but offers no designer input for them.

Those two statements cannot both be right about the same keys. Either:

• the "four avatar keys" of the observation are a different key set from userAvatar / assistantAvatar (different names on the floating face), in which case this card's list stands and the observation is about other keys; or
• the avatar keys are read after all, in which case this card's list is two keys too long and the ADR-0049 disposition changes for exactly those two.

⛔ Do not open this card by acting on either statement. Re-measure the per-registration read census first, per key, with a lit control — the same instrument shape the original census used (splitting renderer.tsx at the three ComponentRegistry.register calls). The answer decides how many keys this card is actually about.

Flagged rather than resolved because it is a measurement question and this seat has a standing rule against ruling from a report's prose instead of the tree.

On the observation itself

The dev's own judgement — that no rule requires input/read parity, because every registration's inputs list is a curated subset (none offers headers / requestBody / onError) — is sound, and no card is owed for the missing designer inputs on that ground alone. ⛔ It is not filed, deliberately. If the census above shows those keys ARE read, the interesting question is still not the missing input; it is whether this card's list shrinks.

The tension is resolved by measurement — both statements were true of disjoint key sets, and one key on this list is live through a channel the census cannot see

Re-measured by the domain:ui dev seat during the remediation of objectui#7655 (PR #7705), on origin/main at 8ad218d58 and on the PR head, after the contract review of that PR (comment 5550439212 there) reached the same readings independently.

The two statements

instrument	userAvatar	assistantAvatar	userAvatarUrl	userAvatarFallback	assistantAvatarUrl	assistantAvatarFallback
word-boundary hits, packages/plugin-chatbot/src, tests excluded	0	0	18	20	25	25
schema.KEY reads per registration (chatbot / chatbot-enhanced / chatbot-floating)	0 / 0 / 0	0 / 0 / 0	1 / 1 / 1	1 / 1 / 1	1 / 1 / 1	1 / 1 / 1

Lit controls on the same instrument: placeholder 1 / 1 / 1, floatingConfig 0 / 0 / 1, processVisibility 0 / 1 / 0.

So: the "four avatar keys the floating registration reads" in the dev report were userAvatarUrl / userAvatarFallback / assistantAvatarUrl / assistantAvatarFallback — read by all three registrations, not floating alone, and already on every face via ChatbotSharedKey. userAvatar and assistantAvatar really are 0 everywhere. This card's list stands at the named-read instrument, and the disposition for those two keys does not change.

But showAvatars is live on chatbot-floating — through the raw spread, not a named read

The chatbot-floating registration ends its FloatingChatbot element with a raw {...props} spread, LAST (its two siblings spread toDomProps(props) FIRST), and SchemaRenderer forwards every authored key as a prop. Rendered through the real host with a lit/dark pair: a chatbot-floating node authoring showAvatars: true renders the per-message avatar element (1; 0 without the key); the same key on chatbot-enhanced renders none (0 / 0 — the whitelist drops it, and no registration forwards it by name). Mechanism pinned on the whitelist: toDomProps({ showAvatars: true, className: 'x' }) keeps className and drops showAvatars.

⇒ This card's "read by no registration / no registration forwards" is false for showAvatars on chatbot-floating, by that channel. It stays true for the other five: loading, userAvatar, assistantAvatar, markdown, height are not ChatbotEnhancedProps members at all (markdown exists there only as enableMarkdown), so the spread has nothing to land them on — not probed through the host, stated from the props interface. The channel itself (three live keys, the authored messages seed overriding the runtime messages, node keys leaking as DOM attributes) is carded as objectui#7708 for a fence-vs-declare ruling; how that ruling goes decides whether showAvatars here is a "dark key to retire" or "a key the fence turns dark" — the same tombstone either way, but the changeset sentence differs.

Nothing on this card was acted on; the observation about missing designer inputs stands as the seat left it. Dev seat, session session_01KbJQ1y1J12nZxYzFWhP8Q3.
