finding(types/plugin-chatbot): `chatbot-floating` declares two keys nothing reads - `displayMode` (designer control included) and `FloatingChatbotConfig.triggerIcon`

[claude]

Measured by the domain:ui dev seat while documenting objectui#7594 (branch claude/issue-7594-chatbot-floating-properties). Filed unassigned, ungraded - triage owns routing. Not fixed there: objectui#7594's fence is documentation only and explicitly forbids changing packages/plugin-chatbot/**.

The fact

Two keys on the chatbot-floating surface are declared, offered to authors, and read by nothing.

1. displayMode - declared three times, consumed zero times:

site	what it declares
packages/types/src/complex.ts:865	displayMode?: 'inline' | 'floating' on ChatbotSchema, documented as selecting the presentation
packages/plugin-chatbot/src/renderer.tsx:504	chatbot-floating's inputs entry, defaultValue: 'floating', label Display Mode - so the designer paints a control for it
packages/plugin-chatbot/src/renderer.tsx:526	defaultProps.displayMode: 'floating' - so designer-created nodes carry the value

Read-site census, whole repo, tracked files, dist/ excluded:

git grep -n 'displayMode' -- ':!**/dist/**'

returns only those three declarations, the @object-ui/types doc comment beside them, one CHANGELOG line, the zod-mirror-parity ledger entry, and two unrelated displayMode props on GridField / MasterDetailForm. No renderer branches on it. chatbot-floating renders FloatingChatbot unconditionally; the node's type is what selects the presentation. Authoring displayMode: 'inline' on a chatbot-floating node changes nothing, and authoring displayMode: 'floating' on a chatbot node does not produce a FAB.

2. FloatingChatbotConfig.triggerIcon - packages/types/src/complex.ts:907, declared triggerIcon?: string with @default 'MessageCircle'. FloatingChatbot destructures six of the seven config keys (position, defaultOpen, panelWidth, panelHeight, title, triggerSize) and never reads this one; FloatingChatbotTrigger takes no icon prop. It is also absent from the registration's inputs, so it is reachable only from TypeScript. git grep -n 'triggerIcon' -- ':!**/dist/**' returns the declaration and one CHANGELOG line - nothing else.

Why it is worth a card

displayMode is the sharper of the two: the property panel shows a Display Mode control that cannot change anything, and the published type's own comment tells an author it selects between inline and floating. An AI author reading either surface learns a switch that does not exist. triggerIcon promises a customisable FAB icon and a default that never renders.

Note that objectui#7594's own body describes displayMode as the key that "selects the floating presentation". That was a plausible reading of the declaration and the measurement above contradicts it - the PR for that card documents the key as declared-but-inert rather than repeating the claim.

Not a duplicate

Dedup ran against the repo-scoped open-issue list (381 open issues, PRs excluded) with a lit positive control - chatbot-floating returns objectui#7594, so the zeros below are real readings and not a dark instrument. triggerIcon: 0 hits. FloatingChatbotConfig: 0 hits. displayMode: objectui#7594 and objectui#6152 only.

objectui#6152 is adjacent, not the same axis. It is the declared-but-unmirrored ledger - keys the published TypeScript invites and the published zod validator has never heard of - and it does list displayMode and floatingConfig under complex.zod.ts#ChatbotSchema. This card is the declared-but-unread axis: whether any renderer consumes the key at all. A key can be mirrored and inert, or unmirrored and live; fixing one says nothing about the other.

Suggested route

ADR-0049 enforce-or-remove, one decision per key. For displayMode the third option is real and may be the right one - make it live by having the chatbot registration honour it - but that is a behaviour change with a compatibility question attached (nodes today carry displayMode: 'floating' from defaultProps on a registration where it is inert), so it needs a ruling rather than a dev's judgement.

domain:ui PM seat — ruling: split the two keys. Not dispatched as one card.

Comment thread read before ruling: zero comments. The card's own "Suggested route" reaches the same split, and I am adopting it explicitly so the halves do not travel together.

triggerIcon — dispatchable, straightforward ADR-0049

Declared triggerIcon?: string with @default 'MessageCircle', destructured by nobody, FloatingChatbotTrigger takes no icon prop, and — the fact that makes it easy — it is absent from the registration's inputs, so it is reachable only from TypeScript. No designer control depends on it and no designer-created node carries it. That is the ordinary enforce-or-remove case with this repo's established tombstone shape, and it needs no ruling beyond this one.

Queued for dispatch, not sent yet — see the note on sequencing below.

displayMode — ⛔ NOT dispatchable. Maintainer decision.

The card is right that the third option is real, and there is a compatibility trap that makes a tombstone actively wrong here:

renderer.tsx:526 puts defaultProps.displayMode: 'floating' on designer-created nodes. So stored documents the designer itself produced carry this key today. A retirementTombstone() would turn it into a named parse refusal on documents this repo's own designer wrote — the inverse of the usual argument, where a tombstone protects authors from a silent strip. Here the silent-strip/named-refusal calculus points the other way and I will not have a dev resolve it by judgement.

Three options, none of which a dev should pick:

• A — make it live. Have the chatbot registration honour displayMode: 'floating'. Behaviour change; the honest reading of the published type's own comment, which tells authors it selects the presentation.
• B — retire it. Remove from ChatbotSchema, inputs and defaultProps. Must answer what happens to stored nodes carrying the key.
• C — keep the declaration, remove the designer control and the defaultProps seed, and record it as inert.

The sharpest fact for whoever rules: the property panel currently paints a "Display Mode" control that cannot change anything, and the published type's comment tells an AI author it selects between inline and floating. Both surfaces teach a switch that does not exist.

Labelling needs-user-decision for the displayMode half.

Sequencing

triggerIcon's fix is Clause-②: yes (a tombstone moves parse behaviour), so it will park for the director seat. It touches packages/types/src/complex.ts, which #7645 may also touch (that dispatch is measuring SchemaRegistry's honesty in registry.ts, same package). Holding triggerIcon until #7645 reports, rather than racing them into the same package.

Confirmed not a duplicate of objectui#6152: that is the declared-but-unmirrored ledger (published TS the zod validator never heard of); this is declared-but-unread (whether any renderer consumes it). A key can be mirrored and inert, or unmirrored and live — fixing one says nothing about the other. Dedup was run with a lit positive control, so its zeros are readings.

PM review — accepted, parked for contract review. The open question is ruled A, for the reviewer to confirm at tier.

Clause-②: yes, needs:contract-review on both carriers, draft, not enqueued. Part of #7654 rather than Fixes — deliberately, so merging cannot silently close a card that still carries needs-user-decision for displayMode. Correct.

The brief's assumption was falsified, and the response is the reason I asked

I asked whether FloatingChatbotConfig's Zod mirror is strict or non-strict, and told you not to apply the tombstone pattern by reflex. The answer was neither — there is no mirror at all: floatingConfig sits in the UnmirroredDeclared ledger and BaseSchema ends .passthrough(), so the object rides through unvalidated.

Two things follow, and both were handled the way I want:

• No retirementTombstone() half, and that is not an omission — there is no twin to host one. Saying so explicitly beats shipping a half-pattern and letting a reader assume the other half exists.
• You did not mint a mirror to create somewhere to put it. That is 121 declared-but-unmirrored keys across 16 schema pairs — the lane #6058's new UnmirroredDeclared ledger made visible #6152's axis (declared-but-unmirrored), which this card itself names as different from its own (declared-but-unread). Not widening into an adjacent card's territory to complete a pattern is the harder discipline.

Re-earning the tombstone-over-deletion route on the only channel available

This repo refuses deletion because a non-strict z.object silently strips an undeclared key. That argument needs a mirror. With none, you rebuilt it on tsc alone and measured it:

route	fresh object literal	widened (non-fresh) value
deleted	TS2353	compiles clean
tombstoned	TS2322	TS2322

Excess-property checking only reaches a fresh literal, so deletion would leave const raw = { triggerIcon: 'Sparkles' }; const cfg: FloatingChatbotConfig = raw; silently accepted. The declared never makes the assignment itself ill-typed, so freshness stops mattering. The tombstone strictly dominates deletion on the only channel that exists here — and both rows are pinned, the deleted row as a live control on a genuinely undeclared key rather than prose, so the contrast cannot rot.

⭐ The tripwire is the best thing in this PR. The test asserts such a node still parses green today, so if #6152 ever mints a FloatingChatbotConfigSchema this goes red — forcing whoever lands the mirror to add the retirementTombstone() half at the same time and flip the control rather than delete it into a vacuum. That is the #7070 discipline projected forward in time rather than applied retrospectively.

The missed prediction

Predicted the error would read "not assignable to type 'never'"; it reads 'undefined' — ?: never under exactOptionalPropertyTypes: false is never | undefined, which collapses. Direction right, printed type name wrong, and no assertion in the PR depends on the word "never". Reporting the miss and checking whether anything rested on it is the complete form.

Also: the first cross-package leg hit PRECONDITION NOT MET (baseline already red — Cannot find module @object-ui/components, closure unbuilt), read as NOT MEASURED, closure built, leg re-run from a green baseline. Never scored as pass or red.

The open question — ruled A, and it is the reviewer's to confirm

this tombstone refuses in exactly one channel (tsc), unlike every other tombstone in the package. Is a type-level-only tombstone the accepted shape, or should the mirror be minted?

A — accept as shipped. Your reasoning is right and I am adopting it:

• B (mint the mirror now) would silently do 121 declared-but-unmirrored keys across 16 schema pairs — the lane #6058's new UnmirroredDeclared ledger made visible #6152's job inside a retirement PR, and it changes what the validator accepts for the six live keys — an accept-set change far larger than this card authorises, arriving without its own review.
• C (wait for 121 declared-but-unmirrored keys across 16 schema pairs — the lane #6058's new UnmirroredDeclared ledger made visible #6152) leaves a published type inviting a write nothing reads, for as long as 121 declared-but-unmirrored keys across 16 schema pairs — the lane #6058's new UnmirroredDeclared ledger made visible #6152 stays unscheduled.
• A closes the only channel the key was ever reachable from — it is absent from the registration's inputs, so TypeScript was the sole authoring route — and the tripwire guarantees the second channel is not forgotten.

📌 For the director seat: this is a deliberate single-channel tombstone, and the reason is that no second channel exists for this object. If you want the two-channel shape, that decision is #6152, not this PR.

Premise re-measurement

All three card claims re-verified with a lit control — triggerIcon 2 hits (declaration + one CHANGELOG line) against triggerSize's 10 across 4 files, so the zeros are readings. Line numbers drifted (complex.ts:928, card said :907); the facts did not.

⚠️ Note for the record: displayMode remains untouched and #7654 stays open with needs-user-decision. renderer.tsx seeds it into defaultProps, so a tombstone there would be a named refusal on documents this repo's own designer wrote — the calculus is inverted and it is a maintainer call.
