A claimed slash command consumed only the text half of the composer submission: /goal with reference images executed, cleared the draft, and silently stranded the images in the rail. Model-visible attachment intent had no route through the command plane. The submission envelope is now modeled end to end. CommandDefinition input.images declares acceptance; the declaration rides the descriptor to every client, onto the minted CommandClaim, and into the input machine's claim snapshot. commands.execute carries the submission's base64 images and enforces the declaration in the executor: non-declaring commands, a missing attachment store, and exceeded batch limits settle as logged error results before the handler runs. Admission reuses the attachment package's new admitEncodedImages, extracted from api-proxy's prompt path so both wire endpoints share one limits/validation/commit sequence. Producers own model visibility: /goal submits one user followup (image blocks + a fixed reference line) after a successful create/edit so goal rounds read the images from session history; /plan folds them into its steered message. Grammar misfits (/goal pause, bare /plan, /plan off) return direct errors and the composer keeps the images. On the client, enter adjudication carries a SubmitEnvelope and every command route that cannot consume images throws a localized refusal that renders as one composer notice with draft and images retained; the claimed pre-gate applies the same copy. An accepting claim serializes the draft images, forwards them to commands.execute, and clears plus releases them only on a success outcome. The assembled web test roster gains the ui-input-trigger and ui-commands plugins, mirroring the shipped composition, so slash submissions exercise the command plane; a new keyless snapshot pins the refusal banner and the accepting /goal flow over the built client graph.

Input trigger pipeline plugin: `/` and `@` detection under the caret (word-boundary + guard-tier rules), the grouped candidate menu, and pick routing to registered sources. `ctx.inputTriggers` owns the source roster and resolves one `InputTriggerController` per session scope (`sessionOf`); the conversation wiring layer drives `track`/`arbitrate`/`onSpace`/`adjudicate` on the controller. The same controller exposes `toggleSource` for a chrome launcher to open exactly one registered source over a synthetic selection span; the resulting candidates still use the ordinary menu, keyboard arbitration, pick callback, and scoped input mutations. Sources receive a `ClientSessionContext` projection per call — sessions are always agent-backed, so the projection is the session identity alone. A source is warmed in every session controller it can reach: the roster present at scope birth warms during controller construction, and a source registered later is warmed into every live controller by the registration itself. Sources whose `lexicon` roll changes after warm implement `subscribeLexicon(session, listener)`; the controller re-polls on each notification and publishes the aggregation through its `lexicon` snapshot store. The pipeline is command-agnostic: space/enter adjudication polls the optional `matchSpace`/`matchEnter` hooks in registration order and the first non-undefined answer wins. Enter adjudication also carries a `SubmitEnvelope` (the composer's image-attachment count) so a source can refuse a submission it cannot consume whole; a `CommandClaim` declares `images: true` when its command accepts composer images, and its `submit` then receives the serialized payloads as a third argument.

Layering: `src/core/` is the pure core — `detectTrigger`, `menuReduce`/`seedGroups`/`MENU_CLOSED`, `exactMatch`, zero React/DOM/cordis; `src/client/service.ts` is the shell wiring the core to the menu snapshot store, the per-hit candidate fetch (generation-gated, `AbortSignal`-superseded, failed sources drop silently with a console record), and the three pick paths. `src/types.ts` and the two `contract.ts` files are the frozen cross-package contract; changes require main-thread arbitration.

MenuView renders the menu store into the `conversation.input.overlay` slot (list kind, session scope) and renders null while closed. Typed triggers seed every source registered for that trigger; a programmatic launcher seeds only its requested source and publishes the source name through the controller's `launcher` snapshot store until the menu closes or typed tracking resumes. Groups sort by the optional `InputTriggerSource.order` (lower first, default 0, ties keep registration order) under title rows localized through the `inputTriggers.menu` locale namespace (an unknown source shows its raw name); the list height clamps to the space above the composer, and a pointer down outside both the menu and the surrounding composer card dismisses it. The slot is owned by ui-conversation's composer entry (anchor, children declaration, lifecycle); its SlotMap type merge lives in this package's `src/client/slots.ts` because the dependency direction (ui-conversation → ui-input-trigger) admits no reverse type import. Combobox pattern: focus stays in the textarea, rows pick on mousedown, the highlight rides `aria-activedescendant`.

The `/client` exports are the plugin body (`apply`/`inject`), `InputTriggerService`, `MenuViewInjected`, and the contract types. MenuView itself is internal — the slot registration closes over it.

## Model Experience
|
|
|
|
None, as the trigger pipeline is browser presentation only — picks produce `CommandClaim`/`ReferenceInsert` data whose model-visible consequences (host command execution; inserted reference text riding an ordinary prompt) are owned by the consuming host and input-machine packages.

#### KV Cache effect
|
|
|
|
None; this package neither assembles nor sends a provider request.

## Known Limitations and Deferred Work
|
|
|
|
- **Global source layer only** — session-scope source registration (per-session shadowing, ScopedLayers-alike) is designed but not enabled; the ledger tracks the trigger condition (a real per-session source need).
|
|
- **`InputTriggerCandidate.icon` renders as text** — MenuView drops the string into the icon slot verbatim; wiring to the design-system icon enum (iconFile five-variant family) lands when that enum ships.
|
|
- **Overlay SlotMap merge home is split from slot ownership** — the sole `conversation.input.overlay` merge lives here, while ui-conversation owns its anchor, children declaration, and lifecycle because the dependency direction is ui-conversation → ui-input-trigger.
