+> Those five symbols resolve on the public surface today. That is **not** the same as a landed delta - see [reading the status block](#reading-the-status-block). For the deltas that have actually landed, see [what has landed](#what-has-landed---shipped-srcreactcomponentschatchathooksuse-chat-inputts85).
+
+## Reading the status block
+
+RFC 29 proposes a reset of a library that **already shipped**, and it is landing piecemeal. Every page here therefore carries a status block instead of a page-wide "not implemented" banner, because a page-wide banner is a claim no machine can check - and it went stale the moment [#3277](https://github.com/veryfront/veryfront-code/pull/3277) shipped the prop-getter surface and made `mergeProps` public.
+
+Read a status block like this:
+
+- **Exported from `veryfront/chat` today** - these symbols resolve on the real public surface (barrel exports plus compound sub-parts). **This does not mean the page's delta for them has landed.** `ChatInput.Submit` ships; the RFC's reshape of it does not.
+- **Not exported today** - these symbols genuinely do not exist. `deno task lint:rfc-status` fails if any of them starts shipping without this list being updated.
+- **Not in `src/` today** - the same guarantee for props and hook members, which are not exports (`submitMode`, `getDropTargetProps`).
+
+The **Import** block on each page shows the shape this RFC _proposes_, not today's barrel - so where the two differ, the status block wins. The most common difference: "every sub-part is also a flat named export" is a proposal on every page except [`ChatInput`](./components/chat-input.md#chatinput-flat-sub-part-exports---new---shipped-srcchatindexts250), where it has actually landed (`src/chat/index.ts:250`).
+
+What actually landed is marked **per delta**, on the delta's own heading:
+
+- `` `shipped` (src/path/to/file.ts:42) `` - the delta landed as specified, with the source it landed in.
+- `` `partly shipped` (src/path/to/file.ts:42) `` - part of it landed; the section says which part, and what is still proposed.
+- no status badge - still proposed. The `kept` / `changed` / `new` / `removed` badge describes the proposal, not the runtime.
+
+Every anchor is checked: the file must exist and the line must be in it. So must both symbol lists. The check runs in the lint chain, which is what stops this corpus drifting again.
+
+### What has landed - `shipped` (src/react/components/chat/chat/hooks/use-chat-input.ts:85)
+
+The complete set, as of `main`, and checked one delta at a time: every row links the delta's own heading, and `deno task lint:rfc-status` pairs each row with that badge. It fails if a badge has no row, if a row's anchor names no badge, if a row links a page without naming a delta, or if two rows claim the same delta. Pairing by page instead of by delta would let one badge cover a page's whole column - which is how the `ChatInput` flat sub-part exports row sat here unbadged.

 `BranchPicker` **is** `Message.BranchPicker` - one implementation, re-exported under a standalone name. It is a thin surface over the `getBranches` / `switchBranch` capabilities that **already exist on `useChat`**, via `useMessageBranches`. Today the wiring is split: a presentational `BranchPicker` (controlled `current`/`total`/`onPrev`/`onNext` props) plus a `Message.BranchPicker` wrapper that feeds it from message context - including the off-by-one bookkeeping (`BranchInfo.current` is 1-based, `switchBranch` takes a 0-based index, so prev/next are `switchBranch(id, current - 2)` / `switchBranch(id, current)`). The proposal hides that math inside `useMessageBranches`.

 _Changed: `submitMode`-driven, IME-guarded Enter and paste-to-attach are added, and the full native textarea surface + `asChild` open up (today only `placeholder`/`className`/`aria-label`)._
 
+**Landed** in [#3277](https://github.com/veryfront/veryfront-code/pull/3277), in **two files** - this delta has two halves, so the badge above and the [roll-up row](../README.md#what-has-landed---shipped-srcreactcomponentschatchathooksuse-chat-inputts85) each cite one of them:
+
+- **Native surface** (`src/react/components/chat/chat/composition/chat-composer.types.ts:18`, the badge's anchor): `ChatInputFieldProps` now extends `React.TextareaHTMLAttributes<HTMLTextAreaElement>` (minus the controlled trio), so the full native surface and `ref` are already the consumer's.
+- **IME guard** (`src/react/primitives/input-box.tsx:37`, the roll-up's anchor): `handleInputBoxKeyDown` checks native `isComposing`, synthetic `isComposing`, and the `keyCode === 229` fallback before Enter submits. `.Field` and `useChatInput().getFieldProps()` both route through it, so a custom textarea cannot diverge from the primitive.
+
+**Still proposed:** `submitMode`, paste-to-attach, and `asChild` on this leaf.
+
 One `<textarea>` (today: the `InputBox` primitive in multiline mode).
 
 **Layout:** in-flow block, `w-full min-w-0` (fills its container, shrinks below intrinsic width), `min-h-9`, grows vertically with content - no positioning of its own.
 
 Default content: the input value - while dictating, the live transcript replaces it (`transcript || value`). Enter submits per `submitMode`, with an IME-composition guard so CJK input never double-submits. **Paste-to-attach (proposed):** pasting files into the field adds them to the pending attachments (requires `upload` on the Root). **Always renders.** Disabled while streaming or listening (today via the `disabled` attribute; the proposal also surfaces `data-disabled`).

 `ChatSidebar` is the compound over the conversations domain. Each part renders exactly one node, `extends` the native attributes of that node, spreads `{...props}` onto it, and accepts `asChild`. It is **conversation-native**: inside a `ConversationsProvider` it needs no props - the list, active id, and select/new/delete/rename actions come from context; explicit props override (precedence: explicit prop > nearest context > default). `<ChatSidebar />` (no `.Root`) is the one-shot preset: Root + `.NewButton` + auto `.List`, wrapped in the standalone rail chrome.

+
+Shipped in [#3277](https://github.com/veryfront/veryfront-code/pull/3277). It is a real public export of `veryfront/chat`, re-exported from `src/chat/index.ts`, and it is the merge every `useChatInput` getter calls - so the getters and the exported helper cannot drift.
+
+What has _not_ landed with it: `formatSize` and `getAgentPromptSuggestionItems` are still internal, so the reference table above is the proposal, not today's barrel.

+
+The naming half of the RFC's "the word Composer is banned" decision has landed: `useChatInputContext`, `useChatInputContextOptional`, and `ChatInputContextProvider` are real exports of `veryfront/chat`, and the raw context object stays unexported as the providers rule requires.
+
+**Still proposed:** the retirement itself. `useComposerContext`, `useComposerContextOptional`, and `ComposerContextProvider` remain exported as `@deprecated` aliases pointing at the same functions, so the old names have not gone away - that removal is batched into the one breaking release. The **returned shape** is also still the old `ComposerContextValue` (`input`, `isLoading`, `onSubmit`, …), not the `UseChatInputResult` documented below; see [`useChatInput`](./use-chat-input.md) for exactly which members are real.

+
+[#3277](https://github.com/veryfront/veryfront-code/pull/3277) shipped the hook and the prop-getter surface it exists for. On `main` today `useChatInput()` returns `getFormProps`, `getFieldProps`, `getSubmitProps`, `getAttachProps`, `getVoiceProps` - each taking `(overrides?)` and merging through the public [`mergeProps`](../helpers.md), so the L2 leaves and an L3 hand-rolled composer share one merge. `getFieldProps` carries the real IME-composition guard.
+
+**Still proposed**, and every table below documents the target, not `main`:
+
+- **The options argument.** `useChatInput()` takes no options today; it reads the nearest `ChatInput` context and throws outside one. `chat` / `upload` / `voice` / `value` / `onChange` / `submitMode` are all unimplemented.
+- **The state names.** Today's result exposes `input` / `setInput` / `isLoading` / `canUseVoice` / `canAttach` / `model` / `models`; the proposed `value` / `status` / `isStreaming` renames have not happened.
+- **The actions.** `submit`, `stop`, `clear`, and `attach` are not on the result - submission still routes through the context's `onSubmit`.
+- **`getDropTargetProps`.** Not implemented; the drop zone still lives in the composer's own `useDropZone`.

+**Still proposed:** the whole options object (`turnAnchor`, `preserveScrollOnPrepend`, `observeVisibleMessages`) and the `isAutoScrolling` / `currentAnchorId` / `visibleMessageIds` state - none of those names exist in `src/`. `useStickToBottom` is also still exported rather than subsumed, so the "subsumes" claim in the heading above is a proposal too.

 `useChatSidebarItem` is the per-item context reader for the [`ChatSidebar`](../components/chat-sidebar.md) compound - exported today; throws outside a `ChatSidebar.Item`. It is what makes a swapped or extended row keep its select/rename/delete behaviour: a fully custom row composed inside `.Item` reads the same state and actions the built-in leaves (`.Title`, `.Menu`, `.Rename`, `.Delete`) consume, without re-threading props. The raw context object stays unexported; this hook is the supported way in.

 `useConversationsContext` is the supported way to read the conversation state that a surrounding `ConversationsProvider` scopes. Like all providers in the library, `ConversationsProvider` renders zero nodes, and the raw context object stays unexported - this hook is the door in. Precedence follows the library-wide rule: explicit prop > nearest context > default.

 `useConversations` owns the conversations domain. It is the L3 foundation that [`ChatSidebar`](../components/chat-sidebar.md) is built on - the hook is sufficient to rebuild the sidebar verbatim.

+### `useMessageBranches` - `new` - `shipped` (src/react/components/chat/chat/contexts/message-context.tsx:87)
+
+This hook shipped whole in [#3277](https://github.com/veryfront/veryfront-code/pull/3277): `{ index, count, previous, next }` exactly as specified, read from the nearest `Message` context, thin over the session's existing branch state. It also returns `hasPrevious` / `hasNext`, which the RFC did not name - additive, and what `BranchPicker.Previous` / `.Next` use to disable themselves.
+
+**Still proposed:** the `BranchPicker` leaves' own deltas (see [`BranchPicker`](../components/branch-picker.md)) - the hook landing did not reshape them.

+/**
+ * RFC status doc-truth lint.
+ *
+ * Sibling of `audit-chat-composability.ts`. That lint keeps Storybook
+ * composition trees honest against the real `Object.assign` parts; this one
+ * keeps the RFC reference pages honest against the real public surface.
+ *
+ * The systemic failure it exists to stop: RFC 29's 59 sub-pages each carried an
+ * identical page-level banner - "this page documents the _proposed_ API shape,
+ * not yet implemented". An RFC that lands piecemeal silently falsifies that
+ * banner: PR #3277 shipped the prop-getter surface and made `mergeProps`
+ * public, and no banner moved. A blanket claim about a whole page is not
+ * checkable, so it rots invisibly.
+ *
+ * The fix is a status ledger a machine can read. Every RFC reference page
+ * carries a status block naming, symbol by symbol, what the runtime exports
+ * today and what it does not:
+ *
+ *   > **Status: RFC 29 - partly landed.** Verified by `deno task lint:rfc-status`.
+ *   >
+ *   > - **Exported from `veryfront/chat` today:** `ChatInput`, `ChatInput.Field`
+ *   > - **Not exported today:** `formatSize`
+ *
+ * and any individual delta that has since landed is badged `shipped` with the
+ * source it landed in:
+ *
+ *   ### `ChatInput.Field` - `changed` - `shipped` (src/…/use-chat-input.ts:184)
+ *
+ * Rules, all mechanical:
+ *
+ *   1. No blanket claims. The un-checkable page-wide phrasings are banned.
+ *   2. Exactly one status block per page, in the documented grammar.
+ *   3. Every symbol claimed exported must really be on the public surface.
+ *   4. Every symbol claimed **absent must really be absent** - this is the rule
+ *      the drift needed. A page may not say "not yet implemented" about
+ *      something that ships.
+ *   5. A `shipped` badge must cite a source anchor (`path:line`) that resolves.
+ *   6. The banner's landed-ness word must agree with the page's `shipped`
+ *      badges, so the page-level summary can never drift from its deltas again.
+ *   7. The reference index's roll-up table is the complete set of landed
+ *      deltas, and must agree exactly with the badges - one row per badge,
+ *      paired by the delta's own heading anchor, not merely by page.
