+# Messaging UI SDK — Design
+
+**Date:** 2026-07-17
+**Status:** Approved, pending implementation plan
+
+## Problem
+
+Messaging UI is rewritten from scratch in every app that needs it. `lynkeduppro-crm`
+has a rich, working messenger — conversation list, thread view, bubbles, reactions,
+reply threading, typing, read receipts — built as 352 lines in
+`src/components/dashboard/messenger.tsx` over 371 lines in `src/lib/messenger-api.ts`.
+None of it is reusable.
+
+### Why not just use `@insignia/iios-message-web`?
+
+Because it does not solve this problem, and the CRM already rejected it.
+
+`iios-message-web` is 109 lines across 2 files. It is fully headless: its only JSX is
+the context provider element itself. It exports `MessageProvider`, `useThread`,
+`useMessages` and a `Message` type — nothing more. It ships no components, no CSS, no
+theming.
+
+It also guessed its API wrong. `useMessages.send` narrows the options bag to
+`{ contentRef? }`, while the underlying `MessageSocket.sendMessage` accepts
+`parentInteractionId`, `mentions`, and `attachment`. Threading, mentions and
+attachments are unreachable through its public API. The socket is held in a
+module-private context with no escape hatch. It has zero consumers outside the iios
+repo, and its own docs reference a `useSendMessage` hook that does not exist.
+
+The CRM consequently bypassed it and depends on `@insignia/iios-kernel-client`
+directly.
+
+**The lesson drives this design:** the headless layer is already an SDK
+(`iios-kernel-client` — sockets, threads, receipts, typing, published, consumed). A
+second headless package saves no app any work. The unsolved part is the UI.
+
+### Why tower is not a consumer
+
+Tower's messaging is a WhatsApp group ingest → moderate → forward pipeline, not chat.
+There is no `Conversation` model; `Message` is a captured group post keyed by
+`senderJid` + `sourceGroupId` with a moderation `status` enum
+(`RAW/PENDING/APPROVED/...`) — no recipient, no delivery state. "Send" is a BullMQ job
+rate-limited to 20 forwards/minute to avoid WhatsApp bans. There is no
+socket.io/websocket/SSE in the browser anywhere in the repo. Its `threads` and
+`drafts` mean different things than a chat SDK's would.
+
+Tower would pay the abstraction cost for realtime machinery it never turns on. It is
+explicitly out of scope.
+
+## Constraint: one real consumer
+
+`lynkeduppro-crm` is the only consumer. Genericity is not achievable by intent — it is
+forced by a second consumer. This design therefore ports only what is already proven
+in production and refuses to invent abstraction for imagined needs. `iios-message-web`
+is the cautionary example of the opposite approach.
+
+## Architecture
+
+One package, `@insignia/messaging-ui`, published to the existing Gitea registry
+(`https://git.lynkedup.cloud/api/packages/insignia/npm/`). React as a peer dependency.
+
+```
+@insignia/messaging-ui
+  .                  → components + provider + hooks
+  ./styles.css       → structural CSS + token defaults
+  ./adapters/kernel   → optional iios-kernel-client adapter
+  ./adapters/mock     → in-memory adapter for demos/tests
+```
+
+**The core has zero transport knowledge.** `iios-kernel-client` is reachable only via
+the optional `./adapters/kernel` subpath, so an app on a different backend never pulls
+socket code. This is the specific mistake `iios-message-web` made by welding itself to
+`MessageSocket`.
+
+This boundary is load-bearing for the actual consumer: the CRM does **not** talk to
+iios directly. It routes messaging through be-crm's data door (`crm.messenger.*`) via
+`@abe-kap/appshell-sdk`, socket-primary with a 4s REST poll fallback. An SDK that
+hardcoded `iios-kernel-client` could not be adopted by the only app that wants it.
+
+## The adapter contract
+
+Lifted from the existing `MessengerData`/`ThreadData` interfaces in
+`src/lib/messenger-api.ts`, which already survived two implementations (live + mock).
+Two implementations is the minimum real evidence that a seam is genuine rather than
+imagined. This contract was not designed for an SDK — it earned its shape.
+
+```ts
+interface MessagingAdapter {
+  listConversations(): Promise<Conversation[]>;
+  openThread(p: { participantIds: string[]; subject?: string }): Promise<{ threadId: string }>;
+  history(threadId: string): Promise<Message[]>;
+  send(threadId: string, content: string, opts?: SendOpts): Promise<Message>;
+  subscribe(threadId: string, cb: (e: MessageEvent) => void): Unsubscribe;
+  sendTyping(threadId: string): void;
+  markRead(threadId: string, messageId: string): Promise<void>;
+  react?(messageId: string, emoji: string): Promise<void>;
+  upload?(file: File): Promise<{ url: string; mime: string; name: string }>;
+  currentActorId(): string | null;
+}
+
+interface SendOpts {
+  parentInteractionId?: string;
+  attachment?: { url: string; mime: string; name: string };
+}
+```
+
+### Graceful degradation
+
+`react` and `upload` are optional. When an adapter omits them the UI hides the
+reaction picker or the attach button respectively. This is how one component set
+serves both a full CRM messenger and a stripped-down widget without a `mode` prop.
+
+### `currentActorId` fixes a live bug
+
+Today the CRM infers the current actor id by scanning for a message you sent:
+
+```ts
+// src/lib/messenger-socket.tsx — current behaviour
+const mine = socketMsgs.find((m) => m.mine && m.actorId);
+if (mine?.actorId && mine.actorId !== myActorId) setMyActorId(mine.actorId);
+```
+
+Until you have sent a message in a thread, `myActorId` is `null`. Because the REST
+poll fallback computes `mine: !!myActorId && m.actorId === myActorId`, **every message
+renders as not-yours** in that state. The root cause is that the kernel's receipt
+event carries no `threadId`, making it a global stream the CRM compensates for.
+
+Making identity an explicit adapter responsibility eliminates this class of bug rather
+than porting it. The two-tier socket/poll fallback stays in the adapter, not the SDK —
+the CRM's adapter keeps its 4s poll; a socket-only app implements `subscribe` and
+never polls.
+
+## Components
+
+Composable primitives plus one all-in-one for drop-in use:
+
+```tsx
+<MessagingProvider adapter={adapter}>
+  <Messenger onNewChat={openPicker} />        {/* all-in-one: list + thread */}
+
+  {/* ...or compose: */}
+  <ConversationList onSelect={setId} renderRow={custom} />
+  <ThreadView threadId={id} />
+  <Composer threadId={id} />
+</MessagingProvider>
+```
+
+Hooks remain exported (`useConversations`, `useThread`, `useMessages`) so a host
+wanting entirely custom UI can use the SDK headlessly. This makes `iios-message-web`'s
+use case a strict subset of this package rather than a competitor.
+
+### Explicitly out of scope
+
+- **Inbox.** Coupled to iios semantics, not chat transport. Items are projected
+  server-side by iios from domain events (`MENTION`, `NEEDS_REPLY`, `SUPPORT_UPDATE`,
+  `CRM_OWNER_INTEREST`); authz is OPA policy. A chat SDK cannot own this.
+- **People picker / directory.** Fed by `crm.messenger.directory`. "Who exists and who
+  may I message" is host and tenant territory. `<Messenger>` takes an `onNewChat`
+  callback; the host renders its own picker.
+- **Presence.** No consumer needs it.
+
+## Theming
+
+Structural CSS with token defaults, overridden by the host. No Tailwind, no CSS-in-JS,
+no build coupling — the CRM has no shadcn and near-zero Tailwind (its real styling is
+1142 lines of hand-rolled `dashboard.css` plus inline style objects), so a
+Tailwind-based SDK would force a restyle of the only consumer.
+
+```css
+:root {
+  --msg-font; --msg-radius; --msg-gap;
+  --msg-bubble-own-bg; --msg-bubble-other-bg;
+  --msg-accent; --msg-muted; --msg-surface; --msg-border;
+}
+```
+
+Every component accepts `className`; `<Messenger>` accepts a `classNames` slot map for
+per-part overrides. The CRM's existing `#6366f1 → #8b5cf6` group-avatar gradient
+becomes a token value rather than a hardcode.
+
+## Attachments
+
+The SDK renders attachments (image thumbnail, file chip, download) and calls
+`adapter.upload(file)`, passing the result into `send`. **Storage, auth, and
+size/mime limits are host concerns** — baking in an upload target would break the next
+app. The attach button is hidden when `upload` is absent.
+
+`MessageSocket.sendMessage` already accepts an `attachment` field, so this exercises
+an existing wire contract rather than inventing one. No consumer has exercised it yet;
+the CRM has no file upload anywhere today.
+
+## Data flow
+
+1. Host constructs an adapter (CRM: wrapping appshell data door + socket).
+2. `MessagingProvider` holds the adapter in context.
+3. `useConversations` calls `listConversations`; `useMessages(threadId)` calls
+   `history` then `subscribe`.
+4. `Composer` calls `send` with optimistic append; on rejection the optimistic message
+   is rolled back and the input text restored (matching current CRM behaviour).
+5. `subscribe` events reconcile against optimistic state by message id.
+
+## Error handling
+
+- Adapter method rejection surfaces via hook `error` state; components render an
+  inline error affordance, never throw.
+- Optimistic send failure restores composer text — the CRM's current behaviour, kept.
+- `subscribe` disconnect is the adapter's problem, not the SDK's. The SDK renders a
+  `connected: boolean` from the adapter as a banner (the CRM's existing "Demo mode"
+  banner generalises to this).
+
+## Validation
+
+The migration is the validation. There is no second app, so the honest bar is:
+
+1. Rewrite the CRM's `messenger.tsx` to consume the SDK; its data-door implementation
+   becomes `CrmMessagingAdapter`. **Success = identical behaviour with the 352-line
+   component deleted**, and the mock adapter preserving demo-mode fallback.
+2. Then `support.tsx`'s `MessageCenter` — currently pure `setTimeout` theatre with no
+   backend — becomes a zero-risk second surface.
+
+Two surfaces in one app is not a true second consumer. It is the best honest test
+available of the adapter boundary, and it should be understood as such. **The design
+should be revisited when a genuine second app appears** rather than treated as settled.
+
+## Testing
+
+- **Component tests against the mock adapter** — no network. This is the payoff of the
+  injected seam.
+- **`CrmMessagingAdapter` tested against the contract** independently of UI.
+- **A shared adapter conformance suite** any adapter can run, so the kernel and CRM
+  adapters are verified against one definition of correct.
+- Explicit regression test for the `currentActorId` bug: messages render as own before
+  the user has sent anything in the thread.
+
+## Open questions
+
+- Package name: `@insignia/messaging-ui` assumed, not confirmed.
+- Whether `CrmMessagingAdapter` lives in the CRM repo or ships as
+  `./adapters/crm`. Preference: the CRM repo — it depends on appshell-sdk, which the
+  SDK must not.

-// Messenger — internal team + client chat, powered by IIOS via
-// the be-crm data door (crm.messenger.*). Conversation list ⇄
-// thread view + composer, with a "new chat" people picker that
-// creates a DM (1 person) or group (2+). DM-vs-group and who-can-
-// chat are enforced server-side by IIOS/OPA; this is just UI.
-// Live messages, typing, read receipts and reactions come over the
-// IIOS socket (Shell mode); mock keeps the demo working offline.
