Unauthenticated clients now attach a stable, browser-persisted anonymous visitor id (X-Base44-Anonymous-Id) to every request. This lets the Base44 backend support anonymous in-app agent access — grouping an anonymous visitor's conversations and enforcing ownership — without a signed-in user. - New getOrCreateAnonymousVisitorId() helper (localStorage-backed UUID, browser-only; returns null on the server so no header is sent there). - Header is attached in the shared axios request interceptor only when the client has no token; authenticated clients are identified by their token. Pairs with the platform-side anonymous in-app agent access work.

Reuse the existing persisted analytics session id (getAnalyticsSessionId, localStorage `base44_analytics_session_id`) as the X-Base44-Anonymous-Id value instead of minting a separate dedicated id. One identity per anonymous visitor across analytics + agents (enables correlation), and a single source of truth for the id. Follow-up (deferred): harden the id generator to crypto-strength and/or decouple agent identity from analytics — the current generateUuid is Math.random-based, acceptable short-term but weak for a bearer-style ownership credential. - Drop src/utils/anon-visitor.ts; axios-client uses getAnalyticsSessionId. - Rename test to anonymous-visitor-header.test.ts; assert the header equals the persisted analytics session id and is absent when authenticated.

Summary
Unauthenticated clients now attach a stable, browser-persisted anonymous visitor id (
X-Base44-Anonymous-Id) to every request, so the Base44 backend can support anonymous in-app agent access — grouping an anonymous visitor's agent conversations and enforcing ownership — without a signed-in user.What changed
getOrCreateAnonymousVisitorId()(src/utils/anon-visitor.ts): mints a UUID, persists it inlocalStorage, returns the same id across reloads. Browser-only — returnsnullon the server (SSR /createClientFromRequest), so no header is sent there.createAxiosClient(src/utils/axios-client.ts): the shared request interceptor attachesX-Base44-Anonymous-Idonly when the client has notoken. Authenticated clients keep being identified by theirBearertoken (no anon header). This covers every agent HTTP call (createConversation,addMessage,getConversation).Why here
The published-app surface uses this public SDK (
@base44/sdk), not the platform's internal SDK. Anonymous agent access can't work on published apps until the SDK sends this header — that's the gap this PR closes.Pairs with
Platform-side anonymous in-app agent access (base44-dev/apper#11814). The backend reads
X-Base44-Anonymous-Idonly when there's no authenticated app user, so sending it is a no-op for authenticated traffic.Testing
tests/unit/anon-visitor.test.ts(5 tests): mint/persist/stability, fresh id after clear, returns null without a browser, and the interceptor attaches the header only when unauthenticated.npm run build(tsc),eslint src, and the full unit suite (158 tests) all pass.
