Connect your WordPress / WooCommerce store to Zanderio's AI-powered Sales Agent.

== Description ==

Zanderio AI connects your Wordpress site or WooCommerce store to an AI-powered sales agent that
answers customer questions in real time using your live product and order data.

The chat widget is bundled directly inside the plugin — no external scripts are
loaded or executed at runtime.  All communication with the Zanderio service uses
your store's existing Application Password credentials over HTTPS.

Features:

* One-click activation — auto-handshake with Zanderio backend
* Application Password authentication (no manual API keys)
* WooCommerce product/order sync via webhooks
* Widget colour customisation from Settings → Zanderio
* Daily health heartbeat
* Clean uninstall — all data removed from both sides

== Installation ==

= Downloaded ZIP File Installation =

1. Go to the Zanderio AI plugin page on WordPress.org and click **Download**.
2. The plugin ZIP file will be downloaded to your device, for example:
   `zanderio-ai.1.4.0.zip`
3. Log in to your **WordPress Admin Dashboard**.
4. From the left menu, go to:
   **Plugins → Add New → Upload Plugin**
5. Click **Choose File**, select the downloaded ZIP file, and then click **Install Now**.
6. Once the plugin is installed, click **Activate Plugin**.
7. After activation, you will be redirected to `app.zanderio.ai` to authorize and connect your website with Zanderio.
8. Complete the authorization process to finish the setup.
9. Once connected, Zanderio AI will be ready to use on your WordPress website.

== External Services ==

This plugin connects your WordPress site to two **Zanderio** (`zanderio.ai`)
services over plain HTTPS REST calls.  There is no WebSocket connection — all
communication, including live streaming chat responses, uses standard HTTPS
requests.

= api.zanderio.ai (REST API — store connection) =

Used server-side by the plugin (PHP) and client-side by the chat widget (JS)
to bootstrap the widget.

**Server-side (PHP):**

* **On activation** — sends your store URL, site name, admin email, WordPress
  version, WooCommerce version, and plugin version to register the store.
* **Webhooks** — WooCommerce product and order data is pushed via webhooks so
  the AI agent can answer customer questions accurately.
* **Daily heartbeat** — a lightweight ping confirming the store is still active.
* **On deactivation / uninstall** — notifies Zanderio to disconnect the store
  and delete associated data.

**Client-side (loader.js) — widget bootstrap:**

* **`POST /v1/widget/bootstrap`** — on page load, the widget exchanges the
  plugin's public widget key for a short-lived session token and your
  appearance settings (brand color, logo, launcher animation). No personally
  identifiable visitor data is required for this step; an anonymous visitor
  id is generated locally and sent along so return visits resume the same
  conversation.

= agent.zanderio.ai (AI Service — chat) =

Used client-side by the chat widget (JS) only, authenticated with the session
token issued by the bootstrap call above.

* **`POST /v1/threads/{id}/chat`** — sends the visitor's typed messages and
  streams the AI agent's reply back over the same HTTPS connection
  (Server-Sent Events) as it's generated.
* **`GET /v1/threads/{id}/state`** — restores the visitor's prior messages
  when the widget reopens after a page reload, so conversation history isn't
  lost.

== Changelog ==

= 1.7.4 =
* Fixed the daily health heartbeat and plugin lifecycle notifications (activation/deactivation/uninstall) hitting a stale backend URL missing the API version prefix, which caused them to fail silently.

= 1.7.3 =
* Fixed the chat input not receiving keyboard focus on click on some sites, which prevented typing a message.

= 1.7.2 =
* Fixed the desktop/mobile widget position setting (e.g. "left") being ignored and always falling back to bottom-right.
* Added the "Powered by Zanderio AI" attribution footer to the chat window.

= 1.7.1 =
* Fixed booking selections (event type, location, time) briefly showing as empty message bubbles in the chat.

= 1.7.0 =
* The assistant now shows what it's doing while working — searching products, checking availability, confirming a booking — instead of a generic "thinking" indicator.

= 1.6.0 =
* Redesigned the appointment time picker into day tabs with a time-chip grid, so shoppers can scan and pick a slot faster.
* Booking now asks for any required custom questions the event type needs, right in the same form as name/email.

= 1.5.0 =
* The assistant now suggests relevant follow-up questions after answering, so shoppers can keep the conversation going with a single tap.

= 1.4.7 =
* The chat widget now goes live instantly after you activate it during setup, instead of waiting for a background sync.

= 1.4.6 =
* Added voice input — shoppers can now ask the assistant questions by speaking instead of typing, with their speech transcribed automatically. Off by default; enable it from Settings → Zanderio.
* Added proactive nudges — the assistant can now surface a contextual prompt bubble based on shopper behavior (e.g. cart activity), in addition to the existing timed welcome bubble.

= 1.4.5 =
* Confirmed compatibility with WordPress 7.0.

= 1.4.4 =
* The Settings → Zanderio page now checks WordPress.org for plugin updates every time you view it, instead of waiting for WordPress's normal update schedule (up to 12 hours).

= 1.4.3 =
* Fixed the chat widget not appearing after a successful connection — the plugin now reliably receives its widget identifier from the Zanderio service and renders the widget on the storefront.

= 1.4.2 =
* Fixed the plugin's connection handshake calling a URL missing a required path segment, which made every new install fail immediately with "Route Not Found" and silently prevented the chat widget from ever loading.

= 1.4.1 =
* Corrected External Services disclosure to accurately describe the REST-based bootstrap and chat streaming endpoints (previously referenced an unused WebSocket connection).

= 1.4.0 =
* Fixed a bug where the chat widget could silently fail to send a shopper's first message right after the page loaded, requiring a manual refresh to recover.
* Redesigned the chat header and message bubbles to match your store's brand color exactly — solid brand color on the header, launcher, and your own sent messages, with a cleaner neutral background for AI replies.
* Added a modern send button that stays muted until you start typing, then fills with your brand color — the same pattern used by today's leading messaging apps.
* Reworked the widget's expanded view into a larger centered window instead of a full-screen takeover, so shoppers keep more of the page visible behind it.
* Added an idle wiggle animation and an optional auto-open delay for the chat launcher button, plus support for showing your own store logo on the launcher instead of the default icon.
* Polished launcher button padding and logo sizing for a cleaner look across screen sizes.

= 1.3.3 =
* Migrated the embed to the REST-bootstrap widget: the loader now boots from the public widget key (`window.ZanderioWidgetConfig.key`) instead of the legacy `storeId` config.
* The plugin now stores the widget key returned by the connection handshake and only renders the widget once a key is present.
* Hints the WooCommerce platform so in-widget cart adds resolve to the storefront adapter.

= 1.3.2 =
* Added cart preview sheet component for in-widget cart confirmation before adding items.
* Enhanced artifact component styling with improved product cards, carousels, notices, lists, tables, and wizards.
* Added cart preview sheet complement styles with quantity controls and product details.
* Improved artifact product card cart button interactions and disabled states.

= 1.3.1 =
* Fixed confirmation cards not displaying description text or action buttons — booking confirmations and cart flows now render correctly.
* Fixed wizard step progress not showing step descriptions.
* Improved SSE stream version validation to handle both numeric and string version numbers from backend.
* Consolidated form field schema for improved type safety across all widget surfaces.

= 1.3.0 =
* Fixed add-to-cart button not appearing for product recommendations — products now render through the full WooCommerce ProductCard / ProductCarousel regardless of whether they arrive via the new or legacy pipeline.
* Upgraded WordPress widget to the full 10-kind artifact taxonomy (card, select, confirm, notice, feedback, list, table, wizard, text, form), matching the general CDN widget and client-side playground exactly.
* New artifact kinds (booking confirmation flows, datetime slot pickers, quick-reply chips, data tables, multi-step wizard progress, inline forms, notices) now render correctly.
* Removed all legacy message-type dispatching — all AI responses flow through the unified artifact pipeline; product normalization happens once in the message hook before rendering.
* Added searching_calendar skeleton loading state to match the general widget.
* Removed dependency on the separate FeedbackButtons component; feedback is now handled inline via the feedback artifact kind.

= 1.2.5 =
* Restored product browsing to a clean arrow-based carousel with minimal store-themed previous and next controls.
* Refined product-card actions so direct WooCommerce adds use a compact cart icon button and choose-options flows show a disabled in-button loader before navigation.
* Updated the product loading state to match the restored arrow-based carousel layout.
* Improved chat refresh recovery by restoring the latest visitor conversation when the persisted conversation ID is missing or stale.

= 1.2.4 =
* Replaced the arrow-based product carousel with a gesture-first horizontal swipe rail for browsing product results inside the chat widget.
* Reworked the loading state into full-card skeleton placeholders that match the live product rail layout.
* Reduced the product-card footprint and improved CTA visibility so key actions stay visible inside the widget viewport.
* Prevented unresolved multi-variant WooCommerce products from attempting broken AJAX cart adds by routing shoppers to the product page to choose options first.

= 1.2.3 =
* Added a product-card cart confirmation flow for WooCommerce storefronts, including an in-widget bottom-sheet preview before the item is added to cart.
* Added quantity controls and clearer product, variant, and pricing details inside the cart confirmation sheet.
* Limited the product-card cart flow to WooCommerce and WordPress storefronts instead of attempting unsupported storefront cart mutations.
* Improved WordPress store relinking so plugin installs can attach cleanly to an already-connected Zanderio store during reconnect and portal-first install flows.

= 1.2.2 =
* Fixed a small streaming-cursor rendering issue that could show an empty message bubble before streamed text arrived.

= 1.2.1 =
* Refreshed the chat widget design with improved spacing, contrast-aware accent colors, a pill-style composer, and smoother message-area behavior.
* Improved the in-chat product experience with richer product cards, better variant summaries, swatches, pricing display, and stock-state feedback.
* Added storefront cart actions for WooCommerce with lightweight success and failure toast feedback.
* Improved message rendering with better action button handling, safer external link normalization, and a compact expandable thinking-status pill.
* Added storeId-aware widget bootstrap support in the WordPress plugin.
* Persist the remote store identity from install, reconnect, and authenticated health-check responses.
* Connected stores now self-heal a missing local storeId from the settings page before rendering widget config.
* Inject `storeId` into `window.ZanderioWidgetConfig` when known so the widget can bootstrap against the correct store.
* Clean up the persisted remote store identity on uninstall to avoid stale local metadata.
* Prepared the plugin for exact-origin widget hardening rollout while keeping the current compatibility path in place.

= 1.2.0 =
* Full AI streaming support — real-time SSE responses via fetch + ReadableStream.
* Thread persistence — conversation history survives page reloads.
* JWT authentication for secure AI streaming sessions.
* Thinking status indicators — contextual labels while the AI processes.
* Conversation lifecycle — end states, "Start New Chat" button.
* Proactive engagement — configurable bubble to encourage visitors to chat.
* Feedback buttons — thumbs up/down on AI responses.
* Suggestion chips — quick-reply options from the AI.
* Error handling — friendly messages for 401/403/429/5xx responses.
* Streaming cursor animation and error message styling.
* Nested config support for updated backend schema.

= 1.1.0 =
* Widget JS is now bundled inside the plugin zip (assets/loader.js) — no
  remote script is fetched or executed at runtime.
* Script and CSS enqueued via wp_enqueue_script, wp_enqueue_style and
  wp_add_inline_style for full WordPress compatibility.
* Added widget host container with fixed-position CSS, matching the Shopify
  theme extension exactly.
* Added ZanderioWidgetLoaded guard against double-initialisation.
* Added Primary Color picker to Settings → Zanderio.

= 1.0.0 =
* Initial release.
