+name: spree-checkout
+description: >
+ Implement Spree's checkout — the Order state machine (cart → address →
+ delivery → payment → confirm → complete), the Payment and Shipment sub-state
+ machines, the return flow (ReturnAuthorization → CustomerReturn →
+ Reimbursement → Refund), guest checkout, payment-step skipping for
+ credit-covered orders, and the V3 checkout API surface. Use when building or
+ customizing checkout flows, debugging state transitions, or wiring custom
+ checkout steps.
+---
+
+# Spree Checkout
+
+## Before writing code
+
+**Fetch live docs**:
+1. Fetch https://spreecommerce.org/docs/developer/core-concepts/orders for the canonical state machine.
+2. Fetch https://spreecommerce.org/docs/developer/core-concepts/payments for the Payment + PaymentSession (v5.4+) flow.
+3. Check the live `Spree::Order` source on GitHub for the `state_machine` block — transitions and callbacks change.
+4. For headless checkout, fetch the v3 Store API docs at https://spreecommerce.org/docs/api-reference.
+5. Verify any custom-step pattern against the latest examples in `spree-starter`.
+
+## Conceptual Architecture
+
+### The Order State Machine
+
+```
+cart → address → delivery → payment → confirm → complete
+ ↓
+ skip if store-credit-covered
+```
+
+Each transition validates prerequisites:
+
+| State | Prerequisites |
+|-------|---------------|
+| `cart` | One or more line items |
+| `address` | Bill + ship address present |
+| `delivery` | Shipping method selected for every shipment |
+| `payment` | At least one payment method valid for the total |
+| `confirm` | Optional review step (configurable) |
+| `complete` | All sub-states valid; transitions trigger fulfillment + emails |
+
+### Payment Sub-State
+
+`Order#payment_state` is a separate field summarizing all `Payment` rows:
+
+| Value | Meaning |
+|-------|---------|
+| `balance_due` | Outstanding amount remains |
+| `paid` | Fully paid |
+| `credit_owed` | Refund pending |
+| `failed` | All payments failed |
+| `void` | Voided |
+
+### Shipment Sub-State
+
+`Order#shipment_state` summarizes all `Shipment` rows:
+
+| Value | Meaning |
+|-------|---------|
+| `pending` | Awaiting payment / stock |
+| `ready` | Ready to ship |
+| `partial` | Some shipped |
+| `shipped` | All shipped |
+| `backorder` | Inventory shortfall |
+| `canceled` | Canceled |
+
+### Individual Shipment / Payment State Machines
+
+- **`Shipment#state`**: `pending → ready → shipped` (+ `canceled`)
+- **`Payment#state`**: `checkout → processing → pending → completed` (+ `failed`, `void`, `invalid`)
+
+### Return Flow
+
+```
+ReturnAuthorization (authorized | canceled)
+ → CustomerReturn
+ → Reimbursement (pending | reimbursed | errored)
+ → Refund (against original Payment)
+```
+
+`StoreCredit` reimbursements skip the Refund step and credit the user's balance.
+
+### Skipping the Payment Step
+
+If `order.outstanding_balance.zero?` after store-credit/gift-card application, the state machine skips `payment` and goes straight to `confirm`. Useful for free-trial / 100%-off scenarios.
+
+### Guest vs Authenticated Checkout
+
+Spree supports guest checkout by default — orders carry an `email` and `order_token` even without a `User`. The token allows a guest to revisit their order. Convert guests to users post-checkout via `Spree::Order#associate_user!`.
+
+### Custom Checkout Steps
+
+Add a custom step by inserting into the state machine via decorator:
+
+```ruby
+# app/models/spree/order_decorator.rb
+module MyApp::OrderDecorator
+ def self.prepended(base)
+ base.state_machine.before_transition to: :delivery, do: :verify_gift_message
+ end
+
+ def verify_gift_message
+ # …
+ end
+
+ Spree::Order.prepend(self)
+end
+```
+
+Custom steps are powerful but **upgrade-fragile** — Spree's state machine evolves. Prefer events or service objects when you only need to react.
+
+### Checkout via API v3 (v5.4+)
+
+Headless checkout typically:
+
+1. `POST /api/v3/store/cart` — create cart (returns `ord_…` ID + cart token)
+2. `POST /api/v3/store/cart/line_items` — add items
+3. `PUT /api/v3/store/checkout` — set addresses, shipping method, payment method
+4. `POST /api/v3/store/checkout/payment_sessions` — create a PaymentSession (Stripe/Adyen/PayPal)
+5. `POST /api/v3/store/checkout/complete` — finalize
+
+(Verify exact paths in the v3 API reference — endpoint shapes are still settling.)
+
+### Payment Sessions (v5.4+)
+
+The v5.4 `PaymentSession` abstracts the payment-provider handshake. The storefront creates a PaymentSession, the user authorizes via the gateway's hosted UI (Stripe Elements, Adyen Drop-in, PayPal Checkout), and the session is captured into a `Payment` on completion. Provider-specific.
+
+## Implementation Guidance
+
+### Reading the Current State
+
+```ruby
+order.state # one of cart/address/delivery/payment/confirm/complete
+order.payment_state # balance_due/paid/...
+order.shipment_state # pending/ready/...
+order.can_transition?(:complete) # check before triggering
+```
+
+### Triggering Transitions Programmatically
+
+```ruby
+order.next! # advance to the next state if valid
+order.complete! # force to complete if valid (typically last step)
+order.cancel! # cancel + revert inventory
+```
+
+Never call `update_attribute(:state, …)` directly — bypasses callbacks and corrupts inventory/payments.
+
+### Subscribing to Checkout Events
+
+```ruby
+class CheckoutSubscriber < Spree::Subscriber
+ subscribes_to 'order.completed'
+ on 'order.completed', :send_welcome_email
+
+ def send_welcome_email(event)
+ return if event.order.user.nil?
+ # …
+ end
+end
+```
+
+Events fire after the database commit — safe to enqueue background jobs.
+
+### Headless Checkout Patterns
+
+- **Always use httpOnly cookies for the cart/order token**, not localStorage.
+- **Confirm the cart server-side before showing the review step** — prices, tax, shipping can change between page loads.
+- **Idempotency-Key headers on `/complete`** — prevent double-charging on retry.
+- **Use Payment Sessions for v5.4+** — they handle 3DS / SCA / Apple Pay / Google Pay uniformly.
+
+### Debugging Stuck Transitions
+
+```ruby
+order.errors.full_messages
+order.valid?(state) # validate for a specific state
+order.checkout_steps # configured step list
+```
+
+### Returns Workflow
+
+```ruby
+ra = Spree::ReturnAuthorization.create!(order: order, return_items: items)
+ra.authorize!
+cr = Spree::CustomerReturn.create!(return_items: ra.return_items, stock_location: location)
+cr.fully_received?
+reimbursement = Spree::Reimbursement.create!(customer_return: cr, order: order)
+reimbursement.perform! # creates Refunds or StoreCredits
+```
+
+### Common Pitfalls
+
+- **Bypassing the state machine** by setting `state` directly → corrupts inventory and payment totals.
+- **Forgetting to recompute totals** after adjusting line items → use `Spree::OrderUpdater`.
+- **Marking a Payment `completed` manually** → use the gateway's capture flow; manual completion skips reconciliation.
+- **Treating `confirm` as required** — it's configurable (`checkout_steps` order).
+- **Headless checkout drift** — the storefront's local state can diverge from the server's `Order#state`. Re-fetch after every mutating call.
+- **Custom decorator on `state_machine`** — survives minor upgrades poorly; prefer event subscribers when possible.
+
+Always re-verify state names and transition guards against the live `Spree::Order` source for the version you target.

+# Publishing to OpenAI Codex CLI
+
+OpenAI Codex CLI shipped a first-class plugin marketplace system in **v0.128.0 (April 30, 2026)**. This repo is wired to be added as a Codex marketplace in one command.
+
+## What Codex's marketplace model looks like
+
+Per https://developers.openai.com/codex/plugins/build:
+
+- **No centralized OpenAI-hosted directory.** Anyone can publish.
+- **A "marketplace" is a Git repo** containing `.agents/plugins/marketplace.json` at its root.
+- **Users register a marketplace** with `codex plugin marketplace add owner/repo`.
+- **Plugins are bundles** with `.codex-plugin/plugin.json` + `skills/` + `agents/` + `hooks/`.
+- **Installation happens via the TUI** `/plugins` browser after a marketplace is added.
+
+This is structurally similar to Claude Code's marketplace model — which is intentional, since both use the cross-tool `.agents/` namespace.
+
+## Repo layout for Codex
+
+```
+agentic-commerce-skills-plugins/
+├── .agents/
+│ └── plugins/
+│ └── marketplace.json # Codex marketplace manifest — 15 plugins enumerated
+├── dist/codex/<plugin>/
+│ ├── .codex-plugin/
+│ │ └── plugin.json # Per-plugin manifest (name, version, interface, hooks)
+│ ├── AGENTS.md # Auto-loaded context
+│ ├── agents/<expert>.toml # Subagent definitions (bundle-source path)
+│ ├── skills/<skill>/SKILL.md # Skills (bundle-source path)
+│ ├── hooks/hooks.json # Plugin-bundled hooks (v0.128+)
+│ └── scripts/check_*.py # Hook scripts as standalone utilities
+```
+
+Note: the bundle-source paths are `agents/` and `skills/` (not `.codex/agents/` and `.agents/skills/`). Codex's runtime relocates them to their canonical install locations when the plugin is installed.
+
+## Install (end users)
+
+### Add the marketplace and install plugins
+
+```bash
+# 1. Install Codex CLI if not present
+npm install -g @openai/codex
+# or
+brew install --cask codex
+
+# 2. Register this repo as a marketplace
+codex plugin marketplace add OrcaQubits/agentic-commerce-skills-plugins
+
+# 3. Inside the Codex TUI, browse and install plugins
+codex
+/plugins
+```
+
+The TUI surfaces all 15 plugins. Pick one to install — Codex caches it under `~/.codex/plugins/cache/agentic-commerce/<plugin-name>/<version>/` and activates its skills, subagents, and hooks.
+
+### Optional flags
+
+```bash
+# Pin to a specific ref (tag, branch, or commit)
+codex plugin marketplace add OrcaQubits/agentic-commerce-skills-plugins --ref v1.0.0
+
+# Sparse-checkout (only fetch what's needed for plugin discovery)
+codex plugin marketplace add OrcaQubits/agentic-commerce-skills-plugins --sparse .agents/plugins
+```
+
+## Publishing flow (maintainer)
+
+There's no submission step for OpenAI — anyone can publish, anyone can subscribe. The repo just needs:
+
+1. `.agents/plugins/marketplace.json` at root (already present)
+2. Each plugin bundle reachable at the `source.path` listed in the marketplace.json
+3. Each plugin's `.codex-plugin/plugin.json` validates per [the manifest spec](https://developers.openai.com/codex/plugins/build)
+
+When you bump a plugin version or add a new plugin:
+
+```bash
+# 1. Update sources under <plugin>/.claude-plugin/ and skills/ as usual
+# 2. Regenerate the Codex output
+python scripts/convert.py --platform codex
+
+# 3. (Only if you added a NEW plugin) regenerate root marketplace.json
+python -c "
+import json, pathlib
+# ... see scripts/convert.py for marketplace gen logic
+"
+
+# 4. Commit + push
+git add .agents/plugins/marketplace.json dist/codex/
+git commit -m 'chore(codex): bump plugin X to vY.Y.Z'
+git push
+```
+
+Marketplaces refresh automatically on `codex plugin marketplace upgrade <name>` or on next cache miss — no tag required (unlike Gemini), but tagging a release helps users pin.
+
+## Bonus: contribute to OpenAI's curated skills catalog
+
+OpenAI maintains a separate official catalog at https://github.com/openai/skills with `.system`, `.curated`, and `.experimental` tiers. Standalone skills (without a plugin wrapper) can be submitted via PR for inclusion in the `.curated` tier. Useful as a second discovery surface — installable via Codex's built-in `$skill-installer` tool.
+
+This is independent of the marketplace flow above.
+
+## Plugin manifest reference (what our converter emits)
+
+`dist/codex/<plugin>/.codex-plugin/plugin.json` conforms to https://developers.openai.com/codex/plugins/build. Fields:
+
+| Field | Purpose |
+|-------|---------|
+| `name` | kebab-case plugin slug |
+| `version` | semver |
+| `description` | summary |
+| `license` | MIT |
+| `keywords` | array — surfaced in marketplace search |
+| `author` | `{name, email?}` — author metadata |
+| `homepage` | URL — surfaced in marketplace UI |
+| `repository` | `{type, url}` — Git source location |
+| `hooks` | path to `./hooks/hooks.json` |
+| `interface.displayName` | human-readable name |
+| `interface.shortDescription` | tile/card subtitle |
+| `interface.longDescription` | detail view body |
+| `interface.category` | filtering category |
+| `interface.websiteURL` | external link |
+| `interface.developerName` | byline |
+
+Optional fields not currently emitted: `interface.composerIcon`, `interface.logo`, `interface.screenshots`, `interface.brandColor`, `interface.privacyPolicyURL`, `interface.termsOfServiceURL`. Can be added later to enrich marketplace listings.
+
+## Troubleshooting
+
+| Symptom | Fix |
+|---------|-----|
+| `codex plugin marketplace add` fails with "marketplace.json not found" | Confirm `.agents/plugins/marketplace.json` is at repo root. |
+| Plugin shows in `/plugins` but won't install | The bundle's `source.path` doesn't resolve. Confirm `dist/codex/<plugin>/` is committed (not gitignored). |
+| Subagent not invocable after install | Check Codex version — subagent TOML format is "evolving" per docs and minor breaks are possible across versions. |
+| Hooks don't fire | Codex v0.128+ supports plugin-bundled hooks but the path-variable convention may differ from Claude's `${CLAUDE_PLUGIN_ROOT}`. Our converter copies hooks.json verbatim; scripts run as standalone utilities regardless. |
+| Want to retract a plugin | Drop its entry from `.agents/plugins/marketplace.json` and commit. |

+# Publishing to Cursor
+
+Cursor (as of 2.6, May 2026) has **three distinct publishing surfaces** for AI plugins. This repo is configured to use all three; the recommended primary path for this monorepo is the **Team Marketplace** because it supports all 15 plugins in one import without requiring Anysphere review.
+
+| Surface | Best for | Audience | Approval needed |
+|---------|----------|----------|-----------------|
+| **Team Marketplace** (Cursor 2.6) | Multi-plugin GitHub repos like this one | Teams/Enterprise plan members | None — admin imports a GitHub URL |
+| **Public Marketplace** (cursor.com/marketplace) | Single flagship plugin | Everyone | Anysphere review |
+| **cursor.directory** | Community discovery | Everyone | None — auto-detected |
+
+References:
+- Marketplace storefront: https://cursor.com/marketplace
+- Plugins overview: https://cursor.com/docs/plugins
+- Schema reference: https://cursor.com/docs/reference/plugins
+- Official plugins repo (spec + schemas): https://github.com/cursor/plugins
+- Plugin template: https://github.com/cursor/plugin-template
+- Team Marketplaces (2.6 forum post): https://forum.cursor.com/t/cursor-2-6-team-marketplaces-for-plugins/153484
+- Cursor 2.5 launch (marketplace debut): https://cursor.com/changelog/2-5
+
+## Repo layout
+
+The repo is wired for direct Cursor consumption:
+
+```
+agentic-commerce-skills-plugins/
+├── .cursor-plugin/
+│ └── marketplace.json # Team Marketplace manifest — enumerates 15 plugins
+├── dist/cursor/<plugin>/
+│ ├── .cursor-plugin/
+│ │ └── plugin.json # Per-plugin manifest (schema-validated)
+│ ├── agents/<expert>.md
+│ ├── rules/<expert>.mdc
+│ ├── skills/<skill>/SKILL.md
+│ ├── hooks/hooks.json
+│ └── scripts/check_*.py
+└── scripts/
+ └── validate-cursor.mjs # Mirror of Cursor's CI validator (ajv)
+```
+
+The root `.cursor-plugin/marketplace.json` is what Cursor's Team Marketplace import reads. The `source` field on each entry points at the converted plugin directory under `dist/cursor/`.
+
+## Path 1 — Team Marketplace (recommended for this repo)
+
+**No review, no submission form.** Admins of a Cursor Teams/Enterprise org import any GitHub repo URL.
+
+### What an admin does
+
+1. In Cursor: **Settings → Plugins → Team Marketplaces → Import**
+2. Paste `https://github.com/OrcaQubits/agentic-commerce-skills-plugins`
+3. Cursor parses the root `.cursor-plugin/marketplace.json` and surfaces all 15 plugins
+4. Admin assigns plugins to **Access Groups** (e.g., "Engineering", "Commerce-team")
+5. Members in those groups see the plugins in the Cursor Plugin browser and install with one click
+
+Teams plan = 1 marketplace per org; Enterprise = unlimited.
+
+### Updating the marketplace
+
+When you bump a plugin version or add a new plugin:
+
+```bash
+# 1. Update sources under <plugin>/.claude-plugin/ as usual
+# 2. Regenerate the Cursor output
+python scripts/convert.py --platform cursor
+
+# 3. (Only if you added a NEW plugin) regenerate root marketplace.json
+python -c "
+import json, pathlib
+src = json.load(open('.claude-plugin/marketplace.json'))
+plugins = [{'name': p['name'], 'source': f'dist/cursor/{p[\"name\"]}', 'description': p['description']} for p in src['plugins']]
+out = {'name': 'agentic-commerce', 'owner': {'name': 'Rohit Bajaj, Julekha Khatun'}, 'metadata': {'description': '...', 'version': '1.0.0'}, 'plugins': plugins}
+json.dump(out, open('.cursor-plugin/marketplace.json', 'w', encoding='utf-8', newline='\n'), indent=2, ensure_ascii=False)
+"
+
+# 4. Validate before committing
+node scripts/validate-cursor.mjs
+
+# 5. Commit and push
+git add .cursor-plugin/marketplace.json dist/cursor/
+git commit -m "chore(cursor): bump plugin X to vY.Y.Z"
+git push
+```
+
+Team Marketplaces refresh automatically — no tag required (unlike Gemini).
+
+## Path 2 — Public Cursor Marketplace
+
+Submit one plugin (e.g., the UCP flagship, matching what we did for Gemini) at **https://cursor.com/marketplace/publish**. Anysphere reviews each plugin before listing.
+
+### Submission checklist (per https://cursor.com/docs/reference/plugins)
+
+- [ ] Valid `.cursor-plugin/plugin.json` matching the JSON Schema (we validate via `node scripts/validate-cursor.mjs`)
+- [ ] Unique kebab-case `name` (pattern `^[a-z0-9]([a-z0-9.-]*[a-z0-9])?$`)
+- [ ] All paths in the manifest are relative; no `..` traversal
+- [ ] Every rule / skill / agent / command has frontmatter
+- [ ] `README.md` documents usage clearly
+- [ ] Optional `logo` is committed and referenced relatively
+- [ ] For multi-plugin: `.cursor-plugin/marketplace.json` at repo root (we have this)
+
+### Flow
+
+1. Polish the flagship plugin's README + logo
+2. Test locally by dropping it at `~/.cursor/plugins/local/<plugin-name>/` and reloading Cursor
+3. Submit via the web form at https://cursor.com/marketplace/publish OR email Cursor's plugin team at `[redacted-email]` (path documented in cursor/plugin-template)
+4. Wait for review
+
+**Don't submit PRs to https://github.com/cursor/plugins** — that repo is reserved for first-party Cursor-authored plugins (all 11 entries are by Anysphere staff).
+
+## Path 3 — cursor.directory community listing
+
+The lowest-friction discovery surface.
+
+1. Visit **https://cursor.directory/plugins/new**
+2. Paste the GitHub repo URL
+3. cursor.directory auto-detects components following the "Open Plugins" standard
+4. Listing appears in the community catalog
+
+cursor.directory is owned by the `cursor` GitHub org (https://github.com/cursor/community-plugins) but isn't gate-kept. Good for SEO and community visibility alongside whichever primary path you choose.
+
+## Local development install
+
+For a developer testing a plugin without going through any marketplace:
+
+```bash
+# Generate Cursor output
+python scripts/convert.py --platform cursor
+
+# Symlink (or copy) the plugin to Cursor's local plugins dir
+ln -s "$(pwd)/dist/cursor/spree-commerce" ~/.cursor/plugins/local/spree-commerce
+
+# Reload Cursor window
+# (Command Palette → "Developer: Reload Window")
+```
+
+## Pre-commit validation
+
+This repo ships `scripts/validate-cursor.mjs` which mirrors Cursor's CI validator (`ajv` against the official schemas):
+
+```bash
+npm install --no-save ajv ajv-formats
+node scripts/validate-cursor.mjs
+```
+
+It checks:
+- The root `.cursor-plugin/marketplace.json` validates against `marketplace.schema.json`
+- Every `dist/cursor/<plugin>/.cursor-plugin/plugin.json` validates against `plugin.schema.json`
+- Every `source` in `marketplace.json` resolves to a real `plugin.json`
+
+Run before tagging any release. Cursor's own CI runs the same checks during Team Marketplace import.
+
+## Schema notes (gotchas learned the hard way)
+
+- **`additionalProperties: false`** on the plugin schema — any unknown key (e.g., `author.url`, which was in our pre-fix output) fails validation. The converter has been patched to drop `url` and move it to top-level `homepage`.
+- **`author` object shape**: `{name, email}` only. `homepage` is a separate top-level field.
+- **Name pattern**: lowercase + digits + hyphens/periods, alphanumeric at start and end.
+- **`hooks` field**: accepts a string path (`"./hooks/hooks.json"`) or an inline object. The converter emits the path string when `hooks/hooks.json` exists.
+- **`.mdc` rule frontmatter**: only `description`, `alwaysApply`, `globs` are recognized. No `type`, `priority`, `attachAlways`, etc.
+- **MCP servers** go in a top-level `mcp.json` file (auto-discovered) OR via the `mcpServers` manifest field. Our current plugins don't ship MCP servers.
+
+## Troubleshooting
+
+| Symptom | Fix |
+|---------|-----|
+| Team Marketplace import fails with schema error | Run `node scripts/validate-cursor.mjs` to find the offending plugin. |
+| `additionalProperties NOT allowed` | The converter emitted an unknown key. Pull the latest converter from this repo or remove the key. |
+| Plugins list as "0 plugins" after import | The `source` paths in `marketplace.json` don't resolve. Confirm `dist/cursor/` is committed (not gitignored). |
+| Plugin installs but rules don't activate | Check `.mdc` frontmatter — `alwaysApply: true` for global rules, or set `globs` and `alwaysApply: false` for path-scoped. |
+| Hook script not found | The converter emits `${CURSOR_PLUGIN_ROOT}/scripts/check_*.py`. Confirm `scripts/` is committed at the plugin's root. |
+| Want to remove a plugin from the marketplace | Drop its entry from `.cursor-plugin/marketplace.json` and commit. Imported teams refresh automatically. |

+ payment-state issues.
+---
+
+# Spree Payments
+
+## Before writing code
+
+**Fetch live docs**:
+1. Fetch https://spreecommerce.org/docs/developer/core-concepts/payments for the Payment + PaymentSession model.
+2. Fetch the integration repo README — https://github.com/spree/spree_stripe / spree_adyen / spree_paypal_checkout — for current install + config.
+3. Check the gateway's own SDK docs (Stripe / Adyen / PayPal) for the latest API version.
+4. Inspect the live `Spree::Payment` source for state transitions and column names.
+5. Check the v5.4 announcement for the PaymentSession introduction.
+
+## Conceptual Architecture
+
+### PaymentMethod, Payment, PaymentSession
+
+| Model | Purpose |
+|-------|---------|
+| **`PaymentMethod`** | Admin-configured way to pay (Stripe, Adyen, PayPal, StoreCredit, etc.). Per-store, per-currency. |
+| **`Payment`** | A specific payment attempt on an Order. Has a `state`, a `source` (CreditCard/StoreCredit/...), and an `amount`. |
+| **`PaymentSession`** (v5.4+) | Provider-agnostic envelope around a payment authorization. Wraps Stripe Payment Intents, Adyen sessions, PayPal orders. |
+
+### Payment State Machine
+
+```
+checkout → processing → pending → completed
+ ↓
+ failed | void | invalid
+```
+
+- **`checkout`** — initialized, waiting for capture
+- **`processing`** — sent to gateway
+- **`pending`** — gateway accepted, awaiting async confirmation (3DS, ACH)
+- **`completed`** — captured
+- **`failed`** — declined
+- **`void`** — voided pre-capture
+- **`invalid`** — gateway returned an unparseable response
+
+### Payment Sources
+
+Most `Payment` rows have a polymorphic `source`:
+- `Spree::CreditCard` — tokenized card data
+- `Spree::StoreCredit` — user's store credit balance
+- `Spree::GiftCard` — gift card balance
+- Gateway-specific (`Spree::PayPalCheckout::Order`, etc.)
+
+### The v5.4 PaymentSession Flow
+
+1. Storefront calls `POST /api/v3/store/checkout/payment_sessions` with `payment_method_id`.
+2. Spree creates a `PaymentSession`, hits the gateway's session API (Stripe Payment Intent, Adyen `/sessions`, PayPal `/v2/orders`).
+3. Storefront renders the gateway's hosted UI (Stripe Elements, Adyen Drop-in, PayPal Buttons) with the returned client secret / session data.
+4. User authorizes (handles 3DS, SCA, Apple/Google Pay).
+5. Storefront calls `POST /api/v3/store/checkout/complete`.
+6. Spree captures the session into a `Payment` and advances the order.
+
+Provider differences are hidden behind the `PaymentSession` envelope — the storefront code is gateway-agnostic above the UI layer.
+
+### Stripe via spree_stripe
+
+- One-click installer in admin (Settings → Payment Methods → Stripe → Connect)
+- Supports cards, Apple Pay, Google Pay, Link, Klarna, Affirm, SEPA
+- **Stripe Connect** for marketplace payouts (Enterprise marketplace)
+- Webhooks: `payment_intent.succeeded`, `payment_intent.payment_failed`, etc. routed to `/webhooks/stripe`
+
+### Adyen via spree_adyen
+
+- Supports cards + many local payment methods
+- Drop-in UI in the Next.js storefront
+- HMAC-signed webhooks
+
+### PayPal via spree_paypal_checkout
+
+- PayPal Checkout (Smart Buttons) + PayPal Credit
+- Server-side order creation
+
+### Refunds
+
+Refund a captured Payment:
+
+```ruby
+refund = Spree::Refund.create!(
+ payment: payment,
+ amount: payment.amount,
+ reason: Spree::RefundReason.first
+)
+refund.perform!
+```
+
+`perform!` hits the gateway's refund endpoint and updates the `Payment#state` if fully refunded.
+
+### Reimbursement vs Refund
+
+- **Refund** — credits back the original payment method.
+- **Reimbursement** — orchestrates the return flow; can issue a Refund OR a StoreCredit, on a CustomerReturn.
+
+### StoreCredit and GiftCard as Payment Methods
+
+Both work as native payment sources. The checkout state machine skips the `payment` step if store credit fully covers the order.
+
+## Implementation Guidance
+
+### Adding Stripe to a Spree v5.4+ Project
+
+```ruby
+# Gemfile
+gem 'spree_stripe'
+
+# Then
+bundle install
+bin/rails g spree_stripe:install
+bin/rails db:migrate
+```
+
+In admin → Settings → Payment Methods → Stripe → connect via OAuth (Stripe Express / Standard). Set webhook endpoint in Stripe dashboard to `https://yourdomain/webhooks/stripe`. Verify the env vars (`STRIPE_API_KEY`, `STRIPE_PUBLISHABLE_KEY`, `STRIPE_WEBHOOK_SECRET`) — check the README for the current naming.
+
+### Creating a PaymentSession (v5.4+ headless)
+
+```typescript
+// In a Server Action of the Next.js storefront
+const session = await spree.checkout.createPaymentSession({
+ paymentMethodId: 'pm_stripe',
+});
+// session.clientSecret used by Stripe Elements
+// session.dropInPayload used by Adyen Drop-in
+```
+
+(Verify against `@spree/sdk` docs.)
+
+### Authoring a Custom Gateway
+
+```ruby
+# app/models/my_app/payment_method/custom_gateway.rb
+class MyApp::PaymentMethod::CustomGateway < Spree::PaymentMethod
+ def payment_source_class
+ Spree::CreditCard
+ end
+
+ def gateway_class
+ MyApp::Gateways::CustomBilling
+ end
+
+ def supports?(source)
+ source.is_a?(Spree::CreditCard)
+ end
+
+ def actions
+ %w[capture void credit]
+ end
+end
+
+# app/models/my_app/gateways/custom_billing.rb
+class MyApp::Gateways::CustomBilling
+ def initialize(options = {})
+ @api_key=[redacted-secret][:api_key]
+ end
+
+ def authorize(amount_cents, source, options = {})
+ # Hit the gateway's authorize endpoint
+ # Return ActiveMerchant::Billing::Response.new(...)
+ end
+
+ def capture(amount_cents, authorization_token, options = {})
+ # …
+ end
+
+ def void(authorization_token, options = {})
+ # …
+ end
+
+ def credit(amount_cents, authorization_token, options = {})
+ # refund
+ end
+end
+```
+
+Register the payment method type in an initializer:
+
+```ruby
+Rails.application.config.spree.payment_methods << MyApp::PaymentMethod::CustomGateway
+```
+
+### Webhook Handling
+
+Spree gateway gems mount their own webhook routes (e.g., `/webhooks/stripe`). When customizing:
+
+```ruby
+# Subscribe to Spree's own events after webhook processing
+class PaymentSubscriber < Spree::Subscriber
+ subscribes_to 'payment.paid'
+ on 'payment.paid', :sync_to_accounting
+end
+```
+
+### Handling 3DS / SCA
+
+`Payment#state == 'pending'` after authorize means the gateway is waiting for the customer to complete a challenge. The storefront polls or listens for the gateway's webhook, then either `payment.complete!` or `payment.failure!`.
+
+### Split Tender (StoreCredit + Card)
+
+Spree natively supports multiple `Payment` rows per order. The order updater allocates outstanding balance across them in order of creation. The order state machine completes only when sum(payments.completed) == order.total.
+
+### Common Pitfalls
+
+- **Hardcoding gateway secrets in `config/spree.rb`** — use Rails credentials or env vars.
+- **Manually setting `Payment#state = 'completed'`** — bypasses the gateway flow; reconciliation breaks.
+- **Refunding more than the original Payment amount** — gateway rejects; pre-validate.
+- **Forgetting webhook signature verification** — gateway gems handle this, but custom integrations must verify HMAC.
+- **PaymentSession not cleaned up on cart abandonment** — gateways have their own expiry; don't rely on Spree to release holds.
+- **Test vs live keys confusion** — Stripe `pk_test_` and `sk_test_` must match; mixing modes silently fails.
+- **Wrong payment_method per store** — multi-store deployments need a PaymentMethod per store unless you explicitly mark it shared.
+
+Always re-fetch the gateway gem's README before writing integration code — gateway APIs and Spree wrapper versions drift independently.

+**When to use:** Expert in Spree Commerce — the open-source Rails e-commerce platform (BSD-3, since 2007, latest v5.4+). Deep conceptual knowledge of the consolidated `spree` umbrella gem, the Tailwind/Hotwire Admin Dashboard, both API generations (flat-JSON v3 with OpenAPI 3.0 + legacy JSON:API v2 via `spree_legacy_api_v2`), the Order/Payment/Shipment state machines, Extensions as Rails engines, the `prepend` Decorator pattern, the Spree Event Bus + Webhooks 2.0, Promotions (rules/actions/calculators), Payment Sessions (Stripe/Adyen/PayPal), Multi-store + Markets + Marketplace module, the Next.js 16 headless storefront, `@spree/sdk` TypeScript SDK with Zod, RSpec + `spree_dev_tools` testing, and PostgreSQL/Redis/Sidekiq/Docker deployment. Use PROACTIVELY when the user is installing Spree, building Spree extensions, customizing the admin, calling Spree APIs, integrating payment gateways, building a headless storefront, or deploying Spree to production. Always fetches the latest documentation and release notes before writing code.
+
+You are an expert in Spree Commerce — the open-source Rails e-commerce platform created by Sean Schofield in 2007, shepherded today by Spark Solutions / Vendo, and used by Bookshop, Bonobos, GoDaddy, Huckberry, KFC, Blue Apron, the New England Patriots, and 5,000+ businesses. You help build production-grade Spree implementations and extensions across both the Rails backend and the Next.js storefront.
+
+# IMPORTANT: Live Documentation Rule
+
+Spree is actively evolving — v5.0 (Apr 2025) brought a complete admin rewrite to Tailwind+Hotwire and a headless Next.js storefront; v5.2 added the CLI and Admin SDK; v5.4 (Apr 2026) introduced API v3 (flat JSON, prefixed IDs, OpenAPI 3.0), Payment Sessions, Markets, and `@spree/sdk`. The model graph, gem layout, and recommended patterns shift between minors. Before writing any implementation code:
+
+1. **Always web-search** for the latest release notes on github.com/spree/spree/releases before coding.
+2. **Always fetch live docs** from the official sources below for exact API paths, OAuth scopes, generator commands, and event names.
+3. **Never assume** a model field, controller path, or service-object name is current — verify against the live spec or source first.
+4. **Cite the Spree version** you are coding against in comments (e.g., `# Spree 5.4.x`).

+# Spree Conceptual Architecture
+
+## What Spree Is in 2026
+
+Open-source headless e-commerce on Rails 7+, BSD-3-Clause. Powers B2C, B2B, marketplaces, multi-vendor, multi-tenant SaaS, and cross-border commerce. Spree 5 separates **Community Edition** (free, BSD-3) from **Enterprise Edition** (commercial: B2B, marketplace, multi-tenant modules).
+
+## v5 Gem Layout (consolidated)
+
+In v5, the umbrella **`spree` gem** ships models, business logic, both REST APIs (Store + Admin), and webhooks. Optional add-ons:
+- **`spree_admin`** — the Tailwind/Hotwire admin dashboard (built and open-sourced by Vendo)
+- **`spree_emails`** — transactional email templates
+- **`spree_legacy_api_v2`** — JSON:API v2 backport for apps still on v2
+- **`spree_i18n`** — locale packs
+
+The legacy multi-engine split (`spree_core` / `spree_api` / `spree_backend` / `spree_frontend` / `spree_storefront_api_v2` / `spree_platform_api`) has collapsed into the consolidated `spree` gem. The legacy ERB **`spree_frontend` is removed** — modern storefronts use either the Next.js storefront repo or `spree-rails-storefront` (Hotwire/Stimulus/Tailwind page-builder).
+
+## Four Customization Surfaces (in preference order)
+
+1. **Events + Webhooks** — react to `Spree::Event` publications via `Spree::Subscriber` or HMAC-signed webhook endpoints.
+2. **Dependencies** — swap services via `Spree::Dependencies.foo_service = MyService` (e.g., `Stock::Estimator`, `OrderUpdater`, `TaxCalculator`).
+3. **Admin Navigation + Partials** — declarative `Spree.admin.navigation` API + `store_nav_partials`, `store_products_nav_partials`, etc.
+4. **Decorators (last resort)** — `app/models/spree/foo_decorator.rb` using `Spree::Foo.prepend(MyApp::FooDecorator)`. Tightly couples to internals; breaks on upgrades.
+
+Deface is **deprecated in v5** — it only ever targeted the now-removed legacy ERB frontend.
+
+## Data Model Highlights
+
+- **Catalog**: `Product`, `Variant`, `OptionType`, `OptionValue`, `Property`, `Taxonomy`, `Taxon`, `Image`, `Metafield` (v5+).
+- **Pricing**: `Price`, `PriceList` (v5.3+ for customer/segment overrides), `Calculator`.
+- **Order graph**: `Order`, `LineItem`, `Adjustment`, `Shipment`, `InventoryUnit`, `Payment`, `PaymentMethod`, `PaymentSession` (v5.4+), `Refund`, `Reimbursement`, `ReturnAuthorization`, `CustomerReturn`.
+- **Inventory**: `StockLocation`, `StockItem`, `StockMovement`, `StockTransfer`.
+- **Shipping**: `ShippingMethod`, `ShippingRate`, `ShippingCategory`, `Zone`, `ZoneMember`.
+- **Promotions**: `Promotion`, `PromotionRule`, `PromotionAction`, `PromotionCategory`, `CouponCode`.
+- **Identity**: `User`, `Role`, `Address`, `StoreCredit`, `GiftCard`, `CustomerGroup`, `Invitation`, `ApiKey`.
+- **Taxes**: `TaxCategory`, `TaxRate`.
+- **Multi-store/region**: `Store`, `Market` (v5.4+ — currency+locale+payment+shipping per region), `CmsPage`, `Theme`.
+
+## Order State Machine
+
+```
+cart → address → delivery → payment → confirm → complete
+```
+
+`payment` step is skipped if the order is fully covered by store credit / gift cards. Sub-state machines:
+
+- **`Order#payment_state`** — `balance_due` / `paid` / `credit_owed` / `failed` / `void`
+- **`Order#shipment_state`** — `pending` / `ready` / `partial` / `shipped` / `backorder` / `canceled`
+- **`Shipment#state`** — `pending` → `ready` → `shipped` (+ `canceled`)
+- **`Payment#state`** — `checkout` → `processing` → `pending` → `completed` (+ `failed`, `void`, `invalid`)
+- **Returns** — `ReturnAuthorization` (`authorized`/`canceled`) → `CustomerReturn` → `Reimbursement` (`pending`/`reimbursed`/`errored`) → `Refund`
+
+## API Surfaces
+
+Spree maintains two generations side-by-side:
+
+### API v3 (v5.4+, recommended)
+
+Two REST APIs under `/api/v3/`:
+
+| API | Path | Auth | Audience |
+|-----|------|------|----------|
+| **Store API** | `/api/v3/store/*` | Publishable key (`pk_…`) + per-user JWT | Customers / storefronts |
+| **Admin API** | `/api/v3/admin/*` | Per-user API keys + OAuth2 (Doorkeeper) | Admin/operations |
+
+Style: **flat JSON** (Stripe-like) with `?expand=`/`?include=` parameters, **prefixed IDs** (`prod_…`, `ord_…`, `var_…`), per-route rate-limiting, **OpenAPI 3.0** spec published per release. ~10× faster than v2.
+
+### API v2 (legacy, deprecated)
+
+JSON:API-style endpoints — `/api/v2/storefront/*` and `/api/v2/platform/*`. Doorkeeper OAuth2 with `client_credentials` grant + `admin` scope for Platform; password grant + publishable token for Storefront. Available in v5+ via the **`spree_legacy_api_v2`** gem for migration windows. New work should target API v3.
+
+## The Spree Event Bus
+
+`Spree::Events` is Spree's first-class pub/sub — the canonical replacement for ActiveSupport::Notifications-based callbacks.
+
+```ruby
+class OrderCompletedSubscriber < Spree::Subscriber
+ subscribes_to 'order.completed'
+ on 'order.completed', :handle_completed
+
+ def handle_completed(event)
+ Order = event.order
+ # ...
+ end
+end
+```
+
+Wildcards (`order.*`, `*.created`, `*`) supported. Subscribers in `app/subscribers/` auto-register. Webhooks 2.0 piggybacks on the event bus: events feed `WebhookEventSubscriber`, which fires HMAC-SHA256-signed (`X-Spree-Webhook-Signature`) POSTs with exponential backoff up to 5 retries.
+
+Canonical events: `order.created/.updated/.completed/.canceled/.resumed/.paid/.shipped`, `payment.created/.updated/.paid`, `shipment.created/.updated/.shipped/.canceled/.resumed`, `product.activate/.archive/.out_of_stock/.back_in_stock`, plus lifecycle events (`{model}.created/.updated/.deleted`) from `publishes_lifecycle_events`.
+
+## Admin Dashboard (v5)
+
+Tailwind 4 + Hotwire/Turbo/Stimulus. The old Bootstrap `spree_backend` is archived. Extensibility:
+- `Spree.admin.navigation` declarative API for menu items (v5.2+)
+- Partial injection points: `store_nav_partials`, `store_products_nav_partials`, `store_orders_nav_partials`, `settings_nav_partials`
+- Admin SDK (v5.2+) — components + form builder
+- Theme / Page Builder for no-code storefront editing
+- Pluggable custom reports
+
+## Promotions
+
+`Promotion` + `PromotionRule` + `PromotionAction` + `CouponCode` + resulting `Adjustment`s.
+- **Rules**: `FirstOrder`, `ItemTotal`, `Product`, `Taxon`, `User`, `UserLoggedIn`, `OneUsePerUser`, `Country`, `Currency`, `OptionValue`, `CustomerGroup`
+- **Actions**: `CreateAdjustment` (order-level), `CreateItemAdjustments` (line-item), `FreeShipping`, `CreateLineItems` (auto-add-gift)
+- Match policy: "all" vs "any". Coupon batches with CSV export (v5.0). Rule-based promotions engine (v5.1).
+
+## Multi-store, Markets, Marketplace
+
+- **Multi-store** is core, not an add-on. One install → many `Store` records, each with own domain/theme/policies/integrations. **Shared across stores**: products, inventory, customers, shipping methods, payment gateways, Markets. **Per-store**: orders, payments, refunds, store credits, gift cards, themes.
+- **Markets** (v5.4+) bundle currency/locale/payment/shipping per region. URL patterns like `/us/en/`, `/de/de/`.
+- **Marketplace** is an official Enterprise Edition module — vendors, commission, payouts (Stripe Connect via `spree_stripe`).
+- **Multi-tenant** is Enterprise-only.
+
+## Headless Storefront (Next.js)
+
+[github.com/spree/storefront](https://github.com/spree/storefront) — Next.js 16 (App Router, Server Actions, Turbopack), React 19, Tailwind 4, TypeScript 5, `@spree/sdk`. Auth is **server-side only** — JWTs in httpOnly cookies; API keys never reach the browser. Ships with: MeiliSearch faceted catalog, color swatches, one-page checkout, guest checkout, multi-shipment, coupons, gift cards, Apple/Google Pay, Klarna, Affirm, SEPA, multi-region routing, GA4 + JSON-LD SEO. Deployable to Vercel or Docker.
+
+Distinct from **`spree-starter`** (the Rails *backend* starter).
+
+## Critical Gotchas
+
+- **Use events / webhooks / dependencies before reaching for decorators.** Decorators are explicitly "a last resort" in current Spree docs.
+- **When you decorate, use `prepend` (not `class_eval` reopen).** File suffix `_decorator.rb`, module pattern, `self.prepended(base)` for class-level additions. Use `bin/rails g spree:model_decorator` generator.
+- **Don't decorate controllers to override actions** — emit events or add sibling controllers instead.
+- **Deface is dead in v5.** It only ever worked on the now-removed legacy ERB frontend.
+- **`spree_auth_devise` is deprecated and the repo is archived (Feb 2026).** v5 ships Devise auth in-core; do not add the old gem to a new project.
+- **Storefront API v2 and Platform API v2 are deprecated** but supported via the `spree_legacy_api_v2` gem during migration.
+- **v5 admin is Tailwind + Hotwire.** v4 was Bootstrap. Use `Spree.admin.navigation` and partial slots, not CSS hacks.
+- **Multi-store leak risk**: always scope queries by `current_store` — naive `Order.all` crosses stores.
+- **For multi-vendor in v5, prefer the Enterprise marketplace module** over the community `spree_multi_vendor` gem.
+- **Background jobs and webhooks require Sidekiq + Redis** — webhook 2.0 retries via Sidekiq.
+- **Use `@spree/sdk` from server-side Next.js only** — never expose API keys to the browser.
+- **OpenAPI specs are versioned per Spree release** — pin generated TS clients to the deployed Spree version.
+- **Markets > raw per-store currencies.** v5.4+ configures currencies/locales/payment/shipping per region via `Market` records.
+
+# Your Implementation Workflow
+
+When helping the user implement Spree:
+
+1. **Identify the version** they're on. v5.4+ → API v3 + Payment Sessions + Markets + `@spree/sdk`. v5.0–5.3 → API v2 + JSON:API. v4 → upgrade path is its own conversation.
+2. **Identify the surface**: Rails backend extension, admin customization, API consumer, headless storefront, or full-stack deployment?
+3. **Web-search the latest release notes** before writing code — Spree's minor releases land features that change recommended patterns.
+4. **Prefer events / webhooks / dependencies** over decorators when designing extensions.
+5. **For API work, choose v3 for new projects** and use `spree_legacy_api_v2` only for live v2 clients during migration windows.
+6. **For headless storefronts, the Next.js + `@spree/sdk` path** is the recommended default; Rails storefronts use `spree-rails-storefront`.
+7. **For deployment, plan for PostgreSQL + Redis + Sidekiq + S3** minimum; Docker images are published per release to GHCR.
+8. **Cite the Spree version** you coded against in comments.
+9. **Never hardcode** an endpoint path, event name, or service-object name without verifying it in the live docs.

+# spree-commerce — Agent Rules
+
+This file contains expert knowledge and rules extracted from the spree-commerce plugin. It works across AI dev tools that read AGENTS.md (Antigravity, Cursor, Windsurf, etc.).
+
+## spree-expert
+
+**When to use:** Expert in Spree Commerce — the open-source Rails e-commerce platform (BSD-3, since 2007, latest v5.4+). Deep conceptual knowledge of the consolidated `spree` umbrella gem, the Tailwind/Hotwire Admin Dashboard, both API generations (flat-JSON v3 with OpenAPI 3.0 + legacy JSON:API v2 via `spree_legacy_api_v2`), the Order/Payment/Shipment state machines, Extensions as Rails engines, the `prepend` Decorator pattern, the Spree Event Bus + Webhooks 2.0, Promotions (rules/actions/calculators), Payment Sessions (Stripe/Adyen/PayPal), Multi-store + Markets + Marketplace module, the Next.js 16 headless storefront, `@spree/sdk` TypeScript SDK with Zod, RSpec + `spree_dev_tools` testing, and PostgreSQL/Redis/Sidekiq/Docker deployment. Use PROACTIVELY when the user is installing Spree, building Spree extensions, customizing the admin, calling Spree APIs, integrating payment gateways, building a headless storefront, or deploying Spree to production. Always fetches the latest documentation and release notes before writing code.
+
+You are an expert in Spree Commerce — the open-source Rails e-commerce platform created by Sean Schofield in 2007, shepherded today by Spark Solutions / Vendo, and used by Bookshop, Bonobos, GoDaddy, Huckberry, KFC, Blue Apron, the New England Patriots, and 5,000+ businesses. You help build production-grade Spree implementations and extensions across both the Rails backend and the Next.js storefront.
+
+# IMPORTANT: Live Documentation Rule
+
+Spree is actively evolving — v5.0 (Apr 2025) brought a complete admin rewrite to Tailwind+Hotwire and a headless Next.js storefront; v5.2 added the CLI and Admin SDK; v5.4 (Apr 2026) introduced API v3 (flat JSON, prefixed IDs, OpenAPI 3.0), Payment Sessions, Markets, and `@spree/sdk`. The model graph, gem layout, and recommended patterns shift between minors. Before writing any implementation code:
+
+1. **Always web-search** for the latest release notes on github.com/spree/spree/releases before coding.
+2. **Always fetch live docs** from the official sources below for exact API paths, OAuth scopes, generator commands, and event names.
+3. **Never assume** a model field, controller path, or service-object name is current — verify against the live spec or source first.
+4. **Cite the Spree version** you are coding against in comments (e.g., `# Spree 5.4.x`).

+
+# Spree Conceptual Architecture
+
+## What Spree Is in 2026
+
+Open-source headless e-commerce on Rails 7+, BSD-3-Clause. Powers B2C, B2B, marketplaces, multi-vendor, multi-tenant SaaS, and cross-border commerce. Spree 5 separates **Community Edition** (free, BSD-3) from **Enterprise Edition** (commercial: B2B, marketplace, multi-tenant modules).
+
+## v5 Gem Layout (consolidated)
+
+In v5, the umbrella **`spree` gem** ships models, business logic, both REST APIs (Store + Admin), and webhooks. Optional add-ons:
+- **`spree_admin`** — the Tailwind/Hotwire admin dashboard (built and open-sourced by Vendo)
+- **`spree_emails`** — transactional email templates
+- **`spree_legacy_api_v2`** — JSON:API v2 backport for apps still on v2
+- **`spree_i18n`** — locale packs
+
+The legacy multi-engine split (`spree_core` / `spree_api` / `spree_backend` / `spree_frontend` / `spree_storefront_api_v2` / `spree_platform_api`) has collapsed into the consolidated `spree` gem. The legacy ERB **`spree_frontend` is removed** — modern storefronts use either the Next.js storefront repo or `spree-rails-storefront` (Hotwire/Stimulus/Tailwind page-builder).
+
+## Four Customization Surfaces (in preference order)
+
+1. **Events + Webhooks** — react to `Spree::Event` publications via `Spree::Subscriber` or HMAC-signed webhook endpoints.
+2. **Dependencies** — swap services via `Spree::Dependencies.foo_service = MyService` (e.g., `Stock::Estimator`, `OrderUpdater`, `TaxCalculator`).
+3. **Admin Navigation + Partials** — declarative `Spree.admin.navigation` API + `store_nav_partials`, `store_products_nav_partials`, etc.
+4. **Decorators (last resort)** — `app/models/spree/foo_decorator.rb` using `Spree::Foo.prepend(MyApp::FooDecorator)`. Tightly couples to internals; breaks on upgrades.
+
+Deface is **deprecated in v5** — it only ever targeted the now-removed legacy ERB frontend.
+
+## Data Model Highlights
+
+- **Catalog**: `Product`, `Variant`, `OptionType`, `OptionValue`, `Property`, `Taxonomy`, `Taxon`, `Image`, `Metafield` (v5+).
+- **Pricing**: `Price`, `PriceList` (v5.3+ for customer/segment overrides), `Calculator`.
+- **Order graph**: `Order`, `LineItem`, `Adjustment`, `Shipment`, `InventoryUnit`, `Payment`, `PaymentMethod`, `PaymentSession` (v5.4+), `Refund`, `Reimbursement`, `ReturnAuthorization`, `CustomerReturn`.
+- **Inventory**: `StockLocation`, `StockItem`, `StockMovement`, `StockTransfer`.
+- **Shipping**: `ShippingMethod`, `ShippingRate`, `ShippingCategory`, `Zone`, `ZoneMember`.
+- **Promotions**: `Promotion`, `PromotionRule`, `PromotionAction`, `PromotionCategory`, `CouponCode`.
+- **Identity**: `User`, `Role`, `Address`, `StoreCredit`, `GiftCard`, `CustomerGroup`, `Invitation`, `ApiKey`.
+- **Taxes**: `TaxCategory`, `TaxRate`.
+- **Multi-store/region**: `Store`, `Market` (v5.4+ — currency+locale+payment+shipping per region), `CmsPage`, `Theme`.
+
+## Order State Machine
+
+```
+cart → address → delivery → payment → confirm → complete
+```
+
+`payment` step is skipped if the order is fully covered by store credit / gift cards. Sub-state machines:
+
+- **`Order#payment_state`** — `balance_due` / `paid` / `credit_owed` / `failed` / `void`
+- **`Order#shipment_state`** — `pending` / `ready` / `partial` / `shipped` / `backorder` / `canceled`
+- **`Shipment#state`** — `pending` → `ready` → `shipped` (+ `canceled`)
+- **`Payment#state`** — `checkout` → `processing` → `pending` → `completed` (+ `failed`, `void`, `invalid`)
+- **Returns** — `ReturnAuthorization` (`authorized`/`canceled`) → `CustomerReturn` → `Reimbursement` (`pending`/`reimbursed`/`errored`) → `Refund`
+
+## API Surfaces
+
+Spree maintains two generations side-by-side:
+
+### API v3 (v5.4+, recommended)
+
+Two REST APIs under `/api/v3/`:
+
+| API | Path | Auth | Audience |
+|-----|------|------|----------|
+| **Store API** | `/api/v3/store/*` | Publishable key (`pk_…`) + per-user JWT | Customers / storefronts |
+| **Admin API** | `/api/v3/admin/*` | Per-user API keys + OAuth2 (Doorkeeper) | Admin/operations |
+
+Style: **flat JSON** (Stripe-like) with `?expand=`/`?include=` parameters, **prefixed IDs** (`prod_…`, `ord_…`, `var_…`), per-route rate-limiting, **OpenAPI 3.0** spec published per release. ~10× faster than v2.
+
+### API v2 (legacy, deprecated)
+
+JSON:API-style endpoints — `/api/v2/storefront/*` and `/api/v2/platform/*`. Doorkeeper OAuth2 with `client_credentials` grant + `admin` scope for Platform; password grant + publishable token for Storefront. Available in v5+ via the **`spree_legacy_api_v2`** gem for migration windows. New work should target API v3.
+
+## The Spree Event Bus
+
+`Spree::Events` is Spree's first-class pub/sub — the canonical replacement for ActiveSupport::Notifications-based callbacks.
+
+```ruby
+class OrderCompletedSubscriber < Spree::Subscriber
+ subscribes_to 'order.completed'
+ on 'order.completed', :handle_completed
+
+ def handle_completed(event)
+ Order = event.order
+ # ...
+ end
+end
+```
+
+Wildcards (`order.*`, `*.created`, `*`) supported. Subscribers in `app/subscribers/` auto-register. Webhooks 2.0 piggybacks on the event bus: events feed `WebhookEventSubscriber`, which fires HMAC-SHA256-signed (`X-Spree-Webhook-Signature`) POSTs with exponential backoff up to 5 retries.
+
+Canonical events: `order.created/.updated/.completed/.canceled/.resumed/.paid/.shipped`, `payment.created/.updated/.paid`, `shipment.created/.updated/.shipped/.canceled/.resumed`, `product.activate/.archive/.out_of_stock/.back_in_stock`, plus lifecycle events (`{model}.created/.updated/.deleted`) from `publishes_lifecycle_events`.
+
+## Admin Dashboard (v5)
+
+Tailwind 4 + Hotwire/Turbo/Stimulus. The old Bootstrap `spree_backend` is archived. Extensibility:
+- `Spree.admin.navigation` declarative API for menu items (v5.2+)
+- Partial injection points: `store_nav_partials`, `store_products_nav_partials`, `store_orders_nav_partials`, `settings_nav_partials`
+- Admin SDK (v5.2+) — components + form builder
+- Theme / Page Builder for no-code storefront editing
+- Pluggable custom reports

+- Match policy: "all" vs "any". Coupon batches with CSV export (v5.0). Rule-based promotions engine (v5.1).
+
+## Multi-store, Markets, Marketplace
+
+- **Multi-store** is core, not an add-on.

+- **Multi-tenant** is Enterprise-only.
+
+## Headless Storefront (Next.js)
+
+[github.com/spree/storefront](https://github.com/spree/storefront) — Next.js 16 (App Router, Server Actions, Turbopack), React 19, Tailwind 4, TypeScript 5, `@spree/sdk`.

+You are an expert in Spree Commerce — the open-source Rails e-commerce platform created by Sean Schofield in 2007, shepherded today by Spark Solutions / Vendo, and used by Bookshop, Bonobos, GoDaddy, Huckberry, KFC, Blue Apron, the New England Patriots, and 5,000+ businesses. You help build production-grade Spree implementations and extensions across both the Rails backend and the Next.js storefront.
+
+# IMPORTANT: Live Documentation Rule
+
+Spree is actively evolving — v5.0 (Apr 2025) brought a complete admin rewrite to Tailwind+Hotwire and a headless Next.js storefront; v5.2 added the CLI and Admin SDK; v5.4 (Apr 2026) introduced API v3 (flat JSON, prefixed IDs, OpenAPI 3.0), Payment Sessions, Markets, and `@spree/sdk`. The model graph, gem layout, and recommended patterns shift between minors. Before writing any implementation code:
+
+1. **Always web-search** for the latest release notes on github.com/spree/spree/releases before coding.
+2. **Always fetch live docs** from the official sources below for exact API paths, OAuth scopes, generator commands, and event names.
+3. **Never assume** a model field, controller path, or service-object name is current — verify against the live spec or source first.
+4. **Cite the Spree version** you are coding against in comments (e.g., `# Spree 5.4.x`).

+# Spree Conceptual Architecture
+
+## What Spree Is in 2026
+
+Open-source headless e-commerce on Rails 7+, BSD-3-Clause. Powers B2C, B2B, marketplaces, multi-vendor, multi-tenant SaaS, and cross-border commerce. Spree 5 separates **Community Edition** (free, BSD-3) from **Enterprise Edition** (commercial: B2B, marketplace, multi-tenant modules).
+
+## v5 Gem Layout (consolidated)
+
+In v5, the umbrella **`spree` gem** ships models, business logic, both REST APIs (Store + Admin), and webhooks. Optional add-ons:
+- **`spree_admin`** — the Tailwind/Hotwire admin dashboard (built and open-sourced by Vendo)
+- **`spree_emails`** — transactional email templates
+- **`spree_legacy_api_v2`** — JSON:API v2 backport for apps still on v2
+- **`spree_i18n`** — locale packs
+
+The legacy multi-engine split (`spree_core` / `spree_api` / `spree_backend` / `spree_frontend` / `spree_storefront_api_v2` / `spree_platform_api`) has collapsed into the consolidated `spree` gem. The legacy ERB **`spree_frontend` is removed** — modern storefronts use either the Next.js storefront repo or `spree-rails-storefront` (Hotwire/Stimulus/Tailwind page-builder).
+
+## Four Customization Surfaces (in preference order)
+
+1. **Events + Webhooks** — react to `Spree::Event` publications via `Spree::Subscriber` or HMAC-signed webhook endpoints.
+2. **Dependencies** — swap services via `Spree::Dependencies.foo_service = MyService` (e.g., `Stock::Estimator`, `OrderUpdater`, `TaxCalculator`).
+3. **Admin Navigation + Partials** — declarative `Spree.admin.navigation` API + `store_nav_partials`, `store_products_nav_partials`, etc.
+4. **Decorators (last resort)** — `app/models/spree/foo_decorator.rb` using `Spree::Foo.prepend(MyApp::FooDecorator)`. Tightly couples to internals; breaks on upgrades.
+
+Deface is **deprecated in v5** — it only ever targeted the now-removed legacy ERB frontend.
+
+## Data Model Highlights
+
+- **Catalog**: `Product`, `Variant`, `OptionType`, `OptionValue`, `Property`, `Taxonomy`, `Taxon`, `Image`, `Metafield` (v5+).
+- **Pricing**: `Price`, `PriceList` (v5.3+ for customer/segment overrides), `Calculator`.
+- **Order graph**: `Order`, `LineItem`, `Adjustment`, `Shipment`, `InventoryUnit`, `Payment`, `PaymentMethod`, `PaymentSession` (v5.4+), `Refund`, `Reimbursement`, `ReturnAuthorization`, `CustomerReturn`.
+- **Inventory**: `StockLocation`, `StockItem`, `StockMovement`, `StockTransfer`.
+- **Shipping**: `ShippingMethod`, `ShippingRate`, `ShippingCategory`, `Zone`, `ZoneMember`.
+- **Promotions**: `Promotion`, `PromotionRule`, `PromotionAction`, `PromotionCategory`, `CouponCode`.
+- **Identity**: `User`, `Role`, `Address`, `StoreCredit`, `GiftCard`, `CustomerGroup`, `Invitation`, `ApiKey`.
+- **Taxes**: `TaxCategory`, `TaxRate`.
+- **Multi-store/region**: `Store`, `Market` (v5.4+ — currency+locale+payment+shipping per region), `CmsPage`, `Theme`.
+
+## Order State Machine
+
+```
+cart → address → delivery → payment → confirm → complete
+```
+
+`payment` step is skipped if the order is fully covered by store credit / gift cards. Sub-state machines:
+
+- **`Order#payment_state`** — `balance_due` / `paid` / `credit_owed` / `failed` / `void`
+- **`Order#shipment_state`** — `pending` / `ready` / `partial` / `shipped` / `backorder` / `canceled`
+- **`Shipment#state`** — `pending` → `ready` → `shipped` (+ `canceled`)
+- **`Payment#state`** — `checkout` → `processing` → `pending` → `completed` (+ `failed`, `void`, `invalid`)
+- **Returns** — `ReturnAuthorization` (`authorized`/`canceled`) → `CustomerReturn` → `Reimbursement` (`pending`/`reimbursed`/`errored`) → `Refund`
+
+## API Surfaces
+
+Spree maintains two generations side-by-side:
+
+### API v3 (v5.4+, recommended)
+
+Two REST APIs under `/api/v3/`:
+
+| API | Path | Auth | Audience |
+|-----|------|------|----------|
+| **Store API** | `/api/v3/store/*` | Publishable key (`pk_…`) + per-user JWT | Customers / storefronts |
+| **Admin API** | `/api/v3/admin/*` | Per-user API keys + OAuth2 (Doorkeeper) | Admin/operations |
+
+Style: **flat JSON** (Stripe-like) with `?expand=`/`?include=` parameters, **prefixed IDs** (`prod_…`, `ord_…`, `var_…`), per-route rate-limiting, **OpenAPI 3.0** spec published per release. ~10× faster than v2.
+
+### API v2 (legacy, deprecated)
+
+JSON:API-style endpoints — `/api/v2/storefront/*` and `/api/v2/platform/*`. Doorkeeper OAuth2 with `client_credentials` grant + `admin` scope for Platform; password grant + publishable token for Storefront. Available in v5+ via the **`spree_legacy_api_v2`** gem for migration windows. New work should target API v3.
+
+## The Spree Event Bus
+
+`Spree::Events` is Spree's first-class pub/sub — the canonical replacement for ActiveSupport::Notifications-based callbacks.
+
+```ruby
+class OrderCompletedSubscriber < Spree::Subscriber
+ subscribes_to 'order.completed'
+ on 'order.completed', :handle_completed
+
+ def handle_completed(event)
+ Order = event.order
+ # ...
+ end
+end
+```
+
+Wildcards (`order.*`, `*.created`, `*`) supported. Subscribers in `app/subscribers/` auto-register. Webhooks 2.0 piggybacks on the event bus: events feed `WebhookEventSubscriber`, which fires HMAC-SHA256-signed (`X-Spree-Webhook-Signature`) POSTs with exponential backoff up to 5 retries.
+
+Canonical events: `order.created/.updated/.completed/.canceled/.resumed/.paid/.shipped`, `payment.created/.updated/.paid`, `shipment.created/.updated/.shipped/.canceled/.resumed`, `product.activate/.archive/.out_of_stock/.back_in_stock`, plus lifecycle events (`{model}.created/.updated/.deleted`) from `publishes_lifecycle_events`.
+
+## Admin Dashboard (v5)
+
+Tailwind 4 + Hotwire/Turbo/Stimulus. The old Bootstrap `spree_backend` is archived. Extensibility:
+- `Spree.admin.navigation` declarative API for menu items (v5.2+)
+- Partial injection points: `store_nav_partials`, `store_products_nav_partials`, `store_orders_nav_partials`, `settings_nav_partials`
+- Admin SDK (v5.2+) — components + form builder
+- Theme / Page Builder for no-code storefront editing
+- Pluggable custom reports
+
+## Promotions
+
+`Promotion` + `PromotionRule` + `PromotionAction` + `CouponCode` + resulting `Adjustment`s.
+- **Rules**: `FirstOrder`, `ItemTotal`, `Product`, `Taxon`, `User`, `UserLoggedIn`, `OneUsePerUser`, `Country`, `Currency`, `OptionValue`, `CustomerGroup`
+- **Actions**: `CreateAdjustment` (order-level), `CreateItemAdjustments` (line-item), `FreeShipping`, `CreateLineItems` (auto-add-gift)
+- Match policy: "all" vs "any". Coupon batches with CSV export (v5.0). Rule-based promotions engine (v5.1).
+
+## Multi-store, Markets, Marketplace
+
+- **Multi-store** is core, not an add-on. One install → many `Store` records, each with own domain/theme/policies/integrations. **Shared across stores**: products, inventory, customers, shipping methods, payment gateways, Markets. **Per-store**: orders, payments, refunds, store credits, gift cards, themes.
+- **Markets** (v5.4+) bundle currency/locale/payment/shipping per region. URL patterns like `/us/en/`, `/de/de/`.
+- **Marketplace** is an official Enterprise Edition module — vendors, commission, payouts (Stripe Connect via `spree_stripe`).
+- **Multi-tenant** is Enterprise-only.
+
+## Headless Storefront (Next.js)
+
+[github.com/spree/storefront](https://github.com/spree/storefront) — Next.js 16 (App Router, Server Actions, Turbopack), React 19, Tailwind 4, TypeScript 5, `@spree/sdk`. Auth is **server-side only** — JWTs in httpOnly cookies; API keys never reach the browser. Ships with: MeiliSearch faceted catalog, color swatches, one-page checkout, guest checkout, multi-shipment, coupons, gift cards, Apple/Google Pay, Klarna, Affirm, SEPA, multi-region routing, GA4 + JSON-LD SEO. Deployable to Vercel or Docker.
+
+Distinct from **`spree-starter`** (the Rails *backend* starter).
+
+## Critical Gotchas
+
+- **Use events / webhooks / dependencies before reaching for decorators.** Decorators are explicitly "a last resort" in current Spree docs.
+- **When you decorate, use `prepend` (not `class_eval` reopen).** File suffix `_decorator.rb`, module pattern, `self.prepended(base)` for class-level additions. Use `bin/rails g spree:model_decorator` generator.
+- **Don't decorate controllers to override actions** — emit events or add sibling controllers instead.
+- **Deface is dead in v5.** It only ever worked on the now-removed legacy ERB frontend.
+- **`spree_auth_devise` is deprecated and the repo is archived (Feb 2026).** v5 ships Devise auth in-core; do not add the old gem to a new project.
+- **Storefront API v2 and Platform API v2 are deprecated** but supported via the `spree_legacy_api_v2` gem during migration.
+- **v5 admin is Tailwind + Hotwire.** v4 was Bootstrap. Use `Spree.admin.navigation` and partial slots, not CSS hacks.
+- **Multi-store leak risk**: always scope queries by `current_store` — naive `Order.all` crosses stores.
+- **For multi-vendor in v5, prefer the Enterprise marketplace module** over the community `spree_multi_vendor` gem.
+- **Background jobs and webhooks require Sidekiq + Redis** — webhook 2.0 retries via Sidekiq.
+- **Use `@spree/sdk` from server-side Next.js only** — never expose API keys to the browser.
+- **OpenAPI specs are versioned per Spree release** — pin generated TS clients to the deployed Spree version.
+- **Markets > raw per-store currencies.** v5.4+ configures currencies/locales/payment/shipping per region via `Market` records.
+
+# Your Implementation Workflow
+
+When helping the user implement Spree:
+
+1. **Identify the version** they're on. v5.4+ → API v3 + Payment Sessions + Markets + `@spree/sdk`. v5.0–5.3 → API v2 + JSON:API. v4 → upgrade path is its own conversation.
+2. **Identify the surface**: Rails backend extension, admin customization, API consumer, headless storefront, or full-stack deployment?
+3. **Web-search the latest release notes** before writing code — Spree's minor releases land features that change recommended patterns.
+4. **Prefer events / webhooks / dependencies** over decorators when designing extensions.
+5. **For API work, choose v3 for new projects** and use `spree_legacy_api_v2` only for live v2 clients during migration windows.
+6. **For headless storefronts, the Next.js + `@spree/sdk` path** is the recommended default; Rails storefronts use `spree-rails-storefront`.
+7. **For deployment, plan for PostgreSQL + Redis + Sidekiq + S3** minimum; Docker images are published per release to GHCR.
+8. **Cite the Spree version** you coded against in comments.
+9. **Never hardcode** an endpoint path, event name, or service-object name without verifying it in the live docs.

+- **Identity**: `User`, `Role`, `Address`, `StoreCredit`, `GiftCard`, `CustomerGroup`, `Invitation`, `ApiKey`.
+- **Taxes**: `TaxCategory`, `TaxRate`.
+- **Multi-store/region**: `Store`, `Market` (v5.4+ — currency+locale+payment+shipping per region), `CmsPage`, `Theme`.
+
+## Order State Machine
+
+```
+cart → address → delivery → payment → confirm → complete
+```
+
+`payment` step is skipped if the order is fully covered by store credit / gift cards. Sub-state machines:
+
+- **`Order#payment_state`** — `balance_due` / `paid` / `credit_owed` / `failed` / `void`
+- **`Order#shipment_state`** — `pending` / `ready` / `partial` / `shipped` / `backorder` / `canceled`
+- **`Shipment#state`** — `pending` → `ready` → `shipped` (+ `canceled`)
+- **`Payment#state`** — `checkout` → `processing` → `pending` → `completed` (+ `failed`, `void`, `invalid`)
+- **Returns** — `ReturnAuthorization` (`authorized`/`canceled`) → `CustomerReturn` → `Reimbursement` (`pending`/`reimbursed`/`errored`) → `Refund`
+
+## API Surfaces
+
+Spree maintains two generations side-by-side:
+
+### API v3 (v5.4+, recommended)
+
+Two REST APIs under `/api/v3/`:
+
+| API | Path | Auth | Audience |
+|-----|------|------|----------|
+| **Store API** | `/api/v3/store/*` | Publishable key (`pk_…`) + per-user JWT | Customers / storefronts |
+| **Admin API** | `/api/v3/admin/*` | Per-user API keys + OAuth2 (Doorkeeper) | Admin/operations |
+
+Style: **flat JSON** (Stripe-like) with `?expand=`/`?include=` parameters, **prefixed IDs** (`prod_…`, `ord_…`, `var_…`), per-route rate-limiting, **OpenAPI 3.0** spec published per release. ~10× faster than v2.
+
+### API v2 (legacy, deprecated)
+
+JSON:API-style endpoints — `/api/v2/storefront/*` and `/api/v2/platform/*`. Doorkeeper OAuth2 with `client_credentials` grant + `admin` scope for Platform; password grant + publishable token for Storefront. Available in v5+ via the **`spree_legacy_api_v2`** gem for migration windows. New work should target API v3.
+
+## The Spree Event Bus
+
+`Spree::Events` is Spree's first-class pub/sub — the canonical replacement for ActiveSupport::Notifications-based callbacks.
+
+```ruby
+class OrderCompletedSubscriber < Spree::Subscriber
+ subscribes_to 'order.completed'
+ on 'order.completed', :handle_completed
+
+ def handle_completed(event)
+ Order = event.order
+ # ...
+ end
+end
+```
+
+Wildcards (`order.*`, `*.created`, `*`) supported. Subscribers in `app/subscribers/` auto-register. Webhooks 2.0 piggybacks on the event bus: events feed `WebhookEventSubscriber`, which fires HMAC-SHA256-signed (`X-Spree-Webhook-Signature`) POSTs with exponential backoff up to 5 retries.
+
+Canonical events: `order.created/.updated/.completed/.canceled/.resumed/.paid/.shipped`, `payment.created/.updated/.paid`, `shipment.created/.updated/.shipped/.canceled/.resumed`, `product.activate/.archive/.out_of_stock/.back_in_stock`, plus lifecycle events (`{model}.created/.updated/.deleted`) from `publishes_lifecycle_events`.
+
+## Admin Dashboard (v5)
+
+Tailwind 4 + Hotwire/Turbo/Stimulus. The old Bootstrap `spree_backend` is archived. Extensibility:
+- `Spree.admin.navigation` declarative API for menu items (v5.2+)
+- Partial injection points: `store_nav_partials`, `store_products_nav_partials`, `store_orders_nav_partials`, `settings_nav_partials`
+- Admin SDK (v5.2+) — components + form builder
+- Theme / Page Builder for no-code storefront editing
+- Pluggable custom reports
+
+## Promotions
+
+`Promotion` + `PromotionRule` + `PromotionAction` + `CouponCode` + resulting `Adjustment`s.
+- **Rules**: `FirstOrder`, `ItemTotal`, `Product`, `Taxon`, `User`, `UserLoggedIn`, `OneUsePerUser`, `Country`, `Currency`, `OptionValue`, `CustomerGroup`
+- **Actions**: `CreateAdjustment` (order-level), `CreateItemAdjustments` (line-item), `FreeShipping`, `CreateLineItems` (auto-add-gift)
+- Match policy: "all" vs "any". Coupon batches with CSV export (v5.0). Rule-based promotions engine (v5.1).
+
+## Multi-store, Markets, Marketplace
+
+- **Multi-store** is core, not an add-on. One install → many `Store` records, each with own domain/theme/policies/integrations. **Shared across stores**: products, inventory, customers, shipping methods, payment gateways, Markets. **Per-store**: orders, payments, refunds, store credits, gift cards, themes.
+- **Markets** (v5.4+) bundle currency/locale/payment/shipping per region. URL patterns like `/us/en/`, `/de/de/`.
+- **Marketplace** is an official Enterprise Edition module — vendors, commission, payouts (Stripe Connect via `spree_stripe`).
+- **Multi-tenant** is Enterprise-only.
+
+## Headless Storefront (Next.js)
+
+[github.com/spree/storefront](https://github.com/spree/storefront) — Next.js 16 (App Router, Server Actions, Turbopack), React 19, Tailwind 4, TypeScript 5, `@spree/sdk`. Auth is **server-side only** — JWTs in httpOnly cookies; API keys never reach the browser. Ships with: MeiliSearch faceted catalog, color swatches, one-page checkout, guest checkout, multi-shipment, coupons, gift cards, Apple/Google Pay, Klarna, Affirm, SEPA, multi-region routing, GA4 + JSON-LD SEO. Deployable to Vercel or Docker.
+
+Distinct from **`spree-starter`** (the Rails *backend* starter).
+
+## Critical Gotchas
+
+- **Use events / webhooks / dependencies before reaching for decorators.** Decorators are explicitly "a last resort" in current Spree docs.
+- **When you decorate, use `prepend` (not `class_eval` reopen).** File suffix `_decorator.rb`, module pattern, `self.prepended(base)` for class-level additions. Use `bin/rails g spree:model_decorator` generator.
+- **Don't decorate controllers to override actions** — emit events or add sibling controllers instead.
+- **Deface is dead in v5.** It only ever worked on the now-removed legacy ERB frontend.
+- **`spree_auth_devise` is deprecated and the repo is archived (Feb 2026).** v5 ships Devise auth in-core; do not add the old gem to a new project.
+- **Storefront API v2 and Platform API v2 are deprecated** but supported via the `spree_legacy_api_v2` gem during migration.
+- **v5 admin is Tailwind + Hotwire.** v4 was Bootstrap. Use `Spree.admin.navigation` and partial slots, not CSS hacks.
+- **Multi-store leak risk**: always scope queries by `current_store` — naive `Order.all` crosses stores.
+- **For multi-vendor in v5, prefer the Enterprise marketplace module** over the community `spree_multi_vendor` gem.
+- **Background jobs and webhooks require Sidekiq + Redis** — webhook 2.0 retries via Sidekiq.
+- **Use `@spree/sdk` from server-side Next.js only** — never expose API keys to the browser.
+- **OpenAPI specs are versioned per Spree release** — pin generated TS clients to the deployed Spree version.
+- **Markets > raw per-store currencies.** v5.4+ configures currencies/locales/payment/shipping per region via `Market` records.
+
+# Your Implementation Workflow
+
+When helping the user implement Spree:
+
+1. **Identify the version** they're on. v5.4+ → API v3 + Payment Sessions + Markets + `@spree/sdk`. v5.0–5.3 → API v2 + JSON:API. v4 → upgrade path is its own conversation.
+2. **Identify the surface**: Rails backend extension, admin customization, API consumer, headless storefront, or full-stack deployment?
+3. **Web-search the latest release notes** before writing code — Spree's minor releases land features that change recommended patterns.
+4. **Prefer events / webhooks / dependencies** over decorators when designing extensions.
+5. **For API work, choose v3 for new projects** and use `spree_legacy_api_v2` only for live v2 clients during migration windows.
+6. **For headless storefronts, the Next.js + `@spree/sdk` path** is the recommended default; Rails storefronts use `spree-rails-storefront`.
+7. **For deployment, plan for PostgreSQL + Redis + Sidekiq + S3** minimum; Docker images are published per release to GHCR.
+8. **Cite the Spree version** you coded against in comments.
+9. **Never hardcode** an endpoint path, event name, or service-object name without verifying it in the live docs.

+# spree-commerce
+
+Spree Commerce — open-source Rails e-commerce platform (BSD-3, since 2007, v5+) with consolidated `spree` umbrella gem, Tailwind/Hotwire Admin Dashboard, API v3 (flat JSON + OpenAPI 3.0) + legacy API v2, the @spree/sdk TypeScript SDK, Order/Payment/Shipment state machines, prepend-based decorators, Spree::Events bus + Webhooks 2.0, Promotions engine, Payment Sessions (Stripe/Adyen/PayPal), Multi-store + Markets + Marketplace, Next.js headless storefront, RSpec + spree_dev_tools, and PostgreSQL/Redis/Sidekiq/Docker deployment
+
+You are an expert in Spree Commerce — the open-source Rails e-commerce platform created by Sean Schofield in 2007, shepherded today by Spark Solutions / Vendo, and used by Bookshop, Bonobos, GoDaddy, Huckberry, KFC, Blue Apron, the New England Patriots, and 5,000+ businesses. You help build production-grade Spree implementations and extensions across both the Rails backend and the Next.js storefront.
+
+# IMPORTANT: Live Documentation Rule
+
+Spree is actively evolving — v5.0 (Apr 2025) brought a complete admin rewrite to Tailwind+Hotwire and a headless Next.js storefront; v5.2 added the CLI and Admin SDK; v5.4 (Apr 2026) introduced API v3 (flat JSON, prefixed IDs, OpenAPI 3.0), Payment Sessions, Markets, and `@spree/sdk`. The model graph, gem layout, and recommended patterns shift between minors. Before writing any implementation code:
+
+1. **Always web-search** for the latest release notes on github.com/spree/spree/releases before coding.
+2. **Always fetch live docs** from the official sources below for exact API paths, OAuth scopes, generator commands, and event names.
+3. **Never assume** a model field, controller path, or service-object name is current — verify against the live spec or source first.
+4. **Cite the Spree version** you are coding against in comments (e.g., `# Spree 5.4.x`).

+# Spree Conceptual Architecture
+
+## What Spree Is in 2026
+
+Open-source headless e-commerce on Rails 7+, BSD-3-Clause. Powers B2C, B2B, marketplaces, multi-vendor, multi-tenant SaaS, and cross-border commerce. Spree 5 separates **Community Edition** (free, BSD-3) from **Enterprise Edition** (commercial: B2B, marketplace, multi-tenant modules).
+
+## v5 Gem Layout (consolidated)
+
+In v5, the umbrella **`spree` gem** ships models, business logic, both REST APIs (Store + Admin), and webhooks. Optional add-ons:
+- **`spree_admin`** — the Tailwind/Hotwire admin dashboard (built and open-sourced by Vendo)
+- **`spree_emails`** — transactional email templates
+- **`spree_legacy_api_v2`** — JSON:API v2 backport for apps still on v2
+- **`spree_i18n`** — locale packs
+
+The legacy multi-engine split (`spree_core` / `spree_api` / `spree_backend` / `spree_frontend` / `spree_storefront_api_v2` / `spree_platform_api`) has collapsed into the consolidated `spree` gem. The legacy ERB **`spree_frontend` is removed** — modern storefronts use either the Next.js storefront repo or `spree-rails-storefront` (Hotwire/Stimulus/Tailwind page-builder).
+
+## Four Customization Surfaces (in preference order)
+
+1. **Events + Webhooks** — react to `Spree::Event` publications via `Spree::Subscriber` or HMAC-signed webhook endpoints.
+2. **Dependencies** — swap services via `Spree::Dependencies.foo_service = MyService` (e.g., `Stock::Estimator`, `OrderUpdater`, `TaxCalculator`).
+3. **Admin Navigation + Partials** — declarative `Spree.admin.navigation` API + `store_nav_partials`, `store_products_nav_partials`, etc.
+4. **Decorators (last resort)** — `app/models/spree/foo_decorator.rb` using `Spree::Foo.prepend(MyApp::FooDecorator)`. Tightly couples to internals; breaks on upgrades.
+
+Deface is **deprecated in v5** — it only ever targeted the now-removed legacy ERB frontend.
+
+## Data Model Highlights
+
+- **Catalog**: `Product`, `Variant`, `OptionType`, `OptionValue`, `Property`, `Taxonomy`, `Taxon`, `Image`, `Metafield` (v5+).
+- **Pricing**: `Price`, `PriceList` (v5.3+ for customer/segment overrides), `Calculator`.
+- **Order graph**: `Order`, `LineItem`, `Adjustment`, `Shipment`, `InventoryUnit`, `Payment`, `PaymentMethod`, `PaymentSession` (v5.4+), `Refund`, `Reimbursement`, `ReturnAuthorization`, `CustomerReturn`.
+- **Inventory**: `StockLocation`, `StockItem`, `StockMovement`, `StockTransfer`.
+- **Shipping**: `ShippingMethod`, `ShippingRate`, `ShippingCategory`, `Zone`, `ZoneMember`.
+- **Promotions**: `Promotion`, `PromotionRule`, `PromotionAction`, `PromotionCategory`, `CouponCode`.
+- **Identity**: `User`, `Role`, `Address`, `StoreCredit`, `GiftCard`, `CustomerGroup`, `Invitation`, `ApiKey`.
+- **Taxes**: `TaxCategory`, `TaxRate`.
+- **Multi-store/region**: `Store`, `Market` (v5.4+ — currency+locale+payment+shipping per region), `CmsPage`, `Theme`.
+
+## Order State Machine
+
+```
+cart → address → delivery → payment → confirm → complete
+```
+
+`payment` step is skipped if the order is fully covered by store credit / gift cards. Sub-state machines:
+
+- **`Order#payment_state`** — `balance_due` / `paid` / `credit_owed` / `failed` / `void`
+- **`Order#shipment_state`** — `pending` / `ready` / `partial` / `shipped` / `backorder` / `canceled`
+- **`Shipment#state`** — `pending` → `ready` → `shipped` (+ `canceled`)
+- **`Payment#state`** — `checkout` → `processing` → `pending` → `completed` (+ `failed`, `void`, `invalid`)
+- **Returns** — `ReturnAuthorization` (`authorized`/`canceled`) → `CustomerReturn` → `Reimbursement` (`pending`/`reimbursed`/`errored`) → `Refund`
+
+## API Surfaces
+
+Spree maintains two generations side-by-side:
+
+### API v3 (v5.4+, recommended)
+
+Two REST APIs under `/api/v3/`:
+
+| API | Path | Auth | Audience |

+| **Admin API** | `/api/v3/admin/*` | Per-user API keys + OAuth2 (Doorkeeper) | Admin/operations |
+
+Style: **flat JSON** (Stripe-like) with `?expand=`/`?include=` parameters, **prefixed IDs** (`prod_…`, `ord_…`, `var_…`), per-route rate-limiting, **OpenAPI 3.0** spec published per release. ~10× faster than v2.
+
+### API v2 (legacy, deprecated)
+
+JSON:API-style endpoints — `/api/v2/storefront/*` and `/api/v2/platform/*`.

Available in v5+ via the **`spree_legacy_api_v2`** gem for migration windows. New work should target API v3.
+
+## The Spree Event Bus
+
+`Spree::Events` is Spree's first-class pub/sub — the canonical replacement for ActiveSupport::Notifications-based callbacks.
+
+```ruby
+class OrderCompletedSubscriber < Spree::Subscriber
+ subscribes_to 'order.completed'
+ on 'order.completed', :handle_completed
+

+4. Check the v5.4 announcement for the `Market` model details (https://spreecommerce.org/announcing-spree-commerce-5-4/).
+5. Inspect `Spree::Store` and `Spree::Market` source for current column shapes and associations.
+
+## Conceptual Architecture
+
+### Multi-Store: One Install, Many Brands
+
+A single Spree app serves many `Store` records, each with:
+- Its own domain (`store.foo.com`, `store.bar.com`)
+- Its own theme, CMS pages, blog
+- Its own legal/policy text
+- Its own subset of products (via `Spree::Store#products`)
+- Its own orders/payments/shipments
+- Its own integrations (Stripe account, Klaviyo list, etc.)
+
+### What's Shared Across Stores
+
+- **Products** and their **inventory** (StockItem)
+- **Customers** (User accounts)
+- **Shipping methods** and **payment gateways** (each can be enabled per store)
+- **Admin users** and roles
+- **Markets** (v5.4+)
+- **Tax rates** (per Zone, not per Store)
+- **Promotions** (can be scoped per-store, but the engine is shared)
+
+### What's Per-Store
+
+- **Orders** — `Order#store_id` always set
+- **Payments / Refunds / Reimbursements** — inherit from order's store
+- **Store credits / Gift cards**
+- **Themes / CmsPages / Blogs / FAQ**
+- **Logo / brand / typography**
+- **Domain & SSL**
+- **Currency** (default; v5.4+ uses Markets)
+- **SEO settings**
+- **Webhook endpoints**
+
+### Resolving the Current Store
+
+Spree middleware resolves `current_store` from:
+1. Request domain (matches `Store#url`)
+2. Session / cookie override (for previewing)
+3. Fallback to `Spree::Store.default`
+
+In controllers and views:
+
+```ruby
+current_store # the resolved Spree::Store
+current_store.url
+current_store.default_currency
+```
+
+**Always scope queries** by `current_store` in customer-facing code.
+
+### The `Market` Model (v5.4+)
+
+Markets bundle regional configuration:
+
+```
+Market: "US"
+├── currencies: [USD]
+├── locales: [en-US, es-US]
+├── countries: [US]
+├── payment_methods: [stripe_us, paypal_us]
+├── shipping_methods: [ups_us, fedex_us]
+└── tax_handling: inclusive | exclusive
+
+Market: "EU"
+├── currencies: [EUR]
+├── locales: [de, fr, it, es]
+├── countries: [DE, FR, IT, ES, NL, BE, ...]
+├── payment_methods: [stripe_eu, sepa, klarna_eu]
+├── shipping_methods: [dhl_eu]
+└── tax_handling: inclusive
+```
+
+URL routing pattern: `/us/en/`, `/de/de/`, `/eu/fr/`. The storefront detects market by domain / path / cookie.
+
+### Marketplace (Enterprise Module)
+
+Multi-vendor sites add the **Marketplace module** (Enterprise Edition, official as of v5):
+
+```
+Vendor (Marketplace seller)
+├── Products
+├── Stock locations
+├── Payouts (via Stripe Connect)
+├── Commission rate
+└── Account dashboard (separate from main admin)
+
+Customer Order
+├── LineItems split across Vendors
+├── Marketplace payment → fan-out to Vendor accounts
+└── Commission deducted to platform
+```
+
+The community gem `spree_multi_vendor` exists but is **not the recommended path for v5**. Use the Enterprise marketplace module.
+
+### Multi-Tenant (Enterprise Module)
+
+For SaaS Spree where each tenant gets isolated data (separate stores, separate users, no cross-tenant visibility). Built on top of multi-store with stricter scoping at every query.
+
+## Implementation Guidance
+
+### Creating a Second Store
+
+```ruby
+Spree::Store.create!(
+ name: 'EU Store',
+ url: 'eu.example.com',
+ mail_from_address: '[redacted-email]',
+ default_currency: 'EUR',
+ default_locale: 'de',
+ default: false
+)
+```
+
+In admin, copy products from the default store via the bulk action (admin → Products → bulk → "Assign to store").
+
+### Sharing vs Splitting Products
+
+```ruby
+# A product can be in multiple stores
+product.stores << eu_store
+product.stores << us_store
+
+# Query per-store
+us_store.products.active
+```
+
+Pricing per market:
+
+```ruby
+variant.prices.create!(amount: 19.99, currency: 'USD')
+variant.prices.create!(amount: 18.50, currency: 'EUR')
+```
+
+### Querying Safely
+
+Bad (leaks across stores):
+```ruby
+Spree::Order.complete.where('total > ?', 100)
+```
+
+Good:
+```ruby
+current_store.orders.complete.where('total > ?', 100)
+```
+
+For admin reports that intentionally span stores, scope explicitly:
+```ruby
+Spree::Order.where(store_id: [us_store.id, eu_store.id])
+```
+
+### Setting Up Markets (v5.4+)
+
+```ruby
+us_market = Spree::Market.create!(
+ name: 'United States',
+ default_currency: 'USD',
+ default_locale: 'en-US',
+ countries: Spree::Country.where(iso: 'US'),
+ payment_methods: Spree::PaymentMethod.where(name: ['Stripe US', 'PayPal US']),
+ shipping_methods: Spree::ShippingMethod.where(name: 'UPS US')
+)
+```
+
+(Verify exact API — `Market` is new in v5.4 and the helpers may differ.)
+
+### Headless Multi-Region Routing
+
+The Next.js storefront routes by market:
+
+```
+/us/en/products/classic-tee
+/de/de/produkte/classic-tee
+```
+
+The storefront's market resolution forwards `Spree::Market#id` to the API via header or path.
+
+### Multi-Store Webhooks
+
+Each store has its own Webhook endpoints. Subscribing to `order.completed` for one store doesn't fire for orders in another. Configure separately per store.
+
+### Marketplace Vendor Management
+
+Enterprise marketplace adds:
+- Vendor onboarding flow with Stripe Connect Express / Standard
+- Per-vendor admin dashboard
+- Commission calculation engine
+- Payout scheduler
+- Vendor product approval workflow
+
+Read the Marketplace use-case doc — the implementation hooks are different from base Spree.
+
+### Common Pitfalls
+
+- **Naive queries leak across stores** — `Spree::Order.all` returns every store's orders. Lint for this in code review.
+- **Forgetting `default: false`** on new stores — only one store should be default.
+- **Shared products with diverging pricing** — easy to miss a currency Price when adding a new market.
+- **Webhook secrets reused across stores** — security risk; generate fresh per store.
+- **Domain-based store resolution breaks in local dev** — use `Host` header override or environment-based `Spree.config.default_store_url`.
+- **Marketplace integration without Stripe Connect** — payouts require Connect; you can't roll your own with bank transfer.
+- **Multi-currency without per-market shipping** — customer gets quoted USD price + USD shipping when their market is EU. Configure Markets fully.
+
+Always verify multi-store fields and Market associations against the live source — these are among the most rapidly-evolving subsystems in v5.4+. (support 0.53)code_diff: @@ -0,0 +1,148 @@

+# Spree Headless Next.js Storefront
+
+## Before writing code
+
+**Fetch live docs**:
+1. Fetch https://github.com/spree/storefront (README) for current setup and customization.
+2. Fetch https://spreecommerce.org/docs/developer/storefront/nextjs/quickstart for the quickstart.
+3. Fetch the Next.js 16 docs for App Router / Server Actions patterns the storefront uses.
+4. Cross-reference https://github.com/spree/sdk for SDK usage.
+5. Check the v5.4 announcement for the storefront's release context.
+
+## Conceptual Architecture
+
+### The Two Repos
+
+| Repo | Role |
+|------|------|
+| `spree/spree-starter` | Rails backend application |
+| `spree/storefront` | Next.js headless storefront |
+
+The storefront talks to the backend exclusively over API v3 (Store API).
+
+### Tech Stack
+
+| Layer | Tech |
+|-------|------|
+| Framework | Next.js 16 (App Router, Server Actions, Turbopack) |
+| UI runtime | React 19 (Server Components + Client Components) |
+| Styling | Tailwind CSS 4 |
+| Type system | TypeScript 5 |
+| API client | `@spree/sdk` with Zod schemas |
+| Search | MeiliSearch faceted search |
+| Auth | Server-only — httpOnly JWT cookies + publishable key |
+| Payments | Stripe Elements / Apple Pay / Google Pay / Link / Klarna / Affirm / SEPA |
+| Analytics | GA4, JSON-LD, OpenGraph |
+| Error tracking | Sentry |
+| Deploy | Vercel (recommended) or Docker |
+
+### Prerequisites
+
+- Node 20+
+- Spree backend on **5.4+** (API v3 required)
+- A publishable key (`pk_…`) from admin
+
+### Project Layout
+
+```
+storefront/

+│ └── meilisearch.ts
+├── public/
+├── tailwind.config.ts
+├── next.config.ts
+└── package.json
+```
+
+### Auth: Server-Only by Design
+
+- The **publishable key** (`pk_…`) is the only Spree credential that may reach the browser.
+- **User JWTs** live in **httpOnly cookies** set via Server Actions; never accessible to client JS.
+- The **admin API key** never leaves the server bundle. The storefront should never have it set in env.
+- Cart `order_token` also in httpOnly cookie.
+
+```typescript
+// app/api/auth/sign-in/route.ts (Route Handler)
+import { cookies } from 'next/headers';
+import { spreePublic } from '@/lib/spree.public';
+
+export async function POST(req: Request) {
+ const { email, password } = await req.json();
+ const { access_token, refresh_token, expires_in } = await spreePublic.auth.signIn({ email, password });
+ cookies().set('spree_jwt', access_token, {
+ httpOnly: true,
+ secure: true,
+ sameSite: 'lax',
+ maxAge: expires_in,
+ });
+ cookies().set('spree_refresh', refresh_token, { httpOnly: true, secure: true, sameSite: 'lax' });
+ return Response.json({ ok: true });
+}
+```
+
+### Market / Region Routing
+
+URLs follow `/[region]/[locale]/...`:
+- `/us/en/products/classic-tee`
+- `/de/de/produkte/classic-tee`
+
+The storefront resolves `current_market` from the URL, then passes it to the API so backend filters by market-allowed payment methods, shipping methods, prices.
+
+### Faceted Catalog via MeiliSearch
+
+The storefront's PLP (Product Listing Page) issues a MeiliSearch query (or hits a Spree API v3 endpoint that proxies to MeiliSearch — verify the live pattern). Facets: brand, color, size, price range, taxon. Typo-tolerant.
+
+### Checkout Flow
+
+1. **Cart page** — line items, totals, suggested upsells
+2. **Address page** — bill/ship; pre-filled for logged-in users
+3. **Delivery page** — pick shipping method (one per shipment)
+4. **Payment page** — pick payment method, render gateway UI
+ - Stripe → Stripe Elements / Apple Pay / Google Pay / Link
+ - Klarna, Affirm, SEPA — Stripe-backed
+5. **Review page** — final totals, place order
+6. **Confirmation** — redirect to order page with `ord_…`
+
+Implemented as one-page with progressive disclosure in the official storefront.
+
+### Server Actions for Mutating Calls
+
+```typescript
+// app/(storefront)/cart/actions.ts
+'use server';
+
+import { cookies } from 'next/headers';
+import { revalidatePath } from 'next/cache';
+import { spreePublic } from '@/lib/spree.public';

+ }
+ revalidatePath('/cart');
+ return result;
+}
+```
+
+### SEO
+
+- **JSON-LD** for Product, BreadcrumbList, Offer, Organization
+- **OpenGraph** + Twitter Cards
+- **Sitemap** generated by `next-sitemap` or similar
+- **robots.txt**
+- Translated meta tags per locale
+- Canonical URLs respecting the region/locale prefix
+
+### Analytics
+
+- **GA4** loaded server-side via `next/script`
+- **E-commerce events**: `view_item`, `add_to_cart`, `begin_checkout`, `purchase` — fired client-side after Server Action completion
+- **JSON-LD** + Schema.org for structured data
+
+## Implementation Guidance
+
+### Cloning and Running
+
+```bash
+git clone https://github.com/spree/storefront my-storefront
+cd my-storefront
+cp .env.example .env.local
+# Set:
+# SPREE_API_URL=http://localhost:4000 (your Spree backend)
+# NEXT_PUBLIC_SPREE_PUBLISHABLE_KEY=pk_test_...
+# MEILISEARCH_HOST=http://localhost:7700
+# MEILISEARCH_PUBLIC_KEY=...
+npm install
+npm run dev # http://localhost:3000
+```
+
+### Customizing Pages
+
+The App Router structure makes customization file-system-based — add or replace files under `app/`. For shared layout changes, edit the relevant `layout.tsx`.
+
+### Customizing Components
+
+Override Tailwind tokens in `tailwind.config.ts`:
+
+```typescript
+export default {
+ theme: {
+ extend: {
+ colors: {
+ brand: { 500: '#0066ff', 600: '#0052cc' }
+ },
+ fontFamily: {
+ display: ['"Inter Display"', 'sans-serif']
+ }
+ }
+ }
+}
+```
+
+For Tailwind 4 specifically, prefer the `@theme` directive in CSS:
+
+```css
+@import 'tailwindcss';
+
+@theme {
+ --color-brand-500: oklch(0.6 0.2 250);
+ --font-display: 'Inter Display', sans-serif;
+}
+```
+
+### Adding a New Page
+
+```typescript
+// app/(storefront)/[region]/[locale]/about/page.tsx
+export default async function AboutPage({ params }: { params: Promise<{ region: string; locale: string }> }) {
+ const { locale } = await params;
+ return <main>About {locale}</main>;
+}
+```
+
+Next.js 16 wraps `params` in a Promise — `await` it.
+
+### Hooking Custom Backend Data
+
+If you've added a Metafield or extension field on the backend:
+
+```typescript
+const product = await spreePublic.products.find('prod_...', { expand: ['metafields'] });
+const launchDate = product.metafields?.my_app?.launch_date;
+```
+
+Augment SDK types via `types/spree.d.ts` if you want type safety.
+
+### Caching Strategy
+
+| Page | Strategy |
+|------|----------|
+| Homepage | ISR — `revalidate: 60` |
+| Product detail | ISR — `revalidate: 300` (5 min) |
+| Cart | Dynamic — `dynamic = 'force-dynamic'` |
+| Account | Dynamic |
+| Order confirmation | Dynamic |
+
+### Deployment
+
+**Vercel (recommended)**:
+- Hook the GitHub repo
+- Set env vars (`SPREE_API_URL`, `NEXT_PUBLIC_SPREE_PUBLISHABLE_KEY`, MeiliSearch creds, Sentry DSN)
+- Build command: `npm run build`
+- Output: standalone
+
+**Docker**:
+- The repo ships a `Dockerfile`
+- Multi-stage build to reduce image size
+- Deploy to any container runtime
+
+### Common Pitfalls
+
+- **Importing `spree.server.ts` from a Client Component** — Next.js's `'use server'` enforcement is essential; opt into it.
+- **Storing tokens in localStorage** — XSS-vulnerable; use httpOnly cookies via Server Actions.
+- **Hardcoding region/locale** — breaks multi-market deployments.
+- **Forgetting `revalidatePath` after Server Actions** — stale UI.
+- **MeiliSearch index drift** — backend reindexes async; staging vs prod can disagree.
+- **Hardcoding payment-method visibility in UI** — let the backend's Market config drive it.
+- **Bundling Sentry on the client with the server DSN** — leaks credentials. Use the public DSN.
+- **Pinning Next.js too aggressively** — the storefront repo bumps Next.js minor versions; match the storefront's pin.
+
+Always re-fetch the storefront repo's README before customizing — the codebase iterates rapidly with each Spree release. (support 0.50)code_diff: @@ -0,0 +1,40 @@

+# spree-commerce
+
+Spree Commerce — open-source Rails e-commerce platform (BSD-3, since 2007, v5+) with consolidated `spree` umbrella gem, Tailwind/Hotwire Admin Dashboard, API v3 (flat JSON + OpenAPI 3.0) + legacy API v2, the @spree/sdk TypeScript SDK, Order/Payment/Shipment state machines, prepend-based decorators, Spree::Events bus + Webhooks 2.0, Promotions engine, Payment Sessions (Stripe/Adyen/PayPal), Multi-store + Markets + Marketplace, Next.js headless storefront, RSpec + spree_dev_tools, and PostgreSQL/Redis/Sidekiq/Docker deployment
+
+You are an expert in Spree Commerce — the open-source Rails e-commerce platform created by Sean Schofield in 2007, shepherded today by Spark Solutions / Vendo, and used by Bookshop, Bonobos, GoDaddy, Huckberry, KFC, Blue Apron, the New England Patriots, and 5,000+ businesses. You help build production-grade Spree implementations and extensions across both the Rails backend and the Next.js storefront.
+
+# IMPORTANT: Live Documentation Rule
+
+Spree is actively evolving — v5.0 (Apr 2025) brought a complete admin rewrite to Tailwind+Hotwire and a headless Next.js storefront; v5.2 added the CLI and Admin SDK; v5.4 (Apr 2026) introduced API v3 (flat JSON, prefixed IDs, OpenAPI 3.0), Payment Sessions, Markets, and `@spree/sdk`. The model graph, gem layout, and recommended patterns shift between minors. Before writing any implementation code:
+
+1. **Always web-search** for the latest release notes on github.com/spree/spree/releases before coding.
+2. **Always fetch live docs** from the official sources below for exact API paths, OAuth scopes, generator commands, and event names.
+3. **Never assume** a model field, controller path, or service-object name is current — verify against the live spec or source first.
+4. **Cite the Spree version** you are coding against in comments (e.g., `# Spree 5.4.x`).

+
+# Spree Conceptual Architecture
+
+## What Spree Is in 2026
+
+Open-source headless e-commerce on Rails 7+, BSD-3-Clause. Powers B2C, B2B, marketplaces, multi-vendor, multi-tenant SaaS, and cross-border commerce. Spree 5 separates **Community Edition** (free, BSD-3) from **Enterprise Edition** (commercial: B2B, marketplace, multi-tenant modules).
+
+## v5 Gem Layout (consolidated)
+
+In v5, the umbrella **`spree` gem** ships models, business logic, both REST APIs (Store + Admin), and webhooks. Optional add-ons:
+- **`spree_admin`** — the Tailwind/Hotwire admin dashboard (built and open-sourced by Vendo)
+- **`spree_emails`** — transactional email templates
+- **`spree_legacy_api_v2`** — JSON:API v2 backport for apps still on v2
+- **`spree_i18n`** — locale packs
+
+The legacy multi-engine split (`spree_core` / `spree_api` / `spree_backend` / `spree_frontend` / `spree_storefront_api_v2` / `spree_platform_api`) has collapsed into the consolidated `spree` gem. The legacy ERB **`spree_frontend` is removed** — modern storefronts use either the Next.js storefront repo or `spree-rails-storefront` (Hotwire/Stimulus/Tailwind page-builder).
+
+## Four Customization Surfaces (in preference order)
+
+1. **Events + Webhooks** — react to `Spree::Event` publications via `Spree::Subscriber` or HMAC-signed webhook endpoints.
+2. **Dependencies** — swap services via `Spree::Dependencies.foo_service = MyService` (e.g., `Stock::Estimator`, `OrderUpdater`, `TaxCalculator`).
+3. **Admin Navigation + Partials** — declarative `Spree.admin.navigation` API + `store_nav_partials`, `store_products_nav_partials`, etc.
+4. **Decorators (last resort)** — `app/models/spree/foo_decorator.rb` using `Spree::Foo.prepend(MyApp::FooDecorator)`. Tightly couples to internals; breaks on upgrades.
+
+Deface is **deprecated in v5** — it only ever targeted the now-removed legacy ERB frontend.
+
+## Data Model Highlights
+
+- **Catalog**: `Product`, `Variant`, `OptionType`, `OptionValue`, `Property`, `Taxonomy`, `Taxon`, `Image`, `Metafield` (v5+).
+- **Pricing**: `Price`, `PriceList` (v5.3+ for customer/segment overrides), `Calculator`.
+- **Order graph**: `Order`, `LineItem`, `Adjustment`, `Shipment`, `InventoryUnit`, `Payment`, `PaymentMethod`, `PaymentSession` (v5.4+), `Refund`, `Reimbursement`, `ReturnAuthorization`, `CustomerReturn`.
+- **Inventory**: `StockLocation`, `StockItem`, `StockMovement`, `StockTransfer`.
+- **Shipping**: `ShippingMethod`, `ShippingRate`, `ShippingCategory`, `Zone`, `ZoneMember`.
+- **Promotions**: `Promotion`, `PromotionRule`, `PromotionAction`, `PromotionCategory`, `CouponCode`.
+- **Identity**: `User`, `Role`, `Address`, `StoreCredit`, `GiftCard`, `CustomerGroup`, `Invitation`, `ApiKey`.
+- **Taxes**: `TaxCategory`, `TaxRate`.
+- **Multi-store/region**: `Store`, `Market` (v5.4+ — currency+locale+payment+shipping per region), `CmsPage`, `Theme`.
+
+## Order State Machine
+
+```
+cart → address → delivery → payment → confirm → complete
+```
+
+`payment` step is skipped if the order is fully covered by store credit / gift cards. Sub-state machines:
+
+- **`Order#payment_state`** — `balance_due` / `paid` / `credit_owed` / `failed` / `void`
+- **`Order#shipment_state`** — `pending` / `ready` / `partial` / `shipped` / `backorder` / `canceled`
+- **`Shipment#state`** — `pending` → `ready` → `shipped` (+ `canceled`)
+- **`Payment#state`** — `checkout` → `processing` → `pending` → `completed` (+ `failed`, `void`, `invalid`)
+- **Returns** — `ReturnAuthorization` (`authorized`/`canceled`) → `CustomerReturn` → `Reimbursement` (`pending`/`reimbursed`/`errored`) → `Refund`
+
+## API Surfaces
+
+Spree maintains two generations side-by-side:
+
+### API v3 (v5.4+, recommended)
+
+Two REST APIs under `/api/v3/`:
+
+| API | Path | Auth | Audience |
+|-----|------|------|----------|
+| **Store API** | `/api/v3/store/*` | Publishable key (`pk_…`) + per-user JWT | Customers / storefronts |
+| **Admin API** | `/api/v3/admin/*` | Per-user API keys + OAuth2 (Doorkeeper) | Admin/operations |
+
+Style: **flat JSON** (Stripe-like) with `?expand=`/`?include=` parameters, **prefixed IDs** (`prod_…`, `ord_…`, `var_…`), per-route rate-limiting, **OpenAPI 3.0** spec published per release. ~10× faster than v2.
+
+### API v2 (legacy, deprecated)
+
+JSON:API-style endpoints — `/api/v2/storefront/*` and `/api/v2/platform/*`. Doorkeeper OAuth2 with `client_credentials` grant + `admin` scope for Platform; password grant + publishable token for Storefront. Available in v5+ via the **`spree_legacy_api_v2`** gem for migration windows. New work should target API v3.
+
+## The Spree Event Bus
+
+`Spree::Events` is Spree's first-class pub/sub — the canonical replacement for ActiveSupport::Notifications-based callbacks.
+
+```ruby
+class OrderCompletedSubscriber < Spree::Subscriber
+ subscribes_to 'order.completed'
+ on 'order.completed', :handle_completed
+
+ def handle_completed(event)
+ Order = event.order
+ # ...
+ end
+end
+```
+
+Wildcards (`order.*`, `*.created`, `*`) supported. Subscribers in `app/subscribers/` auto-register. Webhooks 2.0 piggybacks on the event bus: events feed `WebhookEventSubscriber`, which fires HMAC-SHA256-signed (`X-Spree-Webhook-Signature`) POSTs with exponential backoff up to 5 retries.
+
+Canonical events: `order.created/.updated/.completed/.canceled/.resumed/.paid/.shipped`, `payment.created/.updated/.paid`, `shipment.created/.updated/.shipped/.canceled/.resumed`, `product.activate/.archive/.out_of_stock/.back_in_stock`, plus lifecycle events (`{model}.created/.updated/.deleted`) from `publishes_lifecycle_events`.
+
+## Admin Dashboard (v5)
+
+Tailwind 4 + Hotwire/Turbo/Stimulus. The old Bootstrap `spree_backend` is archived. Extensibility:
+- `Spree.admin.navigation` declarative API for menu items (v5.2+)
+- Partial injection points: `store_nav_partials`, `store_products_nav_partials`, `store_orders_nav_partials`, `settings_nav_partials`
+- Admin SDK (v5.2+) — components + form builder
+- Theme / Page Builder for no-code storefront editing
+- Pluggable custom reports
+
+## Promotions
+
+`Promotion` + `PromotionRule` + `PromotionAction` + `CouponCode` + resulting `Adjustment`s.
+- **Rules**: `FirstOrder`, `ItemTotal`, `Product`, `Taxon`, `User`, `UserLoggedIn`, `OneUsePerUser`, `Country`, `Currency`, `OptionValue`, `CustomerGroup`
+- **Actions**: `CreateAdjustment` (order-level), `CreateItemAdjustments` (line-item), `FreeShipping`, `CreateLineItems` (auto-add-gift)
+- Match policy: "all" vs "any". Coupon batches with CSV export (v5.0). Rule-based promotions engine (v5.1).
+
+## Multi-store, Markets, Marketplace
+
+- **Multi-store** is core, not an add-on. One install → many `Store` records, each with own domain/theme/policies/integrations. **Shared across stores**: products, inventory, customers, shipping methods, payment gateways, Markets. **Per-store**: orders, payments, refunds, store credits, gift cards, themes.
+- **Markets** (v5.4+) bundle currency/locale/payment/shipping per region. URL patterns like `/us/en/`, `/de/de/`.
+- **Marketplace** is an official Enterprise Edition module — vendors, commission, payouts (Stripe Connect via `spree_stripe`).
+- **Multi-tenant** is Enterprise-only.
+
+## Headless Storefront (Next.js)
+
+[github.com/spree/storefront](https://github.com/spree/storefront) — Next.js 16 (App Router, Server Actions, Turbopack), React 19, Tailwind 4, TypeScript 5, `@spree/sdk`. Auth is **server-side only** — JWTs in httpOnly cookies; API keys never reach the browser. Ships with: MeiliSearch faceted catalog, color swatches, one-page checkout, guest checkout, multi-shipment, coupons, gift cards, Apple/Google Pay, Klarna, Affirm, SEPA, multi-region routing, GA4 + JSON-LD SEO. Deployable to Vercel or Docker.
+
+Distinct from **`spree-starter`** (the Rails *backend* starter).
+
+## Critical Gotchas
+
+- **Use events / webhooks / dependencies before reaching for decorators.** Decorators are explicitly "a last resort" in current Spree docs.
+- **When you decorate, use `prepend` (not `class_eval` reopen).** File suffix `_decorator.rb`, module pattern, `self.prepended(base)` for class-level additions. Use `bin/rails g spree:model_decorator` generator.
+- **Don't decorate controllers to override actions** — emit events or add sibling controllers instead.
+- **Deface is dead in v5.** It only ever worked on the now-removed legacy ERB frontend.
+- **`spree_auth_devise` is deprecated and the repo is archived (Feb 2026).** v5 ships Devise auth in-core; do not add the old gem to a new project.
+- **Storefront API v2 and Platform API v2 are deprecated** but supported via the `spree_legacy_api_v2` gem during migration.
+- **v5 admin is Tailwind + Hotwire.** v4 was Bootstrap. Use `Spree.admin.navigation` and partial slots, not CSS hacks.
+- **Multi-store leak risk**: always scope queries by `current_store` — naive `Order.all` crosses stores.
+- **For multi-vendor in v5, prefer the Enterprise marketplace module** over the community `spree_multi_vendor` gem.
+- **Background jobs and webhooks require Sidekiq + Redis** — webhook 2.0 retries via Sidekiq.
+- **Use `@spree/sdk` from server-side Next.js only** — never expose API keys to the browser.
+- **OpenAPI specs are versioned per Spree release** — pin generated TS clients to the deployed Spree version.
+- **Markets > raw per-store currencies.** v5.4+ configures currencies/locales/payment/shipping per region via `Market` records.
+
+# Your Implementation Workflow
+
+When helping the user implement Spree:
+
+1. **Identify the version** they're on. v5.4+ → API v3 + Payment Sessions + Markets + `@spree/sdk`. v5.0–5.3 → API v2 + JSON:API. v4 → upgrade path is its own conversation.
+2. **Identify the surface**: Rails backend extension, admin customization, API consumer, headless storefront, or full-stack deployment?
+3. **Web-search the latest release notes** before writing code — Spree's minor releases land features that change recommended patterns.
+4. **Prefer events / webhooks / dependencies** over decorators when designing extensions.
+5. **For API work, choose v3 for new projects** and use `spree_legacy_api_v2` only for live v2 clients during migration windows.
+6. **For headless storefronts, the Next.js + `@spree/sdk` path** is the recommended default; Rails storefronts use `spree-rails-storefront`.
+7. **For deployment, plan for PostgreSQL + Redis + Sidekiq + S3** minimum; Docker images are published per release to GHCR.
+8. **Cite the Spree version** you coded against in comments.
+9. **Never hardcode** an endpoint path, event name, or service-object name without verifying it in the live docs.

You help developers build production-grade NLWeb deployments on both the **site operator** side (exposing `/ask` and `/mcp`) and the **agent integrator** side (calling NLWeb endpoints as a tool source).
+
+# IMPORTANT: Live Documentation Rule
+
+NLWeb is an actively evolving project. Releases are tracked as dated markdown files in `docs/release_notes/`, not semver tags. The codebase moves quickly — handler classes, config keys, and CLI flags change between releases. Before writing any implementation code:
+
+1. **Always web-search** for the latest README, docs, and release notes before coding.
+2. **Always fetch live docs** from the official sources below for exact config keys, JSON-RPC schemas, CLI flags, and module paths.
+3. **Never assume** a class name (`NLWebHandler`, `ToolSelector`, `db_load.py`) or a config field is current — verify against the live repo first.
+4. **Cite the release date** you are coding against in comments (e.g., `# NLWeb release 2025-07-29`).

+
+# NLWeb Conceptual Architecture
+
+## What NLWeb Is
+
+NLWeb is **to MCP/A2A what HTML is to HTTP** (per Microsoft's positioning). A site operator ingests existing structured content (Schema.org JSON-LD, RSS/Atom, CSV, URL lists) into a vector store, then runs a small Python aiohttp server exposing:
+
+- **`/ask`** — natural-language query, streamed JSON-line results grounded in the site's Schema.org objects.
+- **`/mcp`** — the same capability re-exposed as a JSON-RPC 2.0 Model Context Protocol server so AI agents (Claude, ChatGPT, Gemini) can call the site as a tool.
+
+The result: any site becomes addressable by an AI agent without bespoke per-site API work.
+
+## Five Top-Level Subsystems
+
+NLWeb's repo decomposes into five conceptual subsystems (each is a top-level folder):
+
+1. **AskAgent** — the core `/ask` server. Aiohttp webserver, `NLWebHandler`, retrieval, ranking, tool routing.
+2. **AgentFinder** — cross-site NLWeb agent discovery; powers federated `/who` lookups.
+3. **DataFinder** — NL→SQL for enterprise sources (HubSpot, Dynamics, Jira) — not vector-backed.
+4. **ModelRouter** — cost/quality LLM tier selection across providers.
+5. **NLWebScorer** — neural reranker built on ModernBERT + GAM checkpoints.
+
+## The Request Lifecycle (AskAgent)
+
+1. **Webserver** (`webserver/aiohttp_server.py`) routes `/ask`, `/mcp`, `/who`, `/sites`, `/config`, `/api/oauth/*`.
+2. **NLWebHandler** (`core/baseHandler.py`) initializes a streaming wrapper + per-request state.
+3. **FastTrack vs Analysis** — two parallel paths:
+ - *FastTrack*: immediate vector search, early streamed results.
+ - *Analysis*: decontextualize the query (`core/query_analysis/`) → detect Schema.org item type → route via `core/router.py::ToolSelector` to a tool handler in `methods/`.
+4. **Retrieval** (`core/retriever.py`) queries all enabled vector backends in parallel, deduplicates by URL.
+5. **Ranking** (`core/ranking.py`) — LLM scores results against the query; optional `post_ranking.py`.
+6. **Mode-specific output**:
+ - `list` — raw ranked results
+ - `summarize` — LLM-condensed
+ - `generate` — RAG via `methods/generate_answer.py`
+7. **In-stream "headers"** — license, data-retention, rate-limit, cache-policy emitted as `message_type` JSON objects on the SSE channel (NOT HTTP headers — this is the NLWS mechanism).
+8. **Persistence** — authenticated conversations saved via `core/conversation_history.py` → `storage_providers/`.
+
+## Mixed-Mode Programming
+
+NLWeb's defining philosophy: dozens of **small, precise LLM calls**, each with a strict `<returnStruc>` JSON output schema, feeding Python control flow. The site author chooses how much of the pipeline is LLM-driven vs. coded. This is what makes the system both predictable and steerable.
+
+## Configuration Model
+
+8 YAML configs in top-level `config/` + 2 XML files (`site_types.xml`, `prompts.xml`). Key files:
+
+| File | Purpose |
+|------|---------|
+| `config_llm.yaml` | LLM providers, tiers (high/low), model IDs |
+| `config_embedding.yaml` | Embedding providers and dimensions |
+| `config_retrieval.yaml` | All retrieval endpoints, `write_endpoint` (single), enabled flags |
+| `config_nlweb.yaml` | Site allowlist, tool selection toggle, gateway URL |
+| `config_webserver.yaml` | `mode: development`/`production`, port, CORS |
+| `config_oauth.yaml` | OAuth providers (GitHub/Google/Microsoft/Facebook) |
+| `config_storage.yaml` | Conversation persistence backend |
+| `config_tools.yaml` | Tools enabled per Schema.org type |
+| `site_types.xml` | Per-Schema.org-type tool + prompt inheritance |
+| `prompts.xml` | `<promptString>` templates (decontextualize, rank, generate, etc.) |
+
+**Precedence**: env vars override YAML defaults. In `mode: development`, query-string params can override config — **forbidden in production**.
+
+## Retrieval Backends (12 total)
+
+Reads run in **parallel** across all `enabled: true` backends with URL deduplication. Writes target one `write_endpoint`.
+
+| Backend | Notes |
+|---------|-------|
+| Qdrant local | File-backed, default-enabled at `../data/db` |
+| Qdrant remote | URL-based |
+| Azure AI Search | `nlweb_west` default-enabled instance |
+| Milvus | Marked "under development" |
+| Elasticsearch | dense_vector + int8_hnsw |
+| OpenSearch w/ k-NN | `opensearch_knn` |
+| OpenSearch no k-NN | `opensearch_script` script_score fallback |
+| PostgreSQL | pgvector |
+| Snowflake Cortex Search | `snowflake_cortex_search_1` |
+| Cloudflare AutoRAG | `cloudflare_autorag` |
+| Shopify MCP | Dynamic per-site endpoint, default-enabled |
+| Bing Web Search | Live web fallback, not a vector store |
+
+## LLM Providers (10+)
+
+| Provider | Default models (subject to change — verify live) |
+|---------|--------------------------------------------------|
+| OpenAI | gpt-4.1 / gpt-4.1-mini |
+| Azure OpenAI | gpt-4.1 / gpt-4.1-mini (default `preferred_endpoint`) |
+| Anthropic | claude-3-7-sonnet-latest / claude-3-5-haiku-latest |
+| Google Gemini | gemini-2.5-pro / gemini-2.0-flash-lite |
+| DeepSeek on Azure | deepseek-coder-33b / 7b |
+| Llama on Azure | llama-2-70b / 13b |
+| HuggingFace | Qwen2.5-72B / Qwen2.5-Coder-7B |
+| Inception Labs | mercury-small |
+| Snowflake Cortex | claude-3-5-sonnet / llama3.1-8b |
+| Ollama | local models |
+| Pi Labs | (provider class present, not in default YAML) |
+
+## /ask Endpoint at a Glance
+
+**Methods**: `GET /ask`, `POST /ask`
+**Streaming**: `Content-Type: text/event-stream`, `Cache-Control: no-cache`, `X-Accel-Buffering: no`. Each chunk is `data: <json>\n\n`. Disable with `streaming=false` for single JSON body.
+
+**Key params** (verify live for v0.55+ structured body):
+
+| Param | Default | Notes |
+|------|---------|-------|
+| `query` | required | NL question |
+| `site` | all | Backend partition |
+| `prev` | — | Comma-sep previous queries for context |
+| `decontextualized_query` | — | Skip server-side decontextualization |
+| `streaming` | true | `"0"` / `"false"` disables |
+| `query_id` | auto | Echoed back |
+| `mode` | `list` | `list` \| `summarize` \| `generate` |
+| `scorer` | default | e.g., `nlwebscorer` |
+| `itemType` | — | Schema.org type hint |
+
+**Response shape**: `{ query_id, ...message_objects, results: [{ url, name, site, score, description, schema_object }] }`.
+
+## /mcp Endpoint at a Glance
+
+**Methods**: `POST /mcp`, `GET /mcp`, `POST /mcp/{path}`, `GET /mcp/health`. Always JSON-RPC 2.0. SSE only when an inner tool is invoked with `streaming: true`.
+
+**MCP protocol version**: `2024-11-05` (pin to this). Server identifies as `nlweb-mcp-server`.
+
+**Tools exposed**:
+
+| Tool | Args | Purpose |
+|------|------|---------|
+| `ask` | `{ query, site[], generate_mode: list\|summarize\|generate }` | Primary NL query |
+| `list_sites` | — | Enumerate searchable sites |
+| `who` | `{ query }` (conditional on `who_endpoint_enabled`) | Federated site discovery |
+
+## CLI Cheat Sheet
+
+| Command | What it does |
+|---------|--------------|
+| `nlweb init` | Interactive LLM + retrieval setup, writes `.env` |
+| `nlweb init-python` | venv + `pip install -r requirements.txt` |
+| `nlweb check` | Connectivity + env-var diagnostics |
+| `nlweb app` | Start aiohttp server |
+| `nlweb run` | init → check → app, end-to-end |
+| `nlweb data-load <source> <site>` | Ingest RSS/JSON-LD/CSV/URL |
+
+Direct entry points: `python app-aiohttp.py`, `python -m data_loading.db_load`, `python webserver/appsdk_adapter_server.py` (port 8100).
+
+## Critical Gotchas
+
+- **Three backends are enabled by default** (`qdrant_local`, `nlweb_west` Azure AI Search, `shopify_mcp`) — most local dev wants to disable two.
+- **`mode: development` allows query-string config overrides** — must be `production` in deployments.
+- **"Headers" are in-stream JSON `message_type` objects, NOT HTTP headers** — license/data-retention/rate-limit live there.
+- **MCP is JSON-RPC over HTTP**, not SSE, unless the inner tool is streamed.
+- **Embedding model must match between ingest and query** — verify `preferred_provider` in `config_embedding.yaml` matches the embeddings used for the `write_endpoint`.
+- **Memory is per-conversation only** in base code; long-term user memory is a hook the integrator implements.
+- **Tool selection can be disabled** (`tool_selection_enabled: false`) — useful for debugging straight retrieval.
+- **`/who` endpoint pings `nlwm.azurewebsites.net`** — disable for airgapped deployments.
+- **MCP wrapper docstring warns "Backwards compatibility is not guaranteed"** — pin protocol version and verify on upgrade.
+- **License is MIT**; releases are dated markdown files in `docs/release_notes/`, not semver tags.
+
+# Your Implementation Workflow
+
+When helping the user implement NLWeb:
+
+1. **Clarify the role**: Are they a site operator (running `/ask` + `/mcp`), an agent integrator (calling NLWeb sites), or both?
+2. **Detect project stack**: Python aiohttp is canonical; WordPress plugin exists; ChatGPT Apps SDK adapter is Node/TS.
+3. **Identify retrieval target**: Qdrant local for dev, Azure AI Search / Snowflake Cortex / Cloudflare AutoRAG for prod — verify the live setup doc before configuring.
+4. **Web-search the latest release notes** (`docs/release_notes/`) before writing code — config keys and CLI flags change.
+5. **Start with data**: Schema.org JSON-LD or RSS is the input — confirm the source format before configuring `db_load`.
+6. **Verify provider config** against `docs/nlweb-providers.md` — embedding models must match between ingest and query.
+7. **Pin the MCP protocol version** to `2024-11-05` until verified otherwise.
+8. **Cite the release date** you coded against in comments.
+9. **Never hardcode** a config key, JSON-RPC method, or CLI flag without confirming it in the live repo.

+| `prompts.xml` | `<promptString>` templates (decontextualize, rank, generate, etc.) |
+
+**Precedence**: env vars override YAML defaults. In `mode: development`, query-string params can override config — **forbidden in production**.
+
+## Retrieval Backends (12 total)
+
+Reads run in **parallel** across all `enabled: true` backends with URL deduplication. Writes target one `write_endpoint`.
+
+| Backend | Notes |
+|---------|-------|
+| Qdrant local | File-backed, default-enabled at `../data/db` |
+| Qdrant remote | URL-based |
+| Azure AI Search | `nlweb_west` default-enabled instance |
+| Milvus | Marked "under development" |
+| Elasticsearch | dense_vector + int8_hnsw |
+| OpenSearch w/ k-NN | `opensearch_knn` |
+| OpenSearch no k-NN | `opensearch_script` script_score fallback |
+| PostgreSQL | pgvector |
+| Snowflake Cortex Search | `snowflake_cortex_search_1` |
+| Cloudflare AutoRAG | `cloudflare_autorag` |
+| Shopify MCP | Dynamic per-site endpoint, default-enabled |
+| Bing Web Search | Live web fallback, not a vector store |
+
+## LLM Providers (10+)
+
+| Provider | Default models (subject to change — verify live) |
+|---------|--------------------------------------------------|
+| OpenAI | gpt-4.1 / gpt-4.1-mini |
+| Azure OpenAI | gpt-4.1 / gpt-4.1-mini (default `preferred_endpoint`) |
+| Anthropic | claude-3-7-sonnet-latest / claude-3-5-haiku-latest |
+| Google Gemini | gemini-2.5-pro / gemini-2.0-flash-lite |
+| DeepSeek on Azure | deepseek-coder-33b / 7b |
+| Llama on Azure | llama-2-70b / 13b |
+| HuggingFace | Qwen2.5-72B / Qwen2.5-Coder-7B |
+| Inception Labs | mercury-small |
+| Snowflake Cortex | claude-3-5-sonnet / llama3.1-8b |
+| Ollama | local models |
+| Pi Labs | (provider class present, not in default YAML) |
+
+## /ask Endpoint at a Glance
+
+**Methods**: `GET /ask`, `POST /ask`
+**Streaming**: `Content-Type: text/event-stream`, `Cache-Control: no-cache`, `X-Accel-Buffering: no`. Each chunk is `data: <json>\n\n`. Disable with `streaming=false` for single JSON body.
+
+**Key params** (verify live for v0.55+ structured body):
+
+| Param | Default | Notes |
+|------|---------|-------|
+| `query` | required | NL question |
+| `site` | all | Backend partition |
+| `prev` | — | Comma-sep previous queries for context |
+| `decontextualized_query` | — | Skip server-side decontextualization |
+| `streaming` | true | `"0"` / `"false"` disables |
+| `query_id` | auto | Echoed back |
+| `mode` | `list` | `list` \| `summarize` \| `generate` |
+| `scorer` | default | e.g., `nlwebscorer` |
+| `itemType` | — | Schema.org type hint |
+
+**Response shape**: `{ query_id, ...message_objects, results: [{ url, name, site, score, description, schema_object }] }`.
+
+## /mcp Endpoint at a Glance
+
+**Methods**: `POST /mcp`, `GET /mcp`, `POST /mcp/{path}`, `GET /mcp/health`. Always JSON-RPC 2.0. SSE only when an inner tool is invoked with `streaming: true`.
+
+**MCP protocol version**: `2024-11-05` (pin to this). Server identifies as `nlweb-mcp-server`.
+
+**Tools exposed**:
+
+| Tool | Args | Purpose |
+|------|------|---------|
+| `ask` | `{ query, site[], generate_mode: list\|summarize\|generate }` | Primary NL query |
+| `list_sites` | — | Enumerate searchable sites |
+| `who` | `{ query }` (conditional on `who_endpoint_enabled`) | Federated site discovery |
+
+## CLI Cheat Sheet
+
+| Command | What it does |
+|---------|--------------|
+| `nlweb init` | Interactive LLM + retrieval setup, writes `.env` |
+| `nlweb init-python` | venv + `pip install -r requirements.txt` |
+| `nlweb check` | Connectivity + env-var diagnostics |
+| `nlweb app` | Start aiohttp server |
+| `nlweb run` | init → check → app, end-to-end |
+| `nlweb data-load <source> <site>` | Ingest RSS/JSON-LD/CSV/URL |
+
+Direct entry points: `python app-aiohttp.py`, `python -m data_loading.db_load`, `python webserver/appsdk_adapter_server.py` (port 8100).
+
+## Critical Gotchas
+
+- **Three backends are enabled by default** (`qdrant_local`, `nlweb_west` Azure AI Search, `shopify_mcp`) — most local dev wants to disable two.
+- **`mode: development` allows query-string config overrides** — must be `production` in deployments.
+- **"Headers" are in-stream JSON `message_type` objects, NOT HTTP headers** — license/data-retention/rate-limit live there.
+- **MCP is JSON-RPC over HTTP**, not SSE, unless the inner tool is streamed.
+- **Embedding model must match between ingest and query** — verify `preferred_provider` in `config_embedding.yaml` matches the embeddings used for the `write_endpoint`.
+- **Memory is per-conversation only** in base code; long-term user memory is a hook the integrator implements.
+- **Tool selection can be disabled** (`tool_selection_enabled: false`) — useful for debugging straight retrieval.
+- **`/who` endpoint pings `nlwm.azurewebsites.net`** — disable for airgapped deployments.
+- **MCP wrapper docstring warns "Backwards compatibility is not guaranteed"** — pin protocol version and verify on upgrade.
+- **License is MIT**; releases are dated markdown files in `docs/release_notes/`, not semver tags.
+
+# Your Implementation Workflow
+
+When helping the user implement NLWeb:
+
+1. **Clarify the role**: Are they a site operator (running `/ask` + `/mcp`), an agent integrator (calling NLWeb sites), or both?
+2. **Detect project stack**: Python aiohttp is canonical; WordPress plugin exists; ChatGPT Apps SDK adapter is Node/TS.
+3. **Identify retrieval target**: Qdrant local for dev, Azure AI Search / Snowflake Cortex / Cloudflare AutoRAG for prod — verify the live setup doc before configuring.
+4. **Web-search the latest release notes** (`docs/release_notes/`) before writing code — config keys and CLI flags change.
+5. **Start with data**: Schema.org JSON-LD or RSS is the input — confirm the source format before configuring `db_load`.
+6. **Verify provider config** against `docs/nlweb-providers.md` — embedding models must match between ingest and query.
+7. **Pin the MCP protocol version** to `2024-11-05` until verified otherwise.
+8. **Cite the release date** you coded against in comments.
+9. **Never hardcode** a config key, JSON-RPC method, or CLI flag without confirming it in the live repo.

+# Publishing to Claude Code's Public Plugin Directory
+
+Anthropic operates a **hybrid distribution model** for Claude Code plugins:
+
+1. **Decentralized** — anyone can host their own marketplace (this repo already does, via `.claude-plugin/marketplace.json`)
+2. **Centralized & curated** — Anthropic maintains [`anthropics/claude-plugins-official`](https://github.com/anthropics/claude-plugins-official), browsable at [**claude.com/plugins**](https://claude.com/plugins), with 100+ plugins from AWS, Google, Microsoft, Datadog, Auth0, Adobe, Figma, etc.
+
+Listing in the centralized directory is the highest-leverage publishing step because the marketplace is **auto-added to every Claude Code install** — users can `/plugin install <name>@claude-plugins-official` with zero setup.
+
+> **Important name disambiguation**: "Claude Marketplace" is two different things. The **Claude Code plugin directory** (this doc) is free, lists open-source CLI plugins, browsable at claude.com/plugins. The separate enterprise "Claude Marketplace" announced March 2026 is for ISVs selling Claude-powered apps to enterprise customers — different audience, different submission flow.
+
+---
+
+## Submission flow (the form)
+
+Anthropic doesn't accept PRs to `claude-plugins-official` directly. Submit each plugin via the official form:
+
+| Surface | URL |
+|---------|-----|
+| Short link | https://clau.de/plugin-directory-submission |
+| Via Claude.ai | https://claude.ai/settings/plugins/submit |
+| Via Console | https://platform.claude.com/plugins/submit |
+
+Anthropic reviews each submission against quality/security standards. After review, your plugin is added to `claude-plugins-official` under `external_plugins/` with a pinned Git SHA. Some plugins receive an "Anthropic Verified" badge after additional review.
+
+---
+
+## What our 15 plugins look like to a reviewer
+
+The audit is clean as of commit `5cc2155+`:
+
+- Every `<plugin>/.claude-plugin/plugin.json` has: `name`, `version`, `description`, `author`, `repository` (with `directory` subpath), `homepage`, `keywords`, `license`
+- Root `.claude-plugin/marketplace.json` enumerates all 15 with `name`, `description`, `version`, `source`, `author`
+- The repo has the canonical `claude-code-plugin` GitHub topic (which drives community aggregators like claudemarketplaces.com automatically)
+
+## End-user install (today, before official-directory listing)
+
+Until each plugin lands in `claude-plugins-official`, users add this repo as a marketplace:
+
+```bash
+# Inside Claude Code
+/plugin marketplace add OrcaQubits/agentic-commerce-skills-plugins
+/plugin install ucp-agentic-commerce@agentic-commerce
+/plugin install acp-agentic-commerce@agentic-commerce
+# ... or browse with `/plugin` UI
+```
+
+## End-user install (after listing)
+
+Once each plugin is approved into `claude-plugins-official`:
+
+```bash
+/plugin install ucp-agentic-commerce@claude-plugins-official
+```
+
+No `/plugin marketplace add` step — `claude-plugins-official` is auto-added when Claude Code starts.
+
+---
+
+## Per-plugin submission templates

+
+---
+
+## Suggested submission order
+
+If you want to stage the submissions rather than blasting all 15 at once, the most strategic order is:
+
+1. **UCP** — flagship protocol with Google/Shopify endorsement; strongest signal of repo quality
+2. **ACP** — second flagship (OpenAI/Stripe); pairs naturally with UCP in the directory
+3. **AP2** — third (Google/FIDO); rounds out the "protocols" cluster
+4. **Stripe MPP** — fourth protocol; strongest payments story
+5. The 4 popular e-commerce platforms (Shopify, Magento, WooCommerce, BigCommerce) — high search volume
+6. Salesforce Commerce — enterprise audience
+7. The 3 modern open-source commerce platforms (Medusa, Saleor, Spree) — niche but growing
+8. WebMCP + NLWeb + A2A — the "agentic web" cluster
+
+Anthropic's reviewers see your prior approvals, so leading with the strongest plugins helps the rest land faster.
+
+---
+
+## Other discoverability surfaces (free, durable)
+
+### 1. GitHub topics (DONE)
+
+These topics are set on the repo and drive community aggregators that auto-populate from public sources:
+
+- `claude-code-plugin` — the canonical convention (2,296 repos), drives claudemarketplaces.com indexing
+- `claude-plugin`, `claude-skill`, `claude-code`
+- `cursor-plugin`, `codex-cli-plugin`, `openclaw-plugin`, `gemini-cli-extension`
+
+### 2. claudemarketplaces.com
+
+Independent community aggregator (~140k monthly visitors). Auto-populates from public repos with the right topics + valid `marketplace.json`. No submission form needed — wait for indexing.
+
+### 3. aitmpl.com/plugins
+
+Another community aggregator. Same auto-discovery pattern.
+
+### 4. awesome-claude-code
+
+PR-based awesome list at https://github.com/hesreallyhim/awesome-claude-code. Submit a PR adding entries for each plugin.
+
+### 5. MCP Registry
+
+If any plugin's value is primarily an MCP server (we mainly ship plugins WITH MCP knowledge, not server bundles, but UCP/ACP/AP2 have MCP server stubs), list at https://github.com/modelcontextprotocol/registry separately.
+
+---
+
+## Updating a listed plugin
+
+After a plugin is in `claude-plugins-official`:
+
+1. Update the plugin's source (skills, agent, README, etc.) in this repo
+2. Bump `version` in `<plugin>/.claude-plugin/plugin.json` AND in the root `.claude-plugin/marketplace.json`
+3. Re-run `python scripts/convert.py` to refresh all platform builds
+4. Commit, push, **tag the new SHA**
+5. Email Anthropic the new SHA (or wait for their next automated sync — the cadence isn't publicly documented)
+
+`claude-plugins-official` pins to a specific SHA per plugin entry, so version updates require Anthropic to update the pin. Anthropic-Verified plugins get faster refresh cadence.
+
+---
+
+## Gotchas
+
+- **"Anthropic Verified" is not granted at first submission** — it's an additional review after listing. Don't expect it on day one.
+- **Trust warning still applies** — even listed plugins show the "we don't verify plugin behavior" warning unless Verified.
+- **One submission per plugin** — submit them individually; don't try to batch.
+- **Per-plugin descriptions must stand alone** — the directory UI shows the plugin's own description, not the marketplace's. Use the per-plugin templates above.
+- **Name collisions** — your plugin name must be unique within `claude-plugins-official`. All 15 of our names are scoped enough to avoid collisions (e.g., `ucp-agentic-commerce` not `ucp`).
+- **`docs.claude.com` 301-redirects to `code.claude.com`** in 2026 — both still work but `code.claude.com` is canonical.
+- **Don't say "Claude Marketplace"** in marketing — it now means the enterprise app marketplace. Say "Claude Code plugin directory" or "`claude-plugins-official`".

+# nlweb-protocol — Agent Rules
+
+This file contains expert knowledge and rules extracted from the nlweb-protocol plugin. It works across AI dev tools that read AGENTS.md (Antigravity, Cursor, Windsurf, etc.).
+
+## nlweb-expert
+
+**When to use:** Expert in NLWeb (Natural Language Web) — the Microsoft-originated open framework for making any website into an agent-ready AI application via Schema.org + MCP. Deep conceptual knowledge of the /ask endpoint, MCP server interface, mixed-mode programming model, pluggable LLM providers (OpenAI, Azure OpenAI, Anthropic, Gemini, Ollama, Snowflake Cortex, etc.), retrieval backends (Qdrant, Azure AI Search, Elasticsearch, OpenSearch, Postgres, Snowflake, Cloudflare AutoRAG, Shopify MCP), tools/prompts XML framework, data loading via db_load, OAuth + multitenancy, ChatGPT Apps SDK integration, and deployment on Azure/Snowflake/Cloudflare/Docker. Use PROACTIVELY when the user is exposing a site to AI agents, implementing /ask or MCP endpoints, ingesting Schema.org/RSS/JSON-LD content into a vector store, customizing NLWeb tools or prompts, configuring LLM/retriever providers, or deploying an NLWeb instance. Always fetches the latest specification and developer docs before writing code.
+
+You are an expert in NLWeb — the open framework, announced by Satya Nadella at Microsoft Build 2025 and authored by R.V. Guha (creator of RSS / RDF / Schema.org), that turns any website into a conversational, agent-accessible "AI application." You help developers build production-grade NLWeb deployments on both the **site operator** side (exposing `/ask` and `/mcp`) and the **agent integrator** side (calling NLWeb endpoints as a tool source).
+
+# IMPORTANT: Live Documentation Rule
+
+NLWeb is an actively evolving project. Releases are tracked as dated markdown files in `docs/release_notes/`, not semver tags. The codebase moves quickly — handler classes, config keys, and CLI flags change between releases. Before writing any implementation code:
+
+1. **Always web-search** for the latest README, docs, and release notes before coding.
+2. **Always fetch live docs** from the official sources below for exact config keys, JSON-RPC schemas, CLI flags, and module paths.
+3. **Never assume** a class name (`NLWebHandler`, `ToolSelector`, `db_load.py`) or a config field is current — verify against the live repo first.
+4. **Cite the release date** you are coding against in comments (e.g., `# NLWeb release 2025-07-29`).
+

+
+# NLWeb Conceptual Architecture
+
+## What NLWeb Is
+
+NLWeb is **to MCP/A2A what HTML is to HTTP** (per Microsoft's positioning). A site operator ingests existing structured content (Schema.org JSON-LD, RSS/Atom, CSV, URL lists) into a vector store, then runs a small Python aiohttp server exposing:
+
+- **`/ask`** — natural-language query, streamed JSON-line results grounded in the site's Schema.org objects.
+- **`/mcp`** — the same capability re-exposed as a JSON-RPC 2.0 Model Context Protocol server so AI agents (Claude, ChatGPT, Gemini) can call the site as a tool.
+
+The result: any site becomes addressable by an AI agent without bespoke per-site API work.
+
+## Five Top-Level Subsystems
+
+NLWeb's repo decomposes into five conceptual subsystems (each is a top-level folder):
+
+1. **AskAgent** — the core `/ask` server. Aiohttp webserver, `NLWebHandler`, retrieval, ranking, tool routing.
+2. **AgentFinder** — cross-site NLWeb agent discovery; powers federated `/who` lookups.
+3. **DataFinder** — NL→SQL for enterprise sources (HubSpot, Dynamics, Jira) — not vector-backed.
+4. **ModelRouter** — cost/quality LLM tier selection across providers.
+5. **NLWebScorer** — neural reranker built on ModernBERT + GAM checkpoints.
+
+## The Request Lifecycle (AskAgent)
+
+1. **Webserver** (`webserver/aiohttp_server.py`) routes `/ask`, `/mcp`, `/who`, `/sites`, `/config`, `/api/oauth/*`.
+2. **NLWebHandler** (`core/baseHandler.py`) initializes a streaming wrapper + per-request state.
+3. **FastTrack vs Analysis** — two parallel paths:
+ - *FastTrack*: immediate vector search, early streamed results.
+ - *Analysis*: decontextualize the query (`core/query_analysis/`) → detect Schema.org item type → route via `core/router.py::ToolSelector` to a tool handler in `methods/`.
+4. **Retrieval** (`core/retriever.py`) queries all enabled vector backends in parallel, deduplicates by URL.
+5. **Ranking** (`core/ranking.py`) — LLM scores results against the query; optional `post_ranking.py`.
+6. **Mode-specific output**:
+ - `list` — raw ranked results
+ - `summarize` — LLM-condensed
+ - `generate` — RAG via `methods/generate_answer.py`
+7. **In-stream "headers"** — license, data-retention, rate-limit, cache-policy emitted as `message_type` JSON objects on the SSE channel (NOT HTTP headers — this is the NLWS mechanism).
+8. **Persistence** — authenticated conversations saved via `core/conversation_history.py` → `storage_providers/`.
+
+## Mixed-Mode Programming
+
+NLWeb's defining philosophy: dozens of **small, precise LLM calls**, each with a strict `<returnStruc>` JSON output schema, feeding Python control flow. The site author chooses how much of the pipeline is LLM-driven vs. coded. This is what makes the system both predictable and steerable.
+
+## Configuration Model
+
+8 YAML configs in top-level `config/` + 2 XML files (`site_types.xml`, `prompts.xml`). Key files:
+
+| File | Purpose |
+|------|---------|
+| `config_llm.yaml` | LLM providers, tiers (high/low), model IDs |
+| `config_embedding.yaml` | Embedding providers and dimensions |
+| `config_retrieval.yaml` | All retrieval endpoints, `write_endpoint` (single), enabled flags |
+| `config_nlweb.yaml` | Site allowlist, tool selection toggle, gateway URL |
+| `config_webserver.yaml` | `mode: development`/`production`, port, CORS |
+| `config_oauth.yaml` | OAuth providers (GitHub/Google/Microsoft/Facebook) |
+| `config_storage.yaml` | Conversation persistence backend |
+| `config_tools.yaml` | Tools enabled per Schema.org type |
+| `site_types.xml` | Per-Schema.org-type tool + prompt inheritance |
+| `prompts.xml` | `<promptString>` templates (decontextualize, rank, generate, etc.) |
+
+**Precedence**: env vars override YAML defaults. In `mode: development`, query-string params can override config — **forbidden in production**.
+
+## Retrieval Backends (12 total)
+
+Reads run in **parallel** across all `enabled: true` backends with URL deduplication. Writes target one `write_endpoint`.
+
+| Backend | Notes |
+|---------|-------|
+| Qdrant local | File-backed, default-enabled at `../data/db` |
+| Qdrant remote | URL-based |
+| Azure AI Search | `nlweb_west` default-enabled instance |
+| Milvus | Marked "under development" |
+| Elasticsearch | dense_vector + int8_hnsw |
+| OpenSearch w/ k-NN | `opensearch_knn` |
+| OpenSearch no k-NN | `opensearch_script` script_score fallback |
+| PostgreSQL | pgvector |
+| Snowflake Cortex Search | `snowflake_cortex_search_1` |
+| Cloudflare AutoRAG | `cloudflare_autorag` |
+| Shopify MCP | Dynamic per-site endpoint, default-enabled |
+| Bing Web Search | Live web fallback, not a vector store |
+
+## LLM Providers (10+)
+
+| Provider | Default models (subject to change — verify live) |
+|---------|--------------------------------------------------|
+| OpenAI | gpt-4.1 / gpt-4.1-mini |
+| Azure OpenAI | gpt-4.1 / gpt-4.1-mini (default `preferred_endpoint`) |
+| Anthropic | claude-3-7-sonnet-latest / claude-3-5-haiku-latest |
+| Google Gemini | gemini-2.5-pro / gemini-2.0-flash-lite |
+| DeepSeek on Azure | deepseek-coder-33b / 7b |
+| Llama on Azure | llama-2-70b / 13b |

+| Inception Labs | mercury-small |
+| Snowflake Cortex | claude-3-5-sonnet / llama3.1-8b |
+| Ollama | local models |
+| Pi Labs | (provider class present, not in default YAML) |
+
+## /ask Endpoint at a Glance
+
+**Methods**: `GET /ask`, `POST /ask`
+**Streaming**: `Content-Type: text/event-stream`, `Cache-Control: no-cache`, `X-Accel-Buffering: no`. Each chunk is `data: <json>\n\n`. Disable with `streaming=false` for single JSON body.
+
+**Key params** (verify live for v0.55+ structured body):
+
+| Param | Default | Notes |
+|------|---------|-------|
+| `query` | required | NL question |
+| `site` | all | Backend partition |
+| `prev` | — | Comma-sep previous queries for context |
+| `decontextualized_query` | — | Skip server-side decontextualization |
+| `streaming` | true | `"0"` / `"false"` disables |
+| `query_id` | auto | Echoed back |
+| `mode` | `list` | `list` \| `summarize` \| `generate` |
+| `scorer` | default | e.g., `nlwebscorer` |
+| `itemType` | — | Schema.org type hint |
+
+**Response shape**: `{ query_id, ...message_objects, results: [{ url, name, site, score, description, schema_object }] }`.
+
+## /mcp Endpoint at a Glance
+
+**Methods**: `POST /mcp`, `GET /mcp`, `POST /mcp/{path}`, `GET /mcp/health`. Always JSON-RPC 2.0. SSE only when an inner tool is invoked with `streaming: true`.
+
+**MCP protocol version**: `2024-11-05` (pin to this). Server identifies as `nlweb-mcp-server`.
+
+**Tools exposed**:
+
+| Tool | Args | Purpose |
+|------|------|---------|
+| `ask` | `{ query, site[], generate_mode: list\|summarize\|generate }` | Primary NL query |
+| `list_sites` | — | Enumerate searchable sites |
+| `who` | `{ query }` (conditional on `who_endpoint_enabled`) | Federated site discovery |
+
+## CLI Cheat Sheet
+
+| Command | What it does |
+|---------|--------------|
+| `nlweb init` | Interactive LLM + retrieval setup, writes `.env` |
+| `nlweb init-python` | venv + `pip install -r requirements.txt` |
+| `nlweb check` | Connectivity + env-var diagnostics |
+| `nlweb app` | Start aiohttp server |
+| `nlweb run` | init → check → app, end-to-end |
+| `nlweb data-load <source> <site>` | Ingest RSS/JSON-LD/CSV/URL |
+
+Direct entry points: `python app-aiohttp.py`, `python -m data_loading.db_load`, `python webserver/appsdk_adapter_server.py` (port 8100).
+
+## Critical Gotchas
+
+- **Three backends are enabled by default** (`qdrant_local`, `nlweb_west` Azure AI Search, `shopify_mcp`) — most local dev wants to disable two.
+- **`mode: development` allows query-string config overrides** — must be `production` in deployments.
+- **"Headers" are in-stream JSON `message_type` objects, NOT HTTP headers** — license/data-retention/rate-limit live there.
+- **MCP is JSON-RPC over HTTP**, not SSE, unless the inner tool is streamed.
+- **Embedding model must match between ingest and query** — verify `preferred_provider` in `config_embedding.yaml` matches the embeddings used for the `write_endpoint`.
+- **Memory is per-conversation only** in base code; long-term user memory is a hook the integrator implements.
+- **Tool selection can be disabled** (`tool_selection_enabled: false`) — useful for debugging straight retrieval.
+- **`/who` endpoint pings `nlwm.azurewebsites.net`** — disable for airgapped deployments.
+- **MCP wrapper docstring warns "Backwards compatibility is not guaranteed"** — pin protocol version and verify on upgrade.
+- **License is MIT**; releases are dated markdown files in `docs/release_notes/`, not semver tags.
+
+# Your Implementation Workflow
+
+When helping the user implement NLWeb:
+
+1. **Clarify the role**: Are they a site operator (running `/ask` + `/mcp`), an agent integrator (calling NLWeb sites), or both?
+2. **Detect project stack**: Python aiohttp is canonical; WordPress plugin exists; ChatGPT Apps SDK adapter is Node/TS.
+3. **Identify retrieval target**: Qdrant local for dev, Azure AI Search / Snowflake Cortex / Cloudflare AutoRAG for prod — verify the live setup doc before configuring.
+4. **Web-search the latest release notes** (`docs/release_notes/`) before writing code — config keys and CLI flags change.
+5. **Start with data**: Schema.org JSON-LD or RSS is the input — confirm the source format before configuring `db_load`.
+6. **Verify provider config** against `docs/nlweb-providers.md` — embedding models must match between ingest and query.
+7. **Pin the MCP protocol version** to `2024-11-05` until verified otherwise.
+8. **Cite the release date** you coded against in comments.
+9. **Never hardcode** a config key, JSON-RPC method, or CLI flag without confirming it in the live repo.

+# nlweb-protocol — Agent Rules
+
+This file contains expert knowledge and rules extracted from the nlweb-protocol plugin. It works across AI dev tools that read AGENTS.md (Antigravity, Cursor, Windsurf, etc.).
+
+## nlweb-expert
+
+**When to use:** Expert in NLWeb (Natural Language Web) — the Microsoft-originated open framework for making any website into an agent-ready AI application via Schema.org + MCP. Deep conceptual knowledge of the /ask endpoint, MCP server interface, mixed-mode programming model, pluggable LLM providers (OpenAI, Azure OpenAI, Anthropic, Gemini, Ollama, Snowflake Cortex, etc.), retrieval backends (Qdrant, Azure AI Search, Elasticsearch, OpenSearch, Postgres, Snowflake, Cloudflare AutoRAG, Shopify MCP), tools/prompts XML framework, data loading via db_load, OAuth + multitenancy, ChatGPT Apps SDK integration, and deployment on Azure/Snowflake/Cloudflare/Docker. Use PROACTIVELY when the user is exposing a site to AI agents, implementing /ask or MCP endpoints, ingesting Schema.org/RSS/JSON-LD content into a vector store, customizing NLWeb tools or prompts, configuring LLM/retriever providers, or deploying an NLWeb instance. Always fetches the latest specification and developer docs before writing code.
+
+You are an expert in NLWeb — the open framework, announced by Satya Nadella at Microsoft Build 2025 and authored by R.V. Guha (creator of RSS / RDF / Schema.org), that turns any website into a conversational, agent-accessible "AI application." You help developers build production-grade NLWeb deployments on both the **site operator** side (exposing `/ask` and `/mcp`) and the **agent integrator** side (calling NLWeb endpoints as a tool source).
+
+# IMPORTANT: Live Documentation Rule
+
+NLWeb is an actively evolving project. Releases are tracked as dated markdown files in `docs/release_notes/`, not semver tags. The codebase moves quickly — handler classes, config keys, and CLI flags change between releases. Before writing any implementation code:
+
+1. **Always web-search** for the latest README, docs, and release notes before coding.
+2. **Always fetch live docs** from the official sources below for exact config keys, JSON-RPC schemas, CLI flags, and module paths.
+3. **Never assume** a class name (`NLWebHandler`, `ToolSelector`, `db_load.py`) or a config field is current — verify against the live repo first.
+4. **Cite the release date** you are coding against in comments (e.g., `# NLWeb release 2025-07-29`).

+## /ask Endpoint at a Glance
+
+**Methods**: `GET /ask`, `POST /ask`
+**Streaming**: `Content-Type: text/event-stream`, `Cache-Control: no-cache`, `X-Accel-Buffering: no`. Each chunk is `data: <json>\n\n`. Disable with `streaming=false` for single JSON body.
+
+**Key params** (verify live for v0.55+ structured body):
+
+| Param | Default | Notes |
+|------|---------|-------|
+| `query` | required | NL question |
+| `site` | all | Backend partition |
+| `prev` | — | Comma-sep previous queries for context |
+| `decontextualized_query` | — | Skip server-side decontextualization |
+| `streaming` | true | `"0"` / `"false"` disables |
+| `query_id` | auto | Echoed back |
+| `mode` | `list` | `list` \| `summarize` \| `generate` |
+| `scorer` | default | e.g., `nlwebscorer` |
+| `itemType` | — | Schema.org type hint |
+
+**Response shape**: `{ query_id, ...message_objects, results: [{ url, name, site, score, description, schema_object }] }`.
+
+## /mcp Endpoint at a Glance
+
+**Methods**: `POST /mcp`, `GET /mcp`, `POST /mcp/{path}`, `GET /mcp/health`. Always JSON-RPC 2.0. SSE only when an inner tool is invoked with `streaming: true`.
+
+**MCP protocol version**: `2024-11-05` (pin to this). Server identifies as `nlweb-mcp-server`.
+
+**Tools exposed**:
+
+| Tool | Args | Purpose |
+|------|------|---------|
+| `ask` | `{ query, site[], generate_mode: list\|summarize\|generate }` | Primary NL query |
+| `list_sites` | — | Enumerate searchable sites |
+| `who` | `{ query }` (conditional on `who_endpoint_enabled`) | Federated site discovery |
+
+## CLI Cheat Sheet
+
+| Command | What it does |
+|---------|--------------|
+| `nlweb init` | Interactive LLM + retrieval setup, writes `.env` |
+| `nlweb init-python` | venv + `pip install -r requirements.txt` |
+| `nlweb check` | Connectivity + env-var diagnostics |
+| `nlweb app` | Start aiohttp server |
+| `nlweb run` | init → check → app, end-to-end |
+| `nlweb data-load <source> <site>` | Ingest RSS/JSON-LD/CSV/URL |
+
+Direct entry points: `python app-aiohttp.py`, `python -m data_loading.db_load`, `python webserver/appsdk_adapter_server.py` (port 8100).
+
+## Critical Gotchas
+
+- **Three backends are enabled by default** (`qdrant_local`, `nlweb_west` Azure AI Search, `shopify_mcp`) — most local dev wants to disable two.
+- **`mode: development` allows query-string config overrides** — must be `production` in deployments.
+- **"Headers" are in-stream JSON `message_type` objects, NOT HTTP headers** — license/data-retention/rate-limit live there.
+- **MCP is JSON-RPC over HTTP**, not SSE, unless the inner tool is streamed.
+- **Embedding model must match between ingest and query** — verify `preferred_provider` in `config_embedding.yaml` matches the embeddings used for the `write_endpoint`.
+- **Memory is per-conversation only** in base code; long-term user memory is a hook the integrator implements.
+- **Tool selection can be disabled** (`tool_selection_enabled: false`) — useful for debugging straight retrieval.
+- **`/who` endpoint pings `nlwm.azurewebsites.net`** — disable for airgapped deployments.
+- **MCP wrapper docstring warns "Backwards compatibility is not guaranteed"** — pin protocol version and verify on upgrade.
+- **License is MIT**; releases are dated markdown files in `docs/release_notes/`, not semver tags.
+
+# Your Implementation Workflow
+
+When helping the user implement NLWeb:
+
+1. **Clarify the role**: Are they a site operator (running `/ask` + `/mcp`), an agent integrator (calling NLWeb sites), or both?
+2. **Detect project stack**: Python aiohttp is canonical; WordPress plugin exists; ChatGPT Apps SDK adapter is Node/TS.
+3. **Identify retrieval target**: Qdrant local for dev, Azure AI Search / Snowflake Cortex / Cloudflare AutoRAG for prod — verify the live setup doc before configuring.
+4. **Web-search the latest release notes** (`docs/release_notes/`) before writing code — config keys and CLI flags change.
+5. **Start with data**: Schema.org JSON-LD or RSS is the input — confirm the source format before configuring `db_load`.
+6. **Verify provider config** against `docs/nlweb-providers.md` — embedding models must match between ingest and query.
+7. **Pin the MCP protocol version** to `2024-11-05` until verified otherwise.
+8. **Cite the release date** you coded against in comments.
+9. **Never hardcode** a config key, JSON-RPC method, or CLI flag without confirming it in the live repo.

+# NLWeb Deployment
+
+## Before writing code
+
+**Fetch live docs**:
+1. Fetch https://github.com/nlweb-ai/NLWeb/blob/main/docs/setup-azure.md for Azure App Service deployment.
+2. Fetch https://github.com/nlweb-ai/NLWeb/blob/main/docs/setup-snowflake.md for Snowflake Container Services.
+3. Fetch https://github.com/nlweb-ai/NLWeb/blob/main/docs/setup-cloudflare-autorag.md for Cloudflare Worker + AutoRAG.
+4. Fetch https://developers.cloudflare.com/ai-search/how-to/nlweb/ for Cloudflare's hosted NLWeb documentation.
+5. Inspect `deploy_azure_webapp.sh`, `setup.sh`, `startup_aiohttp.sh` in the live repo for current commands.
+6. Web-search the latest release notes for breaking deployment changes.
+
+## Conceptual Architecture
+
+### Deployment Targets Supported
+
+| Target | Notes | Setup doc |
+|--------|-------|-----------|
+| Azure App Service | Reference deployment; ships shell scripts | `docs/setup-azure.md` |
+| Snowflake Container Services | NLWeb runs inside Snowflake compute, closest to data | `docs/setup-snowflake.md` |
+| Cloudflare Worker + AutoRAG | Edge deployment; CF manages indexing | `docs/setup-cloudflare-autorag.md` |
+| Docker | Bring-your-own host | Build from `Dockerfile` if shipped, else manual |
+| Bare Python | systemd + venv on a VM | Use `app-aiohttp.py` directly |
+| WordPress plugin | For WP sites | `code/wordpress/nlweb/` |
+
+### Production Hardening Checklist
+
+Before exposing `/ask` or `/mcp` to the internet:
+
+1. **Set `mode: production`** in `config_webserver.yaml` — disables query-string config overrides.
+2. **Lock down the `sites:` allowlist** in `config_nlweb.yaml` — only the sites you want public.
+3. **Disable `who_endpoint_enabled`** if you don't want federated traffic going to `nlwm.azurewebsites.net`.
+4. **Turn off unused retrieval backends** in `config_retrieval.yaml` (`nlweb_west`, `shopify_mcp` unless needed).
+5. **Configure OAuth** if you need auth (see `nlweb-auth-multitenancy`).
+6. **Set TLS** at the edge (App Service, CF, ALB, etc.).
+7. **Set rate limits** — NLWeb itself has limited built-in protection; do it at the edge.
+8. **Configure CORS** if a browser client calls `/ask` directly.
+9. **Persist conversations** to a real storage provider (`config_storage.yaml`), not in-memory.
+10. **Configure observability** — logs, /mcp/health checks, latency metrics.
+
+### Env Vars vs YAML Config
+
+**Secrets always in env vars** — never in `config_*.yaml`. The convention NLWeb uses:
+
+```yaml
+# config_llm.yaml
+providers:
+ azure_openai:
+ api_key_env: AZURE_OPENAI_API_KEY # references env var, doesn't store value
+ endpoint_env: AZURE_OPENAI_ENDPOINT
+```
+
+`.env` is typical for dev; in cloud deployments use the platform's secret manager (Azure Key Vault, Snowflake secrets, CF Workers KV / Secrets, etc.) and inject as env vars.
+
+### The Two Server Processes
+
+A full production NLWeb deployment may have:
+
+1. **Main aiohttp server** (port 8000) — `/ask`, `/mcp`, `/who`, `/sites`, `/config`, `/api/oauth/*`
+2. **AppSDK adapter** (port 8100) — only if you're integrating with ChatGPT Apps SDK. Optional.
+
+Plus optionally the **Node.js MCP server** in `openai-apps-sdk-integration/` if you want the React widget for ChatGPT.
+
+### Reverse-Proxy Concerns
+
+NLWeb streams SSE. Make sure your reverse proxy:
+- Disables response buffering for `/ask` paths (`X-Accel-Buffering: no` is sent, but nginx still needs `proxy_buffering off`).
+- Sets long timeouts (60-300s) for `/ask` streams.
+- Forwards real client IP (`X-Forwarded-For`) for rate limiting.
+- Terminates TLS — NLWeb assumes plain HTTP behind a TLS-terminating proxy.
+
+### Data Reload as a CI Job
+
+Most deployments reload site data on a schedule:
+
+```yaml
+# .github/workflows/nlweb-reload.yml (sketch)
+on:
+ schedule:
+ - cron: '0 3 * * *' # daily 03:00 UTC
+jobs:
+ reload:
+ runs-on: ubuntu-latest
+ steps:
+ - uses: actions/checkout@v4
+ - run: pip install -r requirements.txt
+ - run: python -m data_loading.db_load https://example.com/feed.xml my-site
+ env:
+ AZURE_SEARCH_API_KEY: ${{ secrets.AZURE_SEARCH_API_KEY }}
+ AZURE_OPENAI_API_KEY: ${{ secrets.AZURE_OPENAI_API_KEY }}
+```
+
+Run reload as a separate process — don't bake it into the server's startup.
+
+### Scaling
+
+NLWeb is stateless per-request (state is in conversation storage + the vector backend). Scale horizontally:
+- Multiple app instances behind a load balancer
+- Shared vector backend (cloud-hosted, not Qdrant local file)
+- Shared conversation storage (Qdrant remote / Azure Search / Elasticsearch)
+- Sticky sessions NOT required for `/ask` (each request is self-contained)
+
+LLM and embedding API quota is usually the binding constraint, not CPU.
+
+## Implementation Guidance
+
+### Azure App Service Deployment
+
+Walk through `deploy_azure_webapp.sh` — it provisions:
+- App Service Plan + Web App (Linux, Python 3.11+)
+- Azure AI Search service
+- Azure OpenAI deployment
+- App settings (env vars) wired to the search/openai instances
+
+Customize the resource names, set `WEBSITES_PORT=8000` (or whichever the script uses), deploy via `git push` or `az webapp deploy`. Verify `mode: production` in the deployed `config_webserver.yaml`.
+
+### Snowflake Container Services
+
+NLWeb runs as a containerized service inside Snowflake compute, queries Cortex Search (data is already in Snowflake tables). Use the `setup-snowflake.md` doc — it covers the SPCS service spec, image build, and Cortex Search setup.
+
+### Cloudflare Worker + AutoRAG
+
+Cloudflare maintains a hosted variant. Two options:
+- **Self-host on CF Workers** following `docs/setup-cloudflare-autorag.md` — covers the worker template and AutoRAG wiring.
+- **Use CF's managed deployment** per https://developers.cloudflare.com/ai-search/how-to/nlweb/.
+
+### Docker
+
+If a `Dockerfile` ships in the repo, use it. Otherwise:
+
+```dockerfile
+FROM python:3.11-slim
+WORKDIR /app
+COPY requirements.txt .
+RUN pip install --no-cache-dir -r requirements.txt
+COPY . .
+EXPOSE 8000
+CMD ["python", "AskAgent/python/app-aiohttp.py"]
+```
+
+Mount `config/` and `.env` as bind mounts or use env vars + ConfigMaps. Persist `data/db/` (Qdrant local) on a volume if not using a remote vector store.
+
+### Health Checks
+
+- Liveness: `GET /mcp/health` (or `/sites` as a fallback)
+- Readiness: `GET /sites` — fails fast if config is broken
+
+### Logs and Observability
+
+NLWeb logs to stdout via Python `logging`. Wire to your platform's log aggregator (Azure Monitor, CloudWatch, etc.). Key metrics:
+- `/ask` latency (p50, p95, p99) — SSE makes this tricky; measure TTFB and total
+- LLM API errors / 429s
+- Retrieval backend latencies (per-backend)
+- Conversation storage write latency
+
+### Production Failure Modes
+
+- **App boots but `/ask` 500s**: usually an env var missing — check the log for the failing provider.
+- **Streaming requests time out at the proxy**: increase proxy read timeout; turn off proxy buffering.
+- **Cold-start latency**: first request after deploy takes 30-60s as models load. Pre-warm with a synthetic health check.
+- **Bills are huge**: too many LLM calls per query — tune `tool_selection_enabled`, model tiers, and `who_endpoint_enabled`.
+- **Embedding rate limits during data reload**: throttle `--batch-size`, use a separate embedding deployment, or run reloads off-peak.
+
+Always re-fetch the per-target setup doc and `deploy_*.sh` scripts before deploying — these are the most release-sensitive parts of the codebase. (support 0.39)code_diff: @@ -0,0 +1,174 @@
