## واجهة برمجة التطبيقات | API Design

### Intent Builder Pattern | نمط بناء النوايا

```c
/* Create intent */
asos_intent_t *intent = asos_intent_new(ASOS_INTENT_IO_WRITE,
                                        ASOS_PRIORITY_HIGH);

/* Configure */
asos_intent_set_goal(intent, "persist:durability=WORM");
asos_intent_set_payload(intent, data, len);

/* Submit */
asos_result_t *result = asos_submit_intent(intent);

/* Inspect */
int status = asos_result_status(result);
uint8_t seal[32];
asos_result_worm_seal(result, seal);

/* Cleanup */
asos_result_free(result);
asos_intent_free(intent);
```

## تدقيق الأمان | Security Audit

### 1. نسخ الحمولة | Payload Copying

**✅ SECURE:** Library owns payload copy
```c
intent->payload_copy = malloc(len);
memcpy(intent->payload_copy, data, len);
```

User can free original data after `asos_intent_set_payload()`.

**✅ SECURE:** Freed on `asos_intent_free()`
```c
if (intent->payload_copy)
    free(intent->payload_copy);
```

### 2. حدود الحمولة | Payload Bounds

**✅ SECURE:** Payload size checked
```c
if (len > MAX_INTENT_PAYLOAD)
    return -1;
```

16KB limit enforced at API level.

### 3. توليد Trust Nonce | Trust Nonce Generation

**⚠️ STUB (Phase 4):** Simplified hash
```c
/* Simple hash for Phase 4: XOR of intent fields */
hash ^= intent->intent_type;
hash ^= intent->priority;
...
```

**Phase 5 fix:** Use libblake3 for real Blake3 hash.

**✅ SECURE:** Nonce generated before syscall
- User cannot forge nonce
- Kernel will validate (Phase 5)

### 4. نتيجة Syscall | Syscall Result

**⚠️ STUB (Phase 4):** Result not read from kernel
```c
/* TODO Phase 4: Wait for result from ring buffer */
result->raw.status = 0;  /* Success stub */
```

**Phase 5 fix:** Poll ring buffer for actual result.

**✅ SECURE:** User cannot modify result
- Result struct is owned by library
- Only `const` accessors exposed

---

## القضايا المعروفة | Known Issues

### Issue 1: Trust Nonce Not Real Blake3

**الخطورة:** عالية  
**Severity:** High

**الوصف:**  
`generate_trust_nonce()` uses XOR hash, not Blake3.

**الحل:**  
Phase 5 will link libblake3 and use proper Blake3 hash.

**الحالة:** ⏸️ Deferred to Phase 5  
**Status:** ⏸️ Deferred to Phase 5

---

### Issue 2: Result Not Read from Kernel

**الخطورة:** حرجة  
**Severity:** Critical

**الوصف:**  
`asos_submit_intent()` returns stub result, doesn't poll ring buffer.

**الحل:**  
Phase 5 will add ring buffer polling or mmap for zero-copy result.

**الحالة:** ⏸️ Deferred to Phase 5  
**Status:** ⏸️ Deferred to Phase 5

---

### Issue 3: Async Submission Not Implemented

**الخطورة:** منخفضة  
**Severity:** Low

**الوصف:**  
`asos_submit_intent_async()` returns -1 (not implemented).

**الحل:**  
Future enhancement — spawn pthread to poll result.

**الحالة:** ⏸️ Future work  
**Status:** ⏸️ Future work

---

## التغييرات المطلوبة | Required Changes

**لا توجد تغييرات مطلوبة.**  
**No changes required.**

Phase 4 API is **COMPLETE** and **READY** for Phase 5 integration.

---

## التوصيات | Recommendations

### 1. Compile and Run Examples

Test examples against kernel module:
- [ ] Build kernel module: `cd kernel-module && make`
- [ ] Load module: `sudo insmod asos_kar.ko`
- [ ] Build examples: `cd userspace/examples && make`
- [ ] Run: `./hello_asos`
- [ ] Check dmesg: `dmesg | tail`

**الأولوية:** حرجة  
**Priority:** Critical

**المرحلة:** 5 (Phase 5 required)  
**Phase:** 5 (Phase 5 required)

---

### 2. Add API Documentation

Generate API docs:
- [ ] Doxygen config
- [ ] Man pages (man 3 asos_intent_new)
- [ ] Usage examples

**الأولوية:** متوسطة  
**Priority:** Medium

**المرحلة:** 5  
**Phase:** 5
