# DSLLVM Telemetry Enforcement Guide
2+
3+
**Version:** 1.3.0
4+
**Feature:** Minimum Telemetry Enforcement (Phase 1, Feature 1.3)
5+
**SPDX-License-Identifier:** Apache-2.0 WITH LLVM-exception
6+
7+
## Overview
8+
9+
Telemetry enforcement prevents "dark functions" - critical code paths with zero forensic trail. DSLLVM enforces compile-time telemetry requirements for safety-critical and mission-critical functions, ensuring observability for:
10+
11+
- **Layer 5 Performance AI**: Optimization feedback
12+
- **Layer 62 Forensics**: Post-incident analysis
13+
- **Mission compliance**: Telemetry level enforcement
14+
15+
## Enforcement Levels
16+
17+
### Safety-Critical (`DSMIL_SAFETY_CRITICAL`)
18+
19+
**Requirement**: At least ONE telemetry call
20+
**Use Case**: Important functions requiring basic observability
21+
22+
```c
23+
DSMIL_SAFETY_CRITICAL("crypto")
24+
DSMIL_LAYER(3)
25+
void ml_kem_encapsulate(const uint8_t *pk, uint8_t *ct) {
26+
dsmil_counter_inc("ml_kem_calls"); // ✓ Satisfies requirement
27+
// ... crypto operations ...
28+
}
29+
```
30+
31+
### Mission-Critical (`DSMIL_MISSION_CRITICAL`)
32+
33+
**Requirement**: BOTH counter AND event telemetry + error path coverage
34+
**Use Case**: Critical functions requiring comprehensive observability
35+
36+
```c
37+
DSMIL_MISSION_CRITICAL
38+
DSMIL_LAYER(8)
39+
int detect_threat(const uint8_t *pkt, size_t len, float *score) {
40+
dsmil_counter_inc("threat_detection_calls"); // Counter required
41+
dsmil_event_log("threat_detection_start"); // Event required
42+
43+
int result = analyze(pkt, len, score);
44+
45+
if (result < 0) {
46+
dsmil_event_log("threat_detection_error"); // Error path logged
47+
return result;
48+
}
49+
50+
dsmil_event_log("threat_detection_complete");
51+
return 0;
52+
}
53+
```
54+
55+
## Telemetry API
56+
57+
### Counter Telemetry
58+
59+
```c
60+
// Increment counter (atomic, thread-safe)
61+
void dsmil_counter_inc(const char *counter_name);
62+
63+
// Add value to counter
64+
void dsmil_counter_add(const char *counter_name, uint64_t value);
65+
```
66+
67+
**Use for**: Call frequency, item counts, resource usage
68+
69+
### Event Telemetry
70+
71+
```c
72+
// Simple event (INFO severity)
73+
void dsmil_event_log(const char *event_name);
74+
75+
// Event with severity
76+
void dsmil_event_log_severity(const char *event_name,
77+
dsmil_event_severity_t severity);
78+
79+
// Event with message
80+
void dsmil_event_log_msg(const char *event_name,
81+
dsmil_event_severity_t severity,
82+
const char *message);
83+
```
84+
85+
**Use for**: State transitions, errors, security events
86+
87+
### Performance Metrics
88+
89+
```c
90+
void *timer = dsmil_perf_start("operation_name");
91+
// ... operation ...
92+
dsmil_perf_end(timer);
93+
```
94+
95+
**Use for**: Latency measurement, performance optimization
96+
97+
## Compilation
98+
99+
```bash
100+
# Enforce telemetry requirements (default)
101+
dsmil-clang -fdsmil-telemetry-check src.c -o app
102+
103+
# Warn only
104+
dsmil-clang -mllvm -dsmil-telemetry-check-mode=warn src.c
105+
106+
# Disable
107+
dsmil-clang -mllvm -dsmil-telemetry-check-mode=disabled src.c
108+
```
109+
110+
## Mission Profile Integration
111+
112+
Mission profiles enforce telemetry levels:
113+
114+
- `border_ops`: minimal (counter-only acceptable)
115+
- `cyber_defence`: full (comprehensive required)
116+
- `exercise_only`: verbose (all telemetry enabled)
117+
118+
```bash
119+
dsmil-clang -fdsmil-mission-profile=cyber_defence \
120+
-fdsmil-telemetry-check src.c
121+
```
122+
123+
## Common Violations
124+
125+
### Missing Telemetry
126+
127+
```c
128+
// ✗ VIOLATION
129+
DSMIL_SAFETY_CRITICAL
130+
void critical_op() {
131+
// No telemetry calls!
132+
}
133+
```
134+
135+
**Error:**
136+
```
137+
ERROR: Function 'critical_op' is marked dsmil_safety_critical
138+
but has no telemetry calls
139+
```
140+
141+
### Missing Counter (Mission-Critical)
142+
143+
```c
144+
// ✗ VIOLATION
145+
DSMIL_MISSION_CRITICAL
146+
int mission_op() {
147+
dsmil_event_log("start"); // Event only, no counter!
148+
return do_work();
149+
}
150+
```
151+
152+
**Error:**
153+
```
154+
ERROR: Function 'mission_op' is marked dsmil_mission_critical
155+
but has no counter telemetry (dsmil_counter_inc/add required)
156+
```
157+
158+
## Best Practices
159+
160+
1. **Add telemetry early**: At function entry
161+
2. **Log errors**: All error paths need telemetry
162+
3. **Use descriptive names**: `"ml_kem_calls"` not `"calls"`
163+
4. **Component prefix**: `"crypto.ml_kem_calls"` for routing
164+
5. **Avoid PII**: Don't log sensitive data
