+
+## Snapshots
+
+Snapshots capture a complete point-in-time record of coverage metrics. They enable

+
+### Creating a Snapshot
+
+**Manual** (leads, admin):
+```http
+POST /api/v1/snapshots
+{"notes": "Pre-campaign baseline — March 2024"}

+**Automatic**: The system creates snapshots automatically:
+- After every campaign completion
+- After MITRE sync
+- On a scheduled basis (configurable)

+
+```http
+GET /api/v1/snapshots?limit=10&offset=0
+```
+
+### Coverage Evolution (Trend)
+
+```http
+GET /api/v1/snapshots/evolution?limit=50
+```
+
+Returns time-ordered list of snapshots with key metrics — ideal for plotting a
+trend line of coverage improvement over time.
+
+### Comparing Two Snapshots
+
+```http
+GET /api/v1/snapshots/compare?a=<snapshot_id_1>&b=<snapshot_id_2>
+```
+
+Returns a diff showing:
+- Techniques newly covered since snapshot A
+- Techniques that lost coverage
+- Score delta
+- Test count delta
+
+### Deleting a Snapshot
+
+Only admins can delete snapshots:
+```http
+DELETE /api/v1/snapshots/{id}
+```
