## Description
|
|
Manages runtime trace lifecycle with configurable retention periods (default 30 days), automatic pruning of old traces while preserving those referenced by active slices, trace aggregation, and storage quota enforcement.
|
|
|
|
## Implementation Details
|
|
- **Trace Retention Manager**:
|
|
- `src/Scanner/__Libraries/StellaOps.Scanner.Runtime/Retention/TraceRetentionManager.cs` - `TraceRetentionManager` managing runtime trace lifecycle with configurable retention periods (default 30 days), automatic pruning of expired traces while preserving those referenced by active reachability slices, trace aggregation, and storage quota enforcement
|
|
|
|
## E2E Test Plan
|
|
- [ ] Configure a 30-day retention period and verify traces older than 30 days are automatically pruned
|
|
- [ ] Verify traces referenced by active reachability slices are preserved even if they exceed the retention period
|
|
- [ ] Verify trace aggregation combines repeated observations into summary records before pruning individual traces
|
|
- [ ] Configure a storage quota and verify the retention manager prunes oldest traces when quota is exceeded
|
|
- [ ] Verify pruning is idempotent (running multiple times produces the same result)
|
|
- [ ] Verify retention configuration can be updated without data loss
