# P6.10 Wire §14.8 resource-aware config defaults - Verification Summary

## Task: bf-4w08

Verified that all §14.8 resource-aware configuration defaults are properly wired into Rust code and Helm chart.

## Acceptance Criteria Status

### 1. Each §14.8 key present in `crates/miroir-core/src/config/` with documented default
- ✅ `server`: max_body_bytes: 104857600, max_concurrent_requests: 500, request_timeout_ms: 30000
- ✅ `connection_pool_per_node`: max_idle: 32, max_total: 128, idle_timeout_s: 60
- ✅ `task_registry`: cache_size: 10000, redis_pool_max: 50
- ✅ `idempotency`: max_cached_keys: 1000000, ttl_seconds: 86400
- ✅ `session_pinning`: max_sessions: 100000
- ✅ `query_coalescing`: max_subscribers: 1000, max_pending_queries: 10000
- ✅ `anti_entropy`: max_read_concurrency: 2, fingerprint_batch_size: 1000
- ✅ `resharding`: backfill_concurrency: 4, backfill_batch_size: 1000
- ✅ `peer_discovery`: service_name: "miroir-headless", refresh_interval_s: 15
- ✅ `leader_election`: enabled: true, lease_ttl_s: 10, renew_interval_s: 3

### 2. `charts/miroir/values.yaml` exposes same keys with identical defaults
- ✅ All §14.8 defaults present in values.yaml (lines 69-120)
- ✅ Values match plan §14.8 exactly

### 3. `values.schema.json` accepts documented ranges; rejects nonsense
- ✅ Schema defines all §14.8 properties with appropriate types
- ✅ Cross-field validation for `lease_ttl_s > renew_interval_s` in `_helpers.tpl`
- ✅ JSON Schema rules 0-6 enforce HA requirements (replicas > 1 requires redis, etc.)

### 4. K8s resources block matches §14.8 (500m/2000m CPU, 1Gi/3584Mi mem)
- ✅ `values.yaml` resources block (lines 47-53):
  - requests: cpu: 500m, memory: 1Gi
  - limits: cpu: 2000m, memory: 3584Mi
- ✅ Deployment template uses these via `{{ .Values.miroir.resources }}`

### 5. Unit test: drift guard comparing Config::default() to §14.8 reference
- ✅ Test `section_14_8_defaults_match` in `crates/miroir-core/src/config.rs` (lines 685-728)
- ✅ Test passes: all defaults verified against §14.8 values

### 6. Drift guard: doc-test comparing Config::default() to §14.8 reference
- ✅ Doc-test at top of `MiroirConfig` struct (lines 21-45 in config.rs)
- ✅ Doc-test passes with `cargo test --doc`

## Test Results

```bash
$ cargo test section_14_8_defaults_match --lib
test config::tests::section_14_8_defaults_match ... ok

test result: ok. 1 passed; 0 failed
```

## Files Verified

- `crates/miroir-core/src/config.rs` - Core config struct with defaults
- `crates/miroir-core/src/config/advanced.rs` - Advanced feature configs
- `charts/miroir/values.yaml` - Helm chart values with §14.8 defaults
- `charts/miroir/values.schema.json` - JSON Schema validation
- `charts/miroir/templates/_helpers.tpl` - Cross-field validation
- `charts/miroir/templates/miroir-deployment.yaml` - Resources block

## Conclusion

All §14.8 resource-aware configuration defaults are properly wired and validated. The drift guard test and doc-test ensure defaults cannot drift from the plan without failing CI.
