**Date**: 2026-02-05
**Task**: Task 3 - Implement GossipConfig
**Reviewer**: Automated Build Validation
**Iteration**: 1

## Summary

Task 3 successfully implemented complete GossipConfig with all parameters from ROADMAP Phase 1.3 requirements. All defaults match specified values.

## Changes Reviewed

### src/gossip/config.rs (modified)
- ✅ Added 10 configuration fields with proper types and documentation
- ✅ HyParView parameters: active_view_size (10), passive_view_size (96)
- ✅ SWIM parameters: probe_interval (1s), suspect_timeout (3s)
- ✅ Presence parameters: presence_beacon_ttl (15min)
- ✅ Anti-entropy: anti_entropy_interval (30s)
- ✅ FOAF parameters: foaf_ttl (3), foaf_fanout (3)
- ✅ Message cache: message_cache_size (10k), message_cache_ttl (5min)
- ✅ Custom serde Duration serialization (seconds as u64)
- ✅ Comprehensive tests for defaults and serialization

### Cargo.toml (modified)
- ✅ Added serde_json to dev-dependencies for config tests

## Build Validation

| Check | Result | Details |
|-------|--------|---------|
| `cargo check --all-features --all-targets` | ✅ PASS | 0 errors |
| `cargo clippy --all-features --all-targets -- -D warnings` | ✅ PASS | 0 warnings |
| `cargo nextest run --all-features` | ✅ PASS | 64/64 tests (+2 new) |
| `cargo fmt --all -- --check` | ✅ PASS | All files formatted |

## Test Coverage

New tests:
1. `test_default_config` - Verifies all default values match ROADMAP
2. `test_config_serialization` - Validates serde round-trip

Both tests pass.

## Findings

### CRITICAL: None

### IMPORTANT: None

### MINOR: None

## ROADMAP Compliance

All Phase 1.3 configuration parameters implemented:
- ✅ HyParView: 8-12 active, 64-128 passive (defaults 10, 96)
- ✅ SWIM: 1s probes, 3s suspect timeout
- ✅ Presence: 15min TTL
- ✅ Anti-Entropy: 30s interval
- ✅ FOAF: TTL=3, fanout=3
- ✅ Message cache: 10k size, 5min TTL

## Verdict

**PASS** ✅

Task 3 complete. GossipConfig fully implemented and tested.

## Next Steps

Proceed to Task 4: Create Transport Adapter wrapping ant-quic NetworkNode.
