Attestation Fuzz Harness

Implements bounty #762.

Milestones

Milestone Status Expected RTC
Fuzz harness — generates random valid/invalid attestation payloads ✅ 50 RTC
10,000+ test corpus — saved regression fixtures via --save-corpus ✅ +15 RTC
CI integration — --ci exits non-zero on crash found ✅ +10 RTC

Total expected: 75 RTC (crash reports would add +25 RTC per unique crash)

File: testing/attest_fuzz.py

11 Mutation Strategies:

Strategy Description
missing_field Remove required fields at any nesting level
wrong_type Replace field with wrong type (None, int, list, dict, float, inf, nan)
unknown_field Inject unknown keys at any nesting level
nested_bomb Deeply nested structures (100-500 levels)
array_overflow Huge MAC arrays (1000-10000 entries)
float_edge inf, -inf, nan, 1e308 in fingerprint data
unicode_miner null bytes, RTL override, emoji, path traversal, SQL injection
huge_miner Wallet names up to 1MB
null_miner Explicit null value
empty_payload {}
not_json Random binary garbage with wrong Content-Type

Crash Detection:

  • HTTP 5xx = server error
  • Timeout > 90% of limit = potential DoS
  • Traceback/exception in response body
  • Connection refused = server crash

Usage

# Basic run (1000 iterations)
python3 testing/attest_fuzz.py

# Full corpus run
python3 testing/attest_fuzz.py --count 10000 --save-corpus

# CI mode
python3 testing/attest_fuzz.py --count 1000 --ci

# Custom target
python3 testing/attest_fuzz.py --url http://localhost:8099

# Show crash report
python3 testing/attest_fuzz.py --report

feat(rip-0002): On-Chain Governance System — proposal creation, votin…

…g, lifecycle, Sophia AI analysis

Implements RIP-0002 governance spec with:
- POST /api/governance/propose  — Create proposal (active miner required)
- GET  /api/governance/proposals — List proposals with status filter
- GET  /api/governance/proposal/<n> — Proposal details + vote history
- POST /api/governance/vote      — Cast/change vote (antiquity-weighted)
- GET  /api/governance/results/<n> — Final results + quorum status
- POST /api/governance/veto/<n>  — Founder veto (2-year window, env-key)
- GET  /api/governance/stats     — Governance statistics

Features:
- 3 proposal types: parameter_change, feature_activation, emergency
- 3 vote choices: for, against, abstain (vote changes allowed)
- 7-day voting window with automatic settlement
- 33% quorum threshold of active miners
- Antiquity-weighted votes (from miners table)
- Sophia AI lightweight risk analysis (HIGH/LOW)
- Founder veto for security-critical proposals (first 2 years)
- Anti-spam: max 10 active proposals per miner
- 19 passing tests covering all scenarios

feat: pip install rustchainnode — installable RustChain attestation node
197050f 
Implements bounty Scottcjn#757: package the RustChain node as a pip-installable PyPI package.

pip install rustchainnode
rustchainnode init --wallet my-wallet-name
rustchainnode start

Features:
- CLI commands: init, start, stop, status, config, dashboard, install-service
- Auto-configuration: detects CPU arch, thread count, antiquity multiplier
- Cross-platform: Linux x86_64/aarch64/ppc64, macOS x86/ARM64
- Systemd (Linux) + launchd (macOS) service generation
- TUI dashboard: rustchainnode dashboard
- Programmatic API: from rustchainnode import RustChainNode
- Zero external dependencies (stdlib only)
- Python 3.9+ compatible

feat: cross-node ledger verification tool (Scottcjn#763)
a4f1f55 
Queries all 3 RustChain nodes, compares state, alerts on mismatches.

Features:
- Query /health, /epoch, /api/stats, /wallet/balance, /api/miners
- Merkle root computation over sorted active miners list
- SQLite historical tracking (~/.rustchain/ledger_verify.db)
- Webhook alerting on mismatch (--webhook URL)
- CI mode: --ci exits non-zero on any mismatch
- Watch mode: --watch N runs every N seconds
- History viewer: --history shows recent checks

Sample output:
  Node 1 (Primary): v2.2.1-rip200 ✅ epoch=94 slot=13601
  Node 2: v1.2.0 ✅ epoch=94 slot=13601
  Node 3 (Ryan): ❌ unreachable (Tailscale)
  Merkle roots: node1=e318be4c... (both match ✅)
  Result: ✅ ALL NODES IN SYNC

GitHub Actions: runs every 6h, CI mode, webhook on mismatch.
