Backend:
- Add Trust Ledger (reputation.ts): getReputation() + getReputationEvents()
with two-tier RPC fallback for on-chain reputation reads
- Add settlements.ts: persist x402 settlements to data/settlements.json
- Add MCP Server (src/mcp/server.ts): 5 tools (list_agents, suggest_agents,
dispatch_task, get_task_status, read_payment_history) via stdio transport
- Fix /agents/:hash/reputation route to return { reputation, events }
- Enrich /agents with tasksFailed/lastUpdated from chain
- Add GET /x402/history route for settlement records
- Replace require() with lazy import() in casperHandler.ts
Frontend:
- Add agent trust page (agents/[hash]/page.tsx): score bar, completion/failure
counts, explorer-linked reputation events table
- Add use-agent-reputation hook
- Add pay-agent.tsx component: x402 signTypedData payment flow
- Update payments page to fetch real settlement data from /x402/history
- Fix rating derivation: reputationScore / 2000 (not old formula)
- Add demo badge to AgentCard with FlaskConical icon
- Link agent names to trust pages
- Fix React hooks: eliminate synchronous setState in effects
CI/Lint:
- Create eslint.config.mjs for frontend (next lint removed in Next.js 16)
- Fix backend lint: 0 errors (was 2 require()-import errors)
- Fix frontend lint: 0 errors, 0 warnings
- All checks green: backend 8/8 tests, frontend 6/6 tests,
contracts 29/29 tests, tsc clean, next build clean
