test: cover economy stats and wallet mutation resolvers

[mojobeeping]

Summary

Adds focused Vitest coverage for two GraphQL resolver areas:

• tests/graphql/economy-stats.test.ts
  • maps aggregate DB rows into the public economy stats shape
  • covers zero/default fallback behavior when aggregate rows are missing
• tests/graphql/wallet-mutations.test.ts
  • covers authenticated addWallet insertion payloads and default isPrimary behavior
  • covers unauthenticated addWallet rejection
  • covers syncWalletBalance updating the sync timestamp and returning the updated row

Both files use mocked DB chains, so they do not require Postgres or external services.

Relates to #8.

Validation

Passed:

npm test -- --run tests/graphql/economy-stats.test.ts tests/graphql/wallet-mutations.test.ts
npm test -- --run
git diff --check

Result: 2 test files passed, 5 tests passed.

Previously attempted:

npm run build

The build currently fails on existing project-level TypeScript/config issues unrelated to these test files, including database/schema/agents.ts self-reference typing, rootDir mismatch for database/**/*, src/graphql/resolvers.ts query result typing, and missing @as-integrations/fastify. The new test files are not referenced in those build errors.

Bounty Note

Issue #8 lists an ongoing bounty of 50 sats per merged test file. This PR now adds two test files. Payout details can be provided if this PR is accepted.

Code Review

This pull request introduces a new test suite for the economyStats GraphQL resolver, verifying that it correctly maps aggregate database query results into the public economy stats shape and handles missing aggregate rows by returning zeroed stats. The reviewer provided feedback to improve TypeScript idiomatic usage by replacing as never type assertions with as any for partial mocks, and suggested using toEqual instead of toMatchObject for stricter assertions.

Using as never as a type assertion escape hatch is non-idiomatic in TypeScript. The never type represents values that should never occur. For partial mocks in tests, as any is the standard and idiomatic way to bypass type checking.

Suggested change

	const resolvers = createResolvers(db as never);
	const resolvers = createResolvers(db as any);

[gemini-code-assist]

For consistency and stricter assertions, use toEqual instead of toMatchObject. This ensures that the resolver does not return any unexpected extra properties beyond the defined schema.

Suggested change

	await expect(resolvers.Query.economyStats()).resolves.toMatchObject({
	totalAgents: 12,
	sovereignAgents: 3,
	activeAgents: 9,
	tasksCompletedToday: 4,
	tasksCompletedTotal: 27,
	totalCirculating: '0',
	dailyVolume: '0',
	averageEmergenceScore: 0,
	emergenceEventsToday: 0,
	});
	await expect(resolvers.Query.economyStats()).resolves.toEqual({

Addressed the automated review feedback in f91b0fb: switched the economyStats populated-case assertion to toEqual and replaced the local test mock as never casts with as any. Re-ran npm test -- --run tests/graphql/economy-stats.test.ts tests/graphql/wallet-mutations.test.ts, npm test -- --run, and git diff --check; all pass.
