Governance, account, block and pool had only live integration suites. Two consequences:

• The mainnet suites are excluded from the coverage job, so GovernanceServiceImpl reported 5.5% despite being exercised nightly. The number was measuring the test selection, not the code.
• A live suite cannot assert what request was sent — only that something came back. Endpoint wiring, body construction and filter handling were all untested.

Change

MockWebServer suites for all four services, following the pattern from #205.

They assert that each method reaches the endpoint it should, that bulk calls POST their ids in the body, that epoch filters actually reach the query string or body, that a null Options does not NPE, and that invalid input is rejected before any request leaves the client — verified with server.getRequestCount() == 0 rather than assumed.

Coverage

	Before	After
GovernanceServiceImpl	5.5%	98.2%
Overall lines	81.8%	92.3%
Overall instructions	81.4%	93.1%
Overall branches	71.2%	78.8%
Overall methods	84.4%	95.6%

17 tests, all offline, about 8 seconds added to the suite. Nothing here can flake on a live Koios instance or contribute to rate limiting.

What is deliberately left

BaseService keeps 26 uncovered lines, nearly all of them the seven System.getenv branches in its constructor. getenv is immutable in-process, so covering them means subprocesses per permutation or a seam added to production code purely for tests. The remaining service impls are single-digit gaps not worth the noise.
