Restore test fixture runtime prerequisites and align assertions with current Evidence and uncertainty contracts. Separate actual CLI publisher refusal from explicitly admitted Hopper socket/CLI fixtures, retaining exact wire identity and cleanup coverage. Validate retained EVM Evidence against exact unchanged source-carrier bytes.
Validation: 88 targeted local test passes across three completed selections, two platform skips, full check:ci; hosted Windows probes and complete current-head CI. No production authority, authentication or schema change. Controlled fixtures do not qualify actual disassemblers or workers.
Fixes#4690.
Keep malformed JEB-only timeouts isolated from shared CLI/MCP startup while strict registration and JEB configuration checks remain authoritative. Cover built CLI discovery and the production stdio MCP refusal and peer requests.
