Validated on the combined 8-PR board: all seven CLI command suites green (combo-suggest, compression, mcp-call, oneproxy, resilience, skills + the shared mcpStreamMock helper) within the board's 88/88, typecheck:core clean, gates within baseline. The CLI mcp call protocol fixes (BUG-001) land with full regression coverage across the affected commands. Thank you @YunyunZhai — and thank you for your patience while this one waited for review.
