- mitm-handler-base: hookBufferStart returns InterceptedRequest with sanitized headers, extractSourceModel parses body.model, writeError emits JSON with sanitized message (Hard Rule #12). - mitm-handler-<id>: nine per-agent happy-path tests (antigravity, kiro, copilot, codex, cursor, zed, claude-code, open-code) exercise full intercept() with mocked fetch via _mitmHandlerHarness.ts; asserts mapped model is forwarded and AgentBridge correlation headers are present. Trae test confirms intercept() rejects with a structured error. - mitm-targets-resolve: ALL_TARGETS contains 9 entries; resolveTarget is case-insensitive and returns null for unknown hosts. - mitm-targets-route: bypass > target > passthrough precedence validated against representative hostnames. - mitm-detection: DETECTORS covers every AgentId; detectAgent never throws and returns DetectionResult-shaped objects for all probes.
