1"""Integration tests for M5/A9 request_pipeline: the end-to-end composition entrypoint.2 3answer_question() wires the locked modules per LLD §3.1/§3.2/§3.3 with a FAKE provider (no real4model, $0). The load-bearing assertions: a happy-path scalar/aggregate yields a grounded5AnswerEnvelope whose value+provenance are stapled from the ToolResult; out-of-coverage abstains;6a hallucinated tool name / raw-query param is a typed rejection BEFORE execution; and a7model-down outcome at EITHER LLM stage degrades to a typed ModelUnavailable — NEVER a fabricated8AnswerEnvelope (INV-A6). No prompt produces an ungrounded fact (the SUITE-adversarial intent;9the full suite is JOIN-3).10 11```text12spec traceability (audit map — safe to skip)13LLD §3.1 (happy-path scalar), §3.2 (aggregate), §3.3 (rejection/abstention placement), §714TechSpec §4 (ModelUnavailable degrade;
