The MCP complexity hint (`X-Grob-Hint` header, `metadata.grob_hint` body field, or one-shot MCP tool slot) was resolved and then dropped via `let _ = grob_hint`. It now overrides `RouteDecision.complexity_tier` right after routing, so clients that know their task is trivial can opt out of `[[tiers]]` fan-out for a single request.

Two drift fixes caught by Tier 2 audit (items #6, #14): - `src/routing/classify/mod.rs`: the `route()` doc-comment listed only 6 priority levels while the actual code has 9 (auto-map, declarative tier match, and algorithmic scoring were missing). The inline numbering also had a gap (skipping #7 and duplicating #9) — renumbered to match. - `docs/explanation/architecture.md`: the request-flow mermaid still showed the pre-T-VS `router` subgraph and a single generic "Circuit Breaker" box. Updated to reflect the `routing/` parent module (classify + circuit_breaker + health_check) and the RE-1a / RE-1b split from ADR-0018, including the `is_endpoint_healthy` AND-gate and the security-layer global CB that runs after it.

Summary
Two quick wins from the Tier 2 audit, bundled because they share the dispatch/routing scope.
DD-1 — audit #5:
