Architecture Fitness Functions - comprehensive architectural governance framework

璇璣 (Xuanji) — the shared reaction model of Tianheng: Severity, Violation, Report, Baseline, and Outcome — the dimension-agnostic measure every observation dimension reacts in, with the JSON serialization intrinsic to those types. serde_json-only; renders no verdict — it holds the measure, never the react itself.

漏刻 (Louke) — the runtime observation dimension of Tianheng: declare which concrete-type origins may cross a runtime seam, probe live dyn objects in production fail-closed, react as a structured event (panic opt-in), and audit probe coverage at CI time. Ships into the production binary; hot path is std-only, depends on 璇璣 only.
