"""VIOLET — staged rebuild of the PINK-on-DITAv2 runtime.

Stage V0: reactor clock primitives + latency harness (this package).
Stage V1: observe-only runtime scaffolding (observe_guard, divergence).

Charter: violet-subsecond-rebuild-plan (operator memory) — VIOLET is the
highest-frequency color in the visible spectrum; the runtime is the
fastest-cadence member of the BLUE/PINK family. The DITAv2 kernel, exec
router, venue adapters and persistence are SHARED LIBRARIES; only
launcher/identity/namespaces fork.
