Add Format Specification section 21 (Scenario Model 0.1) and the runtime
that realizes it: the scenario director, seven trigger classes, timelines
with repeats and branches, admission and concurrency control, nested
ownership with bounded cleanup, and the production GC5 resource counters.
Exhibit E provides a reproducible forty-minute long-scenario reference and
scenario-challenge.xzbt covers the PRD 131 cases. A standalone
acceptance/soak page is built by tools/build-scenario-acceptance.mjs.
252 automated checks pass. The two-hour real-duration development soak
required by the GC6 schedule remains pending.
