Session 954da1a9 asked for an eight-view web UI and shipped a Vite starter
page. Discovery settled all eight items in brief.scope; the analyst emitted
four criteria, all part="Project Foundation"; the architect planned against
that DoD, so the run scaffolded Vite, Tailwind and TanStack Query and stopped.
The plan-compile gate and the final reviewer both graded the shrunken DoD, so
a plan delivering 5% of the request passed clean.
Each DoD criterion now carries `covers`: the 0-based indexes into discovery
brief.scope it proves. A post-stage scope_coverage gate fails the analyst
retryably when an index has no criterion, handing back the dropped items
verbatim. Pure function of two recorded artifacts, so replay recomputes it and
no verdict event is needed.
Ceiling is index bookkeeping, not semantics: a criterion claiming covers:[3]
without really proving scope[3] still passes. It catches the silent collapse,
not a weak criterion.
