- Compare tab: Work-style change list with a detail pane (Problem, Next step and
an A/B Compare section), Open in Work and Open in timeslot A.
- Security Domains A -> B over the sources compared in both timeslots, with
resolved against new-plus-regressed bars.
- Value changes for scanner findings: the Finding Reader's Problem values of
A and B (Result, Affected, Results rows, Expected, Found), shown side by side
and marked red or green like GPO configured values.
- GPO settings matched by Scope and Technical Identity; regressions carry their
passing A occurrence.
- Loading: shared reads per repository revision and a revision-bound report,
workspace and GPO overview cache in the comparison route.
Add the Comparison Engine read port, a Core-owned adapter that loads each
timeslot as Work reads it (scoped scanner runs, rolled-up GPO verdicts, backup
creation time only) and GET /projects/:id/timeslot-comparison with validation,
a concurrent-change guard and an off switch. The API client gains an
engine-free getTimeslotComparison and the activity label.
