Sprint 2 unified-master-audit closure. Pre-fix four service List
endpoints (target, issuer, team, agent_group) called repoFoo.List(ctx)
to fetch the full table then sliced in memory:
rows, _ := s.repo.List(ctx)
total := int64(len(rows))
start := (page - 1) * perPage
end := start + perPage
return rows[start:end], total, nil
This page-sliced in memory pattern marshals every row per request —
fine on small fleets but unacceptable for multi-tenant or large-fleet
deploys. The agent_group case was worse — the service explicitly
ignored page/perPage and returned the entire slice.
Fix:
- New ListPaginated(ctx, limit, offset) method on each of the four
repositories. Postgres implementations push LIMIT + OFFSET into
the SQL plus a SELECT COUNT(*) for the total. Mirrors the cursor
pattern already in internal/repository/postgres/certificate.go.
- Each ListPaginated normalises limit≤0→50 and offset<0→0,
matching the service-layer defaults that already existed.
- Repository interfaces grow the new method so adapters stay
swappable.
- Service List methods now call repoFoo.ListPaginated(ctx, perPage,
(page-1)*perPage) directly — no more memory-slice.
- AgentGroupService.ListAgentGroups closes the Bundle E / Audit
L-020 'page/perPage unused' gap.
Test changes:
- sliceWindow generic helper in testutil_test.go mirrors the SQL
LIMIT/OFFSET semantics for in-memory mocks.
- Six mock implementers (lifecycle_test, testutil_test x2,
agent_group_test, team_test) gain ListPaginated methods.
- TestTeamService_List_SCALE002_PaginationPropagatesToRepo pins
the page=2, perPage=3 → 3 rows of 10 invariant.
Closes SCALE-002.
