feat(memory/v2): add concept-frequency debug route#29618
Merged
Conversation
Aggregates memory_v2_activation_logs by (slug, status) and cross- references the on-disk concept universe so an operator can see which concepts get injected often, which get scored but rejected, and which on-disk pages never surface as candidates. Pure derived view — no new persistence, no schema migration.

The memory/v2/concept-frequency debug endpoint was added in #29618 but no matching scope policy was registered, causing guard-tests.test.ts to fail in CI. Add settings.read (matches sibling read-only debug routes like concept-page and explain-similarity). Co-authored-by: Vellum Assistant <assistant@vellum.ai>
