+Commit `9acd9bad` adds the analyst-facing presentation slice without changing the queue/case API or disposition CAS contract: queue items are grouped into `Needs investigation` and `In progress`, case pages lead with a business-language summary, evidence cards expose type/access state, and technical IDs/refs remain behind collapsed disclosures. Focused frontend proof is 13 tests with lint/build green and zero Axiom parse warnings. This does not close T027, T032, T033, `G-INVESTIGATION-UI`, or `G-BA-UX-READINESS`.

No agent chat/prompt/assistant editing/proposal generation/workspace/start/handoff controls. Runtime removal is OPEN, not performed by this spec refresh.
