 - Prompt includes revised Rule 2 boundary text ("Do not introduce or describe open questions...")
 - Exactly one synthesis invocation per run
 - Input fixture is not mutated (deep clone + compare)
- No persistence/Supabase/DB operations

+Source: authenticated GET `/api/investigations/6b080d97-033e-477b-9d41-7b2f4f04bbed` (2026-10-08)

+Contract: `{ situationGraph: object, findings: array }`
+
+Contents:
+- `situationGraph`: 11 nodes (1 state, 5 observation, 2 metric, 3 unknown), 10 edges, full `reasoningState`, `resolvedNodeIds`, `centralStatement`, `activeUnknownNodeId`
+- `findings`: 9 findings total; all 7 previously verified IDs present (`hciikc`, `ybfsm3`, `k45vyt`, `vhftyr`, `9bgkmw`, `23192q`, `kkh39k`)
+
+Verified: helper parses without invoking live synthesis; fixture immutability confirmed via deep-clone roundtrip.
