-### Align scope with evidence and close durable-run and variant gaps

 ### Generalise the model and settle the open questions
 Progress: 5/8 done  |  workplan_id: `36a082df-1288-567d-9a0b-f2e0f292786c`
 
 **Open tasks:**
 - ! Bounded live-model runtime experiment  `0090ce51`
-  *(wait: Bernd Worsch must select the model, fixed run count, spending ceiling and default-suite policy before any live-model experiment. No paid calls were made.)*
+  *(wait: Bounded live-model experiment: run count and cost ceiling agreed with the operator before the first call.)*
 - ! A browser-engine driver, if it is warranted  `19f8e687`
-  *(wait: Await the existing Playwright setup/licence decision and T01 prerequisite; T02 and T03 are now complete.)*
+  *(wait: Operator establishes Playwright and clears its licence.)*
 - ! Measure the cost of expressing a use case  `62f08e27`
-  *(wait: Initial timer excluded code composition; elapsed authoring cost cannot be reconstructed. Need a prospectively timed fresh implementation by an independent author using the specified contracts, not copying the fixtures.)*
+  *(wait: Measured only when T02's new use cases are written.)*
