Remove the 140-line Iteration 16 test section (commit 5d4e7b5) that
represented manually supplied checkpoint values as evidence of
target-scoped contribution behaviour. The section used extractLiveExperimentCheckpoint
to construct mock result objects simulating multi-episode state transitions
but could not observe contributions — the deterministic seam has no
contributions field in its return shape.
Preserves: all pre-existing checkpoint tests, Iteration 15 source-level
assertions, synthetic CU synthesis tests, and existing helper imports.
Add Iteration 16 test extension that documents the behavioral evidence
boundary for target-scoped contribution filtering:
- Observable via extractLiveExperimentCheckpoint:
* Node A pre-episode graph state (graphCheckpoint.nodeCount)
* B's fresh deconstruction trigger (providerGenerateCalls increments)
* Graph/findings continuity (reasoningState turnCount advanced)
- Blocked from deterministic seam (no contributions field in checkpoint):
* Historical contribution retention for non-current targets
* B contribution associated with targetNodeId
* Both A and B surviving in postEpisodeContributions
* B prep scope receiving B-specific contribution
Uses mock result objects to simulate the two-target sequence
(n_enterprise_customer_signing -> n_product_launch_decision) and
explicitly documents which assertions can and cannot be verified.
Historical contributions for a different Open Question node no longer
suppress fresh focused deconstruction of the current target. Only
contributions whose targetNodeId matches the current target are counted
towards suppressing redundant deconstruction.
