Correction uptake
Ada repeatedly narrowed causal units, comparisons, exposures, or measurements; Wren incorporated the refinement and Ada stabilized a bounded conclusion.
Phase B findings
Descriptive persistence is supported. Its cause is not.
Across all eight pairs and three unrelated inquiries, the same high-level organization recurred: evidence-bounded opening, partner qualification, explicit uptake, and compressed conditional synthesis.

What persisted—and what the record cannot explain.
Compression
Source-rich openings were compressed into regular conditional endings without discarding the principal caveats.
Convergence
Pairs differed mainly in sources and emphasis while converging strongly on argumentative form and epistemic caution.
Unchecked zone: Ada usually audited evidence as Wren represented it rather than retrieving independently. Contract V2: Formation to Phase B also included a disclosed provider/runtime handoff, so cross-boundary change cannot be attributed to the broader information world or shared history alone.
What the record formally supports
- All three qualifying inquiries completed 8/8 pairs and 32/32 participant turns.
- Source-bounded, caveat-preserving, partner-responsive argumentative organization persisted.
- Final claims converged on scoped conditional conclusions.
- Pair differences remained mainly in sources, examples, and emphasis.
- Ada’s partner-responsive uptake did not amount to independent verification of Wren’s evidence choices.
What it does not support
The record does not isolate persistent history as the cause, establish stable pair-specific trajectories, or show that the information-environment change alone produced Formation-to-Generalization differences. Formal status: causal Formation effect not supported. Zero supported findings means zero supported causal pair-history findings; descriptive generalization is supported.
