The working pattern was already high months before the platform transition. A 344-turn strategy thread from November 2025 scored 5.83 composite — well above tactical baseline — and the substantive data-work threads from January–February 2026 sit between 5.2 and 5.7. These predate the standalone Claude work entirely. The pattern was forming through real intellectual work, before any acute event forced reflection.
April is a bimodal spike, not a uniform peak. Mean drops to 5.81 because the volume of tactical drafting threads dilutes the average. But the max climbs to 8.33 — the post-exit processing thread, the brand banner work, the identity reflection, the cross-tool review, the website build all score in the 7.5–8.8 range. Two kinds of work happening simultaneously: tactical reconstruction (low scores, high volume) and strategic-identity rebuild (high scores, lower volume).
The Claude sessions sit at the top of the corpus. Claude composite scores range from 5.0 to 8.83, with most clustering 7.0–8.8 — higher than the GPT max line for most months. This supports the central claim: Claude has been where substantive intellectual work concentrated, not where the working pattern was built.
The transferred-not-developed thesis holds in the data. If maturity had been built on Claude, you'd expect the GPT max line to be lower than the Claude scores by a meaningful margin. The chart shows the GPT max line reaching 7–8 well before the late-April platform transition, and the Claude scores starting at that level rather than climbing toward it. The working pattern walked in on day one.
Phase 1 continuation (May 15 → Jul 30, 2026 · added Jul 31). 14 additional Claude threads scored on the 6-dim rubric to close the freshness gap that existed at Phase 1 end. Range: 5.83 (agentic AI coursework module) → 8.5 (this audit thread). The pattern from earlier holds: substantive Claude work continues to cluster 7.0–8.5, with the deepest meta-work (audit, Gather hub, DAD Phase 0) at the top of the corpus. The audit thread itself scores 8.5, driven by high meta (9) and high pushback (9) — the operator pushing back on the scorer multiple times mid-flight is exactly what the pushback dimension is trying to measure.
The July shape is consistent with the Phase 1 trajectory. No drift down; no artificial climb. The Claude corpus for May–July looks like a natural extension of the pattern established in the early Claude weeks. Governance instrumentation (this audit) sits at the top of the curve, which is where you'd want it to sit if the practice's own USP claim (governance discipline) is real.
