Train the pathway, deposit the computation: a two-probe dissociation of component ownership in transformer emergence — code and data (v1.5.3)

Reproducibility archive for the two-probe dissociation study of component ownership in transformer emergence (synthetic Boolean degree-staircase + induction logs). Experiment code and per-run result logs only; manuscript sources not included. Code: MIT; result logs: CC-BY-4.0. v1.5.3: removed internal manuscript-series / process-artifact labels from README, claim map, and source comments; redacted multi-paper redteam status JSON; scrubbed sibling-series prose in the pilot runbook. Use this version (or later) for review; do not use v1.5.2 or earlier. GitHub tag v1.5.3: PeterPonyu/architecture-staircase.
