RQ2-P3 mechanism study (NEW prereg, approved-path/params-locked, not yet frozen):
pool-based willing-bridge instrument, concentration swept as a manipulated IV
(B∈{2,4,8}×α∈{0,1,2}), two-sided/direction-agnostic, run-level cluster bootstrap.
RQ3 companion run-brief (execution-freeze for the already-frozen RQ3): agent=qwen2.5:3b
local Ollama, churn kill_prob=30/steps=20, baselines + Holm-7 completion pinned.
note-unique-bridge-artifact.md: on-record analysis that the lead RQ2-P1 shrink is plausibly
a fresh-bridge-per-circuit artifact (unique exit-signature -> singleton set -> H~0), and that
realistic bridge reuse (a mix) may raise anonymity -> the mechanism study may qualify the lead
RQ2 headline. No edit to the frozen prereg or committed lead paper.
