docs(research): regenerate the artifact under the v2-mandatory harness

Supersedes the previous artifact, which predates v2_reconstruction becoming a
required variant and the P1-cap conditional reporting. Generated from a clean
tree (git_dirty false at rev 43ee619), all hard gates passing, so the recorded
source hashes actually identify the code that produced it.
