Post-seal, un-blinded fill of the RQ2-P3 mechanism track in the combined
companion paper (D3), matching the lead paper's post-seal discipline. RQ3
remains fully HELD-BLIND (battery still running; progress read by sidecar
count only).
- §3: FREEZE-PENDING -> FROZEN 2026-07-21 (prereg SHA 8db4e8a7...)
- §5 Results (RQ2-P3): H1 rho=+0.6244 CI[+0.5941,+0.6545]; H2 slope=+0.7052
CI[+0.6195,+0.7903] (n=270, run-level cluster bootstrap); H3 RESOLVED=MIX;
Holm own {H1,H2} both reject. Effect+CI, never bare p.
- §6 Discussion: shared-pool concentration RAISES anonymity (mix), refuting
the naive funnel; honest qualification/correction of the lead RQ2-P1
"shrink" as a unique-bridge (fresh-bridge-per-circuit) artifact, per
note-unique-bridge-artifact.md + frozen mechanism prereg. Mandatory
disclosure: §7 dry-pass previewed direction (rho 0->+0.838); hypotheses
were pre-committed two-sided.
RQ3 Results/Discussion and the authoritative Holm-7 stay HELD-BLIND until
rq3-battery-results.json lands. Lead RQ2-P1 + frozen lead prereg untouched.
