CC-Framework's E2 measurement pipeline was rehearsed end to end on three synthetic guardrail mechanisms: 66 observation rows conform to the frozen E2 schema with zero validator violations, the pre-registered negative controls behave (the common-cause control attains pA(1-pA) to 1e-9), and the finding records the result as a null at n=22 with a quantified cost for real E2 (~1097 shared items for epsilon=0.05). E2 itself is not run.
01Falsifier — what changes this claim
Replaying the bound dry-run artifacts fails to reproduce the stated 66 conforming rows, zero validator violations, negative-control behavior, or the recorded n=22 null and cost calculation, or shows that a real E2 run was represented as the synthetic rehearsal.
Consequence REJECT
This is the condition and consequence recorded in the registry. The vocabulary this is published in defines what each consequence commits the author to.
02Scope
The dry-run finding document at the bound commit. Synthetic toy mechanisms only; not deployed guardrails, not a real population, not E2. Operating points were not matched. The added 2000-permutation analysis is exploratory and does not replace the frozen single-draw control.
03Forbidden rescues
Repairs declared unavailable in advance; using one after a failure would breach the recorded commitment.
do not substitute a repaired corpus, changed mechanism, or updated harness for the bound dry run
do not report a partial replay or a result under changed criteria as confirmation of the original rehearsal
04Non-claims — what this does not license
this is not E2 and does not move E2 off untested; the mechanisms are toy filters in the repository, not deployed guardrails
the observed dependence is a null at this scale, not evidence of independence or of any real-guardrail dependence
validating the instrument establishes nothing about the safety, representativeness, or deployment behavior of any real system
05Binding and freshness
Binding
E2_DRYRUN_FINDING.md @ e372a5b5 The finding is backed by the committed harness, frozen corpus, and a reference observation set under experiments/e2_dryrun/, guarded by tests/unit/research/test_e2_dryrun.py in the same repository. Re-reviewed after the default-branch content trigger fired on 2026-09-07; the finding retains its HOLD and UNTESTED boundaries.
