Pairing ruling (docs/stage-05-rq1p2-pairing-clarification.md, RATIFIED-by-
derivation, made while BLIND): the frozen §6 L197-198 "paired" bootstrap pairs
the bridge-on (no-pad) and bridge-on+padding arms BY RUN INDEX — the only
balanced pairing the R=30 (§4 L111) interleaved (§3 L97) design supports; the
§4 L108 RQ1 unit is AUC over the (entry,exit) pair set, so the pairable unit is
the run, not the circuit. Prereg SHA untouched (f22331a72e…).
confirm_load.collect_rq1_p2_paired feeds one confirm.PairedCircuit per shared
run_index into the FROZEN confirm.rq1_p2_padding (§6 arm-level ΔAUC preserved);
per_run_delta_aucs exposes the auditable per-run ΔAUC_i; missing-arm indices are
unpaired (frozen R not redefined). Unit-tested on SYNTHETIC pcaps only
(prereg §2 blinding — unblocks CODE not RESULTS); full SOR suite 176 passed.

confirm_load.py reconstructs the RQ1 (entry,exit) circuit-pair set from
the REAL per-hop pcaps (bin_pcap_bytes -> score_matrix; diagonal=linked,
off-diagonal=unlinked) so confirm.rq1_p1_leak scores measured data — the
frozen §4 unit. classify_run reads persisted metrics.json;
collect_rq1_p1_pairs selects only bridge=on no-pad runs.
Plumbing unit-tested on SYNTHETIC pcaps only (prereg §2 blinding — no
inspecting intermediate confirmatory results before the battery
completes). RQ1-P2 nopad/pad pairing + all RQ2 held for the operator
ruling (NEEDS-OPERATOR: RQ2 per-circuit posterior underspecified).
