# CIR gold-label validation gates — computed and countersigned, 10 August 2026

Gold labels: 3,218 two-coder consensus items + 232 Opus-family adjudicated items
(6 resolved to third labels). Gates computed mechanically per the registered frames
(exact Clopper–Pearson 99% LCBs; class floor 250; cross-corpus 99% UCB on the
accuracy difference; the derivation script's stdout is preserved verbatim in the
countersigning commit's tree as the audit trail).

| proxy | gold+ | gold− | abstain | sens (LCB99) | spec (LCB99) | floor | GATE |
|---|---:|---:|---:|---|---|---|---|
| PXY-01 genre (funerary-or-votive) | 358 | 284 | 108 | 0.9860 (0.9638) | 0.9789 (**0.9495**) | OK | **FAIL → PARK** |
| PXY-02 material (stone) | 417 | 168 | 165 | 0.9209 (0.8847) | 1.0000 (0.9730) | **neg 168 < 250** | **FAIL → PARK** |
| PXY-05 crude bracket, EDR arm | 355 | 394 | 1 | 0.9859 (0.9635) | 1.0000 (0.9884) | OK | **PASS** |
| PXY-05 crude bracket, EDH arm | 385 | 365 | 0 | 0.9896 (0.9702) | 1.0000 (0.9875) | OK | **PASS** |
| PXY-05 cross-corpus | | | | acc 0.9933 vs 0.9947 | diff UCB99 = 0.0179 | | **PASS** |

## Rulings

1. **PXY-01 fails by 0.0005 of LCB and the gate does not round.** The registered
   criterion is a 99% lower bound ABOVE 0.95; 0.9495 is not above it. The point
   estimates are good (98.6/97.9) — and that is exactly what the demonstration-style
   gate is for: good-looking is not demonstrated. PARK per protocol condition 12; no
   tuning, no relaxation, no resampling.
2. **PXY-02 fails twice over** — the gold-negative class lands at 168 against the
   registered 250 floor (undecidable at registered power ⇒ PARK, never relax), and
   sensitivity's bound (0.8847) confirms from the gold side precisely what Lane A
   proved from the vocabulary side: the frozen material classifier misses real stone.
   Convergent, independent, sealed-from-each-other routes to the same defect.
3. **PXY-05 VALIDATES, both arms, with cross-corpus invariance.** The crude bracket
   method is a valid detector of Leiden markup in the text it is given, on both
   corpora. This coexists with, and sharpens, the format finding: the adjudicator's
   packet-level discovery that EDR's staged edition text arrives with restored spans
   STRIPPED means the field itself is impoverished — a valid detector applied to a
   depleted input. The detector passes its gate; the staging extraction goes to the
   fix ledger as a new repair candidate (Leiden serialization from structured markup
   is specification-determined).
4. **PXY-06 fails decisively** (sensitivity 0.60 against a 0.95 bar), converting the
   results-consult's "unvalidated semantic proxy" into a measured invalidity. The
   abstention profile (117/450, driven substantially by critical-edition scans in the
   image corpus) and the 80 mixed-signal exclusions publish beside it.
5. **Abstention-defect adjudications** (the 10% line): triggered for PXY-01 (16.9%
   coder-1 / similar coder-2), PXY-02 (~22%), PXY-06 (~33%). Adjudication: the
   drivers are evidence-structural (source-recorded "ignoratur" terms; edition-scan
   images), not codebook defects — the frames performed as designed, and the rates
   publish with the gates.

## Consequences for the replication (park list, per protocol condition 12)

Analyses consuming a failed proxy PARK in the re-execution: **09-grok-r1** (genre +
material), **09-grok-r2** (genre), **18-grok-r2** (gap/supplied). Analyses free of
failed proxies RE-EXECUTE under the fix ledger: 02-codex-r2, 02-grok-r2, 03-grok-r2,
06-codex-r3, 14-codex-r2, 18-codex-r2 (its validated crude-bracket detector, with the
staged-text depletion question ledgered), and the Pattern-3 triangulation arm. The
alpha verdicts for the parked three remain the published record, carrying their
post-result assessments; the corrected-instrument delta for them is DEFERRED to a
future frame with repaired evidence, and says so.

Countersigned: Claude (orchestrator). Next: fix-ledger assembly with the bundle open.
