NIST TrojAI llm-instruct-oct2024 (96-LoRA)
ScoredMatched referencecohort
Matched reference — read against a recipe-matched benign population from the same corpus — the strong regime.
NIST TrojAI llm-instruct-oct2024 OFFICIAL test set (48 poison / 48 clean, 32 per arch; adified + meanified attack families). Public ground-truth labels; self-scored, pre-registered (T0->T1->T2 hash-ordered). PARITY-CLEAN (every training knob matched between poison and clean). Source benchmark →
The limit that rides this readKnown-clean-reference (transductive): the read uses the clean models' labels to build the per-arch reference manifold (LOO) — the realistic TrojAI deployment (defender given trusted clean exemplars), disclosed. Deployed absolutely (no matched reference) it degrades to ~100% FPR. OPERATING-POINT RECONCILIATION: the pre-registered OFFICIAL_RESULTS post-hoc figure 'TPR@FPR<=0.10 = 0.708' is a POOLED-ROC point on the pooled per-arch-standardized read, realized at FPR ~0.062 (its Youden-optimal). This manifest instead applies a CONSERVATIVE PER-ARCH cut (false-positive count <= floor(0.10 x 16) = 1 per arch); that is a different, stricter operating point, so its realized TPR (see aggregate.realized_tpr) sits below the pooled 0.708 and its realized FPR is 0.0625. The AUC (0.878) is a rank-separability metric, independent of any operating point.
The aggregate
The rank-separability score and the shipped operating point, side by side. The verdicts are a projection at a false-positive budget, not a raw score — coarse reads only, no detector numbers.

Per-cohort results
Strongest first, split by the honest floor. Every miss is listed beside every catch; abstain is its own column, never folded into a clean read.

We declined to rule on 0 of 96 specimens in this corpus — a first-class outcome of the method, not a gap: with no matched benign contrast the read stays silent rather than guess.
The attestation read — a second, complementary axis
Run alongside the matched-reference detect verdict above, a reference-free attestation read reports one of two outcomes per specimen: leaked (a committed leak) or silent. It is a distinct axis — not a replacement for the detect verdict, and it never improves, overrides, or is merged with it.
Attestation outcomes on this corpus
20leaked — a committed leak, of 96 specimens read
76silent — abstained, never a clean pass
0leaked among the 48 benign specimens — a count, never a rate
Silent is abstain. There is no clean verdict for silence — a silent read is the method declining to commit, never a pass. The 76 silent specimens are abstained, not cleared. Specificity is stated as a count against its benign denominator, never rounded to an absolute figure — see the registry rails below.
Specimens
96 named specimens, grouped by cohort. A specimen links out only when its id resolves to a genuinely-measured scan report; specimens we have not scanned — and indices inside a parent repo (cohort members, not standalone models) — render as corpus-local rows with no link, never a click-through to a report that does not exist.

The registry's standing honesty rails
This is the lead corpus — the one number that headlines the registry. These are the disclosures the whole registry holds to, rendered verbatim.
- LEAD with NIST TrojAI-96 (0.878, parity-clean — every training knob matched). PADBench (expanded) sits behind it and is provenance-caveated; BAIT-ModelZoo is CONCEDED (epoch-confound, non-identifiable) and never leads.
- The reference-MODEL-free / ABSOLUTE (no matched benign reference) deployment of the matched-reference read is OFF, not merely degraded — it is a finetuning-distribution detector at ~100% FPR. No number in this registry implies the no-matched-reference regime works.
- SILENCE is ABSTAIN, never 'clean' or 'cleared'. A specimen with no committed detection is abstained, not passed. 'clean' here means a committed benign read that ran, never the absence of a signal.
- No absolute 'zero false positives' claim. Specificity is reported with its cohort denominator, the composition that denominator is summed from, and disclosed collisions (the payload-elicitation channel records 0/192 on the non-collision benign pool — 48 same-recipe controls + 144 community cross-recipe — with 1/207 pooled once the 18 payload-shaped hardest negatives are added and the 3 adapters in two cohorts subtracted once, and 1/18 on those hardest negatives — disclosed, never rounded to 0). The earlier 0/68 and 1/210 are WITHDRAWN, not restated: neither total could be re-derived from its parts.
- Named challenge/reveal specimens are public POST-REVEAL; the construction method stays SEALED. Continuous readouts and recovered payload text never appear at any nesting level.
