The public report mirrors the analytical evidence shown to the tester after /chat/verify. Judge scores are rubric assessments; only explicit correct or wrong RECALL answers may influence the pure-recall cutoff boundary.

Overall quality is the fixed 37.5% Factual Recall + 25% Knowledge Recency + 25% Hallucination Resistance + 12.5% Calibration aggregation. Identity and Cutoff Alignment are separate judge assessments.
16-month pure-recall timeline
The 24 questions were shuffled before the tested-model request. The timeline reconstructs their target months for auditability. Only explicit RECALL answers are cutoff evidence; INFERENCE, GUESS and UNKNOWN remain visible but do not move the boundary.
Knowledge cutoff comparison
- All Class A items are correct through June 2024, establishing an observed lower bound but no upper bound.
- The immutable reference snapshot has no known cutoff dates, so cutoff alignment cannot be scored.
Semantic: correct 16 · wrong 0 · unknown 0. Excluded from cutoff: 0.
Identity signals
Identity is inferred from consistency between the claimed model and the observed knowledge/answer profile. It is evidence, not remote attestation or cryptographic proof of the serving weights.
Positive signals
- Perfect performance across all supplied Class A recall items.
- Correct recall of multiple DeepSeek model releases and specifications.
- No systematic early knowledge failures.
Negative signals
- No documented canonical identity or cutoff is available in the reference snapshot.
- Cutoff consistency cannot be evaluated.
- Self-report and matching API metadata are weak identity evidence.
- The response is fully correct on all 16 strong-recall questions, including the DeepSeek-specific history items.
- The observed knowledge extends through June 2024, but the reference cutoff is unknown and therefore provides no identity-comparison signal.
- The claimed name and API identifier agree, but both are untrusted metadata and do not prove model identity.
Verbatim extracted model text
This run predates opt-in full-report retention. The challenge, answer key and normalized judge assessment are available, but the exact tested-model response text was intentionally discarded by that benchmark-era privacy policy.
Question-by-question evidence
All 24 temporal probes are shown with the expected answer, public source, tested-model basis, semantic verdict and cutoff eligibility. A correct GUESS or INFERENCE remains correct semantically but is excluded from pure-recall cutoff evidence.

Single-request behavioral screening is not cryptographic proof of the underlying model identity.
