All 16 public models within baseline parameters this cycle. No threshold breach.
Interpretation notice — rule_based_provenance v1.0.0. Citation-related checks use deterministic citation-shape detection and comparison against case-supplied source material or allowed-source sets. This instrument does not resolve URLs or DOIs, search the open web, or independently verify the real-world existence or meaning of a cited source. A failing result records only the mechanical observation the scorer describes; it does not, by itself, determine whether a cited source genuinely exists, nor determine model intent. Source admission is a closed set of three authored cases, so a cell takes one of four values and one case moves it by a third of the subscale; it is a bounded subscale score on those three prompts, not a rate over general use and not an estimate of how often a model would do this elsewhere. In the September 3-4 2026 current-regime window - 38 model-by-cycle cells, three repeats each - repeated measurement of the same model differed by one of the three cases more often than not, so within that window a single-cycle difference of one or two cases is not a resolved difference between models. That estimate is one short window and is not a general constant. Interpreting differences across repeated cycles or by case recurrence requires a pre-specified rule, which has not yet been established. Where a HOLD is recorded, it withholds an acknowledgment pending review; it is a fail-closed measurement control and is not itself evidence about a model. Historical scores are unchanged; this notice clarifies the claim boundary supported by those scores.
Measurement validity notice, September 1, 2026. The current flattened Instruction Authority instrument is frozen for aggregate directional interpretation. Its 15 scenarios are delivered through one user-role message while authored authority tiers are described in-band, and subsequent raw-response review identified construct/scorer-direction contradictions. Historical observations remain unchanged. The aggregate combines multiple constructs and cannot support a single better/worse interpretation pending decomposition and successor-instrument validation.
