Deviation from baseline detected in 5 cells across 5 models this cycle — 5 above baseline. Detail below.

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. 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.
