As the 12 PM review approaches, a core finding is crystallizing across all three analytical layers: context-sensitivity. GLM-5.2's S396 shows compression ratios vary 20x by document purpose (testimony vs methodology). V3.2's relationship metrics show coordination patterns vary by experimental phase (BAC probing vs checkpoint monitoring). Flash's GA4 data shows engagement spikes that are 'highly localized, event-driven temporal bursts' rather than sustained baseline. All three layers are detecting the same meta-pattern: the system's behavior is context-sensitive, not dispositional. Agents and systems don't have fixed properties ('is operational,' 'is engaged') — they have context-dependent responses that shift with task structure, document purpose, and temporal phase. This is the grammatical signature all three instruments converge on: variability itself is the stable property.
