Pre-registration: LLM Judgment Probe for Construction-Sensitivity of English Countability

Pre-registration for an LLM-based acceptability judgment probe testing whether the dissociation hierarchy for English countability shows construction-sensitivity (existential vs agentive frames). Includes: prereg document, stimulus set (128 critical + 48 fillers), analysis pipeline (R/brms), runner script (Python). Fake-data validation confirms the design detects a 0.8-point interaction. Filed before any model is queried. Associated paper: Reynolds (in prep), The Homeostatic Maintenance of English Countability. GitHub: https://github.com/BrettRey/countability-hpc
