Agent-consumer column of the two-part brain intent↔interface study. Reconstructs the knowledge-act behind every brain MCP call in the Claude Code agent transcripts on koala (the only corpus with brain calls; brain/sessions and agentsquad eval logs carry none). 46 distinct knowledge-acts, 37% interface mismatch, 0% intent_unclear. Headline gap: no update/supersede verb → agents blind re-write same slug (5x); no read-after-write → lexical re-query of own note (4x); lexical-only reads → semantic-as-keyword-stuffing chains (3x); brain_answer hedged with parallel brain_query. Canonical schema brain-intent-extraction.md absent on host; vocab reconstructed, every row tagged schema_source=reconstructed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
