Closes third behavioral-debt block from retro #8: CLAUDE.md §5 п.14 (graph-first для codebase-вопросов) was being ignored — controller did 4+ Grep searches today without consulting graphify.
Three changes:
1. tools/enforce-graph-first.mjs (NEW): Stop hook blocking turn-end when Grep+Glob count >= 3 in turn AND no graphify invocation (Skill 'graphifyy' / Bash 'graphifyy' / SlashCommand 'graphify'). Override: 'graph-skip: <reason>' inline OR global override-phrase. 19 vitest tests cover empty toolUses, threshold boundary, graphify detection forms, override variants.
2. tools/enforce-override-vocab.json: added 'graph-first' AND 'chain-recommendation' to suppresses[] of all 7 global override phrases (без скилов / direct ok / срочно / быстрый коммит / recovery / memory dump / ремонт инфраструктуры). This closes a vocab gap that ALSO affected the previously-deployed chain-recommendation hook (a3 from d1d53080) — global overrides did not work for it either until now.
3. .claude/settings.json: registered enforce-graph-first.mjs as 5th Stop hook entry.
Full vitest tools-sweep: 1041/1041 GREEN. Reviewer APPROVE on spec + code quality. Pipe-test verified (empty event → exit 0, no block).
