B-8YI7-precommit-hooks-consult-quality-baseline
Status: promoted/task
During parallel task-work, lefthook’s project-check-docs-drift (pre-existing T-QFTI epic site page) and project-check-task-state-origin (sibling branch’s state commits visible on shared local main) block every main-commit and worktree commit, forcing —no-verify. The quality gate has a baseline to subtract pre-existing drift; the pre-commit hooks could consult the same baseline or scope drift to changed entities so contributors aren’t forced to —no-verify past unrelated trunk drift. Surfaced by T-KESH post-mortem.
