Why: the library now defines requirement-level conformance for tool rules
and hooks (draft.8); the composition's existing gate mechanisms should be
honestly graded against A1-A7 rather than implicitly assumed compliant.
Evidence: matrix rows cite the 19/19 scratch suite negatives, the live data/
dirty-tree interception, and PR records; commit-msg python3 dependency
verified fail-closed by reading the hook's test path.
Impact: docs-only; guidelines gitlink advances to c9ab623 (draft.8); no
workflow or code change.
Refs: Development-Guidelines PR#2 (c9ab623); policy/adoption.md
Why: a running serve instance writes data/ into the working tree, which
trips the precheck SHARED_WORKSPACE_BUSY verdict for every later task.
Evidence: git status showed only untracked data/; runtime state is covered
by make clean and never meant for version control.
Impact: entry-doc only change; no tracked content altered.
