 Coverage floor is **89%** (measured ~89.7%). Headroom is deliberately thin, so a
 sizeable untested addition fails the gate rather than quietly eroding the suite.
+The measured set includes `app.py` (QUAL-009); it sits at ~76%, which is the main
+reason the headroom is as tight as it is. `Dependencies/` and `migrations/` remain
+unmeasured on purpose - the first is an interactive credential helper, the second
+is hand-written migrations that the Alembic drift guard covers instead.
 `pre-commit` hooks are **non-rewriting**
 (check-only, no `--fix`) so commits stay author-reviewed.
