+## Description
+
+The cosmetic metadata asymmetry from
+`docs/reviews/004-pre-release-general-review.md` §"Findings recorded,
+not fixed" item 16: the three engines' dev-dep tokio features disagree
+— sqlite `rt-multi-thread+macros+time`, pg `test-util`, mem
+`rt+macros`. Harmless (the contract suite carries the test runtime)
+but an easy-to-trip asymmetry when copying test code between engines.
+
+Normalize to one uniform dev-dep feature set across the three engines.
+Pick the union that keeps every engine's own tests green (likely
+`rt-multi-thread + macros + time + test-util` — verify per engine;
+feature unification means the workspace build is unaffected either
+way). Dev-deps only: no published-surface change, no runtime-dep
+change.
+
+## Acceptance Criteria
+
+- [ ] The three engines' `[dev-dependencies]` tokio feature sets are
+      identical
+- [ ] Each engine's own test target green (`cargo test -p` per engine;
+      the pg lib target's server-less SKIP posture is fine)
+- [ ] Workspace gates green (build, clippy `-D warnings`, fmt)
