 - `GET /api/transform` exposes current process-wide reserved transform bytes and active slots alongside the existing counters.
 - 0.24.6 aggregate/decode bounds, allocation reductions and bounded cache/background workers remain in place.
 - The bounded transform-body collection path maps its boxed body error explicitly into `anyhow::Error`; source/release regressions reject the incompatible `.context(...)` form that was reported by an external compiler run.
+- A subsequent external Rust compile reached warning-only status and reported four lint warnings. The source now keeps the COLD transient read lease explicitly alive via `_read_lease`, names the RAII-only `TransientLease` field `_inner`, and removes the two dead CSS `last_char` assignments without lint suppression. Offline source/release regressions pin those shapes; a compiler-enabled rerun is still required to confirm a warning-clean build.
