# Verification report - RustProxy 0.24.7

## Scope

RustProxy 0.24.7 makes transformation memory/concurrency limits configurable and adds persisted RAM saver, Recommended, Performance and Uber performance resource presets. The same version now exposes live transform resource usage, overview process/cache RAM accounting and COLD disk occupancy. It retains the 0.24.6 cache/background-worker memory hardening.

## Source contracts reviewed

- Transform `preset`, `memory_budget_bytes` and `max_inflight` are part of the normal revisioned Settings document and therefore persist in SQLite; the reopen test covers them.
- Existing configurations default to 128 MiB transform temporary memory and 32 concurrent attempts.
- New transform attempts use atomic runtime byte/concurrency reservations and fail open with fixed `memory_pressure` / `concurrency_pressure` reasons rather than queueing full-body work.
- Presets modify only resource limits; transform type switches and extension allow-lists remain independent.
- Global transform representation/eligibility settings participate in cache compatibility identity. Resource-only preset/budget/concurrency fields do not.
- OpenAPI and both language packs expose the new controls and preset states.
- `GET /api/status` exposes `transform_resources` and `memory_accounting`; the latter keeps process RSS separate from HOT/transient cache accounting and treats transform bytes as an overlapping conservative reservation.
- Cache runtime telemetry exposes COLD byte/object limits so the overview can show disk occupancy against configured capacity without mixing disk and RAM.
- `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.
