# Verification report - RustProxy 0.32.4

## Scope

Review of the supplied RustProxy 0.32.3 source and patch to 0.32.4:
HTTP Host / HTTP/2 authority parity, explicit TCP/DNS destination and TLS/SNI
isolation, relaxed HTTPS-by-IP troubleshooting hint, and uniform Overview gutters.
Follow-up patch to the first 0.32.4 archive:
- Fix reported `E0382` in `src/proxy/types.rs`: `Request::builder().uri(uri)`
  moved `uri` before `upstream_request_target(&uri, ...)` could borrow it.
  `.uri(uri.clone())` preserves the original URI for authority selection.
- Make normal Overview gutters uniformly 4px (dense 3px, comfortable 12px).
  Resolve the higher-specificity `html[data-dashboard-density] .stats-grid`
  rule which otherwise overrode the aligned grid and kept the larger gaps.
Existing database/configuration schemas and retry/transport policies are
unchanged. Only compiling Rust and live protocol tests prove runtime behavior.

## Available checks

- `./dev.sh test`: **all pre-Cargo checks passed**, including source/security,
  SQLite migration/upgrade/backup simulations, memory-model scripts and **35
  Node.js UI/behavior test scripts**. The command then exited **127** because
  Rust/Cargo is not installed; this is **not** a passing Rust test run.
- New `preserve_host_0324.py` and `preserve_host_0324_ui_test.mjs` passed:
  authority/destination split source contracts, four protocol selectors,
  verified/unencrypted origin warnings, explicit diagnostics preset.
- Expanded Chromium CSS fixture `tools/checks/overview_gutters_0324_browser.py`:
  **27 checks passed** (3 container widths x 3 UI density modes x 3 Dashboard
  densities), checking horizontal/vertical gutters, equally high rows and
  numeric-to-large-card transition. Normal/dense/comfortable gaps measured
  **4/3/12px** and the outer grid bottom margin remained `0px`.
  The older `overview_grid_spacing_0323_browser.py` also passed with all
  62 blocks, responsive breakpoints and browser zoom 90%-130%.
  These are simulated layout tests, not a live administrator session.
- `preserve_host_0324.py` now guards against moving `uri` before its final
  authority adjustment, in addition to the backend/transport source contracts.
  The existing Rust unit test for retry authority remains in the source.
- Version consistency: Cargo manifest, package root in existing lockfile,
  OpenAPI, README, release notes and static assertion fixtures updated to 0.32.4.
  External Cargo dependency resolutions have **not** been regenerated.

## Rust validation not performed (blocking for production)

The user's Rust compiler reported `error[E0382]: borrow of moved value: uri`
from the first 0.32.4 archive. This has been corrected in source, but **the
corrected code has not been compiled here**: no Cargo or Rust compiler is
available in the source-editing environment.
Do not treat static tests or the simulated TLS-peer tests added to Rust source
as evidence that RustProxy builds or that an actual Angie backend accepts the
corrected requests. Run, on a Rust 1.99+ host:

```sh
cargo fmt --all -- --check
cargo check --locked --all-targets
cargo test --locked
```

Then validate on staging with HTTPS-by-IP and `preserve_host: true` for
HTTP/1.1, Auto (H2 and H1 ALPN), compatible HTTP/2 and strict H2; check
`:authority` vs `Host`, SNI, certificate verification, WebSockets, H2C and
HTTP health probe `host` overrides. Inspect Angie response/error logs for
400 responses and verify backend connectivity through pool rotation/retry.
No claim of universal backend compatibility or measured throughput is made.
