 # RustProxy 0.34.0
 
+## DEV: OPT4 small-response proxy hot path (uncompiled sources)
+
+The compiled OPT3 binary passed 151 real HTTP acceptance checks (1 optional
+Zstandard case skipped). OPT4 removes avoidable allocations and string work
+for ordinary uncached HTTP/1.1 requests, with regressions for empty request
+bodies, URI/Host/Connection semantics and Unicode log truncation. OPT4 has
+**not been compiled or RPS-measured**. No settings or functionality disabled;
+version remains 0.34.0. Details:
+[`docs/PROXY_1KB_OPT4_DEV_0.34.0.md`](docs/PROXY_1KB_OPT4_DEV_0.34.0.md).

 ## DEV: small-response proxy hot path, OPT3 source candidate
 
 Seven compatible optimizations reduce path copies and work constructing
 forwarded headers, log IPs, hop-by-hop headers, request IDs and cache-off
 reason totals. HTTP/1.1 proxy with a 1,040-byte response remains the first
 benchmark priority; local Web Server is secondary. No version or policy changes.
-The **new code is not compiled or RPS-verified** here. See
-[`docs/PROXY_1KB_OPT3_DEV_0.34.0.md`](docs/PROXY_1KB_OPT3_DEV_0.34.0.md).
+A subsequently supplied compiled OPT3 executable passed 151 real HTTP
+assertions (one optional codec skipped). Two short same-host benchmark runs
+did **not** establish a stable RPS gain over OPT2. See the historical
+[`OPT3 source report`](docs/PROXY_1KB_OPT3_DEV_0.34.0.md)
+and the newer [`OPT4 analysis`](docs/PROXY_1KB_OPT4_DEV_0.34.0.md).
