1. Fix test expectation: change && to & in m3u8 rewrite test
2. Add TestHLSPlayStream_ServeByBackend_HeadersCopiedFromBackend to
verify backend headers reach the client for m3u8 responses
3. Add TestHLSPlayStream_ServeByBackend_TSHeadersCopiedFromBackend to
verify header copy for .ts file responses
4. Add TestHTTPFlvTsConn_ServeByBackend_HeadersCopiedFromBackend to
verify header copy for FLV/TS streaming responses
These tests protect against regression where calling WriteHeader() before
Header.Add() causes headers to be silently discarded by Go's http.ResponseWriter.
1. Move WriteHeader() after setting response headers. In Go's
http.ResponseWriter, headers set after WriteHeader() are silently
ignored, which caused all backend response headers (Content-Type,
Cache-Control, etc.) to be lost during HLS proxying.
2. Fix double ampersand (&&) in m3u8 ts URL rewriting. When the
original ts URL already contains query parameters, the proxy
generated malformed URLs like ".ts?spbhid=xxx&&token=abc"
instead of ".ts?spbhid=xxx&token=abc".
- Fix a goroutine leak on the WHEP path: the backend→client reader was
being spawned on every inbound client packet (STUN keepalives + RTCP
feedback), leaking tens of thousands of goroutines under steady-state
load. Now spawned exactly once per connection via `sync.Once` on both
the RTC and SRT proxies. Listener and reader receive buffers are also
reused across iterations.
- Make the legacy SRS `/rtc/v1/play/` and `/rtc/v1/publish/` APIs work
end-to-end through the proxy. Those endpoints wrap the SDP in a JSON
envelope (`{"sdp":"v=0\r\n..."}` where `\r\n` is the literal 2-byte JSON
escape, not real CRLF), so ICE parsing previously absorbed the rest of
the body into the ufrag. Added `unwrapSDPEnvelope` for ICE extraction
and tightened `ParseIceUfragPwd`'s value class to stop at `\`. The bytes
forwarded to the client and the in-body candidate-port rewrite still
operate on the raw envelope.
- Enable `net/http/pprof` endpoints when `GO_PPROF` is set (blank import
in `internal/debug/pprof.go`) and add `docs/perf/proxy-whep.md` walking
through CPU/alloc/heap/goroutine/trace collection and `pprof -base`
before/after diffs for the WHEP workload (1 publisher + N players).
- Tighten `SRTHandshakePacket.UnmarshalBinary` to
`bytes.Clone(ExtraData)` so decoded handshakes kept on the connection
(`handshake0`, `handshake2`) stay valid once the receive buffer is
reused.

- Refactor the Go proxy for dependency injection: every proxy server,
the bootstrap, the signal handler, the load balancers, and AMF0 now accept
functional-option seams (factories/closures) so tests can inject fakes
without binding real sockets, talking to real Redis, or racing on
package globals.
- Drop the package-global `lb.SrsLoadBalancer`. The bootstrap creates
the LB locally and threads it through every proxy server constructor. Two old
global indirections in `internal/signal` and `internal/rtmp/amf0` are
likewise replaced by per-instance fields.
- Rename `internal/server` → `internal/proxy` and rename the `lb` public
surface for clarity: `SRSLoadBalancer` is split into `OriginService` /
`HLSService` / `RTCService` and recomposed as `OriginLoadBalancer`;
`SRSServer` → `OriginServer`; all proxy server types gain a `Proxy`
qualifier (e.g. `RTMPServer` → `RTMPProxyServer`).
- Extract the Redis client behind a new `internal/redisclient` package
with a minimal `RedisClient` interface and a counterfeiter fake.
- Add counterfeiter fakes (`proxyfakes`, `lbfakes`, `redisclientfakes`)
and ~7.5k lines of unit tests covering bootstrap, memory + Redis LBs, all
five proxy servers, the signal handler, and AMF0.
- Add two new E2E flows — `proxy-e2e-srt-test.sh` (SRT publish through
proxy, verify SRT/RTMP/HTTP-FLV/HLS playback) and `proxy-e2e-whip-test.sh`
(WHIP publish, verify RTMP/HTTP-FLV/HLS via origin `rtc_to_rtmp`) — plus
`setup-ffmpeg-with-whip.sh`, a macOS builder for an ffmpeg with
openssl-DTLS WHIP and SRT support that the two scripts auto-invoke when needed.
- Workspace reorg: move `memory/` and `skills/` to the repo root so all
agent tools (Claude / Codex / Kiro / OpenClaw) share one source of truth via
symlinks. Sync `docs/proxy/proxy-load-balancer.md` and
`memory/srs-codebase-map.md` with the new names.
No protocol, log, HTTP API, or wire-format changes. Refactor only — all
externally observable proxy behavior is unchanged.
