Summary

  • Add docs/HTTP2_GUIDE.md documenting all HTTP/2 advanced features in the network_system library
  • Covers HTTP/2 client API (http2_client: connect, get, post, put, del, streaming)
  • Covers HTTP/2 server API (http2_server: start, start_tls, request handlers)
  • Documents server-side streaming (http2_server_stream: start_response, write, end_response)
  • Documents client-side streaming (start_stream, write_stream, close_stream_writer)
  • Comprehensive HPACK header compression guide (static_table, dynamic_table, encoder, decoder, Huffman)
  • Frame layer internals (all 10 frame types with classes and usage examples)
  • Flow control mechanisms (connection-level and stream-level)
  • Settings and tuning guide for high throughput and low latency
  • Complete error code reference (14 HTTP/2 error codes)
  • Performance characteristics including stream state diagram (RFC 7540 Section 5.1)

Resolves #686

Test Plan

  • All code examples match actual API signatures in source headers
  • All API tables are complete (no missing public methods or fields)
  • All documentation cross-references link to valid files
  • HPACK static table entries match RFC 7541 Appendix A
  • Frame type enum values match RFC 7540 Section 6
  • Error code values match RFC 7540 Section 7

Verification Results

All 6 test plan items PASSED with 0 discrepancies:

# Item Result Details
1 Code examples vs API signatures PASS All methods across 6 headers verified (client: 13, server: 13, stream: 20, HPACK: 19, frames: all constructors/queries)
2 API table completeness PASS Every public method and field in source headers is documented in corresponding tables
3 Cross-reference links PASS FACADE_GUIDE.md and UNIFIED_API_GUIDE.md both exist
4 HPACK static table (RFC 7541) PASS All sampled entries (indices 1-8, 61) match RFC 7541 Appendix A
5 Frame type values (RFC 7540 §6) PASS All 10 frame types (0x0-0x9) match source and RFC
6 Error code values (RFC 7540 §7) PASS All 14 error codes (0x0-0xd) match source and RFC

Document the HTTP/2 protocol implementation covering HPACK header
compression, server-side streaming, client API, frame layer internals,
flow control, settings tuning, and performance characteristics.
