Server sends GOAWAY with ENHANCE_YOUR_CALM (0xb) error code
Classification: NOT VULNERABLE — protocol-layer enforcement is active
Meaning: HTTP/2 implementation has proper rate-limiting controls

50%+ of connections terminated via TCP reset
Classification: LIKELY PROTECTED — verify with edge/infrastructure team
Meaning: Edge appliance or DDoS protection engaged at transport layer

Per-second reset rate drops significantly over time (late buckets <60% of early)
Classification: PARTIAL PROTECTION — confirm with infrastructure team
Meaning: Server or edge slowing the attack adaptively

Server sends REFUSED_STREAM (0x7) responses
Classification: PARTIAL PROTECTION — review rate limits
Meaning: Some stream-level rate-limiting in place

No ENHANCE_YOUR_CALM GOAWAY, no TCP resets, no throttling detected
Classification: VECTOR EXERCISABLE — exploitability unconfirmed
Important: This doesn't prove DoS exploitability. Edge volumetric/behavioral 
protections (Akamai, CloudFlare) may engage at higher scales

============================================================
ENFORCEMENT SIGNAL ANALYSIS
============================================================
Server SETTINGS (initial frame):
  HEADER_TABLE_SIZE = 4096
  ENABLE_PUSH = True
  MAX_CONCURRENT_STREAMS = 128
  INITIAL_WINDOW_SIZE = 65535
  MAX_FRAME_SIZE = 16384
  → MAX_CONCURRENT_STREAMS=128 is conservative (good post-CVE default)

GOAWAY breakdown across connections:
  ENHANCE_YOUR_CALM (0xb): 3/5
  Other GOAWAY codes:      1/5
  No GOAWAY received:      1/5
  TCP reset (RST at transport): 0/5
  Total RST_STREAM frames from server: 2
  REFUSED_STREAM frames from server:   0
  Connections showing adaptive throttling: 1/5

============================================================
VERDICT
============================================================
✅ ENFORCEMENT CONFIRMED
   3/5 connection(s) received GOAWAY with ENHANCE_YOUR_CALM (0xb).
   This is the canonical signal that the CVE-2023-44487 mitigation is active.
   Classification: NOT VULNERABLE — protocol-layer enforcement is engaged.
