+## EGG DELIVERED OVER THE WIRE (2026-07-05) — headline goal achieved
+
+The real SheepShaver console sent a real mission egg to the real DOSBox pod
+over the emulated network, captured + reassembled byte-perfect:
+- Console -> pod, TCP 1501, **8x ReceiveEggFileMessage chunks** (1040-B
+  NetworkPackets each = 16 hdr + 1024 msg), **7514 bytes total**, declared
+  notationFileLength=7514 (exact match). Reassembled with
+  `net-tools/decode_egg.py`; saved `net-tools/captured_cavern_mission.egg`.
+- The egg is a text NOTATION file (same format as Console.ini). Contents =
+  the operator's actual mission: `[mission] adventure=BattleTech map=cavern
+  scenario=freeforall time=night weather=clear temperature=27 length=120`;
+  `[pilots] pilot=200.0.0.113`; `[200.0.0.113] name=cyd vehicle=madcat
+  experience=veteran badge=VGL dropzone=one color=Grey advancedDamage=1
+  role=Role::Default` + embedded pilot badge bitmaps + ordinal fonts.
+- Confirms the whole decoded protocol end to end: StateQuery/StateResponse
+  poll, then egg chunks, pod ACKs, no `-egg` bypass. **Networking DONE.**
+
+**BUT the pod CRASHES loading the mission** (game-side, NOT network):
+`nn.log` shows `Reference to a page you don't own / PF cr2=FF008B5B /
+Unhandled exception 000E at 00FF:219D ErrCode 0004 / NETNUB Munga exited
+code 14` -- a page fault (wild pointer 0xFF008B5B) in the mission-load path
+right after the egg arrives. Suspects: (a) RIO was DISABLED for this run
+(net_pcap.conf) and the mission sets up the player's vehicle (madcat) /
+controls, which may deref a null RIO/control struct; (b) missing cavern
+content or a pilot-config/badge path bug. Note: cavern/night via `-egg
+test.egg` with RIO ENABLED rendered fine earlier this session, so RIO-off
+is the leading suspect. Real pods run RIO-on headless (no focus stealing),
+so this may not reproduce there. NEXT: retry with RIO enabled + DOSBox
+`priority=highest,highest` (so clicking the console can't starve the RIO's
+ACK deadline during load); if it still faults, disassemble around game
+code 00FF:219D. This joins the Division-renderer/crash workstream.

 ## Open questions / notes
 - Exact TCP listen port(s) — not in the source grep; get from NETNUB.EXE
   or a capture at milestone 3.

+"""Reassemble a mission egg from a captured console->pod TCP stream.
+
+Input: a hex dump of the concatenated console->pod TCP payloads, e.g.
+  tshark -r cap.pcapng -Y 'ip.src==<console> && tcp.len>0' \
+         -T fields -e tcp.payload | tr -d '\n' > c2p.hex
+
+The console delivers the mission as a series of ReceiveEggFileMessage
+packets (decoded from CODE/RP/MUNGA/NETWORK.HPP, wire is little-endian):
+  NetworkPacketHeader (16B) + Receiver::Message hdr (12B: messageLength@+16,
+  messageID@+20, flags@+24) + [egg body when messageLength==1024:
+  sequenceNumber, notationFileLength, thisMessageLength, notationData[1000]].
+StateQuery packets (messageLength=16) are interleaved and skipped.
