research(track-a): trace outbound sequence field provenance

[blakinio]

Draft-only P2 researcher for OTC-20260817-track-a-p2-sequence-provenance.

Base: canonical framing main 0aed48da9a51730c590d0ffe4688f149b359a170.
Exact client: 15.32.df7b29 / 51965216 / e6c244bd39fe2e0632f6f000efd3147164696efa8e901718668e0442325ff7fe.

Objective: trace only the exact producer/update provenance of DWORD(message+0) serialized at f50107; prove or disprove sequence semantics from a concrete update edge.

First discriminator: exact-fenced bounded file window 0xb56d60..0xb57280 for TGameserverDualConnection+0x80, staged source-side without disassembly/semantic classification and decoded only on GitHub-hosted Linux.

runtime_access:none; no world-map, live process, process memory, login/gameplay, raw executable upload or owner-funded AI/API.

Canonical inputs retained:

FRAMING=PROVEN
SEQUENCE=UNKNOWN
COMPRESSION=UNKNOWN
ENCRYPTION=UNKNOWN
FINAL_BINARY_EGRESS=PROVEN_AT_QT_QTCPSOCKET_BOUNDARY

Researcher will remain Draft and coordinator-only promotion applies.

Coordinator disposition: ACCEPT_WITH_EDITS / PROMOTED.

Independent review of exact hosted run 32044825898 verified the producer/update edge for DWORD(message+0). Canonical promotion merged as PR #496 / 8a5fcfd72f2554261eef91a2129c9cc076e730ea.

Promoted classification:

FRAMING=PROVEN
SEQUENCE=PROVEN
COMPRESSION=UNKNOWN
ENCRYPTION=UNKNOWN
FINAL_BINARY_EGRESS=PROVEN_AT_QT_QTCPSOCKET_BOUNDARY
FINAL_SOCKET_OWNER=FACT:TGameserverTCPConnection

For message+0x34 == 3, TGameserverDualConnection this+0x9c is copied into the exact serialized sequence field and post-incremented; the nonmatching branch writes zero. Sequence initialization/reset remains UNKNOWN and was not required for this bounded mechanism proof.

Source final validation: governance 32045117129 = SUCCESS, CI 32045117287 = SUCCESS, CI / Required 95431242465 = SUCCESS, reviews/threads 0/0, final diff 3 files, one-shot workflow removed.

This Draft is historical source evidence and will be closed unmerged. Next frontier: exact type/provenance and input/output semantics of RawDataProcessor member transform 0xb3ec30.
