Terminal disposition

Researcher source for OTC-20260818-track-a-s2-player-inbound-static.

Final researcher head: d0c78772294cd6355221cce96f499b85fb7738cf.

Coordinator review accepted the bounded result and promoted it to main via PR #513, squash merge 592e193a5ada1c40d23193038f350e23c539898b.

Canonical promoted result:

TPlayerProtocolMessageHandler QMeta identity/table = PROVEN
receivedPlayer* direct QMeta ownership by TPlayerProtocolMessageHandler = DISPROVEN
TProtocolMessageQueue received-player owner = PROVEN
five exact typed player receive signal contracts/stubs = PROVEN

Still intentionally UNKNOWN:

network decoder -> queue signal emission
queue signal -> connected receiver/member
handler -> TPlayerData mutation
TPlayerData XYZ candidate as inbound/runtime authority

Source final exact-head validation: Track A governance 32116406977 = SUCCESS; CI 32116407136 = SUCCESS; CI / Required 95646841777 = SUCCESS; reviews/threads 0/0.
