Wallet trace — what the Professor maps:

• Initial deposit hashes to the Sigma Primary receiving address at sigmaprimary.co.uk.
• Hop-by-hop forwarding wallets across the deposit chain, captured with chain-of-custody hashes.
• Cross-chain bridge events that move value into the chain where liquidity supports the eventual off-ramp.
• Obfuscation events through mixer contracts and privacy services.
• Centralised-exchange off-ramp wallets — the named counterparty that holds compliance leverage.

The Professor’s off-ramp note:

• Off-ramp endpoint for Sigma Primary resolves to a named centralised counterparty — the venue varies casefile to casefile, but the resolution always names a real exchange wallet.
• Sigma Primary’s off-ramp address is matched against the Professor’s compliance feed and against external chain-analytics datasets.
• The compliance packet for Sigma Primary is structured the way an off-ramp compliance reviewer expects to receive evidence — header, hashes, narrative, ask.
• If the Sigma Primary off-ramp counterparty does not respond inside the published window, escalation routes through IC3, state AG, and civil discovery.

The Professor’s recovery note for Sigma Primary:

1. Read the Sigma Primary submission — written go/no-go returned.
2. Map the Sigma Primary wallet trail — every hop captured with chain-of-custody hashes.
3. Name the Sigma Primary off-ramp — endpoint counterparty identified.
4. Build and file the Sigma Primary recovery packet — to IC3, state AG, off-ramp compliance, civil-discovery overlay.
5. Stay on the Sigma Primary file — until written next steps exist.
