This string is coming from the following deal:

{
  "Proposal": {
    "PieceCID": {
      "/": "baga6ea4seaqmh37khqbfmvt3phtfsxuz2ok3koypajjxn7gwml26uojmub54kny"
    },
    "PieceSize": 34359738368,
    "VerifiedDeal": true,
    "Client": "f01880278",
    "Provider": "f02118066",
    "Label": "bafybeiadnyv6t65hnwx4as467n4p7k4u6bwsh3dhw24xrahfdwcmpddyo4",
    "StartEpoch": 2867966,
    "EndEpoch": 4359806,
    "StoragePricePerEpoch": "0",
    "ProviderCollateral": "11361143711469027",
    "ClientCollateral": "0"
  },
  "State": {
    "SectorStartEpoch": 2856167,
    "LastUpdatedEpoch": 3106586,
    "SlashEpoch": -1,
    "VerifiedClaim": 18771683
  }
}

When I query https://cid.contact/ with the payload CID from the Label (bafybeiadnyv6t65hnwx4as467n4p7k4u6bwsh3dhw24xrahfdwcmpddyo4), there is exactly one advertisement and it matches the PieceCID.

      "ProviderResults": [
        {
          "ContextID": "AXESIDEKHzzod/XJVEkdEUc1sh9BK3iGFoBtCW75KTCcSF/y",

              "/ip4/154.42.3.144/tcp/24001"
            ]
          }
        }
      ]
    }
  ]
}

However, when I run my Go program calculating Context ID for this deal, I get back a different string - CID bytes are AXESILJcQ2s6OzbQon44jRsuurFgFsXLjRVMpKREU1f0rOwu.

FWIW, this is the DAG-CBOR structure as shown by https://cbor.me:

What am I doing wrong?

It turns out that Boost computes the Context ID from market.ClientDealProposal containing two fields: Proposal and ClientSignature (source code, see also the screenshot below).

Unfortunately, the data provided in StateMarketDeals.json.zst by Glif (presumably a snapshot of Lotus’ method StateMarketDeals) contains only the Proposal but not the ClientSignature.
