staked 278,192.42 AVAX on NodeID-FTbhiFzLkcsfs1nMQ4zrkeqnmuRthWdV7 on 1 Jan 2026 and exported 100,068.46 AVAX at 00:08:03 UTC on 30 Jun 2026; not validating at the 16 Sep read, and where its AVAX went is not established
Evidence: scratch/hunt/blue/custody-batch.md: a walk of 10,670 P-Chain blocks with platform.getBlockByHeight over three windows found nine AddPermissionlessValidatorTx of 100,000 AVAX or more in the 1 Jan 2026 re-stake window sharing one fingerprint: a 100 percent delegation fee, a threshold-1 reward owner equal to the staking key, and an end at an exact month-end 00:00:00 UTC. Three walks of the same 68,196 blocks by two sessions return those nine and no tenth. The cluster is now matched to filed quantities at three dates by that one method: the nine stakes sum to 8,284,248.39 AVAX against the 8,329,871 AVAX filed at Coinbase Custody at 31 Dec 2025, which is 99.452 percent; 8,416,336.28 AVAX against the 8,462,227 AVAX in the 424B3 at 31 Mar 2026, which is 99.458 percent; and six of the nine exported to the C-Chain between 00:08:02 and 00:09:05 UTC on 30 Jun 2026 summing 4,458,518.01 AVAX against the 4,510,207 AVAX filed at 30 Jun 2026, which is 98.854 percent. On the refined fourteen-wallet set, read as C-Chain balances at the filed instant itself, the two testable dates read 99.9878 percent (gap 1,015.83 AVAX) and 99.9779 percent (gap 996.01 AVAX). The cluster is matched to the filed quantity at three dates as a set, which is an inference and not a proof: the tie to this key is collective and arithmetic, not a flow, and no member is pinned on its own. The June 98.854 percent is a subset-sum fit from a 63-second export window, which cannot see a stake that spans the filed instant; at least four fingerprint keys held 1,647,622 AVAX across 30 Jun 2026 and are excluded by quantity alone (scratch/hunt/blue2/SEARCHES-2.md sections 2.1 and 2.2, from tenth-member.md and batch-counterparts.md). Re-run: POST https://avalanche-p-chain-rpc.publicnode.com platform.getBlockByHeight across 23:30 to 01:30 UTC around each month end, then GET https://data-api.avax.network/v1/networks/mainnet/blockchains/p-chain/transactions?addresses={key}&pageSize=100 (glacier-api.avax.network answers 429 to unkeyed callers; data-api serves the same routes). Its C-Chain counterpart is 0x8CADa8839c830e6f67a5E6837CBD0477E9c2384E, which held 100,068.3557 AVAX at block 89,166,730 and paid the whole of it to the cold wallet 0x720efa4a on 2 Jul 2026 (scratch/hunt/blue2/batch-counterparts.md sections 1, 2 and 4).

How this row was graded
- Evidence class
- C, filed-quantity match
- Confidence
- 0.70 on a scale of 0 to 1
- Customer
- AVAT
- What would promote it
- restated, because the written condition can no longer decide it: the July destination is 0x720efa4a, a Coinbase Custody cold wallet the registry already carries at 0.80 inferred, which is neither the AVAT trail nor anywhere else. The money stayed inside the family, which is consistent with membership and is not the flow tie the old condition asked for. What would promote it: an outflow into a wallet the registry grades proven for AVAT with no omnibus between, or a filed quantity matching it to the unit
- What would kill it
- paying a wallet tied to another named entity
